Claim 0:
1. A recessed concrete luminaire installed inside a recess formed in a concrete mounting structure, the concrete mounting structure having an exposed surface that is flush with at least one of a ceiling, a floor, or at least one side wall of a building structure, the recessed concrete luminaire comprising:
a) at least one junction box defining a housing for retaining at least one light emitter and corresponding electrical hardware components; and
b) a concrete base structure made of concrete and secured to the at least one junction box, the concrete base structure having a first side connected to the at least one junction box and an opposed second side, the concrete base structure further comprising at least one light opening passage having a corresponding profile shape extending between the first and the second sides,
wherein, in an installed position, the at least one light emitter is spaced from the second side of the concrete base structure such that light from the at least one light emitter passes through the profile shape of the corresponding at least one light opening passage through the concrete base structure, and
wherein, in the installed position,
the recessed concrete luminaire is irremovably embedded inside the recess formed in the concrete mounting structure,
the second side of the concrete base structure is exposed outside of the recess and is flush with the exposed surface of the concrete mounting structure, and
the at least one light emitter is accessible from the corresponding at least one light opening passage of the concrete base structure.
