The control principle of RGB decorative lights

1. Brightness control: The luminous brightness of the strip can be controlled by controlling the current in the strip to control the luminous power of the strip. The output PWM of the DLT8F61SA IO port controls the MOS drive, and different duty cycles correspond to control the brightness of different LEDs.

2. Color control: DLT8F61SA three IO ports drive the R, G, B wicks of MOS control LEDs respectively; Monochrome luminescence is to drive only R or G or B to achieve monochrome red, monochrome green and monochrome blue luminescence. DLT8F61SA drive R, G, and B at the same time, the LED emits white light. Arbitrarily drive the two channels in R, G, and B, and PWM can achieve more colors by giving different duty cycles. If the timing of the driver R, G, and B is different, it can realize a variety of different forms of color transformation effects such as LED flicker and gradient.


1. The solution supports infrared remote control, 100% effective after infrared buttons, and there is no code drop;

2. DLT8F61SA supports 16 kinds of monochrome output. The monochrome colors are red, orange, yellow, dark yellow, light yellow, green, light green, cyan, light blue, light blue, blue, dark blue, brown, purple, pink, white;

3. DLT8F61SA support brightness speed adjustment: brightness 8 levels (100%), speed 4 gears;

4. DLT8F61SA support seven-color jump function, color cycle: red-green-blue-yellow-purple-cyan-white;

5. DLT8F61SA support respiratory function: white from off to bright, from bright to off;

6. DLT8F61SA support 3-color gradient function: red-green-blue-red;

7. DLT8F61SA support three-color jumping: red-green-blue,

8. The chip has a power-off memory function, and the power-on LED light state is the switch state before the last power-off;
