ABSTRACT:
A high intensity discharge lamp, suitable for use as a headlight for land, rail, water, aircraft, and motor vehicles in particular. The lamp includes glass containing Neodymium Oxide, a rare earth compound. The Neodymium Oxide filters out the yellow light portion of the spectrum, thereby producing a color corrected light. Incorporation of yellow light in the light spectrum desaturates colors and reduces contrast. Improvement in contrast and a reduction in glare permits, for example, a motor vehicle driver to better discriminate the contrast of objects when there is no daylight and the only illumination is artificial. For drivers, in particular, elimination of the yellow light lessens eye strain currently resulting from light emitted by the conventional headlights of oncoming vehicles during hours of darkness.
