This product is suitable for underground coal mines with explosive gas mixture of methane and coal dust as lighting and signal indication in underground working areas such as transportation machinery, various trackless rubber-tired vehicles, drilling rigs, tunneling machinery and battery electric locomotives. 1. The LED light source radiator is formed by cold forging of aviation aluminum, which has the characteristics of light weight and fast heat conduction; 2. After the shell is cast with high-quality steel, the surface is treated with plastic spraying; 3. The transparent parts are made of high borosilicate material. Tempered treatment, light transmittance up to 95%, strong impact resistance and corrosion resistance; 4. The LED light source adopts international brands, with high luminous efficiency, aging resistance, energy saving and environmental protection; 5. The LED driver adopts wide voltage, constant current design, stable power No attenuation, no stroboscopic, and has the functions of overload, short circuit, high temperature self-protection; 6. The lens adopts the integrated structure of the reflector cup, and after the secondary optical science distribution, the light concentration is strong and the irradiation distance is long. 7. The lamp body is fixed by a movable steel bracket, which can flexibly match the installation requirements of various specifications of locomotives.
