Description

  The present invention relates to a blind that takes in external light from a window and a lighting control system that controls illuminance by linking the blind and the lighting device in order to reduce power consumption of the lighting device.

Conventionally, Venetian blinds, vertical blinds made of aluminum light-shielding slats, and light-shielding blinds such as cloth roll blinds have been generally used as blinds attached to windows.
Among these, for example, the Venetian blind made of the shading slats can adjust the slat angle appropriately to brighten the room while preventing the glare of sunlight, and darken the room by closing the shading slats in the vertical direction. It is a blind that is useful even when using a projector or the like.

On the other hand, we installed an illuminator with automatic illuminance control function (a dimmable illuminator or illumination system with a function to control the total illuminance of the external light combined with the illumination light from the illuminator). In order to reduce the power consumption of the lighting device with automatic illuminance control function by adopting outside light, adjust the angle of the light shielding slats as appropriate during the day so as not to dazzle and as much outside light as possible. Must be adopted. However, it is cumbersome to adjust the angle of the shading slats according to the movement of the sun, taking into account the balance between dazzling and daylighting, so it is usually kept closed to prevent sun glare. There are many. Therefore, the reduction in power consumption of the lighting device with the automatic illuminance control function is limited, and the current situation is that the automatic illuminance control function in the previous period has not been effectively utilized.

On the other hand, a semi-transparent member having a light diffusing function is used as a light diffusing slat, and even if the light diffusing slat is completely closed, a daylighting blind capable of taking in outside light while suppressing glare is invented. Has been devised. (Patent Document 1, Patent Document 2, Patent Document 3, Patent Document 4)
By installing the daylighting blind at the window, outside light reaches the back of the room, and power consumption can be effectively reduced even with the lighting device with automatic illumination control function installed at the wall away from the window. It becomes like this. In addition, since the outside light can be taken in even when the light diffusing slat is completely closed, it is not necessary to adjust the angle of the light diffusing slat, and when combined with an illumination device with an automatic illumination control function, the power consumption of the illumination It becomes an effective blind in reduction.
In addition, an illumination control system has been invented in which an electric blind that automatically adjusts the angle of the light-shielding slat and a dimmable illumination device are linked to obtain appropriate illuminance. (Patent Document 5)
By using such an illumination control system, it is possible to reduce the power consumption of the illumination automatically without any troublesome manpower.

However, when the daylighting blinds of Patent Documents 1 to 4 are installed, the heat rays of sunlight are also diffused into the room, so that the temperature of the room rises and the power consumption of the lighting device decreases, but the power consumption of the air conditioner The negative effect of increasing will occur. In the case of a roll blind made of a light diffusing sheet, since air does not permeate, it is necessary to wind it up in ventilation, but it is troublesome to periodically lift and lower the plurality of roll blinds.
Furthermore, when it is desired to darken the room, such as when using a projector, not only can the room be darkened even if the light diffusion slats are completely closed, but the diffused light reaches the projection screen placed on the wall and is projected. This causes a bad effect that it becomes difficult to see the image.
Further, Patent Document 5 in which a blind and a lighting device cooperate with each other transmits a slat open / closed state to a lighting device from a centralized control device of the blind that automatically controls opening and closing according to the state of external light, and from the information, the illuminance on the lighting device side It is a lighting control system that corrects a target value, and it can reduce the power consumption of the lighting device, but requires an initial investment.

  Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1)
FIG. 1 is an example of a Venetian blind in which the slat of the present invention is used. The slat 2 is supported in a suspended manner by a plurality of stages by the lifting / lowering cord 6 and the slat angle adjusting cord 7, and the brightness of the room is adjusted by adjusting the inclination angle of the slat 2 and lifting / lowering. FIG. 2 shows an example of a roll blind, which adjusts the brightness of a room by moving the screen fixed at one end to the winding rod 8 by rotating the winding rod.

FIG. 3 shows an enlarged cross section of the heat ray shielding light diffusing sheet which is a member of the slat and the screen of the first embodiment. The heat ray shielding light diffusing sheet is cut into a desired size to produce a slat or a screen. The heat ray shielding light diffusion sheet of the present invention includes a base material 12, a light diffusion layer 13 provided on one side of the base material 12, and a heat ray shielding layer 16 provided on the back surface thereof.
In the light diffusion layer 13, light diffusing particles 14 having a size capable of Mie scattering or geometric optical scattering of visible light are fixed to the base material 12 with a resin 15, and the vicinity of the top of the particles 14 is exposed to the air interface side and is fine. It has a structure in which various protrusions are formed. The uneven surface diffuses the emitted light as indicated by the arrows, so that the glare is softened and the outside light reaches the four sides of the room.
The heat ray shielding layer 16 has a structure in which heat ray shielding particles 17 having such a size that visible light is not scattered by Mie scattering and geometric optical scattering are dispersed in the resin 15 by substantially primary particles. Since visible light is not scattered and is emitted in a state where only heat rays are shielded, the total light transmittance and cloudiness (haze) can be adjusted by the structure of the light diffusion layer.

  FIG. 4 is an enlarged cross section of a heat ray shielding light diffusing sheet having a structure in which a heat ray shielding layer 16 is formed on one surface of a substrate and a light diffusion layer is laminated on the surface of the heat ray shielding layer 16. It is a structure and shows the same heat ray shielding light diffusibility.

  As the substrate 12, for example, a translucent plastic film can be used. As the translucent plastic film, known polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, polyvinyl chloride, polyamide, polyimide, triacetyl cellulose, polyethylene, polypropylene, polystyrene, polycarbonate, polyacrylate, polymethyl methacrylate, etc. A polymer film is mentioned. Among these, considering the mechanical strength of the film, a substrate having a thickness suitable for slats and screens is appropriately selected. If necessary, a plastic film containing a flame retardant, an ultraviolet absorber, a plasticizer, or the like is used.

The light diffusing particles 14 are preferably translucent and have a particle size that allows visible light to undergo Mie scattering or geometric optical scattering. For example, acrylic particles, methacrylic particles, styrene particles having a particle size of 1 μm or more, It is preferable to use known resin particles such as acrylic styrene copolymer particles and benzoguanamine particles, and inorganic particles such as silicon dioxide, titanium dioxide, zinc oxide and alumina. In particular, it is more preferable to use resin particles having a small refractive index difference between the resin and the particles because the total light transmittance can be increased and the light can be easily taken into a room. Further, when the particle diameter is 1 μm or less, the light scattering property is lowered, so that it is necessary to devise such as agglomerating particles to form fine protrusions.

As the heat ray shielding particles 17, hexaboride such as lanthanum hexaboride having a particle diameter of 200 nm or less that does not generate Mie scattering and geometric optical scattering, and high visible light transmittance and heat ray shielding rate, tungsten oxide, antimony -It is preferable to use the particle | grains which consist of metal oxides, such as a tin oxide (ATO), an indium tin oxide (ITO), and a titanium oxide. In order to prevent the occurrence of Rayleigh scattering, it is particularly preferable to use ultrafine particles having a particle diameter of several nanometers to several tens of nanometers.

The resin 15 can be appropriately selected from known electron beam curable resins, ultraviolet curable resins, thermosetting resins and the like in consideration of mechanical properties. In the case where the light diffusion layer 13 is located on the outermost surface of the slat or roll, it is preferable to have a pencil hardness of 2H or higher after the curing treatment. This makes it possible to obtain slats and screens that are difficult to scratch.

  The light diffusing layer 13 and the heat ray shielding layer 16 are prepared by adding the respective particles 14 and 17 and the resin 15 and, if necessary, a dispersant and mixing and dispersing in a solvent to prepare a paint, followed by wet coating, drying, It is formed through a curing process. In addition, it is more preferable to use a low-viscosity ultraviolet curable resin and to form a solvent-free paint, so that the light diffusion layer and the heat ray shielding layer can be formed in a process with a small environmental load. Further, the heat ray shielding layer may be formed by dry coating such as sputtering with a material for shielding each heat ray.

  The total light transmittance and haze can be adjusted by the contents of the resin 15 and the particles 14 in the light diffusion layer 13 and the average thickness of the coating film, and a light diffusion sheet having desired optical characteristics can be created. By making the volume content of the resin in the coating film smaller than the volume content of the particles, the vicinity of the top of the particles is easily exposed to the air interface, which is preferable. In particular, by setting the resin volume content to half or less of the particle volume content, hemispherical protrusions can be formed, and light can be diffused at a wide angle, which is more preferable.
