Abstract
A headlamp for a vehicle (air, land or sea) providing a planar array of infrared (IR) light-emitting diodes (LEDs) and visible light LEDs, and arranged and mounted within a housing so as to provide for cooling of the LEDs without forced convection, by conducting heat from the LEDs to protruding cooling fins. A switch system is also provided, for enabling either the visible light or the infrared light, and for selecting a high-beam or low-beam pattern. The beam pattern is provided in some embodiments so as to meet US Federal Motor Vehicle standards.
