1. halogen headlamps
is filled with a halogen element such as iodine, bromine or a tungsten halide or tungsten halogen lamp referred halogen. It is a new generation of incandescent. In order to improve the luminous efficiency of the incandescent lamp, the tungsten wire temperature must be increased, but the corresponding evaporation of tungsten will cause the bulb black. Was filled incandescent halogen element or a halide, using the principle of the tungsten halogen cycle can be eliminated incandescent bulb blackening. This is the reason halogen lamps. However, to ensure the normal tungsten halogen cycle, must be significantly reduced envelope size, to increase the temperature of the bulb (halogen lamp bulb generally require a temperature of 250-600 deg.] C, bromine tungsten lamp bulb temperature of 200-1100 ℃ ), the tungsten halide lamps in a gaseous state. Thus, the halogen lamp bulb must be used in high-temperature and high mechanical strength of the quartz glass. The structure has a double-ended straight tubular, single-ended cylindrical shape, and reflection. Since the quartz glass bulb as, and often called halogen quartz lamp. Wherein reflected by a halogen lamp with a reflector cup-shaped, and often called cup lamp. There 5W, 10W, 15W, 20W, 25W, 30W, 35W, 40W, 45W, 50W, 60W, 70W, 100W, 150W, 200W and 250W tungsten halogen variety of power. There 6V, 12V, 24V, 28V, 110V and 220V, and other operating voltage. Have screw-on cap (E10, E11, E14, etc.), insert (GU5.3, GX5.3, GY6.35, GZ4 G8, and the like), and leads directly to the formula. Wherein the front lights and the cup with a cover and the front cover without division. Cup diameter 25mm (MR8), 35mm (MR11) and 50 mm (MR16) and other types. There reflection 8deg;, 10deg;, 12deg;, 20deg;, 24deg;, 30deg;, 36deg;, 40deg; and 60deg; other.
