Abstract:
1. A light assembly comprising: an array of light emitting diodes for a warning light generating a beam pattern having a center axis, wherein the light emitting diodes are arranged along a line, and wherein adjacent light emitting diodes are each regularly spaced at a first distance relative to one another along the line; a plurality of contiguous reflective regions with each region having optical properties distinct from optical properties of adjacent regions, where the plurality of contiguous reflective regions form a composite reflective surface having a generally parabolic cross-sectional shape, the composite reflective surface positioned to reflect at least a portion of the light emitted by each of the light emitting diodes from each of the reflective regions such that a center axis of the reflected light reflects in a direction generally perpendicular to the center axis of each of the light emitting diodes; one of the plurality of contiguous reflective regions including a plurality of parabolic regions configured to direct a portion of the reflected light emitted from the array of light emitting diodes to the center axis, with one of the parabolic regions corresponding to each of the light emitting diodes, and further comprising a second region bordering each of the parabolic regions configured to direct light up and down; and a pair of flanking reflective surfaces positioned on opposed ends of the array of light emitting diodes, each of the flanking reflective surfaces being flat, the flanking reflective surfaces each including a leading edge positioned adjacent to an outermost point of the contiguous reflective regions, and a trailing edge following the contiguous reflective regions to the leading edge, and the line along which the array of light emitting diodes is arranged intersects and is normal to each of the flanking reflective surfaces, wherein each of the flanking reflecting surfaces is positioned at a second distance, the second distance being one half the first distance between adjacent light emitting diodes so that the flanking reflective surfaces simulate an extended length of the reflector.
