Tell the Increase in the Area of the Chip to Increase the Amount of Light Emitting

Although the area of the LED chip is large -scale, so as to obtain a much higher brightness, but due to the excessive area, there will also be a counterproductive phenomenon in the application process and results. Therefore, in response to this problem, some LED operators improved on the surface of the chip according to the improvement of the electrode structure and the structure of the crystal. For example, in the part of the white light LED crystal packaging, because the luminous layer is close to the encapsulation, the electrode will not be covered when the light of the luminous layer is spread out, but the disadvantage is that the heat generated is not easy to dissipate. It is not after the surface improvement of the chip, coupled with the increase in the area of the chip, it can definitely increase the brightness quickly, because when the light spreads outward from the inside of the chip, these improved parts in the chip cannot be reflected, so it will be a little bit a little on the light extraction. Restrictions, according to calculations, the size of the LED chip with the best use of light efficiency is around 7mm2. Compared with the use of several small -area LED chips to quickly improve the lighting efficiency and a large area of LED chips, the small -power LED chip is encapsulated into the same module. LED packaging together. Some doubts caused by this method of patch LED, because multiple LEDs are encapsulated on the same module, and some insulating materials must be placed to avoid short circuit between LED chips. Many costs. Patch LED, the price of first -class quality and competitiveness is your best choice! Welcome to inquire
