Abstract

A TRIAC-dimmable LED lamp driver allowing wide dimming range is proposed. The concept is based on introducing reactive power flow to increase the input current higher than the holding current of the TRIAC, while the input active power is regulated. A LED prototype has been built and tested. Experimental results reveal that the true firing angle of the TRIAC can be adjusted down to 172°, and the lamp power can be dimmed from 7.2W to 0.3W linearly.
