Optical Tungsten Filament For Halogen Lamp LED Bulb Fluorescent Tube
1. Definition Of Optical Tungsten Filament For Halogen Lamp LED Bulb Fluorescent Tube:
Optical tungsten wire is the tungsten wire used in optical bulbs. The main optical bulbs can be divided into tungsten filament bulbs, tungsten halogen bulbs, fluorescent tubes, metal halide bulbs, and LED bulbs. The earliest optical tungsten filaments were used in tungsten filament bulbs. Then it is used in tungsten-filament halogen bulbs, which are more energy-efficient and brighter than tungsten-filament bulbs. Later optical tungsten filaments were also used to make fluorescent tubes. Its fibers are warmer, making it the best choice for kitchens and studios. Optical tungsten filaments that are widely used at present are mainly in LED bulbs. This type of bulb has the advantages of energy saving, longevity, and environmental protection.
