　制御部ＣＯＮＴは、光源部１００の点灯時において少なくとも可視光（赤色光、緑色光及び青色光）を含む光が被照射部に照射されるように光源部１００を制御する。具体的には、可視光及び赤外光の両方が照射される第一モード、及び、可視光のみが照射される第二モード、を切り替えて光源部１００に行わせる。 The control unit CONT controls the light source unit 100 so that the irradiated unit is irradiated with light including at least visible light (red light, green light, and blue light) when the light source unit 100 is turned on. Specifically, the light source unit 100 is switched between a first mode in which both visible light and infrared light are irradiated and a second mode in which only visible light is irradiated.
　図１に戻って、調整部２００は、被照射部に照射される光の照射範囲を調整する。調整部２００は、光を分割して射出する複数のレンズエレメント４１が形成されたフライアイレンズ（光調整層）４０を有する。フライアイレンズ４０は、光源部１００から被照射部へ向けた光進行方向に沿って、例えば２つ設けられている（４０Ａ及び４０Ｂ）。２つのフライアイレンズ４０Ａ及び４０Ｂは、それぞれ光進行方向の正方向及び逆方向に移動可能に設けられている。制御部ＣＯＮＴは、この２つのフライアイレンズ４０Ａ及び４０Ｂの位置を調整可能である。 Referring back to FIG. 1, the adjustment unit 200 adjusts the irradiation range of the light irradiated to the irradiated portion. The adjustment unit 200 includes a fly-eye lens (light adjustment layer) 40 in which a plurality of lens elements 41 that divide and emit light are formed. For example, two fly-eye lenses 40 are provided along the light traveling direction from the light source unit 100 toward the irradiated portion (40A and 40B). The two fly- eye lenses 40A and 40B are provided so as to be movable in the forward direction and the reverse direction of the light traveling direction, respectively. The control unit CONT can adjust the positions of the two fly- eye lenses 40A and 40B.
　上記のように構成された照明装置ＬＧＴを用いる場合、使用者は、上記の第一モード及び第二モードのいずれを行うかを選択する。制御部ＣＯＮＴは、使用者の選択に応じて、対応するモードを光源部１００に行わせる。 When using the illumination device LGT configured as described above, the user selects which of the first mode and the second mode is performed. The control unit CONT causes the light source unit 100 to perform a corresponding mode according to the user's selection.
　第一モードを行わせる場合、制御部ＣＯＮＴは、光源部１００のうち赤色発光素子２２Ｒ、緑色発光素子２２Ｇ、青色発光素子２２Ｂ及び赤外発光素子２２Ｉのそれぞれから光を射出させるようにする。第一モードが行われる場合、赤色光、緑色光及び青色光の可視光に加え、赤外光が照射される。 When the first mode is performed, the control unit CONT emits light from each of the red light emitting element 22R, the green light emitting element 22G, the blue light emitting element 22B, and the infrared light emitting element 22I in the light source unit 100. When the first mode is performed, infrared light is irradiated in addition to visible light of red light, green light, and blue light.
　被験者に赤外光を含む照明光を照射する場合、この赤外光を含まない照明光を照射する場合に比べて、この被験者は、照明光に対して優しい感覚を感じる傾向にあることを本発明者らは見出した。本実施形態では、第一モードを行わせる場合、赤外光を含む照明光が照明装置ＬＧＴから照射されるため、使用者に対して優しい感覚を感じさせることができる。このように、使用者の感覚に適合する光が照明装置ＬＧＴから照明されることになる。 When irradiating a subject with illumination light including infrared light, the subject tends to feel a gentle sensation with respect to the illumination light as compared with irradiating illumination light not including infrared light. The inventors have found. In this embodiment, when performing 1st mode, since illumination light containing infrared light is irradiated from the illuminating device LGT, a user can feel a gentle feeling. In this way, light that matches the user's sense is illuminated from the illumination device LGT.
　また、第二モードを行わせる場合、制御部ＣＯＮＴは、光源部１００のうち赤色発光素子２２Ｒ、緑色発光素子２２Ｇ及び青色発光素子２２Ｂのそれぞれから光を射出させるようにする。第二モードを行う場合、赤外発光素子２２Ｉを用いないため、消費電力を低減できる。 Further, when the second mode is performed, the control unit CONT emits light from each of the red light emitting element 22R, the green light emitting element 22G, and the blue light emitting element 22B in the light source unit 100. When the second mode is performed, the power consumption can be reduced because the infrared light emitting element 22I is not used.
　制御部ＣＯＮＴは、２つのフライアイレンズ４０Ａ及び４０Ｂの間隔を調整することにより、照明光の照射範囲を広くしたり狭くしたりすることができる。この照明光の照射範囲については、使用者の設定に応じて、あるいは、自動的に制御することにより、調整することができる。 The control unit CONT can widen or narrow the illumination light irradiation range by adjusting the distance between the two fly- eye lenses 40A and 40B. The illumination light irradiation range can be adjusted according to the user's setting or automatically controlled.
　以上のように、本実施形態に係る照明装置ＬＧＴは、被照射部に光を照射する照明装置であって、可視光を発する赤色発光素子２２Ｒ、緑色発光素子２２Ｇ、青色発光素子２２Ｂ及び赤外光を発する赤外発光素子２２Ｉを有する光源部１００と、点灯時において少なくとも可視光を含む光が被照射部に照射されるように光源部１００を制御する制御部ＣＯＮＴとを備えるので、赤外光を含む照明光を照明装置ＬＧＴから照射することができる。
　これにより、使用者に対して優しい感覚を感じさせることができるような、使用者の感覚に適合する光を照明することができる。 As described above, the illumination device LGT according to the present embodiment is an illumination device that irradiates light to an irradiated portion, and includes a red light emitting element 22R, a green light emitting element 22G, a blue light emitting element 22B, and an infrared ray that emit visible light. Since the light source unit 100 having the infrared light emitting element 22I that emits light and the control unit CONT that controls the light source unit 100 so that the irradiated portion is irradiated with light including at least visible light at the time of lighting are provided. Illumination light including light can be emitted from the illumination device LGT.
Thereby, the light suitable for a user's sense which can make a user feel a gentle sense can be illuminated.

For example, in the above embodiment, the package unit 21 of the light source unit 100 is formed in a rectangular shape in plan view, and four light emitting elements are arranged in the package unit 21, and the package unit 21 is arranged in a matrix.

In this case, the arrangement of the lens elements 41 in the fly- eye lenses 40A and 40B can be, for example, an arrangement in which four boundary portions of the lens element 41 overlap with one light emitting element.
　また、図６に示すように、パッケージ部２１を全体的に円形に形成しても構わない。この場合、発光素子の配置、フライアイレンズ４０Ａ及び４０Ｂにおけるレンズエレメント４１の配置については図５と同様ハニカム構造とすることができる。また、これらの配置については、ハニカム構造に限られず、マトリクス状に配置された構造とすることもできる。なお、図５及び図６では、ケース３００の図示を省略している。 Further, as shown in FIG. 6, the package part 21 may be formed in a circular shape as a whole. In this case, the arrangement of the light emitting elements and the arrangement of the lens elements 41 in the fly- eye lenses 40A and 40B can be a honeycomb structure as in FIG. Further, these arrangements are not limited to the honeycomb structure, but may be a structure arranged in a matrix. 5 and 6, the case 300 is not shown.
　また、上記実施形態では、調整部２００の構成として、フライアイレンズ４０が２つ設けられた構成（フライアイレンズ４０Ａ及び４０Ｂが照明光の照射方向に並んで配置された構成）を例に挙げて説明したが、これに限られることは無い。このフライアイレンズ４０が、例えば１つ若しくは３つ以上設けられた構成であっても構わない。 In the above embodiment, the configuration of the adjustment unit 200 is exemplified by a configuration in which two fly-eye lenses 40 are provided (a configuration in which the fly- eye lenses 40A and 40B are arranged side by side in the illumination light irradiation direction). However, it is not limited to this. For example, one or three or more fly eye lenses 40 may be provided.
