Title:
DIMMING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/006540
Kind Code:
A1
Abstract:
Provided is a dimming device that is compatible with more types of illumination loads. The dimming device is provided with a pair of input terminals, a bi-directional switch, an input unit, a power supply unit (5), a control unit, and a current-limiting unit (53). The power supply unit (5) is electrically connected between the pair of input terminals, and generates a control power supply from power supplied from an AC power source. The control unit operates by receiving the supply of control power supply from the power supply unit (5), and controls the bidirectional switch in accordance with a dimming level. When current at or above a specified value flows from the AC power supply to the power supply unit (5), the current-limiting unit (53) stops the generation of the control power supply by the power supply unit (5).
