[0002]

2. Description of the Related Art Conventionally, in a simple mounting type lighting apparatus using an adapter mounted on a hanging ceiling, an adapter is electrically and mechanically connected to a hanging ceiling installed on a ceiling surface, and the main body of the equipment is connected to the adapter. Is mechanically attached, and the cord pulled out of the adapter is electrically connected to an adapter connection connector provided on the instrument side (reflector). As described above, by using the adapter, the appliance body can be installed at a fixed position on the ceiling surface in correspondence with both the embedded hooking ceiling having a low protruding height and the rectangular hooking ceiling having a high protruding height. .

[0003] A reflector having a built-in lighting device and a connector for connecting an adapter is provided on the lower surface of the appliance main body, and an opening for engaging the adapter is formed in the appliance main body and the reflector so as to communicate with each other. I have. And when the opening of the instrument body and the reflector is engaged with the adapter,
The cord of the adapter is pulled out to the lower surface side of the reflector through the opening, and the cord is connected to the adapter connector of the reflector.

Further, for example, in a lighting fixture of a direct mounting type which is directly attached to a ceiling surface, a fixture body is joined to the ceiling surface and screwed, and a power line led out from the ceiling surface is placed on a lower surface side of the fixture body. The device is pulled in and connected to a terminal block provided on the lower surface of the instrument body. An attachment hole for screwing and an electric wire inlet are formed in the instrument body.

[0005]

By the way, in a lighting device of a simple mounting type using an adapter mounted on a hooking ceiling, a mounting hole or an electric wire inlet is formed instead of the opening formed in the device main body. Therefore, when considering the construction of a direct-mounted lighting fixture, it is necessary to arrange a terminal block on the fixture body and connect the power line drawn from the wire entry through the opening of the reflector to the terminal block. Become.

However, since the terminal block has a relatively large size and shape, there is a case where an installation space cannot be taken up in the equipment main body in which the reflector is provided, and if the installation space is secured in advance, the equipment main body becomes large in the width direction. There is a problem of shaping. further,
Since the power line drawn from the opening of the reflector is connected to the terminal block of the appliance body across the reflection surface side of the reflector, there is a problem that the shadow of the power line is easily reflected on the shade covering the lower surface of the appliance body.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and a reflector can be shared between a simple mounting type using an adapter and a direct mounting type. Can improve the operability of connector connection to the adapter connection connector, and in the case of the direct mounting type, the power supply line connected to the terminal block is not routed on the reflective surface side of the reflector, An object of the present invention is to provide a lighting device that can prevent a shadow of a line from being reflected on a shade.

[0008]
