What are the factors that affect the decline of solar street lights?

In fact, temperature is the key problem of solar street lights decay, but solar street lights are stuck in this link. Since the luminous power of solar street lamps is greater than that of household lamps, manufacturers have made great efforts in the design of heat dissipation substrate fins and heat dissipation modules. After assembly, they need to add baking paint to the outside of the lamp heat dissipation module to prevent weather erosion. Unexpectedly, the spray paint for external protection seals the heat of the heat dissipation module back, resulting in poor heat dissipation and light failure of the solar lamp epitaxy. The luminous heat energy of the lamp epitaxy belongs to a small range of concentrated heat energy. In the application of high-power street lamps, the power input power is also large, and the interface temperature of the solar lamp is quite high. When the street lamp continues to work for a long time, if the heat dissipation module cannot effectively dissipate heat, It will affect the service life and luminous performance of the solar lamp. For example, the serious light failure of the current solar street lamp is caused by these factors. Solar street lights are used outdoors, and there are environmental and climate interference factors, so most manufacturers protect the solar street light radiator shell with anodized treatment, or spray paint to avoid acid and alkali corrosion.
