Explosion proof LED roadway light DGS18/127L (A) for coal mines, high brightness energy-saving explosion-proof lighting

Description :

  DGS18/127L (A) Explosion proof LED roadway light for coal mines is a fixed lighting device designed specifically for hazardous environments such as underground tunnels and chambers in coal mines. This product mainly solves the safety lighting problems in damp, dusty, and explosive gas environments underground, and is suitable for underground tunnels and chambers in coal mines with methane and coal dust explosion hazards. As a representative of intrinsically safe or explosion-proof lighting fixtures for mining, DGS18/127L (A) coal mine explosion-proof LED roadway lights use high-efficiency LED light sources, which have the characteristics of small size, light weight, long service life, and maintenance free. They can effectively reduce the labor intensity of miners and improve the safety of underground operations.

  The casing of DGS18/127L (A) explosion-proof LED tunnel lights used in coal mines is usually made of high-strength aluminum alloy die-casting, and the surface is treated with high-voltage electrostatic spraying, which has good anti-corrosion and rust prevention properties. The internal circuit design of the lamp is reasonable, and the heat dissipation structure is optimized to ensure that the temperature of the LED chip is controlled within a safe range under long-term operation. Its electrical parameters comply with MT/T standards, with a rated voltage of AC127V, a power of 18W, high luminous efficiency, and good color rendering index. The protection level reaches IP65 or above, which can prevent dust from entering and water from spraying in all directions from entering, and adapt to harsh underground environments. DGS18/127L (A) Explosion proof LED tunnel lights for coal mines strictly comply with national coal mine safety standards and have passed relevant explosion-proof certifications.

  When selecting, it is necessary to clarify that DGS18/127L (A) explosion-proof LED tunnel lights for coal mines are suitable for power supply networks with AC 50Hz and voltage of 127V. If the voltage level underground is different, corresponding transformers need to be equipped. This lighting fixture is different from ordinary industrial LED lights and must have coal mine specific explosion-proof markings such as Exd I Mb or Exib I Mb. For main transportation tunnels with high illumination requirements, installation density can be appropriately increased or higher power models can be selected; For pedestrian walkways, this 18W specification is sufficient to meet basic lighting needs. The DGS18/127L (A) explosion-proof LED roadway lights for coal mines are mainly used in specific areas underground corresponding to Zone 1 or Zone 2 of explosive gas environments, with a focus on distinguishing the applicable areas between explosive and increased safety types.

  When installing DGS18/127L (A) explosion-proof LED tunnel lights for coal mines, it is necessary to ensure that the hooks or brackets are firm and reliable to avoid vibration causing detachment. When wiring, it is necessary to strictly follow the instructions to ensure that the introduction device is well sealed and prevent explosion. In daily maintenance, coal dust and dirt on the surface of the lampshade should be regularly cleaned to maintain transparency and heat dissipation. Check if there are cracks or deformations in the casing, and if the fasteners are loose. If obvious light attenuation or flickering is found in the LED light source, the module should be replaced in a timely manner. It is strictly prohibited to open the cover plate of the lighting fixture for maintenance while it is live underground. Proper use and maintenance of DGS18/127L (A) explosion-proof LED tunnel lights for coal mines can extend their service life and ensure the stable operation of underground lighting systems.
