Light fixtures and multi-plane light modifying elements

A lens comprising:

• a top edge, a bottom edge, a left edge and a right edge collectively defining a lens plane;
• two raised lens sections, each raised lens section comprising:
• an elongated rectangular shape that substantially spans between the top and bottom lens edges and that is substantially parallel to the left and right lens edges;
• a substantially planar face with a light-receiving side and a light-emitting side wherein the substantially planar face defines a raised lens section plane that is elevated at a distance above the lens plane;
• two opposing edges disposed at acute angles relative to the light receiving side of the substantially planar face, wherein each edge forms an overlay attachment feature;
• the lens further comprising three substantially planar sections comprising a middle planar section disposed between the two raised sections and two outer planar sections disposed on either side of the raised lens sections;
• and
• wherein the lens is configured to modify incident light.

A lens for modifying light from a light emitting device, the lens comprising:

• a substrate defining a plane of incidence and having a first surface, the substrate comprising:
• four edges, a light emitting front side and a light receiving back side;
• two groupings of parallel and adjacent elongated linear refraction elements spanning substantially between two opposing edges of the substrate, wherein each grouping is parallel to each other and wherein each grouping is parallel to two opposing edges of the substrate, and wherein each grouping is configured to be disposed above, and parallel to a linear light source in a light emitting device, and wherein each elongated linear refraction element comprises, one or more of:
• a height variation of the first surface;
• a thickness variation of the optical film;
• a refractive index variation of the first surface;
• a refractive index variation of the optical film;
• a coating in contact with the first surface;
• and
• wherein the elongated linear refraction elements are configured to alter a transmittance angle of at least a portion of light input to the light modifying element at an incidence angle with respect to the plane of incidence.

A lens comprising:

• a substrate defining a plane of incidence and having a first surface, the substrate comprising:
• a uniform transmittance region;
• and
• at least one refraction feature pattern or shape region adjacent to the uniform transmittance region and defining a feature pattern or shape region comprising at least one refraction element, the at least one refraction element comprising one or more of:
• a height variation of the first surface;
• a thickness variation of the substrate;
• a refractive index variation of the first surface;
• a refractive index variation of the substrate;
• a coating in contact with the first surface;
• and
• wherein the at least one refraction element of the at least one refraction feature pattern or shape region is configured to alter a transmittance angle of at least a portion of light input to the lens at an incidence angle with respect to the plane of incidence.
