LED tube price high is the universalization obstacles, price factor decided the cost of LED tubes superiority and the price could let mass acceptance, is to influence LED lamps and lanterns to replace the traditional lamps and lanterns is one of the important factor.

The actual LED chip cost only 15%, other costs to packaging, heat to the main structure, cost, power supply. From the composition of the cost to reduce the cost of lamps and lanterns is in manufacturing process, simple request LED chips is not a too big reduce the role. Lamps and lanterns manufacturing need whole reasonable price, reasonable planning, comprehensive simple request a certain part of the cheap effect is not big, but we design the lamps and lanterns of the overall structure to the economy, is the most important optimization.
With technology, LED chips using larger size increase wafer production process, the cost will be constantly in recent years, the rate of 20% per year in lower, LED chip prices factor, will also included in the ascension of the efficiency in the lower prices, the same price to buy a better product. LED chips 15% proportion, it was reasonable, will continue in this level.

LED the price of take a package cost proportion, about 50%, we must choose the more appropriate LED package structure. Cree, Lumileds, OSRAM existing encapsulation are not accord with lamps and lanterns to design, design cost will not high. The bold innovation design is the product design way out, mostly we use copying or big company seal structure thinking and innovation too little, to their own creative lack of confidence. COB is the future lamps and lanterns design mainstream way, according to the lamps and lanterns optical requirements COB packaging, as well as reduce secondary optical design cost. Packaging costs in the total cost of the lamps and lanterns of 20 to 30% only is more reasonable.

The actual cooling the design is simple, held two direction:

1, LED chip and the cooling device path more short more good, the short your heat, the better the design;

2, thermal resistance, is to have enough heat to path also want to have enough ‘road’. This part of the heat in structure, used for major cost cooling costs is not much.

Heat dissipation cost to maintain at 20%, 20% think very reasonable cost, the biggest problem is how to have more innovation, design more reasonable. Structure design in lamps and lanterns to be about of the power supply is LED lamps and lanterns is the weakest link, lagging development LED lamps and lanterns, to improve quality. Now accounts for 20% of the cost of lamps and lanterns design or so, some high. As technology development in about 5-10% power the most reasonable.

Halogen lamp: belong to incandescent lamp light source, that is woven in white in the halogen gases filling, making the light source the performance improved, photosynthetic efficiency from 8 LM/W increase to 12-15 LM/W, greatly reduce the volume of light source, can suit more lamps and lanterns use; Life from 1000 hours to 3000 hours increased to 2000; But its always belong to thermal radiation to shine, and smooth effect has been to not up, now in the world scope are limiting the use of; High heat, light failure is serious; The light with ultraviolet radiation, long exposure to textiles, jewelry and jade surface discoloration. Fade
LED spot light: semiconductor emitting diode technology; Currently lighting applications efficacy 100 ~ 120 LM/W; The service life of 30000 ~ 50000 hours; High photosynthetic efficiency high show color sex; Cold light, no radiation and ultraviolet radiation;
A comparison, flux
Halogen lamp cup usually have three specification: 20 W, 35 W, 50 W, we can use 3 by 1 W, 5 × 1 W, seven by 1 W lanterns day to replace.

Halogen light cup (LM) power flux LED lamp power flux (LM) note

50 W 547.50 5 7 W 76.65 0.5
Note: this power consumption for three years, the value of the cycle decorate (3 years by 365 days/x 10 hours/day in); Halogen lamp normal life for 2000 to 3000 hours, LED lamp normal life for 30000 to 50000 hours.

Conclusion: LED spot light in the shopping mall, stores and other places alternative halogen shoot the light is energy efficient, zero maintenance cost, no heat, no cold light ultraviolet radiation, no damage to the product etc, and replace halogen shoot the light is imperative.

Mainland led industry in recent years, however, the high speed development into flocking to join led the market, industry and investment funds, the huge hot trend in second half 2011 facing market stall, the recent crisis led industry are pointed out, the mainland led industry is about to get to the knockout, about 1 into enterprise will face to quit, the mainland XinGuang electricity exit led cointegration epitaxial industry, the mainland shenzhen led FengZhuangChang junduoli also appear without warning collapse, Taiwan factory privately said, the mainland market mines, have a bit inadvertent will face in the debt collection, Taiwan is the sackings factory.
According to the points out, junduoli won China shenzhen optoelectronic industry 10 strong enterprises, and in sichuan province, all have to put those investment to LED lighting business opportunities, but company officials default on more than 200 employees and a monthly wages, and owe the bank debt, suppliers, 11 eve in tens of millions of suddenly gone missing, the LED industry comes out, and part of a factory may not receive end the money, will recognize losses, but including LED grain factory crystal electricity, ladies first round companies are pointed out, and junduoli and no close contacts with early, not affected by it.
The industry says, in the official support LED lighting, mainland LED industry in recent years, with the excess investment makers, now about 90 have LED grain factory, but also has about 9 into losing money, as for the downstream packaging application factory numerous, size is differ, uneven, and the market demand by 2011, according to the industry downturn affect mainland statistics, foshan city in guangdong province in the 50 stores in LED lighting makers, 2011 order reduced on average 10 to 30%, but the enterprise production cost? Yu) W rose 30%, 7 into enterprise profit declined.
Because since 2011, mainland for 12 times the central bank to raise deposit reserve rate, 21.5% of the level is not only a record, in a bank monetary pressure, more smoke house industry appear fund revolving problem, expected in the = junduoli incident, fear will barrage appear out of events. Collapse
But for the mainland authorities LED lighting policy direction invariable, including mainland China 1025 planning, LED lighting is expected to will account for 20% of the whole lighting proportion, will drive the mainland LED lighting domestic market, in addition, the rapid rise is expected by the end of the mainland authorities also announced the subsidy policy LED lighting, including the Treasury Department in conjunction with the national development and reform commission, is expected to LED lighting products to subsidize, will start to priority indoor illumination and commercial lighting products subsidies, such as canister light, and shooting, shoot the light, and gradually expand the scope of subsidies.
LED operator said, LED lighting products cost per lumen ($/ lm) annual decline in average about 20%, and in recent years has accelerated the trend of the cost down. According to the energy department is forecasting, white LED encapsulation lumens cost will be from 2009 in 25 $/ KLM, descend to 2015 years of 2 $/ KLM, average annual costs fell by more than 30%, and in 2010 ~ 2012 years at an average annual rate of nearly 40%, therefore fell by 2011 to 2012 will be LED and traditional lighting down the fastest time of price, it will also mean that LED industry will enter the integration of merger, Taiwan industry I’m afraid this trend will suffer.

As energy conservation and environmental protection industry, led lighting in not long ago the state council issued the “1025″ comprehensive work of energy saving and emission reduction plan “policy concern is. The plan explicitly pointed out to speed up the facilities, strict energy saving transformation with can management, the guidance consumption behavior, and to promote the use of residents in energy efficient appliances, lighting products. And will “semiconductor lighting” into “increase energy conservation and emission reduction technology industrialization demonstration” project.
The reporter understands, in the current price of phosphor 10 times growth, energy-saving lamps of surprise at cost, LED lamp recently because the price but chip and prices continued to continue. This trend is LED lighting breakthrough market provides moments bottleneck.
The personage inside course of study thinks, this will further move LED lighting applications market, accelerate the LED lighting demonstration application and popularization, to the end of the 2015 China LED lighting is expected to reach even more than 20% penetration.
LED lighting will meet big industry reshuffle
The data show that in 2010 the global LED lighting application products market scale for 4 billion us dollars, up 40.4%, and the rapid growth. Expected in 2014, global LED lighting application products market scale will reach $62.5 billion in 2010, 15 times, a compound rate of 73.3% in.
“1025″ period, LED light source technology in our country is included in the strategic new industry. China is estimated to total illume to power in 2010 in China, 12% of the total capacity of up to 3 trillion degrees, and if semiconductor lighting into a third of lighting market, can power saving 30%, namely the annual energy saving 100 billion degrees, at least equal to the capacity of the three gorges project.
Authority figures for 2010 show our country LED to 126 billion yuan, the scale of production value in 2011 is expected to rise by 50% to 180 billion yuan or so, the LED industry investment scale will reach 65 billion yuan. Many manufacturers began to focus on the LED lighting products production, also there are many traditional lighting enterprise on the road of the transition.
And in the near future, the relevant statistical data show that in 2011 to July 1, LED industry in China is the total amount of investment of the new plan has reached 125.618 billion yuan, of which more than 40% of the capital to DuoGe industrial links, even for the whole industry chain investment. More attention is, the LED into the enterprise the LED industry LED industry investment has become an important part of their investment, this kind of project investment projects of all the proportion of the amount to more than 45%, more than 65% of the total investment amount.
In a series of Numbers, is the industry and behind the policy to promote the prosperity of the party market power, the future the vigorous development of LED lighting industry has been irresistible. Industry in the expert analysis, compared with the traditional lighting products in the future for a certain time period, the LED industry development pattern will remain stable, still in channels give priority to, this is the whole lighting the inevitable trend of the development of the industry. When a industry developed to a certain stage, shuffle is necessary to improve the process industry. As for an enterprise that too, and developed to a certain scale enterprise go up again will meet all kinds of bottleneck.
The expert thinks, the current domestic enterprise is in the government encourage LED support for fast development, while the next LED lighting will serve as a new energy saving light source, was quickly consumer approbation, into the average homes, including the bottleneck of the products to be breakthrough categories, specifications, price, brand and marketing mode, channel construction, etc.
SONY chief engineer LuoWenZheng light source that LED products and technology, because, in the future trend similar 3 ~ 5 years, LED lighting products will gradually normalization, standardization, become a normal product, and this time also will gradually have LED the industry reshuffle.
Backward in technology into “short board” enterprise in many industry chain downstream
On the surface, LED lighting industry development hitting its stride, however, prosperity, and then worry behind the surface.
LED lighting market as a big “cake”, brings in eight people to come to the party points rewards. However, many people just want to fish in troubled waters, but also some short term profit. As the world’s largest market, China’s upper reaches of LED lighting technology weak become a piece of shortcomings. The 2010 high brightness LED the market review and outlook, said the report, in 2010 China LED manufacturers of global high brightness LED the market only 2% of the total output value ratio, and related technology still lag behind the international leaders about three to five years. Our country LED chips and device products mostly in small power and perfection of field. Domestic chip although can be purchased for 1/10 of the import chip, but less than 10% of the domestic market. In addition, high brightness LED chip, the device type power more than 80% are dependence on imports. Extension with key equipment production MOCVD and extension of substrate, sealing a high performance the silica gel, the epoxy resin, phosphor and other raw materials to basic rely on imports.
And the industry in the whole industry chain, analysts say, the upstream of the highest profit. And the core of the patent technology concentrated in Japan Nichia (day and), Cree (American families sharp), Osram (Germany Osram) a few overseas giant hand. In the field of extension and chip, the United States and Japan enterprise also is in the monopoly advantage, took more than 60% of the profits. Most Chinese enterprise, can be in only LED to the end of the chain, assembly field for the remaining 40% of the profits, a lot less than LED enterprise depend on the government municipal engineering survive, with earnings. Subsidies
At present, the LED lighting in urban lighting construction, decorative lighting hotel, etc are increasingly popular. LED the pace of development of though clearly faster, because of the lack of the relevant standards, have experts worry that the market will because the quality of products and become chaos. The other according to relevant media reports, some local LED lights for the light failure, serious has been removed.
In addition, the price also once is enterprise “sell” LED lighting the headache. In a lamps and lanterns wholesale city, a dealer introduces to the reporter, “we generally do not love to sell LED lamp. For the price of real and LED energy-saving lamps, incandescent lamp gap is too great. For example, 3 W LED lighting price 20 yuan, the W is 90 yuan, and energy-saving lamps as long as 10 yuan, incandescent lamp only need to pay $1 more; and in unusual, it seemed, a single people two bright LED lamp energy saving effect was irrelevant.”
“The Chinese people in the house, a few lights in the refrigerator, big home appliance such as the power consumption than lining, illume to seem tiny. So, if there is no government guidance, even if you LED lamp life energy saving effect, again good, want to open the market also need a very difficult process.” Another market participants say.
Subsidies are expected to move 2, 3 class market
In 2009, the Taiwan affairs office set up the lead the cross-strait industrial coordination team, and selected semiconductor (LED) lighting the cross-strait industrial cooperation as one of pilot projects. Then, the national development and reform commission (company founded the ring led semiconductor lighting on both sides of the Taiwan straits cooperation project coordination team and a working group, launched a series of works have results.
At present, not only on both sides of the Taiwan straits in LED products than standard tests and testing, product reliability research cooperation effect, also common organized the LED lighting products application demonstration projects, and selected xiamen torch development zone for high technology industries LED street lamp application engineering, guangzhou metro line 2 at the LED lighting application engineering as a demonstration project. The project a big boost the production capacity of the LED lighting industry.
According to a person familiar with the national development and reform commission, the ministry of finance and the competent departments such as coming to semiconductor lighting products, is expected to start the fourth quarter subsidies, will be preferential start for indoor illumination and commercial lighting products subsidies, such as canister light, shoot the light, then gradually expand the scope of strength and subsidies.
It is reported, the national standardization management committee has already completed LED the national standard of 23 for advice work, the personage inside course of study thinks, this for the implementation of the subsidy cleared the standard environment barriers.
It is revealed that the subsidies to energy-saving lamps and early LED lighting common promotion, and then gradually expand the scale and share LED, compression of energy-saving lamps subsidies share and strength. “Subsidies as more is move the leverage of application of the market.” Person said, “this will not only promote the level of the market of semiconductor lighting applications expand, and can drive two, three line market commercial lighting start.”
As technology advances brought the continuous decline in cost, and local government subsidy policy in place, LED products and energy-saving lamps price gap is expected to further narrowing, this will help open the terminal market, fundamentally relieve excess capacity expected pressure chip.
“Two years ago 1 watt LED chip prices is probably three dollars, but now has fallen to less than $1, some in Taiwan and the mainland of the chip cheaper, even 3 RMB a grain.” Industry sources told reporters. May begin production LED chips as the auspicious light electric controller tells a reporter, “probably in a recent years, chip prices more than 6 piece from down more than $2 yuan.” According to introducing, chip accounted for at least a third LED lamp cost reduction drive, chip directly LED prices fell. “This will allow LED lights are more consumers faster receive, direct drive LED lamp market share of ascension and popularity.”
In addition, the current domestic existing enterprise into LED equipment and raw materials, field note is that this kind of enterprise in the field in the initial stage, the future technology level and so on various aspects still needs to be improved.

In emerging applications market appear constantly drive, the size of the market in recent years LED to rapidly promote. In 2005 China LED to 26.21 billion production has only, the size of the market is exceeding RMB ten billion to 11.49 billion yuan.
Application: the display is a main application market LED widely used, booming.
Our country the LED display market started earlier, appear on the market the a number of very strong strength of the LED display manufacturers. At present, the LED display screen has been widely applied to the station, Banks, securities, the hospital. In demand, the LED display on the LED indicator light after LED second, accounting for 23.1% of overall sales LED. Because of the screen in LED for brightness and life of the demands of the higher than the average price in LED indicator light, LED indicator light above, leading to use LED display screen size of the market reached 3.24 billion yuan, more than light top become the main application market LED. With unique advantages, full-color LED display screen is widely used in stadiums, the town square, concerts, station, airport and other places.
Application 2: small size back light market is slowing, cuhk size will become new concerns.
LED by mobile phone in application already mainly small size LCD panel market, mobile phone output backlighting the continued growth of the spurs the back light the rapid development of the market. In 2003, the emergence of the mobile phone is labeled white LED to promote the rapid development of the market. But as the mobile phone output into a steady growth stage and technology to improve for mobile phone LCD panel back light LED the decrease in the number of mobile phone, make in LED in the back light dosage growth is slowing, 2005 back light LED more than 1.2 billion only with the number and in a few years the rate will remain in the singly. The slowdown in growth number and the average price of the declining, eventually lead to small size back light market growth weakness, and at the same time, cuhk size back light market for the manufacturer to be bestowed favor on newly though, but in 2006, also cannot form scale. In the above two factors influence, back light market will appear in 2006 1% of negative growth. 2005 years back light the size of the market more than 1.5 billion yuan.
Application: three auto lamp great market potential, but the short term market is hard to start.
In 2005 China automobile application market scale LED to 029 million yuan, of which, auto lamp the size of the market for 021 million yuan. From the whole LED application market look, automobile application market is still in the bud, the size of the market is very small.
LED as auto lamp mainly because of low power consumption and long service life and the corresponding speed characteristic. A statistics show that, in the car to 100 kilometers per hour, driving with LED the brake lights vehicles didn’t pack LED a brake light vehicle braking distance will reduce 7 feet. At present, has been gradually applied in automobile LED the third stop light. Although LED at present is also facing unit wattage low lumens and related policy the limitations in into the automobile tail light and headlight market still needs some time, but as the cost of performance than the decline and to promote the efficiency of light, and eventually LED will gradually realize the car interior, hind to from the front of the transfer, and eventually holds whole auto lamp market. With the great capacity, car LED lamp market is facing a huge development potential.
Application: indoor decorative lamp four market has gradually start, the traffic lights market entry smooth growth.
Indoor decorative lamp is another market LED emerging markets. Through the current control, LED can realize even hundreds of thousands of color changes. At the present stage of individualized era, exquisite LED diversified colors help LED lights the development of the market. LED has started to make small decorative lamp decoration, curtain wall in the hotel, the bedroom application. 2005 years of interior decorative lamp market scale to 158 million yuan.
After DuoNian replacement work, major cities in China from traditional traffic lights to replace the traffic lights work has LED to a close. LED traffic lights market had DuoNian high-speed growth in 2005, after market scale to 1.52 billion yuan. But as the replacement of the work finished, LED the traffic lights will not maintain market growth, expect 2006 LED the traffic lights only realize the growth of the market to 5.8% to 1.61 billion yuan. Application: lighting market five landscape fast development, the market in 2007 growth peak.
The landscape lighting market mainly in the streets, squares and public places such as decorative lighting is given priority to, the main driving force from the government. By the 2008 Beijing Olympic Games and the 2010 Shanghai world expo, the influence of Beijing, Shanghai and other site accelerated the pace of the landscape lighting, due to the low power consumption, electricity use in LED the landscape lighting huge market has a strong market competitiveness. At present, the LED have been more and more applied to the landscape lighting in the market. In 2005 China landscape lighting the size of the market more than 700 million yuan, in the above two main activities leads, the landscape lighting in the market will reached 72% in 2007 high growth rate.
In addition, the Olympic Games and the world expo is no longer the main role in their own drive landscape lighting the growth of the market, the more important is the role model. In order to meet the Olympic Games and the world expo held, Beijing, Qingdao, Shanghai, etc will be built into a group of LED lighting project, the project of the landscape of the street in adornment also will play a role model. Other cities in the landscape lighting in see LED the excellent work will reduce the use of the landscape lighting for LED worries, speed up in LED lighting use landscape application. LED will be from level 1 to secondary, tertiary urban rapid urban expansion.
Five: general lighting market application a long way to go, shoulder heavy responsibilities.
For general lighting into markets, power except face such as white LED the luminous efficiency is low, the heat is bad, cost a higher problem outside, still will face to the optical, institutions and electronic integration and LED lighting products in the formulation of standards. To solve the above problems need to be very long period of time, sadie consultant LED in the 2010 years ago is expected to cannot enter general lighting market.
Because the hotel, business center, high-grade commercial office buildings and other commercial place relative to the susceptibility of the price is low. At the same time these high-grade sites focused more on reveal grade and exalted position, for the new products have more interests in degrees. These are reduced the LED lighting into the threshold. Sadie consultant LED lighting is expected to enter the business will take the lead in the market, gradually to civil market expansion.
The LED display basic knowledge
Modern society has entered into the information age, information dissemination plays more and more important position, and people to the requirements of visual media is higher and higher also, demand media responsive, reality (real-time), eye-catching (rich colors, vivid), the picture of large, powerful, in recent years, along with the microelectronics technology, automation technology, the rapid development of computer technology, semiconductor technology matures, lead to LED display point size more and more small, resolution, and more and more high light will show the three colors (red, green, blue) integrated into an organic whole, to achieve full color effect, so that the LED display application scope is expanding.
The LED display characteristics
Leds are light emitting diode (LightEmittingDiode), is the abbreviation of photoelectric applications in the field of the luminous display is widely used material, choose different materials in certain conditions can be red, green, yellow, blue wait for color, LED with the following features, make it become the first choice of making big screen material:

Projection full color screen brightness low, can not in fine outdoor use clarity, poor (picture by light not divide evenly)
CRT full color high cost, power, the area can not be too big
PDP full color screen exquisite and high cost, the perspective is small, the area can not be too big
The classification of the LED display
According to the application according to the application of classification place place, LED display different can be divided into two kinds of indoor and outdoor.
Indoor screen used mainly for indoor production process, in the first first light-emitting grain to make dot matrix module (or digital tube), then the module for a certain size joining together that unit board, according to user requirements, to display unit board as the basic unit joining together into the size of the user to need. According to the size of the pixels, indoor screen divided into Ф 2, Ф 3, Ф 3.75, Ф 4.8, Ф 5, Ф 8, Ф 10, etc.
Outdoor screen should
Mainly used for outdoor, in making technology first first light-emitting grain encapsulation into a single light-emitting diodes (leds), called a single lamp,
Used to make outdoor screen single lamp typically use the role of reflective glass has contracts to to increase brightness; Again by more than one single lamp packaging to a single LED only pixel tube or module, and the pixel pixel tube or die of dot array of pixels display unit case, according to the requirements of the customers and display application field to a display element cabinet as the basic unit need size. Cabinet in the design should be sealed, in order to achieve the purpose of waterproof and fog to fit the outdoor environment.
According to the size of the pixels, outdoor screen divided into Ф 11, Ф 14, Ф 16, Ф 19, Ф 21, Ф 26, Ф 36 and specifications.
According to gezer classification
According to the LED color, can the LED display will be divided into the single color, double colors, full color 3 kinds.
Single color should
Each pixel is only one color, with red, because most of the red light, high efficiency can gain higher brightness, also can use green, also can be mixed color, that is, in part, with part of red green with yellow, part of.
Should double colors
Each pixel have red, green, and two gezer, stacks, a yellow in gray scale control, through the red from green gray change can be combined from up to 65535 colors. Should full color
Also called three colors, each pixel have red, green, blue three gezer, in gray scale control, through different shades of red, green, blue change can be really 10 the colour of nature, combined from 16777216 colors.
According to the function classification
According to the function of the screen, can be divided into the LED display screen, graphic article screen, videos and digital screen
Four.
Article should screen
This kind of screen display text, it is mainly used for 16 X16 bring itself or 24 X24 bitmap fonts, can work independently, can use remote
Controller input Chinese characters, can also with computer online, through the use of computer send information. It could be work. Because this kind of screen made more, is called a bar screen.
Graduate from professional graphic screen
This kind of display mainly used to display text and graphics, generally no gray control. It through the communication with the computer input information. and
A screen, the advantages of the screen than pictures is to show the font, font rich and can show graphics, videos, text screen compared with the biggest advantage is that a computer can control of screen, and it could be displayed.
Tap should
This kind of display screen like yuan and control computer monitors like a one-to-one mapping relationship yuan, gray scale control, so its watch
Now force is extremely rich, with multimedia card, still can play video signal tap. Videos, real-time reflect open computer monitors show.
Digital screen should
The digital screen is the cheapest of the LED display, widely used in Banks exchange rate, interest rates display, hotel room rates price list, seafood
Table, etc. In most cases, in the digital screen article on the screen to make up for the digital screen can’t show the shortage of the text.
Mixed screen should
Dot matrix display, digital mixed namely it is used for most the securities market shows.

Led domestic market prospects at home and abroad, leading to downstream industry chain integration led enterprise merger fast pace, attract numerous investors have entered this field, the investment industry appear again, at that time the climax of the domestic various lighting products in the market.
Compared with the previous year, the market condition, this year LED investment boom is LED on, a lot of the state version cooling lighting giant high-profile face no longer, but the propaganda LED industry the direction of energy-saving lamps, but turn key or on the LED, by the guidance of national policy, after all, LED light source energy saving, all is the future developing trend of the lighting.
LED the chaos of the market by another reason for this is that investors of the blind, the other a brief more important reason is the maturity of the technology market enough. In a domestic LED lighting products in domestic sample inspection, LED efficiency is poor, show color sex are low. And the chip main sources of rely on imports, so in the cost of the product will become even more big. Compared with the same brightness LED, the price is high, it make to and energy saving, and weakening the LED to consumers than the attract strength.
Provide the end of the high price of core competitiveness, lack, and filled with defective lighting market in the face of the foreign capital enterprise, competition, many local market advantage also become without. However, in light of the enterprise a new starting point, only in a break the bottleneck of the technology, to find more way out, this is LED the development of the industry a trend, and only the independent innovation development core technology, to lead others in lighting market step.

“Ten city lamp” implementation for more than a year, many enterprises LED lights, and focus on development and commercial lighting market potential is bigger, application scope and more higher growth. The hotel, bazaar, supermarket business places common lighting products including T8 ZhiGuanXing fluorescent lamps (hereinafter referred to as T8 fluorescent lamp), along with the emergence and its advantage LED gradually revealed, place of business to replace the traditional source of light use LED pace faster and faster. From energy saving, price two side, a long business need illume time place can use LED the Lantern Festival is more obvious advantage, can input in a short period of time recovery. We are here to fluorescent light and LED GuanDeng T8 for commercial lighting the simple economic and technical analysis for the industry, reference.

Table 1: with a certain type of fluorescent lamp T8 LED GuanDeng parameters CRT (data sources: the energy efficiency of xiamen lighting technology analysis and engineering application research summary report “, a certain type of third party LED GuanDeng test report)
Xiamen commercial electricity price is 0.98 yuan/degrees, and, in doing so, electricity price analysis, can work out what the ShiYongBiao 1 the LED GuanDeng alternative WT8 36 in 5375 hours in fluorescent light can withdraw cost, less than half of life cycle of fluorescent lamp T8. If used for 24 hours, the commercial lighting place cost can be recovered less than eight months, used for 16 hours commercial lighting sites need to 11 months, used in 8 hours commercial lighting sites need to 23 months. Every day in the lighting time to grow more, the shorter the capital is recovered.
GuanDeng LED into commercial lighting the trend of the market analysis
LED GuanDeng contrast T8 fluorescent price is higher, photosynthetic efficiency advantage there is not obvious two big problems, this is the most attention, is also the user LED many enterprises in the industry are the task of research. With LED technology, material of development, these problems will be solved step by step. Figure 1 is PIDA sort of white LED to the development of technology and cost forecast.
Suppose a year return period is the place of business users are willing to use GuanDeng LED the premise of fluorescent lamp replacement T8, considering only photosynthetic efficiency and cost of the effects of changes, including thought the whole lighting effect for 70% of the components, LED efficiency LED components cost 60% of the total cost for lamps and lanterns in 5 years constant. According to the table 1 and figure 1, according to different requirements of the commercial lighting lighting time place,

(note: red, pink, blue line in 24 hours, respectively said 16 hours, 8 hours commercial lighting place, can accept alternative to 36 WT8 fluorescent LED GuanDeng maximum price, the yellow line said LED technology development to bring alternative 36 WT8 fluorescent LED GuanDeng cost down trend)
The above can deduce that LED GuanDeng available in 2011 years after 24 hours into mass commercial lighting place replace T8 fluorescent, after 2012 alternative 16 hours of commercial lighting place 2014 years on fluorescent, T8 alternative 8 hours of commercial lighting places fluorescent, basic entered the overall T8 alternative commercial lighting in the stage of fluorescent lamp T8 place.
Figure 2 conclusions and the table 1 have difference analysis, on the one hand, technology development and cost more than forecast to decline, the real price of price and predict the large gap, On the other hand, table 1 quoted LED GuanDeng high cost performance, and with little power LED, with little power LED explain that some manufacturing high performance and price ratio of the GuanDeng has LED into commercial lighting can place, this is some enterprise such as GE, Philips, Osram, the three big lighting giant and matsushita electric, sharp, honeywell international big enterprise can lang is going into the market.
Figure 2 just simply from an ideal state of a rough estimate GuanDeng LED, the process of fluorescent lamp replacement T8, in fact, and many factors affect the new light source to the pace of the overall market, maybe a new technology or a successful application will greatly affect the process.
Of course, the process of the development of LED many questions need to be overcome, and fluorescent lamp also have more efficient T5, T4 is gradually replace T8, but it is undeniable that LED into commercial lighting market has mass will come soon. Can simply inference, the next five years, will be a commercial lighting market fluorescent lamp and LED lights were market, but T8 will gradually exit commercial lighting field.

With the advanced countries, such as Europe, America, Japan, the mainland out than incandescent lamp is relatively slow, and progress in Europe and the United States about 2 ~ 3 years’ time, incandescent lamp knocked out, Japan will gradually is directly in 2012 disable all incandescent lamp, and mainland of incandescent lamp eliminated program is for 4 ~ 5 years time, the mainland for energy saving lighting technology and standard has not yet in place, replace incandescent lamp with energy-saving lamps easy cause pollution, and the price of LED lights and made consumers hope it stop.

The mainland 5 W LED light bulb price is 20 times of incandescent lamp, fluorescent lamp of more than four times as much for consumers, is hard to accept price, and lack of perfect the standard and core technology, fear will influence the popularity LED light bulb. But after the disabled, will be incandescent lamp to bring huge LED lighting business opportunities, the market potential is still cannot small gaze. LED light bulb and energy-saving lamps, compared with longer life expectancy in color, perform better on sex and not cause environmental pollution and other advantages, whether to the appropriate price, can affect the popularity of the biggest is key. Mainland investors believe that LED light bulb need at least to RMB 30 yuan, get on the market foothold.
