Abstract: Disclosed is a system enabling micro-adjustments in headlamps having upper and lower modules. A link exists between the upper and lower modules, the length of the link is made to be adjustable. The lower module is located on a pivot so that adjustments made to the length of the link result in a desired lighting pattern.

Abstract: A control device (100) for controlling a vehicle lamp (210) provided in a vehicle is provided. The device includes: a receiver (102) configured to receive an acceleration signal representing an acceleration of the vehicle, from an acceleration sensor configured to detect the acceleration of the vehicle, wherein an inclination angle (?) of the vehicle with respect to a horizontal plane is calculated based on the acceleration signal; a controller (104) configured to: i) generate a first control signal instructing the vehicle lamp to adjust an optical axis of the vehicle lamp in response to a change of the acceleration signal, when the vehicle has already stopped; and ii) generate a second signal instructing the vehicle lamp to maintain the optical axis of the vehicle lamp, when the vehicle is traveling on a road surface.

Abstract: A headlamp in an automobile, which is rotatable about a yaw axis when negotiating a bend, has a controller for controlling the rotary movement. In order to improve the illumination of a roadway lying in front of an automobile, the controller may take into account a driving profile.

Abstract: A sliding adjuster includes a base housing with a slide positioned at least partially therein. The base housing includes mounting tabs so that the adjuster can be secured to the back of a headlamp assembly support frame. The base housing includes channels along its sides in which rails extending from the slide are disposed. A ball stud extends from the slide, the ball of which is engaged in a reflector within the headlamp assembly such that axial movement of the ball stud causes movement of the reflector. Movement of the slide is caused by rotation of an adjustment screw that is threaded into the slide but held in axial position with respect to the base housing. The adjuster may include a vehicle headlamp aiming device (“VHAD”) if required for the particular application.

Abstract: The present invention provides an adjustment mechanism by which a luminaire may be adjusted and secured along an arcuate path. The adjustment mechanism includes a mounting bracket, adjustment bolt, adjustment brace, which is attached to the optical housing of the luminaire, and a positioning means, such as an eyebolt. The adjustment bolt is threadably attached to the adjustment brace via a non-rotatable nut. The adjustment bolt, which is disposed through the positioning means, is turned in order to adjust the position of the luminaire. As the adjustment bolt turns, the non-rotatable nut, along with the adjustment brace and optical housing attached thereto, moves along the threaded shaft of the bolt. When the turning of the bolt has ceased, the non-rotatable nut, adjustment brace and optical housing are secured in position by the frictional engagement of the thread of the bolt and the thread of the nut.

Abstract: A motorized headlamp adjuster which is operably connectable to a control circuit and which is engageable with a headlamp assembly. Specifically, the headlamp adjuster includes an adjuster output shaft which is engageable with a reflector of a headlamp assembly. The headlamp adjuster includes a housing, and the adjuster output shaft extends from the housing. The adjuster output shaft preferably has a sealing member thereon which seals with the housing. Preferably, an external surface of the housing also has a sealing member thereon for engaging and sealing with the housing of the headlamp assembly when the headlamp adjuster is installed. As such, the headlamp adjuster is sealed, and seals with a headlamp housing when installed. Preferably, the headlamp adjuster does not include several complex components and is relatively easy to assemble.

Abstract: A headlamp adjustor which includes an adjustor output shaft that is engageable with a reflector of a headlamp assembly. The adjustor output shaft extends from a housing, and a worm gear generally in the housing is spur gearably engaged with the adjustor output shaft. Drive structure is engaged with the worm gear such that actuation of the drive structure causes at least a portion of the drive structure to thread into at least a portion of the worm gear, thereby causing the adjustor output shaft to translate relative to the housing and adjust the position of the headlamp reflector.

Protrusions 38 engage a groove 44 in an enlarged portion 42 of the drive member 2 on a vehicle headlamp adjusting assembly 100. Projections 36 at an upper edge angle inwardly and are constructed to snap or break off if engaged with a rim 52 on the drive member 2, if one attempts to remove apparatus 30 from the assembly 100.

Abstract: A vehicle headlight assembly includes a snapping engagement between a bezel, a housing and a lens. The snapping engagement positions all three pieces relative to each other during a manufacturing or assembly process. The light bulbs of the headlamp assembly are supported on the internally aimed reflector by bulb retainers that snappingly engage openings in the reflector. The bulbs preferably include housings that bias tab members on the bulb retainers into engagement with the reflector. The reflector is moved within the housing to direct the beam of light from the bulbs. Socket retainers snappingly engage the reflector. Ball members on conventional adjustors are received within the socket retainers so that the adjustors support the reflector within the housing and provide the ability to adjust the angular position of the bulbs and reflector relative to the remainder of the assembly.
