How long is the life of LED lamp in the end? It may be the most difficult issue to make clear for the current lighting industry. Most of the LED lighting company propaganda that the life of LED light source is more than 50,000 hours, which indeed is only theoretical calculations. The life of Straw hat and closed Piranha LED light can be said clearly, the life of 3528MT closure LED can be made sure, because their life is not so long, we can get the results after they are used in laboratory for two or three years, but we can’t make sure how long is the life of the 1-3W high-power light sources, CREE and OSRAM has done 30,000 hours , the light fades is still below 30%, it is estimated that the life of the light source (light fades 30%) is 50,000 hours, which is pretty similar. But how long would be suitable for LED life in the end? LED expert view is that we should design different life in different situations. LED tunnel lights and LED flood light and other high power lighting that is used in occasions (tunnels, underground garage, etc.) where the daily illumination time is 18 hours or more should need 50,000 hours of life, and the life of 30,000 hours is enough for road lighting, which would mean that the life of LED road lights should be defined as year , we can predict that some LED road lights that are just installed would be broken in three years, because the light efficiency of LED street lamps will exceed 150LM / W after three years, which is twice higher that current, the higher luminous efficiency is, the worse quality of the light is,at that time it must be replaced, either for LED tube that light up for 8-10 hours a day lights, the total life is 20,000 hours! |
