The invention relates to an LED explosion-proof lamp. The LED explosion-proof lamp comprises a sectional material lamp housing, four or six cooling fins attached to the sectional material lamp housing, two small cover plates installed on the sectional material lamp housing, a light distribution assembly (two LED modules, two reflection cups and a reflection cup pressing plate) installed on the sectional material lamp housing, an LED driving power source installed in an electric appliance cavity of the sectional material lamp housing, a lower cover installed on the sectional material lamp housing, a transparent piece and a protecting cover, wherein the transparent piece and the protecting cover are installed on the lower cover. The sectional material lamp housing is provided with a round through hole with the diameter of 70 mm, the wall thickness of the through hole is 3 mm or larger, and the sectional material lamp housing is formed in an extruding mode. The four or six cooling fins attached to the sectional material lamp housing are hollow, the two sides of each fooling fin are hollow through extrusion forming, the other two sides of each cooling fin are provided with through holes, it is guaranteed that ventilation can be performed on the four sides of each cooling fin, and heat of the LED explosion-proof lamp can be taken away through flow of air; heat generated by the LED explosion-proof lamp can also make air flow so that heat of the lamp can be taken away.
Description
technical field [0001] The present invention relates to a lighting fixture, more specifically to a LED explosion-proof lamp especially suitable for explosive environments Background technique [0002] At present, the LED explosion-proof lamps used in explosive environments adopt upper, middle and lower structures. Due to structural defects, the lamps are too long or too high, which affects installation and use; the cooling system (heat sink) has poor air convection or cannot convect. The overall temperature of explosion-proof lamps is high; the electrical cavity is located between the light source cavity and the wiring cavity, and the working environment temperature of the LED driver board is high, which shortens the service life. Affect the lighting needs of explosion-proof areas, bring a lot of inconvenience to production activities, and affect production efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to pro...
