1. How to ensure the quality of street lamps
LED street light is a system consisting of multiple parts, including light source, power supply, heat dissipation module, and mechanical structure. Each item affects the performance of the entire lamp, and a problem with one part can cause fatal damage to the street light. In the process of investigating the enterprise, the author found that nearly half of the enterprises use their own power supply. Is the LED street light power supply easy to design? Obviously the answer is no, in the case of DC high current, the voltage is constant. Flow is not easy.
Foreign LED street lamp suppliers have deep research in heat dissipation and structure, mastering many patented technologies, and domestic manufacturers are plagiarizing the wind. Many street lamps have a sense of deja vu in terms of structural design and heat dissipation. They are truly innovative. many. At present, the optical design of LED street lamps is a mature technology. On the contrary, structure and heat dissipation are the challenges faced by most manufacturers. There is a danger of latent design.
2. Local companies should not give priority
According to the survey of the High-tech LED Industry Research Center, most or all of the enterprises participating in the demonstration projects are local enterprises. What is the purpose of local governments participating in the ten cities? Energy conservation and emission reduction still support the development of local semiconductor lighting companies? If it is the former, quality and energy conservation are the key points. If it is the latter, contracting projects by local companies is understandable.
From the national level, we want to use the expansion of the market to support some excellent enterprises. No matter which province and which city the company comes from, it is not a group of enterprises distributed evenly by region. But the purpose of the local government is obviously different from the starting point of the Ministry of Science and Technology. The locals will consider that our money has gone to the pockets of other provinces and cities, and it is worthwhile to contribute GDP to others.
Another drawback of reusing local businesses is the inability to guarantee quality. LED street lights are a technology that has only started in recent years, and quite a few companies have not produced LED street lights for a long time. There is not enough time to verify the reliability of the LED street lights that you have designed, which poses a huge risk to subsequent maintenance.
