Headlamp system including HID and IR illuminators
A headlamp system providing both visible and IR illumination, provided in the same housing and using the same wiring harness as a headlamp system currently in use by the US Military, but instead of utilizing incandescent bulb technology as does the headlamp system currently in use, the headlamp system provided herewith utilizes HID lighting for visible light illumination, LEDs for blackout driving and marker lights, and an array of IR LEDs for IR illumination.
1 . A headlamp system ( 12 ), comprising:
a housing back component ( 12 a ) and a front component ( 12 b ), the front component affixed to the back component, the front component having slots into which a low beam HID light ( 18 a ) is inserted, a high beam HID light ( 18 b ) is inserted, and an infrared illuminator ( 19 ) is inserted;
ballasts ( 18 d 18 e ) affixed to the interior of the back component ( 12 a ) and electrically connected to the HID lights ( 18 a 18 b );
a printed circuit board ( 18 c ) electrically connecting the lighting components; and
a base ( 20 ) affixed to the housing back component, having a nut and a plurality of electrical connections allowing the headlamp system ( 12 ) to be physically connected to a vehicle and electrically connected to the vehicle's control panel ( 61 ) and power supply ( 62 ).
2 . The headlamp system ( 12 ) of claim 1 , wherein the infrared illuminator ( 19 ) comprises a housing ( 19 e ) enclosed by a cover ( 19 c ), the housing containing an array of infrared light emitting diodes, at least one infrared light emitting diode providing low beam operation and at least one infrared light emitting diode providing high beam operation.
3 . The headlamp system ( 12 ) of claim 2 , wherein the array of infrared light emitting diodes used are combined light-emitting diode-lens units ( 19 a 19 b ).
4 . The headlamp system ( 12 ) of claim 2 , wherein the infrared illuminator housing ( 19 e ) is made of aluminum.
5 . The headlamp system ( 12 ) of claim 1 , further comprising a blackout driving light ( 14 ) with a hood ( 14 a ) located above the low and high beam HID lights and a blackout marker light ( 15 ) located below the infrared illuminator ( 19 ).
6 . The headlamp system ( 12 ) of claim 1 , wherein the blackout driving light ( 14 ) and the blackout marker light ( 15 ) use light emitting diodes as light sources.
7 . The headlamp system ( 12 ) of claim 1 , wherein the headlamp housing has the same form and fit, mounting location, hardware, and is interchangeable with the headlamp system of the prior art ( 11 ).
