Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a ceiling-hanging decorative lighting fixture, and is particularly suitable for improving the decorativeness of lighting in halls and stores where a large number of people gather. It is something.

<Conventional technology and its problems to be solved> This type of decorative lighting equipment uses a plurality of arcuate fluorescent lights arranged in a continuous circle around a cylindrical equipment body that is directly attached to the ceiling. It is known to have an annular shape and to be fixedly supported in a stacked state in several stages, but this still lacks a three-dimensional effect with a rich variety of interest and appeal to the public, especially when the ceiling surface is extremely high. There are also problems such as a decrease in illumination intensity and an increase in the size and weight of the entire device.

<Means for Solving the Problems> The present invention is intended to improve the above-mentioned problems, and for this purpose, as a ceiling-hanging decorative lighting fixture, a hanging pipe for wiring from the ceiling surface and its hanging pipe are used. A spherical device body attached to the hanging tube so as to be centered approximately at the lower end of the hanging tube, and a number of groups of light transmission holes opened in a scattered distribution on the spherical surface of the device body. , A white or silver reflective film painted on the inside of the spherical surface of the device body, and multiple light bulbs installed in a radially symmetrical arrangement in plan view at the lower end of the hanging tube introduced into the device body. a plurality of wires extending from the spherical surface of the device body in a radially symmetrical arrangement with respect to its center, parallel to the diameter line of the device body when viewed from the side, and inclined by a certain intersection angle with the horizontal plane. A plurality of circular arc-shaped sockets are connected between adjacent fluorescent lamp sockets supported by the protruding tips of each of the socket support tubes in a ring shape that surrounds the main body of the device as a whole. It consists of a fluorescent lamp, and the light from the light bulb attached to the above-mentioned light bulb socket is transmitted through the light transmission hole of the device body as white or silver reflected light by the reflective film of the device body, as if it were a shining star. The main feature is that it is set to

<Function> The lighting equipment of the present invention as described above is used in places where many people gather, such as halls and various stores, where it is hung from the ceiling. This will create an impressive lighting effect.

In other words, the light from the light bulb is reflected by the reflective film inside the spherical device body as white light or silver light, and at the same time, it is transmitted to the outside like a shining star through the number of light transmission holes that open on the spherical surface. The fluorescent lamps that surround the main body of the device emit various colored lights in a band that is tilted at a certain angle with the horizontal plane, so the above-mentioned halls and stores will be temporarily renovated. In addition to providing a decorative effect through the lighting, it also effectively increases the appeal of attracting a large number of people.

<Example> Hereinafter, the specific configuration of the present invention will be described in detail based on the illustrated example. In Figures 1 to 10 showing the decorative lighting equipment, 11 is a hanging pipe from the ceiling surface C. A horizontal collar plate 12 integrally protrudes from the upper end of the collar plate, and a plurality of stud bolts 13
It is fixed to a stud 15 for attachment to the ceiling surface C via a cap nut 14. Reference numeral 16 designates a wiring hole for connection to a power source opened in the center of the stud 15, and reference numeral 17 designates a flange that covers the stud 15.

M is a lighting fixture body, which is assembled into a spherical shape as a whole from a pair of a relatively large upper hemisphere 18 and a small lower hemisphere 19, and the center O of the fixture body M is located at the hanging pipe 11. The upper end of the upper hemisphere 18 is fitted and integrated into the suspension tube 11 in a swinging and stable state so as to substantially correspond to the lower end. In other words, the lower end of the hanging pipe 11 is introduced to the center O of the spherical device main body M, and the wiring box 20 is fitted into the lower end in a communicating state, and is connected by a plurality of bolts 21. It is fixedly integrated with the hanging pipe 11.

Reference numeral 22 designates a pair of light bulb sockets which extend horizontally from the wiring box 20 in opposite directions, and a light bulb 23 is attached to each socket. A mercury lamp is most suitable as the light bulb 23, but the number may be increased to two or more arranged in a straight line as shown in the figure, as long as they are arranged radially symmetrically in plan view. According to this, the suspended state of the instrument main body M is stabilized, and moreover, it is possible to emit light evenly from the entire spherical surface.

P-P indicates the parting line between the upper hemisphere 18 and the lower hemisphere 19 in the instrument body M, which is the diameter of the instrument body M when viewed from the side as shown in Figures 1 and 5. Although it is parallel to the line D-D, it is inclined in particular by a constant crossing angle (θ) of preferably about 30 degrees with respect to the horizontal plane X-X. Furthermore, as described above that the sizes of the hemispheres 18 and 19 vary relative to each other, the parting line P-P is offset to a lower position than the center O of the instrument body M. W indicates the distance between the parting line P--P and the diameter line D--D, which are parallel to each other.

The lower hemisphere 19 is assembled to the upper hemisphere 18 which is fixedly installed on the hanging pipe 11 so that it can be opened and closed.

That is, 24 is a slanted opening flange that integrally projects from the spherical surface of the upper hemisphere 18 in a vertical L-shape so as to form a step, and has a wide width extending along the diameter line D-D of the instrument body M. We are facing a state of confusion. Reference numeral 25 denotes a wiring box which is fixedly installed inside the opening flange 24 with a backing attached, and maintains communication between a socket support tube for a fluorescent lamp, which will be described later, and the above-mentioned hanging tube 11. This prevents the outer cord from hanging down and being exposed into the hollow interior of the device body M.

On the other hand, the inclined opening flange 26 of the lower hemisphere 19
is L-shaped in cross section facing the opening flange 24 of the upper hemisphere 18, and is integrally formed from the spherical surface of the instrument body M.
It is located below the diameter line DD and extends in the form of a narrow band.

That is, while the opening flange 24 of the upper hemisphere 18 is formed extremely deep, the lower hemisphere 1
As a result of the opening flange 26 of No. 9 being formed extremely shallowly, the above-mentioned parting line P-P faces a lower position than the center O of the instrument main body M.

A is a hinge disposed on the parting line P-P between the upper hemisphere 18 and the lower hemisphere 19, and as is clear from FIG. Opening flange 24 at 18
The other wing piece 28 is attached and fixed to the opening flange 26 of the lower hemisphere 19, and the coupling pin 29 is used as a pivot point as shown in FIG. , lower hemisphere 1
9 is open so to speak, hanging down.

B is a locking fitting located on the parting line P-P and facing the hinge A in plan view, and as is clear from FIG. 10, the hook piece 30 is on the lower side. hemisphere 1
A rotary operating body 31 that is detachably engaged with the opening flange 26 of the upper hemisphere 18 is attached and integrated with the opening flange 26 of the upper hemisphere 18, respectively. In this regard, in the illustrated example, two locking fittings B are installed in parallel at regular intervals, but the number can be increased or decreased.

In that case, as is clear from FIG. 5, in relation to the inclined state of the parting line P-P, the hinge A is installed on the upper end side, so the lower hemisphere 19 is on the upper side. This acts to open the hemisphere 18 so that it hangs down from the upper end of the parting line P-P.
The opening rotation angle will not become too large or the opening will not hang down for a long time. As a result, various tasks such as replacing the light bulb 23 and maintaining the wiring can be performed as safely as possible.

32 is the number of groups of circular light transmitting holes that are opened on the entire spherical surface of the instrument body M excluding the two inclined opening flanges 24 and 26 of the upper hemisphere 18 and the lower hemisphere 19, and are dotted at regular intervals. It is arranged as a distribution state. Similarly, 33 is a white or silver reflective film coated inside the entire spherical surface in a so-called backing state, and when the light bulb 23 is turned on inside the appliance body M, the light is diffusely reflected by the reflective film 33. Therefore, when observing the device body M from the outside, the light from the bulb 23 is transmitted through the light transmission hole 32 as white light or silver light, giving an impression of the illumination effect of a shining star.

Reference numeral 34 denotes a plurality of wiring socket support tubes to which the fluorescent lamps 35 are to be attached, which are located centrally from the inclined opening flange 24 of the upper hemisphere 18 in the main body M of the device on the above-mentioned diameter line D-D. It is drawn out parallel to the diameter line D-D and the parting line P-P. The plurality of them as a whole are arranged in a radially symmetrical manner with respect to the center O of the instrument body M as shown in FIG. Reference numeral 36 denotes a fluorescent lamp socket fixedly supported at the protruding end of each socket support tube 34, and the arc-shaped fluorescent lamps 35 are connected so as to be interposed between adjacent sockets. 37 is a cover of the socket 36.

Therefore, the plurality of fluorescent lamps 35 as a whole surround the inclined equatorial plane of the spherical instrument main body M. Each socket support tube 3
The protruding base end of No. 4 is attached and fixed to the opening flange 24 of the upper hemisphere 18 in communication with the attached wiring box 25. The cord to the fluorescent lamp 35 is connected from the hanging tube 11 to the wiring box 25.
The fluorescent lamp socket 36 is connected to the fluorescent lamp socket 36 through the hollow interior of the socket support tube 34.

38 is the opening flange 2 of the upper hemisphere 18 between adjacent socket support tubes 34.
The fluorescent lamp support stays are arranged in a radially symmetrical arrangement from 4, and stably support the intermediate portions of the arc-shaped fluorescent lamps 35. 39 is each support stay 3
The elastic claw attached to the protruding tip of No. 8 is shown.

In that case, the socket support tube 34 for the fluorescent lamp is
As is clear from FIGS. 1 and 5, the support stays 38 are formed into a plurality of lengths each extending from the main body M of the instrument, and the lengths of the support stays 38 are different from each other. As a result, the fluorescent light supported by these stays The diameter of the ring of the lamp 35 as a whole is also varied in size. The lighting equipment as a whole is shaped to give the impression of Saturn, which is full of interesting and varied interests. Note that it is desirable that the plurality of fluorescent lamps 35 emit light of different colors.

<Effects of the invention> As described above, in the present invention, due to the structure of the lighting fixture, the hanging pipe 11 for wiring from the ceiling surface C and the lower end of the hanging pipe 11 are set approximately at the center O. A spherical instrument body M attached to the hanging tube 11, the number of groups of light transmission holes 32 opened in a scattered distribution on the spherical surface of the instrument body M, and the number of light transmitting holes 32 opened in a scattered manner inside the spherical surface of the instrument body M. a painted white or silver reflective film 33; a plurality of light bulb sockets 22 installed in a radially symmetrical arrangement in plan view at the lower end of the hanging tube 11 introduced into the appliance body M; Parallel to the diameter line D-D of the instrument body M when viewed from the side, and at a constant intersecting angle (θ) with the horizontal plane X-X
A plurality of wiring socket support tubes 34 are projected from the spherical surface of the device main body M in a radially symmetrical arrangement with respect to the center O thereof, and a firefly supported by the projected tip of each of the socket support tubes 34 is tilted by the same amount. It consists of a plurality of arc-shaped fluorescent lamps 35 connected between adjacent lamp sockets 36 in a ring shape that surrounds the main body M of the appliance as a whole, and includes a light bulb 23 attached to the above-mentioned light bulb socket 22. The light of
2, the light reflected from the light bulb 23 is set to pass through the light bulb 23 as if it were a shining star, so the reflected light from the light bulb 23 passes through the scattered light transmission holes 32, where it can be seen as shining white light or silver light at any position on the device body M. It can be seen reliably even from any direction, and together with the light emitted from the fluorescent lamps 35 surrounding the spherical surface of the instrument body M, it is possible to give an impression of a significantly new lighting effect of Saturn as a whole. It can be said that it is extremely useful for hanging decorations in halls where people gather, various stores, etc.

Sometimes, as is clear from the illustrated embodiment, the instrument body M
is divided into a pair of a relatively large upper hemisphere 18 and a smaller lower hemisphere 19, and the parting line P-P is inclined by a certain intersecting angle (θ) with the horizontal plane X-X. , if the main body M of the instrument is surrounded by a fluorescent lamp 35 in a generally annular state parallel to this, the fluorescent lamp 35
If it is supported by socket support tubes 34 of different lengths extending from the device main body M, and the diameter of the annular shape is changed in size, the shape that should give an impression of Saturn will be even more interesting. can be given.

In that case, the socket support tube 34 of the fluorescent lamp 35 is integrally extended from the inclined opening flange 24 of the upper hemisphere 18, and the large upper hemisphere 18 is fitted into the hanging tube 11 from the ceiling surface C. If it is attached and fixed, the overall hanging condition will be extremely stable. In addition, arranging a large number of light bulbs 23 in a radially symmetrical manner in a plan view by the sockets 22 also works effectively for this purpose.

Also, at the parting line PP inclined under the above angle (θ), the small lower hemisphere 1
9 is pivotally connected to the upper hemisphere 18 so that it can be opened and closed, it is possible to replace the light bulb inside the device body M, etc.
Various tasks such as wiring maintenance can be performed without any problems. In particular, this result shows that, as in the illustrated embodiment, the hinge A is moved toward the upper end side of the parting line P-P.
This can be achieved even more rationally by installing a .

Furthermore, the inclined opening flange 24 of the upper hemisphere 18
If the wiring box 25 is installed with a backing attached from the inside, and thereby the socket support tube 34 of the fluorescent lamp 35 and the hanging tube 11 from the ceiling surface C are communicated, the fluorescent lamp Wiring to the light bulb socket 36 can also be done extremely smoothly and properly without the cord hanging down into the hollow interior of the appliance body M.
It also does not block reflected light from.
