A class iic explosion-proof led explosion-proof lamp

Abstract

The invention discloses an IIC-grade flame-proof type LED explosion-proof lamp. The lamp comprises a lamp shell, a power cavity, a wiring cavity, a plurality of IIC-grade flame-proof type LED explosion-proof units, wherein the power cavity is provided with a flame-proof structure, and the IIC-grade flame-proof type LED explosion-proof units are connected in parallel. Each IIC-grade flame-proof type LED explosion-proof unit is composed of a transparent cover, an LED light source module and a heat dissipation shell, wherein the transparent cover is a transparent plastic piece with an embedded metal piece, matched flame-proof threads are machined on the metal piece and the heat dissipation shell, and the heat dissipation shell is connected with the transparent cover through the flame-proof threads. The IIC-grade flame-proof type LED explosion-proof lamp can flexibly achieve various power requirements according to needs, can achieve partial maintenance and lowers the use cost; in addition, the wall thickness requirements of shells of high-power IIC-grade flame-proof type LED explosion-proof lamps can be reduced, the manufacturing cost can be saved, the stability of the explosion-proof performance can be guaranteed, and the applicability is high.

Description

technical field [0001] The invention relates to an explosion-proof lamp, in particular to an IIC-level explosion-proof LED explosion-proof lamp, which belongs to the technical field of explosion-proof lighting. Background technique [0002] Explosion-proof lamps are used in hazardous places where flammable gases and dust exist, and can prevent the possible arcs, sparks and high temperatures inside the lamp from igniting the flammable gases and dust in the surrounding environment, so as to meet the requirements of explosion-proof lamps. Explosive type, increased safety type, intrinsically safe type, positive pressure type, oil-filled type, sand-filled type, non-spark type, special type, etc., are mainly used in flammable and explosive places in petrochemical, mining, chemical and other industries. The explosion-proof area can be divided into Zone 0 formed by continuous release sources, Zone 1 formed by Class 1 release sources, and Zone 2 formed by Class 2 release sources. Th...
