Abstract
A system and method that contemplates operating an LED at its characterized current (e.g. 400 mA) for any luminous intensity. A Pulse Width Modulation (PWM) is employed, wherein the pulse width of the pulse width modulated signal is used to control the luminous intensity of the LED. Optionally, the LED can be biased to reduce the intensity of the pulses used to operate the LED.
