Abstract:
A fog lamp for a vehicle is disclosed. Light leaving an LED is collected by a refractive/TIR lens. The central portion of the refractive/TIR lens is purely refractive, while the peripheral portion of the lens includes a total internal reflection off an exterior surface of the lens. The refractive/TIR lens converges the light to a focus at or near a laterally-elongated aperture in a light baffle. Light exiting the aperture diverges and passes through an anamorphic lens, which reduces the angular extent of the beam in the vertical direction and increases the angular extent in the lateral direction. The full fog lamp may include multiple pairs of LEDs and respective refractive/TIR lenses, all arranged coplanar, parallel and laterally adjacent to each other. The LED/lens pairs may all direct light through a single light baffle and through a single anamorphic lens.
