Why should solar street lights dissipate heat? Solar street lights can dissipate heat from thermal panels, distribute the heat generated by solar led street lights to a conductor, and export the heat outside the lamp head through mesons, thereby dissipating the heat. Heat sink heat dissipation: some street lamps are equipped with heat sinks to dissipate heat, but the weight is too large.

The heat dissipation efficiency of the needle radiator is greatly improved than that of the traditional sheet radiator, which can make the LED junction temperature more than 15 ° C lower than that of the ordinary radiator, and the waterproof performance is better than that of the ordinary aluminum radiator, and the weight and volume are also improved.

Solar street lights are mostly the use of LED as a light source, but LED lights in the electricity unblocked obsolete, will emit light and fever, in general, the main fever source is the current reverse through the LED occurs in large numbers.

If the solar street lamp heat dissipation is poor, it will speed up the LED lamp life loss, the second is to affect the lighting effect, the persistent poor heat dissipation will lead to the increase of LED light decay, the third is the accumulation of fever will lead to the lamp head and other related equipment aging, affecting the use. The solar street lamp with large power will also use aluminum lamp holder, and characterize the shape of faster heat dissipation effect, and increase the heat dissipation area.

Why should solar street lights dissipate heat? Solar street lights to heat can also be adjusted by the controller to reduce the LED fever, which can save energy, but also reduce the fever, kill two birds with one stone!

1. The luminous mechanism is different. Since led solar street lights are semiconductor devices, their effective life can reach 50,000 hours (that is, light attenuation is less than 30% after 50,000 hours), much higher than sodium lamps and metal halide lamps (their life is about 12,000-15,000 hours).

2. Because the led solar street light is a semiconductor material, there is no filament or other additional materials, so it has good impact resistance.

3. The color rendering index of led solar street lighting can reach more than 80, which is closer to natural light. In this case, the human eye can distinguish things more easily, which is conducive to driving safety. The color rendering index of high-pressure sodium lamps is only 20-30.
