A miner's lamp is a portable lighting device used by miners to illuminate dark underground environments. Traditionally, these lamps used oil or gas, but modern versions often utilize batteries and LED technology. The design ensures safety by minimizing the risk of igniting flammable gases commonly found in mines. One of the most famous types of miner's lamps is the Davy lamp, invented by Sir Humphry Davy in 1815. This lamp features a mesh screen that prevents flames from escaping, reducing the risk of explosions. Miner's lamps have played a crucial role in enhancing safety and productivity in the mining industry.
