LED fluorescent lamps will gradually appear in indoor lighting, but now most of the domestically produced LED fluorescent lamps are exported, and very few are used in China. Many problems have been highlighted in this issue. One of the most important is the price issue, leading to the current LED fluorescent lamps are still mainly commercial lighting.

Despite the support of government policies, the quality of LED fluorescent lamps is still mixed. Even the life span of fluorescent lamps is not as good as that, which also has a negative impact on LED lighting products, which is also the reason why the LED lighting civilian market is not optimistic.

According to this question, our LED summarized several questions:

First, the constant current driving problem of the driving power supply. Because the current difference between the LED wicks is different, improper use can easily cause light decay and greatly shorten the life span.

Second, the problem of heat dissipation. Regardless of whether it is an LED lamp or an LED display, heat dissipation is a relatively important issue, and solving the heat dissipation problem is also a problem that LED companies must face now.

Third, the instability of the power module and the question of whether the product safety certification can be passed? Since my country has not yet issued a standard LED lighting certification requirements, so many things need to be understood and perfected by LED companies themselves.

Four, structure

Ordinarily, since the LED fluorescent lamp is called a fluorescent lamp, its structure must be the appearance of a fluorescent lamp, even the length and thickness are the same, even the title is T10, T8, T5, and they are all the same, so there is nothing to discuss. In fact, it is not. LED fluorescent lamps have taken a lot of detours in this regard, which is worthy of special mention.

5. Life (control of LED junction temperature)

We know that the lifespan of low-power LED indicators is very long, and only when LEDs are used as lighting devices, the lifespan of LEDs has been raised. In fact, the life of an LED depends entirely on its junction temperature. As long as the junction temperature is low enough, there is no problem in increasing the lifetime of the LED to more than 100,000 hours.

However, because the luminous efficiency of the LED itself is still relatively low, about 70% of the input power has to be converted into heat energy. If the heat cannot be dissipated well, the junction temperature of the LED will increase, and the life of the LED will be reduced. It decreases accordingly.

Of course, the most important factor is price.
