ABSTRACT:
A lamp containing a fill of xenon, mercury and metal halide is disclosed which serves as a light source for lighting applications and is particularly suitable for automotive forward lighting applications. The xenon ingredient operates to provide for instant light necessary for automotive applications, whereas, the mercury and metal halide ingredients operate to provide for a long life, high efficiency lamp relative to either a xenon or tungsten lamp. The dimensions of the xenon-metal halide lamp of the present invention are approximately three-fifths (3/5) of those of a typical tungsten lamp utilized for automotive forward lighting applications. The reduced dimensions of the xenon-metal halide lamp allows for correspondingly reduced dimensions of a related reflector for such a xenon-metal halide lamp which accommodates the needs of aerodynamically styled automobiles.
