Why are street lights not durable?
Street lights need to be lit every day, and the lighting time is relatively long. If the quality is not too hard, not only the people are not satisfied, street lamp management and maintenance is also a big task, so the street lamp requires its lighting rate is one of the key indicators. . Then, when the street lamp is first purchased, you should seize the following key links.
The first step in purchasing is the light decay test report, which is a very important part. At the time of bidding, each company will provide different units of light decay test reports, some provide their own company self-test, and some third-party testing, although the test report here is good, the actual real light decline is great, the reason Everyone knows, then how can we get to know the real thing?
The test report is first and foremost a designated agency accredited by the Semiconductor Alliance. Such as Beijing Electric Light Source Quality Supervision and Inspection Center, Shanghai Electric Light Source Quality Supervision and Inspection Center, Semiconductor Thirteen, etc., the light fade from the test reports of these units has credibility, the street lamps use high power, the heat generated, Two problems are explained by the light decay detection: the light decays and the power supply passes. If a street lamp can't pass the test in the lab, can it still guarantee the quality?
