Abstract
A lens system including one or more insertable lenses that are secured from movement relative to a protective transparent media that itself is securable to a lighting enclosure with a light source in the lighting enclosure. The insertable lenses can be removable or alternately oriented to alter the distribution of light or the projection direction of light, respectively.
Claims20
A lens system for a lighting enclosure, said lighting enclosure including a plurality of light source modules, said lens system comprising:
- a transparent media removably attachable to the lighting enclosure, the transparent media including a substantially smooth media surface and a surface edge extending substantially perpendicularly away from the media surface;
- and
- at least two insertable lenses attached to the transparent media, the insertable lenses each including a substantially smooth lens surface contacting the media surface and a negative edge contacting the surface edge to deter movement of the insertable lenses relative to the transparent media;
- wherein one of the at least two insertable lenses is selected from lenses consisting of, Fresnel, collimating, and focusing lenses and another of the at least two insertable lenses are selected from the group consisting of Lambertion, scattering, and diffusing lenses;
- wherein the lighting enclosure has at least one lighting characteristic selected from the group consisting of collimated light or diffused light;
- and wherein the lighting enclosure has a first lighting direction projection and a second lighting direction projection different than the first lighting direction projection.
A lens system for a lighting enclosure, said lighting enclosure including a plurality of light source modules, said lens system comprising:
- a transparent media including a media surface and a surface edge extending substantially perpendicularly away from the media surface, the transparent media removably attachable to the lighting enclosure;
- and
- at least two insertable lenses attached to the transparent media, the at least two insertable lenses positioned in contact with the media surface, in contact with the surface edge, and deterred from lateral movement by the contact;
- wherein one of the at least two insertable lenses is selected from the lenses consisting of, Fresnel, collimating, and focusing lenses and another of the at least two insertable lenses is selected from the group consisting of Lambertion, scattering, and diffusing lenses;
- wherein the lighting enclosure has at least one lighting characteristic selected from a group consisting of collimated light or diffused light;
- and wherein the lighting enclosure has a first lighting direction projection and a second lighting direction projection different than the first lighting direction projection.
A method of changing the lighting characteristics of a lighting enclosure that has a plurality of light source modules, the method comprising:
- attaching substantially smooth lens surfaces of at least two lenses, respectively, to a substantially smooth surface of a transparent media that is removably attachable to the lighting enclosure, such that a negative edge of the at least two lenses contact a surface edge of the transparent media;
- wherein one of the at least two lenses is selected from lenses consisting of Fresnel, collimating, and focusing lenses and another of the at least two lenses is selected from lenses consisting of Lambertion, scattering and diffusing lenses;
- and wherein the lighting characteristic is selected from the group consisting of collimated light or diffused light;
- and
- attaching the transparent media to the lighting enclosure after attaching the at least two lenses to the transparent media, the lighting enclosure having a first lighting direction projection and a second lighting direction projection different than the first lighting direction projection.
