Description

  The present invention relates to an illumination system capable of forming a planar light emitting area in the air using a light scattering phenomenon and partitioning a room space with a light curtain.

  In recent years, usage methods of houses have been diversified, and a plurality of people in a large living-dining area may perform different activities. For example, a child eats in a dining room while an adult relaxes in a living room. In such a case, there is a need for an adult in the living room to have a feeling of being in an open space, a feeling of being in a private space, and to feel the presence of a child. As a tool to meet this need, there are thin curtains and partitions that transmit light to the extent that the silhouette is visible. As described above, partitioning a room so that the presence of each other can be easily confirmed from both sides of the partition without blocking sound and light is hereinafter referred to as semi-separation.

For example, a partition in which two glass plates are erected in a partition shape at a predetermined interval is known as a partition that transmits light (see, for example, Patent Document 1). In this partition, it is possible to protect the separated internal privacy by appropriately attaching a translucent film on the surface of the glass plate.

  However, since the installation positions and sizes of the curtains and partitions are semi-fixed, various problems occur when trying to use the room widely without using them. For example, if it is a cloth curtain, it can be collectively moved to the wall when not in use, but the gathered curtain has a considerable volume, so that it rises from the wall surface and impairs the interior of the room. In the case of a partition, a person must be taken out of the room when not in use.

  Furthermore, the semi-fixed partition means such as the curtain and the partition have the inconvenience that they become an obstacle when cleaning the room and the height position of the partition cannot be changed.

  Therefore, the present invention solves the above-mentioned problems, and when used, an area that shines in a plane is generated in the air, so that the interior of the room can be semi-separated, and the interior of the room is not impaired when not in use. It is an object to provide a lighting system that does not disturb the user.

  In order to achieve the above object, the invention of claim 1 includes a particle group generation device that generates particle groups, and a lighting device that irradiates light to the particle groups generated by the particle group generation device. In the illumination system, the particle group generation device discharges the particle group in a planar shape, and the lighting device irradiates light having a wavelength equal to or smaller than the particle diameter of the particles generated by the particle group generation device. It is characterized by that.

  According to a second aspect of the present invention, in the illumination system according to the first aspect, the particle group generation device includes a regulating plate that regulates a traveling direction of the particle group so that the particle group is planar. .

  According to a third aspect of the present invention, in the illumination system according to the first or second aspect, the particle group generation device discharges the particle group in the same direction as the direction in which the particle group falls due to its own weight. .

  According to the invention of claim 1, since the particle group discharged from the particle group generator is irradiated with light having a wavelength equal to or smaller than the particle diameter, the light is scattered by the particle and a region that shines in a plane is formed in the air. The room can be semi-separated. When not in use, the area that shines in a plane disappears, so that the interior of the room is not impaired and does not interfere with cleaning.

  According to invention of Claim 2, since the advancing direction of a particle group is regulated and regulated with a control board, the shape of the area | region which shines is formed correctly in planar shape.

  According to the invention of claim 3, since the particle group is discharged in the direction of dropping due to its own weight, it is possible to suppress the dissipation of the particle group below, and to prevent the planar shape of the shining region from collapsing. Can do.

(First embodiment)
Hereinafter, an illumination system according to a first embodiment of the present invention will be described with reference to FIGS. 1 and 2. As shown in FIG. 1, the illumination system 1 of the present embodiment includes a particle group generation device 3 that generates a particle group 2 and a large number of particles such as a gas substance generated by the particle group generation device 3. And a lighting fixture 5 that irradiates the particle group 2 with light 4. The particle group generator 3 discharges the particle group 2 in a planar shape, and the lighting fixture 5 irradiates light 4 having a wavelength equal to or smaller than the particle diameter of the particles generated by the particle group generator 3. Since the wavelength of the light 4 is equal to or smaller than the particle diameter, a Mie scattering phenomenon occurs, and the particle group 2 in the region 6 irradiated with the light 4 shines like a curtain of light, and the inside of the room 7 is semi-separated. Can do.

  In the room 7 in which the lighting system 1 is installed, a 3 tatami mat floor 9 is provided at one corner of the board floor 8, and furniture such as a sofa 11 is arranged on the board floor 8. The particle group generation device 3 is embedded in a ceiling 12 immediately above the tatami floor 9 so that the portion of the tatami floor 9 can be partitioned as a Japanese-style space, and the main body 13 of the particle group generation device 3 is L-shaped. Installed on the mold. The luminaire 5 is a spotlight having a structure in which the light irradiation direction can be tilted up and down, and is mounted suspended from the ceiling 12.

  As shown in FIG. 2, the particle group generation device 3 includes a main body 13 and a gas substance supply device 15 that supplies a gas substance to the main body 13 via a hose 14. The main body 13 has a duct-like elongated casing 16 and includes eight spray ports 17 for discharging a gas substance on the lower surface 16a. In FIG. 2, one of the main bodies 13 arranged in an L shape is shown as a representative. In this embodiment, the gas substance is carbon dioxide, and the carbon dioxide molecules discharged from the spray port 17 become the particle group 2.

  A regulation plate 18 that regulates the traveling direction of the particle group 2 discharged from the spray port 17 is fixed to both side surfaces 16 b of the housing 16. The restriction plate 18 is made of, for example, a thin transparent plate made of acrylic. The restriction plate 18 is equivalent to the length of the housing 16 and has a flat plate shape extending in the direction directly below from the side surface 16b, but may have other shapes. For example, it may have a tapered shape that decreases as the distance t between the restriction plates 18 on both sides goes downward, or the restriction plate 18 itself may be curved. Alternatively, the restriction plate 18 may be fixed to the housing 16 in a hinge shape so that the restriction plate 18 is movable, and may be periodically swung by a drive mechanism (not shown) having a motor. In this case, the traveling direction of the particle group 2 is periodically oscillated, and the region 6 itself that shines in a plane is oscillated.

  The gas substance supply device 15 includes a tank 19 for storing the gas substance, a drive pump 21 for sending the gas substance to the main body 13 of the particle group generation device 3, and an operation unit 22 for starting and stopping the operation of the drive pump 21. And comprising. The tank 19 and the drive pump 21 are installed behind the ceiling or inside the ceiling 12, and the operation unit 22 is provided on the wall surface of the room 7.

  The gas substance is a low-boiling substance, and it is preferably a colorless and odorless material without affecting the health of the human body and animals and the growth of plants. Further, a gas substance such as carbon dioxide has a particle diameter of 0.05 to 5 μm when discharged from the spray port 17.

  The luminaire 5 includes a spotlight main body 23 and an operation unit 24 for the user to adjust the light control and tilt angle α of the spotlight main body 23. The spotlight main body 23 incorporates a known drive mechanism for changing the tilt angle, and changes the tilt angle α of the spotlight main body 23 in accordance with an angle adjustment signal from the operation unit 24. The operation unit 24 is provided on the wall surface of the room 7 and is preferably provided at a position close to the operation unit 22 of the particle group generator 3. Both operation parts 22 and 24 may be provided in the same housing | casing fixed to the wall surface.

  The light source 23a of the spotlight main body 23 may be any one as long as the wavelength of the emitted light 4 is equal to or smaller than the diameter of the particles of the particle group 2, and various types such as an incandescent bulb, an LED, and a fluorescent lamp can be used. Further, even if the wavelength of the light emitted from the light source 23a is not smaller than the particle diameter, a filter is installed on the front surface of the spotlight body 23 so as to convert the wavelength of the light emitted from the light source 23a to be smaller than the particle diameter. It may be. The filter in this case may be a filter in which an optical multilayer film is formed on a light-transmitting substrate such as plastic or glass.

  Specifically, when the particle diameter of the gas substance is 0.05 μm, for example, the luminaire 5 that emits blue light having a wavelength of 0.036 μm can be used, and when the particle diameter is 5 μm, Any lighting fixture 5 that emits visible light can be used.

  The lighting system 1 of the present embodiment is configured as described above. For example, when the user Pa on the tatami floor 9 desires to semi-separate the Japanese room space on the tatami floor 9, the operation unit 24 is provided. The lighting device 5 is turned on with appropriate brightness by operating, and the operation unit 22 is operated to operate the drive pump 21 to discharge the particle group 2 from the particle group generator 3. If it does in this way, the irradiation light 4 from the lighting fixture 5 will be scattered by the particle group 2, and the area | region 6 to which light was irradiated will shine planarly like the curtain of light. By forming the shining region 6, the space on the tatami floor 9 becomes a Japanese-style room that is half cut off from the user Pb or the like on the sofa 11, and the user Pa on the tatami floor 9 feels like being in an open space. You can have a sense of being in a private space while holding

  Further, since the user Pa can change the tilt angle α of the lighting fixture 5 by operating the operation unit 24, the user Pa can change the feeling of opening by arbitrarily moving the glowing region 6 in the vertical direction. For example, the user Pa can move the shining region 6 upward by turning the tilt angle α upward, thereby obtaining a sense of openness. On the contrary, by moving the shining area 6 downward, surrounding the area below the user Pa's line-of-sight height with the shining area 6 makes it possible to enhance the sense of being in an isolated space.

  The ejected particle group 2 is regulated by the regulation plate 18 so that the traveling direction thereof is adjusted, and therefore, the ejected particle group 2 falls into a planar shape having a thickness equivalent to the interval t between the regulation plates 18 and falls downward to shine. Can be prevented from collapsing. Further, since the specific gravity of carbon dioxide gas is heavier than that of air, and the direction in which the particle group 2 falls due to its own weight coincides with the direction in which it discharges, the dissipation of the particle group 2 in the lower position can be suppressed. It is possible to prevent the shape from collapsing.
