以下、一実施形態を、図1ないし図3を参照して説明する。   Hereinafter, an embodiment will be described with reference to FIGS. 1 to 3.

図3に示すように、照明器具10は、天井面に設置されている引掛シーリングボディにアダプタを介して取り付けられるシーリングライトである。   As shown in FIG. 3, the luminaire 10 is a ceiling light that is attached to a hooked ceiling body installed on a ceiling surface via an adapter.

照明器具10は、器具本体11を備え、この器具本体11の下面側に発光モジュール12および透光カバー13が配置されているとともにセード14が着脱可能に取り付けられ、器具本体11の上面側に化粧枠15および図示しない点灯装置を内蔵した上面カバー16(図1参照)が取り付けられている。器具本体11の中央および上面カバー16の中央にはアダプタに着脱可能に取り付けられる筒状のアダプタガイド17が配設されている。   The lighting fixture 10 includes a fixture main body 11, a light emitting module 12 and a translucent cover 13 are disposed on the lower surface side of the fixture main body 11, a shade 14 is detachably attached, and a makeup is provided on the upper surface side of the fixture main body 11. A top cover 16 (see FIG. 1) incorporating a frame 15 and a lighting device (not shown) is attached. A cylindrical adapter guide 17 that is detachably attached to the adapter is disposed in the center of the instrument body 11 and the center of the upper surface cover 16.

そして、器具本体11は、金属製で円盤状に形成されている。器具本体11の一面である下面には、中央域に円形の突出部20が一体に突出され、この突出部20の周囲に環状の基板取付部21が形成されている。突出部20の中央にはアダプタガイド17が嵌り込む開口部22が形成されている。基板取付部21の周辺側には発光モジュール12の位置決め用の複数の突起23が突設されているとともに透光カバー13の取付用である周方向に長い長孔状の複数の挿通孔24が形成され、基板取付部21の中央側にはねじ止め用の複数の取付孔25が形成されている。また、器具本体11の周辺部には、セード14を回動させることによって、セード14を器具本体11に対して着脱可能に取り付ける複数のセード取付金具26が取り付けられている。   The instrument body 11 is made of metal and has a disk shape. On the lower surface, which is one surface of the instrument body 11, a circular protrusion 20 is integrally protruded in the central region, and an annular substrate mounting portion 21 is formed around the protrusion 20. An opening 22 into which the adapter guide 17 is fitted is formed at the center of the protrusion 20. A plurality of protrusions 23 for positioning the light emitting module 12 are provided on the peripheral side of the board mounting portion 21 and a plurality of long insertion holes 24 in the circumferential direction for mounting the light transmitting cover 13 are provided. A plurality of mounting holes 25 for screwing are formed on the center side of the board mounting portion 21. In addition, a plurality of shade mounting brackets 26 are attached to the peripheral portion of the instrument body 11 so that the shade 14 is detachably attached to the instrument body 11 by rotating the shade 14.

また、発光モジュール12は、基板29、およびこの基板29に実装された複数の発光素子30を備えている。基板29は、半環状に形成されており、一対の基板29が器具本体11の基板取付部21に配置されることによって一対の基板29が環状に組み合わされる。基板29の周辺部には、各突起23に嵌って位置決めされる複数の位置決め溝31が形成されている。   The light emitting module 12 includes a substrate 29 and a plurality of light emitting elements 30 mounted on the substrate 29. The substrate 29 is formed in a semi-annular shape, and the pair of substrates 29 are annularly combined by arranging the pair of substrates 29 on the substrate mounting portion 21 of the instrument body 11. In the peripheral portion of the substrate 29, a plurality of positioning grooves 31 that are positioned by being fitted to the protrusions 23 are formed.

基板29の前面である実装面には、配線パターンが形成され、この配線パターンに例えばLED素子や有機ELなどを含む複数の発光素子30が同心円上に複数列実装されている。実施形態では、発光素子30として、面実装タイプのSMDパッケージ式のLED素子が用いられている。そして、複数の発光素子30が基板29に円周方向に沿って所定の間隔に配列されているとともに同心円上に2列配置されている。発光素子30の発光部は基板29の実装面に対して反対方向であって照明器具10の天井設置状態で直下方向に向けられる。さらに、基板29の実装面には、配線パターンを覆って高反射率特性を有する反射面が形成されている。   A wiring pattern is formed on the mounting surface which is the front surface of the substrate 29, and a plurality of light emitting elements 30 including, for example, LED elements and organic EL are mounted in a concentric circle on the wiring pattern. In the embodiment, as the light emitting element 30, a surface mount type SMD package type LED element is used. A plurality of light emitting elements 30 are arranged on the substrate 29 at a predetermined interval along the circumferential direction and are arranged in two rows on concentric circles. The light emitting part of the light emitting element 30 is directed in the opposite direction with respect to the mounting surface of the substrate 29 and directly downward when the lighting fixture 10 is installed on the ceiling. Further, a reflective surface having a high reflectance characteristic is formed on the mounting surface of the substrate 29 so as to cover the wiring pattern.

発光素子30には、少なくとも2以上の異なる色温度の発光素子を混在して用い、調色できるようにしてもよい。例えば、3000Kの色温度の発光素子と、6500Kの色温度の発光素子とを混在して用いる。さらに、同一の色温度で、演色性の異なる発光素子を用い、演色性を変化させるようにしてもよい。例えば、3000Kの色温度で平均演色評価数がRa85とRa90の発光素子を1:1の関係で混在し、6500Kの色温度で平均演色評価数がRa85とRa90の発光素子を1:1の関係で混在する。この場合、3000K、6500Kの発光素子のそれぞれの単色点灯時の平均演色評価数はRa88であるが、3000Kおよび6500Kの全ての発光素子の点灯時の平均演色評価数はRa91程度に向上する。これは、Ra90の発光素子にRa85の発光素子が半分混ざっているため、Ra90の発光素子のみを点灯させる場合よりも効率が高くなることによる。そして、異なる色温度および演色性の発光素子をそれぞれ独立して点灯制御するように構成することにより、例えば同じ色温度でも演色性を変化させることができる。   The light emitting element 30 may be a mixture of at least two light emitting elements having different color temperatures so that the color can be adjusted. For example, a light emitting element having a color temperature of 3000K and a light emitting element having a color temperature of 6500K are used in combination. Furthermore, the color rendering properties may be changed by using light emitting elements having different color rendering properties at the same color temperature. For example, light emitting elements with an average color rendering index of Ra85 and Ra90 are mixed in a 1: 1 relationship at a color temperature of 3000K, and a light emitting element with an average color rendering index of Ra85 and Ra90 is at a 1: 1 relationship at a color temperature of 6500K. Mixed. In this case, the average color rendering index when the single color lighting of each of the 3000K and 6500K light emitting elements is Ra88, but the average color rendering index when all the 3000K and 6500K light emitting elements are turned on is improved to about Ra91. This is because the Ra90 light-emitting element is mixed with half of the Ra85 light-emitting element, and the efficiency is higher than when only the Ra90 light-emitting element is turned on. In addition, by configuring the light emitting elements having different color temperatures and color rendering properties to be controlled independently, the color rendering properties can be changed even at the same color temperature, for example.

一対の基板29の互いに対向する両端部にはコネクタ32が実装されている。一方の端部に実装されたコネクタ32は一対の基板を電気的に接続するのに使用され、他方の端部に実装されたコネクタ32は各基板29と点灯装置とを電気的に接続するのに利用される。   Connectors 32 are mounted on opposite ends of the pair of substrates 29. The connector 32 mounted on one end is used to electrically connect a pair of substrates, and the connector 32 mounted on the other end electrically connects each substrate 29 and the lighting device. Used for

また、図1および図3に示すように、透光カバー13は、光透過性および導光性を有する透明な樹脂製で、中央に開口部35を有する環状に形成されている。透光カバー13は、基板29を器具本体11との間に挟み込んで覆うことが可能な大きさに形成された環状で平板状の覆い部36を有している。   As shown in FIGS. 1 and 3, the translucent cover 13 is made of a transparent resin having a light transmitting property and a light guiding property, and is formed in an annular shape having an opening 35 at the center. The translucent cover 13 has an annular flat plate-like cover portion 36 that is formed in such a size that the substrate 29 can be sandwiched between and covered with the instrument body 11.

覆い部36の背面側で外周部には、器具本体11の各挿通孔24に挿通可能とする複数の係止部37が一体に突出形成されている。これら複数の係止部37は、透光カバー13の周方向の一方である装着回動方向へ向けて略L字形状の爪にて形成されている。そして、各係止部37を器具本体11の各挿通孔24に挿通して透光カバー13を装着回動方向に回動させることにより、各係止部37の先端が器具本体11の背面側に乗り上げて透光カバー13を器具本体11に向けて引き寄せるとともに、各係止部37が器具本体11の背面側に引っ掛かって器具本体11と透光カバー13との間に基板29を挟持した状態で器具本体11と透光カバー13とが固定される。   A plurality of locking portions 37 that can be inserted into the respective insertion holes 24 of the instrument body 11 are integrally formed on the outer peripheral portion on the back side of the cover portion 36 so as to protrude. The plurality of locking portions 37 are formed by substantially L-shaped claws in the mounting rotation direction that is one of the circumferential directions of the translucent cover 13. Then, by inserting each locking portion 37 into each insertion hole 24 of the instrument main body 11 and rotating the translucent cover 13 in the mounting rotation direction, the tip of each locking portion 37 is on the back side of the instrument main body 11 The translucent cover 13 is pulled toward the instrument main body 11 and the locking part 37 is caught on the back side of the instrument main body 11 so that the substrate 29 is sandwiched between the instrument main body 11 and the translucent cover 13 Thus, the instrument body 11 and the translucent cover 13 are fixed.

透光カバー13の内周部には、ねじで透光カバー13を器具本体11に固定する複数のねじ挿通孔38が設けられている。   A plurality of screw insertion holes 38 for fixing the translucent cover 13 to the instrument body 11 with screws are provided in the inner peripheral portion of the translucent cover 13.

覆い部36には、基板29に同心円上に2列に配列された発光素子30にそれぞれ対向するように環状のレンズ部39が同心円上に2列形成されている。図1および図2に示すように、レンズ部39は、覆い部36の背面側に開口して発光素子30を収容する凹部40を有していて、覆い部36の前面側に突出する断面略山形に形成されており、環状方向である周方向に同じ断面形状に形成されている。凹部40の内面には発光素子30からの光を入射する入射面39aが形成され、レンズ部39の外面にレンズ部39内に入射した光が出射する出射面39bが形成されている。このレンズ部39によって、発光素子30から出射される光を器具本体11(セード14)の中央側および周辺側へ向けて鉛直角60°〜70°にピークを有する広がる配光に制御する。図2に示すように、基板29に対向する覆い部36の背面側で少なくともレンズ部39の背面側の領域には、光拡散部41が形成されている。光拡散部41は、例えば覆い部36の背面側に凹凸パターンを施すことによって形成しているが、拡散シートを貼り付けるなど、別の手段を用いてもよい。   In the cover portion 36, two annular lens portions 39 are formed on the concentric circle so as to face the light emitting elements 30 arranged on the substrate 29 in two rows concentrically. As shown in FIGS. 1 and 2, the lens portion 39 has a recess 40 that opens to the back surface side of the cover portion 36 and accommodates the light emitting element 30, and has a cross section that protrudes to the front surface side of the cover portion 36. It is formed in the shape of a mountain and is formed in the same cross-sectional shape in the circumferential direction that is the annular direction. An incident surface 39a for incident light from the light emitting element 30 is formed on the inner surface of the recess 40, and an output surface 39b for emitting light incident on the lens portion 39 is formed on the outer surface of the lens portion 39. By this lens unit 39, the light emitted from the light emitting element 30 is controlled to spread light distribution having a peak at a vertical angle of 60 ° to 70 ° toward the center side and the peripheral side of the instrument body 11 (sade 14). As shown in FIG. 2, a light diffusion portion 41 is formed in a region on the back side of the cover portion 36 facing the substrate 29 and at least on the back side of the lens portion 39. The light diffusing portion 41 is formed, for example, by applying a concavo-convex pattern on the back side of the covering portion 36, but other means such as attaching a diffusion sheet may be used.

図1ないし図3に示すように、覆い部36には、一対のレンズ部39間に、基板29のコネクタ32の位置に対応して逃し部42が形成されている。この逃し部42は、覆い部36の背面側に開口してコネクタ32を収容する凹部43を有していて、覆い部36の前面側に突出して形成されており、環状方向である周方向にコネクタ32の寸法よりも長い寸法に形成されている。すなわち、透光カバー13は回動させることによって器具本体11に着脱する構造であるため、その回動させる際に、コネクタ32と干渉しないように逃し部42が周方向に長く形成されている。なお、本実施形態では、基板29のコネクタ32が周方向の2箇所であるのに対して、透光カバー13の逃し部42が周方向の4箇所にあり、透光カバー13を取り付ける向きの選択の範囲を多くして組立性を良好にしているが、透光カバー13の逃し部42は周方向の少なくとも2箇所にあればよい。   As shown in FIGS. 1 to 3, the cover portion 36 is formed with a relief portion 42 between the pair of lens portions 39 corresponding to the position of the connector 32 of the substrate 29. The relief portion 42 has a recess 43 that opens to the back side of the cover portion 36 and accommodates the connector 32, and is formed to protrude to the front side of the cover portion 36, and is formed in a circumferential direction that is an annular direction. The dimension is longer than the dimension of the connector 32. That is, since the translucent cover 13 is structured to be attached to and detached from the instrument main body 11 by rotating, the relief portion 42 is formed long in the circumferential direction so as not to interfere with the connector 32 when rotating. In the present embodiment, the connector 32 of the substrate 29 is provided at two locations in the circumferential direction, whereas the relief portions 42 of the translucent cover 13 are provided at four locations in the circumferential direction, so that the translucent cover 13 is attached. Although the range of selection is increased to improve the assemblability, the relief portions 42 of the translucent cover 13 may be provided in at least two places in the circumferential direction.

また、セード14は、透光性を有する樹脂製で、上面側が開口され、上面側の内周縁部に各セード取付金具26に取り付けられる図示しない取付段部が形成されている。セード14の下面部14aは、なだらかに湾曲突出するようにドーム状に形成されている。そして、器具本体11に取り付けられるセード14により、器具本体11の下面、基板29および透光カバー13などが覆われる。   The shade 14 is made of a resin having translucency, and the upper surface side is opened, and an attachment step portion (not shown) attached to each of the shade attachment brackets 26 is formed on the inner peripheral edge portion on the upper surface side. The lower surface portion 14a of the shade 14 is formed in a dome shape so as to be curved and protrude gently. Then, the shade 14 attached to the instrument body 11 covers the lower surface of the instrument body 11, the substrate 29, the translucent cover 13, and the like.

セード14の内面全域には、例えば乳白色に形成されたものであって光拡散性を有する所定の光透過率の光透過領域(光拡散領域)46が形成されている。セード14の下面14aには、光透過領域46中に光透過率が光透過領域46よりも相対的に大きい複数の高透過率部47が形成されている。高透過率部47は、例えば光透過領域46が形成されていない小さなドットによって構成され、複数のドットが下面部14aにおける光透過領域46の全域にランダムに点在して配置されている。   A light transmission region (light diffusion region) 46 having a predetermined light transmittance, which is formed in, for example, milky white color and has light diffusibility, is formed on the entire inner surface of the shade 14. On the lower surface 14 a of the shade 14, a plurality of high transmittance portions 47 having a light transmittance relatively higher than that of the light transmission region 46 are formed in the light transmission region 46. The high transmittance portion 47 is constituted by, for example, small dots in which the light transmission region 46 is not formed, and a plurality of dots are randomly scattered throughout the light transmission region 46 in the lower surface portion 14a.

また、図2に示すように、化粧枠15は、透光性を有する樹脂製で環状に形成され、内周側縁部が器具本体11の背面側に取り付けられている。そして、セード14の周囲を透過する光が化粧枠15に入射して化粧枠15も光るように構成されている。   As shown in FIG. 2, the decorative frame 15 is made of a light-transmitting resin and is formed in an annular shape, and an inner peripheral edge is attached to the back side of the instrument body 11. And the light which permeate | transmits the circumference | surroundings of the shade 14 enters into the decorative frame 15, and it is comprised so that the decorative frame 15 may also shine.

また、上面カバー16内に配置されている点灯装置は、アダプタおよび引掛シーリングを通じて商用交流電源が入力され、入力された交流電源を整流平滑し、所定の直流電源に変換して発光素子30に供給する。   The lighting device arranged in the upper surface cover 16 receives commercial AC power through an adapter and hook ceiling, rectifies and smoothes the input AC power, converts it to a predetermined DC power, and supplies it to the light emitting element 30. To do.

次に、照明器具10を組み立てるには、アダプタガイド17および点灯装置などを取り付けた上面カバー16、および化粧枠15を、器具本体11の上面に取り付ける。   Next, in order to assemble the lighting fixture 10, the top cover 16 to which the adapter guide 17 and the lighting device are attached, and the decorative frame 15 are attached to the top surface of the fixture main body 11.

器具本体11の基板取付部21が上方に向くように上下を反転させた状態で、基板取付部21に基板29を載置し、基板29の各位置決め溝31を基板取付部21の各突起23に嵌め込む。これにより、基板29が器具本体11の基板取付部21の面に沿った方向(水平方向)の位置が位置決め保持される。さらに、両基板29間や基板29と点灯装置との間の配線を行う。   With the substrate mounting portion 21 of the instrument body 11 turned upside down so that the substrate mounting portion 21 faces upward, the substrate 29 is placed on the substrate mounting portion 21, and each positioning groove 31 of the substrate 29 is inserted into each projection 23 of the substrate mounting portion 21. Fit into. Thereby, the position of the substrate 29 in the direction (horizontal direction) along the surface of the substrate attachment portion 21 of the instrument body 11 is positioned and held. Further, wiring is performed between both the substrates 29 and between the substrate 29 and the lighting device.

基板29を覆うように透光カバー13を被せながら、透光カバー13の各係止部37を器具本体11の各挿通孔24に挿通させ、透光カバー13を装着回動方向に回動させることにより、各係止部37の先端が器具本体11の背面側に乗り上げて透光カバー13を器具本体11に向けて引き寄せる。これにより、透光カバー13の覆い部36の背面側が基板29に当接し、基板29を器具本体11に押圧する。そして、各係止部37が器具本体11の背面側に引っ掛かると、器具本体11と透光カバー13との間に基板29を挟持した状態で器具本体11と透光カバー13とが固定される。このとき、レンズ部39が周方向に同じ断面形状に形成されているとともに、逃し部42がコネクタ32と干渉しないように周方向に長く形成されているため、これらレンズ部39や逃し部42が影響することなく、透光カバー13を回動させて装着することができる。   While covering the substrate 29 with the translucent cover 13, the locking portions 37 of the translucent cover 13 are inserted into the insertion holes 24 of the instrument body 11, and the translucent cover 13 is rotated in the mounting rotation direction. As a result, the tip of each locking portion 37 rides on the back side of the instrument body 11 and draws the translucent cover 13 toward the instrument body 11. As a result, the back side of the cover portion 36 of the translucent cover 13 contacts the substrate 29 and presses the substrate 29 against the instrument body 11. Then, when each locking portion 37 is hooked on the back side of the instrument body 11, the instrument body 11 and the translucent cover 13 are fixed in a state where the substrate 29 is sandwiched between the instrument body 11 and the translucent cover 13. . At this time, the lens portion 39 is formed in the same cross-sectional shape in the circumferential direction, and since the escape portion 42 is formed long in the circumferential direction so as not to interfere with the connector 32, the lens portion 39 and the relief portion 42 are The translucent cover 13 can be rotated and mounted without being affected.

ねじを透光カバー13のねじ挿通孔38を通じて器具本体11の取付孔25にねじ込んで固定し、透光カバー13を器具本体11に確実に固定する。   A screw is screwed into the mounting hole 25 of the instrument main body 11 through the screw insertion hole 38 of the translucent cover 13 and fixed, so that the translucent cover 13 is securely fixed to the instrument main body 11.

セード14を器具本体11の下側から被せ、所定の装着回動方向に回動させることにより、セード14をセード取付金具26によって器具本体11に取り付ける。   The shade 14 is attached to the instrument body 11 by the shade mounting bracket 26 by covering the shade 14 from the lower side of the instrument body 11 and rotating it in a predetermined mounting rotation direction.

なお、照明器具10の組立順序は、このような順序に限られるものではない。   Note that the assembly order of the lighting fixtures 10 is not limited to such an order.

そして、照明器具10を設置するには、予めセード14を外した照明器具10のアダプタガイド17を天井面の引掛シーリングに装着したアダプタに取り付ける。アダプタから導出されている配線を点灯装置側と接続し、引掛シーリングと点灯装置とを電気的に接続する。セード14を器具本体11に装着する。   In order to install the luminaire 10, the adapter guide 17 of the luminaire 10 with the shade 14 removed in advance is attached to the adapter mounted on the ceiling ceiling ceiling. The wiring led out from the adapter is connected to the lighting device side, and the hook ceiling and the lighting device are electrically connected. Attach the shade 14 to the instrument body 11.

そして、照明器具10の点灯時には、点灯装置によって商用交流電源を所定の直流電力に変換して複数の発光素子30に供給し、複数の発光素子30が点灯する。   When the lighting fixture 10 is turned on, the commercial AC power is converted into predetermined DC power by the lighting device and supplied to the plurality of light emitting elements 30, and the plurality of light emitting elements 30 are turned on.

点灯した複数の発光素子30から出射する光は、透光カバー13のレンズ部39に入射され、このレンズ部39によって器具本体11の中央側および周辺側に広がる配光に制御されてセード14の内側空間に出射され、セード14に入射するとともにセード14を透過して照明空間に照射される。   Light emitted from the plurality of light-emitting elements 30 that are lit is incident on the lens portion 39 of the translucent cover 13, and is controlled by the lens portion 39 so that the light distribution spreads to the center side and the peripheral side of the instrument body 11, and the shade 14 The light is emitted into the inner space, enters the shade 14, and passes through the shade 14 to irradiate the illumination space.

セード14の内側空間から光透過領域46に入射した光は拡散され、セード14の光透過領域46の全体が均一に光る。特に、レンズ部39によって、発光素子30から出射される光をセード14の中央側および周辺側へ向けてピークを有する広がる配光に制御しているため、セード14の光透過領域46の全体が均一に光りやすくできる。   The light incident on the light transmission region 46 from the inner space of the shade 14 is diffused, and the entire light transmission region 46 of the shade 14 shines uniformly. In particular, since the light emitted from the light emitting element 30 is controlled by the lens unit 39 to spread light distribution having peaks toward the central side and the peripheral side of the shade 14, the entire light transmission region 46 of the shade 14 is controlled. Uniform and easy to shine.

セード14の内側空間から複数の高透過率部47に入射した光はあまり拡散されることなくセード14を透過する。そのため、セード14を見た際に、セード14の均一に光る光透過領域46に複数の高透過率部47を透過した光による複数の輝きが点在し、複数のきらめき光として見え、さらに、セード14を見る位置が変化することで、複数のきらめき光がきらめいて見える演出効果を得ることができる。   The light incident on the plurality of high transmittance portions 47 from the inner space of the shade 14 passes through the shade 14 without being diffused much. Therefore, when looking at the shade 14, the light transmission region 46 of the shade 14 that uniformly shines is dotted with a plurality of sparkles due to the light transmitted through the plurality of high transmittance portions 47, and appears as a plurality of sparkling lights, By changing the position where the shade 14 is viewed, it is possible to obtain a production effect in which a plurality of glitter lights are seen.

このきらめき感は、発光素子30からの光が高透過率部47を通じて出射される方向からセード14を見たときに得られやすく、そのため、発光素子30の光は下方へ向けて出射されるため、セード14を下方から見た場合にきらめき感が得られやすい。さらに、レンズ部39によって、発光素子30から出射される光をセード14の中央側および周辺側へ向けてピークを有する広がる配光に制御しているため、セード14を斜め方向から見た場合にも、セード14の中央領域から周辺領域に亘る全体域できらめき感が得られやすい。したがって、セード14をどの方向から見てもきらめき感が得られやすくなり、演出効果を向上できる。   This glittering feeling is easily obtained when the shade 14 is viewed from the direction in which the light from the light emitting element 30 is emitted through the high transmittance portion 47, and thus the light from the light emitting element 30 is emitted downward. When the shade 14 is viewed from below, a glittering feeling is easily obtained. Further, since the light emitted from the light emitting element 30 is controlled by the lens unit 39 to spread light distribution having peaks toward the central side and the peripheral side of the shade 14, when the shade 14 is viewed from an oblique direction, However, it is easy to obtain a glittering feeling in the entire region from the central region of the shade 14 to the peripheral region. Therefore, it is easy to obtain a sparkle no matter which direction the shade 14 is viewed from, and the production effect can be improved.

レンズ部39を用いていることにより、レンズ部39を斜め方向から見た場合に発光素子30の発光部が拡大されて見えるため、セード14を斜め方向から見た場合に、高透過率部47を通じて拡大された発光素子30の発光部が投影され、きらめき感が向上する。   By using the lens part 39, the light emitting part of the light emitting element 30 appears to be enlarged when the lens part 39 is viewed from an oblique direction. Therefore, when the shade 14 is viewed from an oblique direction, the high transmittance part 47 The light emitting part of the light emitting element 30 enlarged through is projected, and the glittering feeling is improved.

また、図2に示すように、発光素子30からレンズ部39に入射した光の一部が出射面39bで反射してレンズ部39の背面側に向かう。レンズ部39の背面側の領域には光拡散部41が形成されているが、仮に形成されていなかった場合には、レンズ部39の背面側の領域である覆い部36の背面で光が反射し、この光がレンズ部39から出射されることで輝線が発生し、この輝線がセード14の光透過領域46に映り込むことで、セード14の光透過領域46に輝度むらが生じることになる。それに対して、レンズ部39の背面側の領域に光拡散部41が形成されていることにより、レンズ部39の背面側に向かった光が光拡散部41で拡散されるため、レンズ部39からの光度の強い輝線は発生せず、セード14の光透過領域46に輝度むらが生じるのを防止できる。   Further, as shown in FIG. 2, a part of the light incident on the lens unit 39 from the light emitting element 30 is reflected by the emission surface 39 b and travels toward the back side of the lens unit 39. The light diffusion part 41 is formed in the area on the back side of the lens part 39, but if it is not formed, the light is reflected on the back side of the cover part 36, which is the area on the back side of the lens part 39. However, when this light is emitted from the lens unit 39, a bright line is generated, and when this bright line is reflected in the light transmission region 46 of the shade 14, uneven brightness occurs in the light transmission region 46 of the shade 14. . On the other hand, since the light diffusion part 41 is formed in the area on the back side of the lens part 39, the light directed toward the back side of the lens part 39 is diffused by the light diffusion part 41. A bright line having a high luminous intensity is not generated, and uneven brightness in the light transmission region 46 of the shade 14 can be prevented.

また、点灯時に複数の発光素子30が発生する熱は、基板29から器具本体11に熱伝導され、器具本体11から効率よく放熱される。一方、点灯装置が発生する熱は、上面カバー16に伝わり、上面カバー16から効率よく放熱される。そのため、発光素子30が発生する熱と点灯装置が発生する熱とが干渉し合うことが少なく、それぞれが発生する熱を効率よく放熱することができる。   Further, the heat generated by the plurality of light emitting elements 30 at the time of lighting is conducted from the substrate 29 to the instrument body 11, and is efficiently radiated from the instrument body 11. On the other hand, the heat generated by the lighting device is transferred to the upper cover 16 and is efficiently radiated from the upper cover 16. Therefore, the heat generated by the light emitting element 30 and the heat generated by the lighting device are unlikely to interfere with each other, and the heat generated by each can be efficiently radiated.

このように本実施形態の照明器具10では、透光カバー13に発光素子30から出射される光を器具本体11の中央側および周辺側に広がる配光に制御するレンズ部39を設けることにより、セード14の中央部や周辺部の領域でも高透過率部47を通じた光のきらめき感による演出効果を向上でき、しかも、発光モジュール12に対向する透光カバー13の覆い部36の面でかつレンズ部39の領域に光拡散部41を形成することにより、レンズ部39から出射される輝線がセード14の光透過領域46に映ってその光透過領域46に輝度むらが生じるのを低減することができる。   As described above, in the lighting fixture 10 of the present embodiment, the light transmitting element 13 is provided with the lens unit 39 that controls the light emitted from the light emitting element 30 so as to spread the light to the center side and the peripheral side of the fixture body 11. Even in the central and peripheral areas of the shade 14, the effect of glittering light through the high transmittance part 47 can be improved, and the surface of the cover part 36 of the transparent cover 13 facing the light emitting module 12 and the lens By forming the light diffusion part 41 in the region of the part 39, it is possible to reduce the occurrence of uneven brightness in the light transmission region 46 due to the bright line emitted from the lens part 39 being reflected in the light transmission region 46 of the shade 14. it can.

また、透光カバー13のレンズ部39が環状方向である周方向に同じ断面形状に形成されているため、透光カバー13が器具本体11に対して回動させることによって着脱する取付構造を採用していても、着脱時にレンズ部39と発光素子30と干渉するのを防止できる。   In addition, since the lens portion 39 of the translucent cover 13 is formed in the same cross-sectional shape in the circumferential direction that is an annular direction, an installation structure that allows the translucent cover 13 to be attached and detached by rotating with respect to the instrument body 11 is adopted. Even if it does, it can prevent interfering with the lens part 39 and the light emitting element 30 at the time of attachment or detachment.
