Recessed canopy light fixture

A recessed canopy light having a main body positionable above an opening in a canopy sheet, a rim member in contact with the lower surface of the canopy sheet such that the sheet is sandwiched between the main body and the rim member, a lens frame below the rim member and hinged thereto, each hinge including a first member secured to the rim member and having an upwardly-open substantially semi-cylindrical female portion with an outer edge spaced below the canopy sheet by a first distance and a second member secured to the lens frame and having a truncated-cylindrical male portion engaged in the female portion, the male portion having a flat therealong such that the vertical dimension of the male portion varies between a full diameter much greater than the first distance and a truncated diameter which is at most slightly greater than the first distance, such that the male portion is non-removable from the female portion except when the lens frame is pivoted to a fully-open position beyond a vertical hanging position. Preferred embodiments include dimensioning such that deflection of the canopy sheet is necessary to allow disengagement of the hinge members.
