  • Patent number: 10766403
    Abstract: A method includes generating a first beam pattern via a headlamp assembly arranged on a motor vehicle and detecting, via a camera, an object in the first light beam pattern. The method additionally includes receiving, via an electronic controller, a signal from the camera indicative of the object, identifying the object as another motor vehicle, and determining a distance between the headlamp assembly and the other vehicle. The method also includes determining a first amount of glare the first beam pattern generates to the other vehicle at the determined distance and identifying when the first amount of glare exceeds target glare. The method further includes identifying a second beam pattern corresponding to a second amount of glare that is below the target glare and switching the headlamp assembly from generating the first beam pattern to generating the second light beam pattern.

  • Patent number: 10408706
    Abstract: A device for detecting a light beam projecting from a lamp of a vehicle is described, and includes a plurality of photo-sensors and a plurality of indicator bulbs. The photo-sensors are arranged in a linear array along a first axis, and the indicator bulbs are arranged in a linear array along a second axis that is in parallel to the first axis. A controller is in communication with the photo-sensors and the indicator bulbs. The controller includes an instruction set that is executable to monitor signal inputs from the plurality of photo-sensors to detect presence of a light beam projecting from the lamp of a vehicle, determine a cut-off gradient line for the light beam based thereon, and illuminate one of the indicator bulbs to indicate a location of the cut-off gradient line for the light beam.

  • Patent number: 10082282
    Abstract: A light-emitting diode (LED) string includes an electrically conductive wire and a plurality of LEDs. The LEDs are electrically connected to the wire in series along an axial length of the wire. The LED string may include a solder layer, with the LEDs electrically connected to the wire via the solder layer. A tube having an optional phosphor coating may circumscribe the wire and LEDs. When connected to a surface, the LED string emits light in a band of at least 180 degrees with respect to the surface. A light assembly includes a first surface and a first LED string configured as set forth above. The light assembly may include a second LED string positioned with respect to the surface and having additional LEDs configured to illuminate in response to a second control signal from the controller.

  • Patent number: 6945681
    Abstract: Headlamp assemblies utilize a solid optical body made of glass or another heat resistant, light transmissive material. The solid optical body has an axially positioned cavity therethrough which receives a bulb that injects light through a cylindrical wall of the cavity into the optical body. In order to reflect light from the bulb, the optical body has a rear surface which is coated with a reflecting material, such as aluminize or a dichroic material. In accordance with one embodiment of the invention in which a plastic lens is used, the optical body is made of glass with a dichroic coating configured so that the infrared component of light from the bulb is transmitted through the dichroic coating and emitted through the rear of the optical body. This reduces transmission of heat from the bulb to the plastic lens so that the lens can be positioned closer to the optical body, which decreases the fore/aft extent of the headlamp assemblies.
