[0002]

2. Description of the Related Art In the human eye, there are cells that work well when bright and cells that work well when dark. When you enter a dark place from a bright place, you will not be able to see anything at first, but you will gradually be able to see the surroundings everyday,
This is because it takes a certain amount of time to adjust the cells that work to adapt to a dark environment, and such adaptation is called dark adaptation.

[0003] On the other hand, when a person suddenly goes out of a dark place to a bright place, the eyes become dazzling due to glare. . The light-dark adaptation as described above varies depending on individuals, but is greatly affected by age, and as the eyes age, the time required for adaptation becomes longer.

In general, the illuminance (unit: lux) is used as a measure of brightness. For example, even if the illuminance due to sunlight or indoor lighting fixtures is doubled, the brightness perceived by us is increased. The feeling is not always doubled. Also, for example, fluorescent lamps include a so-called day white fluorescent lamp and a fluorescent lamp of a light bulb color, but even if the illuminance is the same, depending on the type of the fluorescent lamp, there is a difference in the sense of glare and the like. There is.

[0005]

Conventionally, however, the relationship between the light-dark adaptation and the age, the relationship between the illuminance and the sense of brightness, etc., as described above, are determined by an actual experience based on a menu prepared in advance. Opportunities to learn were scarce.

FIG. 2 shows a state in which only the arrangement of various lighting fixtures on the ceiling 4 is viewed from above, and a plurality of bulb-colored cylindrical fluorescent lamps 10 (above (behind) the acrylic plate 8). The light source) and a plurality of daylight white cylindrical fluorescent lamps 11 (light sources) are alternately mixed and arranged. Each fluorescent lamp 10, 1
1 is connected to a controller (not shown), and the controller controls the amount of light of the fluorescent lamps 10 and 11,
The illuminance in the Japanese-style room 2 can be changed continuously.

As shown in FIG. 3, a front wall 1 of the Japanese-style room 2 is provided.
2, two illuminometers 13 to 15 are provided.
Although not shown, a detection sensor for detecting this outdoor illuminance is provided outdoors, and the detected outdoor illuminance is measured by an illuminometer 1.
3 is displayed. A detection sensor 16 for detecting the illuminance of the wall 11 is installed on the wall 12 in the Japanese-style room 2 so that the illuminance of the wall 12 detected by the detection sensor 16 is displayed on the illuminometer 14. Has become. Further, a detection sensor (not shown) for detecting the illuminance on the floor surface is provided on the floor surface on which the tatami mat 1 is laid, and the illuminance on the floor surface is displayed by the illuminometer 15.

At a position below the illuminometers 13 to 15 on the wall portion 12, there is provided a visual acuity table 18 on which a large number of Randle rings 17 having different sizes are displayed. In addition, the wall 12 is provided with a lighting device 5, 6, a lamp 7, a fluorescent lamp 10, 11 or the like, which is turned on or off, or a light amount when the fluorescent lamps 10, 11 are turned on, that is, 12 or a number of push buttons (not shown) for adjusting the illuminance on the floor
Is provided on the operation panel 19. This Japanese room 2
A standard manual is prepared in advance for experiencing and learning the light-dark adaptation and the relationship between the illuminance and the sense of brightness, and selects the push buttons on the operation panel 19 to sequentially press and operate. By doing so, you can experience and learn along the manual.

In the above configuration, the attendant guides the visitor into the Japanese-style room 2 and closes the sliding door 3, thereby blocking the invasion of light from the outside. In this state, the attendant operates in accordance with the manual. By appropriately operating the panel 19,
Various experiences and learning related to the brightness or its change can be performed. For example, when experiencing light adaptation, the controller reduces the amount of light of the fluorescent lamps 10 and 11 so that the illuminance in the Japanese-style room 2 is set to about 1.5 lux to darken the Japanese-style room 2, and from this state, By rapidly increasing the light amounts of the fluorescent lamps 10 and 11, the illuminance in the Japanese room 2 is rapidly increased to about 1500 lux to brighten the inside of the Japanese room 2.

Thus, the visitor can experience light adaptation. In this case, if a push button corresponding to 1.5 lux and a push button corresponding to 1500 lux are provided in advance on the operation panel 19, the desired illuminance can be obtained only by pressing and operating these push buttons. Obtainable. In order to allow the visitor to experience dark adaptation, on the contrary, the interior of the Japanese-style room 2 is set to a bright state of, for example, about 1500 lux, and the fluorescent lamp 10 is set in this state.
The illuminance in the Japanese-style room 2 may be reduced to about 1.5 lux by making the light amount of the light 11 sharply decrease to make the room dark.

Next, in order for the visitor to experience the relationship between the illuminance and the visual acuity, the light intensity of the fluorescent lamps 10 and 11 is switched to a plurality of levels, so that the illuminance in the Japanese room 2 is changed to a plurality of levels, for example, 100 lux, 500 Lux, 1000 lux,
The relationship between the illuminance and the visual acuity can be known by switching to four stages of 1500 lux and performing an acuity test using the visual acuity table 18 at each illuminance.

As for the relationship between the illuminance and the sense of brightness, for example, the illuminance is sequentially reduced to 1/10 from 1500 lux → 150 lux → 15 lux, and the sense of brightness at that time is sequentially reduced to about 1/10 according to the illuminance. Experience whether it feels like a drop. Usually, even if the illuminance is reduced to 1/10,
The sense of brightness does not always seem to be reduced to 1/10. For example, if the difference in the sense of brightness between 1500 lux and 150 lux is dare converted into a numerical value, the difference in the sense of brightness is usually 10: It feels much smaller than one.

Next, how much brightness is required for various kinds of work performed indoors on a daily basis is determined by Japanese Industrial Standard JIS-Z.
Although it is defined by -9110, it is possible to experience how much brightness is required for various tasks while changing the illuminance in the Japanese-style room 2. For example, the illuminance that does not hinder walking indoors varies depending on individuals and ages, but is usually about 30 to 75 lux. Therefore, the illuminance in the Japanese-style room 2 is set to 3
By setting the brightness to about 0 to 75 lux, the user is allowed to confirm by experience that the brightness does not hinder walking.

The illuminance required for newspaper reading or long-time reading is usually about 500 to 1000 lux. Therefore, the illuminance in the Japanese-style room 2 is set to about 500 to 1000 lux to confirm that the brightness does not hinder reading. Furthermore, the illuminance required for fine visual tasks such as sewing and handicrafts is usually about 750 to 2000 lux. Therefore, the illuminance in the Japanese-style room 2 is adjusted to about 750 to 2,000 lux to confirm that sewing or handicraft is not hindered.

During the various experiences and learning as described above, the illuminance on the wall 12 and the illuminance on the floor in the Japanese-style room 2 are displayed by illuminometers 14 and 15. Fluorescent lamp 1
When illuminating the interior of the Japanese-style room 2 only with 0 and 11, the illuminance of the wall 12 and the floor surface is slightly different, but does not greatly differ. On the other hand, the illuminance outdoors is displayed by the illuminometer 13. Thereby, the illuminance in the Japanese-style room 2 and the illuminance outdoors can be compared.

The illuminance outdoors is, for example, 1000 in fine weather.
It is about 0 lux, about 5000 lux on cloudy days, and about 0.2 lux on a full moon night. On the other hand, the illuminance in the room due to various lighting fixtures is usually about 2000 lux at the maximum, but the illuminance in the Japanese-style room 2 in the present embodiment is a large number of fluorescent lights provided around the ceiling 4 of the Japanese-style room 2. Lamp 1
By maximizing the light amounts of 0 and 11, it is possible to increase the illuminance in the Japanese-style room 2 to about 10000 lux, which is almost equal to the illuminance in fine weather outdoors.

As described above, there are two types of fluorescent lamps: bulb-colored lamps and daylight-colored lamps. In general, many people feel that daylight-white fluorescent lamps are brighter than light-bulb-colored fluorescent lamps. is there. Furthermore, elderly people and the like often feel the daylight fluorescent lamp dazzling. Therefore, when building a house or replacing lighting equipment, it is necessary to select either a bulb-color fluorescent lamp or a neutral white fluorescent lamp in consideration of individual user preferences, family age group, and the like. Is preferred.

Therefore, the fluorescent lamp 1 of the light bulb color is
Instead of lighting the 0 and daylight fluorescent lamps 11 at the same time, only the light bulb fluorescent lamp 10 is turned on to change the light amount appropriately, or only the daylight white fluorescent lamp 11 is turned on to change the light amount appropriately. Accordingly, each visitor can select which of the bulb-color fluorescent lamp 10 and the neutral white fluorescent lamp 11 is preferable for himself.

In the Japanese-style room 2, when various experiences and learning related to the brightness and its change as described above are not performed, or when taking a break during the experience or learning, the fluorescent lamp 10 is used.
11 may be turned off, and the lighting equipment 5 or 6 having a built-in light bulb color or daylight white fluorescent lamp may be turned on. Further, when it is desired to illuminate a local area in the Japanese-style room 2, the desired area may be irradiated with light while adjusting the direction of the lamp 7. In the above-described embodiment, the lighting experience facility is configured using the Japanese-style room 2. However, the lighting experience facility of the present invention uses, for example, a Western-style room and the fluorescent lamps 10 and 11 on the ceiling of the Western-style room. It may be configured by disposing a light source capable of changing the light amount.
