Abstract: A structural light fixture for the ceiling of clean room, such as a clean room for pharmaceutical or electronic research or production, includes an outer U-shaped beam and an inner U-shaped beam. The inner U-shaped beam nests within the outer U-shaped beam. The inner and outer U-shaped beams are mutually reinforcing so that the combination of the two U-shaped beams is stronger and stiffer than either U-shaped beam alone. The top side of the outer U-shaped beam is exposed to the outside of the clean room and includes no perforations so that the outer U-shaped beam is a barrier to gas, particulates, microorganisms or disinfectants that otherwise would pass through the clean room ceiling. The removable inner U-shaped beam includes a lamp and power supply, allowing maintenance of the structural light fixture from the interior of the clean room without interrupting the barrier to contamination created by the structural light fixture.
