A survey conducted by guangzhou original semiconductor lighting co., LTD on the lighting project of yihe experimental primary school proves that students and teachers in the school are satisfied with the lighting effect of LED lights. According to the test data of the use effect, yihe experimental primary school has saved 26,280 KWH of electric energy and 26,280 yuan of electricity cost since it put on LED lights in April this year. The emission of carbon dioxide, nitrogen oxide and sulfur dioxide has been reduced by 26.8 tons, 0.5 tons and 5.5 tons respectively. Meanwhile, the maintenance cost of lamps has been saved by 13,500 yuan.Campus classroom lighting calls for LED lampsIn 2004, guangzhou issued a letter to the ministry of science and technology proposing to promote the use of LED l...
