DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for mounting a lighting fixture on a distribution duct.

[0002]

2. Description of the Related Art When a lighting fixture is mounted on a power distribution duct fixed to a ceiling, there has been a power receiving plug type suitable for a spotlight for a store.

[0003]

However, it is not considered to attach a ceiling light fixture for general household use. The present invention has been made in view of such problems to be solved, and an object of the present invention is to provide a device for attaching a ceiling-mounted lighting fixture to a power distribution duct.

[0004]

Means for solving the problems are as described in the claims.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described. However, this is merely an exemplary embodiment adopted based on the present invention, and the present invention is described based on matters specific to the embodiment. Therefore, the technical scope of the present invention should be determined based on the matters stated in the claims and matters substantially equivalent to the matters.

The illustrated embodiment is a lighting fixture mounting device which is mounted on a power distribution duct 2 fixed to a ceiling 1 via a mounting adapter 3 and receives power. On the upper surface of the mounting adapter 3, a pair of conductive blades 5, 5, which can be brought into contact with a pair of power distribution rails 4, 4 in the power distribution duct 2 by being inserted into the lower surface opening of the power distribution duct 2 and inside the power distribution duct 2. The mounting adapter 3 has a pair of mounting pieces 7, 7 which are locked by the pair of grooves 6, 6. Is provided with a power supply unit 10 for the lighting fixture 8.

More specifically, the power distribution duct 2 has a long groove shape and is embedded and fixed in the ceiling 1 so that the lower surface thereof is flush with the lower surface of the ceiling 1. The lighting fixture 8 is provided with a pair of locked pieces 11 to be locked to the locking portions 9 of the mounting adapter 3 at the center opening of the upper surface thereof. After retreating outward against the inward biasing force of the spring 12, the spring 12 is again displaced inward and locked by the locking portion 9.

[0008] Then, the hooking plug 13, which is cord-connected (not shown) from the lighting fixture 8 side, is pivotally connected to the power supply unit 10 so that the lighting fixture 8 receives power. In addition, 14 is a fluorescent lamp, 15 is a glove which covers the fluorescent lamp 14 and the lower surface of the lighting fixture 8. Also, when removing the lighting fixture 8,
It is preferable to release the lock between the locking portion 9 and the locked piece 11 by displacing the release lever 16 projecting downward from the locked piece 11 outward.

According to this embodiment, it is possible to provide a device for attaching a lighting fixture 8 for home use with a ceiling directly to the power distribution duct 2, and it is easy to change the position of the lighting fixture 8 and increase the number of lights in one room.
In addition, as a lighting fixture, a cord-hanging type may be suspended from the power supply unit 10 via a so-called hook plug.
