Luminaire mounting structure

摘要

A mounting structure for an outdoor luminaire adapted to mount on a tubular mast. The structure has a discontinuous tubular bore comprised of two axially spaced apart semi circular sections forming the top of the bore and a bottom semi circular section spaced midway between the two upper sections. The bore structure is integral to the housing with the inner top section adjoining an enclosing face on the housing terminating said bore. One or more of said sections includes a central boss for receiving a set screw therein adapted to bear against the mast and prevent relative movement between the housing and mast.
