Description

Technical Field

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

[0002] Explosion-proof lamps are used in dangerous places where flammable gases and dust exist. They can prevent the arc, sparks and high temperature generated inside the lamp from igniting the flammable gases and dust in the surrounding environment, thus meeting the explosion-proof requirements. They are also called explosion-proof lamps and explosion-proof lighting lamps. Explosion-proof lamps generate a lot of heat during use, especially when used for a long time. The heat generated by explosion-proof lamps will affect the service life of explosion-proof lamps.

[0003] The utility model patent with the publication number CN219867792U discloses an explosion-proof lamp, including a lamp housing, a power box for power control installation is provided at the center of the end face of the lamp housing, and circular lamp board slots for lamp board installation are provided on both sides of the power box. The flowing cold air passes through the convection holes formed between the lamellar heat dissipation ribs and the convection flow slots provided on the side of the heat dissipation area, so that the cold air can flow through the lamellar heat dissipation ribs to the two sides of the lamp housing and pass through the convection holes to the surface of the lamp housing to achieve the heat dissipation effect on the surface of the explosion-proof lamp, and the convection holes are provided on both sides of the lamp housing. No matter which side the cold air blows in, it can flow to the entire explosion-proof lamp through the cooperation of the lamellar heat dissipation ribs and the convection holes to take away the heat and dissipate the heat, and the heat emitted around the surface of the explosion-proof lamp can be quickly taken away to accelerate the heat dissipation effect, thereby making the heat dissipation effect of the explosion-proof lamp better. Although this technology can dissipate heat for the explosion-proof lamp and increase the service life of the explosion-proof lamp, this technology cannot adjust the angle of the explosion-proof lamp as required, and its applicability is poor.

In this way, the lighting direction of the explosion-proof lamp body can be adjusted as needed to meet different lighting needs;

[0045] 2. By inserting the bolts through the positioning holes, the mounting plate is fixed at the required lighting position, which is easy to install and disassemble;

[0046] 3. The power source provides the required energy to drive the fan to rotate.
