DGS100/127L (A) Mine Explosion proof LED Tunnel Light Underground Lighting Explosion proof Lamp

Description :

  DGS100/127L (A) Mine Explosion proof LED Tunnel Light is an efficient lighting device designed specifically for hazardous environments such as underground tunnels and chambers in coal mines and non coal mines. The core of the explosion-proof LED tunnel light used in this mine solves the safety lighting problems under harsh working conditions such as humidity, high dust, and gas accumulation underground. The explosion-proof shell design prevents internal electric sparks from igniting external explosive gases, ensuring operational safety. Typical applications include mining faces, transportation tunnels, return air tunnels, and other areas, providing stable, flicker free green light sources that meet the strict requirements of the "Coal Mine Safety Regulations" for lighting equipment. It is one of the infrastructure for modern mine construction.

  The explosion-proof LED tunnel 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 good anti-corrosion, rust proof and heat dissipation performance. The light source uses high brightness and long-life LED chips, which have high light efficiency and low energy consumption. The implementation standards comply with GB3836.1-2010 "Explosive Atmosphere Part 1: General Requirements for Equipment" and GB3836.2-2010 "Explosive Atmosphere Part 2: Equipment Protected by Explosion proof Enclosures". The rated voltage is usually AC127V, with a protection level of IP65 or above, and can withstand underground water spraying and high concentration dust erosion. The lamp structure is compact, and the transparent parts are made of tempered glass with high impact resistance, ensuring long-term stable operation under complex geological conditions.

  When selecting DGS100/127L (A) mine explosion-proof LED tunnel lights, it is important to confirm that the power supply voltage level (such as 127V) matches the on-site power grid, and verify whether the gas level of the installation environment is suitable for Class I explosion-proof equipment. Unlike explosion-proof lamps used in ordinary factories, this mining explosion-proof LED tunnel lamp must have coal safety certification (MA mark), and is strictly prohibited from being excessively configured in ordinary industrial places without gas explosion hazards, nor can it be used in environments higher than its explosion-proof level. If the space in the alley is narrow, attention should be paid to the installation size and beam angle of the lighting fixtures, and a reasonable light distribution model should be selected to avoid blind spots in the lighting. For scenarios that require long-distance power transmission, the impact of line voltage drop on the start-up and brightness of lighting fixtures also needs to be considered.

  When installing DGS100/127L (A) mine explosion-proof LED tunnel lights, it is necessary to ensure reliable grounding and tighten the fastening bolts to prevent the explosion-proof surface gap from exceeding the standard. In daily maintenance, coal dust and dirt on the surface of the lighting fixtures should be regularly cleaned to maintain transparency and avoid heat accumulation affecting the lifespan of the LED. Check if the sealing ring of the introduction device is aging to prevent water and moisture from entering. Common faults include light source attenuation or damage to the driving power supply. In this case, a professional electrician should open the cover for maintenance after power failure, and live operation is strictly prohibited. It is recommended to establish a regular inspection system and replace the casing immediately if cracks, deformations, or explosions are found, in order to ensure the continuity and safety of the underground lighting system.
