Patent ID: 8299715

Claim:
A pulsed diode light source driver comprising: a diode driver section comprising a switchable linear current driver coupled in series with a plurality of diode nodes for connecting to a diode light source; a power supply having an output coupled to the diode driver section for providing an output voltage thereto, and an adjust node for controllably varying the output voltage as a function of deviation in an electrical property at the adjust node from a predetermined value; an output capacitor coupled to the output of the power supply; a temperature sensor physically disposed relative to the output capacitor for indicating temperature thereof with a temperature-varying signal; a conditioning circuit for perturbing the electrical property at the adjust node from the predetermined value as a function of the temperature-varying signal to thereby vary the output voltage of the power supply in accordance with a voltage-temperature profile for the output capacitor, the conditioning circuit being coupled to the temperature sensor for receiving the temperature-varying signal; and a voltage monitor for restoring the electrical property at the adjust node to the predetermined value as a function of change in the output voltage of the power supply to thereby vary the output voltage of the power supply in accordance with the voltage-temperature profile for the output capacitor, the voltage monitor being coupled to the output of the power supply; wherein the pulsed diode light source driver is operable for maintaining current pulses from the diode driver section constant over a temperature range, and the voltage-temperature profile for the output capacitor is operatively effective for maintaining current pulses from the diode driver section constant over a low end of the temperature range.
