Title: Vehicle headlight cover, vehicle with it, and its defogging method
Inventor: HAYAKAWA MAKOTO
IPC: E01F9/619
Filed: 1996-09-10
Abstract: PROBLEM TO BE SOLVED: To provide a headlight cover glass and its defogging method which can achieve a high degree of visibility by equipping the cover at least on its internal surface with a substantially transparent surface layer containing titanium oxide particles to work as photocatalyst. SOLUTION: A layer containing titanium oxide (crystalline) or the like to work as photocatalyst is formed on the surface of a base material. When applied to the internal surface of a cover for the headlight of a vehicle, this surface structure is turned hydrophilic to a high degree in response to photo-excitation of the photocatalyst caused by ultraviolet rays contained in the beams of light emitted by the headlight. Even when the moisture in the atmosphere is condensed to be attached to the surface of the base material, it will not grow to water drops, but a uniform water film is produced. This allows preventing the headlight cover from being foggy by the condensate and/or water drops. The surface layer may consist of particles of titanium oxide solely, or amixture of titanium oxide particles with ordinary inorganic oxides.
