Abstract
A vehicle lamp includes a light source configured to draw a road surface, a projection lens configured to transmit light emitted from the light source, and a movable shade disposed in the vicinity of a rear focal point of the projection lens. The movable shade includes at least one plate-shaped shade which has a light-shielding surface along a direction orthogonal to an optical axis of the projection lens. The at least one plate-shaped shade is formed with at least one light-transmitting part having an enclosed shape.
Claims18
A vehicle lamp comprising:
- a light source configured to draw a road surface;
- a projection lens configured to transmit light emitted from the light source;
- and
- a movable shade disposed in the vicinity of a rear focal point of the projection lens,
- wherein the movable shade is rotatable and comprises at least one plate-shaped shade which has a light-shielding surface along a direction orthogonal to an optical axis of the projection lens, and
- wherein the at least one plate-shaped shade is formed with at least one light-transmitting part having an enclosed rectangular shape that draws a rectangular light distribution pattern on the road surface.
A vehicle lamp comprising:
- a light source configured to draw a road surface;
- a projection lens configured to transmit light emitted from the light source;
- and
- a movable shade disposed in the vicinity of a rear focal point of the projection lens,
- wherein the movable shade comprises at least one cylinder or partial cylinder-shaped shade which has a curved light-shielding surface that curves around a center axis that is orthogonal to an optical axis of the projection lens, and
- wherein the at least one cylinder or partial cylinder-shaped shade is formed with at least one light-transmitting part having an enclosed rectangular shape that draws a rectangular light distribution pattern on the road;
- wherein the at least one plate-shaped shade further comprises an arrow-shaped opening portion that draws an arrow-shaped light distribution pattern on the road surface.
