In other words, the instrument main body A together with its inner cylinder 20 is shaped into a hollow cylinder with a double structure. Reference numeral 22 denotes a pair of left and right lens holder support brackets that are welded from the inside to the body wall of the instrument body A at positions near the front and rear openings of the instrument body A, and plate pieces bent inward from these brackets. On the 23rd, the 7th
As is clear from FIGS. 9 to 9, screw holes 24 for receiving screws are formed through each of them.

25 is a spring receiving piece welded to the body wall of the hollow inner cylinder 20, and 26 is a pair of left and right leaf springs that make it possible to adjust the focal length of a convex lens, which will be described later.
It is curved into a substantially horizontal V-shape that widens toward the outside of the opening of the hollow inner cylinder 20, and is welded to the spring receiving piece 25 only at its central base end. Therefore, it acts elastically in an undulating manner with its central base end as a fixed fulcrum, and when a lens holder is fitted, which will be described later, it comes into contact with the opening edge of the holder and applies elastic back pressure in the extrusion direction. obtain. however,
It is also possible to use a compression coil spring or other spring material instead of the leaf spring 26 as long as it can perform this action.

Furthermore, C is a pair of lens holders that are fitted into the instrument body A so as to cover the front and rear openings of the instrument body A, and are made into a unit body that is separate and independent from the instrument body A in advance. As such, it is equipped with a filter plate 27 and a convex lens 28.

That is, the tenth to
In FIG. 13, 29 is a body frame portion of each lens holder C, and the hollow inner cylinder 20 is visible from the front and rear directions.
It has a similar shape that fits inside the. 30
A cover flange is integrally welded to cover one end of the opening of the body frame 29, and is made of a flat plate having a size and shape that match the front and rear openings of the instrument body A. Reference numeral 31 denotes a pair of left and right screw-receiving screw holes opened around the protruding portion of the cover flange portion 30, which correspond to the screw holes 24 of the support bracket 22. Reference numeral 32 designates a window hole similarly opened in the center of the cover flange portion 30, which serves to allow light from the lamp 16 to pass through.

The filter plate 27 is made of flat glass, and is colored as desired. or,
The convex lens 28 is made of so-called semi-cylindrical optical glass with a flat surface on the side where the light from the lamp 16 enters, and acts to converge the light rays that are transmitted through it and projected onto the wall surface W. A support plate 33 for holding the filter plate 27 and the convex lens 28 is fixed to the body frame 29 as a pair of upper and lower backs, and the filter plate 27 and the convex lens are inserted into a receiving slit 34 opened therein. 28
The upper and lower ends of each are fitted and set. Reference numeral 35 indicates a rubber cushion seat that contacts both upper and lower ends thereof, 36 indicates a cover plate that allows the filter plate 27 and the convex lens 28 to be inserted into and removed from the slit 34 of the support plate 33 from above and below; It is removably fixed to the portion 29 with machine screws 37. In this case, it goes without saying that the filter plate 27 and the convex lens 28 are sequentially arranged in parallel from the position of the lamp 16 with a constant interval maintained therebetween.

As is clear from FIGS. 1 to 5, the lens holder C as a unit body as described above is integrated into the instrument body A.
The cover flange portion 30 is fitted into the front and rear openings of the support bracket 22 through the hole 31, and is screwed into the screw hole 24 of the support bracket 22 so that it can move forward and backward. It will be done. At this time, the body frame portion 29 of the lens holder C is fitted into the hollow inner cylinder 20, and the opening edge thereof comes into contact with the leaf spring 26 fixedly installed on the hollow inner cylinder 20, and the extrusion is caused by this. This will bear the elastic back pressure in the force direction. Therefore, by moving the screw 38 forward and backward with a rotating tool (not shown), the focal length of the convex lens 28 can be freely adjusted in terms of light beam projection onto the wall surface W, and the elasticity of the leaf spring 26 can also be adjusted. As a result, the fitted state of the lens holder C to the instrument body A can be stably fixed and held without fear of wobbling or falling off.

When the lighting device configured as described above is fixedly installed on a wall surface W in a room and the lamp 16 is turned on for use, a pair of lens holders C are fitted into the front and rear openings of the device body A. Since the lamp 16 is attached, the light beam emitted from the lamp 16 is colored by the filter plate 27, and is directed both in the front and rear directions of the device main body A, as shown in FIG. It flows out parallel to the wall surface W, and is converged into a sharp straight line by the convex lens 28.
The beam is projected as if it were creeping towards you, and you can clearly see the contour edge of the bundle of rays. Filter plate 2 in the pair of lens holders C
By varying the 7 colors from each other, even more interesting and new lighting effects can be obtained.

Note that, based on the illustrated embodiment, the instrument main body A
Although it has been described as being used by being attached to the wall surface W in the room, it can also be used by being fixedly installed to the ceiling surface R. Further, in the illustrated embodiment, the leaf spring 26 is attached to the hollow inner cylinder 20 of the instrument body A, but this is welded to the support bracket 22 fixedly installed on the body wall of the instrument body A, so that the leaf spring 26 is attached to the hollow inner cylinder 20 of the instrument body A. It is also possible to arrange the lens holder C so as to contact the cover flange portion 30 of the lens holder C. That is, the cover flange portion 30 of the lens holder C and the middle plate portion 23 of the support bracket 22 in the instrument body A.
A spring material such as a plate spring 26 or a coil spring may be inserted between the front and rear facing sides. This is also because it can be said that the above-mentioned elastic back pressure can be applied to the lens holder C.

As described above, due to the structure of the lighting device according to the present invention, the hollow inner cylinder 20 for heat shielding is assembled and enclosed, so that together with the inner cylinder 20, the two openings are formed at the front and rear parts. The appliance body A is shaped like a hollow cylinder with a heavy structure, and the bottom wall of the appliance body A is connected to the indoor wall surface W and the ceiling surface R.
A disk-shaped mounting base B is detachably attached to the bottom wall of the instrument so that it can be attached to the instrument body A, and a mounting base B is attached to the front and rear openings of the hollow inner cylinder 20 in the instrument main body A. It is equipped with a pair of hollow cylindrical lens holders C, front and rear, which are removably fitted in each case.In the center of the mounting base B, there is a The light source lamp 16 facing the center of the interior of the inner tube 20 and its lamp socket 14 are integrated in a planted structure, and the hollow inner tube 20 is located near the front and rear openings of the device main body A. A pair of left and right lens holder support brackets 22 are fixedly installed facing the gap between the lens holder C and the lens holder C. Inside the lens holder C, there is a substantially semi-cylindrical convex lens 28 whose light incident side from the light source lamp 16 is flat. , and a colored filter plate 27 positioned in parallel on the light incident side, respectively, are fitted to form a unit, and the pair of front and rear lenses of the lens holder C are inserted into the hollow space from the front and rear openings of the instrument body A. The cover flange portions 30 that are fitted into the tubes 20 and integrally protrude outward from each lens holder C are fixed to the lens holder support bracket 22 by screws 38, respectively. It is assembled so that it can move forward and backward in the front and rear directions, and it is installed between the support bracket 22 of the device main body A and the cover flange portion 30 of the lens holder C, which face each other, or integrally protrudes inward from the hollow inner cylinder 20. A spring member 26 inserted between the spring receiving piece 25 and the opening edge of the lens holder C itself, which is inserted between the front and rear sides of the lens holder C, is constantly pushed out against the lens holder C assembled to the device main body A. Because it has been given elastic back pressure in the direction, when it is attached to the wall W or ceiling R for example, to decorate the interior of a show window or various stores, it will accentuate the room with sharp colored light rays. This allows you to create a variety of interesting and innovative lighting effects.

That is, the instrument main body A is a double-structured hollow cylinder type equipped with the hollow inner cylinder 20, and its front and rear parts are open, and the hollow inner cylinder 20 is connected from both the open front part and the open rear part. A pair of front and rear lenses of a lens holder C equipped with a convex lens 28 and a filter plate 27 are fitted, and the device main body A in such a state is attached to an indoor wall surface via a mounting base B attached to the bottom wall. Since it is designed to be installed on W or ceiling surface R, when it is used, as is clear from Fig. 14, the colored light beams are sharpened from both front and rear directions, centering on the light source lamp 16 inside the fixture body A. It will be projected in a straight line and parallel to the wall surface W or ceiling surface R to which it is attached, and in that case, the desired color can be given by the filter plate 27, creating a unique and interesting change. Rich lighting effects can be achieved.

Further, each lens holder C is provided with a convex lens 28 and a filter plate 27,
Assuming that it is formed into a unit body that is separate and independent from the device body A, and that the mounting base B also has a light source lamp 16 and its lamp socket 14,
After all, since they form a separate unit body from the instrument body A, they can be easily and correctly assembled with the instrument body A, and are excellent in mass productivity.

In particular, each lens holder C is screwed into the lens holder support bracket 22 on the instrument body A side from its cover flange portion 30 in a state where it is fitted into the hollow inner tube 20 of the instrument body A so that it can move forward and backward. It is assembled via the screw 38, and elastic back pressure in the pushing direction is applied by the spring material 26 to the lens holder C in the assembled state.
8 from the outside with a rotary tool, the convex lens 28 is projected onto the wall surface W and ceiling surface R.
This has the effect of allowing the focal length of the lens to be adjusted freely and extremely easily in the assembled state.

Furthermore, since the spring member 26 applies elastic back pressure to the lens holder C in the direction of pushing it out from the instrument body A, even when the lens holder C is assembled to the instrument body A, It can effectively absorb vibrations and shocks by itself, and it also has the effect of being able to be held stable at all times without fear of rattling or falling off.
