US Patent 10344952 Recessed light-emitting diode lighting fixture

A recessed lighting fixture comprises a generally annular body having a central cavity in the form of a partially spherical socket. There is a lighting support member having a partially spherical exterior portion which is closely fitted within the partially spherical socket of the annular body. The lighting support member is pivotable relative to the annular body, but air flow between the partially spherical socket of the annular body and the partially spherical exterior portion of the lighting support member is substantially restricted. There may be a light source mounted to the lighting support member adjacent a bottom thereof. The light source may be a light-emitting diode.
