摘要： Headlamp system for an automotive vehicle has an individual lamp for illuminating a high intensity zone and a spread zone of an image surface. The system includes a first light source having a substantially elliptical reflector for directing light to a spread light zone on an image surface and a second light source having a filament mounted in an axial direction to the length. A second reflector has a generally elliptical shape, a first focus, a second focus and a magnification. The second reflector directs light to a high intensity zone on the image surface. A light shield having a generally planar surface is mounted substantially normal to the longitudinal axis substantially at the second focus. An aspheric lens having an aperture having a width is located between the shield and image surface. The maximum magnification of the filament at the aspheric lens is substantially the width of the aperture.

摘要： A central lighting system for providing light to locations remote from the light source includes first and second ellipsoidally shaped reflector members joined so as to substantially surround the light source. The reflector members collect the light output and focus it onto an input face of either a light guide or a non-imaging optical coupling member. If the optical coupling member is utilized, an angle to area conversion occurs so as to allow light introduced at high angles to an input face of the optical coupler to exit the optical coupler at a smaller angle. The reflector members can also be configured so that respective second optical focal points can reside at the apex of the opposing reflector member thereby allowing for a coupling efficiency of approximately 70% or greater.

摘要： A reduced package depth low profile headlamp includes a light source emitting light in an elongated shape with a length longer than a width. The length forms a predetermined angle with respect to the horizontal axis to generate light within predetermined a cutoff. A converging lens receiving light from the light source has an optical axis. The lens has a spherical inner surface with a center and an elliptical outer surface having a first and second focal point. The light source is positioned substantially on the optical axis so that the light source is substantially at the center of the spherical inner surface and the first focal point of the elliptical outer surface is substantially coincident with the center of the spherical inner surface.

摘要： A headlamp aiming system is provided for aiming a headlamp of a vehicle. An aimer includes a CCD camera for receiving illumination produced by the headlamp to produce a beam pattern image. A controller receives the beam pattern image from the aimer to determine an aiming correction to move the detected beam pattern to a predetermined position. An adjuster is operatively coupled to the vehicle for executing adjustments of the headlamp in response to the aiming correction. The CCD camera captures an initial image using an initial exposure time, measures a light accumulation value corresponding to the initial image, determines a final exposure time in response to the measured light accumulation value and a predetermined light accumulation value, and captures the beam pattern image using the final exposure time.

摘要： The lighting system for an automotive vehicle has uses smooth conic section solids to form a beam pattern. In one aspect of the invention the A/C ratio of the conic section solids are varied to collimate the light emitted in the vertical direction and spread light in the horizontal direction. In another aspect of the invention the A/C ratio of a hyperbolic conic section may remain the same while adding fluting to the outer surface of the lens to provide beam redirection.

摘要： A light engine combines light of first, second, and third color ranges using three pentagonal prism elements. Each prism has first and second diagonal surfaces. Each first diagonal surface has a first dichroic treatment and each second diagonal surface has a second dichroic treatment. The prisms are arranged with the first diagonal surface of the first prism juxtaposed with one diagonal surface of the third prism and with the second diagonal surface of the second prism juxtaposed with the other diagonal surface of the third prism. A first light beam of the first color is reflected at a right angle by the first diagonal surfaces, and a second light beam is reflected at a right angle by the second diagonal surfaces. A third light beam of the third color passes unreflected through the surfaces to produce a combined light beam or common output light path.
