LED tube will gradually appear in indoor lighting, but now the domestic production LED tube mostly is export, only a few is domestic use. In this problem, a lot of problems is highlighted. The most important issue is the price, which result LED lamp now major is commercial lighting based.
1, drive power constant current problem. Because the current between the LED wicks is different, improper use is likely to cause the light fades, so that greatly reduce the life span.
2, Heat dissipation, whether LED lights or LED display, heat dissipation is a more important problem, the heat dissipation problem is now the LED enterprises must face.
3, the power module instability and product safety certification problem, now because our country has not issued a LED lighting certification requirements standard, so many things are needed LED manufactures to understand, perfect.
4, Structure, supposedly, LED tube so called since its structure should be certain fluorescent appearance, even length, thickness are the same, and even call also T8, T5, there is no discussion can be. In fact, it is not. LED tube in this area has take a lot of detours, is worthy of letters.
5, life, we know that low-power LED lights life is very long, but when the LED is used as a lighting device since, LED life problem was raised. In fact, it depends entirely on the life of the LED junction temperature. As long as the junction temperature low enough, LED’s life expectancy increased to more than one hundred thousand hours is not a problem.
