The effect of increasing the heat dissipation area of solar street lamps

by:Road Smart     2020-04-07
The solar road lamp has poor heat dissipation, which will accelerate the loss of LED lamp life. The second is to affect the lighting effect. Long-term poor heat dissipation will lead to increased LED light attenuation; LED solar street lamps need to dissipate heat, and the lamp body should adopt all-aluminum lampshade. Solar street lamps with higher power will also adopt aluminum lampholders, and depict the shape with faster heat dissipation effect to increase the heat dissipation area. To dissipate heat, solar street lamps can also be adjusted by the controller to reduce LED heating, which can not only save energy, but also reduce heat. Solar street lamps can improve their lighting brightness by obtaining good heat dissipation, long service life and resistance to rainy days. Some street lamps are installed with radiators to dissipate heat, but the weight is too large, and the risk is in the case of frequent accidents, typhoons, earthquakes, etc. Needle-like heat dissipation: The heat dissipation efficiency of the needle-like heat sink is greatly improved compared with the traditional sheet-like heat sink, so that the junction temperature of the LED is more than 15 ℃ lower than that of the ordinary heat sink. (1) In the field of solar power generation, solar street lamps play an important role. They adopt the form of 'photovoltaic energy storage' and are typical independent solar power generation systems. During the day, the sun is enough to generate electricity from photovoltaic cells, charge the battery, discharge at night, and power the street lamp. A typical led ceiling lamp system includes a battery--Battery--Street lamps and controllers. In actual use, if there is no reasonable control of the battery, the charging method is not suitable, overcharge and overdischarge will affect the battery life. In order to reduce the protection cost, the battery is charged reasonably in the most effective way. (2) It is recommended to use LED lamp soft ceramic heat dissipation paint for external protection of lamps. This kind of spraying soft ceramic heat dissipation paint can be directly sprayed on the outside of LED lamps, which is easy to operate and can adapt to heat dissipation structures of various shapes. LED street lamps, landscape lamps, or LED advertising billboards used outdoors will also face wind and rain, acid rain and bird droppings, air dust and black smoke emission hELlip; And so on the acid-base infringement. Soft ceramic heat dissipation paint has certain acid and alkali resistance characteristics, which can effectively protect the appearance of LED outdoor lamps from erosion. (3) The external protection of LED lamps is recommended to use LED lamps soft ceramic heat dissipation paint. This kind of spraying soft ceramic heat dissipation paint can be directly sprayed on the outside of LED lamps, which is easy to operate and can adapt to heat dissipation structures of various shapes. Landscape lights, or LED advertising billboards, will also face wind and rain, acid rain, bird droppings, air dust, black smoke emissions hELlip; And so on the acid-base infringement. (4) Too low temperature will affect the charging and discharging of the solar street lamp battery, making it fail to meet the design standard. If you want to make Taiyi solar street lamp guarantee a long rainy days, increase the battery capacity and improve the conversion rate of the battery panel, it is a technical method that can be used.
