Explosion-proof LED dust-free purified fixture lamp

Abstract

The invention relates to an explosion-proof LED dust-free purified fixture lamp which comprises an explosion-proof LED dust-free purified fixture lamp body. The explosion-proof LED dust-free purified fixture lamp body comprises an aluminum alloy sealed backing plate, a first aluminum alloy sealed side plate and a second aluminum alloy sealed side plate. A first positioning lug boss and a second positioning lug boss are respectively arranged on two sides of the aluminum alloy sealed backing plate. A plurality of grooves are formed in the top surface of the aluminum alloy sealed backing plate. A parting strip is arranged between any two adjacent grooves. A transparent high temperature resistant explosion-proof layer, a color rendering property enhancing and brightness enhancing plate, a light guide plate and a shaping backing plate are sequentially arranged on the top surface of each parting strip from top to bottom. The transparent high temperature resistant explosion-proof layer is pressed by a first extension wing and a second extension wing. First sealed washers are fixedly arranged at two ends of the explosion-proof LED dust-free purified fixture lamp body. A plastic plug suite or an aluminum alloy die-cast plug suite is arranged outside each sealed washer. The two ends, the upper part and the lower part of the explosion-proof LED dust-free purified fixture lamp body are in the completely sealed state, the explosion-proof level reaches the requirement of the national standard 3836.1-2010, and the requirements on the explosion-proof levels in an industrial plant, a mine shaft, a medicine plant and a chemical medicine plant are met.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to an explosion-proof LED dust-free purification lamp. Background technique [0002] A light-emitting diode (LED for short) is a solid-state semiconductor device that can convert electrical energy into visible light. It uses a semiconductor wafer as a light-emitting material. When a forward voltage is applied to both ends, the carriers in the semiconductor recombine to cause photon emission. The generation of light is currently the most popular researched light source technology. It has the characteristics of high quality, durability, energy saving, and short response time. At the same time, it has good applicability. Because of the small size of a single LED lamp bead, it can be made into any shape. These characteristics of the lamp set off the reform of LED lamps instead of fluorescent lamps. [0003] Because of the advantages of energy saving and high brightness of LED lamps, ...

Problems solved by technology

[0005] However, there are defects in the above-mentioned structure, the explosion-proof level is low, the sealed internal space is large, the larger the internal space, the larger the stored air, the greater the impact force when an explosion occurs, the higher the protection level required for the lamps, and only Using elastic sealing gaskets to achieve sealing, the effect is not obvious enough, and further improvement is needed to truly achieve real explosion-proof
