Xishan Duerping Coal Mine uses Osram's flexible and versatile Oslon SSL series LEDs as the lighting source. Duerping Coal Mine is located in Shanxi Province, known as the “coal township†in China. The mine field area is 63.1 square kilometers. It belongs to a high-gas mine. Recently, 975 lamps with 19,500 LEDs were used to provide lighting, replacing the previous one. Traditional fluorescent lamp. LED miner's lamps not only can greatly reduce maintenance costs and accident rates, but also save 61% of energy consumption (annual power consumption from 4.2705 million watts to 17082 million watts), equivalent to annual savings of more than 220,000 yuan (about 2.8 10,000 euros) electricity expenses.
Due to low light reflectivity, low contrast, high temperature, and strong corrosion, underground coal mines have always been one of the most difficult applications for lighting. Nowadays, replacing traditional incandescent lamps with LED lamps greatly reduces the difficulty of this application.
This batch of 20W LED miner's lamps has two designs: round LED lamps are mainly used for general lighting in coal mines, and square LED lamps are mainly used for long-distance lighting in tunnels. Light reflectance in coal mines is low, so light sources with extremely high light output are required. Oslon SSL is ideal for this application with its luminous flux from 104 lm warm white light to 130 lm cool white light.
The chairman of this batch of LED coal mine lamps, Shenzhen General Technology Co., Ltd., Mr. Li Zhonghua, pointed out: "The reason why we chose Oslon SSL LEDs from Osram is mainly because of their high reliability and excellent light efficiency. More importantly, these The LED has a high light output, which can meet the design requirements. The average illuminance of the incandescent lamp used before is only 45 lx, and the average illuminance of this batch of LEDs is as high as 82 lx. With advanced optical components, we can get this contrast Reduce glare in low environments. "
In addition to high light efficiency, the application of these LED lamps can pass the rigorous test in the coal mine environment, with coal mine safety certification, explosion-proof certification, can pass the salt spray, waterproof test and 1000-hour combustion test.
Mr. Zhong Jiecong, Senior Marketing Director, Asia Region, Osram Opto Semiconductors Asia Ltd., said: "The use of LEDs as a light source in coal mine lighting is a general trend and developing rapidly. We are very pleased that China's major coal provinces can adopt Oslon SSL LEDs. They are the most compact packages on the market. 1W LED; and they do not have a fragile glass casing. We hope that the use of these LED lights can reduce the danger of underground workers. "
The LED is very strong, without fragile glass shell and easily broken filament. In addition, LEDs provide more than 50,000 hours of reliable lighting compared to incandescent bulbs with a longest service life of 3,000 hours. The maintenance interval of the miner's lamp is extended from three months to one year. According to a study by the National Institute of Occupational Safety and Health (NIOSH), the incidence of accidents during the maintenance and repair of light bulbs or lamps can be as high as 53%; the long life and safe packaging of LEDs (without glass housing) Then reduce the chance of facing these dangers.
Standard Type Disc Insulator is made of glass to support and insulate wires. Standard disc Vintage Glass Insulators are connected together for the power cord, one end is connected to the pole by fittings, and the other end is connected to a conductor or cable.
