The present invention is directed toward an attachment for a light fixture. More specifically, the present invention is directed toward an attachment for retaining one or more lenses in position for use with light fixtures that have a housing in which the light source is recessed. The lenses may be, for example, colorless transparent lenses, colored transparent lenses, colorless translucent lenses, colored translucent lenses, louvered grates, and diffusing grids. Further, the lenses may be made out of any material that is known in the art or has yet to be developed, but are preferably made of a rigid material such as plastic. The preferred embodiment of the present invention comprises generally an attachment body and an attachment insert. The attachment body comprises an inner sleeve, a means for retaining the inner sleeve on a recessed housing, an upper eave connected to the inner sleeve, a recessed cavity in the upper eave, and a means for securing the attachment insert to the attachment body. The attachment insert is designed to rest in the recessed cavity of the upper eave. The attachment body is adapted to have dimensions such that the inner sleeve fits inside the housing of a recessed light fixture. In addition, the inner sleeve and upper eave define voids and it is generally desirable for the inner sleeve, upper eave and voids to have dimensions such that light is permitted to pass there through. The attachment insert is removably connected to the attachment body and supports a lens. In the preferred embodiment, the attachment insert is constructed such that it retains one or more lenses substantially in the recessed cavity contained in the upper eave. The means for connecting the attachment insert to the attachment body in the preferred embodiment is a screw thread on an outer surface of the attachment insert that is compatible with a screw thread on an inner surface of the attachment body.
