The principle is pours into halogen gas and so on iodine or bromine in the light bulb. Under the high temperature, the evaporation tungsten wire and the halogen will carry on the chemical action, the evaporation tungsten will coagulate in the tungsten wire, will form the balanced circulation, will avoid the tungsten wire premature break. Therefore the halogen bulb compares the incandescent lamp longevity. In addition, the halogen bulb can also by compared to the common incandescent lamp higher temperature operation, their brightness and the efficiency is also higher. However under this temperature, the simple glass will possibly soften. Therefore the halogen bulb needs to use the melting point higher quartz glass. But because halogen bulb the quartz glass cannot be cut off the ultraviolet ray, therefore halogen bulb usually but needs other use ultraviolet ray to filter the mirror
