Abstract

The invention relates to an LED anti-explosion lamp which comprises a shell, wherein the LED anti-explosion lamp consists of a front light source cavity, a rear electric appliance cavity and a heat radiating cavity positioned between the front light source cavity and the rear electric appliance cavity, the light source cavity and the electric appliance cavity are closed cavities and are capable of preventing electric sparks from leaking, heat radiating through holes are arranged on the circumferential wall of the heat radiating cavity, the light source cavity is internally provided with an LED module, the electric appliance cavity is internally provided with a power supply driver adapted with the LED module, an electric wire connected with the power supply driver and the LED module is led to the light source cavity from the electric appliance cavity after passing through a sealing sleeve membrane; and a heat radiating sheet is connected to the LED module in the light source cavity, and the rear end of the heat radiating sheet is communicated with the heat radiating cavity. The invention has the advantages of good heat radiation effect, dust explosion prevention, high safety and long service life of the LED lamp.

Description

technical field [0001] The invention relates to an LED explosion-proof lamp. Background technique [0002] In industrial mines and workshops with flammable gas and flammable dust environments, incandescent lamps powered by 220V AC are mostly used as lighting fixtures. Since the voltage exceeds the safe voltage of the human body, it is not safe to use; and flammable gas and flammable dust and high voltage electricity Spark contact is prone to explosion, and the explosion-proof performance is poor; while LED lamps are powered by low-voltage DC, which has low voltage and low heat generation, and has the advantages of explosion-proof itself, so LEDs are more preferred explosion-proof lamps, but from the perspective of explosion-proof, It is also necessary to solve the heat dissipation problem of the LED lamp. ZL200820037404.8 "High-power cold light source explosion-proof lighting" discloses an LED explosion-proof lamp, the LED illuminant and the driving circuit are separated by...
