【発明の属する技術分野】
この発明は、ダウンライト等に適用する照明器具に関するものである。
【０００２】
【従来の技術】
図１９および図２０は第１の従来例のダウンライト等の埋込型照明器具を示す。すなわち、この埋込型照明器具は、天井５６の埋込孔５７に埋設されて天井面に照射開口５２を有する器具本体５０と、この器具本体５０に納装されたランプソケット５１および反射板５２と、照射開口５２に取付けられた装飾体５３とを備えている。装飾体５３は照射開口５２の縁部に取付けられるリング状の支持体５４と、この支持体５４に吊り下げられた多数の透明部品５５からなる。
【０００３】
図２１および図２２は第２の従来例であるが、装飾体５３が吊棒５９を有するリング状の支持体５４と、吊棒５９に取付けられて照射開口５２を覆う透明板５８からなるものである。
【０００４】
【発明が解決しようとする課題】
しかし、第１の従来例は、各透明部品５５の反射・屈折の光量が少ないことと、透明部品５５が小さい部品の集合であるため輝きが分散してしまい、輝度感によるアイキャッチ効果が低いという欠点があった。また、照明配光も損なわれる。
【０００５】
第２の従来例は、照明配光は損なわれないものの、透明板５８に対して光の入射角と出射角が直角に近いため、透明板５８の端部から出る光量が少なく、輝度感によるアイキャッチ効果が低いという欠点があった。
したがって、この発明の目的は、照明配光をほとんど損なうことなく輝度感のあるアイキャッチ効果を高くでき、にぎやかさや豪華さなど装飾的な光の効果を演出できる照明器具を提供することである。
【０００６】
【課題を解決するための手段】
請求項１記載の照明器具は、照射開口を有する器具本体と、前記照射開口に配置された装飾体とを備え、
前記装飾体は、中央に切欠を有する複数の透光板を、前記切欠で公差状態に噛み合わせたものであり、
各透光板が前記照射開口の投光方向に略平行となる姿勢に配置されて、前記照射開口から突き出した先端の交差部分が突出または凹んでおり、前記透光板の前記照射開口側の端面を入射面とし、前記先端側の端面を出射面としたものである。
【０００７】
請求項１記載の照明器具によれば、器具本体内のランプの点灯により照射開口および透光板を透して光が照射されるので器具本体の照明配光をほとんど損なわない。また光が透光板のランプ側の端縁から入射し透光板内を反射して、主に側縁および先端縁ならびに切欠縁から外方に出射するので、透光板の先端縁および側縁ならびに交差部の切欠縁に輝度感のある発光が可能となる。このため、従来に比して輝度感による高いアイキャッチ効果が得られ、にぎやかさや豪華さなどの装飾的および美的な光を演出することができる。また透光板の平面形状により先端縁側に光を集中したり、平面形状の異なる透光板を交換可能にしたり、あるいは透光板の個数を増加することにより、より一層美的な装飾効果を高められる。
【０００８】
【発明の実施の形態】
この発明の第１の実施の形態を図１ないし図６により説明する。すなわち、この照明器具はダウンライトであり、器具本体１と、装飾体２とを有する。
器具本体１は、照射開口３を有し内部にランプ４を有する。実施の形態では、器具本体１が天井５の埋込孔６に埋設されている。７は照射開口３の縁部に設けられて天井５の埋込孔６の縁部に係止するつば、８（図２等）は器具本体１の側面に設けられて天井５の裏面に係止する取付具、９は器具本体１内に取付けられてランプ４を装着したランプソケット、１０は反射板、１１はつば７を被覆する化粧リングであり、器具本体１にキックばね等の取付手段により取付けられ、反射板１０を支持している。ランプソケット９に給電されてランプ４が点灯すると、ランプ４の直接光および反射板１０の反射光が照射開口３を通して外部に照射し、所定の照明配光を形成する。１９（図２等）は器具本体１の放熱孔である。
【０００９】
装飾体２は、複数の透光板１２，１３からなり、透光板１２，１３に形成した切欠１５，１６で噛み合わせることにより、複数の透光板１２，１３を交差するとともに透光板１２，１３が照射開口３の投光方向に略平行となる姿勢に照射開口３に配置している。実施の形態の装飾体２は、たとえばアクリル板で形成した各透光板１２，１３のランプ４側の端縁１２ａ，１３ａの両側に係止部１７を突設し、端縁１２ａに弧状の凹部１８を形成し、各透光板１２，１３の先端縁および両側縁は略Ｓ字状のやわらかい曲面により連続し、先端縁の中心に突出部２０を形成している。各透光板１２，１３の形状を全体的にみると、いわば平面的にみた漏斗状をなしている。
【００１０】
また透光板１２の切欠１５は先端縁の中心の突出部２０に全高の約１／２の深さで形成し、透光板１３の切欠１６はランプ４側の端縁１２ａの凹部１８の中心に全高の約１／２の深さで形成し、切欠１５，１６が噛み合うように透光板１２，１３を組み合わせた状態で図４に示すように透光板１２，１３を十字に交差した装飾体２を形成している。この装飾体２の係止部１７を化粧リング１１に係止すると、装飾体２が図１および図２に示すように器具本体１に取付けられる。
【００１１】
図１の矢印で示す光線Ｌ₁は、ランプ４の点灯により透光板１２に光が入射した状態を説明している。すなわち、ランプ４の光が凹部１８より透光板１２に略垂直に入射する。そのため屈折光は直進し、透光板１２の先端縁および側縁の略Ｓ状の曲面を一部反射し残部が屈折して外部に出射しその出射部分が発光面となる。また一部反射光は切欠１５の切欠縁を一部反射し残部が屈折して外部に出射しその出射部分が発光面となり、また透光板１２内の一部反射光は次第に突出部２０に集中し、突出部２０における側縁および切欠縁より射出しこれらの部分が発光面となる。
【００１２】
また図５は透光板１３に光Ｌ₂が入射した状態を説明している。すなわち、ランプ４の光が凹部１８より透光板１２に略垂直に入射し、屈折光は直進し、透光板１２の先端縁および側縁の略Ｓ状の曲面を一部反射し残部が屈折して外部に出射しその出射部分が発光面となる。また一部反射光の一部は切欠１６の切欠縁を一部反射し残部が屈折して外部に出射しその出射部分が発光面となり、透光板１２内の一部反射光は次第に突出部２０に集中し、突出部２０における側縁より射出しこの出射部分が発光面となる。
【００１３】
このように、各透光板１２，１３の外形は器具本体１からみた先端側を除々に細くした曲線により形成され、透光板１２，１３の外形の端面での反射光はその曲線の角度により、透光板１２，１３の先端の突出部２０に集まり輝度の高い部分を作る。また図４に示すように二枚の透光板１２，１３の切欠１５，１６を互いに噛み合わせるため、透光板１２，１３の内部を通る光が発光面となる切欠縁のある交差部１４にも現れ、突出部２０の周縁とともに透光板１２，１３の交差部１４に輝度の高い部分を作る。この結果、図６に示すように装飾体２の各透光板１２，１３の側縁および先端縁の発光面のうち輝度の高い部分Ａが突出部２０および交差部１４に現れ、輝度の低い部分Ｂが透光板１２，１３の側縁に現れる。
【００１４】
第１の実施の形態によれば、器具本体１内のランプ４の点灯により照射開口３および透光板１２，１３を透して光が照射されるので、器具本体１の照明配光すなわちダウンライトとしての配光をほとんど損なわない。また光が透光板１２，１３のランプ４側の端縁から入射し透光板１２，１３内を反射して、主に側縁および先端縁ならびに切欠縁から外方に出射するので、透光板１２，１３の先端縁および側縁ならびに交差部の切欠縁に輝度感のある発光が可能となる。このため、従来に比して輝度感による高いアイキャッチ効果が得られ、にぎやかさや豪華さなどの装飾的および美的な光を演出することができる。
【００１５】
また透光板１２，１３の先端縁側に突出部２０を形成しているため、突出部２０および切欠１５，１６の切欠縁に光を集中でき高輝度を発生でき、美的な装飾効果を高めることができる。
この発明の第２の実施の形態を図７ないし図１０に示す。すなわち、この照明器具は、第１の実施の形態において、装飾体２の透光板１２，１３の器具本体１からみた先端側の幅を除々に細くし、先端より１／３ぐらいのところからまた幅を除々に膨らませる曲線で側縁１２ｂ，１３ｂを形成し、その側縁の先端角に一枚当たり２個の角状の張出突部２１を形成するように、張出突部２１から先端縁１２ｃ，１３ｃの中心の交差部１４に向けて切れあがった形状に形成し、各透光板１２，１３は全体的にみて蝶のような鳥羽状に形成している。
【００１６】
この透光板１２，１３の外形の端縁での反射光は図８および図９に光線Ｌ₁，Ｌ₂で示すように、透光板１２，１３の端縁の曲線の角度により、透光板１２，１３の張出突部２１に集まり、図１０に示すように輝度の高い部分Ａを作る。また透光板１２，１３を互いに噛み合わせるための切欠１５，１６は第１の実施の形態と同様であり、したがって透光板１２，１３の交差部１４にも輝度の高い部分Ａを作る。また透光板１２，１３の輝度の低い部分Ｂは透光板１２，１３の側縁となる。
【００１７】
その他は、第１の実施の形態と同様であり、共通部分に同一符号を付している。また第１の実施の形態と同様な効果がある。
この発明の第３の実施の形態を図１１ないし図１４に示す。すなわち、この照明器具は、第１の実施の形態において、装飾体２の透光板１２，１３の器具本体１からみた先端側の幅を除々に細くした曲線により側縁１２ｂ，１３ｂを形成し、先端縁１２ｃ，１３ｃに１枚あたり二つの曲線状の突起部２２を作るように先端縁１２ｃ，１３ｃの交差部１４に向けてきれ上がった形状に形成し、全体として各透光板１２，１３を平面的にみて尻形に形成している。
【００１８】
この透光板１２，１３の外形の端面での反射光Ｌ₁，Ｌ₂はその曲線の角度により、透光板１２，１３の二つの突起部２２に集まり、輝度の高い部分Ａを作る。また二枚の透光板１２，１３は第１の実施の形態と同様な切欠１５，１６を形成し互いに嵌め合わせるため、透光板１２，１３の端部が二枚の透光板１２，１３の交差部１４にも現れ、突起部２２とともにこの鉛直線状の交差部１４にも輝度の高い部分Ａを作り、側縁１２ｂ，１３ｂが輝度の低い部分Ｂとなる。
【００１９】
その他は、第１の実施の形態と同様であり、共通部分に同一符号を付している。また第１の実施の形態と同様な効果がある。
この発明の第４の実施の形態を図１５ないし図１８に示す。すなわち、この照明器具は、第１の実施の形態において、装飾体２の各透光板１２，１３の形状を長方形としたものである。この第４の実施の形態においても各透光板１２，１３の側縁１２ｂ，１３ｂおよび先端縁１２ｃ，１３ｃが発光面となるとともに切欠１５，１６のある交差部１４が発光面となる。この場合、ランプ光の照射方向から考えて先端縁１２ｃ，１３ｃの輝度が側縁１２ｂ，１３ｂの輝度よりも大きい。
【００２０】
その他は、第１の実施の形態と同様であり、共通部分に同一符号を付している。また第１の実施の形態と同様な効果がある。
なお、この発明において、透光板１２，１３の一方のみに切欠１５，１６が形成されてもよく、また一つの透光板１２に複数の透光板が交差してもよく、さらに各透光板１２，１３にそれぞれ複数の透光板を交差させると、美的な装飾効果をより一層高めることができる。
【００２１】
また平面形状の異なる透光板１２等を交換可能にして美的な装飾効果を高めてもよい。
さらに装飾体２は透光板１２，１３を十字に交差したが、９０度以外のたとえばＸ字に交差するものでよく、また交差部１４は中心になくてもよく、たとえばＬ字に交差するものでもよい。
【００２２】
さらに装飾体２の配置は透光板１２，１３が照射開口３の投光方向に略平行であるが、この投光方向が開口面に垂直に限らず斜めである場合をも含む。
また透光板１２，１３の端部が光るため、装飾体２を複数個取付けると高い装飾性があり美的効果があがる。
【００２３】
【発明の効果】
請求項１記載の照明器具によれば、器具本体内のランプの点灯により照射開口および透光板を透して光が照射されるので器具本体の照明配光をほとんど損なわない。また光が透光板のランプ側の端縁から入射し透光板内を反射して、主に側縁および先端縁ならびに切欠縁から外方に出射するので、透光板の先端縁および側縁ならびに交差部の切欠縁に輝度感のある発光が可能となる。このため、従来に比して輝度感による高いアイキャッチ効果が得られ、にぎやかさや豪華さなどの装飾的および美的な光を演出することができる。また透光板の平面形状により先端縁側に光を集中したり、平面形状の異なる透光板を交換可能にしたり、あるいは透光板の個数を増加することにより、より一層美的な装飾効果を高められる。

BACKGROUND OF THE INVENTION
The present invention relates to a lighting apparatus applied to a downlight or the like.
[0002]
[Prior art]
FIGS. 19 and 20 show a first conventional example of an embedded lighting fixture such as a downlight. That is, the embedded lighting fixture includes a fixture main body 50 that is embedded in a buried hole 57 of the ceiling 56 and has an irradiation opening 52 on the ceiling surface, and a lamp socket 51 and a reflector 52 that are housed in the fixture main body 50. And a decorative body 53 attached to the irradiation opening 52. The decorative body 53 includes a ring-shaped support body 54 attached to the edge of the irradiation opening 52 and a large number of transparent parts 55 suspended from the support body 54.
[0003]
FIGS. 21 and 22 show a second conventional example, in which the decorative body 53 includes a ring-shaped support body 54 having a suspension bar 59 and a transparent plate 58 attached to the suspension bar 59 and covering the irradiation opening 52. It is.
[0004]
[Problems to be solved by the invention]
However, in the first conventional example, the amount of reflected and refracted light of each transparent component 55 is small, and since the transparent component 55 is a collection of small components, the brightness is dispersed, and the eye catching effect due to the sense of brightness is low. There was a drawback. Moreover, illumination light distribution is also impaired.
[0005]
In the second conventional example, although the illumination light distribution is not impaired, since the incident angle and the emission angle of the light are close to the right angle with respect to the transparent plate 58, the amount of light emitted from the end of the transparent plate 58 is small, and the luminance is sensed. The eye catching effect was low.
Accordingly, an object of the present invention is to provide a luminaire that can enhance the eye-catching effect with a sense of brightness without substantially impairing the illumination light distribution, and can produce decorative light effects such as liveliness and luxury.
[0006]
[Means for Solving the Problems]
The lighting fixture according to claim 1, comprising: a fixture body having an irradiation opening; and a decorative body arranged in the irradiation opening.
The decorative body is obtained by meshing a plurality of translucent plates having a notch in the center with a tolerance state at the notch,
Each light-transmitting plate is arranged in a posture that is substantially parallel to the projection direction of the irradiation opening, and a crossing portion of the tip protruding from the irradiation opening protrudes or is recessed, and the light-transmitting plate on the irradiation opening side of the light-transmitting plate The end surface is the entrance surface, and the end surface on the tip side is the exit surface .
[0007]
According to the lighting apparatus of the first aspect, since the light is irradiated through the irradiation opening and the translucent plate when the lamp in the apparatus body is turned on, the illumination light distribution of the apparatus body is hardly impaired. In addition, light enters from the edge of the light transmitting plate on the lamp side, reflects inside the light transmitting plate, and mainly exits outward from the side edge, the front edge, and the notch edge. Luminous light emission is possible at the edges and notched edges of the intersections. For this reason, a higher eye catching effect due to a sense of brightness can be obtained as compared with the conventional case, and decorative and aesthetic light such as liveliness and luxury can be produced. In addition, the planar shape of the translucent plate concentrates light on the edge of the tip, makes it possible to exchange translucent plates with different planar shapes, or increases the number of translucent plates, further enhancing the aesthetic decoration effect. It is done.
[0008]

When power is supplied to the lamp socket 9 and the lamp 4 is turned on, the direct light of the lamp 4 and the reflected light of the reflector 10 are irradiated to the outside through the irradiation opening 3 to form a predetermined illumination light distribution. 19 (FIG. 2 etc.) is a heat radiating hole of the instrument body 1.
[0009]
The decorative body 2 includes a plurality of light-transmitting plates 12 and 13, and meshes with notches 15 and 16 formed in the light-transmitting plates 12 and 13, thereby crossing the light-transmitting plates 12 and 13 and the light-transmitting plate. 12 and 13 are arranged in the irradiation opening 3 so as to be substantially parallel to the light projecting direction of the irradiation opening 3. In the decorative body 2 of the embodiment, for example, a locking portion 17 is provided on both sides of the end edges 12a and 13a on the lamp 4 side of each light-transmitting plate 12 and 13 formed of an acrylic plate, and the end edge 12a has an arcuate shape. A concave portion 18 is formed, and the leading edge and both side edges of each of the translucent plates 12 and 13 are continuous by a substantially S-shaped soft curved surface, and a protruding portion 20 is formed at the center of the leading edge. If the shape of each translucent plate 12 and 13 is seen as a whole, it will be in a so-called funnel shape in plan view.
[0010]
Further, the notch 15 of the light transmitting plate 12 is formed in the projecting portion 20 at the center of the tip edge to a depth of about ½ of the total height, and the notch 16 of the light transmitting plate 13 is formed in the recess 18 of the edge 12a on the lamp 4 side. The light transmitting plates 12 and 13 are crossed in a cross shape as shown in FIG. 4 with the light transmitting plates 12 and 13 combined so that the notches 15 and 16 engage with each other. The decorative body 2 is formed. When the locking portion 17 of the decorative body 2 is locked to the decorative ring 11, the decorative body 2 is attached to the instrument body 1 as shown in FIGS. 1 and 2.
[0011]
A light beam L ₁ indicated by an arrow in FIG. 1 explains a state in which light is incident on the translucent plate 12 by lighting the lamp 4. That is, the light from the lamp 4 enters the light transmitting plate 12 through the recess 18 substantially perpendicularly. Therefore, the refracted light travels straight, partially reflects the substantially S-shaped curved surface at the leading edge and side edge of the light transmitting plate 12, the remaining part is refracted and emitted to the outside, and the emission part becomes the light emitting surface. Further, the partially reflected light partially reflects the notch edge of the notch 15, the remaining part is refracted and emitted to the outside, and the emitted part becomes a light emitting surface, and the partially reflected light in the translucent plate 12 gradually reaches the projecting part 20. It concentrates and inject | emits from the side edge and notch edge in the protrusion part 20, and these parts become a light emission surface.
[0012]
FIG. 5 illustrates a state where the light L ₂ is incident on the light transmitting plate 13. That is, the light from the lamp 4 enters the translucent plate 12 from the recess 18 substantially perpendicularly, the refracted light travels straight, partially reflects the substantially S-shaped curved surface of the front edge and side edge of the translucent plate 12, and the remaining part is The light is refracted and emitted to the outside, and the emission part becomes a light emitting surface. Further, a part of the partially reflected light partially reflects the notch edge of the notch 16, the remaining part is refracted and emitted to the outside, and the exit part becomes a light emitting surface, and the partially reflected light in the translucent plate 12 gradually protrudes. The light exits from the side edge of the protrusion 20 and becomes a light emitting surface.
[0013]
As described above, the outer shape of each of the translucent plates 12 and 13 is formed by a curved line that is formed by gradually narrowing the distal end side viewed from the instrument body 1, and the reflected light at the outer end face of the translucent plates 12 and 13 is the angle of the curved line As a result, the light-transmitting plates 12 and 13 gather together at the protrusions 20 at the tips of the light-transmitting plates 12 and 13 to create a high-luminance portion. Further, as shown in FIG. 4, in order to mesh the notches 15 and 16 of the two light-transmitting plates 12 and 13, the crossing portion 14 having a notch edge where the light passing through the light-transmitting plates 12 and 13 becomes a light emitting surface. In addition to the peripheral edge of the protrusion 20, a high-luminance portion is formed at the intersection 14 of the light-transmitting plates 12 and 13. As a result, as shown in FIG. 6, a high-luminance portion A of the light-emitting surfaces of the side and tip edges of the light-transmitting plates 12 and 13 of the decorative body 2 appears at the protrusions 20 and the intersections 14, and the luminance is low. Part B appears on the side edges of the light-transmitting plates 12 and 13.
[0014]
According to the first embodiment, light is emitted through the irradiation opening 3 and the light-transmitting plates 12 and 13 when the lamp 4 in the instrument body 1 is turned on. Light distribution as a light is hardly impaired. Further, light enters from the edge of the translucent plates 12 and 13 on the lamp 4 side, reflects inside the translucent plates 12 and 13, and exits mainly from the side edge, the tip edge and the cutout edge. Luminous light emission is possible at the leading edge and side edges of the light plates 12 and 13 and at the notched edges of the intersections. For this reason, a higher eye catching effect due to a sense of brightness can be obtained as compared with the conventional case, and decorative and aesthetic light such as liveliness and luxury can be produced.
[0015]
Moreover, since the protrusion part 20 is formed in the front end edge side of the translucent plates 12 and 13, light can be concentrated on the notch edge of the protrusion part 20 and the notches 15 and 16, high brightness can be generated, and the aesthetic decoration effect is enhanced. Can do.
A second embodiment of the present invention is shown in FIGS. That is, in the first embodiment, the lighting fixture is formed by gradually narrowing the width of the light transmitting plate 12 and 13 of the decorative body 2 on the tip side as seen from the tool body 1 and from about 1/3 of the tip. Further, the side edges 12b and 13b are formed by curves that gradually increase in width, and the two protruding protrusions 21 are formed at the leading edge of each side edge so as to form two rectangular protruding protrusions 21 per sheet. The light-transmitting plates 12 and 13 are formed in a bird-like shape like a butterfly as a whole as viewed from the center of the leading edges 12c and 13c.
[0016]
Reflected light at the outer edge of the light-transmitting plates 12 and 13 is transmitted by the angle of the curve of the edge of the light-transmitting plates 12 and 13 as shown by light rays L ₁ and L ₂ in FIGS. As shown in FIG. 10, a portion A having a high luminance is formed by gathering at the protruding protrusions 21 of the optical plates 12 and 13. Further, the notches 15 and 16 for engaging the light transmitting plates 12 and 13 with each other are the same as those in the first embodiment. Therefore, a high-luminance portion A is formed at the intersection 14 of the light transmitting plates 12 and 13. Further, the low-brightness portion B of the light-transmitting plates 12 and 13 is the side edge of the light-transmitting plates 12 and 13.
[0017]
Others are the same as those in the first embodiment, and common portions are denoted by the same reference numerals. Also, there are the same effects as those of the first embodiment.
A third embodiment of the present invention is shown in FIGS. That is, this lighting fixture forms the side edges 12b and 13b by the curve which narrowed the width | variety of the front end side seen from the fixture main body 1 of the translucent board 12 and 13 of the decoration body 2 in 1st Embodiment. Each of the light-transmitting plates 12, 13 c is formed in a shape that rises toward the intersecting portion 14 of the tip edges 12 c, 13 c so as to form two curved projections 22 on the tip edges 12 c, 13 c. 13 is formed in a butt shape in plan view.

Reflected lights L ₁ and L _{2 on} the outer end faces of the light-transmitting plates 12 and 13 gather at the two protrusions 22 of the light-transmitting plates 12 and 13 according to the angle of the curve to form a high-luminance portion A. Further, since the two light-transmitting plates 12 and 13 form notches 15 and 16 similar to those in the first embodiment and are fitted to each other, the end portions of the light-transmitting plates 12 and 13 are the two light-transmitting plates 12 and 13. 13 also appears at the intersection 14 and the projection 22 and the vertical line-shaped intersection 14 has a high luminance portion A, and the side edges 12b and 13b become low luminance portions B.
[0019]
Others are the same as those in the first embodiment, and common portions are denoted by the same reference numerals. Also, there are the same effects as those of the first embodiment.
A fourth embodiment of the present invention is shown in FIGS. That is, in this lighting device, the shape of each light-transmitting plate 12, 13 of the decorative body 2 is a rectangle in the first embodiment. Also in the fourth embodiment, the side edges 12b and 13b and the tip edges 12c and 13c of the light-transmitting plates 12 and 13 become light emitting surfaces, and the intersecting portion 14 with the notches 15 and 16 becomes light emitting surfaces. In this case, the brightness of the leading edges 12c and 13c is larger than the brightness of the side edges 12b and 13b in view of the irradiation direction of the lamp light.
[0020]
Others are the same as those in the first embodiment, and common portions are denoted by the same reference numerals. Also, there are the same effects as those of the first embodiment.
In the present invention, the notches 15 and 16 may be formed in only one of the light-transmitting plates 12 and 13, or a plurality of light-transmitting plates may intersect with one light-transmitting plate 12. When a plurality of light-transmitting plates are crossed with the light plates 12 and 13, respectively, the aesthetic decoration effect can be further enhanced.
[0021]
Further, the translucent plate 12 having a different planar shape may be exchanged to enhance the aesthetic decoration effect.
Further, the decorative body 2 crosses the translucent plates 12 and 13 in a cross shape, but may cross, for example, an X shape other than 90 degrees, and the crossing portion 14 may not be in the center, for example, crosses an L shape. It may be a thing.
[0022]
Further, the arrangement of the decorative body 2 includes the case where the translucent plates 12 and 13 are substantially parallel to the light projecting direction of the irradiation opening 3, but this light projecting direction is not limited to being perpendicular to the opening surface but is oblique.
Moreover, since the edge part of the light-transmitting plates 12 and 13 shines, when a plurality of decorative bodies 2 are attached, there is a high decorative property and an aesthetic effect is improved.

【The invention's effect】
According to the lighting apparatus of the first aspect, since the light is irradiated through the irradiation opening and the translucent plate when the lamp in the apparatus body is turned on, the illumination light distribution of the apparatus body is hardly impaired. In addition, light enters from the edge of the light transmitting plate on the lamp side, reflects inside the light transmitting plate, and mainly exits outward from the side edge, the front edge, and the notch edge. Luminous light emission is possible at the edges and notched edges of the intersections. For this reason, a higher eye catching effect due to a sense of brightness can be obtained as compared with the conventional case, and decorative and aesthetic light such as liveliness and luxury can be produced. In addition, the planar shape of the translucent plate concentrates light on the edge of the tip, makes it possible to exchange translucent plates with different planar shapes, or increases the number of translucent plates, further enhancing the aesthetic decoration effect. It is done.
