常に狭い等の欠点があった。[Prior art] Conventionally, when a dimmer using an electrochromic (hereinafter referred to as EC) is applied to a display system of an exhibit, a variation range of transmittance is about 10 to 75%, As long as the light of the light source used is constant, it is impossible to increase the width of the contrast beyond the range of the transmittance. Therefore, when it is desired to make the exhibit invisible, even if the transmittance of the dimmer is reduced while the light source is turned on, the exhibit is not completely invisible. Further, when adjusting the contrast of an exhibit to enhance the effect of the exhibit or to give a change to the exhibit, there is a disadvantage that the adjustment range is extremely narrow.

において調光体１にECタイプのものを使用しており、EC
調光体の透過率は一般に75〜10％の範囲で変更でき、ま
た蛍光灯２の照度は100〜０％の範囲で適宜変えられ
る。The operation of the present invention will be described using examples. However, the operation of the present invention is not limited to the embodiment. Example 1
Uses an EC type dimmer 1
Generally, the transmittance of the dimmer can be changed in the range of 75 to 10%, and the illuminance of the fluorescent lamp 2 can be changed as appropriate in the range of 100 to 0%.
初めに調光体１の透過率75％、蛍光灯２の照度100％
と透過率と照度を連動させることによってあるいは独立
して制御することによって、調光体１の透過率10％の時

により、背景画３の明暗のコントラストが調光体１単体
あるいは蛍光体２単体の場合に比較して格段に向上す
る。First, the transmittance of the dimmer 1 is 75% and the illuminance of the fluorescent lamp 2 is 100%
By interlocking or independently controlling the transmittance and the illuminance, the fluorescent light 2 is displayed at 0% illuminance when the transmittance of the dimmer 1 is 10%, so that the background image 3 Is significantly improved as compared with the case where the dimmer 1 or the phosphor 2 is used alone.
調光体１の透過率が高い状態では、背景画３は前方か
ら入射する外光の影響を大きく受けることになり、調光
体１の透過率が低い状態では、背景画３は展示装置上部
の蛍光灯２から斜めに照射される光の影響を大きく受け

るようなコントラストが得られ、調光体１の透過率が低
い状態では、斜め上方からの蛍光体２による光のみであ
るようなコントラストが得られ、そのコントラストが変
化して見た目が変化する。In the state where the transmittance of the light control body 1 is high, the background image 3 is greatly affected by external light incident from the front, and in the state where the transmittance of the light control body 1 is low, the background image 3 is located above the display device. Of the fluorescent lamp 2 is obliquely irradiated. For this reason, when the transmittance of the light control body 1 is high, contrast is obtained as if the background image 3 is illuminated obliquely from above and from the front, and when the transmittance of the light control body 1 is low, the contrast is obliquely upward. Thus, a contrast such that only the light from the phosphor 2 is obtained is obtained, and the contrast changes to change the appearance.
これに上記に加えて、調光体１の透過率が高い状態

しくは段階的に双方を繰り返しても良い。In addition to the above, if the illuminance of the fluorescent lamp 2 is reduced in a state where the transmittance of the light control body 1 is high, external light from the front becomes strong, and a normal light contrast of a photograph can be obtained. further,
If the transmittance of the dimmer 1 is set to be low and the illuminance of the fluorescent lamp 2 is also reduced, even if the external light is considerably strong, the display object becomes dark and hard to see. By independently controlling the three dimmers 1, the appearance is further changed. The timing of controlling the dimmer 1 and the fluorescent lamp 2 is arbitrary. First, the transmittance of the dimmer 1 is reduced or increased, and then the illuminance of the fluorescent lamp 2 is made darker or brighter, or stepwise. May be repeated.

示品の存在を著しく強調する効果がある。FIG. 2 shows another embodiment of the present invention, wherein 21 is an EC dimmer, 22 is a fluorescent lamp, and 23 is an exhibit. When the transmittance of the EC dimmer 21 is 10% and the fluorescent lamp 22 is turned off (illuminance 0%), the exhibit 23 cannot be seen from the outside, and the transmittance of the EC dimmer 21 is 75%.
% And the fluorescent light illuminance of 100%, the exhibit 23 is clearly visible, and the display of the EC dimmer 21 is visible by repeating the interlocking adjustment within the range of 75 to 10% and the illuminance of 100 to 0%. The contrast difference is remarkable and has the effect of remarkably enhancing the presence of the exhibit.

る。In addition, if you bring the lighting inside this exhibition device behind, if the lighting is brightened and the transmittance of the EC dimmer is high, it will be like a cloudy day in the picture where the entire light is shining Contrast is obtained. In addition, when the transmittance of the EC dimmer is low, a backlight contrast of a photograph can be obtained.
In addition, if the illumination inside the display device is reduced while the transmittance of the EC dimmer is high, external light from the front becomes stronger, and the contrast of the photograph in the forward direction can be obtained. Furthermore, if the transmittance of the EC dimmer is low and the lighting inside the exhibition equipment is also reduced,
Even if the external light is very strong, the display will be dark and difficult to see.

It has a remarkable contrast point, has an excellent effect such that the transmittance of the light control body is minimized and the illuminance of the light source is set to zero, thereby making the display completely invisible, and the illuminance of the light source is gradually reduced to 0%. As compared with the case where the illuminance is changed from 100% to 0% instantaneously, it is natural, and also has an effect of giving the viewer a favorable feeling as a lighting effect.
