Five common problems in LED lighting industry

LED lights are used in the construction and lighting effects of the Shanghai World Expo and the Guangzhou Asian Games. Many of the LED lights that have been replaced in the ten-city plan have been removed, and the light has been seriously degraded. It won't take long for the lights to become dim. Here we summarize five common problems in LED lighting industry: five common problems in LED lighting industry, local protectionism in supporting policies some local governments have issued policies to cultivate local LED lighting enterprises, giving priority to local municipal landscape lighting and traffic lighting, this makes LED lighting downstream enterprises have to focus on participating in the bidding of government projects. In addition, LED lighting standards have not yet been formulated in China, and application standards vary from place to place, resulting in great resistance when enterprises explore markets across regions and limiting the overall development of LED lighting industry. Lack of brand awareness has LED to a large number of enterprises, mixed with good and evil people, uneven products and no independent brands, resulting in the theft of some patents and frequent infringement incidents. The civil function is in urgent need of policy support. As the price of LED lighting lamps is more expensive than that of traditional sodium lamps, and the one-time investment is relatively large, the local government does not dare to invest boldly, as a result, the popularization and application speed of LED lighting lamps in China lags far behind that of Western countries. At present, lighting associations in various provinces and cities are responding to government policies, such as Shanghai Lighting Association, Guangzhou Lighting Association, etc. Lamps in various provinces and cities are hot sales spots, such as Shanghai Lighting City, Zhongshan lighting City, etc. At the same time, the vast majority of LED lighting in our country is still used in public facilities, and the daily function of LED lighting still needs the support of relevant policies. Many bottlenecks still restrict the development of LED industry and cannot be popularized like energy-saving lamps. But what is worth celebrating is that in recent years, more and more LED enterprises have focused on the market, looking for channels suitable for their own products and paying attention to the different advantages of market competition; Gradually strengthen the promotion and cultivation of their own brands; Pay attention to the overall regional environment and begin to standardize the market competition order. Technology and Equipment bottleneck. In terms of LED substrate material technology and epitaxial wafer production equipment, there is an obvious bottleneck in the domestic LED lighting industry. Independent innovation and patents in the LED field of Chinese enterprises are mainly concentrated in the packaging stage, while in the key aspects of white light, heat balance of high-power LED lamps, durable and efficient fluorescent powder, etc, technology patents have been monopolized by companies in Europe, the United States, and Japan. There is still a big gap between the brightness, luminous efficiency, antistatic ability, leakage resistance and quality control level of domestic LED lighting products and international products. Lack of product pricing power domestic LED enterprises are small in scale and scattered in industrial resources. Core chips, especially high-power LED chips, mainly rely on imports from abroad. A single small and medium-sized manufacturer can only import expensive chips from abroad, resulting in low bargaining power and high costs.
