A luminaire for indoor area lighting is provided with an intermediate member for at least diffusing and optionally distributing light emitted from a high intensity light source onto a prismatic lens, with means for diffusing light reflected by the luminaire housing, with the refractor and the intermediate member having such a relationship to each other that the efficiency of the luminaire will be increased and the temperature of the exterior refractor is minimized permitting fabrication thereof from plastic. |
