Description

[Technical field]

[0001] The present invention relates to lighting provided in a building having a fire compartment. [Background technology]

[0002] It is known that hotels, hospitals, apartment buildings, and other buildings with fire-resistant or semi-fire-resistant structures are provided with fire compartments to prevent the spread of fire in the event of a fire, as required by the Building Standards Act (see, for example, Patent Document 1).

[0003] Meanwhile, as lighting used in buildings such as hotels, hospitals, and apartment buildings, a configuration in which a light source is arranged inside a lighting box provided on the ceiling or wall is known (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2015-94101 A [Patent Document 2] JP 2010-177145 A Summary of the Invention [Problem to be solved by the invention]

[0005] By configuring the lighting box to be embedded in the ceiling of a corridor, for example, and to extend straight along the wall, the lighting can be arranged in a continuous linear manner, thereby improving the aesthetic appearance of the lighting.

[0006] However, in buildings with fire compartments, if the lighting is arranged in a continuous linear fashion, the lighting boxes may be arranged across the fire compartment. In this case, in order to prevent the fire from spreading through the inside of the lighting boxes, the lighting boxes are partitioned into one side and the other side of the fire compartment by a partition wall that constitutes the fire compartment together with the fire door. Therefore, there is a problem in that the lighting appears discontinuous at the partition wall that constitutes the fire compartment, degrading the aesthetics.

[0007] The present invention has been made in consideration of such problems, and has an object to improve the aesthetic appearance of lighting arranged in a straight line across a fire compartment. [Means for solving the problem]

[0008] The lighting of the present invention is lighting installed in a building having a fire compartment, and is characterized in that it comprises a first lighting box provided on one side of the fire compartment and having a first light source arranged therein, a second lighting box provided on the other side of the fire compartment and connected to the first lighting box and having a second light source arranged therein, and a partition wall provided between the first lighting box and the second lighting box and which constitutes the fire compartment together with a fire door, and mirrors are provided on both sides of the partition wall.

[0009] In the lighting of the present invention having the above configuration, it is preferable that the first lighting box and the second lighting box are embedded in a ceiling and extend along a wall.

[0010] In the lighting of the present invention having the above-mentioned configuration, it is preferable that the first lighting box and the second lighting box are configured for indirect lighting. Effect of the Invention

[0011] According to the present invention, it is possible to improve the aesthetic appearance of lighting arranged in a straight line across a fire compartment. [Brief description of the drawings]

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A lighting device according to an embodiment of the present invention will now be described in detail with reference to the drawings.

[0014] 1 is a building of fire-resistant or semi-fire-resistant construction, such as a hotel, hospital, apartment building, etc. The building 1 is made of reinforced concrete, for example, and has a straight corridor 2.

[0015] As shown in Figures 2 and 3, building 1 has a fire compartment 10 that is set up to cross corridor 2. The installation of fire compartment 10 in building 1 is required by the Building Standards Act, and by dividing building 1 into two sides separated by fire compartment 10, the spread of fire to the entire building 1 can be suppressed in the event of a fire.

[0016] A fire door 11 is provided in the corridor 2. The fire door 11 is embedded flush into one wall 3 of the corridor 2 and is supported by a hinge 12 so as to be rotatable (openable and closable). As shown by the two-dot chain line in FIG. 3, the fire door 11 can rotate about the hinge 12 to close the corridor 2. By closing the corridor 2, the fire door 11 forms part of a fire compartment 10 set to cross the corridor 2. Note that a frame 13 that engages with the closed fire door 11 may be provided on at least a part of the walls 3, 4, ceiling 7, or floor 8 of the corridor 2.

[0017] Although not shown in detail, the fire compartment 10 is configured to divide the building 1 into one side and the other side by the fire compartment 10 using various parts or components, such as the fire door 11 and walls 5 and 6 connected to the walls 3 and 4 of the corridor 2.

[0018] The corridor 2 is provided with lighting 20 according to one embodiment of the present invention. The lighting 20 is intended to illuminate the interior space of the corridor 2, and is configured to be arranged in a straight line that extends continuously in the direction of the corridor 2. This configuration makes the lighting 20 aesthetically pleasing and in harmony with the corridor 2.

[0019] 2 and 4, the lighting 20 has a first lighting 21a provided on one side of the corridor 2 across the fire compartment 10, and a second lighting 21b provided on the other side of the corridor 2 across the fire compartment 10. That is, the lighting 20 is configured such that the first lighting 21a and the second lighting 21b are arranged in a straight line that extends continuously across the fire compartment 10.

[0020] The first lighting 21a has a first lighting box 22a and a first light source 23a. The first lighting box 22a is an elongated box shape with a U-shaped cross section, and is embedded in the ceiling 7 with an opening facing downward on one side of the corridor 2 sandwiching the fire compartment 10, and is disposed along the wall 4. The first light source 23a is formed in an elongated shape using, for example, an LED light source, and is disposed inside the first lighting box 22a. A configuration in which a plurality of first light sources 23a are arranged in the longitudinal direction inside the first lighting box 22a may be used. The first light source 23a is not limited to an LED light source, and may be various light sources.

[0021] In this embodiment, a plate-shaped base 24a is attached to the first lighting box 22a so as to close a part of the opening of the first lighting box 22a, and the first light source 23a is installed on the base 24a. As a result, the first lighting 21a is configured so that light emitted from the first light source 23a is reflected inside the first lighting box 22a and is irradiated toward the inside of the corridor 2 from the downward opening of the first lighting box 22a. In other words, the first lighting 21a to the first lighting box 22a are configured as indirect lighting.

[0022] Similarly to the first lighting 21a, the second lighting 21b has a second lighting box 22b and a second light source 23b. The second lighting box 22b has a long box shape with a U-shaped cross section, the same as the first lighting box 22a, and is embedded in the ceiling 7 with an opening facing downward on the other side of the corridor 2 across the fire compartment 10, and is arranged along the wall 4. That is, the second lighting box 22b is provided in a straight line connected to the first lighting box 22a across the fire compartment 10. Similarly to the first light source 23a, the second light source 23b is also formed in a long shape, for example, by an LED light source, and is arranged inside the second lighting box 22b. A configuration in which a plurality of second light sources 23b are arranged in the longitudinal direction inside the second lighting box 22b may be used. The second light source 23b is not limited to an LED light source, and may be various light sources.

[0023] In this embodiment, similar to the first lighting box 22a, the second lighting box 22b is provided with a plate-shaped base 24b so as to close a part of the opening of the second lighting box 22b, and the second light source 23b is installed on the base 24b. As a result, the second lighting 21b is configured such that the light emitted by the second light source 23b is reflected inside the second lighting box 22b and is irradiated from the downward opening of the second lighting box 22b toward the inside of the corridor 2. That is, the second lighting 21b to the second lighting box 22b are also configured as indirect lighting like the first lighting 21a to the first lighting box 22a.

[0024] In addition, the first lighting 21a and the second lighting 21b are not limited to the indirect lighting described above, and may be configured as direct lighting in which light emitted from the first light source 23a to the second light source 23b is directly irradiated toward the inside of the corridor 2 from the openings of the first lighting box 22a to the second lighting box 22b.

[0025] As shown in Fig. 2 and Fig. 5, a partition wall 30 is provided between the first lighting box 22a and the second lighting box 22b. The partition wall 30 has a rectangular shape corresponding to the cross-sectional shapes of the first lighting box 22a and the second lighting box 22b, and closes the end of the first lighting box 22a facing the second lighting box 22b and the end of the second lighting box 22b facing the first lighting box 22a. The partition wall 30 is disposed along a set portion of the fire compartment 10. As shown in Fig. 6, when the fire door 11 is closed, the partition wall 30 forms the fire compartment 10 together with the fire door 11.

[0026] By providing a partition wall 30 between the first lighting box 22a and the second lighting box 22b, even if the lighting 20 is arranged in a straight line extending continuously across the fire compartment 10, the spread of fire through the inside of the first lighting box 22a or the second lighting box 22b in the event of a fire can be suppressed, and the fire compartment 10 can be reliably constructed.

[0027] 5, in the lighting 20 according to this embodiment, the partition wall 30 provided between the first lighting box 22a and the second lighting box 22b is configured to have mirrors 31 provided on both sides thereof. In this embodiment, the partition wall 30 is configured to have a rectangular plate material 32 made of, for example, steel and having fire resistance sufficient to constitute the fire compartment 10, and a pair of mirrors 31 formed in the same shape as the plate material 32 and attached to both sides of the plate material 32.

[0028] With this configuration, the first light 21a is reflected in the mirror 31 facing the first light 21a of the partition wall 30, and the second light 21b is reflected in the mirror 31 facing the second light 21b of the partition wall 30. Therefore, when the partition wall 30 is viewed from one side where the first light 21a is provided with respect to the fire compartment 10 of the corridor 2, the first light 21a is reflected in the mirror 31 of the partition wall 30, making it look as if the first light 21a extends continuously beyond the partition wall 30. Similarly, when the partition wall 30 is viewed from the other side where the second light 21b is provided with respect to the fire compartment 10 of the corridor 2, the second light 21b is reflected in the mirror 31 of the partition wall 30, making it look as if the second light 21b extends continuously beyond the partition wall 30.

[0029] As described above, in the lighting 20 of this embodiment, the partition wall 30 provided between the first lighting box 22a and the second lighting box 22b to form the fire compartment 10 is configured with mirrors 31 provided on both sides thereof, so that the fire compartment 10 is reliably formed as a configuration in which the partition wall 30 to form the fire compartment 10 is provided between the first lighting box 22a and the second lighting box 22b, while the lighting 20 is visually perceived as being arranged in a straight line across the fire compartment 10, thereby enhancing the aesthetic appearance.

[0030] Furthermore, in the lighting 20 of this embodiment, the first lighting box 22a and the second lighting box 22b are configured to be embedded in the ceiling 7 and extend along the wall 4, so that the lighting 20 blends in with the appearance of the corridor 2 to further enhance the aesthetic appearance of the lighting 20, while the fire compartment 10 can be more effectively configured by the partition wall 30.

[0031] Furthermore, in the lighting 20 of this embodiment, the first lighting box 22a and the second lighting box 22b are configured to provide indirect lighting, so that the aesthetic appearance of the lighting 20 can be further improved.

[0032] The present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the spirit and scope of the present invention.

[0033] For example, in the above embodiment, the lighting 20 is installed in the corridor 2 of the building 1, but this is not limited thereto, and the lighting 20 may be installed in various places, such as rooms and halls of the building 1, as long as it is installed across the fire compartment 10.

[0034] In addition, in the above embodiment, the lighting 20 is configured such that the first lighting box 22a and the second lighting box 22b are embedded in the ceiling 7 and extend along the wall 4, but this is not limiting, and the lighting 20 may be configured such that the first lighting box 22a and the second lighting box 22b are embedded in the wall 4 and extend along the ceiling 7. Furthermore, the first lighting box 22a and the second lighting box 22b may be installed on the surface of the ceiling 7 or the wall 4 without being embedded in the ceiling 7 or the wall 4. Furthermore, the first lighting box 22a and the second lighting box 22b may be provided in an intermediate portion of the ceiling 7 or the wall 4 without being along the wall 4 or the ceiling 7.
