Solar street lights can be heat dissipation by heat-conducting plate, which distributes the heat generated by solar led street lights to a conductor, and the heat is exported outside the lamp head through a meson, so that the heat is dissipated. Heat sink heat dissipation: Some street light heads are retrofitted with heat sinks to dissipate heat, but the weight is too large.
The heat dissipation efficiency of the needle radiator than the traditional sheet radiator has been greatly improved, can make the LED junction temperature than ordinary radiator more than 15 ℃ lower, and waterproof performance than ordinary aluminum radiator is better, while the weight and volume has also been improved.
Solar street lights are largely used LED as a light source, can LED lights in the electricity flow through, will glow and fever, in general the main source of fever is the current reverse through the LED when a lot of occur.
If the solar road lamp heat dissipation is poor, one will accelerate the LED lamp life depreciation, the second is to affect the lighting effect, persistent poor heat dissipation will lead to LED light decay increased, the third is the fever accumulation will lead to lamp head and other related understanding of equipment aging, affecting the use. Larger power solar street lights will also use aluminum lamp base, and carved out the shape of faster heat dissipation effect, increasing the heat dissipation area. Solar street lights to dissipate heat can also be adjusted through the controller to reduce LED fever, this move can save energy, but also to reduce heat.
