Recessed luminaire with shuttle mechanism for access to electrical components

摘要

A recessed down-light fixture having a housing with a light source aperture, a control gear assembly containing control gear, and a guidance system that allows the control gear assembly to slide and align with the light source aperture. The aperture enables passage of a light source through a barrier such as a ceiling. The housing includes a latching or locking device for release and passage of components through the aperture for maintenance or re-lamping. The control gear assembly, or internal wiring compartment, includes a stop that secures the shuttle in a position above the aperture. The control gear assembly can then be detached and pass through the aperture, providing access to electrical components and splices within the assembly. A trim ring having a concealable surface is mounted around the aperture to increase the structural integrity of the aperture, allow for plastering and painting, and to provide a finished appearance.
