LED car lights and HID car lights What is the difference
Xenon lamp light principle is UV-cut UV crystal quartz glass tube, with a variety of chemical gas filling, most of which is xenon (Xenon) and iodide, etc., and then through the supercharger (Ballast) will car 12 volts of DC voltage instantaneous boost to 23,000 volts of the voltage, through the high voltage amplitude excitation quartz tube xenon electrons free, between the two electrodes to produce light, which is the so-called gas discharge. And by the xenon produced by the white super arc light, can improve the color temperature of light, similar to the sun in the daylight, HID work required when the current is only 3.5A, the brightness is three times the traditional halogen bulb, the service life than the traditional Halogen bulb is 10 times longer.
LED (Light Emitting Diode), a light-emitting diode, is a power can be converted into visible light solid-state semiconductor devices, it can be directly into electricity into light. The heart of the LED is a semiconductor chip, one end of the chip attached to a bracket, one end is negative, the other end connected to the power of the positive, so that the entire chip is encapsulated by epoxy resin. Semiconductor chip consists of two parts, part of the P-type semiconductor, which in it dominate the hole, the other end is the N-type semiconductor, mainly electronic here. But when the two semiconductors are connected, they form a P-N junction. When the current through the wire acting on the chip, the electron will be pushed to the P area, in the P area with the hole in the electronic composite, and then will be issued in the form of photon energy, which is the principle of LED light. And the wavelength of light is the color of light, is formed by the formation of P-N knot material.
LED is the light-emitting diode directly into electrical energy, xenon lamp is high voltage through the bulb xenon discharge light
