Abstract

The invention is applicable to the technical field of dimming, and provides a dimming circuit needing no distinguishing of input and output and a lighting system. The dimming circuit comprises a filtering module, a rectifying module, a signal control module and an MOS driving module. The rectifying module supplies power to the signal control module and the MOS driving module. When a first end of the filtering module is connected with a live wire and a third end of the filtering module is connected with a lamp, the signal control module sends a first dimming signal to the MOS driving module according to user input, and the MOS driving module outputs a dimming voltage to the third end of the filtering module according to the first dimming signal. When the first end of the filtering module isconnected with the lamp and the third end of the filtering module is connected with the live wire, the signal control module sends a second dimming signal to the MOS driving module, and the MOS driving module outputs a dimming voltage to the first end of the filtering module according to the second dimming signal. According to the invention, single-zero- / live-wire compatibility is realized, the live wire and the load wire do not need to be distinguished, the dimming circuit can work under random wiring, the operation is convenient, and the problem that normal work cannot be realized due to wrong wiring is avoided.

Description

technical field [0001] The invention belongs to the technical field of dimming, and in particular relates to a dimming circuit and a lighting system without distinguishing between input and output. Background technique [0002] Smart dimmer switches play an important role in smart homes, especially in hotels. When using smart dimmer switches, there are strict wiring requirements, but traditional smart dimmer switches often have misconnection of live wires and load wires (wires connected to lamps), which do not meet safety requirements and cause certain dangers. Contents of the invention [0003] In view of this, the embodiment of the present invention provides a dimming circuit and a lighting system that do not need to distinguish between input and output, so as to solve the problem that the live wire and the load wire are often connected incorrectly in the traditional intelligent dimming switch, which does not meet the requirements of safety regulations, causing certain ...
