Problems solved by technology
[0005] However, since the conventional ceiling-embedded lighting fixtures only provided through-holes through which the ceiling-attached equipment penetrates, there is a problem that the shapes and sizes of the ceiling-attached equipment that can pass through the through-holes are limited.
[0006] In addition, since the ceiling-attached equipment must be attached not only to the ceiling-embedded lighting fixture but also to the ceiling structure above the ceiling surface, the workability of the ceiling-attached equipment is poor, and there is a problem that the ceiling-attached equipment cannot be easily changed.

PROBLEM TO BE SOLVED: To provide a ceiling embedded type luminaire 11 capable of easily changing ceiling incidental equipment 23 which is attached to a luminaire body 21. SOLUTION: An annular lamp receiving portion 22 for receiving a lamp 14 is provided in the perimeter area of a luminaire body 21 and a ceiling incidental equipment receiving portion 24 is provided in the central area in the annular lamp receiving portion 22. A ceiling incidental equipment attaching member 42 to which a ceiling incidental equipment 23 is attached is removably attached in the central area of the luminaire body 21. The ceiling incidental equipment 23 is attached to the luminaire body 21 using the ceiling incidental equipment attaching member 42 and the ceiling incidental equipment 23 is easily changed by putting on and taking off the ceiling incidental equipment attaching member 42. The ceiling incidental equipment 23 includes a cover 48, a down light etc.
Description
technical field [0001] The present invention relates to a ceiling-embedded lighting fixture to which ceiling-attached equipment can be attached, and a lighting system using the ceiling-embedded lighting fixture. Background technique [0002] In the past, ceiling-embedded lighting fixtures that are integrated with ceiling-attached equipment such as various detectors installed on the ceiling surface, fire-fighting equipment, and audio equipment, and are installed on the ceiling have been known. The ceiling-embedded lighting fixture includes a fixture body embedded in the ceiling, a reflector plate mounted in the fixture body, and a light-transmitting plate mounted on the lower opening of the fixture body. The through-hole in the center of the light plate is arranged between the reflector and the light-transmitting plate of the instrument body, and a lamp is arranged around the through-hole. [0003] On the ceiling surface, not only an embedment hole for embedment of the appli...
