What is the difference between Halogen and LED, Xenon
Halogen: halogen lamps with halogen incandescent filament inside, improve the luminous efficiency of an incandescent lamp, a tungsten filament temperature must be increased, but it will cause the evaporation of the corresponding tungsten bulb become black. In filling incandescent halogen element or a halide, using the principle of the loop can be eliminated halogen incandescent bulb blackening. The reason behind this is halogen. However, to ensure the normal halogen cycle bulb size must be significantly reduced in order to improve bulb temperature (generally require tungsten bulb temperature of 250-600 ℃, bromine tungsten lamp bulb temperature of 200-1100 ℃ ), so that the lamp is a tungsten halide gas. Thus, the halogen bulb must use high-temperature mechanical strength of quartz glass.
LED light: light-emitting diode is one of the characteristics is powered by electronic transitions phenomenon after light, high light efficiency, low power consumption. And LED lighting chips use a long time, so the theoretical life is up to 10W hours.
Xenon: HID is the abbreviation, can be called heavy metal lamps or Xenon lamps. Its principle is anti-ultraviolet radiation in the UV-cut crystal quartz glass tube, filled with a variety of chemical gases, a majority of whom, such as Xenon (Xenon) with iodide and an inert gas, and then through the supercharger (Ballast) the car 12 volt DC voltage instantaneously pressurized to 23,000 volts of electricity through high voltage amplitude excitation of xenon gas inside the quartz tube electronics free, light between two electrodes, which is called the gas discharge. The super-white light from the xenon arc generated, can improve the light color temperature value, similar to the daytime sun light, HID work required amount of current is only 3.5A, the brightness is three times than the traditional halogen bulbs, service life is 10 times longer than conventional halogen bulb. Characterized by high voltage needed before they can start.
