ABSTRACT:
A recessed overhead lighting device adapted to be encased in a mounting opening defined in a ceiling panel which is supported by ceiling joists. The lighting device includes a shade structure for supporting at least one tubular lamp and having a reflective surface and also having opposite side flanges. At least one pair of generally elongated mounting members, each having first and second end portions opposite to each other, are mounted on the shade structure. The mounting members are movable between release and set positions, but are held in the release position during insertion of the shade structure from below into the mounting opening. The mounting members are, however, pivoted towards the set position, when the shade structure is inserted from below into the mounting opening, to cause the first end portions of the mounting members to cooperate with the side flanges of the shade structure to sandwich the ceiling joists and the ceiling panel, to thereby complete fitting of the lighting device to the ceiling panel. A fixture is provided on each of the mounting members for locking the associated mounting member at the set position after the shade structure has been completely inserted into the mounting opening.
