A condenser lens includes an exit surface divided into a plurality of light controlling surfaces. The exit surface includes a first exit region and a second exit region. The first exit region includes a plurality of first light controlling surfaces arrayed in a predetermined direction. The second exit region is located side by side with the first exit region and includes a plurality of second light controlling surfaces arrayed in the predetermined direction. A border between adjacent first light controlling surfaces and a border between adjacent second light controlling surfaces are out of alignment in the predetermined direction.

Lens and lamp

Provided is an optical unit capable of preventing unintended light distribution and having a small assembly error while using a plurality of light sources and a plurality of lenses. An optical unit () includes: a plurality of light sources (); a plurality of first lenses () integrally formed, respectively arranged to correspond to each of the light sources (), condensing light from the corresponding light sources (), and forming corresponding light source images on a predetermined virtual plane; a second lens () projecting projected images of the light source images forward; and a light-shielding member () extending between two adjacent first lenses () in the first lenses (), and shielding light passing through one first lens () so as not to enter the other first lens (), in which the light-shielding member () and the first lenses () are integrally formed by two-color molding.

Optical unit

A vehicle lamp includes: a light source; and a scanner configured to scan light emitted from the light source, and configured to irradiate the scanned light toward outside a vehicle. The light source includes a plurality of visible light sources configured to emit visible light, and at least one infrared light source configured to emit infrared light, and the infrared light source is arranged between the visible light sources.

Vehicle lamp

The present invention relates to a vehicle headlight that ensures maintaining usage efficiency of a light of the vehicle headlight while improving visibility of an irradiation target on a road by a headlight light from a host vehicle.
