LED lamp principle: there are many people will have a certain interest in the principle of LED lamp. In fact, the biggest difference between LED lights and traditional incandescent lamps lies in the filament. Incandescent lamp because its lamp body is transparent, so can directly observe the state of the filament. But LED lamp is different, it takes the diode as the light source of the whole lamp tube, the lamp tube is coated with phosphor powder, when the diode emits light, phosphor powder helps to diffuse the light so as to achieve the lighting effect, this is the luminous principle of LED lamp, but the lamp tube hides a layer of connected to the left and right ends of the filament.
