Weifang is one of the national semiconductor lighting industrialization bases. Nearly 100,000 street lamps used for urban road lighting in the city have all adopted LED products, which is unique in the country and rare in the world. This is the pride of Weifang and the pride of China. However, the chips used in nearly 100,000 street lamps are all foreign products, and there are no domestic chips. This is the sorrow of Weifang and the sorrow of China. The Weifang Municipal Government's bold attempt this time is also a positive and strong support for domestic chips, and is a powerful measure to promote the localization of high-power lighting chips.
As the globally recognized fourth-generation green lighting source, power lighting has attracted worldwide attention, and developed countries around the world are vigorously developing the lighting industry. Our country not only increases support for the LED industry through financial subsidies and attracting talents, but also guides them through administrative measures and policies. This year, the National Development and Reform Commission issued the "China Roadmap for Phased Elimination of Incandescent Lamps (Draft for Comment)". According to the plan, by 2016, China will completely eliminate the use of ordinary incandescent lamps.
The high ground for occupying power lighting has important strategic significance in terms of energy conservation, environmental protection, and occupation of the international market, maintaining leading technology, and promoting the development of the national economy.
China's LED industry started late, and it lags behind Europe, the United States, Japan and other developed countries in technology. The scale of the industry is smaller than that of South Korea, Taiwan and other countries. It is contrary to many obstacles such as patents, technology and talents. The products are in performance and quality. In the long-term, there is no big improvement, and it is difficult to enter the high-end application field, especially the urban road lighting, which is an iconic field showing the level of high-power white light lighting products. Therefore, the first breakthrough of Inspur Huaguang in this field has its profound practical significance and historical significance.
In recent years, Inspur Huaguang has increased its investment in research and development of blue and white optical power chips, and established a special scientific research group. It has made many technological breakthroughs in power blue-and-white light products. The brightness of the tile-level chip has exceeded 350mW, and the brightness of white light can reach more than 130lm. The medium and large size (30mil) high-power chip was successfully developed, the brightness reached more than 300mW, the white light reached more than 90lm, the red light reverse polarity power chip successfully entered the lighting market, the brightness was above 60lm/W, combined with the white light product to form a low color temperature. The high-quality high-power lighting products of Gao Xianzhi have successfully replaced the original imported reverse polarity red light chips and become partners with many domestic power lighting companies.
With its strong technical strength and long-term technology accumulation, Inspur Huaguang has obtained more than 160 various technical achievements, of which more than 40 achievements have reached the domestic leading level and international advanced level; 90 patent applications, including 69 invention patents. It has authorized 37 projects; it has undertaken 25 government projects including the “863†plan of the Ministry of Science and Technology, the Ministry of Industry and Information Technology, and the National Development and Reform Commission. The adoption of this high-power chip in urban road lighting is the result of the long-term accumulation of its technical strength. 
Inspur Huaguang Optoelectronics Co., Ltd. (hereinafter referred to as "Inspur Huaguang") in the field of road lighting in Liangjian City, took the lead in realizing the breakthrough in the background of foreign manufacturers' unified road lighting chips. In September 2011, some of the street lamps that were built 20 kilometers away from the new main road in the northern section of Beihai Road in Weifang City used LED chips independently produced by Inspur Huaguang.
