| 简介 |
Motor vehicle windshields and safety glazing material, suitable for use as a motor vehicle windshields and safety glazing material for automobiles, trucks, buses, motorcycles, locomotives, sport utility vehicles, all terrain vehicles, and vans contain Neodymium Oxide, a rare earth compound. The Neodymium Oxide filters out the yellow portion of a spectrum, reducing glare. Incorporation of yellow light in the spectrum desaturates colors and reduces contrast. Improvement in contrast and 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. Neodymium Oxide can also be added to safety glazing materials for use in bullet resistant shields. A reduced glare window glass, suitable for use in glass window, also contains Neodymium Oxide, a rare earth compound. The Neodymium Oxide filters out the yellow light of the spectrum, thereby providing improved vision. Incorporation of yellow light in the light spectrum desaturates colors and reduces contrast. Improvement in contrast and a reduction in glare permits, for example, one to use this window glass in a building to reduce glare without the expense of blinds and curtains that are normally used to reduce glare. This glass can be used for multiple layers of glass in assembled glazing.© KIPO & WIPO 2009 |
