LED light lamp beads 1.LED lamp life Many LED lighting manufacturers conceal the life, even on the color page of their product catalog, at the nonsensical: casually LED lighting product life can be up to 100,000 hours, or even 150,000, 20 million hours. This is indeed a lot. |
2. the light decay of LED lamp beads As the LED light up, P / N junction and the entire device is immediately aged due to high temperature, so that the luminous efficiency will be gradually reduced, which is a normal phenomenon, and there are so few the factors that affect the LED light failure: ?, the use of inferior LED lamp, the packaging process of the LED lamp beads is flawed, chip cooling can not well be exported from the PIN feet, resulting in that the excessive die temperature makes the chip attenuation is intensified. Brightness decay rapidly. ?, LED constant current driver, there are some LED voltage lead to the LED attenuation. ?, drive current is greater than the rated drive.
If the bottom glue and the white glue of LED lamp is made of poor epoxy resin and the LED lamp beads packaged by the packaging glue, the single light up at 30 degrees, after 1000 hours, the attenuation data is 70% of the light fades, while the light volume will be drastically reduced after the lamp beads is decayed 70%,. Currently the latest international standards infinite the node that the light of the LED lamps is 70%. The ordinary SMD fades of the LED tube light manufactured by the regular large brands is generally is within 5% in 1000 hours.
However,there are still a large number of excellent manufacturer engaging in manufacturing and researching the LED light,of which the lead lighting is just one,lead Lighting adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light, which fully guaranteed stability and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while the low voltage constant current driver convert the AC into DC so that improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is famous for energy-saving and environmental protection ,login www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.
