Explosion-proof LED (light emitting diode) lighting module and combination thereof

Abstract

The invention provides an explosion-proof LED (light emitting diode) lighting module and combination thereof. The explosion-proof LED lighting module combination comprises at least two explosion-proof LED lighting modules which are mutually connected; each explosion-proof LED lighting module comprises a casing, a cover and an LED metal substrate, wherein the casing and the cover are mutually matched with each other, and the LED metal substrate is arranged in a sealing hollow cavity enclosed by the casing and the cover; an LED light source array formed by a plurality of LED lamps is arranged on each LED metal substrate; wire penetrating holes for cables to pass through are formed in two opposite end surfaces of each casing; butted components are formed on each casing; and the butted components comprise a pair of butted guide rails which penetrate through the casings in parallel, the butted guide rails are hollow pipelines, female threads are arranged on the inner wall of one end, and male threads screwed with the female threads are arranged on the external wall of the other end. The two butted guide rails are used for connecting each lighting module, and the module has the advantages of being simple in structure, convenient to assemble, simple and easy to use and firm to connect.

Description

technical field [0001] The invention relates to a lighting device suitable for explosion-proof workplaces, in particular to the connection structure between explosion-proof LED lighting modules. Background technique [0002] Explosion-proof lighting fixtures gradually adopt LEDs as light sources, which have inherent advantages. First of all, the light source adopts LED chip, which has a long working life (50,000 to 100,000 hours), high luminous efficiency, and natural and pure light color. Military-grade constant-current drive power supply with constant output current (current stability accuracy ±2.5%) ensures a long life of the LED light source; secondly, the power supply adopts a potting type constant-current power supply, and the input and output of the power supply adopt an isolated design, so it does not run Arcs, sparks and dangerous high temperatures will be generated; wide voltage input or DC input, the output is equipped with short circuit, overvoltage and overheat...

AI Technical Summary

Problems solved by technology

However, the classification of power levels is quite confusing. The power levels of various manufacturers range from 15W to 150W, and there is no subdivision and adaptation for different lighting places, which makes it difficult for users to select models; The gap is very small, so it can only be installed in a large integral flameproof enclosure, which not only reduces the safety performance but also increases the cost, and the heat dissipation is also greatly affected; moreover, the non-modular structure makes maintenance and installation very complicated. All products need to be developed separately, resulting in duplication of research and development costs, causing a lot of waste to the enterprise
