IR Light Dimmer Circuit Diagram for Household

The following page contains detail information regarding design and works of IR Light Dimmer Circuit Diagram for Household. The IR Light Dimmer is a device for adjusting lights in your home with any type of remote controller (tv, dvd, video). This device is based on PIC12F629 which is a small microchip microcontroller and therefore overall device is small and uses a few components.

Basic TRIAC Light Dimmer Circuit Diagram

The following schematic shows the Basic TRIAC Light Dimmer Circuit Diagram. The circuit is designed such that only a portion of the 60Hz sine wave from the VARIAC passes through the light bulb. TRIACs are electronic/ semiconductor devices equivalent to two silicon-controlled rectifiers (SCRs/thyristors) joined in inverse parallel, that is, once they are triggered, they continue conducting current until the current drops below the hold current, typically around the zero point (null) in the mains waveform.
