Abstract:
1. A light assembly having an intended direction of light emission, said light assembly comprising: a generally concave reflector defining a compound reflecting surface which flares to a front opening in the direction of light emission, said compound reflecting surface comprising: a primary reflecting surface defined by a portion of a first parabola having a first focus and a first axis; and a secondary reflecting surface defined by a portion of a second parabola having a second focus and a second axis, said secondary reflecting surface interrupting said primary reflecting surface within an angle originating at said first focus and bisected by said axis, said angle being in the range of 30° to 90°, wherein said second focus is coincident with said first focus and said second axis is angularly offset relative to said first axis by an angle of deflection a in the range of 30° to 70°, and said secondary reflecting surface comprises that portion of said second parabola extending between said first axis and said first parabola; a light source support having a length and a width, said length and width measured perpendicular to said direction of light emission; an LED light source comprising at least one LED mounted to said light source support, said at least one LED having a point of light emission and an optical axis originating at said point of light emission; said light source support mounted within said reflector with the at least one LED point of light emission coincident with said first focus and said optical axis aligned with said first axis, said LED light source arranged to emit light in a direction opposite to the intended direction of light emission.
