With the deepening of China's social openness and the promotion of human rights awareness, the safety of coal mine production and the safety of miners' lives have become a common concern of the whole society. According to the State Administration of Work Safety, between 2001 and 2004, there were 188 major coal mine accidents that killed at least 10 people, an average of one accident every 7.4 days. In 2004, there were 14 particularly major accidents with a death toll of more than 30.

Among them, 6 mining accidents, accounting for 42.8 percent. The official death toll in 2004 was 6,027. In the first half of 2005, the state allocated 3 billion yuan in special funds to upgrade coal mines' technology, and the work safety bureau was upgraded to the General Administration of work safety, but the situation remained grim, with the death toll in the first half rising 3.3 percent from a year earlier to 2,672. According to incomplete statistics, 80% of these mining accidents are directly caused by lighting.

The direct benefit of the progress of LED technology is its application in mining lamps. The emergence of LED mining lamp greatly reduces the probability of mining accident caused by the explosion of mining lamp bulb and the explosion of gas caused by underground dismantling and replacing mining lamp. 2.1 Overview of traditional mining lamps in the middle of the 18th century, Britain's industrial revolution greatly increased the demand for energy. Britain's best coal seams close to the surface have been exhausted. Coal miners have to drill shafts to reach the mining area. Deep mining has caused serious problems with methane explosions caused by the unprotected flames of candles and oil lamps.
