Claims

[Scope of Claim for Utility Model Registration] (1) A bottomed cylindrical appliance case embedded in the ceiling and opening downward, a lamp disposed in the center of the appliance case, and a lamp attached to the lower opening edge of the appliance case. A lighting fixture comprising a bowl-shaped reflector that reflects lamp light downward, and a lighting device that lights the lamp in a space formed by the fixture case and the reflector. (2) The above-mentioned lighting device is constructed of copper-iron type, and the mounting brackets are installed so that the ballast and glow lamp that make up the lighting device are located sufficiently far from each other and isolated from the top plate and sides of the appliance case. The lighting device according to claim 1, which is attached to the device case via a lighting device. (3) The above lighting device is composed of an inverter type,
2. The lighting device according to claim 1, wherein a heat generating component of the lighting device is arranged close to or in contact with a side wall of the device case. (4) A practical device characterized by arranging large components such as a transformer and heat-generating components such as a transistor with a heat sink on the outer periphery of a printed circuit board so that the components are in contact with or close to the side wall of the device case. A lighting fixture according to claim 3 of the patent registration claim.
