ABSTRACT:
A lamp, suitable for use as a headlight for land, water and aircraft and motor vehicles in particular. The lamp includes glass containing Neodymium Oxide, a rare earth compound. The Neodymium Oxide filters out the naturally occurring yellow light produced by a hot incandescent filament, thereby producing a color-corrected light. Yellow light contributes to a lack of contrast. Improvement in contrast 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 excessive yellow light lessens eyestrain currently resulting from light emitted by the conventional headlights of oncoming vehicles during hours of darkness. Lamps of increased wattage than present can be used without increasing eyestrain from opposing motor vehicles, which in turn leads to better contrast, and thus improved night time visual acuity, resulting from the increased amount of light for a driver of a motor vehicle equipped with the herein disclosed color corrected headlight.
