Patent ID: 11533795

Abstract:
A TRIAC single-fire-wire power-taking infrared smart dimmer includes a single-fire-wire input device, a bridge rectifier, a LDO power circuit, a zero-crossing detector, a phase cut dimmer, an overpower protector, an input device, a single-fire-wire output device, an infrared receiver circuit, a brightness indicator circuit, a minimum brightness setting device, a leading edge phase cut/trailing edge phase cut selecting device, and a single chip microcomputer minimum system. The infrared receiver circuit receives external data or data inputted by the input device to perform a smart control which can automatically distinguish and adapt an alternating current of 50 HZ or 60 HZ, select a leading edge phase cut dimmer or a trailing edge phase cut dimmer by an external module, and set a minimum brightness value. An indicator light is provided to display the current brightness percentage.
