ADAPTIVE HEADLIGHT SYSTEM
A motor vehicle includes headlamps having a plurality of LED light sources, one or more processors, and a memory storing instructions. One or more processors executing the instructions are enabled to receive first data, including at least map data, indicating a road curvature upcoming along a road on which the motor vehicle is traveling. The processors are also enabled to determine a light change, the change adapting a light pattern of the headlamps in at least one of color, intensity or spatial distribution to increase light in a direction of the road curvature ahead of the motor vehicle and shaping light based at least in part on the road curvature. The processors are further enabled to control at least a first plurality of the LED light sources to provide light based at least in part on the determined light change and prior to the motor vehicle reaching the road curvature.
LIGHT BEAM PROJECTION DEVICE PROVIDED WITH SUBMATRICES OF LIGHT SOURCES, LIGHTING AND HEADLIGHT MODULE PROVIDED WITH SUCH A DEVICE
An optical light beam projection device, notably for a motor vehicle, includes upstream in the direction of propagation of the light rays, a set of at least two associated submatrices each provided with primary light sources capable of emitting light rays. Downstream, a primary optical system is provided with a plurality of convergent optics, at least one convergent optic being associated with each submatrix and arranged downstream thereof, the separation between the optical axes of two adjacent convergent optics corresponds respectively to the separation between the centers of the corresponding adjacent submatrices. Another subject of the invention is an optical module comprising the device and a motor vehicle headlight.
Interfitting adapters for lamps
First adapter (10) and second adapter (40) are each separately securable to a respective automotive light bar (200, 201) at mutually facing lateral light bar end caps (206). The adapters (10, 40) interfit, such as first adapter (10) having one or more tenons (14; 18) received in shape-conforming recess or mortise (44) of second adapter (40). The coupling assembly formed from interfit first and second adapters (10, 40) sufficiently supports a midspan region of conjoined light bars (200, 201) to permit omission of mounting L-brackets (208) conventionally required at the mutually facing light bar ends (206), thus allowing fewer holes to be drilled in vehicle roof or bumper (212) and resulting in an aesthetically cleaner presentation of the overall lengthened light bar assembly.
Circadian-friendly LED light sources
Methods and apparatus for providing circadian-friendly LED light sources are disclosed. A light source is formed to include a first LED emission (e.g., one or more LEDs emitting a first spectrum) and a second LED emission (e.g., one or more LEDs emitting a second spectrum) wherein the first and second LED emissions are combined in a first ratio and in a second ratio such that while changing from the first ratio to the second ratio the relative circadian stimulation is varied while maintaining a color rendering index above 80.
Light module for a motor vehicle comprising a plurality of light source branches
A light module for a motor vehicle, including a first electrical assembly on a first carrier, which harbours a plurality of branches that are connected in parallel, each branch including light sources, preferably light-emitting diodes. The module includes a second carrier which includes a control unit for controlling the supply of electrical power to the light sources, the control unit including a feedback loop from a reference branch. The light module allows the number of connections between the two carriers of the assembly to be decreased and reliability thereof to be increased.
Lamp for vehicle
A lamp for a vehicle includes a plurality of lamp modules. Each of the plurality of lamp modules comprises a light source unit including a light source; an optical path adjusting unit that adjusts a path of light generated from the light source unit; and a lens unit that emits the light incident from the optical path adjusting unit to form a first beam pattern. Further, the lens unit comprises an incident lens unit including a plurality of incident lenses; an emitting lens unit including a plurality of emitting lenses; and a shield unit disposed between the incident lens unit and the emitting lens unit to obstruct a portion of the light incident on the plurality of emitting lenses.
Vehicle lamp
A vehicle lamp includes: a lamp body having a front opening; a front cover attached to the lamp body to cover the front opening and configured to form a lamp chamber with the lamp body; a lamp unit including at least one light emitting element mounting portion having a heat dissipation portion, and disposed in the lamp chamber; an air blower configured to generate, in the lamp chamber, an air circulation flow including a cooling flow sent in a forward direction toward the heat dissipation portion and an intake flow returning to the rear, and an air blower support member configured to support the air blower so as to dispose the air blower behind the lamp unit in the lamp chamber, and to form an intake space through which the intake flow passes below the cooling flow.
INTERFITTING ADAPTERS FOR LAMPS
First adapter (10) and second adapter (40) are each separately securable to a respective automotive light bar (200, 201) at mutually facing lateral light bar end caps (206). The adapters (10, 40) interfit, such as first adapter (10) having one or more tenons (14; 18) received in shape-conforming recess or mortise (44) of second adapter (40). The coupling assembly formed from interfit first and second adapters (10, 40) sufficiently supports a midspan region of conjoined light bars (200, 201) to permit omission of mounting L-brackets (208) conventionally required at the mutually facing light bar ends (206), thus allowing fewer holes to be drilled in vehicle roof or bumper (212) and resulting in an aesthetically cleaner presentation of the overall lengthened light bar assembly.
METHOD OF COUPLING AUTOMOTIVE EXTERIOR LIGHT BARS
First adapter (10) and second adapter (40) are each separately securable to a respective automotive light bar (200, 201) at mutually facing lateral light bar end caps (206). The adapters (10, 40) interfit, such as first adapter (10) having one or more tenons (14; 18) received in shape-conforming recess or mortise (44) of second adapter (40). The coupling assembly formed from interfit first and second adapters (10, 40) sufficiently supports a midspan region of conjoined light bars (200, 201) to permit omission of mounting L-brackets (208) conventionally required at the mutually facing light bar ends (206), thus allowing fewer holes to be drilled in vehicle roof or bumper (212) and resulting in an aesthetically cleaner presentation of the overall lengthened light bar assembly.
Detector controlled headlight system
An automated headlight system for vehicles replaces the high and low beam with a continuum of beam patterns, with further variable spatial distribution of intensities and color spectrum. The digital-headlight is comprised of a controller, sensors and multiple, individually-controllable light-sources modified by optical-control elements to form narrow-beams which are then combined to create the overall headlamp beam. Utilizing real-time sensor data regarding beings, objects and vehicles in the way-ahead, as well as optional information on the driver, vehicle and environment, the logical controller dynamically adapts the headlight system's illumination so as to provide vehicle operators with optimal visibility while preventing discomfort-glare from reaching the eyes oncoming traffic or pedestrians.
