What technical difficulties need to be solved for LED solar street lights

Nowadays, with the rise of some emerging industries, people's demand for night travel is increasing, so road lighting systems will appear. The road lighting system first appeared as a white flag lamp, but with the continuous development of science and technology in our country, the standard of living has been continuously improved, and people have made new improvements to the road lighting situation. In addition to its own advantages, what other technical difficulties need to be improved. 1. Optical design From the perspective of light distribution of led street lamps, the backlight of this solar street lamp generally includes primary light distribution, secondary light distribution and tertiary formula. Under normal circumstances, street lamps can satisfy people's road lighting when they pass the secondary light distribution. There are some other requirements for uniform astigmatism, so there is no need to perform the third optical design. But no matter what kind of formula is used, it is impossible to be reasonable and scientific. To some extent, there will always be some problems such as low optical efficiency, or too bright light, insufficient illumination, etc. How should we improve ? Some more mature solutions are still needed. 2. The heat dissipation problem The heat dissipation problem of the LED lamp can directly affect the actual luminous efficiency and its life. As a light-emitting device, it only has 15% to 25% of the electric energy in the daily work process. It can be converted into light energy, and the rest is basically converted into heat energy. As the illumination time is longer, the temperature of the led solar street lamp will gradually increase, which will lead to a sharp drop in light efficiency. 3. Design of driving power supply At present, the power supply of led street lights is almost always powered by a power supply. From its structure, it is generally an offline switching power supply. Because the working environment of led lights is very harsh, the design of the driving power supply The requirements of each link are very demanding. According to the current level of our country, not only must pay special attention to its reliability, but also meet other performance requirements such as electric shock and waterproofing in the design of driving power supply for led street lights. The most important thing is that security threats must be minimized. Led solar street light is a new generation of green energy. It has very strong advantages for road lighting and traditional street lights. Although there are some problems that have not been solved yet, overall it is a very good resource that can be used. Although there is a long way to go, we must persist.
