摘要: An optical device for displaying a condensing mark includes a light source, and an optical element for condensing light emitted from the light source onto an irradiated surface. The deflection surface of the optical element is divided into a plurality of regions. The light emitted through the respective regions on the deflection surface of the optical element forms partial irradiation images corresponding to the respective regions on the deflection surface of the irradiated surface. The respective partial irradiation images are combined into at least one condensing mark on the irradiated surface.

摘要: Each of a road sign projector and a vehicle lamp operates in an assumed usage temperature of a car, and has reduced power consumption and reduced device cost. A road sign projector displays images onto a plurality of regions of a road surface. The road sign projector includes: shades each configured to shape image projection light into a predetermined shape corresponding to the image for each of the regions; and projection lenses corresponding to the regions. The projection lenses are different from one another in at least a focal length and axial inclination.
