    摘要: 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.

    摘要: The apparatus of the Invention is a modular gas utility raceway for providing gas service within a clean room. The modular utility raceway has a front face and a back face coinciding with the inside and outside surfaces of the clean room walls. The utility raceway includes a vertically-oriented box-shaped beam that is open at the top to allow escape of any leaked gas above the ceiling of the clean room for the safety of clean room occupants. A support bracket supports gas pipes and connectors and extends above the top side of the clean room ceiling and discourages a user from blocking the open top of the box-shaped beam.
