This mine-specific explosion-proof floodlight has a range of professional features tailored to underground coal mine environments. First, its Exd I Mb flameproof certification ensures that even if an internal fault occurs, Second, LED chip with a luminous efficacy of 110lm/W provides uniform, glare-free lighting, reducing visual fatigue for miners and improving work efficiency in long-hour underground operations. Third, the double-layer heat dissipation structure, combining cast steel shell and internal heat pipes, effectively dissipates heat generated by the LED, maintaining a low junction temperature and extending the light source life. Additionally, the product is equipped with a shock-resistant lamp cover made of 10mm thick tempered glass, which can withstand impact from falling rocks with a weight of up to 5kg. It also supports dimming and remote control functions, allowing underground operators to adjust brightness according to different working scenarios, further saving energy. Unlike traditional mine lamps, this product does not contain mercury or other harmful substances, making it environmentally friendly and easy to dispose of.
In terms of technical specifications, this underground mine explosion-proof light has a product size of 450mm×380mm×150mm (L×W×H) and a net weight of 12.5kg, ensuring stability in harsh underground environments. It operates on an AC voltage range of 127V/220V, which is compatible with the standard power supply system in coal mines. The ensuring clear identification of rock layers, mining equipment, and safety signs in dim underground conditions. The flameproof enclosure has a joint gap of ≤0.3mm, meeting the Exd I Mb standard for mine flameproof equipment. The product has an ingress protection grade of IP68, meaning it can be immersed in water up to 1.5 meters deep for 30 minutes without water ingress, suitable for use in water-filled tunnels. It also complies with GB3836.1-2010, GB3836.2-2010, and MT928-2006 mine lighting standards, ensuring compliance with national mine safety regulations. The product is equipped with a 2m high-temperature resistant rubber cable, which is resistant to oil, abrasion, and corrosion, suitable for long-term use in underground environments with high humidity and mechanical wear.
This flameproof LED floodlight is exclusively designed for underground coal mine operations, covering a wide range of application scenarios. In mining faces, and transportation operations, ensuring miners can clearly see the working surface and avoid potential safety hazards such as rock falls and equipment malfunctions. In underground tunnels and haulage roads, it illuminates the entire road surface, improving the safety of locomotive transportation and pedestrian travel. It is also suitable for underground pumping stations and power distribution rooms, providing stable lighting for equipment maintenance and operation. For deep mines with high temperatures and high humidity, its wide operating temperature range (-40℃~+80℃) and IP68 protection grade ensure continuous, reliable performance. Additionally, it can be used in metal mines with flammable dust environments, such as iron ore and copper ore mines, as long as the explosion-proof requirements are met. This product is a key equipment for mining enterprises to improve underground safety and production efficiency, helping to reduce accident rates and lower long-term operation costs. It is also an essential part of mine safety transformation and upgrading projects, meeting the requirements of modern green mining.
