Abstract:
A vehicle light capable of switching between a low-beam mode and a high-beam mode by moving a movable portion, comprising:a light source; a first reflecting surface having a longitudinal direction along an optical axis of the vehicle light, and having a first focus in the vicinity of the light source; a projection lens; a shutter selectively insertable in luminous flux located between the first reflecting surface and the projection lens; a second reflecting surface of an ellipse group reflecting surface having a first focus approximately on the light source and a second focus at a predetermined position; at least one third reflecting surface having a first focus in a predetermined position and at least one second focus in at least one predetermined position; and a fourth reflecting surface having a focus approximately on the second focus of the second reflecting surface; wherein when the third reflecting surface is located in an inserted position relative to luminous flux located between the second reflecting surface and the fourth reflecting surface, the first focus of the at least one third reflecting surface is substantially on the second focus of the second reflecting surface; and wherein the movable portion includes the shutter and the at least one third reflecting surface.
