A light source valve 2 is disposed on a non-effective reflecting surface 13 of a reflector 1, and a movable shade 3 is disposed around the light source valve 2 such that the movable shade 3 can rotate between a first position and a second position. The non-effective reflecting surface 13 of the reflector 1 is provided with a first reflecting surface 11 for forming a low bend beam light distribution pattern LBP and a second reflecting surface for forming a high bend beam light distribution pattern HBP.

A headlight, having a bowel shaped reflector with two focal points and a lens, includes a screen shaft positioned between the lens and the reflector, a rotational axis of which extends horizontally and at a right angle to an optical axis. The screen shaft is adjustable to a plurality of rotational positions and has in each rotational position a focal line, which produces a light-dark border of a light pattern. A mantle surface of the screen shaft has at least one surface portion which connects two focal lines which extends irregularly to, and deviates from, a cylindrical surface.

A vehicle headlamp control method and apparatus includes providing an imaging sensor that senses light in spatially separated regions of a field of view forward of the vehicle. Light levels sensed in individual regions of the field of view are evaluated in order to identify light sources of interest, such as oncoming headlights and leading taillights. The vehicle's headlights are controlled in response to identifying such particular light sources or absence of such light sources. Spectral signatures of light sources may be examined in order to determine if the spectral signature matches that of particular light sources such as the spectral signatures of headlights or taillights. Sensed light levels may also be evaluated for their spatial distribution in order to identify light sources of interest.

An autopilot for a flight vehicle is described herein. Various configurations of the autopilot may be used in a gyro-less guidance and control system, which can be designed based on translational acceleration measurements only. In other configurations, the one or more components of the autopilot may be used as a backup to primary components of a guidance and control system. The autopilot may use state estimates to determine effector commands to control a flight vehicle.

The invention relates to a light distribution control method and a light distribution control device in which plural illumination regions are arranged in the left-right direction and illuminated by a headlamp in an ADB light distribution pattern, and vehicle positions of a vehicle ahead are detected and selected ones of the plural illumination regions are reduced in light quantity according to the detected vehicle positions. In this method and device, corrected vehicle positions are set that are obtained by adding margins to the detected vehicle positions in the left and right directions, respectively, and compared with the plural illumination regions. Illumination regions where the vehicle ahead exists are reduced in light quantity.
摘要:
A distribution pattern of the vehicle headlight is transitioned according to a vehicle speed, between three light distribution patterns. The patterns are a normal mode corresponding to a light distribution variable control state, an OFF mode corresponding to a low-beam state, and a residential mode corresponding to a high-beam light distribution that does not give a glare to pedestrians. It is determined whether or not a detected vehicle speed is within a predetermined range that enables transition of the light distribution pattern to the residential mode, and it is determined whether or not an immediately-preceding execution state of the light distribution pattern has been the normal mode. Transition between modes of the light distribution pattern is prohibited when a detected vehicle speed is determined to be within a predetermined range, and the immediately-preceding execution state is determined to have been the normal mode.

Disclosed is a vehicle lamp a pair of lamp modules configured to irradiate light to form a pair of left and right light distribution patterns. Each of the lamp modules includes first and second lamp units. Further, irradiation light from the first lamp unit forms a first light distribution pattern having a vertically extending cutoff line at a center side of a pair of left and right distribution patterns, and irradiation light from the second lamp unit forms a second light distribution pattern near the cutoff line. The second light distribution pattern is smaller and brighter than the first light distribution pattern.

An apparatus and a method for controlling a head lamp of a vehicle are disclosed. The apparatus includes one or more processors configured to: determine whether at least one of a low beam and a high beam is turned on; select at least one of a plurality of pieces of control information for controlling an illumination pattern according to the determination result; and control the illumination pattern according to the selected control information.

A device includes a light source, a sensor, and a controller. The light source includes at least one light emitting device connected to a mount. The light emitting device comprises a plurality of segments with neighboring segments spaced less than 200 microns apart. In some embodiments, the plurality of segments are grown on a single growth substrate. Each segment includes a III-nitride light emitting layer disposed between an n-type region and a p-type region. The mount is configured such that at least two segments may be independently activated. The controller is coupled between the sensor and the mount. The controller is operable to receive an input from the sensor and based on the input, selectively illuminate at least one segment in the light source.
