図１に示すように、本発明の実施形態にかかる照明器具１０は、被取付面である天井１１に埋め込まれて、下方の室内を照明するのに使用することができる。
照明器具１０は、天井１１に埋め込まれて取付けられる器具本体２０と、器具本体２０に可動状態で収容される灯具３０と、灯具３０に収容される複数の点光源４０を有する。 As shown in FIG. 1, the lighting fixture 10 concerning embodiment of this invention is embedded in the ceiling 11 which is a to-be-attached surface, and can be used for illuminating the lower room | chamber interior.
The lighting fixture 10 includes a fixture main body 20 that is embedded and attached to the ceiling 11, a lamp 30 that is housed in the fixture main body 20 in a movable state, and a plurality of point light sources 40 that are housed in the lamp 30.

図２にも示すように、器具本体２０は、天井１１に埋め込まれた際に下方に露出するリング形状の鍔部２１を有し、鍔部２１の内側が下方に開口（開口部２１１）している。鍔部２１の裏側（上側）には、灯具３０を可動状態で収容するための灯具収容部２２が形成されている。灯具収容部２２は、一部を切除した球状をしており、内部には灯具３０を収容する灯具収容空間２３が形成されている。灯具収容空間２３は、半球よりやや大きめの部分球状の空間となっている。 As shown also in FIG. 2, the instrument body 20 has a ring-shaped flange 21 that is exposed downward when embedded in the ceiling 11, and the inside of the flange 21 opens downward (opening 211). ing. On the back side (upper side) of the collar portion 21, a lamp housing portion 22 for housing the lamp 30 in a movable state is formed. The lamp housing part 22 has a spherical shape with a part removed, and a lamp housing space 23 for housing the lamp 30 is formed inside. The lamp housing space 23 is a partially spherical space that is slightly larger than the hemisphere.

図２に示すように、灯具３０は、一部を切除した球状の灯具本体３１を有し、一部にはほぼ平面状の照射面３２を有する。灯具３０は、器具本体２０の球状の灯具収容空間２３に可動状態で収容され、器具本体２０の開口部２１１から照射面３２を下方に露出している。
従って、ここでは、可動状態とは、球状の灯具本体３１の中心を中心として、任意の方向へ回転可能な状態を言う。 As shown in FIG. 2, the lamp 30 has a spherical lamp body 31 with a part cut away, and a substantially flat irradiation surface 32 in part. The lamp 30 is housed in a spherical lamp housing space 23 of the fixture body 20 in a movable state, and the irradiation surface 32 is exposed downward from the opening 211 of the fixture body 20.
Therefore, here, the movable state refers to a state in which rotation is possible in an arbitrary direction around the center of the spherical lamp body 31.

灯具本体３１の照射面３２には、点光源４０を収容する複数個の点光源収容部３３が凹設されており、下方に開口（開口部３３１）している。点光源収容部３３は、一部を切除した部分球状をしており、内部に点光源４０を可動状態で収容する。 A plurality of point light source accommodating portions 33 for accommodating the point light sources 40 are recessed in the irradiation surface 32 of the lamp body 31 and open downward (opening portions 331). The point light source accommodating portion 33 has a partially spherical shape with a part removed, and accommodates the point light source 40 in a movable state therein.

図３にも示すように、点光源４０は、一部を切除した球状の点光源本体４１を有し、内部空間４４を有する。内部空間４４には、プリント基板４５が取付けられており、プリント基板４５の前面（下面）には光源であるＬＥＤ４２が実装されている。さらに、ＬＥＤ４２の前方には、所定の形状をした集光レンズ４３が取付けられている。 As shown also in FIG. 3, the point light source 40 has a spherical point light source body 41 with a part removed, and has an internal space 44.

図４（Ａ）に示すように、点光源４０を個別に回転させて、３個の点光源４０によって１個の広い照明範囲を形成することができる。この状態で灯具３０を回転させることにより、照明範囲を所望の方向へ移動させることができる。
また、図４（Ｂ）に示すように、点光源４０を個別に回転させて、小さな３個の照明範囲を形成することができる。この状態で灯具３０を回転させると、３個の照明範囲を保持して、全体の照射方向を変えることができる。 4A and 4B show examples of illumination and light distribution states by the lighting fixture 10.
As shown in FIG. 4A, the point light sources 40 can be individually rotated to form one wide illumination range with the three point light sources 40. By rotating the lamp 30 in this state, the illumination range can be moved in a desired direction.
Further, as shown in FIG. 4B, the point light sources 40 can be individually rotated to form three small illumination ranges. When the lamp 30 is rotated in this state, the entire illumination direction can be changed while maintaining the three illumination ranges.

以上、説明した本発明の照明器具１０の実施形態によれば、点光源４０は、各々独立して灯具３０に対して可動状態で取付けられ、さらに灯具３０は器具本体２０に対して可動状態に取付けられる。このため、点光源４０は、天井１１に埋め込まれて取付けられている器具本体２０に対して、各々独立して向きを変えることができるので、照明範囲および配光状態を自由に変えることができる。 As described above, according to the embodiment of the lighting fixture 10 of the present invention described above, the point light sources 40 are independently attached to the lamp 30 so as to be movable, and the lamp 30 is movable relative to the fixture body 20. Mounted. For this reason, since the point light source 40 can change direction independently with respect to the instrument main body 20 embedded and attached to the ceiling 11, an illumination range and a light distribution state can be changed freely. .

また、点光源４０は、各々前方に集光レンズ４３を有するので、個々の点光源４０によって複数の対象物に対して光を照射することができる。 Moreover, since each point light source 40 has the condensing lens 43 in the front, each point light source 40 can irradiate light with respect to several target object.

なお、本発明の照明器具は、前述した実施形態に限定されるものでなく、適宜な変形，改良等が可能である。
例えば、前述した実施形態においては、点光源４０を３個設けた場合について例示したが、点光源４０の数は任意である。 In addition, the lighting fixture of this invention is not limited to embodiment mentioned above, A suitable deformation | transformation, improvement, etc. are possible.
