Edge lit luminaires for windows

摘要

A luminaire is provided that is configured as a window having a light guide with one or more light sources coupled to one or more edges of the light guide. Light emitted from the light guide can be used e.g., to supplement natural light passing through the window or to provide illumination when natural light is not available. Because the light source (or light sources) is incorporated into the window along one or more edges of the light guide, the light source can be either partially or totally concealed from view so as to create an appearance that can have aesthetic advantages. For example, exemplary embodiments of the present invention can have an appearance that is the same or similar to a conventional window/skylight.
