subject: Led Fluorescent Lamp In The Application In The Face Of Several Problems [print this page] LED fluorescent lamp will gradually appear in the interior lighting, but now most of the domestic production of LED fluorescent lamp is export ,and domestic use very few. In this issue it highlights a lot of problems. One of the most important is the question of price, which result LED fluorescent lamp is given priority to commercial lighting.
Although there is a government policy support, the LED fluorescent lamp product quality or the good and bad are intermingled. Even a little fluorescent lamp lifetime is not worth, so that also give LED lighting products brought negative influence, but also LED lighting civilian market is not optimistic about the reason for it..
According to this problem, we LED summarizes a few questions:
The first is the drive power constant current drive problem. Because of the difference between LED wick current value is different, undeserved use is easy to cause light failure, make it lifetime greatly shorten.
The second is the heat dissipation problems. Whether the LED lights or LED display, heat dissipation is a more important problem, so solves the heat dissipation problem is now LED companies must face problems.
The third, power module instability and product safety certification whether it can through the problem? Since the present our country has not introduced the standard LED lighting certification requirements, so a lot of things are need LED enterprises itself to understand , Perfect.
The fourth is the structural problem. Ordinarily, LED fluorescent lamp since called as fluorescent light then its structure must be fluorescent lamp appearance, even the length, the thickness of the same, or even call is T10, T8, T5, also are the same, also there is nothing to discuss. In fact it is not. LED fluorescent in this regard take a lot of detours, is worth in letters.
The fifth is the life (LED junction temperature control) problem. We know that the life of the small power LED indicator is very long, just when the LED as a lighting device since, the LED lifetime of the problem just only proposed to. In fact, LED life totally depends on its junction temperature. As long as the junction temperature is low enough, LED's life increase to more than 100,000 hours is no problem.
But because of itself LED luminous efficiency is still relatively low, about 70% of the input power to into heat energy, if these hot can not very well dissipated, LED junction temperature will rise, and then the LED life will decrease. Of course, there is the main factor is the price factor.
