Halogen Lamps

Halogen Lamps

Halogen Lamps also higher than the average incandescent temperature operation, higher brightness and efficiency. However, in this temperature, the ordinary glass may be softened. Halogen bulb using a melting point higher quartz glass. Quartz glass does not block UV light, therefore halogen bulbs usually need another UV filter.

Halogen taking a dip in the crystal glass oil will result in different temperature on the glass to reduce the life of the bulb. Therefore, to change the halogen bulbs to avoid a staff to touch the bulb glass. If your fingers touch the clean alcohol.

alogen bulbs is the biggest difference with other incandescent and halogen glass enclosure filled with a halogen element, gas (usually iodine or bromine), and its working principle is: When the filament heating tungsten atoms evaporatedmove in the direction of the glass wall when close to the glass wall, tungsten vapor is cooled to approximately 800 ° C and halogen atoms combine to form a tungsten halogen (iodide, tungsten or tungsten) bromide. Tungsten halogen continue to move to the glass tube central, back on the oxidation of the filament, the tungsten halogen is a very unstable compound, when heated, and then re-decomposed into a halogen vapor and tungsten, so tungsten filament deposited on down, to compensate for the evaporated part. Through this recycling process, the life of the filament has not only been greatly extended (almost four times that of incandescent), filament can operate at a higher temperature, resulting in a higher brightness, higher color temperature and higher luminous efficiency.
