Problems solved by technology

[0005] However, the existing remote control dimmer is equipped with a wireless communication module for wireless communication with the remote control. The wireless communication module needs to be powered continuously to ensure that it is in working condition. A rechargeable battery and a charging control circuit are additionally set up. When the light is on, the mains alternating current supplies power to the wireless communication module, and when the light is off, the rechargeable battery is used to supply power to the wireless communication module. As a result, the remote control Higher cost of dimmers

Abstract

The invention discloses a remotely-controllable dimmer circuit. The remotely-controllable dimmer circuit comprises a zero-voltage detection circuit, a rectifying circuit, a energy storage and voltagestabilization circuit, an electronic switch circuit, a wireless communication module and a signal processing control circuit. The characteristic that a dimmable LED lamp widely used at present is different from a non-dimmable LED lamp is utilized, so that the dimmer circuit not only can be applied to the dimmable LED lamp, but also can be suitable for a dimmable incandescent lamp; a voltage valueof an alternating current of commercial power is determined through cooperation of a zero-voltage detection circuit and a signal processing control circuit; in a time interval that the instant voltagevalue of the alternating current of the commercial power is relatively small, the energy storage and voltage stabilization circuit acquires working electric energy required by the dimmer circuit; andin an interval that the instant voltage of the commercial power is relatively high, the signal processing control circuit adjusts an effective voltage input to the dimmable lamp by setting a controlperiod of the commercial power so as to adjust the brightness of the dimmable lamp. The remotely-controllable dimmer circuit has the advantage that a remote control function of a dimmer is realized with relatively low circuit cost.

Description

technical field [0001] The invention relates to a dimmer circuit, in particular to a remote control dimmer circuit. Background technique [0002] In the period when incandescent lamps were commonly used, it was a very common application to use a dimmer to dim the incandescent lamps. Through the operation of the dimmer, the incandescent lamp can be turned on, off and the brightness adjusted, which can not only meet the needs of different users for different brightness, but also achieve the purpose of energy saving. [0003] The dimmer has an input terminal and an output terminal, and the incandescent lamp as a dimmable lamp has a live wire input terminal and a neutral wire input terminal. In practical applications, the input end of the dimmer is connected to the live wire of the mains, the output end of the dimmer is connected to the live wire input end of the incandescent lamp, and the neutral wire input end of the incandescent lamp is connected to the neutral wire of the m...
