LED tube faced several problems in the application
LED tube lights will gradually appear in the interior lighting, but most of the domestic production of LED tube export and domestic use of the very few. In this issue highlights the many problems. One of the most important is the price, resulting in LED tube or mainly in commercial lighting.

With the support of government policies, LED tube product quality or good and bad. A little even the life of fluorescent lamps are not as good, and also LED lighting products a negative impact on the civilian market for LED lighting is not promising.

This problem, we LEDs summarizes a few questions:

First, the constant current drive of the drive power. The difference between the current in the LED wick different, improper use and likely to cause the light fades, life greatly reduce short.

Second, the heat dissipation problem. LED lights or LED display, heat is a more important issue to solve the problem of heat dissipation problem is now the LED business must face.

Third, the instability of the power module and product safety certification can be passed? LED lighting now our country has not introduced a standard certification requirements, so many things are LED companies to understand and improve.

Fourth, the structure

Ordinarily, LED tube light since known as the fluorescent then its structure must be fluorescent look like, even the length, thickness, are the same, and even called the T10, T8, T5 are also what can be discussed. In fact do not. LED tube light to go in this regard a lot of detours, is worth in letters.

Fifth, life (LED junction temperature control)

We know that the very long life of low-power LED indicator, LED life span of the problem was raised only when the LED as a lighting device. In fact, the life of the LED depends on its junction temperature. As long as the junction temperature is low enough, the LED life of up to 100,000 hours or more is no problem. However, due to the luminous efficiency of the LED itself is still relatively low, there are still about 70% of the input power converted to heat energy, heat can not be distributed out of the LED junction temperature will rise, so the life of the LED will decreases.

Of course there are the most important is the price factor.
