One is that the price is higher than other light sources; As we all know, due to the single light source form of traditional lamps, lamps have already matured and standardized forms, while LED light sources have not yet standardized light modules, which is a great bottleneck for the promotion of LED lights. Due to its small light-emitting angle, the LED light source requires the cooperation of optical lenses to achieve a traditional light-emitting angle. The high cost means that the LED will not scrap the entire optical module when it fails, but only needs to replace the LED light source. In the existing technology, when repairing or updating LED lamps, it is often seen that the staff disassemble the lamp panel of an entire LED street lamp, and then replace the damaged light source. The maintenance time is long and the process is cumbersome, so the LED lamp industry There is an urgent need for a standardized component module like traditional incandescent light bulbs, which not only has excellent energy-saving effects, but also can be sold as a single product in a simple form, and is easy to install and maintain, so it can be better introduced to the market.

In the LED lighting industry, high-power integrated light source lamps generally adopt passive heat dissipation, using aluminum alloy as the main heat dissipation material, which is not only large in size but also heavy in weight, and its heat conduction effect is average, which cannot effectively solve the heat dissipation problem of high-power integrated light source. The problem of heat dissipation efficiency has become the main bottleneck restricting the further application and development of integrated light sources.
