LEDinside recently visited Mr. Tang Guoqing, general manager of China Market Development of LED manufacturer CREE. Mr. Tang is currently the legal representative of Shanghai Optoelectronics Industry Association and the director of the Semiconductor Lighting Committee of China Lighting Association. Therefore, whether it is the perspective of the lighting association or the representative of CREE in China, General Manager Tang has a very important reference value for the lighting industry and LED market in China.
China LED market outlook: choose the lights, do the lights
Tang Guoqing said that China's lighting sector development has a major focus on policies promoted by the state. The release of these policies will greatly help the development of semiconductor lighting and LED lighting market. Including the research and development and promotion of the industry, there are specific policies to assist. At the same time, the government may support the semiconductor lighting industry as it supports the development of the semiconductor IC industry. On the specific front, according to the Chinese Minister of Science and Technology, China has two attitudes to encourage the green energy industry. One of the ten cities is an electric car that encourages environmental protection and energy conservation. The second is the ten cities and promotes Encourage the construction of demonstration projects for LED street lights.
As far as LED street lamps are concerned, it is not only a slap in the face, but there are six cities in Guangdong Province that are also carrying out LED streetlight projects. From a macro perspective, it is a great boost for semiconductor lighting fixtures. The road lighting is not just LED street lights, but also tunnel lighting. There is a lot of room for development in this area.
However, in the aforementioned lighting category, Tang Guoqing believes that the choice of LED light source is a big challenge. He supports the use of LED light sources, but be careful not to start with a bet, you should choose a good light and a good light. He believes that most of the manufacturers at this stage are picking the hardest LED streetlights. Some manufacturers are not as good as the technology, and the performance of LED street lights is not as expected. It also deepens the doubts about LED street lights. This is because LEDs are used in road lighting. In fact, there are many technical problems to be faced and overcome, including appearance, materials, LED chips, and packaging to make LED lighting fixtures. This series has high-tech technical components. inside. Rather than what many people thought before, the front-end technology is high in content, and the latter part is because it is part of the lighting fixture, so the technical content is low, which is wrong. In fact, every stage must be properly considered, LED lamps will have good efficiency.
Not just road lighting, but also on indoor lighting.
In recent meetings, Tang Guoqing also called for besides outdoor lighting and road lighting, and began to bet on the power of indoor lighting. This is because indoor lighting is relatively inferior to outdoor lighting. After all, it is not so hot, and there is no need to deal with the problem of hot sun and rain. But it can't be ignored, because there are still certain problems to be solved in order to do indoor lighting.
In the current development of the Chinese market, the development of road lighting supported by the government is more obvious. Several cities have already been launched. For example, Dalian, Hangzhou, Shenzhen, Dongguan, Shandong and other places are not dozens of LED street lights. Instead, thousands of lamps, LEDs as the main lighting source, the market has moved.
Tang Guoqing said that although the number of LED street lights installed in the Chinese market is large, not every one is very successful. The main factor is the technical problem mentioned above. Not all LED packages are suitable for the light source of LED street lamps. It is not the level of LEDs that can be equipped with LEDs. If you do not choose carefully, you can make them. Street lights are not good enough. High-efficiency LEDs are still one of the keys to LED lighting.
