<p>PURPOSE:To obviate a cap glass and realize small size and light weight by absorbing light transmitted through a glass lens body and moderating emitted light into discoloration at all times, by Cu ions or, etc., entering the main surface of a glass lens by ion exchange. CONSTITUTION:Lighting equipment for a vehicle such as a car consists of a light source lamp 1, a lighting equipment mainframe 2 to mount it on, a reflecting mirror 4 to intensively project light emitted from the lamp 1 to the front, and a front glass lens 5 to seal the opening of the mainframe 2. In this way, the glass lens 5 is so constructed that yellow spectrum light is transmitted to moderate light emitted from the lamp 1 or by an ion exchange layer to develop such a phenomenon. That is, at least one main surface of the lens mainframe is formed with the ion exchange layer to show a yellow color. For its purpose, pasted silver salt or copper salt is applied to the surface of the lens mainframe including alkali ions such as Ns ions with solvent, dried at 150-200 deg.C, and then baked thereto at 500-600 deg.C.</p> |
