Description

Technical Field

[0001] The utility model relates to the technical field of lighting, in particular to an explosion-proof ceiling lamp. Background Art

[0002] An explosion-proof lamp refers to a lamp used in dangerous places where combustible gases and dust exist. Explosion-proof lamps are widely used in industries such as petroleum, chemical industry, mining, and power plants. Due to considerations of use convenience and safety, there is a need for intelligent transformation of explosion-proof lamps.

[0003] In traditional explosion-proof ceiling lamps, the light source board and the power supply board are placed in the same chamber and directly covered by the lampshade. If an explosion occurs inside the lampshade by accident, the lampshade is easily blown open directly, thus affecting the external environment. Moreover, when installing traditional explosion-proof ceiling lamps, one needs to hold the bottom of the lamp with one hand and screw the lamp at the same time, making the installation extremely inconvenient. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an explosion-proof ceiling lamp, in which the power supply board is placed separately on the top of the explosion-proof shell, the light source board is placed at the bottom of the explosion-proof shell, and then the lampshade covers the bottom of the explosion-proof shell, avoiding safety accidents caused by the power supply board.
