Vehicle lamp and vehicle having the same
A vehicle lamp comprises a first light source group for forward illumination comprising at least one light emitting element, a second light source group for road surface drawing comprising at least one light emitting element provided separately from the at least one light emitting element, a single projection lens through which lights emitted from the first and second light source groups are to pass, and a light shade arranged between the first and second light source groups and the projection lens so that the light from the first light source group and the light from the second light source group do not intersect with each other before entering the projection lens. The projection lens has a first region through which the light from the first light source group is to pass and a second region through which the light from the second light source group is to pass.
High efficiency digital light processing engine
Systems and methods are disclosed for a pixelated light source that includes a plurality of pixels; a plurality of digital micromirrors configured to receive input light from the pixelated light source and configured to modify the input light to generate output light; and one or more controllers configured to control both the pixelated light source and the plurality of digital micromirrors to condition the output light.

Vehicle lamp including rotary reflector
An optical unit includes a light source and a rotary reflector configured to reflect a light emitted from the light source and rotate around a rotation axis in one direction. The rotary reflector is provided with a reflective surface such that a desired light distribution pattern is formed by scanning a light of a light source reflected by the rotary reflector while the rotary reflector is rotated. The light source includes a first light-emitting portion configured to be turned on when forming a first light distribution pattern that mainly illuminates a range lower than a horizontal line, and a second light-emitting portion configured to be turned on when forming a second light distribution pattern that illuminates a range at least higher than the horizontal line.

Systems and methods for search and landing light
A search and landing light system for a vehicle includes a hemispherical housing adapted to couple to the vehicle and a plurality of light emitting elements coupled to the hemispherical housing and arranged about a surface of the hemispherical housing. Each of the plurality of light emitting elements is configured to output a light beam. The search and landing light system includes a controller, having a processor in communication with each of the plurality of light emitting elements and configured to output one or more control signals to selectively activate at least one of the plurality of light emitting elements to output the light beam at a selected position relative to the vehicle.
Lighting Technology in the Automotive Area
An optical system includes optical fibers, a decoupling surface, an intersecting surface and a connecting portion. The optical fibers are arranged in at least one row. Each of the optical fibers includes a coupling surface onto which light from a light source is received. Light is directed through the optical fibers along an optical main axis. Light emitted from the optical fibers is directed onto a decoupling surface. The connecting portion is planar and is disposed between the decoupling surface and the optical fibers. The intersecting surface bounds the decoupling surface and is parallel to the optical main axis. Each of the optical fibers has an intersecting face oriented parallel to the optical main axis and parallel to the intersecting surface. The intersecting surface and the intersecting faces of the optical fibers generate a sharp outer edge of a light pattern formed by light emitted from the optical system.
Motor vehicle headlight module for emitting a light beam
The present invention relates to a module for a motor vehicle for emitting at least one light beam with a cut-off profile along an optical axis. The module includes first and second optical collectors adapted to collect light emitted by respective first and second light sources, and redirects the light toward a focal region. At least one of the collectors extends in the direction of the focal region in order to reflect some of the light emitted by the other collector so as to define the cut-off profile.

Vehicle lamp and control method thereof
A vehicle lamp includes: a low beam unit including a first light emitting unit and irradiating light only to region below a cutoff line; a high beam unit including a second light emitting unit and irradiating light to regions around and above the cutoff line; and a lighting controller that controls lighting of the low beam unit and the high beam unit. The lighting controller controls to switch between a low mode in which the low beam unit is turned ON and the high beam unit is turned OFF and a high mode in which the low beam unit and the high beam unit are turned ON, and a first light quantity irradiated by the low beam unit in the high mode is larger than a second light quantity irradiated by the low beam unit in the low mode.
