Patent ID: 7118245

Claim:
A trainman's lantern, comprising: a reflector comprising inner and outer reflective surfaces; a primary light source mounted internal to said reflector so that light from said primary light source is reflected by said inner reflective surface so as to project in a generally axial direction from said reflector, said inner reflective surface of said reflector having a generally concave curvature so that said light from said primary light source is reflected in a relatively concentrated beam; and at least one secondary light source mounted external to said reflector so that light from said secondary light source is reflected by said outer reflective surface so as to project in a generally lateral direction from said lantern, said outer reflective surface of said reflector having a generally convex curvature so that said light from said at least one secondary light source is reflected in a relatively dispersed pattern, said at least one secondary light source comprising: a plurality of LEDs having beams that are directed towards said outer reflective surface of said reflector so as to be reflected in said lateral direction therefrom, said plurality of said LEDs being mounted at spaced locations around said reflector so that said light therefrom is reflected in a substantially radial pattern; said reflector further comprising: a plurality of ports formed in said reflector that permit light from said primary source to pass therethrough in a lateral direction so as to augment said light from said at least one secondary source, said plurality of ports being formed in said reflector at spaced locations intermediate said LEDs.
