Abstract

PURPOSE:To facilitate direct installation of a luminaire using a hook ceiling. CONSTITUTION:A through hole is formed in the center portion of a luminaire main body 21 and an inverter unit 24 is secured around the through hole. A hook hole 26 is formed through the lower surface portion 25 of the inverter unit 24. A connector 41 is provided with a hook 46 for engaging in the hook hole 15 of a hook ceiling 12 and a connection fitting 51 for engaging in the hook hole 26 of the inverter unit 24, and the hook 46 is electrically connected to the connection fitting 51. Mechanical coupling of the luminaire main body 21 and the hook ceiling 12 and electrical connection of the hook ceiling 12 and the inverter unit 24 are simultaneously achieved by rotating only the connector 41. Therefore, the luminaire main body 21 itself is not rotated and so does not cause flawing of the ceiling surface 11.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting fixture for mounting a main body of a fixture using a hook ceiling installed on a fixture mounting portion such as a ceiling surface.

[0002]

2. Description of the Related Art Conventionally, there has been known a structure in which a lighting fixture is mounted by using a hook ceiling which is previously installed on a fixture mounting portion such as a ceiling surface.

That is, with the pair of hooking holes provided in the hook ceiling inserted with the pair of hooking claws protruding from the mounting portion provided in the central portion of the tool body, the tool body is predetermined in a predetermined direction. By pivoting at an angle, the attachment portion of the instrument body is mechanically and electrically connected to the hook ceiling.

However, according to such a configuration,
When directly attaching the lighting fixture to the fixture mounting part such as the ceiling surface, when the fixture main body rotates, the fixture main body slides on the ceiling surface and scratches the ceiling surface, or There is a problem that the turning operation itself may be difficult depending on the shape.

Further, conventionally, in a lighting fixture installed directly on the ceiling surface, with a fixture body screwed to the ceiling surface, a fitting provided at the tip of an electric wire led out from a lighting device of the fixture body. There is known a configuration in which a lighting fixture is directly attached to the ceiling surface by electrically connecting the part to a hook ceiling installed on the ceiling surface.

However, according to such a configuration,
The mechanical connection work of the fixture body and the electrical connection work of the lighting device are required separately, which complicates the installation work, and connects the lighting device and the fastening part with an electric wire in the manufacturing process. However, there is a problem that the work efficiency is poor.

[0007]

As described above, according to the structure in which the attachment portion of the instrument body is mechanically and electrically connected to the hook ceiling, the instrument body slides on the ceiling surface when the instrument body is rotated. There is a problem that the ceiling surface may be scratched by the contact and the turning operation itself may be difficult.

Further, according to the structure in which the fixture body is screwed to the fixture mounting portion, the mechanical connection work of the fixture body and the electrical connection work of the lighting device are separately required, which makes the installation work complicated. At the same time, in the manufacturing process, there is a problem that wiring work is required to connect the lighting device and the engaging portion with an electric wire, resulting in poor work efficiency.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a lighting fixture which can mechanically and electrically connect the fixture body to the hook ceiling without rotating the fixture body. .

[0010]

According to a first aspect of the present invention, there is provided a lighting fixture which is mechanically and electrically connected to a fixture main body provided with a lighting device and a hooking ceiling installed in a fixture mounting portion by a rotating operation. And a connector provided with an attachment portion mechanically connected to the fixture main body by the turning operation and electrically connected to the lighting device.

According to a second aspect of the present invention, in the lighting fixture according to the first aspect, an abutting portion for the fixture mounting portion is provided on the fixture main body, and the connector body is elastic to press the fixture main body toward the fixture mounting portion. It has a body.

[0012]

In the luminaire according to the first aspect of the present invention, the connection body is rotated in a predetermined direction by a predetermined angle in a state where the main body of the equipment is held at a predetermined position with respect to the hook ceiling, and the attachment portion of the connection body is used as the hook ceiling. When hooked and mechanically and electrically connected to each other, at the same time, the fixture mounting portion of the connector is mechanically connected to the fixture body and electrically connected to the lighting device. In this state, the instrument body is attached and fixed to the hook ceiling via the connection body, and the hook ceiling and the lighting device are electrically connected via the connection body.

In addition to the operation of claim 1, in the luminaire according to claim 2, the urging force of the elastic body presses the luminaire main body against the luminaire mounting portion, and the abutting portion of the luminaire main body contacts the luminaire mounting portion. Thus, the instrument body can be installed directly and directly on the instrument attachment part without rattling.
