Abstract
A multiple illumination element lamp apparatus is disclosed of a carriage that includes a proximal reflector having abase and a surrounding sidewall extending from the base to define a proximal reflector interior separated from an exterior environment. The multiple illumination element lamp also includes a first and a second illumination element both disposed within the proximal reflector interior, wherein the first illumination element produces a substantially high brightness light level an the second illumination element produces a substantially low brightness light level. Further, in the multiple illumination lamp the fist and second illumination elements are sized and configured to produce substantially a same light beam shape and projection with the high and low brightness levels.
Claims14
A multiple illumination element lamp apparatus for a carriage, comprising:
- (a) a proximal reflector having a base and a surrounding sidewall extending from said base to define a proximal reflector interior separated from an exterior environment;
- and
- (b) a first and a illumination element both disposed within said proximal reflector interior, wherein said first illumination element produces a substantially high brightness light level and said illumination element produces a substantially low brightness light level, said fist and second illumination elements are sized and configured to produce substantially a same light beam shape and projection with said high and low brightness levels.
A multiple illumination element lamp apparatus for a locomotive headlight, comprising:
- (a) a proximal reflector having a base and a surrounding sidewall extending from said base to define a proximal reflector interior as separated from an exterior environment;
- and
- (b) a first and a second tungsten carbide filament both disposed within said proximal reflector interior, wherein said first tungsten carbide filament produces a substantially high brightness light level and said second tungsten carbide filament produces a substantially low brightness light level, said fist and second tungsten carbide filaments are sized and configured to produce substantially a same light beam shape and projection with said high and low brightness levels.
A multiple illumination element lamp apparatus according to claim 14 wherein said first and second tungsten carbide filaments are sized and configured to operate at substantially the same voltage.
