Broadly applicable for fixed lighting in underground coal mine galleries and tunnels with explosive mixtures of methane, coal dust, etc. The DGS24/127L(A) tunnel light is a newly developed explosion-proof LED tunnel light by our company, which meets the national standards and industry standards of GB3836.1-2000 and GB3836.2-2000 for electrical equipment used in explosive gas environments. It is mainly suitable for places with explosion hazards due to gas and dust in coal mine tunnels, comprehensive mining work faces, caverns, substation transformer rooms, pump houses, underground parking lots, and other locations requiring fixed lighting. This lighting fixture features an integrated structure, with both the light source and drive power supply installed within the fixture body, offering an aesthetically pleasing design, compact structure, shock and vibration resistance, heat resistance, good sealing, water resistance, and easy installation and use. The light source utilizes advanced high-quality LED technology, consuming low power, saving energy, generating minimal heat, and boasting a long lifespan of 4 to 5 years without the need for replacement or maintenance, thereby solving the issue of frequent bulb changes in older lighting models. With high luminous efficiency, the brightness of 18W is equivalent to that of a 100W to 200W traditional tunnel light, and it is environmentally friendly.
