LED street lamps are currently one of the key implementation methods of energy saving and carbon reduction. Countries around the world have been in full swing to replace the original traditional street lamps with LED street lamps, and the new streets directly restrict the use of LED street lamps to save energy. At present, the market scale of LED street lamps in the world is about 90million. The light source of LED lamps is different from traditional mercury lamps or high-pressure sodium lamps in terms of calorific value, service life, output spectrum, output illumination and material characteristics. The test conditions and test methods of LED street lamps are different from those of traditional lamps. Guangdong Hongzhan Technology Co., Ltd. sorts out the reliability test methods related to LED street lamps collected at present for your reference. I hope it can be helpful and understanding for you in the application of LED related tests.
