In the current field of LED lighting, most manufacturers use thyristor dimming to achieve dimming. Although thyristor dimming technology is the mainstream, it does not mean that it is perfect. At present, there are still some shortcomings in thyristor dimming, so the promotion of compatible thyristor dimming LED lighting equipment in the market still has It must be difficult. The advantages of thyristor technology have been introduced to you a lot, this article will not go into details, but to introduce the shortcomings of the current compatible thyristor dimming.
The reasons why the current compatible thyristor lighting is still limited in the market include the following aspects.
The development of thyristor technology has been an old technology with more than half a century. It has many of the shortcomings mentioned above and is a technology that should have been eliminated. Social development requires a more advanced and intelligent product to replace it.
Currently compatible with thyristor dimming LED driver ICs, many claim to have PFC, can achieve higher power factor, in fact it only improves the power factor of the load, making the overall circuit look closer to pure resistance, but actually There is no improvement in the power factor of the entire system including the thyristor.
As mentioned above, in order to keep the thyristor's holding current insufficient, many thyristor-compatible LED dimming systems require an additional bleeder resistor to increase the loss, making the overall efficiency of the LED dimming system very low. The original intention of completely damaging the high energy efficiency of the LED.
In addition, the current market development of thyristor dimming LED systems is uneven, and the LED drivers that are completely compatible with all thyristor dimmers are basically not available, which inevitably adds a lot of development tasks. In addition, LED drivers that truly match all thyristor dimmers have yet to be verified for long periods of time.
The proportion of incandescent and halogen lamps installed with thyristor dimming is less than one in ten thousand, while the proportion of thyristor switches installed in the wall is not more than one in ten thousand in thyristor dimming lamps. To, because most of the installation of thyristor dimming are table lamps, bedside lamps, standing lamps. What's more, there are dozens of different types of thyristor and transistor dimmer switches on the market. In fact, the developed ICs are not compatible with all thyristors, but only a small part of them.
LED is a brand new Genesis technology with unparalleled superiority. In the face of the increasingly mature market demand for dimmable LED lighting products, the development of thyristor dimming LED drivers needs to be carried out in a sustained manner.
The advantage of traditional thyristor dimming is that its foundation in the incandescent lamp market makes it very easy for consumers to accept. However, LED thyristor technology has incomparable advantages in terms of cost and dimming. It is believed that with the advancement of LED technology , more and more people will choose to use LED thyristor lighting.
