Description

本発明は、照明装置に関するものであり、特に、被照明物を載置して、載置された被照明物を照らす装飾照明装置に関するものである。   The present invention relates to an illumination device, and more particularly, to a decorative illumination device that places an object to be illuminated and illuminates the object to be illuminated.

従来、この種の照明装置としては、コースターの透明な本体内に電源と発光源（本願発明における光源に該当する）と電気回路を設け、コースターに乗せられるコップ等に光を当てるものが知られている（例えば、特許文献１参照。）。そして、このようなコースターでは、発光源が発する光を反射板等で上方に反射させ、上方に置かれるコップ等に多くの光を当てるように構成されている。また、前記コースターの上面には、コップ等が置かれる部分に凹部が形成されている。
実用新案登録第３０６４１０４号公報 Conventionally, as this type of lighting apparatus, a power source, a light source (corresponding to the light source in the present invention) and an electric circuit are provided in a transparent body of a coaster, and light is applied to a cup or the like placed on the coaster. (For example, refer to Patent Document 1). Such a coaster is configured to reflect light emitted from a light emitting source upward by a reflecting plate or the like, and to apply a lot of light to a cup or the like placed above. Further, a concave portion is formed on the upper surface of the coaster in a portion where a cup or the like is placed.
Utility Model Registration No. 3064104

しかしながら、このような装飾照明用の照明装置においては、透光性を有する部分に光学的に不連続となる部分が形成されているため、透光性を有する部分から発散する光に斑が生じるという問題があった。また、上部にコップ等の被照明物を一つだけ載せることができる小型のコースターであれば問題とならないが、被照明物を複数載せられる大型の照明装置の場合、前述したようなコースターをそのまま拡大した構造を採用すると、使用者が把持し難いため、移動させにくくなってしまうという問題がある。この問題を解決するために、照明装置を把持するための凹部や凸部を形成すると、光学的に不連続な或いは断続した部分が生ずるため、この場合も、透光性を有する部分から発散する光に斑が生じるという問題があった。   However, in such a lighting device for decorative illumination, since a portion that is optically discontinuous is formed in the portion having translucency, spots are generated in light emitted from the portion having translucency. There was a problem. In addition, there is no problem if it is a small coaster that can place only one object such as a cup on the top, but in the case of a large illuminator that can place a plurality of objects to be illuminated, the coaster as described above is used as it is. When an enlarged structure is adopted, there is a problem that it is difficult for the user to move because it is difficult to grip. In order to solve this problem, when a concave portion or a convex portion for gripping the lighting device is formed, an optically discontinuous or intermittent portion is generated. In this case, too, light is emitted from a portion having translucency. There was a problem of spots in the light.

It is configured. In addition, "continuous" said here does not mean that it is connected without breaking, but means that the plane portion 10 (plane) and the curved portion 11 (curved surface) are mathematically continuous, In short, it means that the flat surface portion 10 and the curved surface portion 11 are smoothly connected. In the state of use as shown in FIG. 2, the planar portion 10 is formed to be slightly lower than the outer edge of the top plate 8 and extends from the planar portion 10 to the outer edge of the top plate 8. The curved surface portion 11 is formed so as to be higher toward the outer side. Further, as described above, since the surface of the flat surface portion 10 and the surface of the curved surface portion 11 of the top plate 8 are continuously formed, the optical characteristics, that is, light refraction and reflection are controlled by the flat surface portion 10. The curved surface portion 11 does not change suddenly at the boundary, and gradually changes from the flat surface portion 10 to the curved surface portion 11. The top plate 8 has a maximum weight that can be placed (that is, a weight at which the amount of deformation of the flat portion 10 becomes an allowable limit when the top plate 8 is placed on the flat portion 10).

The light emitting unit 5 includes a second housing 12, a secondary battery 13 provided inside the second housing 12, and a high output as a light source provided above the second housing 12. A light emitting diode 14 of a type, and a switch operation unit 15 and power receiving terminals 16 and 17 provided on the lower surface of the second housing 12 are configured. A concave reflecting portion 18 is formed on the upper surface of the second housing 12 so as to face the light emitting diode 14. The reflecting portion 18 is integrally formed with the second housing 12 by white synthetic resin. Further, the gap between the switch operation unit 15 and the second housing 12 is watertight. The light emitting diode 16 is attached to the lower surface of the heat radiating body 19 made of an aluminum alloy or the like in a state of being electrically insulated from the heat radiating body 19 and in a heat transfer manner. An annular recess 20 is formed on the lower surface of the second housing 12, and the power receiving terminal 17 is provided in the recess 20. Note that the gap between the power receiving terminal 17 and the second housing 12 is watertight by packing or the like (not shown). A mounting hole 21 is formed in the center of the lower surface of the second housing 12, and the power receiving terminal 16 is provided in the mounting hole 21. The gap between the power receiving terminal 16 and the mounting hole 21 is watertight by the packing 22. Further, the recess 20 provided with the power receiving terminal 17 and the power receiving terminal 16 are formed concentrically.

前記充電台３の上面には、前記凹部２０に対応して環状の給電端子２３が設けられている。なお、この給電端子２３で囲まれた領域の中央には、前記受電端子１６に対応して図示しない給電端子が形成されている。   An annular power supply terminal 23 is provided on the upper surface of the charging stand 3 so as to correspond to the recess 20. A power supply terminal (not shown) is formed in the center of the region surrounded by the power supply terminal 23 corresponding to the power receiving terminal 16.

次に、本実施形態の作用について説明する。まず、使用者は、前記充電台３に前記照明装置２を設置することで、この照明装置２の発光ユニット５に収容された前記二次電池１３を予め充電しておく。この際、前記充電台３の上面に設けられた環状の前記給電端子２３が前記照明装置２の発光ユニット５の底面に形成された環状の凹部２０に入り込むことで、前記充電台３に対して前記照明装置２が位置決めされる。そして、このように前記照明装置２が前記充電台３に対して位置決めされることで、前記充電台３に設けられた図示しない給電端子は、前記照明装置２の発光ユニット５の底面に設けられた前記受電端子１６に対して確実に当接する。また、前記給電端子２３は、前記凹部２０内に設けられた前記受電端子１７に対して確実に当接する。この状態で前記照明装置２に電力が供給されることで、図示しない充電回路によって前記二次電池１３が充電される。   Next, the operation of this embodiment will be described. First, the user installs the lighting device 2 on the charging stand 3 to charge the secondary battery 13 accommodated in the light emitting unit 5 of the lighting device 2 in advance. At this time, the annular power supply terminal 23 provided on the upper surface of the charging base 3 enters the annular recess 20 formed on the bottom surface of the light emitting unit 5 of the lighting device 2, so that the charging base 3 is The lighting device 2 is positioned. And the electric power supply terminal which is provided in the said charging stand 3 is provided in the bottom face of the light emission unit 5 of the said illuminating device 2 by positioning the said illuminating device 2 with respect to the said charging stand 3 in this way. Further, the power receiving terminal 16 is surely contacted. In addition, the power supply terminal 23 reliably contacts the power receiving terminal 17 provided in the recess 20. By supplying electric power to the lighting device 2 in this state, the secondary battery 13 is charged by a charging circuit (not shown).

そして、このように前記二次電池１３が充電された照明装置２を使用する場合、まず使用者は、前記照明装置２を前記充電台３から持ち上げて取り外す。この際、前記照明装置２の天板８の曲面部１０に親指を当てると共に、深皿状に形成された前記下筐体７に他の指を当てるようにすれば、把持部が形成されていない本実施形態の構造であっても把持しやすい。そして、使用者は、前記スイッチ操作部１５を操作して前記発光ダイオード１４を点灯させた後、把持した前記照明装置２を平坦な任意の場所に設置する。この際、前記支持部９が平坦な設置面に当接する。また、前述したように、前記照明装置２が防水型であることから、前記照明装置２は水等で濡れる虞のある場所に設置することができる。そして、このようにして任意の平坦な設置面に設置された前記照明装置２は、前記発光ダイオード１４が発した光によって周囲を照らす。即ち、前記発光ダイオード１４が発した光は、前記反射部１８や下筐体７や天板８等で反射した後、半透明な合成樹脂によって成形された前記下筐体７及び天板８を透過して前記照明装置２外に放射され、この放射された光によって前記照明装置２の周囲が照らされる。なお、前記下筐体７及び天板８が半透明な合成樹脂によって成形されていることによって、光が前記下筐体７及び天板８を透過する際に散乱し、これによって、前記照明装置２から放射される光は、いわゆる柔らかい光となる。また、前述したように、前記下筐体７が半透明な合成樹脂によって成形されていることで、前記照明装置２から放射された光によって設置面上を照らすことができる。更に、前記天板８が前記平面部１０と曲面部１１とで構成されているものの、これら平面部１０の面と曲面部１１の面とが連続して形成されているので、光学的な特性、即ち光の屈折や反射が、前記平面部１０と曲面部１１の境界で唐突に変化することがなく、前記平面部１０から曲面部１１にかけて緩やかに変化し、これによって、前記天板８を通過した光にできる斑を少なくすることができ、美観を良好にすることができる。   And when using the illuminating device 2 with which the said secondary battery 13 was charged in this way, a user lifts the said illuminating device 2 from the said charging stand 3, and removes it first. At this time, if a thumb is applied to the curved surface portion 10 of the top plate 8 of the lighting device 2 and another finger is applied to the lower housing 7 formed in a deep dish shape, a grip portion is formed. Even if the structure of this embodiment is not present, it is easy to grip. The user operates the switch operation unit 15 to turn on the light emitting diode 14, and then installs the gripped illumination device 2 in a flat arbitrary place. At this time, the support portion 9 comes into contact with a flat installation surface. Further, as described above, since the lighting device 2 is waterproof, the lighting device 2 can be installed in a place where there is a risk of getting wet with water or the like. And the said illuminating device 2 installed in arbitrary flat installation surfaces in this way illuminates the circumference | surroundings with the light which the said light emitting diode 14 emitted. That is, the light emitted from the light emitting diode 14 is reflected by the reflecting portion 18, the lower housing 7, the top plate 8, etc., and then passes through the lower housing 7 and the top plate 8 formed of a translucent synthetic resin. The light is transmitted and emitted to the outside of the lighting device 2, and the surroundings of the lighting device 2 are illuminated by the emitted light. The lower casing 7 and the top plate 8 are formed of a semi-transparent synthetic resin, so that light is scattered when passing through the lower casing 7 and the top plate 8, thereby the lighting device. The light emitted from 2 becomes so-called soft light. Further, as described above, since the lower casing 7 is formed of a translucent synthetic resin, the installation surface can be illuminated with the light emitted from the lighting device 2. Furthermore, although the top plate 8 is composed of the flat surface portion 10 and the curved surface portion 11, the surface of the flat surface portion 10 and the surface of the curved surface portion 11 are formed continuously, so that optical characteristics are obtained. That is, the refraction and reflection of light do not change suddenly at the boundary between the flat surface portion 10 and the curved surface portion 11, but gradually change from the flat surface portion 10 to the curved surface portion 11, thereby the top plate 8 is Spots that can be formed in the light that has passed can be reduced, and the appearance can be improved.

そして、このように平坦な設置面上に点灯状態で設置された前記照明装置２の天板８の平面部１０に、被照明物Ａ，Ｂを設置すると、これらの被照明物Ａ，Ｂは、前記天板８を透過した柔らかい光によって照らされる。なお、前記天板８は、周辺部が曲面部１１となっていることで、この曲面部１１に被照明物Ａ，Ｂが設置しにくく、実質的に、中央周辺に形成された平面部１０にのみ被照明物Ａ，Ｂが設置できる。そして、前記平面部１０と曲面部１１の境界が、載置可能な最大重量を有する被照明物Ａ，Ｂを前記平面部１０に載置した状態で、前記照明装置２と被照明物Ａ，Ｂとの合成重心が、前記支持部９で囲まれる範囲の内側となるように規定されているので、前記平面部１０に被照明物Ａ，Ｂを設置する限りにおいて、前記照明装置２が転倒しないようにすることができる。また、前記天板８が前記平面部１０と曲面部１１とで凹状に形成されていることから、前記天板８上に水等の液体がこぼれたとしても、前記天板８で受け止めることができる。これによって、こぼれた液体が設置面を汚す虞を減少させることができる。   And if the to-be-illuminated objects A and B are installed in the plane part 10 of the top plate 8 of the said illuminating device 2 installed in the lighting state on the flat installation surface in this way, these to-be-illuminated objects A and B will be Illuminated by soft light transmitted through the top plate 8. In addition, since the peripheral part of the top plate 8 is the curved surface part 11, it is difficult to place the objects A and B to be illuminated on the curved surface part 11, and the flat part 10 formed substantially around the center. Only the objects to be illuminated A and B can be installed. And in the state which mounted the to-be-illuminated object A and B which has the maximum weight in which the boundary of the said plane part 10 and the curved surface part 11 can be mounted in the said plane part 10, the said illuminating device 2 and the to-be-illuminated object A, Since the combined center of gravity with B is defined to be inside the range surrounded by the support portion 9, as long as the objects to be illuminated A and B are installed on the flat portion 10, the illumination device 2 falls over. You can avoid it. Further, since the top plate 8 is formed in a concave shape by the flat surface portion 10 and the curved surface portion 11, even if a liquid such as water spills on the top plate 8, it can be received by the top plate 8. it can. As a result, the possibility that the spilled liquid may contaminate the installation surface can be reduced.

なお、前記照明装置２は、防水型であること、前記二次電池１３等の重量物が中央下部の前記発光ユニット５に集中しており、低重心であること、前記下筐体７が深皿状に形成されていることなどから、浴槽等、水上に浮かべて安定して使用することができる。このため、水上に浮かべられた前記照明装置２の天板８の平面部１０に前記被照明物Ａ，Ｂを設置することもできる。そして、この際、平坦な設置面に前記照明装置２を設置する場合と同様に、前記被照明物Ａ，Ｂだけでなく、水中も前記下筐体７を透過した光によって照らすことができる。   The lighting device 2 is a waterproof type, heavy objects such as the secondary battery 13 are concentrated on the light emitting unit 5 at the lower center, the center of gravity is low, and the lower housing 7 is deep. Since it is formed in a dish shape, it can float on water such as a bathtub and can be used stably. For this reason, the said to-be-illuminated objects A and B can also be installed in the plane part 10 of the top plate 8 of the said illuminating device 2 floated on water. At this time, similarly to the case where the illumination device 2 is installed on a flat installation surface, not only the objects to be illuminated A and B but also water can be illuminated by light transmitted through the lower housing 7.

以上のように本発明は、平坦な設置面上に設置するための支持部９を有する深皿状の下筐体７と、被照明物Ａ，Ｂが載置可能な平面部１０及びこの平面部１０と連続した曲面部１１によって凹状に形成された天板８とで筐体４を構成し、前記天板８を半透明の合成樹脂で成形し、前記筐体４内に光源としての発光ダイオード１４を設けることで、照明装置２を構成したので、把持部を設けなくても、使用者が前記照明装置２を把持しやすいばかりでなく、前記平面部１０から曲面部１１にかけての光学的な変化が連続的で且つ緩やかであるので、前記天板８を透過した光に斑が少なく、美観を良好にすることができるものである。また、本発明は、前記被照明物Ａ，Ｂが載置可能な前記天板８の平面部１０の範囲を、前記天板８に載置した際に前記天板８の変形量が許容限度となる重量を有する被照明物Ａ，Ｂを前記天板８に載置した状態で、重心が前記支持部９によって定義される範囲の内側となるように、規定したことで、前記平面部１０に載置可能な被照明物Ａ，Ｂを前記平面部１０に載置しても、重心が前記支持部９によって定義される領域から外れないので、前記照明装置２が倒れないようにすることができるものである。更に、本発明は、前記天板８だけでなく、前記下筐体７も半透明の合成樹脂で形成したことで、前記天板８に載置された被照明物Ａ，Ｂだけでなく、前記照明装置２が設置された場所の周囲も照明することができるものである。   As described above, the present invention includes a deep dish-shaped lower housing 7 having a support portion 9 for installation on a flat installation surface, a planar portion 10 on which the objects to be illuminated A and B can be placed, and the plane. The casing 4 is composed of the top plate 8 formed in a concave shape by the curved surface portion 11 that is continuous with the portion 10, the top plate 8 is formed of a semi-transparent synthetic resin, and light emission as a light source is formed in the casing 4. Since the illuminating device 2 is configured by providing the diode 14, the user can easily grasp the illuminating device 2 without providing a gripping portion, and an optical component extending from the flat surface portion 10 to the curved surface portion 11. Since the change is continuous and gentle, the light transmitted through the top plate 8 has few spots, and the appearance can be improved. Further, according to the present invention, when the range of the flat portion 10 of the top plate 8 on which the objects to be illuminated A and B can be placed is placed on the top plate 8, the deformation amount of the top plate 8 is an allowable limit. In the state where the objects A and B having the weight to become are placed on the top plate 8, the plane portion 10 is defined such that the center of gravity is within the range defined by the support portion 9. Even if the objects to be illuminated A and B that can be placed on the flat part 10 are placed, the center of gravity does not deviate from the region defined by the support part 9, so that the lighting device 2 does not fall down. It is something that can be done. Furthermore, in the present invention, not only the top plate 8 but also the lower casing 7 is formed of a translucent synthetic resin, so that not only the illumination objects A and B placed on the top plate 8, The area around the place where the illumination device 2 is installed can also be illuminated.
