Description
Technical Field
[0001] The utility model relates to the technical field of lamps, in particular to an explosion-proof lamp. Background Art
[0002] Explosion-proof lamps are lighting fixtures with explosion-proof functions. They are mainly used in dangerous environments such as those with flammable and explosive gases and dust. They usually have explosion-proof properties and can prevent the arcs, sparks and high temperatures generated inside the lamps from igniting the surrounding explosive environment. They are usually used in the petrochemical industry, underground coal mines, ships and pharmaceutical industries.
[0003] Existing explosion-proof lamps also have the following problems when in use: the outer lamp housing is usually an explosion-proof lamp housing, and an explosion-proof power supply is provided in conjunction with the lamp structure. The outer side of the explosion-proof power supply is also an explosion-proof shell. Since the explosion-proof shell is made of a relatively thick metal material, its actual thermal conductivity is limited. After the overall explosion-proof lamp is used for a long time, the heat accumulated in the lighting module in the lamp housing and the heat accumulated in the power supply module in the explosion-proof power supply are difficult to dissipate quickly through the shell, which can easily lead to overheating and damage to the lamp and the power supply.
