Abstract
The reflective surface of a reflector 16 is divided through steps into a plurality of vertically elongated reflective surface elements. In each of those reflective surface elements, the light incidence section to which the output light of a light source bulb is applied is made up a convex cylindrical curved surface and a concave cylindrical curved surface which are arranged substantially in parallel with the step adjacent to the light incidence section. Accordingly, when the lamp is turned on, and the reflector is observed from the front, the light incidence sections function as follows; that is, the apex portions of the cylindrical curves surfaces look glittered as bright sections. Therefore, the reflective surface looks more sparkling.
Claims20
A vehicle lamp comprising:
- a light source bulb;
- and
- a reflector including a reflective surface for reflecting light from said light source bulb, at least a part of said reflective surface is divided into a plurality of reflective surface elements by steps disposed therebetween, each of said reflective surface elements comprising a light incidence section to which light emitted from said light source bulb is applied, and said light incidence section being constituted by at least two curved surfaces.
