General situation of LED industry

The development of the domestic LED industry started from the 70's of last century. Mainly made up of materials like GaP and GaAlAs, the LED research and industrialization has begun. Many colleges and institutes got into the study of the High Bright LED based on the 4-element series based on InGaAlp and GaN system from the 90's. Wha's more, a lot of powerful enterprises have been investing in High Bright and White LED industry in recent years, thus promoting the industry development rapidly to a yearly turnout of 10 billion pieces of High Bright LED chips and 30 billion pieces of packaging. As it is shown in the figure, the growth rate of High Bright chips exceeds 100% while that of the device exceeds 50%. According to the statistics and evaluation made by the industry association, excluding the overseas investment enterprises, there are more than 1000 domestic companies based on LED industry. Except for the epitaxial equipments and part of raw materials, domestic companies have a strong matching capability of major raw materials, manufacturing equipments testing instruments and key matching parts of led spot light products, such as phosphor, LED driving IC, application lamps, lead frames and matching tooling. A complete industry chain has been formed.

So far there are more than 100 foreign invested enterprises that are related to LED. With the further implementation of the government policy of reform and open-to-the-world, continuous improvement of investment environment as well as its increasing potential wholesale led lights market, more and more investment from all over the world will be attracted to mainland China, especially for that from Taiwan, Korea and Japan, possibility of large scale investment is even more. It is most likely that Mainland China will become one of the important bases for the world LED industry in the near future

Technology on LED packaging and industrial trends

The capability on LED packaging in China is very strong, according to preliminary investigation, there are more than 100 enterprises who have ability in doing LED packaging with large scale while about 500 – 600 enterprises with small scale. The total capability of packaging is 30 billion pieces per year. The export quantity of processed LED is as many as 10 billion pieces per year. It is estimated that the LED packaging capability in China (including foreign invested enterprises) could be as high as 50 billion pieces per year. These enterprises are: Xiamen Hualian Electronics, Foshan Nation Star, Jiangsu Wensum, Cotco Holdings (Huizhou), Shenzhen Quantum, Ningbo Hepo, Jiangxi Lianchuang, Tianjin Tianxing, Langfang Golden Valley, Shenzhen Leman. They can package various LED products like: LED display of different outline dimension, single LED, complex LED, pixel LED, digital display, back light source, SMD-LED, miniature LED, matrix display, special display, white LED, power LED and power LED module, etc. The match capability of the material for packaging and matched parts is good, industrial chain has been created. What should be stressed here is that about a dozen of enterprises in China are able to provide phosphor to package the white LED. In recent years, better result has been achieved in increasing phosphor light excitated efficiency and ability in anti-light attenuation.

Regarding the packaging of white light and power LED, better equipped companies had devoted great effort to its process and product research and development. They are: No. 13 Institute of China National Electronic Group, Xiamen Hualian Electronics, Foshan Nation Star, Shenzhen Quantum, Cotco Holdings (Huizhou), main technical problems in the power LED packaging have been solved gradually in the process R & D, such as increasing lighting efficiency in packaging and base heat sink performance, reducing heat resistance, raising anti-light attenuation capability and operation life. At the same time, major technical problems have been solved in the packaging process for white led lights china like : the control on the lighting uniformity, consistency, the color temperature and color display, anti light attenuation ability, reliability and white light parameter testing, etc. At present, white light and power LED devices could be lot packaged, the light efficiency of 1W white LED can reach 50~60lm/w, heat resistance is 10k/w.
