A method and apparatus for a lighting and/or mechanical system

摘要

The present invention pertains to a system (10) for holding equipment (12) in a ceiling (14). The system (10) comprises a first side member (16). The system comprises a second side member (18) in spaced relation with the first side member (16). The first side and second side members define a length between them. The system (10) comprises a connecting member (20) which attaches to the first (16) side and second (18) side members and connects the first side member (16) with the second side member (18). The length between the first side member (16) and second side member (18) is variable and defined by the length of the connecting member (20). The first side member (16) and second side member (18) and connecting member (20) are distinct from each other. The present invention pertains to a method for forming a lighting system (10) comprising the steps of attaching a top plate (34) to a first main profile (26) and a second main profile (32) in parallel and spaced relation with the first main profile (26) to define a trough (102). Each main profile has a bottom (30). Then there is the step of connecting a trim (22) or trimless (24) profile in proximity to the bottom end (30) of each main profile. Next there is the step of installing a lighting fixture (40) in the trough (102).
