Problems solved by technology

[0004] However, under some specific working conditions, high-power lighting needs to be provided continuously for 24 hours. Long-term high-power lighting will cause LED lights to generate a lot of heat. When the heat exceeds a certain value, it will affect the service life of internal devices, and even explosion hazard

Abstract

The invention provides a self-power-off explosion-proof lamp with a high-temperature protection function, which comprises a lamp body, wherein the lamp body comprises a shell, an LED lamp panel arranged in the shell and a light-transmitting cover positioned at the light-emitting end of the LED lamp panel, and a power line is arranged at the top of the lamp body; a first radiator mounted on the rear surface of the LED lamp panel in an attached manner and used for absorbing heat on the LED lamp panel and radiating the heat; and an electric connector assembly used for connecting the power line and the LED lamp panel, wherein the electric connector assembly internally comprises a connecting mechanism with a heat collecting function, and when heat absorbed by the connecting mechanism exceeds a threshold value, expansion is generated, and connection between the power line and the LED lamp panel is cut off. The self-power-off explosion-proof lamp with the high-temperature protection function is compact in structure and good in heat dissipation effect, mechanical power off can be achieved when the temperature is too high, safety and reliability are achieved, the service life of the lamp body is prolonged, reconnection can be achieved manually after high-temperature power off, and operation is convenient and fast.

Description

technical field [0001] The invention relates to an explosion-proof lamp, in particular to a self-cutting explosion-proof lamp with high temperature protection. Background technique [0002] With the rapid development of science and technology, lighting fixtures are used more and more widely in production, storage and rescue, and there are more and more varieties. Since lighting fixtures usually use metal halide lamps or fluorescent lamps as light sources, electric sparks or hot surfaces will inevitably be generated during work. Once they meet explosive gas, dust or their mixture at the production or rescue site, they will be lead to explosion accidents. Therefore, how to prevent the occurrence of explosion accidents of lighting fixtures has become a very important issue in dangerous places where explosive gas, dust or their mixtures exist. Existing explosion-proof lamps achieve the purpose of explosion protection by limiting the temperature of the surface of the shell wher...
