VEHICLE HEADLIGHT AND VEHICLE HEADLIGHT SYSTEM
A control unit (CO) in a vehicle headlight (1) controls a light emitting unit (10) such that, when a signal indicating another vehicle (80, 90) is input, a region including a first region (211, 311) in a light distribution pattern (200, 300) becomes a light reduction region (210, 310) in which a total light flux amount of light from the light emitting unit (10) decreases as compared with that before the signal indicating the other vehicle (80, 90) is input, and controls the light emitting unit (10) such that, when a signal indicating a turn sign of the other vehicle (80, 90) is input, at least the first region (211, 311) in the light reduction region (210, 310) expands to a turning direction side indicated by the turn sign as compared with that before the signal indicating the turn sign of the other vehicle (80, 90) is input.
IMAGING SYSTEM WTIH ADAPTIVE HIGH BEAM CONTROL
An imaging system is provided herein. An image sensor is configured to acquire one or more images of a scene external and forward of a controlled vehicle and to generate image data corresponding to the acquired images. A controller is communicatively connected to the image sensor and is configured to receive and analyze the image data. The controller detects an object of interest in the image data and generates an ON signal or an OFF signal based on the detection of the object of interest in the image data, or lack thereof. A high beam control of the vehicle is turned ON based on the ON signal or turned OFF based on the OFF signal. The controller modifies a future response time at which the OFF signal is generated based on an external overriding of the ON signal or the OFF signal.
Vehicle headlight system
A vehicle headlight system can include a headlight controller and a lamp unit incorporating a high beam module, which can emit favorable marking lights while the headlight controller associates each of a shading driver and a swivel structure with a shading width setter and a swivel setter, respectively. When a forward vehicle does not exist in a forward direction, the headlight systems can provide favorable light distribution patterns by overlapping the light distribution pattern projected from the high beam module with each of light distribution patterns for a high and low beam. When the forward vehicle exists, the headlight system can prevent the lamp unit from emitting a glare type light to the forward vehicle. Thus, the disclosed subject matter can provide vehicle headlight systems, which can emit favorable light patterns toward a pedestrian as a marking light, and which can provide favorable light distribution patterns to drive at night.
VEHICLE LIGHTING DEVICE AND METHOD FOR OPERATING VEHICLE LIGHTING DEVICE
A lighting device for a vehicle has at least one headlamp having a plurality of lighting elements which are individually controllable. A method of controlling the lighting device includes detecting an activated state of the at least one headlamp;
detecting a body to be protected from glare; determining a glare suppression angular range based on an extent and position of the body; and determining at least one transition angular range between the glare suppression angular range and a fully illuminated angular range. The light intensity of the glare suppression angular range is set below a specified limit The light intensity of the transition angular range depends on a distance of a beam angle of the individual lighting elements from the glare suppression angular range, wherein the light intensity increases with increasing distance.
Illumination apparatus having a coherent light source and diffraction optical device that has a plurality of diffraction zones and widens the width of the illumination zone
An illumination apparatus that illuminates an illumination zone having a first direction and a second direction crossing the first direction is provided with a light source to emit a coherent light beam, and a diffraction optical device to diffract the coherent light beam incident from the light source. The diffraction optical device diffracts the incident coherent light beam so that a width of the illumination zone in the second direction gradually becomes wider along the first direction of the illumination zone from a nearer side to the diffraction optical device.
OPTOELECTRONIC DEVICE AND ADAPTIVE ILLUMINATION SYSTEM USING THE SAME
An automotive headlight is disclosed including: an optical unit including a plurality of optical elements, each optical element having a different central direction; a segmented light-emitting diode (LED) chip including a plurality of LEDs that are separated by trenches formed on the segmented LED chip and arranged in a plurality of sections, each section being aligned with a different respective optical element, and each section including at least one first LED and at least one second LED; and a controller configured to: apply a forward bias to each of the first LEDs, apply a reverse bias to each of the second LEDs, and change a brightness of the first LEDs in any section based on a signal generated by the second LED in that section.
LED HEADLAMP WITH REFRACTIVE INTERFACE CREATING CUT-OFF FOR VEHICLES
The present invention relates to a lighting module for an automobile headlamp that is able to emit a cut-off light beam along a predetermined optical axis. The lighting module includes a light source for generating a beam and an optical element for receiving the beam generated by the light source and configured to form from this beam the cut-off light beam. The optical element has a collimator configured to receive the beam generated by the light source and to collimate this beam into a collimated beam. An optical coupler is configured to couple the collimated beam into a coupled beam in a lightguide. A cut-off means is disposed within the lightguide on the path of the rays of the coupled beam and configured to intercept a portion of the rays in the lightguide and to form a cut-off beam. At least one output face of the lightguide is configured to project the cut-off beam outside of the optical element, and the optical element is formed as a single part.
VEHICLE LAMP
A vehicle lamp is provided, which is capable of changing the clearness of a contrast boundary line correspondingly to a traveling state or a traveling environment of a vehicle. The vehicle lamp is mounted in a vehicle and configured to form a prescribed light distribution pattern including a contrast boundary line, the vehicle lamp including: a sensor provided in the vehicle; and a clearness control unit configured to change clearness of the contrast boundary line correspondingly to a detection result of the sensor.
Optical unit, vehicle monitor, and obstruction detector
Disclosed is an optical unit wherein a rotating reflector rotates about a rotation axis in one direction, while reflecting light emitted from a light source. The rotating reflector is provided with a reflecting surface such that the light reflected by the rotating reflector, while rotating, forms a desired light distribution pattern, said light having been emitted from the light source. The light source is composed of light emitting elements. The rotation axis is provided within a plane that includes an optical axis and the light source. The rotating reflector is provided with, on the periphery of the rotation axis, a blade that functions as the reflecting surface.
VEHICULAR FORWARD VIEWING IMAGE CAPTURE SYSTEM
A vehicular forward viewing image capture system includes an accessory module configured for attachment at an in-cabin side of a windshield of a vehicle, whereby a CMOS image sensor views through the windshield forward of the vehicle. With the accessory module attached at the in-cabin side of the windshield, and while the vehicle is traveling along a road, captured image data is processed to determine movement of an object of interest viewed by the image sensor. Multiple frames of captured image data are processed in determining movement of the object of interest. The accessory module includes an electrical connector for electrically connecting to a vehicle wiring system of the vehicle. Image data captured by the image sensor may be processed for an automatic headlamp control system of the equipped vehicle. The vehicular forward viewing image capture system may compensate for misalignment of the image sensor.
