The current mainstream lighting sources are: incandescent lamps, fluorescent lamps, energy-saving lamps and LED lamps. The incandescent lamp was invented by Edison. It is a light source of thermal radiation. The filament needs to be heated to an incandescent state to emit visible light. The core temperature of the filament is as high as 2000℃~3000℃, and its luminous efficiency is very low. Later smart humans invented more energy-saving fluorescent lamps and energy-saving lamps. Fluorescent lamps and energy-saving lamps both need ultraviolet rays to excite phosphors to emit light. They do not generate a lot of heat like incandescent lamps, so they are more energy-efficient, but most of the energy is used to generate ultraviolet rays, so the luminous efficiency is relatively low. LED lamp is a kind of semiconductor device, which is currently recognized as the most energy-saving lighting source.
