Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0027] In order to meet the requirements of hazardous places such as explosive gas and dust, LEDs need to be explosion-proof in structure. First of all, the LED explosion-proof lamp is designed as two modules of light source and power supply, and the power supply part with the greatest risk of electric sparks is packaged in a separate explosion-proof cavity. Secondly, in order to reduce the surface temperature of the LED explosion-proof lamp so that it will not rise to a dangerously high temperature, the heat dissipation problem of the lamp must be handled well, and a good heat dissipation channel should be designed for the heat emitted by the LED. The metal used as the substrate of the lamp.

[0028]As shown in the figure, the LED explosion-proof lamp includes a main light source bracket 4. The bottom of the main light source bracket 4 is a disc st...

Abstract

The utility model relates to an explosion-proof LED lamp driven by a switching power supply, belonging to explosion-proof lighting fixtures. It is characterized in that it includes a main light source bracket, the bottom of the main light source bracket is a disc structure, and the upper part is a cylindrical ring structure, a cylindrical auxiliary light source bracket is arranged in the through hole of the cylindrical ring of the main light source bracket, and a main light source bracket is arranged on the surface of the cylindrical ring of the main light source bracket. The light source aluminum substrate light bar, the main light source LED string is packaged in lens A and installed on the main light source aluminum substrate light bar; the auxiliary light source aluminum substrate light bar is set on the cylindrical surface of the auxiliary light source bracket, and the auxiliary light source LED string is packaged in lens B and installed on the auxiliary light source aluminum substrate light bar; the disc at the bottom of the main light source bracket is connected with the explosion-proof cavity, and the circuit board is installed in the explosion-proof cavity. The above-mentioned LED explosion-proof lamp driven by a switching power supply improves the reliability of the LED explosion-proof lamp, reduces the production cost, reduces the mean time between failures, and is easy to maintain.

Description

technical field [0001] The invention belongs to an explosion-proof lighting fixture, in particular to an explosion-proof LED lamp driven by a switching power supply. Background technique [0002] Explosion-proof electrical products are mainly used in many places such as underground coal mines and petrochemical production workshops. There are a large number of flammable media such as methane, coal dust, dust, etc. in the working environment. There are many factors that cause explosions, but mainly the sparks generated during the operation of electrical equipment and temperature. In order to prevent these sparks and temperature from causing the explosion of the surrounding flammable medium, explosion-proof products must ensure that the sparks and high temperatures generated on the internal electrical circuit do not spread to the surrounding medium, that is, the shell must be able to withstand the internal explosion pressure, or extinguish the spark, Even if the temperature dr...
