Problems solved by technology

Although the luminous flux of a single LED can reach 5-20 lumens at present, the output light power is limited after all.
Using multiple LEDs arranged into a large-area light-emitting panel can increase the output light power to a certain extent, but because the area of ​​the light-emitting panel is too large, it is impossible to obtain high optical power density in a small illuminated area, which is easy in practical applications
