How to Improve LED Lighting's Energy-saving

LED lighting is the biggest selling point energy saving, but often the market limited to the cost of the product, materials, and cooling technology, makes the energy saving the appeal for the efficiency of the light and the discount factors. Energy saving at present mainly reflects in the following two aspects:

A, the maximum energy into light energy;

Second, the light maximum control to fit for human senses.

From now LED application field with the problem to see, the above two apparently isn't good enough. First is the "hot" problem LED, now that exist heat dissipation problems, that means the yield of LED heat is considerable. We can be simple to analyse the problems and LED what LED the heat produced in the:

1. Now that LED to the yield of high quantity of heat can influence the Angle of heat, temperature is obviously. About LED light source sealing glue, what kind of material to withstand the heat for tens of thousands of hours baking? Of course even have such high quality material, but high prices will let people money.

2. The problem about life, actually very simple, LED chip heat release LED light source itself can affect the life expectancy, lead to light failure; In addition, still can affect LED lamps aluminum plate board of life.

3. It is for LED lamp heat generation, so need to heat dissipation. The lighter than plastic, metal, the thermal conductivity is much better, but also much more cumbersome, of course, also more expensive.

Next is the light sensor. Why in the GaoLiuMing LED lighting, we still feel blurred vision? Specific reason to have the following two points:

1. Our eyes to long-term natural light, and at present almost all the LED lighting products are monochromatic radiations. Relative to our eyes for, whether it is still warm color is white, monochromatic radiations are not good thing always reduction of color itself.

2. LED lamp produce monochromatic light, although the lumen is bigger, but as far away. So we in the LED lights have such a feeling, from light near the special dazzling; Far and away from light feeling brightness enough; In contrast, the effect of warm color a little bit better.

The high power LED light source can reduce the heat produced in

When 3528 light source birth suspension, 5050 before the position of the light source is starting to waver. Many friends in the earlier "is 3528 light source, the reason is the 3528... the narrow, sales up no 5050 so easy. And now, those who complain about 3528 light source friends in the appropriate time make a barrel of gold. Now more than 70% of the indoor lighting products are used 3528 light source. Its actually use 3528 light source though can be the cost savings, but at the same time also can bring some technical problems.

In general case, a 1 W light source a hour to produce about 3000 joule heat; And two 0.5 W light source of calories an hour in about 3500 joule heat. So just for saving energy, the latter the light of low efficiency. With a 5 W ball steep light, for example, if you use single 1 W light source, the pure light source of calories an hour in about 15 K joule; And the 0.5 W of the source of the light, the light source of calories an hour in about 16.5 K joule.

Thereafter, the same power, using 3528 light source than with 5050 in more light source heat, that is normally, the lamps and lanterns of same power, high power than small power source of light source the light rate. At the same time in the same power under the premise of light source, with the increase in the number of light source, the yield of aluminum plate heat also can increase accordingly.

In addition, 5630 this LED encapsulation body, also has international manufacturers in use, but the technology to the threshold of the higher, is currently has the technical force of the manufacturers to gain advantage.

As is known to all, the light source heat and chip in with absolute relationship. So in the control of the heat lamps in, in addition to consider to choose the high quality chip packages of the source of the light, even as far as possible much consider the number of bead light. And now a lot of manufacturers to cater to is the market, have to use the small power source of light to control the cost to increase market competitiveness. Of course in high power source heat compared with little power is no edge, but with high power source of light failure this weakness be solved step by step and price decline, later in the market application should have good performance.

Light sensor problem can use light mix build or chimney processing

Currently LED by monochromatic light show color index is low this problem, many companies have started developed a wide range of color temperature to mix the lamps and lanterns. Of course such effect may cause light or uneven phenomenon, this to the chimney and lens set the new request. Such as using high light transmittance grind arenaceous lens is pervious to light quality good milky white chimney.
