Interpret LED Lighting Technology From the Chip Level

Today, with the continuous development of LED lighting technology and the increasing importance to the energy crisis in society, the LED lighting industry has ushered in a comprehensive explosion period, attracting many funds and enterprises. From the perspective of the development of LED lighting technology, from three aspects, one is the chip level, the other is the packaging level, and the other is the application level. The chip level mainly focuses on the technology of LED; the package level is mainly to convert LED chips into lamps or light sources that can be used to light; Development and use, the development and improvement of environmental lighting quality evaluation technology. At the chip level, the driving force for the development of LED chip technology is always based on the pursuit of high lighting efficiency. Installation technology is one of the main technologies that currently obtain high -efficiency high -power LED chips. Sapphire in the substrate material and the laser lining technique (LLO) and new keyhered technology of the vertical structure supporting vertical structures will still be. Dominate. However, in the near future, the metal semiconductor structure is adopted to improve Ohm contact, improve the quality of the crystal, improve the electronic migration rate and electrical injection efficiency. Efficiency, the total efficiency of white light LED can reach 52%. With the improvement of LED light effects, on the one hand, the chip is getting smaller and smaller, and the number of chips that can be cut on a certain size is more and more, thereby reducing the cost of a single chip. On the other hand If it is now 3W, it will develop in 5W and 10W in the future. This can reduce the number of chips and reduce the cost of the application system on the cost of lighting requirements. In short, the inverted method, high voltage, and silicon base nitride will still be the development direction of the semiconductor lighting chip.
