Abstract
A device having an inner surface with a combination of reflective and refractive surface facets swept about an axis of revolution perpendicular to the optical axis of the device. The outer surface has a non-planar, non-circular, non-spherical shape. This outer surface generates an appropriate intensity distribution in a direction generally parallel to the major axis of the output rectangle and may also distribute energy generally parallelly to the minor axis of the output rectangle as well.

An optic comprising:
- a lens having an optical axis and a revolved inner surface revolved about an axis perpendicular to the optical axis, and further having a complex outer surface;
- a wide output light source generating energy to and through said revolved inner surface and said complex outer surface to create a rectangular output distribution having angular limits of greater than 110 degrees on a first horizontal plane and less than 40 degrees as measured on a second vertical plane that is orthogonal to the first horizontal plane.
An optic comprising:
- a lens having a revolved inner surface and a complex outer surface, wherein the inner surface is swept in a continuous arc about an axis of revolution perpendicular to the optical axis of the lens;
- and
- a light source generating light of less than about 7 lumens in intensity towards said inner surface of said lens such that the output distribution of light from said lens is a HAR rectangular output distribution with a first axis greater than about 180 degrees measured in a first horizontal plane and a second axis greater than 40 degrees measured in a second vertical plane perpendicular to the first horizontal plane that meets the PC sidemarker clearance lamp requirements of FMVSS 108 regulations for year 2008.
A device for creating a predetermined light output distribution having a substantially rectangular shape in angle space, comprising:
- a light source having a energy output angle greater than 100 degrees;
- and
- a lens having an optical axis:
- a group of inner light collecting lens surfaces, wherein said surfaces are defined by a combination of reflective and refractive surface facets swept in a continuous arc about an axis of revolution perpendicular to the optical axis of the lens;
- and
- a second complex outer lens surface having a non-planar, non-circular, non-spherical shape, for redistributing the light source energy into a rectangular output distribution having angular limits of greater than 110 degrees on a first independent horizontal plane and less than 40 degrees on a second dependent vertical plane of rotation.
