DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a lighting device most suitable for use in a gymnasium or a hall.

[Conventional technology and its problems]

2. Description of the Related Art In recent years, various measures have been applied to gymnasiums, halls, and the like so that so-called multipurpose use is possible.

For example, with respect to a roof, a lighting device may be provided so that the amount of light can be changed.

Originally, for daylighting from the roof, the whole roof should have a transparent structure using glass etc., but if the whole roof is a fixed type transparent structure, it is inconvenient when light shielding is required. When unnecessary, a light-shielding device that performs a light-shielding function when necessary is provided in some cases near the roof having the transparent structure.

As the lighting device in this case, for example, a lighting device that is formed in a blind structure having a large number of blades and that adjusts the amount of light by changing the inclination angle of each blade. is there.

Therefore, according to the lighting device having the blind structure, a desired amount of light can be secured only by changing the inclination angle of each blade, but on the other hand, a large number of the blades are arranged overhead, so-called unsightly. There is an inconvenience.

Further, when ceiling suspended objects such as lighting fixtures and sound equipment are arranged near the above-mentioned lighting device having a blind structure, and when these ceiling suspended objects are constructed to be movable, There is a drawback that it is liable to cause some inconvenience, for example, it is necessary to take appropriate care so that the suspended ceiling does not interfere with the blades.

The present invention has been made in view of the above-mentioned circumstances, and the object thereof is not only to enable necessary lighting, but also to provide a gym or a gymnasium by not hindering the arrangement of suspended ceilings and the like. An object of the present invention is to provide a lighting device optimal for use in a hall or the like.

[Means for solving the problem]

In order to achieve the above object, a lighting device according to the present invention has a structure in which a plurality of lighting devices each having a light-shielding plate for blocking an opening exposed to the indoor side are arranged, and the plurality of lighting devices are arranged. A light-shielding plate in any of the light-collecting devices is opened and closed so that a desired light-collecting amount is secured, and the light-collecting device has a large number of light-shielding plates that can swing, The plurality of light-shielding plates are disposed in sliding contact with a rotating plate formed to rotate around the opening while disposing the opening at the center thereof, and the plurality of light-shielding plates are arranged when the rotating plate rotates. A light shielding plate is formed so as to open and close the opening.

More specifically, the light-shielding plate has one end pivotally supported in the outer peripheral direction of the opening plate, and a pin is implanted on a surface adjacent to the rotating body. It is assumed that a guide groove for guiding the pin is formed on a surface adjacent to the light shielding plate, and the pin is moved in the guide groove when the rotating plate rotates, so that the light shielding plate swings. It is formed as possible.

[Action]

Therefore, a desired amount of light can be obtained with an arbitrary number of the daylighters among a large number of arranged daylighters, and by selecting a position of an operating daylighter, the daylighting mode is changed to an electronic bulletin board. It is possible to enjoy the visual change.

In the above case, the amount of light passing through the opening can be adjusted by changing and adjusting the swing amount of the light shielding plate with respect to the rotating plate.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

As shown in FIG. 1, the light-shielding device according to the present invention is provided with a so-called ceiling at a number of openings h formed in the ceiling skeleton C when the roof R of the building A is formed in a glass-enclosed form. It has a large number of daylighting devices I arranged to face each other from the back side.

By the way, as shown in FIG. 2, for example, as shown in FIG. 2, it is assumed that a total of 25 openings h are arranged vertically and horizontally on a ceiling surface c partitioned so that one side is a rectangle of an appropriate length. I have.

Therefore, in the illustrated example, since the daylighting devices I are respectively installed adjacent to the respective openings h, the above-mentioned divided ceiling surface c has:
25 lighting devices I will be provided.

In addition, the above-mentioned partitioned ceiling surface c may be used only in a single use mode, and as shown by an imaginary diagram in the figure, a plurality of four-sided In other words, a wide ceiling may be formed.

In addition, the daylighting machine I is described as being disposed on the so-called underside of the ceiling in the ceiling skeleton C. However, it is needless to say that the daylighting machine I may be disposed on the side of the ceiling surface c instead.

The daylighting machine I includes a rotating plate 10 and a light shielding plate 20, as shown in FIGS.

The rotating plate 10 faces the opening h at the center thereof, and
It is formed in a donut shape having a through hole 10a to be aimed, and is formed so as to be selectively rotated clockwise and counterclockwise around the through hole 10a.

The method of rotating the rotary plate 10 is essentially arbitrary, but in this embodiment, the rotary unit 10 is driven to rotate.

That is, it is assumed that a rack tooth 10b is formed on a part of the outer circumference of the rotating plate 10 and a pinion tooth 11a is formed on an outer circumference of the driving unit 11, and the pinion tooth 11a is formed on the rack tooth 10b. It is supposed to mesh with.

Therefore, in the illustrated example, the rotation plate 10 is rotated clockwise by driving the drive unit 11 to rotate counterclockwise.

In this embodiment, the rotating plate 10 can be rotated around the through hole 10a by a plurality of guides 1.

That is, the guide 12 also serves as a support portion provided to pivotally support a light-shielding plate 20, which will be described later,
A plurality of the rotating plates 10 are provided outside the outer periphery at equal intervals on the outer periphery.

Therefore, the rotating plate 10 is fixed to the so-called inside of the guide 12 when the driving unit 11 is driven, and is further rotated around the through hole 10a.

By the way, the rotating plate 10 has a guide groove 10c on its upper surface.
Having.

The guide groove 10c is formed to swing a light-shielding plate 20, which will be described later, when the rotary plate 10 rotates, and for the purpose of achieving the purpose, a tangent to a circumference forming the through hole 10a. It is arranged along the direction.

That is, the guide groove 10c has one end side facing the inner peripheral side of the rotating plate 10, while the other end side faces the outer peripheral side of the rotating plate 10, and its axial direction is the radial direction of the rotating plate 10. Are formed so as to be eccentric at an appropriate inclination angle.

The guide grooves 10c are formed on the upper surface of the rotary plate 10 in a number corresponding to the number of the guides 12 provided.

The light-shielding plate 20 has its base end pivotally supported by a support shaft 21, and has a pin 22 implanted on its back surface, that is, a surface adjacent to the upper surface of the rotating plate 10.

The light-shielding plate 20 is pivotally supported by a support shaft 21 and is swingable. When the light-shielding plate 20 swings, the through-hole 10a of the rotary plate 10 is so-called opened and closed.

That is, the light-shielding plates 20 are provided in plural numbers so as to correspond to the number of the guides 12, and are arranged so that the leading ends thereof are in a so-called overlapping relationship (FIGS. 6 to 6). (See FIG. 9).

The light-shielding plate 20 may be originally formed in an arbitrary shape and does not require any special limitation. However, in this embodiment, the following considerations are made.

That is, the light-shielding plate 20 has one side cut out from the overall shape of a substantially rhombus in an arc shape having a curvature corresponding to the circumference forming the through-hole 10a, and the other side and the tip side when the rocking is performed. A notch is formed so as not to contact the guide 12.

Thus, when the light shielding plate 20 swings around the support shaft 21, the through hole 10a can be in a so-called fully open state, and each light shielding plate It is possible to prevent inconvenience such that the ends of the 20 protrude greatly.

The pin 22 is guided in the guide groove 10c, and is formed so as to move from inside to outside in the guide groove 10c when the rotating plate 10 is rotated.

That is, as described above, the light-shielding plate 20 has its
It is pivoted at 21.

Therefore, when the rotating plate 10 is rotated, the guide groove 10c
The distance between the pin 22 and the support shaft 21 is unchanged while the distance between the pin 22 and the support shaft 21 is unchanged, so the pin 22 moves in the guide groove 10c when the light shielding plate 20 swings. Will do.

That is, the guide groove 10c and the pin 22 form a structure that converts the rotational motion of the rotary plate 10 into the swinging motion of the light shielding plate 20.

The operation of the daylighting device according to the present invention formed as described above will be described briefly.

First, when the daylighting machine I in the daylighting device performs a so-called light-shielding action, it assumes a fully closed state as shown in FIG.

Then, as shown in FIGS. 7 and 8, it is assumed that the so-called luminous energy is increased by gradually opening the aperture, and it becomes complete when the through hole 10a of the rotating plate 10 is fully opened as shown in FIG. It takes on a lighting state.

The swing angle of the light shielding plate 20 is determined by the selection of the driving amount of the driving unit 11, and the selection can be made by so-called remote control using a controller or the like.

By the way, in the operation of the daylighting device I, by operating only an arbitrary number of daylighting devices I out of a plurality (25 in the illustrated example), the ceiling surface c (FIGS. 1 and 2). (See the figure), for example, lighting in an arbitrary diagram such as an X shape, a cross shape, a square shape, or a rhombus shape becomes possible.

In the case where the ceiling surface c is formed in such a manner as to form a wide ceiling in such a manner that the ceiling surface c is continuously formed in a plurality of directions, a ceiling such as a so-called electric signboard can be used. By opening and closing the light shielding plate 20 in the above, it is also possible to display a design, a character, and the like on the ceiling.

In the above-described embodiment, the guide 12 for rotatably fixing the rotary plate 10 at a predetermined position is formed in a so-called pin form, but may be formed in a roller structure instead. .

Further, in the above-described embodiment, the guide 12 and the driving unit
Numerals 11 are provided on the ceiling skeleton C, respectively.
A power source (not shown) for rotating the drive unit 11 is installed in the ceiling frame C.

〔The invention's effect〕

As described above, according to the present invention, in a hall or a gymnasium, etc., not only can necessary lighting be provided, but even if a ceiling hanger is disposed on the ceiling frame, the operation of the lighting device itself can be performed. There is no anxiety that obstruction will be hindered, and by arranging a large number of lighting devices on the ceiling, lighting modes such as an electronic bulletin board will be possible and visually enjoyable. There is the advantage that the availability will be greatly increased.
