LED lighting industry has great potential economic and social benefits, so that countries around the world have developed plans and support policies to promote the rapid development of LED lighting industry and market. China's "electronic information industry restructuring and revitalization plan" clearly put forward to vigorously develop energy-saving and environmental protection LED lighting products, the Ministry of science and technology has officially launched the "Ten City million" LED lighting applications. But at present, the high cost of LED lighting, while facing the lack of standards, heat dissipation performance to be improved, power supply needs to be redesigned and a series of problems. To this end, this newspaper invited experts on how to promote healthy and healthy development of China's LED lighting industry recommendations.

Objective analysis to grasp the key points of LED lighting development

To have a comprehensive understanding of the connotation of LED lighting, to objectively analyze the actual technical level of China's LED field, to a reasonable layout, steadily promote the development of LED lighting and priorities.

In the field of technology, we should increase the support for the research and development of materials, especially for high-power lighting technology to give priority to the development of chips.

In the field of industry, we should pay attention to display the application of products, landscape lighting, public lighting and other markets.

At present, LED street lamps have many technical problems, such as heat, light, energy efficiency and reliability of the system has not yet been resolved and withdraw at the end of the cost, the price is too high, not promote the use of large area, should do the demonstration project in secondary roads. At present, the support of the local government is very large, blindly launched, but also support the development of LED street lamps in the region, many companies do not understand the performance of LED street lamps, blind investment, will cause a lot of waste. I think the next two years, LED light efficiency of 120lm/w ~ 130lm/w, the basic technical problems solved, the cost has dropped significantly, then large-scale promotion of LED street lamp is more appropriate.

The Ministry of science and Technology launched the "ten city lights" semiconductor lighting engineering, a huge role in promoting the development of the LED industry, in the specific implementation process is to pay attention to several issues: first, LED lights as a new thing to advance step by step, the scope of application must be compatible with the existing technology, can from the community, support with the road, after the first easy to gradually promote the main roads, tunnels and other applications. Secondly, to develop the appropriate technical specifications and test methods, the panel should be broad, covering the lighting, semiconductor, electronics and other fields of expertise. Again the best advance two steps, the first step demonstration period: outstanding product quality, in the implementation of strict quality control, encourage technological innovation, avoid price bidding, should be based on the performance index, product localization rate and the quality of enterprises as an important consideration; the second step market competition period: through several rounds of demonstration and application the formulation of LED lamps specification or standard more perfect, and the LED lamp manufacturing enterprises to set up technical barriers and higher quality guarantee threshold, shall be in accordance with the market mechanism of price competition.

In promoting the application of LED lights, special attention should be paid to: because of the luminous flux and the cost of LED is almost a linear relationship, and the effect of light there is great room for improvement, LED is not suitable for application in the high light flux. The application of LED street lamp should be focused on the places such as sub roads, sidewalks, squares and gardens. General LED street light power in the best 150 watts or less, so that both in the cost, or in the heat treatment of the problem will not have too much obstacle. When the time is ripe, and then to the large area of main road and high pole lamp applications. San Francisco, Losangeles and other regions are also promoting LED street lights, their approach is more secure. Do first test, test and field evaluation, and then modify the rapid establishment of standards, the negative impact of this will avoid detours and avoid the blindness. Once the pilot is successful, you can quickly carry out large-scale promotion. These practices are worth learning from domestic counterparts.

We must pay attention to Quweicunzhen, beware of fake and shoddy, must be certified by the state data and report to the third party testing institutions as the basis for the selection of products, patient, don't break the reputation of LED lighting.

Ten City million light, the main push the street lamp, starting from the high risk of outdoor lighting is inappropriate, involving the lumen efficiency, heat dissipation, optical problems, life issues, which are required to improve. Due to the total cost of chip devices up to 50%, for the large size of the chip or device is monopolized by foreign brands, the domestic epitaxial chip and packaging industry in the "city of ten thousand" project to benefit from limited ten.
