Reference numeral 21 denotes a hanging bolt 2 formed on the mounting piece 17 of the hanging fitting 3.
This is a cut arrow part for escape.

Reference numeral 20 denotes a U-shaped cover placed on the upper surface of the lighting fixture main body 6.

Reference numeral 8 denotes a pyramid-shaped reflector plate with an open bottom surface, which is attached to the lower surface of the lighting device main body 6. The upper surface of this reflector plate 8 is closed, and an insertion hole 22 through which the socket 14 is inserted is bored in the center of the upper surface. An opening edge 7 extending outward is formed on the periphery of the lower surface of the reflecting plate 8.

Then, the opening edge 7 of the reflecting plate 8 is locked to the periphery of the opening of the ceiling material 1, and the socket 14 is inserted into the insertion hole 22 on the upper surface of the reflecting plate 8, and the socket 14 is screwed in via the coil spring 24. The reflector plate 8 is attached to the lower surface of the lighting device main body 6 by screwing the fitting 23 into a threaded portion on the circumferential surface of the socket 14.

In addition, at the lower part of each inner surface of the square reflecting plate 8, there are two L
Hanging rods 9 each having one end rotatably supported on the shaft 26 of the shaped piece 25 are attached.

This hanging rod 9 is bent into an L shape, and the lower end thereof is curved into a circular shape.

Reference numeral 11 denotes a frame body suspended below the reflector plate 8 by a hanging rod 9. A screw rod 29 is formed at the upper part of each inner surface of this frame body 11, and a fifth threaded rod 29 is formed on the upper part of each inner surface of this frame body 11. As shown in the figure, the end of the hanging rod 9 is inserted and the frame 11 is suspended using the spring washer 27 and the wing nut 28.

The lower opening of the frame 11 is smaller than the upper opening, and a louver 10 or a light-transmitting panel is attached to the surface of the lower opening by dropping it into the upper opening after the frame 11 is attached to the reflector plate 8.

Note that 30 is a lamp. The upper opening of the frame 11 is considerably larger than the lower opening of the reflecting plate 8.

Then, as shown in FIG. 6, the lower opening edge of the ceiling material 1 (
The upper opening edge of the frame 11 (point B in the figure) is closer than the line connecting the lower opening edge (point C in the figure) of the reflector 8
A frame body 11 is suspended by a hanging rod 9 so that the frame body 11 is positioned above.

In other words, the side wall of the frame 11 prevents the light from the lamp 30 from directly entering the eye from below the ceiling material 1, and further improves the effect of the light as will be described later.

When adjusting the height of the lighting fixture body 6, loosen the tightening bolt 5 and move the lighting fixture body 6 upward or downward, as shown in FIG. 4, and then tighten the tightening bolt 5 at an arbitrary position. Fix the lighting fixture body 6.

At this time, only the lighting fixture main body 6 moves up and down, and the reflecting plate 8 does not move because its mouth edge 7 is locked to the periphery of the opening of the ceiling material 1.

Since the reflector plate 8 is attached to the lighting fixture main body 6 via the coil spring 24, the reflector plate 8 is closely fixed to the ceiling surface.

Figure 6a shows a case where the lighting fixture body 6 is mounted high, and the center of the light of the lamp 30 (A in the figure) is also located upwards, so that the lower surface of the ceiling material 1 is placed as shown in the figure. A dark part 8 is formed by the shadow of the bright part opening and the frame body 11.

At this time, the four direct lights from the lamp 30 are confined to the mouth of the reflector 8 due to the side wall of the frame 11, and no direct light enters the eyes. The light is reflected on the upper and lower surfaces of the reflector plate 8 through the inner wall surface of the frame body 11, and is also reflected on the outer wall surface of the frame body 11 by diffuse reflection at the mouth portion of the reflector plate 8. It also illuminates, increasing the effect of light production.

Furthermore, of course, the upper opening edge of the frame 11 (point B) is closer to the line connecting the lower opening edge of the ceiling material 1 (point A) and the lower opening edge of the reflecting plate 8 (point C). is located above, the reflecting surface above the point on the reflecting plate on the line connecting point C and point B shines.

Further, FIG. 6b shows a case where the lighting fixture main body 6 is mounted low, and the center of the light of the lamp 30 is also located at the bottom.

Therefore, on the lower surface of the ceiling material 1, there are fewer bright areas and more dark areas shaded by the frame 11,
In this way, the positions of the shadows of the light generated on the inclined surface of the hollow ceiling material 1 blocked by the frame 11 are different, and a light effect can be produced.

FIGS. 7 and 8 show another embodiment in which the lower end portion of the hanging rod 9 connecting the reflector 8 and the frame 11 is curved in a spiral shape as shown in FIG. be.

Then, the tip is wound approximately once and bent so that the tip is stepped from the main body of the hanging rod 9, as shown in FIG. 7b.

Therefore, when this part is fitted into the threaded rod 29 of the frame 11 and tightened with the wing nut 28 as shown in FIG. When tightened, the frame body 11 is firmly fixed to the hanging rod 9 without using a separate spring washer.

Further, when the frame body 11 is hung, the frame body 11 does not swing, and there is no need to insert a spring washer, which improves installation workability.

As mentioned above, the present invention consists of a ceiling material having a substantially trapezoidal frame shape in cross section, which is installed on the ceiling surface, the lower end of which is fixed to an opening in the upper surface of the ceiling material, and the upper part of which is suspended from above the ceiling material. The lighting consists of a hanging fitting attached to a hanging bolt, a vertically long elongated hole drilled in the hanging fitting, which is movable up and down with a tightening bolt, and a socket for attaching a lamp to the bottom of the hanging fitting. The main body of the lighting device has an opening at the bottom, and the edge of the opening is locked and fixed to the opening on the top surface of the ceiling material, and is arranged on the bottom surface of the lighting device body to reflect the light from the lamp disposed inside the lighting device. A reflector with an opening on the bottom, a mounting bracket that fixes the reflector to the socket of the lighting equipment body inserted through the insertion hole drilled in the upper surface of the reflector via a coil spring, and a mounting bracket that fixes the reflector from the reflector to the lower part of the reflector. It is suspended from a hanging rod, has a louver or panel attached to its lower surface, and has a rectangular frame with a lower opening and a frame whose upper opening is larger than the upper opening of the ceiling material. The board can be easily attached to the ceiling material and the lighting fixture body, and by simply loosening the tightening bolts that secure the lighting fixture body and the hanging bracket, the lighting fixture can be easily attached to the length of the elongated hole in the hanging bracket. The height of the main body can be adjusted vertically, and the reflector is attached to the socket with a mounting bracket via a coil spring.
This has the advantage that the reflector can be fixed to the socket without wobbling even if the lighting fixture body is moved up and down.

In addition, the edge of the upper opening of the frame is positioned above the line connecting the lower opening edge of the ceiling material and the lower opening edge of the reflector, so the light from the lamp is directed through the upper opening of the frame. The edge of the opening hits the reflective plate above the line connecting the edge of the opening and the lamp, and the direct light is blocked by the frame and does not directly enter the eye, and the direct light from the lamp is blocked by the frame. The light is reflected to the upper and lower surfaces of the reflector through the inner wall surface of the reflector, and even in the portions of the reflector that are directly hit by the light, the light is diffused and reflected to the outer wall of the frame, making the outer wall of the frame shine as well. This increases the effect of light production.

Furthermore, since the upper opening edge of the frame is located above the line connecting the lower opening edge of the ceiling material and the lower opening edge of the reflector, the lower opening edge of the reflecting plate The reflective surface of the ceiling material above the point of the reflector plate on the line connecting the upper opening edge of the frame shines, and in this way, the indirect lighting that is integrated with the ceiling material and the frame increases the light production effect. Moreover, by adjusting the lighting fixture body up and down, the position of the shadow formed on the lower surface of the ceiling material can be varied depending on the relationship between the frame and the lamp light source, and the advantage is that it can create various lighting effects of light and shadow. has.
