Claim 10

In a luminaire including a frame, a door connected to the frame, a light-diffusing lens mounted in an aperture in the door and light-producing means enclosed by the frame, door and lens, the improvement comprising a transparent shell for protecting the lens, said shell being of hemispherical shape, disposed at the side of the lens opposite the light-producing means and spaced from the lens, and means for securing said shell to the luminaire door.

Claim 11

In the luminaire defined in claim 7, a flange projecting inward from the margin of the shell and located in a diametral plane of the shell, the inner perimeter of such flange defining an aperture of approximately the same size and shape as the aperture in the luminaire door.

Claim 12

In the luminaire defined in claim 7, the shell being spaced at least one inch (2.54 cm.) from the lens.
