上記のように構成された棚照明システム１の動作について説明する。棚２の周辺に人が居るときには、人感センサ５は、その存在を検知して検知信号を制御部４の演算処理部４１に送信する。演算処理部４１は、この検知信号を受信すると、識別用光源２２を発光させるための制御信号を生成する。点灯回路部４２はこの制御信号を受けて、識別用光源２２を点灯制御する。識別用光源２２が点灯することによって、色センサ３は、陳列物１０からの反射光を検知し、検知信号を演算処理部４１に送信する。演算処理部４１は、この検知信号に基づいて、上述のように可変色光源２１を発光させるための制御信号を生成する。点灯回路部４２は前記制御信号を受けて、可変色光源２１を点灯制御する。   Operation | movement of the shelf lighting system 1 comprised as mentioned above is demonstrated. When there is a person around the shelf 2, the human sensor 5 detects the presence and transmits a detection signal to the arithmetic processing unit 41 of the control unit 4. When receiving this detection signal, the arithmetic processing unit 41 generates a control signal for causing the identification light source 22 to emit light. Upon receiving this control signal, the lighting circuit unit 42 controls the lighting of the identification light source 22. When the identification light source 22 is turned on, the color sensor 3 detects reflected light from the display object 10 and transmits a detection signal to the arithmetic processing unit 41. Based on the detection signal, the arithmetic processing unit 41 generates a control signal for causing the variable color light source 21 to emit light as described above. The lighting circuit unit 42 receives the control signal and controls lighting of the variable color light source 21.

棚２の周辺に人が居ないときには、制御部４は、可変色光源２１を予め設定した演出照明用の分光分布で点灯制御する。このような演出照明用の分光分布としては、例えば、棚２の周囲の雰囲気を落ち着かせ、且つ暖かみのある空間を作り出せる低色温度（２８００〜４５００Ｋ）のものが挙げられる。また、このような分光分布を、季節感を演出できるように春夏秋冬に合わせて変化させたり、午後と午前で異なったものとなるように時間帯に応じて変化させたりしてもよい。   When there is no person around the shelf 2, the control unit 4 controls lighting of the variable color light source 21 with a preset spectral distribution for effect lighting. As such a spectral distribution for effect lighting, for example, one having a low color temperature (2800 to 4500 K) that can calm the atmosphere around the shelf 2 and create a warm space can be cited. Further, such a spectral distribution may be changed according to spring, summer, autumn and winter so as to produce a sense of the season, or may be changed according to the time zone so as to be different in the afternoon and morning.

本実施形態に係る棚照明システム１によれば、棚２の周辺に人が居るときには、可変色光源２１による光の分光分布を認識用の分光分布にして、顧客が陳列物１０の色調を正確に認識できるように陳列物１０を照明し、棚２の周辺に人が居ないときには、可変色光源２１による光の分光分布を演出照明用の分光分布にして、人目を引くことができるように陳列物１０を照明するので、視覚的効果の高い演出照明を行うことができる。   According to the shelf lighting system 1 according to the present embodiment, when a person is present around the shelf 2, the spectral distribution of light from the variable color light source 21 is changed to a spectral distribution for recognition, and the customer accurately sets the color tone of the display object 10. When the display 10 is illuminated so that it can be recognized and there is no person around the shelf 2, the spectral distribution of the light from the variable color light source 21 can be changed to a spectral distribution for effect lighting so that it can be noticed. Since the display object 10 is illuminated, it is possible to perform effect lighting with a high visual effect.

（第３の実施形態）
本発明の第３の実施形態に係る棚ユニット照明システムについて図５乃至図８を参照して説明する。棚ユニット照明システム１１は、図５乃至図７に示すように、複数の棚２が組み合わされた棚ユニット６を備えて成るものである。本実施形態において棚ユニット６は、棚２が横方向に５つ、縦方向に４つ組み合わされたものであって、各棚２毎に、上述の光源２０、色センサ３及び制御部４が設けられ、横方向に並んだ棚２の１列毎に、棚ユニット６の周辺に人が存在するか否かを検知する人感センサ５が設けられている。光源２０は、上述の可変色光源２１と識別用光源２２とで構成され、可変色光源２１は、棚２毎に複数配置されていてもよい。 (Third embodiment)
A shelf unit lighting system according to a third embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 5 to 7, the shelf unit lighting system 11 includes a shelf unit 6 in which a plurality of shelves 2 are combined. In the present embodiment, the shelf unit 6 is a combination of five shelves 2 in the horizontal direction and four in the vertical direction, and the light source 20, the color sensor 3, and the control unit 4 described above are provided for each shelf 2. A human sensor 5 that detects whether or not a person is present around the shelf unit 6 is provided for each row of the shelves 2 arranged in the horizontal direction. The light source 20 includes the above-described variable color light source 21 and identification light source 22, and a plurality of variable color light sources 21 may be arranged for each shelf 2.

上記のように構成された棚ユニット照明システム１１の動作について説明する。棚ユニット６の周辺に人が居るときには、人感センサ５は、その存在を検知して検知信号を制御部４の演算処理部４１に送信する。このとき、検知信号は、人感センサ５が設けられた列の棚２にある全ての演算処理部４１に送信される。演算処理部４１は、この検知信号を受信すると、識別用光源２２を発光させるための制御信号を生成する。点灯回路部４２はこの制御信号を受けて、識別用光源２２を点灯制御する。識別用光源２２が点灯することによって、色センサ３は、陳列物１０からの反射光を検知し、検知信号を演算処理部４１に送信する。演算処理部４１は、この検知信号に基づいて、上述のように可変色光源２１を発光させるための制御信号を生成する。点灯回路部４２は前記制御信号を受けて、可変色光源２１を点灯制御する。   Operation | movement of the shelf unit illumination system 11 comprised as mentioned above is demonstrated. When there is a person around the shelf unit 6, the human sensor 5 detects the presence and transmits a detection signal to the arithmetic processing unit 41 of the control unit 4. At this time, the detection signal is transmitted to all the arithmetic processing units 41 in the shelf 2 in the row where the human sensor 5 is provided. When receiving this detection signal, the arithmetic processing unit 41 generates a control signal for causing the identification light source 22 to emit light. Upon receiving this control signal, the lighting circuit unit 42 controls the lighting of the identification light source 22. When the identification light source 22 is turned on, the color sensor 3 detects reflected light from the display object 10 and transmits a detection signal to the arithmetic processing unit 41. Based on the detection signal, the arithmetic processing unit 41 generates a control signal for causing the variable color light source 21 to emit light as described above. The lighting circuit unit 42 receives the control signal and controls lighting of the variable color light source 21.

棚ユニット６の周辺に人が居ないときには、制御部４は、各棚２毎の可変色光源２１をそれぞれにおいて予め設定した演出照明用の分光分布で点灯制御する。このように各棚２毎に個別に異なる発光色にして、棚ユニット６全体の発光態様で演出照明を行うようにする。例えば、図８（ａ）に示すように、棚２の１列毎に可変色光源２１を異なる発光色で発光させ、棚ユニット６全体に任意のデザインが現れるようにする。また、図８（ｂ）に示すように、各棚２毎に可変色光源２１を異なる発光色で発光させ、任意の文字（図中においてはＰの文字）が現れるようにする。   When there is no person around the shelf unit 6, the control unit 4 controls the lighting of the variable color light source 21 for each shelf 2 with a spectral distribution for effect lighting set in advance. In this way, the lighting color is made different for each shelf 2 and the lighting is performed in the light emission mode of the entire shelf unit 6. For example, as shown in FIG. 8A, the variable color light source 21 emits light with a different emission color for each row of the shelf 2 so that an arbitrary design appears on the entire shelf unit 6. Further, as shown in FIG. 8B, the variable color light source 21 is caused to emit light with a different emission color for each shelf 2 so that an arbitrary character (P character in the figure) appears.

本実施形態に係る棚ユニット照明システム１１によれば、棚ユニット６の周辺に人が居るときには、可変色光源２１による光の分光分布を認識用の分光分布にして、陳列物１０の色調を顧客が認識し易いように陳列物１０を照明するので、顧客は陳列物１０を視認すると、陳列物１０の色調や素材感を的確に認識することが可能になる。また、棚ユニット６の周辺に人が居ない場合には、複数の棚２における可変色光源２１による光の分光分布を演出照明用の分光分布にして、明るさや色あいを個別に制御して陳列物１０を照明することで、棚ユニット６にディスプレイ機能や広告機能を付加させることができる。従って、本システムが設置された店舗の存在感を通行人等にアピールし、店舗内への集客力を向上させることが可能になる。また、本システムにおける照明光を店舗空間の主照明として使用し、棚ユニット６の周辺に人が存在するか否かに応じて照明光をオンオフさせることで、店舗照明に必要な電力代を削減することが可能となる。   According to the shelf unit lighting system 11 according to the present embodiment, when a person is present around the shelf unit 6, the color distribution of the light from the variable color light source 21 is changed to a spectral distribution for recognition, and the color tone of the display object 10 is changed to the customer. Since the display object 10 is illuminated so as to be easily recognized, when the customer visually recognizes the display object 10, it becomes possible to accurately recognize the color tone and texture of the display object 10. Further, when there is no person around the shelf unit 6, the spectral distribution of light from the variable color light sources 21 in the plurality of shelves 2 is changed to a spectral distribution for effect lighting, and brightness and color are individually controlled for display. By illuminating the object 10, a display function and an advertisement function can be added to the shelf unit 6. Therefore, the presence of the store where the present system is installed can be appealed to passersby, and the ability to attract customers to the store can be improved. In addition, the illumination light in this system is used as the main lighting of the store space, and the lighting cost is turned on and off according to whether or not there are people around the shelf unit 6, thereby reducing the power cost required for the store lighting. It becomes possible to do.

なお、本発明は、上記各種実施形態の構成に限られず、発明の趣旨を変更しない範囲で種々の変形が可能である。例えば、可変色光源２１にプラスチック製又はガラス製の光拡散板を設けて、陳列物１０を均一に照明できるように構成したものであってもよい。また、棚２を設置した店舗等に人感センサ５を複数配置して、店舗内の人の在否によって、陳列物１０への照明光を切り替えるように構成したものであってもよい。また、可変色光源２１及び識別用光源２２を１つの光源として設けて、制御部４がその１つの光源の発光状態を制御するように構成したものであってもよい。   In addition, this invention is not restricted to the structure of the said various embodiment, A various deformation | transformation is possible in the range which does not change the meaning of invention. For example, the variable color light source 21 may be provided with a plastic or glass light diffusing plate so that the display 10 can be illuminated uniformly. In addition, a plurality of human sensors 5 may be arranged in a store or the like where the shelf 2 is installed, and the illumination light for the display object 10 may be switched depending on the presence or absence of a person in the store. Alternatively, the variable color light source 21 and the identification light source 22 may be provided as one light source, and the control unit 4 may be configured to control the light emission state of the one light source.
