Anti-explosion type narrow light distribution LED tunnel lamp

Abstract

The invention discloses an anti-explosion type narrow light distribution LED tunnel lamp. The LED tunnel lamp comprises a lamp casing and an LED light source unit, wherein the lamp casing comprises a top cover, an upper casing component, a middle casing component, a lower casing component and a protective mesh; the top cover and the upper casing component are fixed by adopting a planar anti-explosion way, the upper casing component and the middle casing component are fixed by adopting a cylindrical anti-explosion way, and the middle casing and the lower casing are fixed are fixed via the planar junction surface of a hole, which is outside the casing; the lower casing component is provided with a lower casing main body and a transparent piece, and the protective mesh is fixedly arranged outside the transparent piece; the LED light source unit is fixed on the middle casing component, and comprises a lamp main body in the shape of a trapezoid body, a first LED lamp light source and a second LED light source; and the first LED light source and the second LED light source are respectively arranged on the two opposite side surfaces of the trapezoid body. According to the invention, the light utilization rate can reach 100 percent at most, and in addition, the structural anti-explosion effect is good and can synchronously satisfy the first-class and second-class anti-explosion requirements of the National Anti-explosion Standard.

Description

Technical field [0001] The invention relates to a lighting device, in particular to an explosion-proof, narrow and long light distribution LED roadway lamp. Background technique [0002] In the prior art, explosion-proof roadway lights are generally composed of metal halide light sources, supporting ballasts, triggers, capacitors, and explosion-proof housings. They are integrated lamps, but they do not have an isolating switch and do not meet the new national standard GB 3836.1- 2010 requirements. Of course, it cannot pass the safety standard certification and cannot be used in the tunnels in the coal mine; figure 1 It can be seen that when the explosion-proof roadway lamp 101 is working, no light can be projected directly below, that is, there is a dark area 104, and the light in the area 102 and the area 103 is projected into the space, and the light utilization rate is low. [0003] Therefore, the prior art has defects and needs to be improved. Summary of the invention [0004]...
