ところで、ＬＥＤを実装した実装基板を灯具の前面に取り付ける際に、実装基板が嵌合する凹部を設ける場合がある。この場合、凹部を形成する金型の摩耗により、凹部の底面角部にＲ部が発生するのを考慮して、Ｒ部が実装基板に当たらないように凹部を大きめに形成して、ねじで固定するのが一般的である。
しかしながら、凹部が実装基板よりも大きめに形成されているため、位置決め精度が低下する。また、ねじの締め付けトルク管理を徹底して、実装基板に与える応力と灯具への放熱効果を得るための密接さを管理しなければならないため、組立作業性が悪くなるという問題があった。 By the way, when mounting the mounting substrate on which the LED is mounted on the front surface of the lamp, there is a case where a recess into which the mounting substrate is fitted may be provided. In this case, considering that the R portion is generated at the bottom corner of the recess due to wear of the mold forming the recess, the recess is formed large so that the R portion does not hit the mounting substrate, and is It is common to fix.
However, since the recess is formed larger than the mounting substrate, the positioning accuracy is lowered. In addition, since the tightening torque management of the screws must be thoroughly performed to manage the stress applied to the mounting board and the closeness for obtaining the heat radiation effect to the lamp, there is a problem that the assembling workability is deteriorated.

本発明は、従来の問題を解決するためになされたもので、ＬＥＤを実装した実装基板を、灯具に対して容易に位置決めするとともに密着させて、組立作業性および放熱効果を改善させることができるＬＥＤ照明器具を提供することを目的とする。   The present invention has been made in order to solve the conventional problems, and the mounting substrate on which the LED is mounted can be easily positioned and brought into close contact with the lamp, thereby improving the assembly workability and the heat dissipation effect. An object is to provide an LED lighting apparatus.

本発明のＬＥＤ照明器具は、実装基板にＬＥＤを実装したＬＥＤ光源と、前記ＬＥＤ光源を取り付ける取付面を有する灯具と、を備え、前記取付面に、前記実装基板を嵌め込む嵌合凹部を設けるとともに、前記嵌合凹部の内周壁が前記実装基板の側端面に当接する位置には、前記嵌合凹部の前記内周壁に連続する底面に窪みを設けたものである。   The LED lighting apparatus of the present invention includes an LED light source in which an LED is mounted on a mounting board, and a lamp having a mounting surface to which the LED light source is mounted, and a fitting recess for fitting the mounting board is provided on the mounting surface. In addition, a recess is provided on the bottom surface of the fitting recess that is continuous with the inner peripheral wall at a position where the inner peripheral wall of the fitting recess contacts the side end surface of the mounting substrate.

また、本発明のＬＥＤ照明器具は、前記嵌合凹部の前記内周壁に、前記嵌合凹部に嵌め込まれた前記実装基板の前記側端面に当接する複数個の凸部を設けたものである。   Moreover, the LED lighting fixture of this invention provides the some convex part contact | abutted to the said side end surface of the said mounting board | substrate inserted by the said fitting recessed part in the said inner peripheral wall of the said fitting recessed part.

さらに、本発明のＬＥＤ照明器具は、前記凸部が、前記実装基板を囲む位置に３個以上設けられたものである。   Furthermore, in the LED lighting apparatus of the present invention, three or more of the convex portions are provided at positions surrounding the mounting substrate.

本発明は、ＬＥＤを実装した実装基板を嵌合させる嵌合凹部の内周壁が、実装基板の側端面に当接する位置には、内周壁に連続する嵌合凹部の底面に窪みを設けたので、嵌合凹部の形成時に金型の摩耗により生じるＲ部は、実装基板に当接しない。これにより、実装基板を灯具に対して容易に位置決めするとともに密着させることができ、組立作業性および放熱効果を改善させることができるという効果を有するＬＥＤ照明器具を提供できる。   In the present invention, since the inner peripheral wall of the fitting recess for fitting the mounting substrate on which the LED is mounted is in contact with the side end surface of the mounting substrate, a recess is provided on the bottom surface of the fitting recess that is continuous with the inner peripheral wall. The R portion generated by the wear of the mold when forming the fitting recess does not contact the mounting substrate. Thereby, the mounting board can be easily positioned and brought into close contact with the lamp, and an LED lighting apparatus can be provided that has the effect of improving the assembly workability and the heat dissipation effect.

図３（Ａ）に示すように、灯具本体２２の下面２２１には、複数個のＬＥＤ光源２１が取り付けられる。
図３（Ｂ）に示すように、ＬＥＤ光源２１は、ＬＥＤ２１１と、ＬＥＤ２１１を実装する実装基板２１２を有する。また、実装基板２１２には、コネクタ２１３が取り付けられている。 As shown in FIG. 3A, a plurality of LED light sources 21 are attached to the lower surface 221 of the lamp body 22.
As shown in FIG. 3B, the LED light source 21 includes an LED 211 and a mounting substrate 212 on which the LED 211 is mounted. A connector 213 is attached to the mounting board 212.

図４（Ａ）に示すように、灯具本体２２の下面２２１には、ＬＥＤ光源２１用の嵌合凹部３１が、周方向に所定間隔で、下面２２１の中心ＣＰから放射状に設けられている。実装基板２１２は、嵌合凹部３１の底面３１２に密着して取り付けられる。
図４（Ｂ）に示すように、嵌合凹部３１は、ＬＥＤ光源２１の実装基板２１２の大きさおよび形状よりも若干大きめに形成されている。嵌合凹部３１の内周壁３１１には、少なくとも３個（ここでは、例えば５個）の凸部３２が、嵌合凹部３１の内側に突出して設けられている。
なお、凸部３２の位置に対応する底面３１２には、各々窪み３１３が設けられている。 As shown in FIG. 4A, fitting recesses 31 for the LED light source 21 are provided radially on the lower surface 221 of the lamp body 22 from the center CP of the lower surface 221 at predetermined intervals in the circumferential direction. The mounting substrate 212 is attached in close contact with the bottom surface 312 of the fitting recess 31.
As shown in FIG. 4B, the fitting recess 31 is formed to be slightly larger than the size and shape of the mounting substrate 212 of the LED light source 21. On the inner peripheral wall 311 of the fitting concave portion 31, at least three (here, for example, five) convex portions 32 are provided so as to protrude inside the fitting concave portion 31.
Each bottom surface 312 corresponding to the position of the convex portion 32 is provided with a recess 313.

図５（Ａ）に示すように、凸部３２の先端面は、嵌合凹部３１に嵌めるＬＥＤ光源２１の実装基板２１２の大きさに略対応しており、実装基板２１２の側端面２１５に当接する。
図５（Ｂ）に示すように、凸部３２位置においては、窪み３１３が設けられているので、実装基板２１２の上面角部２１４は嵌合凹部３１の底面３１２に当接しない。また、凸部３２位置以外の位置においては、嵌合凹部３１が実装基板２１２よりも大きく形成されているため、実装基板２１２の上面角部２１４は、嵌合凹部３１の底面３１２と内周壁３１１との交点である底面角部３１４に接触せずに、底面３１２に接触する。
従って、実装基板２１２の上面角部２１４は、金型の摩耗により形成時にＲ状になるおそれがある嵌合凹部３１の底面角部３１４に当接しない。 As shown in FIG. 5A, the front end surface of the convex portion 32 substantially corresponds to the size of the mounting substrate 212 of the LED light source 21 fitted in the fitting concave portion 31, and contacts the side end surface 215 of the mounting substrate 212. Touch.
As shown in FIG. 5B, since the recess 313 is provided at the position of the convex portion 32, the upper surface corner portion 214 of the mounting substrate 212 does not contact the bottom surface 312 of the fitting concave portion 31. Further, since the fitting recess 31 is formed larger than the mounting substrate 212 at a position other than the convex portion 32 position, the upper surface corner 214 of the mounting substrate 212 has the bottom surface 312 and the inner peripheral wall 311 of the fitting recess 31. The bottom surface 312 is contacted without contacting the bottom surface corner 314 that is the intersection with the bottom surface 312.
Therefore, the upper surface corner portion 214 of the mounting substrate 212 does not contact the bottom surface corner portion 314 of the fitting concave portion 31 that may be rounded when formed due to wear of the mold.

図６（Ａ）および（Ｂ）に示すように、嵌合凹部３１に嵌め込まれたＬＥＤ光源２１は、実装基板２１２をばね部材３３で押えて固定する。
ばね部材３３は、灯具本体２２の下面２２１において、嵌合凹部３１が設けられていない部位に固定するための支持部３３１と、この支持部３３１を連結する連結部３３２を有する。支持部３３１には、実装基板２１２を灯具本体２２の下面２２１に押し付ける押圧ばね部３３３を有する。 As shown in FIGS. 6A and 6B, the LED light source 21 fitted in the fitting recess 31 presses and fixes the mounting substrate 212 with a spring member 33.
The spring member 33 has a support portion 331 for fixing to a portion where the fitting recess 31 is not provided on the lower surface 221 of the lamp body 22 and a connecting portion 332 for connecting the support portion 331. The support portion 331 includes a pressing spring portion 333 that presses the mounting substrate 212 against the lower surface 221 of the lamp body 22.

従って、ＬＥＤ光源２１の取付けは、まず、ＬＥＤ光源２１の実装基板２１２を、灯具本体２２の下面２２１に設けられている嵌合凹部３１に嵌め込む。このとき、嵌合凹部３１の凸部３２により実装基板２１２の位置決めをする。
次いで、取付ねじ３４を、ばね部材３３の支持部３３１に設けられている貫通孔３３４に通し、さらに、灯具本体２２下面２２１のねじ孔２２２に締結する。
これにより、ばね部材３３の押圧ばね部３３３が実装基板２１２を灯具本体２２の下面２２１に押し付けて固定する。 Therefore, the LED light source 21 is attached by first fitting the mounting substrate 212 of the LED light source 21 into the fitting recess 31 provided on the lower surface 221 of the lamp body 22. At this time, the mounting substrate 212 is positioned by the convex portion 32 of the fitting concave portion 31.
Next, the mounting screw 34 is passed through the through hole 334 provided in the support portion 331 of the spring member 33, and further fastened to the screw hole 222 on the lower surface 221 of the lamp body 22.
Accordingly, the pressing spring portion 333 of the spring member 33 presses and fixes the mounting substrate 212 to the lower surface 221 of the lamp body 22.

以上、説明した本発明に係る実施形態のＬＥＤ照明器具１０によれば、ＬＥＤ２１１を実装した実装基板２１２を、灯具２０の下面２２１に設けられた嵌合凹部３１に嵌合させて取り付ける。
このとき、嵌合凹部３１の内周壁３１１が実装基板２１２の側端面２１５に当接する位置には、嵌合凹部３１の内周壁３１１に連続する底面３１２に窪み３１３を設けたので、嵌合凹部３１の形成時に金型の摩耗により生じるＲ部は、実装基板２１２に当接しない。
これにより、実装基板２１２を灯具本体２２に対して容易に位置決めするとともに密着させることができ、組立作業性および放熱効果を改善させることができる。 As described above, according to the LED lighting apparatus 10 according to the embodiment of the present invention described above, the mounting substrate 212 on which the LED 211 is mounted is fitted to the fitting recess 31 provided on the lower surface 221 of the lamp 20 and attached.
At this time, since the recess 313 is provided on the bottom surface 312 continuous with the inner peripheral wall 311 of the fitting recess 31 at a position where the inner peripheral wall 311 of the fitting recess 31 contacts the side end surface 215 of the mounting substrate 212, the fitting recess The R portion generated by the wear of the mold when forming 31 does not contact the mounting substrate 212.
Thereby, the mounting substrate 212 can be easily positioned and brought into close contact with the lamp main body 22, and the assembling workability and the heat dissipation effect can be improved.

また、嵌合凹部３１の内周壁３１１に、嵌合凹部３１に嵌め込まれた実装基板２１２の側端面２１５に当接する複数個の凸部３２を設けたので、実装基板２１２を容易に位置決めできる。   Further, since the plurality of convex portions 32 that contact the side end face 215 of the mounting substrate 212 fitted in the fitting concave portion 31 are provided on the inner peripheral wall 311 of the fitting concave portion 31, the mounting substrate 212 can be easily positioned.

さらに、凸部３２を、実装基板２１２を囲む位置に３個以上設けたので、実装基板２１２を、嵌合凹部３１内に確実に位置決めできる。   Furthermore, since three or more convex portions 32 are provided at a position surrounding the mounting substrate 212, the mounting substrate 212 can be reliably positioned in the fitting recess 31.

なお、本発明のＬＥＤ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、実装基板２１２の側端面２１５に当接する嵌合凹部３１の内周壁３１１として、複数の凸部３２を設けた場合について例示した。
このほか、図７に示すように、嵌合凹部３１Ｂの内周壁３１１が全面にわたって実装基板２１２の側端面２１５と当接する場合には、内周壁３１１に連続する底面３１２に、連続した溝状の窪み３１３Ｂを設ける。 In addition, the LED lighting fixture of this invention is not limited to embodiment mentioned above, A suitable deformation | transformation, improvement, etc. are possible.
