Patent ID: 7195381

Claim:
A unitary light module for illuminating an interior portion of a vehicle, the vehicle having a battery/ignition voltage, said unitary light module consisting of: a housing having an inner surface forming a reflector and an outer surface having a plurality of heat dissipating fins; a single high-intensity power light emitting diode located inside said housing, said reflector at least one of directing and shaping light from said single high-intensity power light emitting diode toward a light output area of said housing; a lens covering said light output area of said housing, said lens at least one of directing and shaping light from said single high-intensity power light emitting diode toward an incident area of the vehicle; and a voltage conversion element adjacent said housing opposite said lens, said voltage conversion element including a DC step-down converter, said DC step-down converter adapted for reducing the battery/ignition voltage of the vehicle to less than 5 volts and increasing the current to at least 100 milliamps, and powering said single high-intensity power light emitting diode to deliver a luminous efficiency of at least 1 lumen/watt.
