CA 2032338

An optical valve for use in a lamp of a motor vehicle comprises a main filament, and a sub-main filament. A multi-layer film is coated over a glass tube at the portion corresponding to the sub-main filament to produce yellow light. When driving at night and passing by a motor vehicle coming from the opposite direction, the sub-main filament is heated and produces the yellow light of which glare will not daze driver's eyes, thus preventing dangerous situations to the drivers.

Valve optique à utiliser dans un phare de voiture comprenant un filament principal et un filament secondaire. Une pellicule multicouche est appliquée sur un tube en verre à la partie correspondant au filament secondaire pour produire un feu jaune. Lorsqu'un chauffeur conduit à la noirceur et passe une voiture roulant dans le sens opposé, il ne sera pas ébloui puisque le filament secondaire se réchauffe et produit un feu jaune, évitant ainsi des conditions dangereuses.
