VEHICLE LAMP
A vehicle lamp (1) includes a light source (30) that emits pieces of laser light (LR, LG, LB) having different wavelengths in a time division manner, and a plurality of diffraction gratings (43R, 43G, 43B) corresponding to the pieces of laser light (LR, LG, LB) of the wavelengths, respectively. The laser light (LR, LG, LB) of the wavelengths emitted from the light source (30) are incident on the diffraction gratings (43R, 43G, 43B) corresponding to the laser light (LR, LG, LB), and regions irradiated with light (DLR, DLG, DLB) emitted from the diffraction grating (43R, 43G, 43B) overlap with each other.
Lighting device
A substrate supports a light source and a control circuit. The control circuit is configured to be able to control lighting and lights-out of the light source. The substrate is supported to a conductive housing. The housing is configured to couple with a transparent cover through which light emitted from the light source is to pass. The housing has a through-hole. A connector unit has a connection part and a terminal holding part. The connection part is arranged outside the housing. At least a part of the insulating terminal holding part is arranged in the through hole. The terminal holding part holds a conductive terminal. The conductive terminal is coupled to the substrate and electrically connected to the control circuit.
Variable headlamp apparatus for vehicle
A variable headlamp apparatus for a vehicle is capable of realizing various lighting functions by switching positions of the plurality of optical units only with a single drive unit. The variable headlamp apparatus includes: an optical unit having an emitter to emit light; a guide unit installed with the optical unit to guide a position of the optical unit to a fixed path; a link unit connected to the optical unit and including multiple links rotatably connected to each other to change the position of the optical unit; and a drive unit to rotate the links. In particular, the optical unit moves along the fixed path of the guide unit while switching a light irradiation direction of the emitter.
ONE-PIECE LENS WITH DRIVEN WHEEL SECTOR
The present invention relates to a vehicle lighting device including a lens intended to deflect the light rays emitted by a light source and including a wheel sector with a driven surface. The wheel sector is made in one piece with the lens as a whole. Also included is a driving means with a driving surface such that the driving surface is in contact with the driven surface, and movement of the driving surface drives movement of the lens.
Lighting device that produces a main beam and a narrow beam that is orientable depending on the position of an obstacle detected in front of a vehicle
A vehicle equipped with analysing means that analyse a zone (ZA) located in front of the vehicle is equipped with a lighting device (DE). This device (DE) comprises: a first source (S1) that generates first photons and a reflector (RP) that reflects the first photons toward the zone (ZA) so that they form a first light beam (F1) that performs a photometric lighting function, a second source (S2) that is installed in front of a central portion (PC) of the reflector (RP) and that generates second photons, a lens (LF) that is inserted between the second source (S2) and the zone (ZA), that is positionable in various positions, and that forms, with the second photons, a second light beam (F2) that is narrow and that points toward a sub-zone of the zone (ZA) that depends on a set lens position, andcontrolling means (MC) that set the position of the lens in case of detection of an obstacle in a sub-zone of known position.
