Description

[Detailed Description of the Invention] The present invention relates to a fluorescent lighting fixture, and more particularly to a direct-ceiling type fixture that can be easily attached to a ceiling or the like.

Generally, installation work for lighting equipment is carried out in an upward facing position, which results in poor work efficiency for workers, and if the upward facing position continues for a long period of time, workers feel considerable physical fatigue.

Therefore, in order to reduce worker fatigue, it is necessary to shorten the time required for upward work when installing lighting equipment.

In view of the above points, an object of the present invention is to reduce worker fatigue, improve work efficiency, and shorten upward work time when installing lighting equipment.

The present invention involves forming a groove of an appropriately shaped groove on the back of the appliance body, attaching a feed wiring that electrically connects to the adjacent appliance body in the groove, and attaching a mounting bracket that adjustably attaches the groove to the ceiling or the like. It is designed to fit.

The present invention will be described below with reference to embodiments shown in FIGS. 1 to 4.

In the figure, reference numeral 1 denotes a main body of the instrument, on the back of which a groove of an appropriate shape, for example a groove 1a with a shape in which both side surfaces expand from the outside to the inside, is formed from one side in the longitudinal direction to the other side, and the groove 1a is Feed wiring 2 for electrical connection with the appliance body adjacent to both sides of the bottom;
2' is surrounded by an insulator 7 and passed through.

The insulator 7 surrounds the feed wires 2, 2' so as to cover them, for example, from above, and has its end portion 7a in contact with the bottom of the groove 1a of the instrument main body 1, so that the feed wires 2, 2' are moved toward the other side. It shall be made to protrude slightly more than '.

The instrument body 1 also has an insertion hole 1b for an external input power line 13, 13' at an appropriate location at the bottom of the groove 1a, and an opening IC having a width approximately equal to the distance between both ends 7a of the insulator 7. will be established.

Reference numeral 3 denotes a mounting bracket for the main body 1 of the instrument, in which a screw hole 3a for a stepped screw 5 to be attached to the ceiling 8 is provided in the center of the flat plate, and both ends thereof are appropriately fitted so that they can be locked to the sides of the groove 1a of the main body 1. Bend it so that it has the same angle, if necessary, the same inclination as the inner surface of the groove 1a.

Reference numeral 4 denotes a hook-type quick-connection terminal block that is attached to the opening 1C of the device main body 1, and has a built-in connection mechanism that enables connection to a ballast (not shown).

This connection terminal block 4 is located in the opening 1C and is locked to both ends 7a of the insulator 7 by rotating 90 degrees, and has hook-shaped conductive claws 6.6' that connect with the feed wirings 2 and 2'. to protrude.

Reference numerals 9 and 9' designate internal wiring for connection to the quick connection mechanism built into the quick connection terminal block 4, 10 a lamp socket, 11 a fluorescent lamp, and 12 a reflector plate.

Since the present invention is constructed as described above, when installing the appliance main body 1, the mounting bracket 3 is first screwed onto the ceiling 8 with the shoulder screws 5.

Next, the appliance body 1 can be easily attached to the ceiling by sliding the appliance body 1 onto the ceiling surface and fitting the groove 1a into the mounting fitting 3 and locking it.

If the appliance main body 1 is lightweight, the appliance main body 1 can be stably attached to the ceiling 8 even with one mounting bracket 3 by positioning the mounting bracket 3 approximately at the center of the appliance body 1.

In this case, since the mounting bracket 3 is rotatably screwed in by the stepped screw 5, the instrument main body 1 can be rotated through 360 degrees around the stepped screw 5, and arbitrary illumination can be obtained.

Additionally, if the appliance body 1 is heavy, the appliance body 1 can be easily attached to the ceiling 8 as described above by attaching a plurality of mounting brackets 3 at appropriate intervals within the length of the appliance body 1 using stepped screws 5. In addition to being able to sufficiently withstand the weight of the instrument body 1.

If multiple mounting brackets 3 are used, it is difficult to install them in a straight line on the ceiling surface, but since they are screwed in place with stepped screws 5, if only the stepped screws 5 are arranged in a straight line,
The rotation can be freely adjusted, so there is no need for so-called centering, and therefore the instrument main body 1 can be installed smoothly.

On the other hand, to connect the device, connect the input power line 13, 13' to the connecting terminal block 4 through the insertion hole 1b of the device body 1, and make sure that the conductive claws 6, 6' are parallel to the longitudinal direction of the device body 1. Place the connecting terminal block 4 against the opening 1C of the main body of the device, rotate it 90 degrees to lock the conductive claws 6 and 6' to both ends 7a of the insulator 7, and connect it to the feed wiring 2, 2' with one touch. This has a large labor-saving effect.

That is, in this case, when the device main body 1 is used alone, electricity is supplied by simply connecting the input power line 13, 13' and the connecting terminal block 4, but the conductive claw 6 of the quick-connect terminal block 4 , 6', power is also supplied to the feed wiring 2.2' for the feed power when a plurality of instrument bodies 1 are connected.

FIG. 5 shows another embodiment of the present invention in which the instrument bodies are connected, and the feed wires 2.2 of the instrument body 1 are adjacent to the ends of the feed wires 2, 2' of one instrument body 1. Conductive springs 14, 14' are fixed to the end portions of the conductive springs 14 and 14'.

According to this embodiment, even if a plurality of instrument bodies 1 are connected, each instrument body 1 can be electrically connected by the feed wires 2, 2' through the conductive springs 14, 14' by sliding in the direction of the arrow. Therefore, it is sufficient to provide the human power supply wires 13, 13' in one appliance main body 1, and there is no need for the feed wiring to pass through the appliance main body, making wiring easy.

As mentioned above, in this invention, the mounting bracket is installed by fitting the groove formed on the back side of the device body, and the feed wiring is attached to connect to the device adjacent to the groove, so it is easy to install the device body and the feed wiring. It is possible to easily perform the above operations, and it is possible to shorten the time required for upward work when installing instruments, reduce worker fatigue, and improve work efficiency.
