HEADLIGHT DEVICE AND LEANING VEHICLE INCLUDING HEADLIGHT DEVICE
A headlight device including a headlight configured to emit light frontward of a leaning vehicle to form a lower light beam, an upper central light beam, an upper left light beam and an upper right light beam, and a control device that controls light emission from the headlight without any user operation. The control device forms both the upper left and the upper right light beams while the leaning vehicle is traveling straight, and reduces a brightness of the upper left and upper right light beams, responsive to a vehicle being illuminated by the upper left and upper right light beams respectively, and forms the upper left and upper right light beams respectively while the leaning vehicle is turning left and right, and maintains the brightness of the formed upper left or upper right light beam regardless of whether any vehicle is illuminated by the upper left or upper right light beam.
Vehicle external illumination device
A directional illumination device for a vehicle external light comprises an array of light sources and an imaging waveguide comprising an input surface and a reflective end. Opposed guide surfaces are arranged to guide input light from the input surface to the reflective end and back along the waveguide after reflection at the reflective end, the waveguide being arranged to extract input light as it is guided back along the waveguide after reflection and to cause the extracted light to exit through the first guide surface. The reflective end has positive optical power in the direction laterally across the waveguide and the waveguide is arranged to direct the extracted light in respective output illumination directions distributed in a lateral direction in dependence on the input positions of the light sources in the direction laterally across the waveguide. A thin, high brightness and high efficiency controllable directional vehicle headlight is provided.
Illumination module with multi light sources and headlight having the same
The present invention is an illumination module including at least one light path adjustment unit, at least one first light source, and at least one second light source.

Headlamp device
A headlamp device includes a headlamp, an object detector, and a controller. The headlamp is mounted on a vehicle and includes a light emitting unit composed of multiple light emitting cells. The object detector detects an object around the vehicle and generates an object detection signal including object coordinates corresponding to a location of the detected object. The controller controls light of the headlamp based on information on the object coordinates. The controller may control the light emitting unit such that at least some light emitting cells are turned off according to an object detection signal. Each of multiple light emitting units includes a circuit board, the multiple light emitting cells separated from each other on the circuit board, a molding member formed between the light emitting structures, and a protective member formed on the molding member to surround sides of the multiple wavelength conversion members while filling a gap between the multiple wavelength conversion members.

LED headlamp system with brightness control
A headlamp illumination source that switches from a first configuration conforming to on-road illumination standards to a second configuration that does not conform to on-road illumination standards. The switching is preferably controlled by a wireless signal but in some embodiments the switching can be controlled by a hard-wired signal or by a switch proximate the illumination source itself.

Method for correcting a light pattern, automotive lighting device and automotive lighting assembly
A method for correcting a first light pattern provided by a lighting device with a matrix of light sources. The method includes steps of providing some resolution data of the light sources, simulating a test map of the light pattern using the resolution data, and simulating distortion maps of the test map. Each distortion map is associated to a distortion factor. Also included is obtaining a real distorted light pattern, comparing the real distorted light pattern with the distortion maps, finding a distortion map which is the most similar to the real distorted map and applying a correction factor to correct the real distorted light pattern, thus obtaining a corrected light pattern. The correction factor is related to the distortion factor of the distortion map which is the most similar to the real distorted map.
