Problems solved by technology

[0003] However, when technicians need to install a large number of LED lamps, it is difficult to ensure that all LED lamps are installed correctly
If there are N LED lights connected in parallel and one of the LED lights is connected to the wrong polarity of the dimmer, technicians need to check each LED light one by one, which will consume a lot of time

Abstract

The invention relates to a dimmer polarity correction circuit. The circuit may include a control circuit, an adjustment circuit, and a detection circuit. The adjustment circuit can be connected with the control circuit, a working voltage input end and a dimmer and can comprise a plurality of switches. The adjustment circuit can receive the dimming signal of the dimmer. The detection circuit can beconnected with the dimmer and the control circuit, can detect the dimming signal to generate a reference voltage, and can transmit the reference voltage to the control circuit. The control circuit can keep the on-off states of the switches of the adjustment circuit unchanged or adjust the on-off states of the switches of the adjustment circuit according to the reference voltage.

Description

technical field [0001] The invention relates to a dimmer polarity correction circuit. Background technique [0002] Due to the advancement of technology, the functions of LED lights are becoming more and more powerful, and the manufacturing cost is also getting lower and lower, so they are more widely used. Generally speaking, when installing LED lamps, technicians need to pay special attention to whether the connection polarity of the dimmer connected to the LED lamp is correct, so as to avoid the abnormal operation of the LED lamp. [0003] However, when technicians need to install a large number of LED lamps, it is difficult to ensure that all LED lamps are correctly installed. If there are N LED lamps connected in parallel and one of the LED lamps is connected to the wrong polarity of the dimmer, technicians need to check each LED lamp one by one, which will consume a lot of time. Contents of the invention [0004] The invention provides a dimmer polarity correction ...
