Description

[Detailed description of the invention] [Field of industrial application] The invention relates to a direct-mounted lighting fixture.
This particularly applies to direct-mounted lighting fixtures having a plurality of lamps.

[Conventional technology]

Generally, when arranging multiple lamps in a direct-mounted lighting fixture that is directly attached to a mounting surface such as a ceiling, the power wire is drawn into the lighting fixture from the center of the lighting fixture, so the wiring inside the lighting fixture is It is necessary to avoid the central part of the lighting equipment body.

In that case, as shown in FIG. 4, electric components such as the lighting device 7 are placed around the periphery of the lighting device body 1, avoiding the center, and a bulkhead covering the lighting device 7 is placed between the reflector plate 20 attached to the lighting device body 1. 21 is integrally formed,
A lighting device is known in which the wiring inside the lighting device is housed together with the lighting device 7 and the like in a space surrounded by the lighting device main body 1 and the reflector plate 20.

Furthermore, as shown in FIG. 5, a device using a substantially cylindrical live part protection cover 22 made of a molded product or the like in place of the partition 21 integrated with the reflector 20 is also known.

[The problem that the idea aims to solve]

However, with the above configuration, if the wiring inside the lighting equipment is not securely supported from the periphery of the lighting equipment body and then the reflector or live part protection cover is attached, the wiring inside the lighting equipment will protrude and cause reflections. There was a risk that the lamp would get caught between the plate or live part protective cover and the lighting fixture body, and there were problems such as requiring a lot of man-hours for assembly.

The present invention was developed in view of the above-mentioned background, and its purpose is to secure space in the center of the lighting equipment body by securely positioning the wiring inside the lighting equipment with an inexpensive structure. Our objective is to provide direct-mounted lighting equipment.

[Means to solve the problem]

The direct-mounted lighting device according to the present invention has a plurality of lighting devices and electrical components such as switches arranged around the periphery of the lighting device body that is attached to the mounting surface, and a lead wire is connected to the power source and the electrical components. A protective cover that covers the lighting device and is attached to the lighting equipment body has at least two grooves opening toward the lighting equipment body on the side surface, and wiring is provided between the power supply and switch and electrical components other than the switch. Insert the connected lead wire into the protective cover from one of the grooves in the protective cover of the lighting device installed between the electrical component and the power source and switch, and lead it out of the protective cover from the other groove to protect it. The lead wires are positioned using a cover.

〔Example〕

1 to 3 show one embodiment of the present invention, which will be explained below based on the drawings.

As shown in FIGS. 2 and 3, this direct-mounted lighting fixture has a lighting fixture main body 1 covered with a main body cover 2, and a plurality of lighting fixtures 3 attached thereto in a substantially reflective manner.

As shown in Fig. 1, the lighting fixture main body 1 is formed of a steel plate in the shape of a substantially square plate with a downward rise on the periphery. A convex portion 4 that protrudes downward in a circular trapezoidal shape that matches the luminaire main body 1 itself.
is formed. The convex portion 4 has four daruma holes 5 formed at equal pitches on a concentric circle near its outer periphery, and a circular ceiling rosette insertion hole 6 in the center.
is drilled.

A lighting device 7 such as a high-frequency lighting device is installed near each corner of the lighting device body 1, and a protective cover 8 made of a thin steel plate is attached to the lighting device body 1 with screws 9, covering the lighting device 7. ing.
Further, a blinking switch 10 as an electric component for lighting and a night light 11 made of a neon tube are attached to the lighting fixture body 1.
and each lighting device 7 and night light 11 are individually wired and connected by lead wires 12, respectively. It is connected to an external power supply through a ceiling rosette, and one pole of the power supply is connected via a switch 10, and the other pole is directly connected to each electrical component.

The protective cover 8 that covers the lighting device 7 is formed into a substantially rectangular bowl shape by punching and bending a thin steel plate, and a main body cover for fixing the main body cover 2 is located at the center of the lighting device main body 1 on the bottom of the protective cover 8. One main body cover mounting screw hole 14 into which the mounting screw 13 is screwed is provided, and a lamp mounting screw hole 15 into which a mounting screw for mounting the lamp 3 is screwed is provided on the outer periphery of the lighting fixture housing 1. Two screws are installed on each side, and they also serve as mounting bases for the main body cover 2 and the lamp 3. Grooves 16 through which the lead wires 12 can be inserted are formed between the side surface of the protective cover 8 on the center side of the lighting device main body 1 and both side surfaces adjacent thereto. When installing, the lead wire 12 is passed through the groove, and then the protective cover 8 is attached to the lighting device main body 1. At this time, the lead wire from the switch 10 to the farthest lighting device 7 or night light 11 is
It is inserted into the groove 16 of the protective cover 8 of the lighting device 7 located halfway, and is positioned by the protective cover 8 so as not to protrude into the center of the lighting device body 1.

The protective cover 2 is formed of a substantially rectangular plate-shaped molded product that covers the lighting fixture body 1, and the body cover mounting screws 13 are inserted into the body cover mounting screw holes 14 of the protective cover 8.
It is fixed to the lighting fixture main body 1 by being screwed together.

The lamp 3 has a socket and a lamp support spring inside, and a round fluorescent lamp is attached thereto.
Protective cover 8 mounting screw holes 1
5 and is fixed to the lighting fixture main body 1.

A fixture 17 for attaching the lighting fixture main body 1 is fixed to a mounting surface such as a ceiling with two wood screws. The mounting tool 17 has locking portions 18 on the periphery opposite to each other with respect to the center and extending along the mounting surface while being spaced apart from the mounting surface.
A female thread is installed in each of the body mounting screws 19.
are screwed together. The distance between the main body mounting screws 19 matches the distance between the pair of daruma holes 5 located symmetrically with respect to the center of the lighting fixture body 1, and the head of the main body mounting screw 19 is inserted through the large diameter portion of the daruma hole 5. It is becoming more and more like this.

This direct-mounted lighting fixture is constructed as described above, and the lead wire can be reliably positioned with an inexpensive structure, and the lead wire does not protrude into the center of the lighting fixture body.

Note that if the side surface of the protective cover 8 from the center of the lighting fixture body is slightly shortened to form a gap between the protective cover 8 and the lighting fixture body 1 that is large enough for the lead wire 12 to pass through, the insertion of the lead wire 12 into the groove 16 will be made easier. This can be done after the protective cover 8 is attached to the lighting fixture body 1.

[Effect of idea]

Since the present invention is constructed as described above, the lead wire can be reliably positioned with an inexpensive structure, and the lead wire does not protrude into the center of the lighting fixture body.
