DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting system for a unit room such as a bathroom unit and a shower room unit.

[0002]

2. Description of the Related Art Conventionally, when a lighting device is installed in a unit room such as a bathroom unit, the lighting device is mounted on a ceiling of the unit room, and wirings and the like are positioned on the ceiling (that is, the wiring device is positioned outside the unit room). ), A light-transmitting cover was attached to a portion of the lighting fixture exposed to the lower surface of the ceiling for waterproofing.

[0003]

On the other hand, in the unit room, a luxurious feeling different from a single ceiling can be exhibited by adopting a double ceiling structure in which another lower ceiling is partially disposed below the ceiling. Although the ceiling is considered, when this double ceiling is used, illumination below the lower ceiling occurs as a new problem.
In other words, when a lighting device such as a downlight is arranged on the upper surface of the lower ceiling and light is emitted from a hole provided in the lower ceiling, the lighting device arranged on the upper portion of the lower ceiling is used in the unit room. Since water or water vapor invades, there is a problem that the waterproofing process is much larger than when a lighting fixture is mounted on a ceiling in a single ceiling.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and it is an object of the present invention to provide waterproofing of a lighting fixture to the same degree as mounting a lighting fixture on a single ceiling. An object of the present invention is to provide a lighting device for a unit room, which can be waterproofed, can provide lighting such as a downlight, and can perform indirect lighting in which light is emitted from between a ceiling and a lower ceiling.

[0005]

According to the lighting device for a unit room of the present invention, a lower ceiling 3 is partially arranged below a ceiling 2 of a unit room 1 and a lighting fixture 4 is attached to the ceiling 2.
A hole 5 is formed in a portion of the lower ceiling 3 corresponding to a position below the lighting fixture 4
And a cylindrical body 6 for preventing light diffusion is protruded upward from the hole 5. By adopting such a configuration, the problem of the above-described conventional example is obtained. To achieve the object of the present invention.

It is also preferable that the lower part of the cylindrical body 6 hangs downward from the hole 5 of the lower ceiling 3, and the cylindrical body 6 is translucent milky white.

[0007]

According to the present invention, the unit room 1
In a double-structured ceiling in which the lower ceiling 3 is partially disposed below the ceiling 2, a lighting fixture 4 is attached to the ceiling 2, and a hole 5 is provided in a portion of the lower ceiling 3 corresponding to a position below the lighting fixture 4. Thus, most of the lighting fixtures 4 are outside the ceiling 2 (that is,
(Outside the unit room 1), the waterproofing process can be simplified. Further, in the double-structured ceiling in which the lower ceiling 3 is partially arranged below the ceiling 2 of the unit room 1 in this way, despite the fact that the lighting fixture 4 is attached to the ceiling 2, the hole 5 By projecting the light diffusion preventing cylinder 6 upward from above, light can be radiated downward from the hole 5 of the lower ceiling 3 as a downlight while preventing light diffusion.

The lower part of the cylindrical body 6 hangs downward from the hole 5 of the lower ceiling 3, and the cylindrical body 6 has a translucent milky white color. Is not diffused along the surface of the lower ceiling 3 immediately below the lower ceiling 3 and is radiated with directivity downward, and the cylindrical body 6 has a translucent milky white color. As a result, the outer surface of the cylindrical body 6 shines pale above the lower ceiling 3, and this pale light illuminates the unit room 1 from between the ceiling 2 and the lower ceiling 3, and Indirect lighting can be expected, and below the lower ceiling 3, the outer surface of the portion hanging down below the lower ceiling 3 of the cylindrical body 6 shines faintly, and this faint light illuminates the surroundings and is not present in conventional downlights. Now you can do interesting lighting.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings. A lower ceiling 3 is partially provided below a ceiling 2 of a unit room 1 such as a bathroom unit or a shower room unit. In the embodiment shown in the attached drawings, an example of a bathroom unit is shown as the unit room 1, and in FIG. The lower ceiling 3 is arranged above the bathtub 8. As shown in FIG. 1, a mounting bracket 11 attached to an end of a panel body 10 constituting the lower ceiling 3 is fixed to a ceiling panel 13 constituting the ceiling 2 with a screw 12. In this case, the panel body 10
May be mounted on the upper end surface of the wall panel 9 of the unit room 1. In FIG. 1, a connection fitting 15 provided on the upper end of the wall panel 9 and a fixing piece 16 provided on the ceiling panel 13 are fixed by screws 12. A gap 18 is provided between the upper end of the side edge of the lower ceiling 3 and the lower surface of the ceiling 2.

A lighting device 4 is attached to a portion above the lower ceiling 3 of the ceiling 2. In this case, when mounting the lighting device 4 on the ceiling 2, most of the lighting device 4 includes the wiring including the wiring. The lower cover 17 having a light-transmitting property is exposed on the lower surface side of the ceiling 2 at the upper surface side of the ceiling 2, and it is only necessary to waterproof the mounting portion around the lower cover 17 having the light-transmitting property. It is like that. A hole 5 is provided in the lower ceiling 3 directly below the lighting fixture 4, and light from the lighting fixture 4 is emitted downward from the hole 5.

A cylindrical body 6 projects upward from the peripheral edge of the hole 5 in the lower ceiling 3, and the upper end of the cylindrical body 6 has a light-transmitting property of the lighting fixture 4 mounted on the ceiling 2 as shown in FIG. Is provided near the lower cover 17. The lower portion of the cylindrical body 6 slightly hangs downward from the hole 5 to form a hanging cylindrical portion 19. In the embodiment shown in FIG. 1, the cylindrical body 6 is provided with a mounting piece 20 on the outer periphery and fixed with a screw 12. The cylindrical body 6 having such a configuration has translucency, and at least the hanging cylindrical section 19 is formed of a milky white material. Of course, the entire cylinder 6 may be formed of a milky white material.

In the above configuration, the light of the luminaire 4 provided on the ceiling 2 illuminates the lower part of the lower ceiling 3 through the cylindrical body 6. In this case, the cylindrical body 6 projects upward from the hole 5, and the upper end of the cylindrical body 6 is close to the light-transmitting lower cover 17 of the lighting fixture 4 attached to the ceiling 2, Most of the light is introduced into the cylindrical body 6 without diffusing the light from the lighting fixture 4, so that the area below the lower ceiling 2 can be efficiently illuminated. Since the cylindrical body 6 has a translucent milky white color, the outer surface of the cylindrical body 6 shines faintly above the lower ceiling 3, and the faint light is transmitted from between the ceiling 2 and the lower ceiling 3. Unit room 1
Will leak inside and illuminate the unit room 1,
Indirect lighting of the ceiling can be expected. Further, below the lower ceiling 3, the outer surface of a portion hanging down below the lower ceiling 3 of the tubular body 6 shines faintly, and this faint light illuminates the surroundings, so that it is possible to provide a quaint lighting that is not present in conventional downlights. .

As described above, the ceiling of the bathroom unit as the unit room 1 is partially double-ceiling, and the lighting below the lower ceiling 3 is down-lighting.
By indirectly illuminating the side from between the upper end of the side end of the lower ceiling 3 and the lower surface of the ceiling 2, a bathroom unit with a luxurious atmosphere that has never been seen before can appear, and comfortable bathing can be performed.

[0014]

According to the present invention, as described above, the lower ceiling is partially disposed below the ceiling of the unit room, the lighting fixture is attached to the ceiling, and the lower ceiling corresponds to the position below the lighting fixture. A hole is provided in the area where the light is to be diffused, and a light diffusion prevention cylinder projects upward from this hole, so that most of the lighting fixtures are located outside the ceiling (ie, outside the unit room). Thus, the waterproofing process can be simplified, and in this way, in the double-structured ceiling in which the lower ceiling is partially arranged below the ceiling of the unit room, the lighting fixture is attached to the ceiling instead of the lower ceiling. Despite being
By projecting the light diffusion preventing cylinder upward from the hole in the lower ceiling, light can be emitted downward as a downlight from the hole in the lower ceiling while preventing light diffusion.

In the case where the lower part of the cylindrical body hangs downward from the hole in the lower ceiling and the cylindrical body has a translucent milky white color, the light radiated downward from the hole does not pass through the lower ceiling. It is irradiating with directivity downward without being diffused along the lower ceiling surface immediately on the lower surface, it can be efficiently illuminated, and furthermore, the cylinder has a translucent milky white color Above, the outer surface of the cylinder shines pale above the lower ceiling, and this faint light illuminates the unit room from between the ceiling and the lower ceiling, and indirect lighting of the ceiling is expected. In addition, below the lower ceiling, the outer surface of the part hanging below the lower ceiling of the cylindrical body glows faintly,
This faint light illuminates the surroundings, and can provide quaint lighting not found in conventional downlights.
