Shenzhen General Technology Co. Ltd, a professional lighting company specializing research, manufacturing and sales of all kinds of outdoor lighting products based in Shenzhen, China, has applied Osram’s versatile Oslon SSL series in coal mine lighting to reduce energy, maintenance and accidents.
 
“We have chosen Osram’s Oslon SSL LEDs for their high reliability and efficiency,” said Zhong-hua Li, Chairman of the Board of Shenzhen General Technology. “More importantly, the light output of these LEDs is high enough for good designs. The average luminance is 82Lx, compared to 45Lx of the previous incandescent lamps. With the use of advance optics, we are able to reduce glare to a minimum in this low contrast environment.”
 
Apart from high efficiency, these Oslon SSL LEDs excel in all the stringent tests for applications in the coal mine environment. They include the coal mine safety certification, explosion-proof certification, salt spray, waterproof testing, impact test and the 1000-hour burning test.
