The structure and function of the lamp

Gas discharge lamp is composed of small-scale quartz light bulbs, transformers and electronic controller, through the transformer boost to 0.5 to 12,000 volts of high-voltage power to stimulate small-scale quartz light bulbs, the brightness than the moment with the halogen light 2.5 times the bright color of the shot is very similar to the sun light, and the power light is shiny and reaches the temperature of the designated things, the power consumption of only 35 watts, one-third lower than the halogen lamp, it is economical, very affordable Used as a car headlamp
Headlamp assembly is to protect the safe operation of the car one of the important components, headlamps according to the interval between the light, the better light distribution characteristics, the higher the safety of motor vehicles with the development of car skills, the car headlamps There are also great changes in the car, the past that the self-incandescent lamps and incandescent vacuum headlamps have been cut, and replaced the halogen headlamps, a few years to cover the world Kung Fu, to become the front of the sedan The main light of the car The general car electric lamp is composed of a tightly wound thin tungsten wire installed in a lamp filled with inert gas. When it passes through the tungsten wire, it burns and emits white light Light, at very high temperature utility, the tungsten atoms in the tungsten living evaporation state, over time, the evaporation of tungsten atoms will be more and more, the more the more narrow the tungsten filament, the final was blown, the Tungsten Atomic Society Stained in colder relative to the gallbladder glass, over the years there will be a layer of shadow, covering the light of the irradiation.
The brightness of the lamp will be weakened. Electro-optical engineers developed the halogen lamp for the above-mentioned problems that need others to answer. Such lamps are the infiltration of a small amount of iodine (iodine is a halogen element in chemical elements) Tungsten atoms emitted from the filament evaporate and react with iodine atoms to produce a natural tungsten iodide compound. When a tungsten iodide compound is touched and triggered, a whitened filament (temperature over 1450 ° C) will be induced and differentiated to tungsten and Iodine, tungsten and rejoin the filament back from scratch, iodine is endlessly into the gas cloud endless loop, almost no blown filament, the lamp will not be black So halogen headlamps than the traditional incandescent front Lamp life longer, more brightness At the moment halogen glass is made of quartz, also known as quartz halogen lamps, can withstand high temperatures Halogen lamps are mainly used as a car headlamps, has its peculiar distribution Light structure Each lamp has two groups of filaments, a group of the main beam filament, shot for the light reflected by the lamp reflector after the diameter of the straight into the shooting, such light source commonly known as "high beam"; the other group is the polarizing column filament, The light sent to the shading block shade mirror the upper half of the door, which reflects the light out of the petals are diffuse downward to the ground, will not cause dazzling drivers across the car, commonly known as "light near Light".
