Description

本発明は、固体発光素子を光源とする照明器具に関する。   The present invention relates to a lighting fixture using a solid light emitting element as a light source.

従来、発光ダイオードなどの固体発光素子を光源とする照明器具や照明装置が種種提供されている。例えば、特許文献１には製品の外観検査に用いられる照明装置が記載されている。この従来例は、複数の発光ダイオードが実装された基板と、一面で基板と接触する放熱部材と、放熱部材を保持するハウジングとを備えている。基板の取付孔に挿通されたボルトが放熱部材のねじ孔に螺合されることで基板と放熱部材が密着し、発光ダイオードの発する熱が放熱部材から放熱されるようになっている。   2. Description of the Related Art Various types of lighting fixtures and lighting devices that use a solid light emitting element such as a light emitting diode as a light source have been provided. For example, Patent Document 1 describes an illumination device used for appearance inspection of products. This conventional example includes a substrate on which a plurality of light emitting diodes are mounted, a heat dissipation member that contacts the substrate on one side, and a housing that holds the heat dissipation member. The bolt inserted into the mounting hole of the board is screwed into the screw hole of the heat radiating member so that the board and the heat radiating member come into close contact with each other, and heat generated by the light emitting diode is radiated from the heat radiating member.

しかしながら、特許文献１記載の従来例のように基板と放熱部材がねじ止めされる構成では、基板と放熱部材との密着度を高めるためには多数のねじ(ボルト)が必要となり、部品点数の増加によるコストの上昇や交換時の作業性低下といった問題が生じる。また、板バネと放熱部材との間に基板を挟持させることで基板と放熱部材の密着度を高めることも考えられるが、この場合、板バネが露出して外観の見栄えが良くないといった問題がある。   However, in the configuration in which the board and the heat radiating member are screwed as in the conventional example described in Patent Document 1, a large number of screws (bolts) are required to increase the adhesion between the board and the heat radiating member. Problems such as an increase in cost due to the increase and a decrease in workability during replacement occur. In addition, it is conceivable to increase the adhesion between the substrate and the heat dissipation member by sandwiching the substrate between the leaf spring and the heat dissipation member.

以下、固体発光素子に発光ダイオード(LED)を用いた照明器具に本発明の技術思想を適用した実施形態について説明する。ただし、固体発光素子はLEDに限定されるものではなく、例えば、有機ＥＬ素子などのLED以外の固体発光素子を用いる照明器具にも本発明の技術思想が適用可能である。   Hereinafter, an embodiment in which the technical idea of the present invention is applied to a lighting apparatus using a light emitting diode (LED) as a solid light emitting element will be described. However, the solid-state light-emitting element is not limited to the LED, and the technical idea of the present invention can be applied to, for example, a lighting fixture that uses a solid-state light-emitting element other than an LED, such as an organic EL element.

(実施形態１)
本実施形態の照明器具は、図１及び図２に示すように光源ユニット１、器具本体２、一対の外郭(固定部材)３を備える。光源ユニット１は、長尺の矩形平板形状に形成されている基板11と、基板11の表面(上面)に長手方向に一列に並べて実装される複数の発光ダイオード10とで構成されている。 (Embodiment 1)
The lighting fixture of this embodiment is provided with the light source unit 1, the fixture main body 2, and a pair of outer shells (fixing member) 3, as shown in FIG.1 and FIG.2. The light source unit 1 includes a substrate 11 formed in a long rectangular flat plate shape, and a plurality of light emitting diodes 10 mounted in a line in the longitudinal direction on the surface (upper surface) of the substrate 11.

器具本体２は、長尺の矩形平板状である本体部20及び本体部20の長手方向に沿った両端に設けられる一対の支持部21とがアルミの押出成形によって一体に形成されている。ただし、本体部20の背面(下面)側には、複数の放熱フィン22が等間隔に並ぶようにして本体部20と一体に形成されている。つまり、本実施形態では本体部20と放熱フィン22が放熱部材に相当する。なお、図２では一部の放熱フィン22の図示を省略している。そして、本体部20の一面(上面)側に光源ユニット１が配置され、発光ダイオード10から放射される熱が基板11から本体部20及び放熱フィン22に伝導されて放熱される。また、支持部21は、本体部20に繋がる縦片210と、縦片210の上端より本体部20と平行に突出する横片211とを有している。   In the instrument body 2, a main body portion 20 having a long rectangular flat plate shape and a pair of support portions 21 provided at both ends along the longitudinal direction of the main body portion 20 are integrally formed by extrusion molding of aluminum. However, a plurality of heat radiation fins 22 are formed integrally with the main body 20 on the back surface (lower surface) side of the main body 20 so as to be arranged at equal intervals. That is, in the present embodiment, the main body 20 and the heat radiating fins 22 correspond to heat radiating members. In FIG. 2, illustration of some of the heat radiation fins 22 is omitted. The light source unit 1 is disposed on the one surface (upper surface) side of the main body 20, and heat radiated from the light emitting diode 10 is conducted from the substrate 11 to the main body 20 and the heat radiating fins 22 to be radiated. In addition, the support portion 21 includes a vertical piece 210 connected to the main body portion 20 and a horizontal piece 211 that protrudes in parallel with the main body portion 20 from the upper end of the vertical piece 210.

外郭３は、発光ダイオード10から放射される光を前方(上方)に反射する反射板30と、器具本体２の支持部21に取り付けられる取付部31と、器具本体２との間で弾性力により基板11を挟持する挟持部32とがアルミの押出成形によって一体に形成されている。ただし、器具本体２及び外郭３を形成する材料はアルミに限定されるものでなく、熱伝導度が相対的に高い金属材料であればよい。   The outer shell 3 is elastically coupled between the reflector body 30 that reflects the light emitted from the light emitting diode 10 forward (upward), the attachment part 31 attached to the support part 21 of the instrument body 2, and the instrument body 2. A sandwiching portion 32 that sandwiches the substrate 11 is integrally formed by extrusion molding of aluminum. However, the material which forms the instrument main body 2 and the outer shell 3 is not limited to aluminum, and may be a metal material having a relatively high thermal conductivity.

取付部31は、一端が反射板30の一端(上端)に繋がる上横片310と、一端(上端)が上横片310の他端に繋がる縦片311と、縦片311の他端(下端)から上横片310と平行に突出する下横片312とを有し、全体が略鈎形に形成されている。なお、下横片312の先端には上向きに突出する突片313が一体に形成されている。   The attachment portion 31 has an upper horizontal piece 310 whose one end is connected to one end (upper end) of the reflector 30, a vertical piece 311 whose one end (upper end) is connected to the other end of the upper horizontal piece 310, and the other end (lower end) of the vertical piece 311. ) To the upper horizontal piece 310 and the lower horizontal piece 312 protruding in parallel, and the whole is formed in a substantially bowl shape. A protruding piece 313 protruding upward is integrally formed at the tip of the lower horizontal piece 312.

反射板30は、先端(下端)が発光ダイオード10の近傍に位置するように斜め下向きに傾斜しており、その表面(上面)が反射面となっている。つまり、発光ダイオード10の光が反射板30の反射面に反射されて光源ユニット１の前方(上方)へ照射される。挟持部32は、反射板30の非反射面(下面)側から上横片310と平行に突出する薄板状の弾性片320と、弾性片320の先端に設けられた略楕円柱形状の当接部321とを有している。   The reflecting plate 30 is inclined obliquely downward so that the tip (lower end) is positioned in the vicinity of the light emitting diode 10, and the surface (upper surface) is a reflecting surface. That is, the light of the light emitting diode 10 is reflected by the reflecting surface of the reflecting plate 30 and is irradiated forward (upward) of the light source unit 1. The sandwiching portion 32 includes a thin plate-like elastic piece 320 protruding in parallel with the upper horizontal piece 310 from the non-reflecting surface (lower surface) side of the reflecting plate 30, and a substantially elliptical columnar contact provided at the tip of the elastic piece 320 Part 321.

次に、本実施形態の照明器具の組立手順を説明する。まず、器具本体２の短手方向(左右方向)の両側にそれぞれ外郭３が取り付けられる。具体的には、反射板30が本体部20と対向する向きで、上横片310と挟持部32の間に横片211を挿入するように器具本体２の長手方向に沿って外郭３をスライドさせれば、図１(ｂ)に示すように器具本体２の短手方向の両側にそれぞれ外郭３を仮固定することができる。そして、反射板30と本体部20の隙間に基板11を挿入するように、器具本体２の長手方向に沿って光源ユニット１をスライドさせれば、図１(ｃ)に示すように器具本体２に光源ユニット１が取り付けられる。最後に、各外郭３を器具本体２の短手方向に沿ってスライドさせると、突片313の傾斜面313Aに縦片210の下端が当接して下横片312が下向きに撓み、突片313が下横片312を乗り越えて外郭３が器具本体２に取り付けられる(図１(ａ)参照)。なお、突片313が下横片312を乗り越えて係合することで器具本体２に対して外郭３が抜け止めされる。また、外郭３を器具本体２の短手方向に沿ってスライドさせると、当接部321と本体部20の間に基板11が挿入され、当接部321が基板11に乗り上げる。そして、当接部321が基板11に乗り上げると弾性片320が本体部20から離れる向き(上向き)に撓むので、弾性片320の復元力(弾性力)によって挟持部32と本体部20の間に基板11が挟持される。このとき、弾性片320の弾性力で基板11の下面と本体部20の上面とが密着するため、基板11から本体部20への熱伝導性を向上することができる。   Next, the assembly procedure of the lighting fixture of this embodiment is demonstrated. First, the outer shells 3 are attached to both sides of the instrument body 2 in the short direction (left-right direction). Specifically, the outer shell 3 is slid along the longitudinal direction of the instrument main body 2 so that the horizontal piece 211 is inserted between the upper horizontal piece 310 and the sandwiching portion 32 with the reflecting plate 30 facing the main body portion 20. Then, as shown in FIG. 1B, the outer shells 3 can be temporarily fixed on both sides of the instrument body 2 in the short direction. Then, if the light source unit 1 is slid along the longitudinal direction of the instrument body 2 so that the substrate 11 is inserted into the gap between the reflector 30 and the body part 20, the instrument body 2 as shown in FIG. The light source unit 1 is attached to the. Finally, when each outer shell 3 is slid along the lateral direction of the instrument body 2, the lower end of the vertical piece 210 comes into contact with the inclined surface 313 A of the protruding piece 313, and the lower horizontal piece 312 bends downward. Gets over the lower horizontal piece 312 and the outer shell 3 is attached to the instrument body 2 (see FIG. 1A). In addition, the outer shell 3 is prevented from being detached from the instrument body 2 by the projecting piece 313 getting over and engaging the lower horizontal piece 312. When the outer shell 3 is slid along the lateral direction of the instrument main body 2, the substrate 11 is inserted between the contact portion 321 and the main body portion 20, and the contact portion 321 rides on the substrate 11. When the abutting portion 321 rides on the substrate 11, the elastic piece 320 bends in a direction away from the main body portion 20 (upward), so that the restoring force (elastic force) of the elastic piece 320 causes a gap between the sandwiching portion 32 and the main body portion 20. The substrate 11 is held between the two. At this time, since the lower surface of the substrate 11 and the upper surface of the main body portion 20 are in close contact with each other by the elastic force of the elastic piece 320, the thermal conductivity from the substrate 11 to the main body portion 20 can be improved.

上述のように本実施形態では、基板11を放熱フィン22に固定する固定部材(外郭３)が、反射板30と、器具本体３に取り付けられる取付部31と、反射板30の非反射面側に設けられて器具本体２との間で弾性力により基板11を挟持する挟持部32とが一体に構成されている。このため、基板11と放熱フィン22(本体部20)を固定するためのねじが不要になるとともに、挟持部32の弾性力によって基板11と放熱フィン22(本体部20)との密着性が確保でき、さらに挟持部32を反射板30の背後に隠すことができる。その結果、従来例に比べて、部品点数の増加や外観の見栄えの低下を抑えつつ放熱性の向上を図ることができる。   As described above, in this embodiment, the fixing member (outer shell 3) for fixing the substrate 11 to the heat radiating fins 22 is the reflecting plate 30, the mounting portion 31 attached to the instrument body 3, and the non-reflecting surface side of the reflecting plate 30 And a sandwiching portion 32 that sandwiches the substrate 11 by elastic force between the instrument body 2 and the instrument body 2 is integrally formed. This eliminates the need for screws for fixing the substrate 11 and the radiation fin 22 (main body portion 20), and ensures the adhesion between the substrate 11 and the radiation fin 22 (main body portion 20) by the elastic force of the clamping portion 32. In addition, the clamping portion 32 can be hidden behind the reflector 30. As a result, it is possible to improve heat dissipation while suppressing an increase in the number of parts and a decrease in the appearance of the appearance as compared with the conventional example.

また本実施形態では、固定部材(外郭３)が、器具本体２の短手方向における一端側に取り付けられる第１固定部材(左側の外郭３)と、器具本体２の短手方向における他端側に取り付けられる第２固定部材(右側の外郭３)とからなる。そして、第１及び第２固定部材(一対の外郭３)は、挟持部３２が基板11を挟持しない位置(図１(ｂ)に示す仮固定状態の位置)と基板11を挟持する位置(図１(ａ)に示す本固定状態の位置)との間でスライド自在であるので、ドライバなどの工具を使わずに容易に組立できる。   In the present embodiment, the fixing member (outer shell 3) is attached to one end side in the short direction of the instrument body 2 and the other end side in the short direction of the instrument body 2. And a second fixing member (right outer shell 3) attached to the head. The first and second fixing members (the pair of outer shells 3) are located at a position where the holding portion 32 does not hold the substrate 11 (a position in the temporarily fixed state shown in FIG. 1B) and a position where the substrate 11 is held (see FIG. 1). 1 (a), which is slidable between the positions of the main fixed state), and can be easily assembled without using a tool such as a screwdriver.

(実施形態２)
本実施形態の照明器具は、第１及び第２固定部材(一対の外郭３)が仮固定状態の位置と本固定状態の位置との間で回動自在である点に特徴があり、図３に示すように実施形態１とほぼ共通の構成を有している。したがって、実施形態１と共通の構成要素には同一の符号を付して説明を省略する。 (Embodiment 2)
The lighting fixture of the present embodiment is characterized in that the first and second fixing members (the pair of outer shells 3) are rotatable between a temporarily fixed position and a fully fixed position. As shown in FIG. 4, the configuration is almost the same as that of the first embodiment. Therefore, the same components as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

器具本体２は、支持部21がない点、本体部20の上面に光源ユニット１の基板11と嵌合する嵌合溝200が設けられた点、支持部21の代わりに本体部20の両端から長手方向に沿って下向きに突出する突部201が設けられた点、以外の構成は実施形態１と共通である。また外郭３は、反射板30の先端(下端)が光源ユニット１の基板11の表面に接触しない程度の長さに設定されており(図３(ａ)参照)、その他の構成は実施形態１と共通である。   The instrument main body 2 has no support portion 21, has a fitting groove 200 that fits the substrate 11 of the light source unit 1 on the upper surface of the main body portion 20, and from both ends of the main body portion 20 instead of the support portion 21. The configuration is the same as that of the first embodiment except that a protrusion 201 protruding downward along the longitudinal direction is provided. The outer shell 3 is set to such a length that the tip (lower end) of the reflecting plate 30 does not come into contact with the surface of the substrate 11 of the light source unit 1 (see FIG. 3 (a)). And in common.

次に、本実施形態の照明器具の組立手順を説明する。まず、器具本体２の本体部20の嵌合溝200に光源ユニット１の基板11が嵌合される。そして、図３(ｂ)に示すように基板11の表面(上面)に当接させた反射板30の先端(下端)を支点にして、下横片312が本体部20に近付く向きに外郭３を回動すると、突片313の傾斜面313Aと突部201の傾斜面201Aが当接して取付部31が反回動向きに撓み、突片313が突部201を乗り越えて外郭３が器具本体２に取り付けられる(図３(ａ)参照)。そして、突片313が突部201を乗り越えて係合することで器具本体２に対して外郭３が抜け止めされる。このとき、当接部321が基板11の表面(上面)に当接して弾性片320が本体部20から離れる向き(上向き)に撓むので、弾性片320の復元力(弾性力)によって挟持部32と本体部20の間に基板11が挟持される。   Next, the assembly procedure of the lighting fixture of this embodiment is demonstrated. First, the substrate 11 of the light source unit 1 is fitted into the fitting groove 200 of the main body 20 of the instrument main body 2. Then, as shown in FIG. 3B, the outer shell 312 is oriented so that the lower horizontal piece 312 approaches the main body 20 with the tip (lower end) of the reflector 30 in contact with the surface (upper surface) of the substrate 11 as a fulcrum. Is rotated, the inclined surface 313A of the protruding piece 313 and the inclined surface 201A of the protruding portion 201 come into contact with each other, the mounting portion 31 bends in the counter-rotating direction, the protruding piece 313 gets over the protruding portion 201, and the outer shell 3 is the instrument body. 2 (see FIG. 3A). Then, the outer shell 3 is prevented from coming off from the instrument body 2 by the projecting piece 313 getting over and engaging the projecting portion 201. At this time, since the contact portion 321 contacts the surface (upper surface) of the substrate 11 and the elastic piece 320 bends in a direction away from the main body portion 20 (upward), the holding portion is held by the restoring force (elastic force) of the elastic piece 320. The substrate 11 is sandwiched between the body 32 and the main body 20.

上述のように本実施形態においても実施形態１と同様に、基板11と放熱フィン22(本体部20)を固定するためのねじが不要になり、挟持部32の弾性力によって基板11と放熱フィン22(本体部20)との密着性が確保でき、さらに挟持部32を反射板30の背後に隠すことができる。その結果、従来例に比べて、部品点数の増加や外観の見栄えの低下を抑えつつ放熱性の向上を図ることができる。しかも、第１及び第２固定部材(一対の外郭３)は、挟持部３２が基板11を挟持しない位置(図３(ｂ)に示す仮固定状態の位置)と基板11を挟持する位置(図３(ａ)に示す本固定状態の位置)との間で回動自在であるので、ドライバなどの工具を使わずに容易に組立できる。   As described above, also in the present embodiment, as in the first embodiment, a screw for fixing the substrate 11 and the radiation fin 22 (main body portion 20) is not necessary, and the substrate 11 and the radiation fin are caused by the elastic force of the clamping portion 32. Adhesion with 22 (main body portion 20) can be ensured, and the clamping portion 32 can be hidden behind the reflector 30. As a result, it is possible to improve heat dissipation while suppressing an increase in the number of parts and a decrease in the appearance of the appearance as compared with the conventional example. Moreover, the first and second fixing members (the pair of outer shells 3) are located at a position where the holding portion 32 does not hold the substrate 11 (a position in the temporarily fixed state shown in FIG. 3B) and a position where the substrate 11 is held (see FIG. 3). 3 (a), and can be easily assembled without using a tool such as a screwdriver.
