As a good helper for interior design, LED strips are often used to create a special atmosphere. However, with the development of intelligent lighting systems, everyone has divided on the dimming method after the LED light strip is connected.
What is the led strip?
The light strip is a kind of lamps commonly used by everyone. Generally, the light strips on the market are rolled into a disk shape, and then everyone cuts the appropriate length to use according to actual needs.
LED lights with dimming can only be used to adjust the supply voltage. There are two main ways to achieve this: 1. thyristor tangential voltage regulation, 2. sine wave voltage regulation.
Generally, we use an autotransformer to test the voltage regulation effect of a sine wave, because the autotransformer can adjust the voltage, and the output is a sine wave alternating current.
Application scene of led strip
Nowadays, many companies and enterprises follow the modernist interior style route, with naked and simple clothes everywhere. The led engineering light strip is embedded in the bare ceiling and hidden in the gap of the counter, emitting cold light, which makes the company a professional and efficient image.
LED engineering light strips are often used in restaurants, and they all play a very important decorative effect. This restaurant is dominated by yellow light. In the lobby, the light strip is not the main light source, but it is hidden in the gap between the corners of the wall.
Through experiments, we can find that with an autotransformer, which is a sine wave voltage regulator, the working power of the LED light strip can be greater.
In addition, we will find that the use of sine wave voltage to adjust the brightness of the led strip is smoother, and the thyristor voltage adjustment process can obviously feel the light and dark beating gap.
Thyristor tangential voltage regulation
Thyristor tangential voltage regulation is to change the waveform of the motor terminal voltage by changing the conduction angle of the thyristor, thereby changing the effective value of the motor terminal voltage to achieve the purpose of voltage regulation.
There are actually two types of thyristor dimming, Triac dimming is also called leading-edge phase-cut dimming, and the other is inverting control dimmer (that is, trailing-edge phase-cut dimmer). ELV dimming. In theory, trailing edge dimming is more suitable for LED light dimming.
