Triac Dimmer Schaltung. The speed of the motor can be controlled by changing the setting of p1. Understand triac dimmer issues to ensure compatibility the lighting industry must overcome differences in lamp load lack of standards and legacy wiring problems to optimally pair a phase cut dimmer with an led lamp write marc gallo and michael neary.
Here we are using a bt136 triac for ac lamp dimming purpose. Pin number 1 is the anode and pin number 2 is the cathode as per the datasheet a 330 resistor is connected in series with the anode of the ir led. The ac bulb dimming circuit is based on the moc3021opto isolator triac driver and bta16 triac.

Creating the ideal configuration of led lamps with the triac dimmer has in the past been a challenge but the introduction of new triac dimming led drivers has made this much simpler. In scrs it conducts in only one direction but in the case of triac the power can be controlled at both directions.
