Abstract: A single-fire-wire TRIAC wireless smart dimmer includes a single-fire-wire input device, a single-fire-wire output device, an AC/DC circuit, a bridge rectifier, a frequency/zero point detection circuit, a chopped-wave dimming circuit, an overload protection circuit, a single chip microcomputer minimum system, an input device, a brightness display circuit, a minimum chopped-wave value setting circuit, a chopped-wave phase selection circuit, and a RF transceiver circuit. A single-fire-wire power taking method is used to maintain the normal operation of the dimmer and overcome the issue of insufficient current for the wireless transmission/receiving operations. The dimmer is capable of automatically distinguishing and adapting an alternating current of 50 HZ or 60 HZ, selecting the phase of a leading edge or trailing edge chop wave, providing better control of compatible power supplies, setting minimum chop wave value, providing overload protection, and displaying brightness percentage.

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.
