Abstract
A warning beacon or a light where clusters of LED are mounted on a circuit board and emit light into a conical reflector so as to provide omni directional illumination has improved illumination intensity over its pattern of illumination by utilizing separate reflective sections each of which is preferably parabolic. Separate clusters of LEDs (light emitting devices) are arranged along circular paths (in rings) of diameter commensurate with the diameter of each section of the reflector aimed at approximately the middle thereof. The illumination is deflected radially outward from each section. The total number of LEDs which provide the illumination is increased over other arrangements thereby enhancing the brightness or intensity of illumination provided by the beacon.
