Kind Code:
A1
Abstract:
A mechanical turnplate type rotatably dimming device has a bottom part (1) and a front part (7) of a lamp holder, which form a cavity for holding a dimming part. The dimming part comprises a PCB (5) with potentials, an electric brush (4), a transmission unit (3), and a turnplate (25) driving the transmission unit (3) to rotate. The potential region of the PCB (5) is equally divided into multiple equal parts, and each part is correspondingly connected to a sampling output end. An end of an electric brush (4) is fixed on the transmission unit (3) and another end is elastically contacted with the potential region of the PCB (5). The transmission unit (5) is buckled with the turnplate (25).
