Description

  The present invention relates to a lighting system.

  As a residential lighting system, for example, there is a daylighting device that takes light outside a building (direct light or skylight) into a living room. This daylighting device is installed near the opening of a building window or the like to ensure the brightness of the room. If this daylighting device is used, it is said that a lot of skylight can be taken in without increasing the opening of the building.

  However, the above daylighting apparatus has the following problems. In other words, since the daylighting device is affected by the direction and altitude of the sun, when the daylighting device is installed in the opening of a house with a narrow interval between adjacent buildings, which is often seen in urban areas, the light passes through the opening. However, there was a problem that sufficient effects could not be obtained.

  In order to solve such a problem, the present inventors have found that the brightness of the living room can be improved by providing a lighting device in the above-described daylighting apparatus. As a lighting fixture, for example, a lighting fixture independent of a door or a sliding door, as described in Patent Document 1 below, is installed on the entrance roof or the like, and the entrance door or the entrance floor is used as lighting around the entrance of the building. Those that illuminate are known. According to the configuration found by the present inventors (the configuration in which the lighting device of Patent Document 1 below is provided in the daylighting device installed in the opening), the daylighting device is installed in the opening of the adjacent house. The problem can be solved to some extent.

Also, the position of the north side of the east side of the outer peripheral wall adjacent to the neighboring H _N housing H, the opening W is provided. The opening W is, for example, a relatively small window such as a vertical window. The illumination system 100 is installed in the opening W, and is used for putting light into a living room through the opening W. In the case of urban areas, the distance between the adjacent ridges between the house H and the neighbor H _N is narrow, and direct light or sky light cannot be expected from the opening W facing the neighbor H _N. In some cases, the brightness of the room may be insufficient if the light is reflected and the light is taken into the room through the opening W. In this case, the illumination system 100 shown in this embodiment is required. As is clear from the figure, although sufficient light can be taken in through the opening W _S not facing the neighbor H _N , the light taken in through the opening W _S is The light does not reach the area on the north side (upper side in FIG. 1) of the room of the house H. Thus, even outdoor light L _S as it is possible Komu taken through the opening W _S of the housing H, when the brightness of the partial region of the room is insufficient, in this embodiment It is particularly effective to provide the illumination system 100 as an auxiliary.

  FIG. 2 shows a schematic configuration of the illumination system 100 shown in FIG. The lighting system 100 is for taking light into a living room through an opening W provided on an outer wall Wa of a building. The lighting system 10, the illumination light source 20, the sensor 30, the blind 40, and a control device 90.

  The eaves unit 10 is provided on the upper side of the opening W, and protrudes on the outdoor side and is attached to the outer wall Wa of the building. The jar unit 10 is provided with an illumination light source 20. In FIG. 2, the illuminating unit 10 is provided with the illumination light source 20. However, the present invention is not limited to this, and the illuminating unit 10 is not provided with the illuminating light source 20. It is also possible to attach the illumination light source 20 to the outer wall Wa.

  The illumination light source 20 emits light when it is energized, and includes a light source that emits light L having directivity in a specific direction (the direction of the opening W in the present embodiment). In this embodiment, for example, an LED is provided as a light source having directivity, and one or a plurality of LEDs are provided so as to obtain a necessary illuminance. Control of energization to the illumination light source 20 is performed by the control device 90. When the illuminating light source 20 emits light, the light L from the illuminating light source 20 is introduced from the eaves unit 10 through the glass surface of the opening W into the living room as shown in FIG. Note that the illumination light source 20 is not limited to the LED, and various LEDs can be selected as long as the illumination light source 20 has a function of emitting light having directivity toward the opening. Moreover, although illustration is abbreviate | omitted, the solar cell (illustration omitted) and the battery (illustration abbreviation) which store the electric power which generate | occur | produced with the solar cell and the electric power which generate | occur | produced with the said solar cell are provided in the saddle unit 10, The light emission amount of 20 may be adjusted.

  The sensor 30 is a detection device that is provided in a living room of a building and has a function of measuring the light condition of the living room. Specifically, the sensor 30 is preferably a luminance sensor that can measure the brightness of the opening W and the brightness of the outer peripheral wall Wa (particularly the surface Waa on the living room side), but it is irradiated per unit area. It is also possible to use an illuminance sensor capable of measuring the luminous flux (illuminance). The sensor 30 is electrically connected to the control device 90, and measurement data measured by the sensor 30 (data relating to light in the room, for example, information relating to luminance and illuminance) is transmitted to the control device 90 as needed. As will be described later, the control device 90 controls the color temperature and light flux of the light from the illumination light source 20 based on the value measured by the sensor 30.

The blind 40 lowers the wall surface brightness (in other words, the brightness when the opening W is viewed from the room of the house H) of the neighbor (the neighbor H _{N in} FIG. 1), and the indoor side wall near the opening W looks dark. It is a member for reducing the phenomenon. The blind 40 is attached to, for example, the front end portion of the eaves unit 10 so as to block the light that is reflected on the wall surface of the neighboring house and enters the living room through the opening W of the house H (see FIG. 1). The blind 40 may be a light that is reflected on the wall surface of the neighboring house and that completely blocks light directed toward the opening W of the house H. However, the blind 40 has a predetermined gap such as a surface lattice and is completely blocked. It may not be. In addition, the blind 40 may have a function of changing the size of a predetermined gap of the surface lattice, for example, so that it can be adjusted depending on whether the light is completely blocked or not completely blocked. In this embodiment, the blind 40 is provided in the eaves unit 10, but is not limited to this. The blind 40 is disposed between the house H and the neighbor H _N and has a function of reducing the wall brightness of the neighbor H _N. If it has, it is possible to install in the required location of the house H suitably.

  The control device 90 is a so-called microcomputer, and includes a CPU, a ROM, a RAM, an input / output interface, and the like. The control device 90 is electrically connected to the illumination light source 20, the sensor 30, the blind 40, and the like. By controlling these operations, the control device 90 can control the color temperature and illuminance of light introduced to the living room side through the opening W, and can adjust the light distribution to the living room. Yes. For example, the control device 90 can control the color temperature and illuminance from the illumination light source 20 according to measurement data measured by the sensor 30 (luminance sensor or illuminance sensor).

  Moreover, the control apparatus 90 can also control the color temperature and illuminance from the illumination light source 20 according to time as follows. In the present embodiment, the control device 90 has a function as a measuring unit (timer) for measuring time, and controls the color temperature and illuminance from the illumination light source 20 according to the time zone measured by the timer. The device 90 can be adjusted and the frequency of visible light entering the room can be controlled. By controlling the frequency of visible light according to the time zone, not only can the light of a more natural impression be taken into the room, but also assistance for morning awakening, etc., and the rhythm of the resident can be adjusted be able to. Note that a timer for measuring time may be separately provided instead of mounting a measuring unit for measuring time in the control device 90.

  As a method of adjusting the color temperature according to the above-described time zone, for example, the control device 90 controls the color temperature of the light emitted from the illumination light source 20 according to the morning time zone, the noon time zone, and the evening time zone. Is preferred. In general, the color temperature of sunlight is low in the morning time zone (for example, about 4500 K to 5000 K), and the color temperature of sunlight is high in the day time zone (for example, about 6000 to 6500 K), and the evening time zone. Since the color temperature of sunlight is medium (for example, 5000 to 5500 K), when the time zone measured by the timer is, for example, the morning time zone, the control device 90 controls the illumination light source 20. It is preferable to increase the color temperature. Further, when the time zone measured by the timer is, for example, a daytime zone, it is preferable that the control device 90 controls the illumination light source 20 to lower the color temperature.

  In this way, the color temperature of light from the illumination light source 20 can be maintained in an optimum state according to the time zone. As a result of being able to control the color temperature of the light from the illumination light source 20 according to the time zone separately from the situation of the room, for example, in the morning time zone when the color temperature is relatively low, the color temperature is increased, The brightness can be adjusted.

  2 shows an example in which the control device 90 is provided as a separate body from the bag unit 10, for example, the control device 90 can be configured to be incorporated in the bag unit 10, and the arrangement thereof can be selected as appropriate. Is possible.

  As described above, in the illumination system 100 according to the present embodiment, the illumination light source 20 is disposed on the eaves unit 10 protruding outside the opening W, and light having directivity from the illumination light source 20 toward the opening W is provided. To emit. Such an illumination light source 20 can increase the amount of light traveling to the living room through the opening W as compared with the case where the lighting unit 10 is provided with illumination intended only for lighting. As a result, the amount of light taken into the living room through the opening W facing the neighboring house, even in an urban house where the distance between neighboring buildings is narrow, where direct light or skylight cannot be expected The darkness of the living room can be reduced.

  The lighting system 100 according to the present embodiment also has the following effects. As has been widely used in the past, there is a known configuration in which the lighting of the living room is turned on for the purpose of improving the brightness of the living room, but in this case, the light from a place different from the opening is used. Therefore, unless consideration is given to the adaptation of the eyes, the brightness becomes insufficient and there is a risk of discomfort. On the other hand, in the illumination system 100 according to the present embodiment, since light is introduced into the room through the opening W to reduce the darkness of the room, light from the same direction as natural light (sunlight) can be introduced. it can. As a result, it is possible to balance the brightness of the living room, and it is also effective from the viewpoint of eye function and psychological viewpoint.

  In the present embodiment, the amount of light in the room including the brightness of the opening W and the brightness of the wall Waa on the room side is measured by the sensor 30, and the color of light emitted from the illumination light source 20 based on the measurement data. Control temperature and strength. Thereby, since the light according to the light environment of a living room can be taken in into a living room via the opening part W, the light distribution to a living room is controlled and the light suitable for the light environment of a living room can be taken in. .

Moreover, in this embodiment, the blind 40 for reducing the brightness | luminance of the surface of the opening part W is provided. By this blind 40, it is possible to block a predetermined amount of light directed toward the opening W of the wall surface reflection to housing H of the neighboring H _N. In the case where this blind is not provided (conventional example), as shown in FIG. 3 (B), the brightness of the opening surface is high when viewed from the living room. As shown in (A), the luminance of the opening surface can be prevented from being excessively increased, and the illumination light source 20 replenishes the living room with light that does not easily affect the luminance of the opening W. , Can balance the brightness of the living room.

  The embodiments of the present invention have been described above with reference to specific examples. However, the present invention is not limited to these specific examples. In other words, those specific examples that have been appropriately modified by those skilled in the art are also included in the scope of the present invention as long as they have the characteristics of the present invention. Each element included in each of the specific examples described above and their arrangement, material, condition, shape, size, and the like are not limited to those illustrated, and can be appropriately changed.
