Everyone knows that the area affected by smog in the country is so vast; it not only harms people’s health but also causes significant light decay for solar street lights, especially in northern regions where there is much dust and smog. After a short period of outdoor use, the surfaces of solar street lights become covered with dust, significantly reducing their heat dissipation effectiveness. This is one of the major reasons why solar street lights are not widely recognized.
Given this situation, the design of the fixtures is open on both ends to greatly increase the heat dissipation area, as no streetlight management department will clean the heat sinks on time. Over long-term use, reliance on rain for cleaning leads to a reduction in effective heat dissipation area due to pollution.
The light decay of solar street lights has a bucket effect, meaning that even one short board can cause issues. Light decay has troubled many for years, and the misunderstanding is that improving the heat sink alone can resolve light decay. It is not that simple; discussions have centered around using low-power chip bullet-type packaging, while high-power chips present difficulties. One may believe that high-power chips cannot dissipate heat effectively, but this is not true. COB packaging concentrates heat, and this can be satisfactorily resolved using aluminum or copper brackets.
However, controlling light decay is more challenging. The reason is that a well-designed heat sink does not necessarily resolve the light source’s decay issues. There is a significant misconception surrounding the light source packaging; the silicone used in COB light sources is often too thick. The silicone should be as thin as possible to aid heat dissipation from the chip’s light-emitting surface. This is where control over COB light source decay becomes problematic.
