  • Patent number: 6824284
    Abstract: A lamp assembly including a number of light sources each utilized in conjunction with an optical element. The optical elements include a body of light transmitting material which further includes a top surface, a bottom surface, a front surface and a plurality of facets. The facets receive light through the front surface and reflect light through the top surface. The assembly further includes a manifold defined by the optical elements. When viewed in a direction toward the top surface, a majority of the optical elements have a common shape, preferably a pie wedge shape.

  • Publication number: 20040080835
    Abstract: A lens assembly is disclosed for use with various light emitting sources. The lens assembly includes a central section and an outer section. The central section is radially centered on an optical axis. The outer section radially surrounds the central section and is radially centered on the optical axis. The outer section includes an outer wall that has a generally rotated parabolic shape, an inner wall that abuts the central section, and a slanted front surface extending between the inner wall and the outer wall. The front surface is the area of the lens assembly axially farthest away from the light emitting source.

  • Patent number: 5779341
    Abstract: 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.

  • Patent number: 5692827
    Abstract: A rear lighting system includes an elongated light source emitting light and a solid lens having an inner surface comprised of a hyperbolic cylinder, said hyperbolic cylinder having a first focal line and a second focal line and a cylinder length. The first focal line is coincident with the light source and the outer surface is comprised of a generally planar shape perpendicular to the horizontal plane and the vertical plane.
