Mining explosion-proof LED bracket light DGC18/127LA underground roadway lighting fixture

Description :

  DGC18/127LA mining explosion-proof LED bracket light is a fixed lighting equipment designed specifically for flammable and explosive hazardous areas such as coal mines and non coal mines. This product mainly solves the problems of high energy consumption, short lifespan, and frequent maintenance of traditional mining lamps, and is suitable for daily lighting and emergency auxiliary lighting in underground tunnels, chambers, comprehensive mining workfaces, and other environments. As a typical mining electrical product, its core function is to provide efficient and stable green light sources while ensuring absolute explosion-proof safety, meeting the strict requirements of the Coal Mine Safety Regulations and electrical equipment, and ensuring visual clarity and production safety for operators.

  The explosion-proof LED bracket light used in this mine adopts a high-strength aluminum alloy die-casting shell, and the surface is treated with high-voltage electrostatic spraying, which has excellent anti-corrosion, rust proof and impact resistance performance. The lamp integrates efficient LED light source modules internally, combined with professional optical lenses, to achieve uniform distribution of light without glare. The electrical cavity and light source cavity are designed independently, and the heat dissipation structure has been optimized to effectively reduce junction temperature and extend device life. The product complies with the GB3836 series electrical equipment standards for explosive environments, with a protection level typically reaching IP65 or above. It can adapt to harsh working conditions such as humidity and high dust underground, ensuring stable operation at a rated voltage of 127V. The insulation resistance and dielectric strength meet the requirements of the mining product safety mark certification.

  In the selection and application, it is necessary to clarify that DGC18/127LA mining explosion-proof LED bracket lights are suitable for mine environments with gas and coal dust explosion hazards, with a voltage level of 127V AC. When purchasing, it is necessary to distinguish the installation method. This model is usually bracket or wall mounted, suitable for fixing on the side wall or roof of the roadway. Unlike ordinary factory explosion-proof lamps, this product must have a valid mining product safety mark certificate (MA certification). If the usage environment is a non mining chemical plant, it is necessary to confirm whether it is compatible with the corresponding gas and temperature groups. For long-distance roadway lighting, it is recommended to determine the installation spacing based on illuminance calculation to avoid blind spots in lighting. At the same time, attention should be paid to matching the sealing ring of the cable introduction device to ensure that the inlet diameter is consistent with the actual cable outer diameter.

  When installing DGC18/127LA mining explosion-proof LED bracket lights, it is strictly prohibited to open the cover with power on, and the operating procedures of "power-off, power testing, and discharge" must be strictly followed. In daily maintenance, coal dust and dirt on the surface of the lighting fixtures should be regularly cleaned to maintain good heat dissipation and light transmittance. Check if there are cracks or deformations in the shell, if the fasteners are loose, and if the grounding device is reliably connected. If severe LED light decay or driver power failure is found, professional electricians should replace the same specification spare parts, and internal circuits should not be changed or non original accessories replaced at will. Before resuming use after long-term disuse, the insulation resistance needs to be measured and confirmed to be qualified before power can be transmitted to ensure continuous and reliable underground lighting support.
