(Summary description) 　　Coal mine led roadway light is a new generation of semiconductor luminescent cold light source device, which has the characteristics of power saving, long life, convenient maintenance, high brightness, and light can be concentrated or dispersed. The lamps with concentrated light have a long irradiation distance, and are especially suitable for lighting in tunnels, shunting sites, substations, water pump winches and other places. 　　 performance and structure The explosion-proof LED roadway lights are used for li, and the light source adopts high-efficiency, energy-saving and environmentally friendly high-lumen high-power LEDs. The LED is packaged with imported high-brightness chips, and the light efficiency is as high as 100Lm/W. Strong shock resistance, strong dustproof performance, low energy consumption, small voltage and current required, low heat, less luminous heat, no potential safety hazards, high safety factor, LED lighting belongs to solid light source, epoxy resin encapsulation, the luminous body part is not easy Loose, the service life can reach 30,000 to 50,000 hours, which is 30 times that of ordinary light bulbs, which is equivalent to three years of uninterrupted lighting. Continuous use without replacement, maintenance-free. The shell is formed by die-casting aluminum, the surface is electrostatically sprayed with powder, the high temperature resistant silicone rubber sealing ring and tempered light-transmitting glass are featured with explosion-proof, waterproof, impact resistance and vibration resistance. -Integrated design, unique design, beautiful appearance, good heat dissipation. Built-in high-quality switching power supply, wide operating voltage range, low operating temperature, maintenance-free. The integrated LED light source is fixed on the aluminum heat sink with screws, and is bonded and packaged with silicone with better thermal conductivity. Conducting the working heat of the LED light source to the shell to increase air convection cooling, to achieve the effect of reducing the temperature of the mine explosion-proof LED roadway light and the LED junction temperature, thereby improving the light efficiency and prolonging the service life of the mine explosion-proof LED roadway light . The transparent lampshade and protective cover mainly protect the LED light source from being damaged by external force. The transparent lampshade can withstand an impact energy of 4J when protected by a protective mesh cover. The shield grid is less than 50mmx 50mm. 　　 Use environment: Ambient humidity: -5C~+40C. The air pressure is 0.8-1.1 x 10'PA and the altitude is 2000m. The monthly average relative humidity of the surrounding air is not more than 95%. Can be used in places where there is a danger of gas and coal dust explosions. The pollution level is three in other or steam environments without damaging the insulation. 　　The above is the introduction of the editor, I hope it will be helpful for everyone to understand the led roadway lights in coal mines.
