Description

本発明の実施形態は、例えば、ＬＥＤや有機ＥＬを光源とした発光部を有した電球形ランプ及び照明器具に関する。   Embodiments of the present invention relate to, for example, a light bulb shaped lamp and a lighting fixture having a light emitting unit that uses an LED or an organic EL as a light source.

発光部を有する発光モジュールを用いた電球形ランプとして、複数個のＬＥＤからなるＬＥＤモジュールで光源部を構成し、このＬＥＤモジュールを筐体に取り付けカバーで覆って外観を白熱電球形状に形成したＬＥＤ電球が知られている。このようなＬＥＤ電球では、カバーの反対側の筐体にケースを取り付け、そのケースの内部に点灯回路を収納するとともにケースの端部に口金を設けている。   As a light bulb shaped lamp using a light emitting module having a light emitting part, a light source part is constituted by an LED module composed of a plurality of LEDs, and this LED module is attached to a housing and covered with a cover so that the appearance is an incandescent light bulb shape A light bulb is known. In such an LED bulb, a case is attached to a housing on the opposite side of the cover, a lighting circuit is housed inside the case, and a base is provided at the end of the case.

発光部であるＬＥＤや点灯回路は発熱するので、その熱をＬＥＤ電球の外部へ放出するために筐体に放熱フィンが設けてられており、通常、この放熱フィンは見栄えを考慮して等ピッチ間隔で放射状に配列されている。これらの放熱フィンは金属成型などにより形成されている。   Since the LED and lighting circuit, which are light emitting parts, generate heat, heat radiating fins are provided in the housing in order to release the heat to the outside of the LED bulbs. They are arranged radially at intervals. These radiating fins are formed by metal molding or the like.

ＬＥＤ電球として、ＬＥＤモジュールのＬＥＤから発生する熱のほとんどを放熱部の放熱フィンで放熱し点灯回路の温度上昇を抑え、部品コストを上昇させずに点灯回路の寿命を維持できるようにしたものがある（例えば、特許文献１参照）。   As an LED light bulb, most of the heat generated from the LED of the LED module is radiated by the heat radiating fins of the heat radiating part to suppress the temperature rise of the lighting circuit and to maintain the life of the lighting circuit without increasing the component cost Yes (for example, see Patent Document 1)

特開２０１０−５６０５９号公報JP 2010-56059 A

しかし、筐体に設けられる放熱フィンは、金属成型などにより等ピッチ間隔で放射状に形成されるので回転対称であり、筐体を回転させても基準となる部分ない。従って、この筐体に部品を取り付ける際に、その部品の取付位置を確認するための基準がないことになり自動組立が困難となる。そこで、自動組立の都合上、筐体の外観の見えやすい位置に目印を施すことが考えられるが、その目印として、凹部、凸部、穴などとした場合には、筐体の見栄えが悪くなり、デザイン上からその採用は困難である。   However, the heat dissipating fins provided in the casing are rotationally symmetric because they are formed radially at equal pitch intervals by metal molding or the like, and there is no reference portion even if the casing is rotated. Therefore, when a part is attached to the housing, there is no reference for confirming the attachment position of the part, and automatic assembly becomes difficult. Therefore, for the convenience of automatic assembly, it is conceivable to place a mark at a position where the external appearance of the housing is easy to see. However, if the concave portion, convex portion, hole or the like is used as the mark, the appearance of the housing will deteriorate. From the design point of view, it is difficult to adopt.

そこで、組立開始から組立完了まで一貫して筐体の基準となる位置を容易に把握でき、しかも筐体の外面の見栄えにもほとんど悪影響を与えない電球形ランプ及び照明器具を提供する。   Accordingly, there is provided a light bulb shaped lamp and a lighting apparatus that can easily grasp the position serving as a reference of the casing consistently from the start of assembly to the completion of assembly and that have little adverse effect on the appearance of the outer surface of the casing.

本発明の実施形態によれば、発光部を有する発光モジュールと；一方側に前記発光モジュール、他方側に口金が設けられた筐体と；前記筐体の外面に形成され前記筐体の基準位置を示す位置決め部と、前記発光モジュールを覆って前記発光部からの放射光を外部に出射するカバーと；前記発光部を点灯する点灯回路と；を備える。   According to an embodiment of the present invention, a light emitting module having a light emitting unit; a housing provided with the light emitting module on one side and a base on the other side; a reference position of the housing formed on the outer surface of the housing A positioning portion that covers the light emitting module, and a cover that emits the emitted light from the light emitting portion to the outside; a lighting circuit that lights the light emitting portion.

本発明によれば、自動組立を容易にするための基準となる位置を設けた電球形ランプ及び照明器具を提供できる。   ADVANTAGE OF THE INVENTION According to this invention, the lightbulb-shaped lamp and lighting fixture which provided the position used as the reference | standard for making automatic assembly easy can be provided.

以下、本発明の実施形態を説明する。図１は本発明の実施形態に係るＬＥＤ電球の正面図である。図１では左半分を断面したものを示している。以下の説明では、発光部としてＬＥＤを用いた場合について説明する。   Embodiments of the present invention will be described below. FIG. 1 is a front view of an LED bulb according to an embodiment of the present invention. FIG. 1 shows a cross section of the left half. In the following description, a case where an LED is used as the light emitting unit will be described.

複数のＬＥＤが面実装されたＬＥＤモジュール１１は、筐体１２の上面部１３に接触して取り付けられている。また、筐体１２の上面部１３には、ＬＥＤモジュール１１を覆ってカバー１４が取り付けられ、ＬＥＤモジュール１１のＬＥＤからの放射光を外部に出射する。一方、筐体１２のカバー１４の反対側には合成樹脂製のケース１５を介して口金１６が取り付けられている。ケース１５の内部は中空となっており、このケース１５の中空部１７にＬＥＤを点灯する点灯回路１８が内蔵されている。   The LED module 11 on which a plurality of LEDs are surface-mounted is attached in contact with the upper surface portion 13 of the housing 12. A cover 14 is attached to the upper surface portion 13 of the housing 12 so as to cover the LED module 11, and radiated light from the LEDs of the LED module 11 is emitted to the outside. On the other hand, a cap 16 is attached to the opposite side of the cover 14 of the housing 12 via a synthetic resin case 15. The inside of the case 15 is hollow, and a lighting circuit 18 for lighting the LED is built in the hollow portion 17 of the case 15.

筐体１２の側面部には複数の放熱フィン１９が筐体１２の中心から外側に向けて放射状に延在するように設けられている。ＬＥＤモジュール１１のＬＥＤから発生する熱は、筐体１２の上面部１３を通って複数の放熱フィン１９に伝熱され、複数の放熱フィン１９から放熱される。   A plurality of heat radiating fins 19 are provided on the side surface of the housing 12 so as to extend radially from the center of the housing 12 to the outside. Heat generated from the LEDs of the LED module 11 is transferred to the plurality of heat radiation fins 19 through the upper surface portion 13 of the housing 12 and is radiated from the plurality of heat radiation fins 19.

また、筐体１２の外面の下部には、筐体１２の基準位置を示す位置決め部としての切欠部２０が設けられている。切欠部２０は筐体１２の下部のケース１５のフランジ部１５ａと接触する部分に設けられているので、目立ち難い部位である。   Further, a notch portion 20 as a positioning portion indicating a reference position of the housing 12 is provided at a lower portion of the outer surface of the housing 12. Since the notch 20 is provided in a portion in contact with the flange portion 15a of the case 15 at the lower part of the housing 12, the notch 20 is a portion that is not easily noticeable.

図２は本発明の実施形態における筐体１２の一例を示す説明図であり、図２（ａ）は正面図、図２（ｂ）は底面図である。図２（ａ）に示すように、切欠部２０は筐体１２の外面の下部における放熱フィン１９の間に設けられている。筐体１２にＬＥＤモジュール１１やケース１５を取り付ける際に、この切欠部２０の位置を基準位置としてＬＥＤモジュール１１やケース１５を筐体１２に取り付けることになる。   2A and 2B are explanatory views showing an example of the housing 12 according to the embodiment of the present invention. FIG. 2A is a front view and FIG. 2B is a bottom view. As shown in FIG. 2A, the notch 20 is provided between the heat radiation fins 19 at the lower part of the outer surface of the housing 12. When the LED module 11 and the case 15 are attached to the housing 12, the LED module 11 and the case 15 are attached to the housing 12 with the position of the notch 20 as a reference position.

図２（ｂ）に示すように、放熱フィン１９は筐体１２に等ピッチ間隔で放射状に形成されている。図２（ｂ）では１６個の放熱フィン１９が２２．５°の等ピッチ間隔で配列された場合を示している。従って、放熱フィン１９の配列は回転対称であるので、放熱フィン１９の配列から筐体１２の基準位置を判断することは困難であるが、切欠部２０の位置を確認することで、筐体１２の基準位置を容易に把握できる。   As shown in FIG. 2B, the heat radiating fins 19 are radially formed on the housing 12 at equal pitch intervals. FIG. 2B shows a case where 16 radiating fins 19 are arranged at an equal pitch interval of 22.5 °. Therefore, since the arrangement of the radiating fins 19 is rotationally symmetric, it is difficult to determine the reference position of the casing 12 from the arrangement of the radiating fins 19, but by checking the position of the notch 20, the casing 12 The reference position can be easily grasped.

例えば、自動組立を行う際に、筐体１２を搭載する保持器具に切欠部２０と掛合する爪部を設けておき、切欠部２０が保持器具の爪部に掛合したときに筐体１２が保持器具に搭載可能となるようにしておく。これにより、筐体１２が保持器具に搭載されたときは、筐体１２は基準位置に対して整列して配置されていることになるので、ＬＥＤモジュール１１やケース１５を筐体１２の所定位置に容易に取り付けることができるようになり、自動組立性を向上させることができる。   For example, when automatic assembly is performed, a claw portion that engages with the notch portion 20 is provided in a holding device on which the housing 12 is mounted, and the housing 12 is held when the notch portion 20 is engaged with the claw portion of the holding device. Make sure that it can be mounted on the instrument. Thus, when the housing 12 is mounted on the holding device, the housing 12 is arranged in alignment with the reference position, so that the LED module 11 and the case 15 are placed at predetermined positions on the housing 12. It can be easily attached to the battery, and the automatic assembly can be improved.

また、外観に影響する外側部分に切欠部２０を設けているが、切欠部２０を設ける場所は筐体１２の下部であるので目立ち難い部位であるので、見栄えに影響を与えることはほとんどなく、放熱性にもほとんど影響がない。さらに、自動化における位置出しが格段に容易になり、設備コスト低減やタクトアップが見込める。また性能上はまったく影響がなく、外観上はまず気がつかない。この部品を製作する上での成型上もまったく問題がない。   In addition, although the cutout 20 is provided in the outer part that affects the appearance, the place where the cutout 20 is provided is a part that is not noticeable because it is the lower part of the housing 12, and therefore it hardly affects the appearance. There is almost no effect on heat dissipation. Furthermore, positioning in automation becomes much easier, and equipment costs can be reduced and tact can be increased. In addition, there is no influence on the performance, and the appearance is not noticeable at first. There is no problem in molding this part.

図３は本発明の実施形態における筐体１２の他の一例を示す説明図であり、図３（ａ）は正面図、図３（ｂ）は底面図である。この一例では、複数の放熱フィン１９の配列間隔の一部を不等間隔で形成し、その不等間隔部分を位置決め部としたものである。図３（ｂ）に示すように、放熱フィン１９は筐体１２に一部が不等間隔で放射状に形成されている。   3A and 3B are explanatory views showing another example of the housing 12 according to the embodiment of the present invention. FIG. 3A is a front view and FIG. 3B is a bottom view. In this example, a part of the arrangement interval of the plurality of radiating fins 19 is formed at unequal intervals, and the unequal interval portions are used as positioning portions. As shown in FIG. 3 (b), the heat radiating fins 19 are partially formed radially on the casing 12 at unequal intervals.

図３（ｂ）では、１６個の放熱フィン１９のうち放熱フィン１９ａ（１９ａ’）と放熱フィン１９ｂ（１９ｂ’）との間が２５°、放熱フィン１９ｂ（１９ｂ’）と放熱フィン１９ｃ（１９ｃ’）との間が２０°の間隔で配列され、残りの放熱フィン１９の間は２２．５°の間隔で配列された場合を示している。従って、放熱フィン１９の配列の位置を確認することで、筐体１２の基準位置を容易に把握できる。   In FIG. 3B, the space between the radiation fins 19a (19a ′) and the radiation fins 19b (19b ′) of the 16 radiation fins 19 is 25 °, and the radiation fins 19b (19b ′) and the radiation fins 19c (19c). ') Is arranged at an interval of 20 °, and the remaining radiating fins 19 are arranged at an interval of 22.5 °. Therefore, the reference position of the housing 12 can be easily grasped by confirming the position of the arrangement of the radiation fins 19.

例えば、自動組立を行う際に、筐体１２を搭載する保持器具に不等間隔で配置された放熱フィン１９と掛合する掛合部を設けておき、不等間隔で配置された放熱フィン１９が保持器具の掛合部に掛合したときに筐体１２が保持器具に搭載可能となるようにしておく。なお、外観に影響する外側部分への形状変更に関しては、一部の放熱フィン１９の不等間隔を大きくし過ぎると人の目を欺けなくなり、外観上問題となるため、放熱フィン１９の放射方向の角度ピッチの１０％前後以下とすることが望ましい。   For example, when automatic assembly is performed, a holding portion that mounts the housing 12 is provided with a hook portion that engages with the radiating fins 19 that are arranged at unequal intervals, and the radiating fins 19 that are arranged at unequal intervals are held. The housing 12 is set so as to be mountable on the holding device when the device is hooked on the hooking portion of the device. Regarding the shape change to the outer part that affects the appearance, if the unequal intervals of some of the heat dissipating fins 19 are excessively increased, it becomes difficult to deceive human eyes, which causes a problem in appearance. It is desirable to be about 10% or less of the angular pitch of the direction.

これにより、筐体１２が保持器具に搭載されたときは、筐体１２は基準位置に対して整列して配置されていることになるので、ＬＥＤモジュール１１やケース１５を筐体１２の所定位置に容易に取り付けることができるようになる。また、人間の目のあいまいさを使用し、一部の放熱フィン１９が不等間隔になっていても容易に気がつかない不等間隔とするだけであるので放熱性にも影響がない。この場合は、図２に示した一例のように切欠部２０を設ける必要がない。   Thus, when the housing 12 is mounted on the holding device, the housing 12 is arranged in alignment with the reference position, so that the LED module 11 and the case 15 are placed at predetermined positions on the housing 12. Can be easily attached to. Further, the ambiguity of human eyes is used, and even if some of the radiating fins 19 are unequally spaced, they are merely unequally spaced so that the heat dissipation is not affected. In this case, it is not necessary to provide the notch 20 as in the example shown in FIG.

次に、本発明の実施形態におけるカバー１４の筐体１２への取り付けについて説明する。図４は本発明の実施形態におけるカバー１４の筐体１２への取り付けの説明図であり、図４（ａ）はカバー１４と筐体１２との斜視図、図４（ｂ）は図４（ａ）のＸ部分の拡大図である。   Next, attachment of the cover 14 to the housing 12 in the embodiment of the present invention will be described. 4A and 4B are explanatory views of attachment of the cover 14 to the housing 12 in the embodiment of the present invention. FIG. 4A is a perspective view of the cover 14 and the housing 12, and FIG. 4B is FIG. It is an enlarged view of X part of a).

図４（ａ）に示すように、カバー１４の筐体１２との接合部には爪部２１が設けられ、筐体１２にはこの爪部２１と掛合する掛合部２２が設けられている。図４では４個の爪部２１がカバー１４に設けられ、４個の掛合部２２が筐体１２に設けられた場合を示している。   As shown in FIG. 4A, a claw portion 21 is provided at a joint portion of the cover 14 with the housing 12, and a hook portion 22 that engages with the claw portion 21 is provided on the housing 12. FIG. 4 shows a case where four claw portions 21 are provided on the cover 14 and four hooking portions 22 are provided on the housing 12.

カバー１４の爪部２１は、図４（ｂ）に示すようにテーパ状に形成されている。すなわち、カバー１４を筐体１２に装着する際のカバー１４の回転方向に対して、爪部２１の前進する面の形状が筐体１２側に設けられた掛合部２２に入り込む入口面よりも小さく、かつ後退する面の形状が筐体１２に設けられた掛合部２２に入り込む入口面よりも大きく形成されている。   The claw portion 21 of the cover 14 is formed in a tapered shape as shown in FIG. That is, with respect to the rotation direction of the cover 14 when the cover 14 is attached to the housing 12, the shape of the surface on which the claw portion 21 advances is smaller than the entrance surface that enters the hooking portion 22 provided on the housing 12 side. In addition, the shape of the retreating surface is formed larger than the entrance surface that enters the engaging portion 22 provided in the housing 12.

これにより、カバー１４と筐体１２とを接合した後に、カバー１４を回転することでテーパ状となった爪部２１と筐体１２内面に設けられた掛合部２２とが噛み合い、軸方向と回転方向の規制が実現できる。また、取り付けの際には大きな力を必要とせず簡単に取り付けを行うことができる。   Thereby, after joining the cover 14 and the housing 12, the claw portion 21 tapered by rotating the cover 14 meshes with the engaging portion 22 provided on the inner surface of the housing 12 to rotate in the axial direction. Directional regulation can be realized. In addition, attachment can be performed easily without requiring a large force.

次に、図５は本発明の実施形態に係る照明装置の説明図である。照明器具本体２３は、天井２４に埋め込み式で取り付けられる。照明器具本体２３には、図１乃至図４に示したＬＥＤ電球２５を装着するためのソケット２６が設けられている。ソケット２６にＬＥＤ電球２５をねじ込むことによりＬＥＤ電球２５は装着され、ＬＥＤ電球２５からの光は反射板２７で反射されて床面に向けて出射される。   Next, FIG. 5 is an explanatory diagram of the illumination device according to the embodiment of the present invention. The lighting fixture body 23 is attached to the ceiling 24 in an embedded manner. The lighting fixture body 23 is provided with a socket 26 for mounting the LED bulb 25 shown in FIGS. The LED bulb 25 is mounted by screwing the LED bulb 25 into the socket 26, and the light from the LED bulb 25 is reflected by the reflecting plate 27 and emitted toward the floor surface.

以上の説明では、発光モジュールであるＬＥＤモジュール１１は、基板に複数個のＬＥＤが実装された場合について説明したが、ＬＥＤ素子単体であっても良い。また、ＬＥＤに代えて有機ＥＬであっても良い。   In the above description, the LED module 11 which is a light emitting module has been described with respect to a case where a plurality of LEDs are mounted on a substrate, but may be a single LED element. Moreover, it may replace with LED and organic EL may be sufficient.

点灯回路は、樹脂製のケース１５内に収容され、筐体の中間空間に配設された場合について説明したが、例えば口金１６内にシリコーン樹脂などにより包囲され収容されていても構わない。   The lighting circuit has been described in the case where it is housed in the resin case 15 and disposed in the middle space of the housing. However, for example, the lighting circuit may be enclosed in the base 16 with silicone resin or the like.

また、本発明の実施形態において、カバーは筐体の一方側に取り付けられているが、発光部が照射する照射方向であり、その光を透過可能であれば、形状や構造、材質などは限定されない。   In the embodiment of the present invention, the cover is attached to one side of the housing. However, the shape, structure, material, and the like are limited as long as the light emitting unit emits light and can transmit the light. Not.

位置決め部は、本発明の実施形態において、筐体１２に形成した切欠部２０、放熱フィン１９の配列間隔の一部を不等間隔で形成した異ピッチとしたが、これらに限定されるものではない。例えば、放熱フィン１９のフィン肉厚を異なるものにしたり、放熱フィン１９の奥行き距離を変えるなどが考えられる。このように、製品組み立て工程の最初から最後まで使用可能とある部位であることが望ましいが、最終製品時には外観から見えない部位であっても構わない。   In the embodiment of the present invention, the positioning part has a different pitch in which a part of the arrangement interval of the notch part 20 and the radiation fin 19 formed in the housing 12 is formed at unequal intervals, but is not limited thereto. Absent. For example, it is conceivable to change the fin thickness of the radiating fin 19 or to change the depth distance of the radiating fin 19. In this way, it is desirable that the part be usable from the beginning to the end of the product assembly process, but it may be a part that cannot be seen from the appearance in the final product.
