1. A dimming processing system for LED lamps, comprising:
a signal input area, a plurality of electronic color trigger switches located in the signal input area, a hue, saturation, value (HSV) color selection area composed of the plurality of electronic color trigger switches, and a non-color selection area located in the signal input area,
a value module, and
a dimming processing module,
each of the electronic color trigger switches corresponding to an HSV value, and only one electronic color trigger switch is triggered at a time,
the HSV color selection area is a circular area, a position of each electronic color trigger switch in the circular area is represented by a polar coordinate system, the non-color selection area comprises a plurality of electronic selection switches, and
the value module is configured to turn on one of the selected electronic color trigger switches in the HSV color selection area having the largest distance from a pole of the polar coordinate system when at least one of the electronic color trigger switches and at least one of the electronic selection switches are sequentially selected, or when the at least one electronic selection switch and the at least one electronic color trigger switch are simultaneously selected, and the HSV value corresponding to the electronic color trigger switch is extracted, the dimming processing module adjusts the HSV value of light emitted by the LED lamp according to the HSV value corresponding to the turned-on electronic color trigger switch;
the value module further comprises a comparison unit, the comparison unit is configured to compare a distance between each selected electronic color trigger switch and the pole of polar coordinates with a pole diameter length value of the polar coordinates when at least one of the electronic color trigger switches and at least one of the electronic selection switches are sequentially selected, or the at least one electronic selection switch and the at least one electronic color trigger switch are simultaneously selected.
