Abstract
A lens assembly for use with a light source and including an inner lens and a light directing portion. The inner lens collects light rays from the light source through a light-collecting face and emits at least a portion of the light rays radially through a series of collimators. The light directing portion may be an outer lens having light-collecting faces and light-distributing faces. The light-collecting faces correspond with the collimators and distribute the light rays through light-distributing faces. The light direction portion may alternatively be an outer reflector. The reflector has a plurality of light-reflecting surfaces, corresponding to the collimators, and configured to reflect the light rays emitted from the collimators.
