Abstract
A two terminal pulse width modulated incandescent lamp dimmer using low frequency pulse repetition rate provides increased illuminating efficiency by compensating both for light producing inefficiency of a tungsten filament at dimmed level settings, and for internal resistance of a direct current power source. A preferred embodiment of the dimmer is designed for 3.5 to 9.0 volt operation.
