Wide angle warning light

Claim 1

A wide angle light source comprising: means defining a reflector, said reflector defining means including: a first end section, said first end section having a concave reflective surface which at least in part defines a first portion of a paraboloid of revolution about a first axis, said concave reflective surface of said first end section extending inwardly from a forward edge which is at least in part arcuate; a second end section, said second end section having a concave reflective surface which at least in part defines a portion of a paraboloid of revolution about a second axis, said second axis being oriented generally parallelly to said first axis, said concave reflective surface of said second end section extending inwardly from a forward edge which is co-planar with the forward edge of said first end section; and a linear intermediate section having a concave reflective surface, said intermediate section being integral with and extending between said end sections, said intermediate section having a rear wall portion which interconnects a pair of parallel side wall portions, said rear wall portion at least in part having a profile which is a paraboloid having a focal point defining a straight line intersecting said first and second axes, said side wall portions of said intermediate section defining a pair of parallel linear forward edges which are generally co-planar with said forward edges of said first and second end sections; a leans means adapted to be secured to said reflector defining means, said lens means and reflector-defining means cooperating to form a chamber bounded in part by said reflective surfaces; and light emitter means disposed in said chamber, said light emitter means comprising a gaseous discharge tube having a pair of leg portions and an elongated linear intermediate portion which interconnects first ends of said leg portions, said leg portions extending outwardly from said light emitter means intermediate portion to said reflector-defining means whereby said light emitter is supported from said reflector-defining means by said legs, said linear intermediate portion of said light emitter means defining an axis which is oriented generally parallel to said reflector-defining means intermediate section forward edges, said light emitter means intermediate portion axis being positioned inwardly toward said reflector means intermediate section rear wall portion with respect to the plane in which said forward edges of said reflector defining means sections lie.
