LED fluorescent lamps will gradually appear in indoor lighting, but currently most of the domestically produced LED fluorescent lamps are exported and few are used domestically. Many issues are highlighted in this problem. The most important issue among them is the price, which has led to LED fluorescent lamps still mainly being used for commercial lighting.

Although supported by government policies, the quality of LED fluorescent lamp products still varies greatly. It's not even comparable to the lifespan of fluorescent lamps, which has a negative impact on LED lighting products and is also the reason why the civilian market for LED lighting is not optimistic.

Based on this question, we have summarized several issues for LED:

The first issue is the constant current drive of the driving power supply. Due to the difference in current between LED wicks, improper use can easily cause light decay, greatly reducing the lifespan.

Secondly, the issue of heat dissipation. Whether it is LED lights or LED displays, heat dissipation is a relatively important issue, and solving the heat dissipation problem is also a problem that LED companies must face now.

Thirdly, the instability of power modules and the issue of whether product safety certification can be passed? Due to the lack of standardized LED lighting certification requirements in China, many things need to be understood by LED companies themselves Perfect.

4、 Structure

In theory, since LED fluorescent lamps are called fluorescent lamps, their structure must be the same as that of fluorescent lamps, with the same length, thickness, and even the same names of T10, T8, T5, so there is nothing to discuss. Actually, it's not like that. LED fluorescent lamps have taken many detours in this regard, which is worth mentioning.

5、 Lifespan (control of LED junction temperature)

We know that the lifespan of low-power LED indicator lights is very long, but the issue of LED lifespan has only been raised since LED was used as a lighting device. In fact, the lifespan of an LED depends entirely on its junction temperature. As long as the junction temperature is low enough, it is not a problem to increase the lifespan of LED to over 100000 hours.

However, due to the relatively low luminous efficiency of LED itself, about 70% of the input power needs to be converted into heat energy. If this heat cannot be well dissipated, the junction temperature of LED will increase, and the lifespan of LED will decrease accordingly.

Of course, the most important factor is the price.
