Description

FIELD OF THE INVENTION The present invention relates to a luminaire suitable for use with a ring lamp.

2. Description of the Related Art A first conventional example of a lighting fixture will be described with reference to FIG. The lighting fixture 1 is mounted on the ceiling surface 2, and has a structure in which a reflector 4 and a globe 5 are sequentially connected to a chassis 3. Here, these parts 3 to 5 are formed in a circular shape that matches the ring-shaped lamp 6, and the ring-shaped lamp 6 is held by a lamp holder 7 attached to the reflection plate 4. Further, a ballast 8 and a lamp socket 9, both of which are electric parts, are attached to the lower surface of the chassis 3, and attachment fittings 10, 11 and the like are provided in the approximate center. And these mounting brackets 10 and 11 and wing nut 12
The reflection plate 4 and the globe 5 are attached to the chassis 3 with the decorative screws 13.

Next, a second conventional example of the lighting equipment will be described with reference to FIG. This luminaire 14 has the same structure as the luminaire 1 illustrated in FIG. 5, except that the chassis 15, the reflection plate 16 and the globe 17 are formed in a square shape.

In such a structure, the above-mentioned lighting fixtures 1 and 14 illuminate the room from the ceiling surface 2. The lighting fixtures 1 and 14 can be directly attached to a wall surface (not shown) or can be suspended from the ceiling surface 2 for use.

Problems to be Solved by the Invention The lighting fixtures 1 and 14 described above have substantially the same ring lamp 6 and various components 8 and 9 to be used, and are substantially the same. However, these luminaires 1 and 14 are formed in a circular shape or a quadrangular appearance shape in order to meet design demands. Therefore, the outer shapes of the chassis 3 and 15 are also formed into a circular shape and a quadrangular shape, respectively, and each requires a dedicated press die, jig, etc., and the lighting fixtures 1 and 14 are expensive. Especially, ballast 8, lamp socket 9 and mounting bracket 1
The chassis 3 and 15 to which 0, 11 and the like are attached have a large number of manufacturing steps, and it is not preferable to separately manufacture chassis 3 and 15 having different outer shapes.

Means for Solving the Problems The invention according to claim 1 forms an outer shape of a chassis in an octagonal shape, and makes a round or rectangular reflection plate circumscribe the outer peripheral portion of the chassis, and a lamp and a lamp are provided below the reflection plate. Round or square gloves were placed.

According to the second aspect of the invention, various electric components are attached along the sides of the chassis.

Function By forming the outer shape of the chassis into an octagonal shape and forming a reflective plate and gloves that circumscribe the outer periphery of this chassis, it is possible to use a common chassis to form lighting fixtures such as circles and squares. It is possible, and by mounting various electrical parts along the sides of the octagonal chassis, the electrical parts can be installed at large intervals at angles of 0 °, 45 °, 90 °, etc. , The mounting position can be made common even for electrical parts that differ in size depending on the wattage,
Wiring between the electric parts is easy and the assembling property of the lighting fixture can be improved.

Embodiment A first embodiment of the present invention will be described with reference to FIGS. 1 and 2. The same parts as those of the above-described conventional example are designated by the same names and reference numerals, and description thereof will be omitted. First, in this lighting fixture 18, the chassis 19 is formed in an octagonal shape.
As illustrated in the figure, the ballast 8, the lighting unit 20 for the emergency light, and the emergency light battery power supply 21 are provided along the sides of the chassis 19.
Etc. electrical parts are attached. A circular reflection plate 4 is attached to the outer peripheral portion of the chassis 19 so as to be circumscribed, and a circular globe 5 is attached thereon.

Next, a second embodiment of the present invention will be described with reference to FIGS. This lighting fixture 22 is the above-mentioned lighting fixture.
A rectangular reflector 16 on the outer periphery of the chassis 19 common to 18
Are attached so as to be circumscribed, and a square globe 17 is attached thereon.

Since the above-described lighting fixtures 18 and 22 have the same chassis 19 fixed to the ceiling surface 2, for example, even after the circular lighting fixtures 18 are installed, the reflectors 4 and 16 and the globes 5 and 17 are It is possible to easily change the lighting device 22 into a square shape by simply changing. Moreover, in these luminaires 18,22, various electric parts 8,20,21 are mounted along the sides of the octagonal chassis 19, so that these electric parts are 0 °, 45 °,
It is easy to install at 90 ° angle, and each part can be installed with a large space dispersed between them, so even electrical parts of different sizes depending on the wattage can be installed at the same mounting position, and the luminaires 18 and 22 can be easily assembled. Is good. That is, with the lighting fixtures 18 and 22 of the present invention, the chassis 19 can be commonly used even when producing lighting fixtures (not shown) having different wattages.

Further, in the above-described lighting fixtures 18, 22, the circular and quadrangular reflection plates 4, 16 are circumscribed on the octagonal chassis 19, but the present invention is not limited to this.
Various shapes of reflectors and gloves (both not shown) circumscribing the outer periphery of the chassis 19 can be used. Further, a glove (not shown) formed so as to circumscribe the outer periphery of the octagonal chassis 19 can be directly attached to the chassis 19.

EFFECTS OF THE INVENTION The present invention forms a chassis in an octagonal shape as described above, and forms a reflecting plate and a glove circumscribing the outer peripheral portion of the chassis, so that a common chassis is used to form a circular shape or a square shape. It is possible to form lighting fixtures, and even when various lighting fixtures are produced, the press mold of the chassis is common, and the setup process of the chassis can be reduced to increase the number of lots. It can be manufactured at low cost, and by mounting various electrical components along the sides of the octagonal chassis, the electrical components can be installed at 0 °, 45 °, 90 °.
Since it can be installed by being distributed at large intervals at angles such as °, it is possible to use common mounting positions even for electrical parts that differ in size depending on the wattage, and it is possible to improve the assembleability of lighting equipment. It is a thing.
