Dimmer Circuito. The central element in this switching circuit is a triode alternating current switch or triac. Since the general dimmer uses triac to control a load like a relay contact.
The central element in this switching circuit is a triode alternating current switch or triac. The dimmer circuit is wired in series with the lamp you can say the dimmer circuits is installed in series with the lamp. Dimmer circuits typically use coils that limit limit the rate of rise of current to that value which would result in acceptable emi.
All led lamps use dc operated circuits and therefore incorporate an internal bridge rectifier to convert the input ac to dc.
A triac is a small semiconductor device similar to a diode or transistor. Instead of merely turning lights on or off get a wide range of light by installing a dimmer switch. The dimmer circuit is wired in series with the lamp you can say the dimmer circuits is installed in series with the lamp. Most dimmers are designed to fit a standard wall box opening which makes it easy to replace the switch for any incandescent or halogen light with a dimmer.
