Accordingly, the elevating state of the first reflecting plate 182a from the first reflecting plate accommodating groove 181H and the elevating state of the second reflecting plate 182b from the second reflecting plate receiving groove 182H are adjusted.

The lifting control unit 191 is provided in at least two or more so as to correspond to the number of divisions of the reflective plate lifting portions 182A to 182F and to be installed in each portion.

Furthermore, if the first reflecting plate 182a and the second reflecting plate 182b are moved upward as much as possible through the elevation control unit 191, the specific reflecting plate elevation part 182F shown in FIGS. 1 and 3 is below the reflecting plate elevation part 182F. Because no reflector 182 does not come down, the lighting function by the light output to the outside through the anti-glare sheet 170 is provided as it is.

In addition, when the first reflecting plate 182a and the second reflecting plate 182b are moved downward as much as possible through the elevation control unit 191, the reflecting plate elevation part 182A like the specific reflection plate elevation part 182A shown in FIGS. 1 and 3 is below. As a result, the first reflecting plate 182a and the second reflecting plate 182b both come down and block most of the light output to the outside through the anti-glare sheet 170, so that the light is illuminated in a certain area of the side where the corresponding reflecting plate lifting part 182A is located. hardly ever provided.

The unit 192 continuously senses the presence of a person P having a movement within its detection area, and through this, the elevation control unit 191 detects a movement within the detection area from the motion sensor unit 192 connected to each other. In this case, at least one of the first reflecting plate 182a and the second reflecting plate 182b is moved downward to block some or most of the light output to the outside through the anti-glare sheet 170, thereby reducing the level of lighting restrictions through reflection of light will be regulated

Specifically, as shown in FIG. 4, when the motion sensor unit 192 installed in the lifting portion 182A of a specific reflector detects the presence of a person P in its sensing area, the lifting control unit connected to the corresponding motion sensor unit 192 191 moves at least one of the first reflecting plate 182a and the second reflecting plate 182b received and installed in the specific reflecting plate elevating portion 182A to move down the specific reflecting plate elevating portion 182A in the illumination area T. Area on the side is made the lighting limiting area DT so that light is limitedly provided only to the side where the person stands, and the remaining area becomes the lighting providing area LT.

Furthermore, when the separation distance of the objects P1 and P2 for which the motion calculated through the motion sensor unit 192 is sensed falls within the preset first separation distance reference range, the elevation control unit 191 is a first elevator plate The first reflecting plate 182a is moved downward from the receiving groove 181H.

At the same time, the lifting control unit 191 sets the second separation distance reference range in which the separation distance of the objects P1 and P2 for which the motion is detected, calculated through the motion sensor unit 192 is shorter than the upper first separation distance reference range. If it corresponds to, the first reflecting plate 182a is moved down from the first elevating plate accommodating groove 181H, and then the second reflecting plate 182b is moved down from the second elevating plate accommodating groove 182H.

In other words, when the separation distance is long, the lighting restriction is performed using only the first reflection plate 182a, and when the separation distance is close, the lighting restriction is performed using both the first reflection plate 182a and the second reflection plate 182b. will do

Specifically, as shown in FIG. 5, the separation distance of the person P1 sensed by the motion sensor unit 192 installed in the lifting portion 182A of the specific reflector is a motion sensor unit installed in the lifting portion 182C of the other reflector ( 192) is far compared to the distance of the person P2 sensed, so only the first reflecting plate 182a is lowered so that only the light directed to the side is reflected among the light output to the outside through the anti-glare sheet 170 In the lighting area T, a specific area on the side of the reflecting plate lifting portion 182A is made into the lighting partial limiting area DT1.

In addition, as shown in FIG. 5, the separation distance of the person P2 sensed by the motion sensor unit 192 installed in the lifting part 182C of the other reflector is a motion sensor unit 192 installed in the lifting part 182A of the other reflector as shown in FIG. ) is closer than the distance of the detected person P1, so both the first reflecting plate 182a and the second reflecting plate 182b are lowered to reflect the entire light output to the outside through the anti-glare sheet 170. In the lighting area T, the area on the side of the elevating portion 182C of the other specific reflector is made the entire lighting limiting area DT2.
