The filament is mainly used as filament for tungsten halogen lamps, because the recrystallized structure of tungsten filament can form a good dovetail overlap structure. The aspect ratio is greater than 12. It has high high-temperature strength under high-temperature ignition point and good high-temperature anti-sag and deformation resistance. It also has high room-temperature strength and good ductility under non-ignition point, that is, normal temperature, which extends the service life of the tungsten halogen lamp; The high-temperature anti-sag performance of tungsten wire used in halogen lamps is improved and the winding performance in the lamp-making process is improved. A tungsten halogen lamp is a lamp in which an incandescent lamp is filled with some halogen elements or halide.
The power of tungsten halogen lamps is 5W, 10W, 15W, 20W, 25W, 30W, 35W, 40W, 45W, 50W, 60W, 70W, 100W, 150W, 200W and 250W. The working voltages include 6V, 12V, 24V, 28V, 110V and 220V. The lamp caps include screw-type (E10, E11, E14, etc.), plug-in type (GU5.3, GX5.3, GY6.35, GZ4, G8, etc.) and direct lead-out type. Among them, cup lights are also available with or without a front cover. Cup mouth diameters include 25mm (MR8), 35mm (MR11) and 50mm (MR16). Reflection angles include 8°, 10°, 12°, 20°, 24°, 30°, 36°, 40° and 60°.
Tungsten halogen lamp uses:
It is suitable to be used in places with high illumination requirements, good color rendering or dimming requirements, such as gymnasiums, conference halls, banquet halls, etc. Its color temperature is particularly suitable for studio lighting for color television. Due to its high working temperature, it is not suitable for places with dusty, flammable, explosive, corrosive environments, and places with vibration. Quartz condenser tungsten halogen lamps are used in spotlights or backlights for film, television and stage lighting.
