Japanese Utility Model Publication No. 4-125765

In the conventional structure shown in FIG. 19, the horizontal mirror 52 changes in width depending on the size of the bathroom. Therefore, in order to illuminate the upper and lower surfaces uniformly, one horizontal fluorescent lamp 56, 56 is not sufficient. There are cases where a plurality of lamps are required, and the long fluorescent lamps 56 are difficult to handle.
Further, even in the structure disclosed in Patent Document 1, a portion near the illumination is brightened, but a portion away from the illumination is extremely dark, and it is difficult to uniformly illuminate the whole. was there.

  The present invention has been devised in view of the above-mentioned conventional problems, and is intended to provide an indirect lighting device for bathrooms that can uniformly illuminate the upper and lower surfaces without using a long fluorescent lamp, According to the first aspect of the present invention, a light source is provided vertically on at least one end of the left and right ends of the box projecting from the wall surface of the bathroom, and the light emitted from the light source into the box is changed to the horizontal light up or down. In the indirect lighting device for a bathroom configured to reflect the upper and lower surfaces of the box by reflecting vertically with a reflector provided obliquely to reflect in the direction, the reflector is provided at the opposite end of the light source. The reflector is provided obliquely from the upper and lower surfaces toward the center of the box, and the size of the reflector is a distance of 40 to 60% of the distance between the end facing the light source and the horizontal distance. It is set to the size of.

A second aspect of the present invention is that the reflecting surface of the reflecting plate is formed in a concave curved surface.
According to a third aspect of the present invention, a light source is provided vertically on at least one lateral end of the box projecting from the wall surface of the bathroom, and at least above the box by light irradiated from the light source through the light emitting surface into the box. In the indirect lighting device for a bathroom configured such that the lower surface shines, the light emitting surface is subjected to a process of bending the light irradiated into the box toward the center in the vertical direction.

According to a fourth aspect of the present invention, a light source is provided vertically on at least one lateral end of the box projecting from the wall surface of the bathroom, and at least above the box by light emitted from the light source into the box through the light emitting surface. In the indirect lighting device for a bathroom configured such that the lower surface shines, the light transmission amount on the upper and lower ends of the light emitting surface is configured to be reduced from the central side.
A fifth aspect of the present invention is that a mirror is provided on the front surface of the box.

  In the present invention, the reflector provided in the box is provided at the opposite end of the light source, the reflector is provided obliquely from the top and bottom surfaces toward the center of the box, and the size of the reflector is horizontal. Since the distance is set to be 40-60% of the distance between the end facing the light source and the end facing the light source, the light emitted from the light source vertically provided on one end side of the box is Irradiated inside the body, reflected by the reflector provided inside the box and can shine the upper and lower surfaces, the part away from the light source can not be dark, and the upper and lower surfaces can be illuminated uniformly Become.

  In addition, since the reflecting surface of the reflecting plate is formed into a concave curved surface, the reflecting plate having a concave curved surface can collect light well on the upper and lower surfaces away from the light source, and the upper and lower surfaces of the box body are uniform. It will be able to shine.

  In addition, the light emitted from the light source to the box through the light emitting surface is centered in the vertical direction by performing a process for bending the light emitted from the light source toward the center in the vertical direction on the light emitting surface. Because the light is irradiated toward the light source, the light can reach a location far from the light source of the box, the light can be prevented from being concentrated near the light source, and the upper and lower surfaces can be illuminated uniformly. .

  Moreover, since the light-transmitting surface is configured so that the light transmittance on the upper and lower ends of the light-emitting surface is reduced from the center side, the light-emitting surface has a small amount of light on the upper and lower-end sides and a large amount of light on the center side. Light travels far into the box through the center, and the light does not concentrate only near the light source, and the top and bottom surfaces of the box can be illuminated uniformly.

In addition, as shown in FIG. 12, four reflecting plates 30 can be assembled | attached and arrange | positioned at the horizontal direction center part in the box 6 in the rhombus shape.
As shown in the schematic diagram of FIG. 13, in the configuration in which the rhomboid reflector 30 is provided in the box 6 and the left light source box 10 and the right light source box 11 are provided on the left and right sides of the box 6 as described above. From the light sources 22 and 22 arranged in the left light source box 10 and the right light source box 11, light is irradiated into the box body 6 through the left and right light emitting surfaces 24 and 24, respectively. The reflected light is reflected by the reflecting plate 30 so that the upper and lower surfaces of the box 6, that is, the surfaces of the translucent milky white top plate 12 and the bottom plate 13 can be brightly illuminated.

In this example, the reflecting plate 30 is 40 to 60% of the distance b from the center of the reflecting plate 30 to the tip in the lateral direction with respect to the distance a from the light emitting surface 24 to the center of the reflecting plate 30 in FIG. Is set to the size of the distance.
As a best mode, it is preferable that the distance of b is 1/2 with respect to a. If the reflector 30 is set to such a size, the box from the light source 22 through the light emitting surface 24 is used. The light radiated into the body 6 is well reflected on the upper and lower surfaces and can brightly illuminate the upper and lower surfaces. Particularly, the upper and lower surfaces of the central portion in the horizontal direction where the reflector 30 is provided are bright, On the reflecting plate 30 side, the upper and lower surfaces can be illuminated with substantially uniform light, and the upper and lower surfaces can shine evenly and good indirect illumination can be obtained.

The distance is set to 40-60% of the distance.

Even in such a configuration, the light from the light source 22 is irradiated into the box 6 through the light emitting surface 24, and the light is reflected up and down through the upper reflecting plate 30 a and the lower reflecting plate 30 b. The upper and lower surfaces on the right end side that are far from the center can also be brightly illuminated, and the entire upper and lower surfaces shine with uniform brightness, resulting in good indirect illumination.
Further, in FIG. 15, the upper reflecting plate 30a and the lower reflecting plate 30b are formed in a parabolic concave curved surface, and by making such a concave curved surface, it is possible to reliably move to the upper and lower surfaces on the distal side of the box 6. The light from the light source 22 can be delivered, and the upper and lower surfaces on the end side can be illuminated with uniform brightness.

In addition, by devising the respective light emitting surfaces 24 of the left light source box 10 and the right light source box 11 described above, the light from the light source 22 can be delivered farther, and the upper and lower surfaces far from the light source 22 can be brightly illuminated. It will be possible.
That is, FIG. 16 shows a schematic diagram of the left light source box 10, but the light emitting surface 24 is formed of a resin lens, and is integrally formed inside the light emitting surface 24, and the light from the light source 22 is centered in the vertical direction. The condensing lens part 24a which can be made to condense can be formed.

  Furthermore, a sawtooth condensing lens portion 24a as shown in FIG. 17 may be integrally formed on the inner side of the light emitting surface 24, and the light from the light source 22 is condensed at the central portion in the vertical direction so that the light is far away. , And the upper and lower surfaces of the distant position can be illuminated brightly.

  Furthermore, as shown in FIG. 18, the upper and lower ends of the lens forming the light emitting surface 24 are formed into thick portions 24c, 24c, and the central portion in the vertical direction is formed into a thin portion 24b having a thin thickness. The light transmission through the thin portion 24b may be designed to be larger than that at the upper and lower ends. If such a light emitting surface 24 is used, the light transmission at the upper and lower ends is small and the transmission on the center side is small. Since the amount of light is large, light passes through the center side of the light emitting surface 24 and reaches far into the box 6, so that the light does not concentrate only near the light source 22, and the upper and lower surfaces of the box 6 are made uniform. It will be able to shine.

The light emitting surface 24 as shown in FIGS. 16, 17, and 18 is provided, and the upper and lower surfaces far from the light source 22 can be more reliably illuminated brightly by arranging the reflector 30 described above. It becomes.
In this example, the shape of the lens forming the light emitting surface 24 is devised, but the light emitting surface 24 may be subjected to a process of bending light toward the center in the vertical direction.
