Nowadays, Osram LED Lights are widely used in many field, such as residential lighting, automobile lighting, industrial lighting, etc. Recently, Osram began to be used in mining field replacing fluorescent lamps, which has saved needs for maintenance of fluorescent lamps, and reduced the accident rate. Also in this way, we can save about 28,000 euros.
With low reflectance of light, low contrast, high temperature, highly corrosive, underground coal mining has always been one of the most difficult lighting applications. Now with LED replacing the traditional incandescent lamps, it greatly reduces the challenge of this application. There are two different designs of the 20-watt LED lights. Round LED lamps are used as underground coal mining areas of general lighting, while square LED lights are used in the tunnel of long distance illumination. Mining is extremely low reflectance field, requiring high light output light source. In addition to high-efficiency, these LED lighting can be used in the rigors of the environment of the coal mining, which has coal mining safety certification, explosion-proof certification, by fog and water testing and 1,000 hours of combustion testing.
Zhongjie Cong, OSRAM Opto Semiconductors Asia Ltd. Senior Marketing Director in Asia said: “LED lighting is taking off in coal mining, and the rapid development. It is our honor that Osram is eligible for using in the coal city of province of China. It is the most compact of the market. We look forward to reducing the chance of risk by using these LED lights for people working in the ground. “
LED is very solid, because they are enclosure and do not have fragile filaments. In addition, in comparison, the service life of incandescent bulbs is only 3,000 hours, while LED can provide more than 50,000 hours of reliable light and the maintenance period also extends from three months to once a year. According to the US National Institute for Occupational Safety and Health (National Institute for Occupational Safety and Health, referred NIOSH) studies, it have shown that the probability of the accident occurrence during the bulb or lighting maintenance during maintenance is up to 53%. Thus, LED possess longer life and safety package (no glass shell) feature, reducing the chance of worker exposure in danger.
