Abstract

An adapter for permitting a medical diagnostic instrument having an illumination source including at least one LED (light emitting diode) to be used with a power supply normally configured for use with a diagnostic instrument having at least one incandescent lamp as an illumination source. The adapter includes circuitry for compensating LED specific characteristics for permitting the power supply to be used with the LED.
