Abstract
The invention discloses an anti-explosion fire protection emergency sign lamp. A breathing limiting type anti-explosion mode is adopted to a lamp body inner cavity of a lamp body, and the lamp body comprises a pressing plate, a panel, an LED power driving device, a cable leading-in device, a main shell, a battery, a self-inspection PCB and a switch ejector rod. The pressing plate and the panel are in sealing fixation with the main shell through a sealing ring, the switch ejector rod is in sealing fixation with the main shell through an O-shaped ring, a spring and an elastic stopping ring, the cable leading-in device enables a cable to be fixed on the main shell through a gland nut, a gasket and a cable sealing ring, the LED power driving device is fixed on the main shell through a screw and a spring washer, and the self-inspection PCB is fixed on the main shell through a screw and a spring washer. According to the anti-explosion fire protection emergency sign lamp, the lamp body inner cavity in the breathing limiting type anti-explosion mode is formed in the lamp body, the anti-explosion fire protection emergency sign lamp is suitable for serving as road sign indicating and safe escape indicating for a second area with the potential explosion hazard gaseous environment, and the requirements of GB17945-2010 fire protection emergency lighting and escape indicating systems are met.
Description
technical field [0001] The invention relates to a lighting device, in particular to an explosion-proof fire emergency sign lamp. Background technique [0002] At present, the existing explosion-proof emergency sign lamps generally adopt flameproof shells, and the existing explosion-proof emergency sign lamps have the following defects: [0003] 1) Lamps with flameproof enclosures are too heavy; [0004] 2) It cannot meet the environmental requirements for the use of tobacco phosphine; [0005] 3) The installation method is single, and embedded installation cannot be performed; [0006] 4) It does not meet the requirements of the standard "GB 17945-2010 Fire Emergency Lighting and Evacuation Instruction System". [0007] Therefore, there are defects in the prior art and need to be improved. Contents of the invention [0008] The technical problem to be solved by the present invention is: to provide an explosion-proof form with restricted breathing in the inner cavity of...
