[Detailed description of the invention] This invention relates to the improvement of lighting fixtures that are directly attached to the interior walls and ceilings of various stores. It is designed to project clear straight line light in a colored state and in the overall radiation state, and to obtain a temporary lighting effect that is rich in interest and variation in interior decoration. be.

Hereinafter, the specific structure of the present invention will be described in detail based on the illustrated embodiment. In FIGS. 1 to 7 showing the assembled state of the lighting equipment, 10 is a hollow cylindrical equipment body with open front and rear ends. A plurality of (total four in the illustrated example) light-transmitting outer windows 11 are opened through the body surface in an overall radially symmetrical arrangement. Reference numeral 12 designates a pair of stopper protrusions that are located in the middle between adjacent outer windows 11 and integrally protrude inward from the barrel surface of the instrument body 10, and between each pair of opposing stopper protrusions, A guide groove 13 for receiving a blade plate of a partition frame, which will be described later, is defined.

In that case, the protruding line 12 and the concave line 13 are connected to the instrument body 10.
The length L1 of the ridge 12 is the length L2 of the instrument body 10.
As a result, the remaining front end of the instrument body 10 is provided with a female thread 14. Using the female screw 14, the rotary cap 15 is removably screwed and fastened, so that the front surface of the instrument body 10 is covered.

Reference numeral 16 denotes a partition frame within the device main body 10, which consists of a small cylindrical hollow support 17 and a plurality of blade plates 18 (four in total in the illustrated example) that extend integrally in a radially symmetrical direction. The plate 18 is the instrument body 1
By being slidably inserted into and engaged with the grooved line 13 of No. 0 from the direction of the cylinder core, it is installed in the instrument main body 10 in a non-rotatable manner. In other words, the interior of the instrument main body 10 is equally divided into a plurality of fan-shaped compartments S (four in total in the illustrated example) by the partition frame 16.

The blade plate 18 of the partition frame 16 is substantially equal to the length L1 of the above-mentioned protrusion 12, and the length L3 of the hollow support 17.
is slightly longer than this, and its front and rear ends protrude tall from both front and rear ends of the vane plate 18. Reference numeral 19 denotes a light-transmitting inner window which is opened through the body surface of the hollow support 17 while facing the intermediate position between the adjacent blade plates 18, and corresponds to the state in which it communicates directly with the outer window 11 in the instrument body 10. We are doing so.

Reference numeral 20 denotes a pair of front and rear holding plates for holding a color filter and a lens, which will be described later.They have an annular shape with the same outline as shown in FIGS. Above hollow support 1

Reference numeral 22 denotes a plurality of locking notches (a total of four in the illustrated example) which are opened in each holding plate 20 so as to face the small chamber S correctly. A lens 23 having a semi-cylindrical cross section and a flat color filter 24 as shown in FIGS. 10 and 11 are inserted and locked at a constant distance W so that they cannot be displaced. Therefore,
The outer window 11 of the instrument body 10 and the inner window 19 of the hollow support 17 are blocked by the lens 23 and filter 24.

In this case, the lens 23 is arranged in parallel on the outside of the filter 24 with the light incident side being a flat surface, and the color light beams passing through the lens 23 are converged by the outer arcuate surface, and the contour edges of the light beams are clearly defined. become Reference numeral 25 denotes a lens cover located outside the arcuate surface of the lens 23 and also inserted and locked into the locking notch 22 of the holding plate 20,
It has an arc-shaped cross section as shown in FIGS. 12 and 13, and an intermediate window 26 for transmitting light is opened in the center thereof.

The lens 23, filter 24, and lens cover 25 are all removable and replaceable,
By replacing the cover 27 with another completely blind cover 27 (see FIGS. 14 and 15) that does not have the intermediate window 26, and inserting and locking it into the holding plate 20 from the front and rear directions, its light-transmitting effect can be improved. It is also possible to selectively block it. Reference numeral 28 indicates a cord lead-out hole formed in each holding plate 20, and 29 indicates a bolt insertion hole of a mounting flange, which will also be described later, and is opened in the form of an arcuate long hole.

Reference numerals 30 and 31 denote a front cover plate and a rear cover plate which are joined to the retaining plate 20 from the front and back directions, and while the former has an annular shape with a center hole which will be described later, the latter has this shape. Both of the pair are attached and fixed to the holding plate 20 by a plurality of screws 32. Due to this fixation, the filter 24, the lens 23, and the lens cover 25 are, so to speak, clamped from the front and rear directions, and are kept in a state where they cannot be removed. 33 is a cushion seat inserted between the joint surfaces of the holding plate 20 and the cover plates 30 and 31;
To safely protect a lens 23 and a filter 24.
34 is a cord lead-out hole provided in each of the cover plates 30, 31, and 35 is a bolt insertion hole, both of which coincide with the code lead-out hole 28 and bolt insertion hole 29 of the holding plate 20.

Reference numeral 36 denotes a circular saucer-shaped concave stepped surface processed into the center of each lid plate 30, 31, and when the lid plate 30, 31 is joined and fixed to the holding plate 20 as described above, the partition frame 16 is inserted into the concave stepped surface 36. Both front and rear ends of the hollow support 17 are received. At the center of the recessed stepped surface 36 of the cover plate 30 is a socket 3 for a lamp 37.
A center hole 39 is opened to allow the hole 8 to escape.

Reference numeral 40 denotes a spring receiving plate which is integrally connected to the concave step surface 36 of the front cover plate 30 from the front with screws 41, and 42 is a socket receiving stand fixedly installed for the socket 38, and a plurality of sockets are connected to the spring receiving plate 40. It is attached with a lamp adjustment screw 43. Reference numeral 44 denotes a compression coil spring which is wound around each lamp adjusting screw 43 and is interposed between the front and rear facing sides of the socket holder 42 and the spring receiving plate 40, and acts to absorb the shock of the lamp 37.

The lamp 37 that is installed toward the rear from the socket 38 faces the inside of the hollow support 17 of the partition frame 16, so that the light emitted from the lamp 37 is directed toward the hollow support 17.
The light passes through the inner window 19 of the lens, the color filter 24 and the lens 23, and is transmitted through the intermediate window 26 of the lens cover 25 and the outer window 11 of the instrument body 10 in an overall radially symmetrical direction. In that case, the positioning of the lamp 37 and the inner window 19 can be adjusted by moving the screw 43 around which the spring 44 is wound forward and backward in the front and rear directions.

Reference numeral 45 is a mounting flange for fixing the lighting device to a ceiling or wall, and is fitted into the rear surface of the device body 10 so that the rear cover plate 31 is overlapped from the rear. A plurality of long stud bolts 46 that stand up integrally pass through the bolt insertion holes 29 and 35 of the above-described retaining plate 20 and cover plates 30 and 31, and are screwed and fastened from their front ends by nuts 47. It is assembled and fixed.

According to the above structure, for example, the entire body except for the front cover plate 30 and the holding plate 20 is first assembled as described above, and the instrument main body 10 is fitted from the front so as to cover it. Partition frame 16 for board 20

Finally, by screwing and fastening the rotating cap 15 to the front surface of the device main body 10, the lighting device can be completed.

The assembly order is not necessarily limited to the above, but in any case, the guide groove 13 of the instrument body 10
The blade plate 18 of the partition frame 16 that is inserted and screwed together is fixed and integrated with both retaining plates 20 that are in contact with the protrusions 12, so there is no fear of the partition frame 16 slipping out from the instrument body 10. , will be kept in its restrained fixed state.

When the mounting flange 45 of the lighting fixture is directly fixed to, for example, a ceiling surface C in a room and the lamp 37 is turned on and used, the light emitted from the lamp 37 is filtered through the color filter 24 as shown in FIG. The colored light is converged into a straight line with clear contour edges by the lens 23, and flows out all at once in a radially symmetrical state from the outer window 11 of the appliance body 10, and reaches the ceiling surface C and wall surface. The projected light can provide an elegant decorative effect to the interior of the room.

In that case, the socket pedestal 42 of the lamp 37 is supported by an adjustment screw 43 wrapped around a compression coil spring 44 so as to be able to move forward and backward toward the front cover plate 30, and by removing the rotation cap 15, Since the front side of the device main body 10 is designed to be fully opened, the lamp 37 and the inner window 1 can be opened by moving the adjusting screw 43 forward and backward.
9 can be adjusted correctly, and it is possible to effectively prevent the light distribution from the outer window 11 from changing even due to a slight dimensional error.

In addition, the mounting flange 45 and the rotating cap 15, which are directly attached to the indoor wall or ceiling surface C, are located in opposite positions facing each other, so that even when the lighting fixture is directly attached, it cannot be seen from the front of the fixture body 10. By removing the rotary cap 15 and the socket holder 42 from the front cover plate 30, the lamp 37 can be easily replaced without any trouble.

As described above, the direct-mounted lighting device according to the present invention has a plurality of translucent external windows 11 on the body surface due to its structure.
A hollow cylindrical instrument body 10 in which guide grooves 13 for receiving slats located at mutually intermediate portions of adjacent outer windows 11 are arranged in a radially symmetrical distribution pattern as a whole; In order to equally divide the inside of 10 into a plurality of fan-shaped small rooms S, a cylindrical hollow column 17 is provided with a plurality of light-transmitting inner windows 19 opened in the body surface and corresponding to the state of direct communication with the outer window 11. , consisting of a plurality of vanes 18 integrally extending from the body surface of the hollow support 17 in a radially symmetrical distribution type, and
A partition frame 16 whose blade plates 18 are all inserted into and engaged with the guide grooves 13 of the instrument main body 10, and a locking notch 22 facing each small chamber S of the partition frame 16.
A pair of front and rear annular retaining plates 20, which are identical to each other, are assembled and fixed to the blade plate 18 of the partition frame 16 from the front and back directions via screws 21, respectively; Outside window 1 in each small room S
1 and the inner window 19, a plurality of flat color filters 24 are inserted and locked in the respective locking notches 22 in an extended state between the front and rear of both the holding plates 20 so as to be freely inserted and removed; They can be inserted and removed freely into the locking notches 22 between the front and rear of both retaining plates 20 so that they are parallel to each other at a position outside of the color filter 24 and their arcuate surfaces face the outer window 11. A plurality of semi-cylindrical lenses 23 that are inserted and locked, and a circle that is assembled and fixed to both retaining plates 20 from the front and back directions via screws 32, respectively, in order to hold the lenses 23 and the color filter 24 in a state where they will not come off. Ring-shaped front cover plate 30 and disk-shaped rear cover plate 3
1, a disk-shaped mounting flange 45 fitted to the rear surface of the device main body 10 in order to close the rear side cover plate 31 from the rear, and a disk-shaped mounting flange 45 that penetrates both the retaining plates 20 and both cover plates 30, 31. , a plurality of stud bolts 46 are integrally planted forward from the mounting flange 45, and each nut 47 is screwed into the tip end thereof from the front; A socket pedestal 42 is assembled and supported by a plurality of lamp adjustment screws 43 so that it can be moved back and forth in the front and rear directions.

When the mounting flange 45 of the appliance main body 10 is directly attached to a wall or ceiling C in a room, the light emitted from the lamp 37 is converted into colored light by the filter 24, and the contour edge is converted by the lens 23. It is set so that it can flow out in a radially symmetrical direction from the outside window 11 of the appliance body 10 while converging in a clear straight line, so it can be directly directed to a show window or an indoor wall or ceiling C of various stores. By using the color filter 24, a decorative accent consisting of sharp colored light rays can be given to the room, and the color of the color filter 24 can be varied from one another. This has the advantage that interesting and novel lighting effects can be achieved.

In other words, in the case of the present invention, the hollow support 1 of the partition frame 16
A light source lamp 37 is placed inside the light source lamp 37, and a flat color filter 24 and a semicylindrical lens 23 with an arcuate surface facing outward are arranged in parallel in a small chamber S partitioned by a vane plate 18 around the light source lamp 37. Since each lamp 37 is housed, the light emitted from the lamp 37 can be colored and converged in a straight line, and can be projected sharply as far as possible.

In this regard, in the invention of Utility Model Publication No. 30-3184, even though the cylinders 2 and 4 enclosing the temporary lamps have lattice holes, they are not equipped with a lens that converges the light as in the present invention. Therefore, the light is not projected clearly in a straight line. It is simply a desk lamp that emits colored light.

In addition, in the invention of JP-A-56-63702, the light source is a round fluorescent tube 1, and the lens body 4 that encloses it is also installed with its convex curved surface facing inward. It should be said that the light emitted from 1 is still diffused and is not converged as colored light rays heading in the radial direction as in the present invention.
The decorative effect of the above lighting of the present invention cannot be obtained.

Furthermore, the lighting equipment of the present invention can be used on indoor walls and ceilings.
It is a direct attachment type to the color filter 24.
and the lens 23 into the locking notches 22 of both retaining plates 20,
Since it is inserted and locked in such a way that it can be inserted and removed, the color applied to the light can be changed, especially by replacing the color filter 24. In other words, light rays of different colors for each chamber S,
It can flow out through the outer window 11 of the instrument body 10.

In addition, where the mounting flange 45 that covers the rear surface of the instrument body 10 is used by directly attaching it to the indoor wall or ceiling surface C, the rotating cap 15 that covers the opposite front surface is attached to the instrument body 10. Since it is removably screwed together, even if the lighting fixture itself is directly attached to the ceiling surface C, etc., the cap 1
By removing the lamp 5, the lamp 37 can be easily replaced from the front without any trouble.

In the above-mentioned invention of JP-A-56-63702, the round fluorescent tube 1 is completely covered in a double manner by the round ring-shaped lens body 4 and the color toning filter 5, so that the lens The fluorescent tube 1 cannot be replaced unless the body 4 and filter 5 are also removed, which is extremely complicated and inconvenient.

Further, in the case of the present invention, the socket holder 42 is assembled and supported from the front to the center of the front cover plate 30 via a plurality of lamp adjustment screws 43, and a compression coil spring 44 is wound around the screws 43. Because of this, vibrations and shocks applied to the lamp 37 can be naturally and effectively absorbed.
By moving the lamp 3 forward and backward, the lamp 37 can always be correctly aligned with the inner window 19 of the partition frame 16, and the light emitted from the lamp 37 flows out in the radially symmetrical direction of the device body 10. This has the effect of constantly correcting the light distribution evenly and uniformly. Such effects cannot be achieved using the above-mentioned known inventions and ideas.
