LED lighting products production has the following

(1) the luminous LED the principle, is electronic through a layer of semiconductor material, stimulate the semiconductor material energy into light energy. However, in light of the semiconductor ability is very weak, so will stack up many single layer materials, pressed into similar thousand layer cake that composite material, it is a 'extension pieces'.

So, LED the luminous efficiency in the decision in the same thickness, how much can pressed into the layer. In the thin material, can multiply layer, the more luminous efficiency is higher. Now general every layer thickness is only 2-20 microns, it also determines the extension of production is the whole production process LED the most difficult part.

(2) the cutting-LED core: tungsten materials drawn from equivalent filament, different is, after cutting the denotation of square shape.

Due to the special structure of the extension, want to complete intact start cutting light core, very difficult. Not only need to vacuum environment, but also professional cutting machine. Currently the world, only two manufacturers the cutting machine.

(3) in the core LED chips: chip to LED, as the lamp holder in the light bulb, is part of the power supply. 'Chip' is to achieve the ideal effect very important LED equipment, because of the requirements of the current LED is very high.

(4) the encapsulation LED chips into lights: will be LED chip packages lights, as the filament lamp holder and chimney to make the light bulb. Chimney is the basis and different shape needed, but packaging technology decided the service life of the lights.

(5) lighting applications: like using the incandescent light bulb, according to different function and need, assembly into different LED products.

LED lighting to it, three steps before the extension of disc, cutting and chip is ahead and step 4 encapsulation is middle reaches, the step 5 is the application of the downstream. These problems we need to use more energy to break through.

Due to the special structure of the extension, want to complete intact start cutting light core, very difficult. Not only need to vacuum environment, but also professional cutting machine. Currently the world, only two manufacturers the cutting machine.
