Description

[Detailed description of the invention] <Industrial field of application> The present invention is for system wiring that is connected to a connection bracket that is directly attached to the ceiling surface of a room as a whole radially symmetrical distributed installation state. Regarding multi-light lighting equipment.

<Conventional technology and its problems> Conventional multi-lamp lighting equipment for system wiring has an auxiliary discharge conductor attached to each fluorescent lamp due to its structure. When connecting multiple lamps in parallel to form a multi-lamp unit, the overall assembly work cannot be carried out with high efficiency, and the number of discharge auxiliary conductors also increases, resulting in increased cost and weight of the product - lighting equipment. As a result, this may lead to In addition, when installing multi-light lighting equipment on the indoor ceiling, multiple screws are used to connect and fix it to the connection bracket that serves as the pole to be distributed, which makes the work extremely complicated. There are also problems.

<Means for Solving the Problems> The present invention is intended to improve such problems, and for this purpose, several sets of sockets facing each other are fixedly held on a pair of front and rear end plates, and one set of sockets facing each other is In a multi-lamp lighting fixture in which fluorescent lamps are connected to different sockets in a generally parallel installation state, the front and rear pairs of the above end plates are connected by a hollow discharge auxiliary conductor located between adjacent fluorescent lamps. The conductor is designed to provide dual-purpose discharge support for adjacent fluorescent lamps and conduction of the wiring cord coming out from the socket, as well as a connecting bracket for distribution installation from each end plate to the ceiling surface of the room. It is characterized by an integrally protruding insertion piece that can be attached and detached from the holder.

<Example> Hereinafter, the specific configuration of the present invention will be described in detail based on the illustrated example. Figs. 1 to 7 show a two-lamp type lighting fixture for system wiring, and numeral 11 indicates a pair of front and rear ends. The plates are each formed from a metal plate and are bent into a substantially L-shape with opposing side sections.
12, 12 are horizontal screws 13,
A pair of left and right sockets are held in a fixed parallel state from the inside by 13, and a straight tube type fluorescent lamp 14 is inserted and connected horizontally between the front and rear of the opposing sockets 12, 12, respectively. There is.

In that case, glow starters 15 corresponding to the sockets 12, 12 are fixedly installed from the outside at both ends of the vertical side 11a of one end plate 11, as shown in the modified example of FIGS. 4 and 5. In any case, when a voltage is applied between the two electrodes of each of the fluorescent lamps 14, a discharge occurs and the fluorescent lamps 14 emit fluorescence. Note that the ballast is not shown.

Reference numeral 16 denotes a discharge auxiliary conductor that is interposed between the left and right sides of the adjacent fluorescent lamps 14 and connects and integrates the center portions of both end plates 11, and serves also for both of the adjacent fluorescent lamps 14. In order to function, it is adapted to assist the above-mentioned discharge action. Furthermore, the auxiliary conductor 16 is made of an extruded metal material such as aluminum and has a vertically elongated hollow rectangular cross section, so that the wiring cord 17 extending from both sockets 12, 12 can be electrically connected to the inside of the auxiliary conductor 16. There are some too.

At this time, since the auxiliary conductor 16 has a vertically elongated hollow rectangular cross section, it is possible to conduct the wiring cords 17 smoothly into the hollow interior without exposing the plurality of wiring cords 17. Even if it becomes considerably long, it is possible to effectively prevent bending and deformation such as hanging down from the center part. Even though lightweight aluminum extrusions are used, the rigidity of the installed state can be increased. However, as long as such purpose can be achieved, the auxiliary conductor 16 may be formed to have another hollow polygonal cross-section, or an elongated hollow elliptical cross-section along the vertical direction.

Reference numeral 18 designates an inverted L-shaped connecting piece with a side cross section that connects and integrates the open end of the discharge auxiliary conductor 16 and the center of the vertical side 11a of each end plate 11; The connecting piece 18 is spot-welded to the vertical side 11a of the end plate 11, while the horizontal side of the connecting piece 18 is inserted into and overlapped with the auxiliary conductor 16, and is fixed by vertical screws 19. It is clear from FIG. 3 that the open end of the auxiliary conductor 16 is not covered by the end plate 11 and is exposed as it is.

Further, the horizontal side portion 11b of each end plate 11 is formed to continuously project outward, and
It is bent into an almost U-shape when viewed from the front and rear directions. Reference numeral 20 denotes a synthetic resin insertion piece that is fixedly installed on the horizontal side 11b from above with a vertical screw 21, and is used by detachably inserting it into the connection bracket B as shown in Figs. 6 and 7. It's summery.

In other words, the connection bracket B is a hanger member that serves as a pole in order to distribute and install multiple of the above-mentioned two-lamp type lighting fixtures on the indoor ceiling surface C, and is directly attached and fixed to the ceiling surface C. . 2
2 is a direct mounting board for the connection bracket B, and 23 is a plurality of boards that also form the bracket B (a total of 4 in the figure).
7) from the direct mounting board 22.
It extends in a radially symmetrical manner as shown in the figure.

Each of the distribution leg cylinders 23 has a vertical cylinder part 23a,
It consists of a unit body including a horizontal cylindrical portion 23b which is freely inserted into and engaged with a plurality of slide guide pieces 24 fixed at the lower end position of the opening. 25 faces into the horizontal cylinder part 23b,
This is a receiving piece that is fixedly held at the lower end position of the opening of the vertical cylindrical portion 23a by a screw 26, and the insertion piece 20 of the end plate 11 is removably locked and fixed thereto as shown in FIG. It is becoming more and more common.

The horizontal cylinder part 23b of the distribution leg cylinder 23 is first covered with the end plate 11 of the lighting equipment, and by pushing and sliding it in the horizontal direction, the horizontal cylinder part 23b is placed in the slide guide of the vertical cylinder part 23a. To piece 24, also end plate 11
The plug-in pieces 20 can also be fixedly installed to the receiving pieces 25 of the vertical cylindrical part 23a in a locked state. This will ensure stable system wiring.

In this regard, in the figure, the insertion piece 20 is created as a separate object from the end plate 11, and its horizontal side 1
1b, and the end plate 11 is slid horizontally to engage with the receiving piece 25 on the connection bracket B side.
1b itself functions as the insertion piece 20, while the receiving piece 25 on the side of the connection bracket B is formed into a corresponding so-called dovetail shape and is bent from a leaf spring material, so that the insertion piece 20 can be moved in the vertical direction (upward direction). ) to the receiving piece 25 in a detachable manner.

Although the figure shows a two-lamp type lighting fixture, the present invention can also be applied to a multi-lamp type where three or more fluorescent lamps 14 are arranged in parallel, and in that case, the discharge auxiliary conductor 16 is The plurality of fluorescent lamps 14 are also interposed in parallel between adjacent fluorescent lamps 14.

<Effects of the invention> In any case, in the present invention, several sets of sockets 12, 12 facing each other are fixedly held on a pair of front and rear end plates 11, and the opposite one
In a multi-lamp type lighting fixture in which fluorescent lamps 14 are connected to each set of sockets 12 and 12 in an overall parallel installation state, the front and rear pair of the end plates 11 are particularly placed in an intervening position between adjacent fluorescent lamps 14. They are connected and integrated by a hollow discharge auxiliary conductor 16, and the conductor 16 is used to perform dual-purpose discharge assistance for the adjacent fluorescent lamps 14 and conduction of the wiring cord 17 coming out from the sockets 12, 12. , Since the removable insertion piece 20 for the connection bracket B for distribution installation on the indoor ceiling surface C is integrally extended from each end plate 11, it is possible to reliably solve the problems of the prior art mentioned at the beginning. be.

That is, a pair of front and rear end plates 11 are connected and integrated by a discharge auxiliary conductor 16 located between adjacent fluorescent lamps 14, and the conductor 16 performs a dual-purpose discharge auxiliary function for the adjacent fluorescent lamps 14. Fluorescent lamp 1 of 14
It does not require a large number of auxiliary conductors 16 corresponding to each book,
Not only can the cost and weight of the lighting equipment be reduced, but it can also be used as is by attaching it to the connection bracket B as a multi-light type.

Moreover, since the discharge auxiliary conductor 16 is hollow, the sockets 12 of the adjacent fluorescent lamps 14,
The wiring cord 17 coming out from the wiring cord 12 can also be made conductive to the inside of the auxiliary conductor 16 without being exposed unsightly, and it is also excellent for interior decoration as a system wiring. In that case, if the auxiliary conductor 16 is made into a polygonal or elliptical shape with an elongated cross section along the vertical direction, even if it is hollow and elongated, its bending deformation can be reasonably prevented, and it can be easily maintained in the installed state. Rigidity can also be improved.

Furthermore, since a removable insertion piece 20 for the connection bracket B for distribution installation on the indoor ceiling surface C is integrally protruded from each end plate 11, it can be used as a lighting fixture for system wiring to receive the connection bracket B. It is possible to connect the piece 25 easily and efficiently in a so-called one-touch manner without using any tools, and from that point of view it can be said to be of great practical benefit.
