| titleOfInvention | Dimming control circuit |
| abstract | The utility model discloses a dimming control circuit, including N parallelly connected dimming subcircuits, wherein dimming subcircuit includes the switch circuit of concatenating between direct current drive power supply positive negative pole and concatenates the output circuit between the load circuit positive negative pole, the switch circuit includes switching element, and the sampling point of output sampling signal, and the output circuit includes the sense terminal, judges whether output circuit has the electric current to pass through; the control circuit turns off the switching element according to the comparison result of the sampling signal and a preset turn-off threshold value, and turns on the switching element according to the detection signal. The dimming control circuit and the dimming control method provided by the embodiment of the application realize the aims of large-power load range, high efficiency, high-precision dimming, high-depth dimming, no stroboflash in the full dimming range, smooth dimming process and good driving internal heat distribution by alternately conducting the multi-path parallel circuit and combining the MCU or digital circuit controller control technology. |
