Abstract: The headlight has a light source (10) and a reflector (12) by which light is reflected to a light guiding or deflecting device (18). The light guiding device (18) has a number, advantageousely from a few hundred to a hundred thousand, of individual reflecting elements (22) which are movable independently of each other between at least two different positions. Each reflecting element (22) is connected with an electrically operable adjusting element (26) which is controlled by a controller (30). The light reflected from the reflector (12) is reflectable from the light guide device (18) to form a light beam issuing from the lighting device. Reflected light from each reflecting element (22) in one of its positions forms a part of the light beam and does not contribute to the light beam in one of its other positions.

Abstract: The movable reflector of the headlight of a motor vehicle can be orientated by means of an orientation adjustment device located inside the body of the headlight. The orientation of the reflected light beam is controlled with the help of an adjustable graduated scale which is connected to the reflector and which can move with respect to a stationary indicator fixed to the headlight, so as to indicate the changes in orientation of the reflector. The graduated scale is set to zero by means of a manual adjustment carried out by specialized personnel using a special tool, once the reflector has been correctly orientated by means of the adjustment device. The stationary indicator and the graduated scale are located so that they are clearly visible inside the headlight, beneath the transparent cover of a porthole which can be opened in order to set the scale to zero.

Abstract: A mirror system for a vehicle includes at least one exterior mirror having a reflective element, a housing for the reflective element, a positioning device for selectively positioning the reflective element, and a light for emitting light generally downwardly from the mirror housing on an area adjacent the side of the vehicle. A control is responsive to the vehicle reverse gear selector being in reverse gear for causing the positioning device to position the reflective element to a downwardly tilted position, wherein the driver can view an area adjacent a side of the vehicle. The control actuates the light when the reflective element is in the downwardly tilted position in order to illuminate objects in that area. In a preferred embodiment, the control actuates the light through a lockout circuit which normally allows the light to be activated only when the vehicle is not operating.

Abstract: A vehicle headlamp system having optical reflector, lamp capsule, and gasket is disclosed. The vehicle headlamp system uses surfaces formed as part of the optical surface yielding located light source. As a result, the light source is more accurately positioned with respect to the reflector, and a more accurate beam pattern is formed. The lamp capsule is assisted in its location by a spring to force the capsule in proper location. The headlamp system no longer uses an O-ring to provide location, but an improved flat resilient gasket provides a sealing and locking force to maintain proper face to face coupling. The preferred lamp capsule uses a cup to shield light reflected from the press seal. The preferred lamp capsule uses a cup, and pedestal system mounting providing five axes of light source positioning. The preferred lamp capsule uses a clip coupling to join the light source holder to the plastic base.
