Incandescent lamp, tungsten lamp, fluorescent lamp, fluorescent lamp, what's the difference?
Incandescent: Tungsten wire due to the thermal effect of heat and light, so it is a hot light source, features: low luminous efficiency, continuous spectrum, low color temperature.
Energy-saving lamps: improved version of the fluorescent: fluorescent lamp in the ball, and large, and easy to produce noise, low efficiency, energy-saving lamps is the coil to do the ballast to use electronic circuits to do, the efficiency improved, no sound The other the same. But the life of energy-saving lamps is too short.
Fluorescent luminous efficiency is much higher than incandescent, but the color is not true, not continuous spectrum, color is not good.
Fluorescent lamp: the use of mercury in the lamp vapor in the electric field issued by the principle of ultraviolet light, direct ultraviolet light, is used for disinfection of the UV lamp, home fluorescent lamp is added to a coating on the tube, the coating on the UV Into visible light
Iodine tungsten lamp: is the improvement of incandescent, vacuum added iodine, heat after the transport effect, to tungsten atoms "transport" back to the filament, the light source temperature, power, long life
