A fog lamp for use in an automobile includes a plurality of reflectors each sharing a common focus point, a light emitting diode array positioned at the common focus point, and a circular, non-optic window. The window fits through a standard-sized opening in an automobile fascia substantially two inches in diameter. The reflectors include a central reflector, a pair of lateral reflectors surrounding the central reflector and angled toward a center axis of the fog lamp, and a pair of converging reflectors surrounding the lateral reflectors and angled more sharply toward the center axis of the fog lamp. The central reflector and lateral reflectors produce beams of reflected light through the outer circumference of the window. The converging reflectors produce beams of reflected light converging at a secondary focus point within the fog lamp and transmitting through the window. |

1. A fog lamp for an automobile, comprising:
a circular transparent window, the window having a center, an outer circumference, and a lamp axis extending through the center, a plurality of reflectors positioned behind the window, each reflector being operable to produce reflected rays of light and having a focus located at a common focus point located between the reflectors and the window, and a light emitting diode (LED) array positioned at the common focus point, the LED array being operable to direct light toward the plurality of reflectors, wherein the plurality of reflectors includes:
a central reflector having a principal axis that extends parallel to the lamp axis, anda pair of lateral reflectors positioned on opposite sides of the central reflector, (i) each lateral reflector having a first edge connected to the central reflector and a concave surface extending from the first edge to a second edge, and (ii) each lateral reflector being operable to produce a first reflected ray having an origin located on the first edge, the first reflected ray extending across the lamp axis and through the outer circumference of the window, and a second reflected ray having an origin located on the second edge, the second reflected ray extending away from the lamp axis and through the outer circumference of the window. |
