Responsible for the long-term LED home lighting technology prices need to improve
In the industry, LEDs are being developed and produced by countless entrepreneurs, and they have occupied a very important market position in engineering and outdoor lighting, but when refined to home lighting, this market is still a potential stock. How to bring LED light sources into the homes of ordinary people is a headache for countless businesses. Now let's explore the future direction of LED home lighting. LED light source technology has been formed in the domestic LED lighting industry distribution is relatively concentrated, has initially formed the Pearl River Delta, Yangtze River Delta, Southeast Asia, Beijing and Dalian and other northern regions, each region has basically formed a relatively complete industrial chain, Dalian The four regions of Shenzhen, Xiamen and Nanchang already have mature production bases for LEDs. On the one hand, due to the lack of sufficient understanding of LED lighting in society, on the other hand, LED lighting products have been difficult to achieve as high as traditional lighting products. On March 20 this year, the 2012 fiscal subsidy promotion project for semiconductor lighting products organized by the Ministry of Finance, the National Development and Reform Commission, and the Ministry of Science and Technology conducted a domestic public bidding in Beijing. Nearly 300 bidders from 110 companies across the country participated in the bidding activities. LED products including LED downlights for indoor lighting, reflective self-ballasted LED lights, and LED street lights and LED tunnel lights for outdoor lighting are listed as tender products. The National Development and Reform Commission has made it clear that in 2012 the Chinese government will spend 40 billion yuan on LED streetlight purchases and 30 financial subsidies for LED streetlight users. In general, China's LED industry pattern has a high degree of industrialization in the south. The Pearl River Delta and the Yangtze River Delta are the most concentrated areas of the domestic LED lighting industry. The upstream, middle and lower reaches of the industrial chain are relatively complete, and more than 80 related enterprises across the country are concentrated. The north relies on many universities and research institutions, and the product research and development strength is relatively strong. Technology and price are still difficult to solve. Although there are a small number of home lighting companies in Zhongshan Guzhen market, LEDs are used as light sources, but they have always encountered great barriers and are still in an imperfect period. Encountered technical and equipment bottlenecks. In the technology of LED substrate materials and epitaxial wafer production equipment, the domestic LED lighting industry has obvious bottlenecks. The independent innovation and patents in the LED field of China's enterprises are mainly concentrated in the packaging stage. In the most critical white light, high-power LED lamp thermal balance problem, long-lasting and efficient phosphor, etc., the technology patent has been used by European, American and Japanese companies. monopoly. The brightness, heat dissipation, luminous efficiency and uniformity, antistatic ability, anti-leakage capability and quality control level of domestic LED lighting products are still far from the international products. LEDs lack product pricing rights. Domestic LED companies are small in scale and industrial resources are scattered. Core chips, especially high-power LED chips, mainly rely on imports from abroad. A single small and medium-sized manufacturer can only import high-priced chips from abroad, resulting in a low bargaining power, which keeps costs high. For a single family, the energy-saving performance of LED lamps is not obvious, and it does not save much money. Moreover, LED lamps are three times more expensive than ordinary lamps, and it is also a problem for ordinary people to bear. Lack of brand awareness LED companies have a large number of companies, mixed products, products are not in the same order, there is no independent brand, resulting in some patents being stolen, infringements have occurred frequently. LED home road has a long way to go According to a report released by the relevant departments of Guangdong Province, LED companies in the United States, Japan and Europe have more than 80 LED chip core technology patents, while domestic similar enterprises have less than 10 similar patents. For a long time, LED upstream epitaxial wafer and chip market core basic technology, by several foreign industry giants such as Nichia, Toyota Synthetic, Cree, Osram and other monopoly, occupying the output value of the entire industrial chain of 70 or so, which also makes China's LED industry chain The structure is very unreasonable. The author believes that although incandescent lamps began to delist to give LEDs a market, bottlenecks such as acceptance prices still restrict the popularity of LED home lighting. Of course, with the continued development of LED technology and the continuous improvement of product quality, stepping into home lighting is still the trend of the times. China's LED lighting industry can not be blindly optimistic, the road of home lighting has a long way to go.
