Description

Technical Field

[0001] The utility model relates to the technical field of tungsten halogen lamps, in particular to an explosion-proof tungsten halogen bulb. Background Art

[0002] Halogen tungsten lamps are gas-filled incandescent lamps that contain some halogen elements or halides in the filling gas. In ordinary incandescent lamps, the high temperature of the filament causes the tungsten to evaporate, and the evaporated tungsten is deposited on the glass shell, causing the glass shell of the bulb to turn black. Halogen tungsten lamps are divided into two types: high-voltage halogen tungsten lamps (can be directly connected to a 220V-240V power supply) and low-voltage halogen tungsten lamps (need to be equipped with a corresponding transformer). Low-voltage halogen tungsten lamps have relatively longer life and safety performance.

[0003] The infrared explosion-proof bulb with application number 202022481046.3 in the prior art includes a bottom shell and an electric telescopic rod. A reserved wire box is fixedly installed at the bottom of the inner cavity of the bottom shell. A protective tube is fixedly installed at the bottom of the bottom shell. The bulb can be hidden in the protective tube when not in use by providing a protective tube, a micro-blower and an electric push rod to prevent the bulb from being exposed to the outside for a long time and being corroded and damaged by dust and other substances in the air. The micro-blower can effectively help the bulb to dissipate heat, and can also clean the dust on the bulb by blowing. The hollow layer and the quartz glass layer can prevent the bulb from bursting due to excessive temperature and contact with dust in the air. The quartz glass layer has good wear resistance, which reduces the chance of the bulb bursting. However, the protection area of ​​the explosion-proof mesh cover is narrow, which makes it difficult to meet the explosion-proof requirements of explosion-proof ribs at different horizontal positions, thereby affecting the service life of the halogen tungsten bulb.
