JP4654842B2 - Illumination space atmosphere design method and illumination space atmosphere control system - Google Patents

Description

  The present invention relates to an illumination space atmosphere design method and an illumination space atmosphere control system.

  Conventionally, various lighting design methods have been proposed for the purpose of improving the brightness of a room and improving visibility (see, for example, Patent Documents 1 and 2).

  The design of indoor lighting is carried out by some specialists who have expertise in lighting. Here, the lighting design is changed to “appropriate lighting fixtures to satisfy the required brightness and atmosphere in the room”. In the broad sense, “selecting”, it can be considered that a general user's act of selecting a lighting apparatus suitable for his / her room by looking at a catalog or the like is also a part of the lighting design.

  In order to be a guide for lighting design for such general users, in addition to information on lighting fixture output (such as the number of light sources W) and design, etc., lighting manufacturers, for example, ceiling lights for residential lighting In the case of, based on the result of illuminance calculation from the light distribution data of each appliance, specify the size of the room where the horizontal plane illuminance of the JIS illuminance reference level is generally satisfactory, and catalogs with suitable tatami mat number “6-8 tatami” etc. It was written in. Further, in order to convey to the user the atmosphere of the space when the lighting fixture is installed in the room, a method of posting an image photograph or CG image in which the fixture is installed in the model room has been adopted.

Recently, in a highly designed room mainly composed of indirect lighting with multiple lamps in one room and wall lighting, the lighting environment has a “feel of brightness” that suits the purpose of the room, considering the room conditions. There has also been proposed a lighting design method in which a general user who does not have lighting expertise can easily select a lighting fixture that achieves the above and a combination of lighting fixtures.
JP-A-9-320311 JP 2003-151308 A

  The above-mentioned conventional method of displaying the number of tatami mats can only provide information on whether or not the horizontal illuminance when a single lighting fixture is arranged satisfies a specified level, and conventional image photographs and CG images are posted in the catalog. In this method, only the impression and atmosphere of lighting under a specific condition can be transmitted, and the impression and atmosphere of lighting under various room conditions (interior and arrangement of equipment) desired by the user can be transmitted. Not reached.

  In addition, in a highly designed room mainly composed of indirect lighting with multiple lamps in one room and wall lighting, a “brightness” suitable for the purpose of the room should be considered even for general users who do not have lighting expertise. Although the lighting environment could be designed in this way, the user's request regarding the atmosphere of the room such as “I want to make the room calm” and “I want to make the room open” has not been satisfied.

  The present invention has been made in view of the above-mentioned reasons, and its purpose is to suit the atmosphere of the room requested by the user in a highly design room mainly composed of indirect lighting with a plurality of lamps and wall lighting. It is intended to provide a lighting space atmosphere design method and a lighting space atmosphere control system in which a general user who does not have lighting expertise can easily realize a combination of a lighting device and a lighting device that realizes a lighting environment.

  According to the first aspect of the present invention, a color chart in which the luminance of the surface is changed using a light source different from the light source of the lighting fixture that illuminates the room is provided in the room, and the color chart viewed from the occupants is in the room. The color mode boundary luminance is the luminance of the color chart when an unnatural color looks like an intermediate level between the luminance level recognized as a placed object and the luminance level recognized as a light source that emits light. Classify multiple lighting fixtures that illuminate the room into categories by irradiation area within the field of view of the occupants, and the ratio of each color mode boundary luminance when the lighting fixtures for each category illuminate the room, or The ratio of each brightness sensation unit set as a unit for evaluating the brightness of each category of lighting fixtures based on the boundary brightness of each color mode of each category of lighting fixtures is determined to achieve a desired atmosphere in the room. Set to ratio It is characterized in.

  According to the present invention, even a general user who does not have illumination expertise can easily obtain a desired atmosphere in a space based on the color mode boundary luminance or brightness unit value of each lighting fixture described in a catalog or the like. A luminaire and a combination of luminaires to be realized can be selected. In other words, in a highly designed room mainly composed of indirect lighting with multiple lamps in one room and wall lighting, a combination of lighting fixtures and lighting fixtures that realize a lighting environment that matches the atmosphere of the room requested by the user, It can be easily realized by general users who do not have specialized knowledge.

  The invention of claim 2 classifies the category according to the irradiation area in the field of view of the occupant into three categories, that is, a position where the irradiation position is high, a low position, and an intermediate position between a high position and a low position. It is characterized by that.

  According to the present invention, design can be simplified by classifying into categories that are easily understood by the user.

  According to a third aspect of the present invention, in the first or second aspect, the predetermined ratio of each color mode boundary luminance for each category or the predetermined ratio of each brightness sensation unit for each category for realizing a desired atmosphere. It is characterized by different depending on the use of the room.

  According to this invention, the range of application of this design method can be expanded.

  According to a fourth aspect of the present invention, in any one of the first to third aspects, the ratio of each color mode boundary luminance for each category, or the ratio of each brightness sensation unit for each category, the room atmosphere is a desired atmosphere. As described above, the predetermined ratio is set in advance.

  According to the present invention, it is possible to improve the convenience of the user who wants to realize a desired atmosphere, and to realize energy saving by realizing the desired atmosphere with as little power consumption as possible.

  According to a fifth aspect of the present invention, in any one of the first to third aspects, the ratio of each color mode boundary luminance for each category, or for each category, by increasing or decreasing the output of some of the plurality of lighting fixtures. The ratio of each brightness sense unit is changed, and the atmosphere of the room is continuously changed from the first atmosphere to the second atmosphere.

  According to the present invention, the range of atmospheres applicable to the space can be expanded, and the value of the space used by the user can be improved.

  The invention of claim 6 comprises a plurality of lighting fixtures for illuminating the room, and a control means for controlling the output of each lighting fixture using the atmosphere design method for the lighting space according to any one of claims 1 to 5. And

  According to the present invention, it is possible to provide an atmosphere control system for an illumination space that can achieve the same effects as any one of the first to fifth aspects.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
In recent years, the number of users who are particular about indoor interiors has increased, and as a result, indoor lighting is not a method of placing a single ceiling light on the ceiling, but lighting fixtures and variations in their placement. However, various methods have been adopted, and many lighting methods using a combination of multiple lamps in one room have been seen. FIG. 5 shows an example of a single room multiple lamp arrangement in a residential room. In this example, three lighting fixtures La10 to La12 having different irradiation areas are arranged in the room.

  Therefore, in such a lighting method with multiple lamps in a room, each lighting fixture is classified (categorized) according to the position within the field of view of the occupant according to the irradiation area, and the lighting fixtures for each category Each “brightness” set as a unit for evaluating the brightness of each category of lighting fixtures based on the ratio of each “color mode boundary luminance” when lighting or the color mode boundary luminance of the lighting fixtures of each category An experiment was conducted focusing on the influence of the change in the ratio of “feeling unit” on the atmosphere of the space.

  First, in the present invention, as a method of quantitatively grasping the “brightness sensation unit”, measurement of color mode boundary luminance in the concept of illumination recognition visual space (Reference 1: measurement of brightness size of illumination recognition visual space) Using the evaluation of the brightness of the space in the real environment, Journal of the Illuminating Science Society of Japan, Vol. 86, No. 11, 2002, P830-836, Yamaguchi et al.) As a light source (light source color) that emits light by itself as a level of brightness recognized as an object (object color) placed in the room. By measuring the brightness level (this is called “color mode boundary brightness”), which is in the middle of the perceived brightness level, and looks like an unnatural color for an object placed in the room The brightness of the illuminated room The those expressed quantitatively.

  It has also been shown that color mode boundary luminance additivity holds in non-uniform lighting environments (Reference 2: Additivity of spatial brightness in non-uniform lighting environments, 36th National Congress of the Illuminating Society of Japan) Proceedings, P154, 2003, Yamaguchi et al.) When a certain lighting environment Z1 is the sum of the lighting environments Z2 and Z3, the color in the lighting environment Z1 is the sum of the color mode boundary luminances in the lighting environments Z2 and Z3. It has been demonstrated that mode boundary luminance can be predicted.

  From the above, by measuring the “color mode boundary luminance” in the concept of illumination-recognition visual space, it is possible to quantitatively grasp the sense of brightness of the space, and specify the sense of brightness of the room where a certain luminaire is installed It can be said that it is technically possible to set the “brightness unit”.

  Here, the test patch luminance presentation device 1 shown in FIG. 6 is used for the color mode boundary luminance setting which is the method of the present invention. The test patch luminance presentation device 1 includes a light source box 1a that houses a light source system 1b configured by a slide projector using a halogen light bulb as a light source, and an optical system box that houses a rotational density filter 1d. 1c, a movable flat mirror 1e, and a test patch T provided at a height of 1100 mm from the installation plate 1a by a support 1f. The test patch T is locally illuminated by the light passing through the rotational density filter 1d from the light source system 1b reflected by the movable plane mirror 1e. The subject can freely adjust the brightness of the test patch T by rotating the rotational density filter 1d with a switch at hand. Further, the test patch T is inclined at an angle of 45 ° downward so that the test patch T is hardly affected by illumination. The test patch T has a size of 60 mm × 60 mm, and the irradiated surface is made of N5 and gray paper.

  From the “color mode boundary luminance” set as described above, a “brightness unit” is derived based on the following [Equation 1], and the unit is referred to as “Feu”.

  Next, a plan view of the experimental facility is shown in FIG. 7, and a perspective view is shown in FIG. An 8 tatami real size residential room Ra having a room size: 3500 mm × 3500 mm and a ceiling height: 2500 mm was used for the experiment. The ceiling and walls have a white cloth finish, the wall is partitioned with a white roll screen 2, and the floor has a slightly glossy dark brown flooring with the roll screen 2 facing to the right. The approximate center on the Ra1 side is the observation position P of the subject.

  The lighting equipment to be used is one whose irradiation area is a high position (category high) in the field of view of the occupant (category high), a low position (category low), or an intermediate position between a high position and a low position ( (Category Middle)). Then, as the lighting fixture LH1 belonging to the category High, an upper light for a Dycool bulb 65W × 3 lamps is disposed at a position 600 mm × 600 mm from the left corner of the subject side wall surface Ra1, and the ceiling is irradiated. Further, as a lighting fixture LM1 belonging to the category “Middle”, a fluorescent light 40W × 1 vertical light is arranged at a position 250 mm × 250 mm from the right corner of the wall surface Ra2 where the subject faces from the observation position P, and the intermediate height of the wall surface Ra2 Irradiate the vicinity. Further, as a lighting fixture LL1 belonging to the category Low, a horizont of a fluorescent lamp 40W × 1 lamp is arranged at a position 100 mm from the left corner of the wall surface Ra2 that the subject faces from the observation position P to irradiate the vicinity of the floor surface of the wall surface Ra2. In this way, by classifying the luminaire categories according to the position of the irradiation area, the classification criteria can be intuitively understood by the user, and the design can be simplified. In addition, each of these lighting fixtures LH1, LM1, and LL1 can be dimmed by the dimmer 3 arranged at the hand of the subject.

  First, prior to this experiment, the “color mode boundary” when each of the lighting fixtures LH1, LM1, and LL1 is turned on and measured by installing the test patch luminance presentation device 1 so that the test patch T is located 2500 mm from the wall surface Ra1. The relationship between “luminance” and “floor center illuminance” measured by the illuminometer 4 installed in the center of the floor of the room was determined. As an example, FIG. 9 shows the relationship between the color mode boundary luminance of the lighting fixture LH1 and the floor surface central illumination. A straight line Y in FIG. 9 is a straight line (y = 0.0.1085x + 1.1681) obtained by linear regression for all plot points, and its determination coefficient is 0.983, which is a very high value. Similarly, the relationship between “color mode boundary luminance” and “floor center illumination” of the lighting fixtures LM1 and LL1 is also represented by a straight line. Therefore, it can be said that the relationship between the “color mode boundary luminance” and the “floor center illumination” of each of the lighting fixtures LH1, LM1, and LL1 is linearly proportional. Then, by monitoring the floor surface central illuminance while dimming each of the lighting fixtures LH1, LM1, LL1, based on the relationship between these “color mode boundary luminance” and “floor surface central illuminance”, each category High, The “color mode boundary luminance” of Middle and Low, or the “brightness unit” calculated using [Equation 1] can be adjusted to an arbitrary value.

Next, the procedure and results of the experiment are described. As subjects, 10 men and women engaged in lighting-related work in their 20s to 30s with normal vision and color vision were selected. Each subject is presented with a total of 12 combinations of “Brightness Sensation Units” (scene 1 to scene 12) shown in FIG. The instrument LL1 was dimmed according to the following instructions.
“Assuming you are relaxing without doing anything in your home, adjust the dimming to the best light balance.”
“Next, stop where it feels strange to make it darker than this.”
“Next, stop where you feel uncomfortable if you brighten more than this.
“Once again, adjust the dimming for the best lighting balance.”
The subjects entered and exited for each condition, and the presentation order of each condition was a random order for each subject.

  As a result of the above experiment, “Brightness sensation unit” of category Low shown in FIG. 10 shows the average value of the dimming result for all the subjects in the scenes 1 to 12 with respect to the lighting fixture LL1, and the best lighting in each condition The atmosphere of the space when balanced is "relaxed (not relaxed-relaxed)", "feeling calm (not calm-calmed down)", "feeling peaceful (no relaxation-relaxed)", "bright FIG. 11 to FIG. 13 show graphs of subject average values obtained by 7-level evaluations for “feel (dark-bright)”, “open feeling (narrow-wide)”, and “preferability (dislike-like)”. .

  A discussion of the above results is given below. First, each graph of FIGS. 11 to 13 shows that the atmosphere of the space changes for each scene with different conditions. Each evaluation result regarding “feeling of opening” and “feeling of brightness” shown in FIGS. 11 (a) and 11 (b) shows almost the same tendency, and each of the lighting fixtures LH 1, LM 1, and LL 1 of all categories. The evaluation of “feeling of openness” and “feeling of brightness” increases as the sum of “feeling of brightness” increases, that is, the brightness of the entire space increases.

  Next, looking at the evaluation results regarding “feeling of relaxation”, “feeling of calmness”, and “feeling of peace” shown in FIGS. 12A, 12B, and 12C, the same tendency is shown. The evaluation of the scenes 10, 11, and 12 with relatively high overall “brightness” is low. However, even in a scene in which the sum of “brightness sensation units” of all categories High, Middle, and Low is the same, evaluation is performed between conditions in which the ratios of “brightness sensation units” of categories High, Middle, and Low are different. (For example, scene 2 and scene 4, scene 5 and scene 7).

  As described above, according to the illumination area of the luminaire installed in the room, the irradiation area is a high position in the field of view of the occupant, a low position, or between the high position and the low position. The position is classified into three categories, and the ratio of “brightness unit” based on “color mode boundary luminance” for each category affects the atmosphere in the illuminated room. Furthermore, it was found that the indoor atmosphere can be controlled by changing the ratio of “brightness sensation unit” for each category.

  In the atmosphere evaluation experiment based on the difference in the ratio of each “brightness sensation unit” of the lighting fixture LH1, the lighting fixture LM1, and the lighting fixture LL1 arranged in the 8 tatami residential room Ra, the use of the room is not particularly specified. Since the experiment was conducted assuming that the room is a general living room, it was necessary to check what results would be obtained when the usage of the room was specified. Therefore, we conducted an atmosphere evaluation experiment based on the difference in the “brightness sensation unit” ratio for each category in the Japanese-style house as described below.

  Fig. 14 shows the experimental facilities in a Japanese-style house. An 8-tatami Japanese-style room Rb provided with an Rb1 between the floors is used, a desk 5 is disposed in the approximate center, and a position where the desk 5 is sandwiched facing the wall surface Rb2 provided with the Rb1 between the floors is defined as an observation position P of the subject.

  The lighting fixtures to be used are classified into three categories High, Middle, and Low according to the irradiation area as described above. Then, a Japanese paper indirect pendant is placed on the ceiling surface at the center of the room as the lighting fixture LH2 belonging to the category High. In addition, Japanese style downlights are arranged at the four corners of the room as the luminaire LM2 belonging to the category Middle, and spotlights for the floor are arranged so as to irradiate the center of the wall surface of the Rb1 between the floors as the luminaire LM3 belonging to the category Middle. In addition, as a lighting fixture LL2 belonging to category Low, only the lamps of a Japanese style stand are placed at one corner on the floor, and as a lighting fixture LL3 belonging to category Low, a milky white glass globe stand is placed at the corner opposite to lighting fixture LL2. Deploy. Each of these lighting fixtures LH2, LM2, LM3, LL2, and LL3 can also be dimmed. In addition, the external appearance of lighting fixture LH2, LM2, LM3, LL2, LL3 is shown to Fig.15 (a)-(e).

Next, the procedure and results of the experiment are described. As subjects, 10 men and women engaged in lighting-related work in their 20s to 30s with normal vision and color vision were selected. Then, similarly to the experiment in the residential room Ra shown in FIG. 7, the relationship between the color mode boundary luminance and the floor center illuminance of each lighting fixture LH2, LM2, LM3, LL2, LL3 alone is obtained. By monitoring the floor surface illuminance while dimming LH2, LM2, LM3, LL2, and LL3, each category High, Middle is monitored based on the relationship between these “color mode boundary luminance” and “floor center illuminance”. , “Color mode boundary luminance” or “Brightness unit” for each Low can be adjusted to an arbitrary value. Based on the experimental results in the residential room Ra shown in FIG. 7 above, each subject has a combination condition (scenes 11 to 11) of all nine categories of “High / Middle” categories shown in FIG. Scene 19) was presented, and lighting fixtures LL2 and LL3 belonging to category Low were dimmed according to the following instructions under each condition.
“Assuming you are relaxing without doing anything in your home, adjust the dimming to the best light balance.”
“Next, stop where it feels strange to make it darker than this.”
“Next, stop where you feel uncomfortable if you brighten more than this.
“Once again, adjust the dimming for the best lighting balance.”
The subjects entered and exited for each condition, and the presentation order of each condition was a random order for each subject.

  As a result of the above experiment, “Brightness sensation unit” of category Low in FIG. 16 shows an average value of dimming results for all subjects under category Low in each condition, and the atmosphere of the space is expressed as “relaxation” and “settlement”. 17 (a) to 17 (c) show graphs of subject average values obtained by 7-level evaluation for “feel” and “feeling of peace”. Comparing the evaluation results in the Japanese-style room Rb shown in FIGS. 17A to 17C with the evaluation results in the residential room Ra shown in FIGS. 12A to 12C, “relaxation” and “relaxation” In the Japanese room Rb, the ratio of the scene 18 (category High, Middle, Low) is higher than the condition of the scene 4 (category High, Middle, Low ratio is 2: 1: 4), which was the highest in the residential room Ra. Is higher in the condition of 2: 2: 2).

  In this way, when the usage of a room is specified, even if the desired atmosphere is the same, the ratio of the brightness sensation unit for each category that realizes the atmosphere may differ depending on the usage of the room. Has been suggested.

  Next, the evaluation result of “feeling of opening” and “feeling of brightness” in the residential room Ra shown in FIGS. 11A and 11B and the evaluation result of “preference” in the residential room Ra shown in FIG. Pay attention. First, although the sum of the “brightness sensation units” of each category High, Middle, and Low, that is, the feeling of openness and “brightness sensation” increases as the overall brightness of the space increases, From the viewpoint of “preference”, if the sum of “brightness units” is large, the evaluation of “preference” is not necessarily high. Also, from the viewpoint of energy saving, it is not desirable to increase the “brightness sensation unit” indiscriminately because it increases power consumption related to illumination. Therefore, the ratio of the “brightness sensation unit” for each category High, Middle, Low that is optimal for providing the atmosphere of “open feeling” and “brightness sensation” is 2: 4: 4 (scene 6). Or it can be said that it is 4: 2: 4 (scene 8).

  Thus, from the above evaluation results, the ratio of “brightness unit” for each category High, Middle, and Low that is optimal for making the atmosphere of the space a desired atmosphere can be found, so that the optimum atmosphere for the desired atmosphere can be obtained. By setting the ratio of “brightness sensation unit” in advance, it is possible to improve the convenience of the user who wants to achieve the desired atmosphere and to achieve energy saving by realizing the desired atmosphere with as little power consumption as possible. it can.

  Next, evaluation results of “feeling of relaxation”, “feeling of calm” and “feeling of peace” in the residential room Ra shown in FIGS. 12A, 12B and 12C, and the houses shown in FIGS. 11A and 11B. Attention is paid to the evaluation results of “feeling of opening” and “feeling of brightness” in the room Ra. First, as described above, the ratio of “brightness sensation units” for each category High, Middle, and Low that is optimal for the space to have an atmosphere of “open feeling” and “brightness sensation” is 2: 4: 4 (scene 6) or 4: 2: 4 (scene 8). Then, by reducing the “brightness sensation unit” of the category Middle of the scene 6 from 4 to 1, or by reducing the “brightness sensation unit” of the category High of the scene 8 from 4 to 2, “relaxation” Therefore, it is possible to realize the conditions of the scene 4 or the scene 5 that have a high evaluation of “feeling of calmness” and “feeling of peace”. That is, even if the types and arrangements of the lighting fixtures are the same, the indoor atmosphere can be greatly changed by changing the outputs of some of the lighting fixtures.

  Based on the above experimental results, an atmosphere design method for an illumination space according to the present embodiment will be described below.

FIG. 3 shows the “brightness sensation units” for all lighting fixtures La1 to La8 with different irradiation areas. The lighting fixtures La1 to La4 are 2 (Feu), and the lighting fixtures La5 to La8 are 4 (Feu). And when there are three categories according to the irradiation area in the field of view of the resident, High, Middle, and Low, as described above,
FIG. 4 shows the ratio of “brightness sensation units” for each category High, Middle, and Low for realizing the desired atmosphere (“feeling of calm”, “feeling of opening”) of the residential room and the Japanese-style room. Then, in order to realize the user's favorite atmosphere according to the room, the user satisfies the ratio of “brightness unit” for each category High, Middle, and Low shown in FIG. Select a lighting fixture. For example, when it is desired to obtain “feeling of calm” in a normal 8-tatami residential room Ra, as shown in FIG. 1, a lighting fixture La1 (when fully lit: 2 (Feu)) is arranged as a lighting fixture LH10 belonging to the category High. The lighting fixture La2 (when fully lit: 2 (Feu)) is placed as the lighting fixture LM10 belonging to the category Middle, and the lighting fixture La8 (when fully lit: 4 (Feu)) is placed as the lighting fixture LL10 belonging to the category Low. Thus, the ratio of “brightness sensation unit” for each of the categories High, Middle, and Low is set to 2: 2: 4.

  In addition, when it is desired to obtain “a feeling of openness” in an ordinary 8-tatami residential room Ra, as shown in FIG. 2, a lighting fixture La6 (when fully lit: 4 (Feu)) is arranged as a lighting fixture LH11 belonging to the category High. The lighting fixture La7 (when fully lit: 4 (Feu)) is placed as the lighting fixture LM11 belonging to the category Middle, and the lighting fixture La8 (when fully lit: 4 (Feu)) is placed as the lighting fixture LL11 belonging to the category Low. As a result, the ratio of “brightness sensation unit” for each category High, Middle, and Low is set to 4: 4: 4.

  In this way, by setting the ratio of “brightness sensation unit” for each category High, Middle, and Low according to the atmosphere of the room to be realized, even a general user who does not have lighting expertise can easily catalog. The combination of the lighting fixture and the lighting fixture that realizes a desired atmosphere in the space can be selected based on the value of the color mode boundary luminance or the brightness unit of each lighting fixture. That is, a general user who does not have expertise in lighting can easily realize a combination of a lighting fixture and a lighting fixture that realizes a lighting environment that matches the atmosphere of the room desired by the user.

  Next, when it is desired to obtain a “feeling of calm” in the Japanese room Rb of Article 8, the ratio of “brightness sensation unit” for each category High, Middle, and Low is set to 2: 2: 2 as shown in FIG. Select a lighting fixture and a combination of lighting fixtures to set, and if you want to get "open feeling", set the ratio of "brightness feeling unit" for each category High, Middle, Low to 4: 4: 4 It is only necessary to select a lighting fixture and a combination of lighting fixtures, and the ratio of “brightness unit” for each category High, Middle, Low is set according to the room usage of the residential room Ra, the Japanese-style room Rb, etc. Thus, the range of application of the present design method can be expanded.

  In this embodiment, the ratio of “brightness unit” for each category High, Middle, and Low is set. However, the ratio of “color mode boundary luminance” for each category High, Middle, and Low is set in the room. Even if it is set according to the application, the desired atmosphere of the room can be similarly realized.

(Embodiment 2)
FIG. 18 shows the configuration of the atmosphere control system of the illumination space. As in the first embodiment, the categories according to the irradiation area in the field of view of the resident are High, Middle, and Low, and the three categories are High, Middle, The lighting fixtures LH11, LM11, and LL11 corresponding to Low, the dimming unit 6 that changes each output of the lighting fixtures LH11, LM11, and LL11, and any “brightness unit” of the lighting fixtures LH11, LM11, and LL11 A storage unit 7 for storing a corresponding dimming signal is arranged in an 8-tatami residential room Ra.

  Here, a dimming signal corresponding to the ratio of “brightness sensation unit” for each category High, Middle, Low is stored in advance in the storage unit 7 in order to realize a desired atmosphere. The dimming signal corresponding to is transmitted from the dimming unit 6 to the lighting fixtures LH11, LM11, and LL11, and the lighting fixtures LH11, LM11, and LL11 are dimmed and controlled to a ratio of “brightness unit” that provides a desired atmosphere. As such, it is set in advance. In this way, by setting in advance so as to achieve the desired atmosphere, the convenience of the user who wants to achieve the desired atmosphere is improved, and the desired atmosphere is realized with as little power consumption as possible to save energy. Can be planned.

(Embodiment 3)
The atmosphere control system of this embodiment is shown in FIG. 18 as in the second embodiment. In the present embodiment, the dimming signal corresponding to the ratio of “brightness sensation unit” for each category High, Middle, and Low for realizing the atmosphere A in the storage unit 7 and each for realizing the atmosphere B are stored in the storage unit 7. The dimming signal corresponding to the ratio of “brightness sensation unit” for each of the categories High, Middle, and Low is stored, and transmitted from the dimming unit 6 to the lighting fixtures LH11, LM11, and LL11 using a switch (not shown). By switching the light control signal to either one, the atmosphere of the room is continuously changed from atmosphere A to atmosphere B or from atmosphere B to atmosphere A. By changing the atmosphere of the room in this way, the range of the atmosphere applicable to the space can be expanded, and the value of the space used by the user can be improved.
