The “Twelfth Five-Year Plan†will be a key period for China's semiconductor lighting technology innovation and industrial development, especially in the representative core area of ​​“chipâ€, further realizing independent innovation and initially establishing several internationally competitive nations. The brand will become the only way for China's LED industry to become bigger and stronger, and to cope with the fierce international competition in the future. It has also become the most urgent historical mission of China's LED chip companies.
At present, China's LED industry is developing rapidly, and the upstream chip field with high core technology and capital threshold is still the soft underbelly restricting the development of the whole industry. "China's 80% high-end chips rely on imports" is the bottleneck of industrial development. At the top of the pyramid of high-power and high-brightness lighting, there are only a few companies in the domestic market, such as Wuhan Diyuan, American Cree and Taiwan Jingyuan. To be a world-class Chinese "core", this may be a big dream for most companies.
Only China's LED high-power chip companies are really strong, can drive the real rise of China's LED lighting, the upstream chip field is the most discourse and the most profitable part of the industry chain. If China has been missing high-end LED chips in the future. Even if the government invests ten times the capital and energy in the demonstration project, it is more conducive to foreign giants to obtain excess profits in China. At the same time, according to the laws of high-tech industries, the standards of the entire industry can only be implemented in accordance with foreign standards. And if the national power of the organization will focus on the high-power technology that has begun to take the international standard level, and further smelt it, and truly turn it into a vanguard force to occupy the commanding heights of the industry, then its detonated productivity "nuclear change" will It is expected to completely break through the blockade of foreign companies in the upstream, and the development of the upstream high-power enterprises will make the industry "all live", driving the development of the entire industry and even fundamentally rewriting the pattern of China's LED industry.
Today, the era of LED lighting is coming, high power has more important strategic significance for supporting the ultimate "lighting world", and it has undoubtedly become the "hard truth" for the Chinese army to take the opportunity to enter the international lighting market. HVLED is actually the traditional DCLED. The COB package structure is directly implemented at the chip level, which reduces complicated operating procedures such as solid crystal bonding and bonding of the application end package, and directly brings down the manufacturing cost of the application end.
Compared with traditional DCLED, HVLED can be directly applied to the DC high-voltage driving lighting market, simplifying the design of the driving circuit, reducing the use of components, lowering the power loss of the driving circuit, higher reliability of the device, and further miniaturization of the structure. The application cost is greatly reduced; and because it is a small current driven power chip, it is easy to integrate with the red LED chip for warm white light, and the conversion efficiency of this structure is higher than that of the conventional DCLED direct excitation phosphor, thereby reducing the size. LED is used in the gap between warm white light and cool white light.
