Why do LED Solar Street Lights need to Dissipate Heat?

LED solar street light is currently a mature lighting solution for municipal lighting projects. At present, some rural areas have begun to gradually install solar street lights. As led solar powered street lights become more and more widely used, problems will gradually increase during use. In particular, the heat dissipation of led solar street lamps is a major concern of users. Most of the current solar street lights use LEDs as the light source, but the LED lamps emit light and heat when the current passes. In general, the main heat source is a large amount of current when the current passes through the LED in the reverse direction.

If the LED solar street light does not dissipate well, it will accelerate the lifespan of the LED lamp, and it will affect the lighting effect. The long-term poor heat dissipation will increase the LED light decay. Third, the accumulation of fever will cause the aging of the lamp holder and other equipment, which will affect the use. Therefore, the heat dissipation of led solar powered street lights is significant. High-power solar street lights will also use aluminum lamp holders, and depict a shape with a better heat dissipation effect, and increase the heat dissipation area. For led solar street lamps to dissipate heat, the controller can also be adjusted to reduce LED heating. If the solar street lamp fan has a good thermal design, it can increase its lighting brightness, prolong its service life and the number of rainy days in continuous work.

Heat dissipation design is a very important part in the design and production process of solar street lights, and it is also one of the technical bottlenecks restricting its wide use. The quality of the heat dissipation design will directly affect the service life of led solar street lights. At present, there are three commonly used heat dissipation methods for LED solar street lamps.

1. Heat conduction plate heat dissipation: it is to dissipate the heat generated by the solar led street lamp to a conductor, and the heat is exported out of the lamp cap through the meson, thereby dissipating the heat. The conductor is generally a 5mm thick copper plate, which is actually a temperature equalizing plate, which equalizes the temperature of the heat source and increases the heat dissipation area;

2. Heat sink to dissipate heat: some street lamps are equipped with heat sinks to dissipate heat, but the weight is too large and the risk increases. Accidents are prone to occur in case of typhoons, earthquakes, etc.;

3. Needle-shaped heat dissipation: The heat dissipation efficiency of the needle-shaped radiator is greatly improved than that of the traditional fin-shaped radiator, which can make the LED junction temperature more than 15℃ lower than that of the ordinary radiator. The waterproof performance is better than that of the ordinary aluminum radiator and also improved in weight and volume.

EXC-CR-Z01 led solar street light use integrated die-casting heat dissipation lamp body design to ensure excellent heat dissipation and long lifespan. The power of this high performance street light is optional from 10W to 150W. It uses high performance monocrystalline solar panels with high conversion rate.
