The innovation of LED industry development

The disadvantages of the current semiconductor lighting mainly in the following areas:

1, high power LED light effect is low

The formation of more than 3 watts of high-power light-emitting diode light-emitting efficiency is low, less than the luminous efficiency of more than 100 lumens per watt high intensity gas discharge lamp, also less than 60 lumens per watt or more of the rare earth three primary fluorescent lamp. Said semiconductor lighting energy saving, energy saving, in fact true only in small power range, with current technology using high-power semiconductor light source lighting and efficient light source compared to existing and will not save much energy, but the initial investment cost is very high.

2, high power LED prices higher. At present, the market price of 1 watts of high-power white light LED is about ten times more than the traditional light source price.

3, light efficiency is low, the input of electrical energy into a large number of heat. The luminous tube is cold light only refers to the luminous body itself is not hot, but the resistance heat generated in a semiconductor material on large current will produce led to higher temperature, and light emitting diodes made of semiconductor materials is not high temperature, overheating will cause the service life greatly reduced, with the increase of radiators the size of the lamp, the semiconductor light source with small volume and light weight advantages disappear.

4, the light spot, because of the white LED manufacturing process on its own defects coupled with the reflector cup or lens with the error, easy to cause yellow circle problem.

In recent years, the rapid development of LED industry, but according to the above analysis we can see that on the luminous efficiency and the price level in the semiconductor light source in the short term really entered the field of general lighting to replace the traditional light source is not easy. To solve these problems, it is necessary to improve the luminous efficiency and reduce the production cost. However, in the current technical conditions, the development of semiconductor lighting industry should actively develop the advantage direction, promote the progress of technology and production process, so that the semiconductor lighting era to come early. In the final analysis, the deep development of any industry can not be separated from the promotion of technical force, LED technology innovation has become the inevitable development of LED industry!
