However, all modular light sources in the market are subject to technical factors, and they are not really light source components. They are just light source components that integrate LED light sources, light distribution lenses, sealing rings and radiators. The driving power can only The power connection line is put aside separately; the reliability of the integrated optical module solution that integrates the driver and LED light source into the light board using the IC solution is still technically unresolved, and cannot be used in practical applications on a large scale.
