Embodiment Construction

[0028] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered by the claims.

[0029] see figure 1 The explosion-proof lamp of this application includes a power supply chamber and a light source chamber located on both sides of the radiator 17. In the light source chamber, an LED light source installation expansion disk 21 is installed between the surface of the radiator 17 and the light source. The LED light source installation expansion disk The diameter is 135mm, the thickness is 9mm, the material is 6063 aluminum alloy, and it is welded on the radiator. The functions of the expansion disk are: 1. to ensure the explosion-proof structure of the light source chamber; 2. to ensure the explosion-proof structure of the introduction device explosion-proof joint 4;

Abstract

The invention provides an LED explosion-proof lamp. The LED explosion-proof lamp comprises a power source cavity and a light source cavity located on two sides of a micro capillary groove composite phase change cooling heat radiator. In the light source cavity, an LED light source installation extension plate is installed between the surface of the micro capillary groove composite phase change cooling heat radiator and a light source. The lateral surface of the heat radiator is formed by a plurality of vertically arranged heat radiation fins in a surrounding mode, and gaps exist between the heat radiation fins. On the premise of not affecting explosion-proof safety, an explosion-proof structure and the micro capillary groove composite phase change technology heat radiator are combined, the low-efficiency heat radiation method that a traditional explosion-proof lamp only depends on an explosion-proof outer shell for heat radiation is changed, the LED lamp is more widely used in the explosion-proof field, and the lighting effect of the lamp and the reliability of the light source are higher. A power source and the light source are separated by the heat radiator, the heat radiation effect is reinforced, the temperature of the application environment of the power source is lowered, and the reliability and the service life of the power source are better guaranteed.

Description

technical field [0001] The present invention relates to the technical field of explosion-proof lamps, in particular, to an LED explosion-proof lamp. Background technique [0002] Explosion-proof lamps refer to lamps that are used in dangerous places where flammable gases and dust exist, and can prevent possible arcs, sparks and high temperatures inside the lamp from igniting flammable gases and dust in the surrounding environment, thereby meeting explosion-proof requirements; widely used in Petroleum, chemical industry, aerospace, coal, electric power, railway, metallurgy and other industries. Explosion-proof lamps with LED light sources as the light source are called LED explosion-proof lamps. The focus of explosion-proof lamps is to prevent explosive gases or dust from igniting the environment such as electric sparks generated under abnormal conditions. Therefore, it is necessary to separate the isolation cavity for the light source and the power supply to isolate the ext...
