Specializing in R&D and production of LED optoelectronic products and visual inspection instruments
1. Product Features
●The power saving effect is obvious: in the case of the same brightness, it saves 90% of electricity than ordinary incandescent lamps and 65% of energy than energy-saving lamps.
●Long lifespan: The average lifespan of the LED light source can reach 50,000 hours, avoiding frequent replacement of bulbs or lamps and achieving maintenance-free.
●Environmental protection: no pollution, no ultraviolet radiation, is a new generation of green lighting.
Wide working voltage range: the voltage changes in the range of 85-240V, the lamps work normally, and the brightness does not change.
It effectively solves the problem of lamps that are easy to burn due to large voltage fluctuations in the well.
●The product took the lead in researching a new generation of heat conduction structure, and the lamps achieved good heat conduction effect.
2. Main purpose and scope of application
Main application: It is used for safety lighting in flammable and explosive environments such as gas and coal dust underground in coal mines, and can also be used for lighting in chemical, cement plants, flour mills and other places.
Scope of application: It is suitable for the lighting of all the alleys, chambers, underground parking lots and other places in the coal mine.
3, the use of environmental conditions
1) Ambient temperature: -20℃～+60℃;
2) The relative humidity of the air is less than or equal to 95% (+25°C);
3) It is suitable for places where there is a danger of gas and coal dust explosions in coal mines.
4. Safety requirements
1) Product explosion-proof type: This product adopts explosion-proof type, and the explosion-proof mark is: ExdⅠ
2) This product is equipped with a safety warning sign, and live operation is strictly prohibited.
3) It is strictly forbidden to disassemble the miner's lamp or replace the parts in the underground, and the maintenance and repair of the miner's lamp must be carried out on the ground;
4) It is strictly forbidden for non-professionals to maintain and repair miner's lamps;
2. Structural characteristics and working principle
1. Structural features: The roadway light is composed of power supply cavity, transparent tube cover, light source body, back cover and other components.
2. Working principle
The roadway light adopts LED light source, AC 127V input voltage, and explosion-proof lamp structure. After the lamp is assembled and installed, turn on the power supply, the LED light source will light up, and the lamp will work.
