Description

[Detailed description of the invention] This invention is a system ceiling structure in which the ceiling material is suspended by an inverted T-shaped ceiling hanging fixture, and a large number of fluorescent lights are arranged vertically between the ceiling materials. This invention relates to a ceiling lighting fixture that can be used for lighting purposes.

Figures 1a and 1b show the structure of a conventional ceiling lighting fixture, and as shown in the figure, the conventional ceiling lighting fixture includes a socket cover 25 on which the socket 4 of the fluorescent lamp 3 is attached; The equipment plate 1 to which the equipment 21 such as a fire detector is mounted is formed as a separate piece, which makes construction difficult.
There is a seam in the connecting part, creating a step or gap,
The drawback was that it had an unsightly appearance. In addition, there is a lot of air circulation between the ceiling and the living room through the space between the two, which has the disadvantage that dirt adheres to the area between the two, making it even more unsightly as it is used. Furthermore, since the main body of the device has many components, it is heavy and requires many assembly steps, resulting in high cost.

The present invention was devised to solve these problems of the conventional example, and integrates the socket cover and the equipment plate, which were conventionally configured as separate pieces, to facilitate construction and to make the socket cover and equipment plate easier to install. Eliminates the seam between the equipment plate and
It is an object of the present invention to provide a ceiling lighting fixture which prevents the occurrence of steps and gaps and also prevents dirt from adhering to joints.

The configuration of the present invention will be described below with reference to illustrated embodiments. In the present invention, as shown in FIGS. 2 and 3, sockets 4 for fluorescent lamps 3 are attached to both sides 2 of an equipment plate 1 having a substantially U-shaped cross section, and a plurality of fluorescent lamps 3 are connected to the They are arranged vertically on the ceiling surface 5 with equipment plates 1 interposed therebetween. A stabilizer 6 is built into the equipment plate 1 and covered with a stabilizer cover 7. In conventional ceiling lighting fixtures, the ballast box 8 is provided on the top surface of the lighting fixture body 9, and therefore the lighting fixture body 9 must have sufficient strength to support the weight of the ballast 6. be. Compared to this, the lighting equipment of the present invention has the ballast 6 built into the equipment plate 1, so it is only necessary to place the reflector 10 on the top surface of the equipment plate 1, and it is not particularly robust as in the conventional lighting equipment. There is no need to provide the lighting fixture body 9. Therefore, in the present invention, the reflecting plate 10 is merely positioned on the upper surface of the equipment plate 1, with its position regulated by the guide pin 11. Therefore, the reflector plate 10 can be easily removed by lifting it from below, and by removing the reflector plate 10, it can be used as an inspection hole in the ceiling. The ceiling material 12 is placed on a horizontal piece 14 of an inverted T-shaped ceiling hanger 13, and the end of the equipment plate 1 is placed on the other side of the horizontal piece 14. A fixing metal fitting 15 is provided on the ballast cover 7 of the equipment plate 1, and is brought into contact with the top of an inverted T-shaped hanging fitting 13. 6a and 6b show other examples of the fixing fitting 15, and in the case of the fixing fitting 15a shown in FIG.
The ceiling hanging fixture 13 and the equipment plate 1 are completely fixed by bending at the parts shown in FIG. be. The ceiling hanger 13 has a locking piece 19 for locking the electric wire.
is provided so that the electric wire 20 can be housed therein as shown in FIG. 6b. The equipment plate 1 has a third equipment 21, such as a fire detector, for example.
It can be installed as shown in the figure. Furthermore, an accessory 22 as shown in FIG. 5 can be attached between the two fluorescent lamps 3.

23 is a connector, which supplies power to the ballast 6. FIG. 7a shows an example of a method of supplying power to the fluorescent lamp 3. As shown in the figure, a ballast 6 for two lamps is used, and one fluorescent lamp 3a is connected to one wiring 24a. By turning on the fluorescent lamps 3b on the other side using the wiring 24b on the other side, it is possible to easily light only one row of the fluorescent lamps 3a, 3b on one side in a two-lamp lighting fixture. It is possible to save power. Figure b shows the conventional power supply method.
can only turn all lights on or all lights off,
Although it is not possible to turn on and off only one row of fluorescent lamps 3 on one side, wiring can be done somewhat easily. In both the power supply methods shown in Figures 7a and 7b, it is necessary to conduct crossover wiring between the sockets 4 attached to both ends of the fluorescent lamp 3, but in the power supply method shown in Figure 7c, such a wiring is required. The crossover wiring is omitted, and in such a case, it is necessary to use a special ballast 6a that can omit the crossover wiring.

The present invention is constructed as described above, and in a system ceiling configuration in which the ceiling material is suspended by an inverted T-shaped ceiling suspension fixture, the ceiling material is suspended on both sides of an equipment plate having a substantially U-shaped cross section. Since a socket for a light lamp is attached and a plurality of fluorescent lights are arranged vertically in a row on the ceiling surface through the equipment plate, the socket cover and the equipment plate are constructed as separate pieces. Compared to the conventional example, there is no seam on the bottom surface of the equipment plate, no steps or gaps on the ceiling surface that give an unsightly appearance, and no dirt gets stuck in between the gaps as a result of use. It has the advantage that it does not cause stains to become noticeable when exposed to heat, is easy to install because there are few component parts in the main body of the device, is light in weight, and requires fewer assembly steps and can reduce costs. . In addition, since the electrical parts for lighting such as the ballast are housed within the equipment plate, the weight of the ballast etc. is not placed on the lighting equipment body, and there is no need to make the lighting equipment body sturdy. Moreover, since electrical parts for lighting such as ballasts are housed within both ends of the equipment plate, space is taken up in the center of the equipment plate to install equipment such as fire detectors. Even though electrical parts for lighting such as ballasts are housed within the equipment plate, there is no problem in installing equipment to the equipment plate, and in this way, lighting Since the equipment can be attached to the center of the equipment plate without any interference from electrical parts, the height of the equipment does not increase. Furthermore, an equipment plate is placed between the ends of each reflector placed between the horizontal pieces of the ceiling hanger, and the end of the reflector is placed on the upper end of the side piece of the equipment plate. Since a guide pin is provided protruding from the upper end to regulate the position of the end of the reflector, the equipment plate is positioned at the length interval of the reflector by regulating the end of the reflector with the guide pin. The equipment plate that needs to be placed according to the length of the lamp can be attached to the correct position, and the reflector plate can be placed on the ceiling hanger and the side plate of the equipment plate. has been done,
By lifting and removing the reflector, it can be used as an inspection port on the ceiling.
