Description

[Detailed explanation of the idea] The present invention relates to improvements in grounded lighting equipment.

The present invention will be explained below according to the embodiment of the waterproof grounding lighting fixture shown in FIGS. 1 and 2.

In the figure, reference numeral 1 denotes a metal plate substrate having a through hole 2 in the center and on which screw columns 3, 3 are protruded, and is fixed to a wall A, which is a mounting base, via a waterproof gasket 4.

Reference numeral 5 denotes a receiver that is integrally provided at the bottom of the substrate 1.

Reference numeral 6 denotes a ground wire that passes through the wall A and the through hole 2, is exposed to the surface, and is fixed to the substrate 1 via screws.

Reference numeral 7 denotes a power supply line that passes through the through hole 2 and is exposed on the surface of the wall A.

Reference numeral 8 denotes a lamp, which is comprised of a cylindrical arm portion 9 with a side opening, a globe 10 fixed to the arm portion 9, and a lamp 11 housed within the globe 10.

Reference numeral 12 denotes an internal lead wire connected to the charging portion of the lamp 8, and is exposed from the side opening of the arm portion 9.

Reference numeral 13 designates a conductive hook piece, one end of which is fixed to the lamp 8 and electrically connected to the chassis 14 and the mounting base 15, which are non-charged metal parts of the lamp, and the other end is a hook portion 13a. Located nearby.

A grounded lighting fixture with such a configuration is attached to wall A as follows.

First, as shown in FIG. 1, the lamp 8 is temporarily hung by hooking the hook portion 13a of the conductive hook piece onto the holder 5 integrally provided at the bottom of the board 1, and in this state, the lead wire 12 inside the device and the board 1 Connect it to the power supply line 7 exposed from.

At this time, since the lamp 8 is temporarily suspended, the person performing the wiring work can use both hands.

Next, while storing the connection part in the cylindrical body of the arm part 9, the open end surface of the arm part 9 is brought into contact with the gasket 4, the threaded post 3 protruding from the board 1 is passed through the arm part 9, and the nut 14 is screwed into the threaded post 3. If they are tightened together, the lamp 8 is completely fixed.

At this time, the hook portion 13a of the conductive hook piece 13 comes into elastic contact with the substrate 1, so that the lamp 8 is electrically connected to the ground wire 6.

As described above, the grounding lighting fixture of the present invention is designed so that a conductive hook piece is provided to temporarily suspend the light fixture, and when the light fixture is permanently fixed, the conductive hook piece naturally conducts to the ground wire. Therefore, it was possible to provide a lighting fixture with a grounding device, which facilitates the connection work between the power supply line and the lead wire inside the fixture, and also allows easy grounding.
