Abstract:
A warning device. In some embodiments, the warning device can include: a plurality of light sources forming an array; a plurality of reflectors, with at least one reflector being associated with each of the plurality of lights; and a plurality of lenses, with at least one lens being associated with each of the plurality of lights. In some examples, each of the plurality of reflectors and the plurality of lenses is tilted along a principal axis to collimate light and to direct the light from one of the plurality of lights to one of a plurality of far field light spots.
