Apparatus for forming an asymmetric illumination beam pattern
First Claim
1. An apparatus for forming an asymmetric beam pattern for illumination generated by one or more light-emitting elements, the illumination being generated substantially in an emitting direction, said apparatus comprising:
- a first optical element optically connected with each of the one or more light-emitting elements generating illumination substantially in the emitting direction, said first optical element manipulating the illumination in a first direction, the first direction being in a plane normal to a center axis of the emitting direction;
a second optical element optically connected with one or more predetermined light-emitting elements selected from the one or more light-emitting elements, said second optical element manipulating the illumination created by the one or more predetermined light-emitting elements in a second direction, the second direction being in the plane normal to the center axis of the emitting direction and different from the first direction, the second optical element increasing beam spread in the second direction;
thereby forming an illumination beam pattern that is radially asymmetric about the center axis of the emitting direction.

Abstract
The present invention provides an apparatus for forming an asymmetric illumination beam pattern that can be advantageous when illuminating channel letters in addition to enabling the creation of cove lighting, as well as other applications benefiting from asymmetric illumination patterns. The apparatus comprises one or more light-emitting elements for creating the illumination. A first optical element is operatively associated with each of the light-emitting elements and provides a means for manipulating the illumination in a first direction. A second optical element is operatively associated with predetermined light-emitting elements and provides a means for manipulating the illumination in a second direction. Upon the interaction of the illumination with both the first and second optical elements, the illumination being created can have an asymmetric beam pattern.
