  • Patent number: 7144141
    Abstract: A self-aim light device. The light device includes a rotating light shield pivotally coupled to an axis. The light shield could include a mass on one end such that gravitational forces control movement of the light shield around a pivot point. The light device may be positioned within a vehicle and the light shield allows for self-aiming of a light output to conform to movement of the vehicle due to a gravitational force.
    Type: Grant

  • Patent number: 7059754
    Abstract: A modular automotive light device is provided. The light device may include multiple light emitting diodes (LED). Multiple light devices may be arranged in a desired manner comprising an automotive headlamp, for example. The light devices may be stacked on top of each other and/or positioned side by side to form the headlamp. Using multiple light devices provides a sufficient amount of radiated light rays in order to comply with regulations and standards for light output of light devices for use on the exterior of an automobile, for example.

  • Patent number: 6953261
    Abstract: A tubular reflector for reflecting light emanating from a tubular light source. The tubular reflector may be semi-circular or elliptical in shape and positioned around the tubular light source. Furthermore, the inner reflective surface of the tubular reflector may be smooth or multi-faceted. The reflector may reflect light from the tubular light source and redirect the light to achieve a desired distribution pattern.

  • Patent number: 6623132
    Abstract: A display device and a lighting system is provided for providing lighting in exterior and interior lighting applications, such as for center high mount stop lights (CHMSL) and other automotive lighting applications. The display device uses a light guide having light couplers hingedly attached to a light source end for receiving light from at least one light source. The light guide extends from the light source end with a light emitting surface and a light guide surface opposite the light emitting surface. The light emitting surface and the light guide surface extend in a direction substantially parallel to the direction of the light received from the light source. The light guide surface has a plurality of surface sections extending at angles relative to one another. The surface sections may be angled at alternating sections to direct light towards the light emitting surface using total internal reflection.

  • Patent number: 6007224
    Abstract: A reflector for a headlamp is divided into zones depending on the sizes of the light source images produced by the various parts of the reflector. Those parts of the reflector that provide smaller image sizes are used to supply light to the higher intensity parts of the road pattern. This allows greater control over glare and is particularly useful for headlamps having high intensity discharge as a light source. In one embodiment, a larger reflector is trimmed to be smaller and yet to retain portions that provide the small light source images.

  • Patent number: 5390265
    Abstract: An optical coupler is provided which includes a light source; a conduit spaced from the light source with a major axis intersecting the light source, the conduit having a circular opening for receiving light from the light source; a first reflector surface of a partial rotated ellipse positioned to place the light source at the focus of the ellipse, the first surface having an extreme end with a first angle between the focus of the ellipse and the extreme end; and a second reflector surface juxtaposed between the first reflector surface and the conduit, the second reflector surface being generated from a compound parabola with a focus along the circular opening of the conduit with a parabolic axis at an angle generally equal to the first angle from the major axis of the cable rotated along the major axis of the cable.

  • Patent number: 5197792
    Abstract: A device for providing large area uniform illumination of display panels comprises a light transmitting member including a light receiver for receiving light from a light source and reflecting that light within the light transmitting member in at least a first direction parallel to a first axis and parallel to the plane of the light transmitting member. A plurality of first reflectors reflect a first portion of the light from the first direction to an exit direction orthogonal to the plane of the light transmitting member and reflect a second portion of the light from the first direction to a second direction parallel to the plane of the light transmitting member and parallel to a second axis that is perpendicular to the first axis. A plurality of second light reflectors reflect the light from the second direction to the exit direction.
