The ignition when the filament temperature is very high, so the selection of high melting point materials, tungsten filament, filament by evaporation in order to suppress the fine, the lamp filled with argon, nitrogen or argon and nitrogen mixed gas, inert gas, only a few small power bulbs is vacuum. Halogen tungsten halogen lamp is the incandescent light bulb filled with trace halide filament temperature than common incandescent lamp, tungsten halide bulb to evaporate and the formation of tungsten halogen tungsten filament, with the decomposition of tungsten to so recycling, which can improve the luminous efficiency and prolong the service life. The gas discharge light source can be divided into Fluorescent lamp hpmv Special light source Fluorescent lamp, also known as fluorescent lamp, is the most widely used gas discharge light source. It is ionized by mercury vapor to form a gas discharge, which results in the luminescence of the fluorescent material in the tube wall. Fluorescent tube wall coated with fluorescent powder, with both ends of the tungsten electrodes, vacuum tube was filled with a small amount of inert gas argon and mercury, mercury is a main material lamp, argon is to reduce the sputtering voltage and cathode material suppression lamp starting at startup, prolong lamp life. The principle of fluorescent high pressure
