Furthermore, RGB LEDs have better color control flexibility than white LEDs, and the color gamut is also increased by a factor of about 1.5.

The silicon controlled rectifier dimmer is fixedly arranged on the LED driving chip 8 and is electrically connected with the LED light source 4 through the LED driving chip 8.

The specific model of the silicon controlled dimmer is MP4033, and MP4033 is TRIAC dimmable and 0-10V dimmable with active PFC function, primary side control and offline LED lighting controller. It can output an accurate LED current for isolated lighting applications of single stage converters. A proprietary real-time current control method can be used to accurately control the LED output current based on the primary information. The LED lighting system design can be made simpler because an auxiliary side feedback circuit and optocoupler are not required.

MP4033 implements power factor correction and operates in a boundary conduction mode to reduce MOSFET switching losses; MP4033 has an integrated charging circuit on the power pin for quick start-up, but no noticeable delay.

By applying the specific real-time current control method of the chip MP4033, the LED current can be accurately controlled by using information, the working efficiency and stability of the LED lamp are improved, and the energy consumption is reduced

When the utility model is used, the output current waveform of the circuit is detected by analyzing the control of the silicon controlled dimmer at different trigger delay angles alpha (post-cut), whether the output current is kept constant or not is checked, and whether the LED dimming can be realized or not is judged, and the output current at the different trigger delay angles alpha is collated as follows:

from the above table:

the circuit works normally, when the silicon controlled rectifier back-cut dimmer controls different trigger delay angles alpha (back-cut), the input current does not reach 380mA, the output current increases along with the increase of the trigger delay angle alpha, and the LED lamp is brighter;

when the input current reaches 380mA, the input voltage is increased, the output voltage does not exceed 55V, and the circuit can limit the amplitude of the output voltage.

In summary, the silicon controlled dimmer can realize dimming, and the output current can be kept stable within the input voltage range of AC 180V-265V, so as to realize the preset target.
