Claims

[Scope of Claim for Utility Model Registration] (1) An appliance body that has a mounting hole in the center and is directly attached to the ceiling by inserting a simple connection means with an AC power supply provided in the ceiling into the mounting hole; A dish-shaped reflector that covers the mounting hole on the bottom and the surrounding area, and is attached to the bottom of the device body so that it can be opened and closed up and down using a part of the surrounding area as a fulcrum.
A ceiling-mounted lighting fixture for an annular fluorescent lamp, comprising a fluorescent lamp lighting means housed and fixed in a dish-shaped reflector. (2) A device body that has a mounting hole in the center and is directly attached to the ceiling by inserting a simple connection means for connecting to an AC power source provided in the ceiling into the hole, and a mounting hole on the bottom of the device body and its surrounding area. The reflector plate is rotatable horizontally along the lower surface of the instrument body using the connection point with a part of the periphery of the mounting hole of the instrument body as a fulcrum. A lighting fixture for a ceiling-mounted annular fluorescent lamp, comprising a fluorescent lamp lighting means.
