Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for illuminating an atrium space. In particular, the present invention relates to a structure for achieving both the effect of expanding the space upward and securing the brightness of the living space, which is an essential function of the lighting fixture.

[0002]

2. Description of the Related Art Conventionally, it has been known that a space forming an entrance hall, a living room, a dining room, and the like of a house is an atrium space extending from a first floor portion to a second floor portion. In this way, a feeling of openness is obtained in the space to improve the livability.

[0003] In these spaces, a window for lighting is generally provided at a high position on the wall surface, and the sunlight entering through the window can ensure the brightness of the upper space in the room. ing.

[0004]

As described above, since sunlight illuminates the open space during the daytime,
It is possible to feel the upward expansion of the space, and the brightness of the living space (the lower part of the space) is also ensured well, so that the brightness at hand when reading or reading can be obtained satisfactorily.

[0005] By the way, since the sunlight cannot be obtained at night, it is necessary to illuminate the open space with a lighting fixture. In this case, if the arrangement of the lighting equipment in the atrium and the direction of the illumination light were made the same as in a general room lighting method, it would be necessary to ensure that the effect of expanding the space upwards and maintaining the brightness at hand You cannot achieve both.

For example, when a lighting fixture is mounted on a ceiling surface, the distance from the ceiling surface to the floor surface is 2.
Since the distance is about 3 m, the irradiation light from the lighting fixture attached to the ceiling surface can be sufficiently reached. Also, light reflected from the ceiling surface reaches near the floor surface, and this reflected light also contributes to securing brightness at hand. On the other hand, when lighting fixtures are installed on the ceiling surface of the stairwell, the upper part of this space can be illuminated well and the upward expansion of the space is possible, but from the lighting fixture installation position to the floor surface May not be able to obtain sufficient brightness at hand because of the long distance.

Conversely, when a lighting fixture is mounted at a relatively low position on the wall surface of the stairwell and the light is emitted downward, the brightness at hand is good, but the ceiling becomes dark and the space becomes dark. Cannot be directed upward.

[0008] As described above, regarding the lighting of the atrium space, a lighting method different from that of a general room is required. The inventors of the present invention have studied an illumination structure that is optimal for this type of space with respect to the illumination of the atrium space.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide lighting for a stairwell, which is capable of achieving the effect of expanding the space upward and ensuring the brightness at hand.

According to this specific matter, the ceiling surface and the wall surface of the atrium space are illuminated by the spotlight. By using this spotlight, it is possible to perform a unique effect such as partially shading the illuminated surface (ceiling surface or wall surface).

According to a fifth aspect of the present invention, in the first aspect, a part of the wall of the atrium space is extended toward the indoor side, and a second lighting device is provided on a lower surface of the extended portion. And down light.

According to this particular feature, it is possible to irradiate the second lighting fixture with the illumination light downward at a relatively low position. In addition, since the lighting fixture is not supported by brackets or the like at a relatively low position on the wall, it does not cause a feeling of protrusion from the wall of the lighting fixture, and the brightness at hand while ensuring the appearance of the wall is good. Can be secured sufficiently.

According to a sixth aspect of the present invention, in the first aspect, the first lighting device is a fluorescent lamp.

According to this specific matter, a relatively wide range of illumination can be performed by the first lighting fixture, and it is possible to produce a space different from the case where a spotlight is used.
