Abstract

The invention discloses an energy-saving and safe halogen lamp. The energy-saving and safe halogen lamp comprises a glass shell, a tungsten filament, two tungsten filament support rods and a screw holder, wherein the tail portion of the glass shell is sealed on the screw holder, the tungsten filament is connected with the screw holder through the two tungsten filament support rods, the glass shell comprises an outer glass shell and an inner glass shell, a vacuum is formed between the outer glass shell and the inner glass shell through pumping, a transparent conducting thin film is respectively applied to the inner surface of the outer glass shell and the outer surface of the inner glass shell, and the inner glass shell is quartz glass. By means of the energy-saving and safe halogen lamp, thermal loss can be substantially reduced, electro-optical conversion efficiency can be improved, the surface temperature of the glass shell of the halogen lamp can be substantially reduced, and fire accidents caused by high temperatures can be avoided.

Description

technical field [0001] The invention relates to the fields of energy saving and lighting, in particular to an energy-saving and safe halogen tungsten bulb. Background technique [0002] The tungsten halogen lamp is an electric light source that emits visible light by heating the filament to an incandescent state through thermal radiation. Due to the advantages of simple manufacturing process, low cost, good color rendering, no special control circuit, and high power, tungsten-halogen lamps have always been one of the main lighting sources, especially in high-power lighting occasions. Although LED lighting has achieved great success in low-power lighting (one to ten watts), LEDs still cannot replace halogen tungsten lamps in terms of hundreds of watts or even kilowatts of lighting. [0003] The working principle of a tungsten-halogen lamp is similar to that of an ordinary incandescent lamp, but its glass shell is filled with halogen vapor. Halogen vapor can combine with tun...
