Abstract:
A lighting apparatus includes an input power terminal, a light source element coupled to the input power terminal, and a current bleeder module that is connected to the input power terminal and is configured to draw a current from the input power terminal responsive to a phase cut input power signal received at the input power terminal during a first portion of a period of the phase cut input power signal and is configured as an open circuit so as not to draw current from the input power terminal during a second portion of the period of the phase cut input power signal.
