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.
L'invention concerne un appareil pour former un motif de faisceaux lumineux asymétrique qui peut être avantageux lors de l'éclairage de lettres voies, tout en permettant la création de l'éclairage d'une anse, ainsi que d'autres applications bénéficiant de modèles d'éclairage asymétriques. L'appareil comprend un ou plusieurs éléments luminescents destinés à créer un éclairage. Un premier élément optique est associé, de manière fonctionnelle, à chaque élément luminescent et permet de manipuler l'éclairage dans une première direction. Un second élément optique est associé de manière fonctionnelle à des éléments prédéterminés luminescents et permet de manipuler l'éclairage dans une seconde direction. Lors de l'interaction de l'éclairage avec les premiers et les seconds éléments optiques, l'éclairage créé peut présenter un motif de faisceau asymétrique.
