ABSTRACT:
A lamp includes a voltage conversion circuit entirely within a lamp base. The voltage conversion circuit includes a pulse width modulator for modulating a lamp load voltage and provides a load voltage to a light emitting element. A feed-back circuit adjusts the pulse width modulator in response to the load voltage to cause an RMS load voltage to reach a predetermined level.
