Description

本発明は、LED(Light Emitting Diode:発光ダイオード)を用いた照明具、照明具に用いられるカバー、照明具を用いた照明装置に関する。特に、電球形ランプである照明具におけるカバーと本体部との取付け構造に関する。 The present invention relates to a luminaire using an LED (Light Emitting Diode), a cover used for the luminaire, and a luminaire using the luminaire. In particular, the present invention relates to a mounting structure between a cover and a main body of a luminaire, which is a light bulb-shaped lamp.

従来、JIS規格で規定されている一般照明用白熱電球のように、ランプ全体を明るくすることができる電球形ランプ及びこの電球形ランプを用いた照明器具がある。このような電球形ランプでは、光源を覆うカバーが大きくなると共に重くなるため、LEDが取り付けられる本体部からカバーが抜けにくい構造とする必要がある。 Conventionally, there are light bulb-shaped lamps that can brighten the entire lamp and lighting fixtures using the light bulb-shaped lamps, such as incandescent light bulbs for general lighting defined by the JIS standard. In such a bulb-shaped lamp, the cover that covers the light source becomes larger and heavier, so it is necessary to have a structure in which the cover does not easily come off from the main body to which the LED is attached.

特許文献1では、カバーの開口縁部の断面形状を鏃(やじり)状にした照明具が開示されている。 Patent Document 1 discloses an illuminating device in which the cross-sectional shape of the opening edge portion of the cover is shaped like an arrowhead.

特開2010-205645号公報Japanese Unexamined Patent Publication No. 2010-205645

特許文献1の照明具では、カバーの開口縁部の断面形状を鏃状にすることで、カバーが接着剤から抜けにくい構造としている。しかし、カバーと本体部との機械的な係合手段がないため、接着剤の経年劣化によりカバーが抜けてしまうという課題がある。 The luminaire of Patent Document 1 has a structure in which the cover does not easily come off from the adhesive by making the cross-sectional shape of the opening edge of the cover into an arrow shape. However, since there is no mechanical engagement means between the cover and the main body, there is a problem that the cover comes off due to aged deterioration of the adhesive.

本発明は、カバーと本体部とをより確実に接合することができるカバー取付け構造を有する照明具を提供することを目的とする。
目的とする。
An object of the present invention is to provide a luminaire having a cover mounting structure capable of more reliably joining a cover and a main body portion.
The purpose.

本発明に係る照明具は、光源が配置される光源配置部と、前記光源配置部の周囲に環状に形成された係合溝部とを有する本体部と、前記光源配置部を覆うように前記本体部に取り付けられたカバーであり、前記係合溝部に挿入される筒状の取付部を有するカバーとを備え、前記取付部は、筒状の周面から前記周面と交差する方向に突き出すように形成された第1係合突起部と筒状の前記周面から前記周面と交差する前記第1係合突起部の方向とは異なる方向に突き出すように形成された第2係合突起部とを有し、前記第1係合突起部は、前記係合溝部の側壁と対向した状態で前記側壁によって筒軸方向の移動が規制されており、前記第2係合突起部は前記係合溝部に形成された回動規制部に係止された状態で回転方向の移動が規制されている。 The illuminator according to the present invention has a light source arrangement portion in which a light source is arranged, a main body portion having an engagement groove portion formed in an annular shape around the light source arrangement portion, and the main body so as to cover the light source arrangement portion. A cover attached to the portion, including a cover having a tubular mounting portion to be inserted into the engaging groove portion, and the mounting portion so as to protrude from the tubular peripheral surface in a direction intersecting the peripheral surface. A second engaging protrusion formed so as to protrude from the tubular peripheral surface of the first engaging protrusion formed in a direction different from the direction of the first engaging protrusion intersecting the peripheral surface. The first engaging protrusion is restricted from moving in the tubular axis direction by the side wall in a state of facing the side wall of the engaging groove, and the second engaging protrusion is engaged. The movement in the rotation direction is restricted in a state of being locked to the rotation restricting portion formed in the groove portion.

本発明に係る照明具によれば、取付部が、筒状の周面から突き出すように形成された第1係合突起部と第2係合突起部とを有し、第1係合突起部が、係合溝部の側壁と対向した状態で側壁によって筒軸方向の移動が規制されており、前記第2係合突起部は前記係合溝部に形成された回動規制部に係止された状態で回転方向の移動が規制されているので、カバーは本体部から外れることがなく確実に接合することができるという効果を奏する。 According to the illuminator according to the present invention, the mounting portion has a first engaging protrusion portion and a second engaging protrusion portion formed so as to protrude from a tubular peripheral surface, and the first engaging protrusion portion is provided. However, the movement in the tubular axis direction is restricted by the side wall in a state of facing the side wall of the engaging groove portion, and the second engaging protrusion portion is locked to the rotation restricting portion formed in the engaging groove portion. Since the movement in the rotation direction is restricted in the state, the cover has the effect that it can be securely joined without coming off from the main body.

図7の(b)に示すように、筒部37の内部は空洞部378となっている。空洞部378には、内部に電源部5が収納された絶縁部2が配置される。
図9の(a)に示すように、空洞部378を形成する上面である内面部36には、絶縁部2の第1凸部250が嵌まり込む第1凹部360が形成される。第1凸部250が第1凹部360に嵌った状態で、ネジ貫通孔32と絶縁部2のネジ孔251とが連通する。
また、図9の(b)に示すように、内面部36には、絶縁部2の第2凸部252が嵌まり込む第2凹部361が形成される。第2凸部252が第2凹部361に嵌ることにより、絶縁部2の回転方向の位置決めをする。
第2凹部361の幅W15(図8の(b))は、第2凸部252の幅W29(図6の(a))より若干広く形成される。
As shown in FIG. 7B, the inside of the tubular portion 37 is a hollow portion 378. In the hollow portion 378, an insulating portion 2 in which the power supply portion 5 is housed is arranged.
As shown in FIG. 9A, a first concave portion 360 into which the first convex portion 250 of the insulating portion 2 is fitted is formed on the inner surface portion 36 which is the upper surface forming the hollow portion 378. With the first convex portion 250 fitted in the first concave portion 360, the screw through hole 32 and the screw hole 251 of the insulating portion 2 communicate with each other.
Further, as shown in FIG. 9B, the inner surface portion 36 is formed with a second concave portion 361 into which the second convex portion 252 of the insulating portion 2 is fitted. By fitting the second convex portion 252 into the second concave portion 361, the insulating portion 2 is positioned in the rotational direction.
The width W15 of the second concave portion 361 ((b) in FIG. 8) is formed to be slightly wider than the width W29 of the second convex portion 252 ((a) in FIG. 6).

図9の(b)に示すように、係合溝部34は、両側の側壁349と側壁349の底に設けられた底部344とを有する。また、係合溝部34は、底部344に対向する位置に開口部345を有する。係合溝部34の深さはL13である。
両側の側壁349のうち内側の側壁349を側壁内周部340とし、外側の側壁349を側壁外周部341とする。側壁外周部341は係合溝部34の側壁349の一例である。側壁外周部341の上部には、側壁外周部341の上端から外側に開く傾斜を有する第2外周部342が形成される。
As shown in FIG. 9B, the engaging groove portion 34 has side walls 349 on both sides and a bottom portion 344 provided at the bottom of the side wall 349. Further, the engaging groove portion 34 has an opening 345 at a position facing the bottom portion 344. The depth of the engaging groove portion 34 is L13.
Of the side walls 349 on both sides, the inner side wall 349 is referred to as a side wall inner peripheral portion 340, and the outer side wall 349 is referred to as a side wall outer peripheral portion 341. The side wall outer peripheral portion 341 is an example of the side wall 349 of the engaging groove portion 34. A second outer peripheral portion 342 having an inclination that opens outward from the upper end of the side wall outer peripheral portion 341 is formed on the upper portion of the side wall outer peripheral portion 341.

図9の(b)に示すように、側壁外周部341は、底部344から上方に向かって徐々に内側に傾斜するように形成されている。よって、底部344の幅W27より、開口部345の幅W26の方が幅W25だけ狭く形成されている。
つまり、係合溝部34は下端部の幅より上端部(開口端部)の幅が若干狭くなっており、係合溝部34の側壁外周部341は、上端部(開口端部)から下端部に向って徐々に外側に広がるように若干傾斜している。
As shown in FIG. 9B, the side wall outer peripheral portion 341 is formed so as to gradually incline inward from the bottom portion 344. Therefore, the width W26 of the opening 345 is formed narrower by the width W25 than the width W27 of the bottom portion 344.
That is, the width of the upper end portion (open end portion) of the engagement groove portion 34 is slightly narrower than the width of the lower end portion, and the side wall outer peripheral portion 341 of the engagement groove portion 34 is from the upper end portion (open end portion) to the lower end portion. It is slightly inclined so that it gradually spreads outward.

このように、底部344の幅W27を開口部345の幅W26よりも広くすることにより、後述するカバー4の第1係合突起部46が係合溝部34から抜けにくくなり、係合溝部34と第1係合突起部46とがより確実に係合するようにしている。
係合溝部34は二次加工によって全周に形成される。なお、係合溝部34は第1係合突起部46の幅W9(図12の(b))以上の寸法であれば部分的に形成されても良い。

図11に示すように、第2係合突起部47は、筒部内周面部4502から半円筒状に立ち上がる。第2係合突起部47は、筒部内周面部4502から半円筒状に立ち上がる周壁面である突起内周面部470、突起内周面部470の上面であり、筒部内周面部4502から立ち上がる突起上面部471、及び、突起内周面部470の下面であり、筒部内周面部4502から立ち上がる突起下面部472を有する。突起下面部472は、459と連続した平面である。
第2係合突起部47の高さ寸法は、係合溝部34の深さ寸法L13よりも小さい。すなわち、第2係合突起部47の突起上面部472の高さは、光源配置部30の高さよりも低い。
The second engaging protrusion 47 projects from the inner peripheral surface portion 4502 of the cylinder portion toward the inside of the cylinder portion 450.
As shown in FIG. 11, the second engaging protrusion 47 rises from the inner peripheral surface portion 4502 of the tubular portion in a semi-cylindrical shape. The second engaging protrusion 47 is the upper surface of the protrusion inner peripheral surface portion 470 and the protrusion inner peripheral surface portion 470, which are the peripheral wall surfaces rising from the tubular portion inner peripheral surface portion 4502 in a semi-cylindrical shape, and the protrusion upper surface portion rising from the tubular portion inner peripheral surface portion 4502. It has a protrusion lower surface portion 472 that is the lower surface of the protrusion inner peripheral surface portion 470 and rises from the tubular portion inner peripheral surface portion 4502. The protrusion lower surface portion 472 is a plane continuous with 459.
The height dimension of the second engaging protrusion 47 is smaller than the depth dimension L13 of the engaging groove portion 34. That is, the height of the protrusion upper surface portion 472 of the second engaging protrusion portion 47 is lower than the height of the light source arrangement portion 30.

取付部45は、周面に第2係合突起部47を少なくとも2つ有する。図12の(b)に示すように、取付部45の筒状の直径上において対向する2箇所に設けられる。よって、筒部内周面部4502の最小内径W10は、第2係合突起部47を含めた取付部45の最小内径より若干小さくなる。
第2係合突起部47を収容する本体部3の第2挿入切欠き部380は、取付部45が係合溝部34に挿入される際に側壁349の側壁内周部340において第2係合突起部47に対応する位置に形成される。
The mounting portion 45 has at least two second engaging protrusions 47 on the peripheral surface. As shown in FIG. 12 (b), the mounting portion 45 is provided at two facing positions on the tubular diameter. Therefore, the minimum inner diameter W10 of the inner peripheral surface portion 4502 of the cylinder portion is slightly smaller than the minimum inner diameter of the mounting portion 45 including the second engaging protrusion portion 47.
The second insertion notch portion 380 of the main body portion 3 accommodating the second engagement protrusion portion 47 is secondly engaged in the side wall inner peripheral portion 340 of the side wall 349 when the mounting portion 45 is inserted into the engagement groove portion 34. It is formed at a position corresponding to the protrusion 47.

図11に示すように、カバー4は、第1係合突起部46の上部のカバー主部40の表面に、第1係合突起部46の位置を示すガイドマーク43を有する。ガイドマーク43は、第1係合突起部46の位置を作業者に認識させるためのマークである。照明具100の光学性能及び意匠性等を考慮すると、ガイドマーク43はカバー主部40の下端部寄り、すなわち第2主部42に設けられることが好ましい。
ガイドマーク43は、成形による立体形状である。なお、ガイドマーク43は、印刷、刻印などでも良い。
As shown in FIG. 11, the cover 4 has a guide mark 43 indicating the position of the first engaging protrusion 46 on the surface of the cover main portion 40 above the first engaging protrusion 46. The guide mark 43 is a mark for making the operator recognize the position of the first engaging protrusion 46. Considering the optical performance and design of the illuminating tool 100, it is preferable that the guide mark 43 is provided near the lower end portion of the cover main portion 40, that is, on the second main portion 42.
The guide mark 43 has a three-dimensional shape formed by molding. The guide mark 43 may be printed, engraved, or the like.

図14から図16を用いて、本体部3とカバー4との取付け手順について説明する。
(1)作業者は、ガイドマーク43により第1係合突起部46の位置を確認し、第1係合突起部46を本体部3の係合溝部34の第1挿入切欠き部35の位置に合わせながら、取付部45を係合溝部34に挿入する。図14の(a)(b)及び図16の(a)は(1)の手順を示している。
このとき、図14の(b)に示すように、第1係合突起部46の突起外周面部465は、係合溝部34の側壁外周部341よりも外側に位置している。すなわち、第1係合突起部46の厚みは、対応する側壁外周部341と側壁内周部340との間隔よりも大きい。
つまり、取付部45の下端部における、カバー中心軸から第1係合突起部46の外周までの最短距離は、本体中心軸から第1挿入切欠き部35の外壁である切欠き外周部350までの最短距離より若干小さい。また、取付部45の下端部における、カバー中心軸から第1係合突起部46の外周までの最短距離は、本体中心軸から係合溝部34の側壁外周部341までの最短距離より若干大きい。
図16の(a)に示すように、作業者が(1)の手順で取付部45を係合溝部34に挿入した状態で、第2係合突起部47は第2挿入切欠き部380に挿入されている。
A procedure for attaching the main body 3 and the cover 4 will be described with reference to FIGS. 14 to 16.
(1) The operator confirms the position of the first engaging protrusion 46 by the guide mark 43, and the first engaging protrusion 46 is the position of the first insertion notch 35 of the engaging groove 34 of the main body 3. The mounting portion 45 is inserted into the engaging groove portion 34 while adjusting to the above. 14 (a) and 14 (a) and 16 (a) show the procedure of (1).
At this time, as shown in FIG. 14B, the protrusion outer peripheral surface portion 465 of the first engaging protrusion 46 is located outside the side wall outer peripheral portion 341 of the engaging groove portion 34. That is, the thickness of the first engaging protrusion 46 is larger than the distance between the corresponding side wall outer peripheral portion 341 and the side wall inner peripheral portion 340.
That is, the shortest distance from the cover central axis to the outer periphery of the first engaging protrusion 46 at the lower end of the mounting portion 45 is from the main body central axis to the notch outer peripheral portion 350 which is the outer wall of the first insertion notch portion 35. Slightly smaller than the shortest distance. Further, the shortest distance from the center axis of the cover to the outer periphery of the first engaging protrusion 46 at the lower end of the mounting portion 45 is slightly larger than the shortest distance from the central axis of the main body to the outer peripheral portion 341 of the side wall of the engaging groove portion 34.
As shown in FIG. 16A, the second engaging protrusion 47 is inserted into the second insertion notch 380 while the worker inserts the mounting portion 45 into the engaging groove 34 in the procedure of (1). It has been inserted.

(2)次に、作業者は、カバー4をT1方向に回転させる。あるいは、作業者は、本体部3をT2方向に回転させる。作業者は、カバー4をT1方向に回転させると共に、本体部3をT2方向に回転させてもよい。
図16の(b)(c)は(2)の手順を示しており、図15は及び図16の(d)は(2)の手順後を示している。
図16に示すように、この回転により、第1係合突起部46は、本体部3の係合溝部34における第1挿入切欠き部35の位置から、側壁外周部341と側壁内周部340とに挟まれた位置に移動する。そして、この回転により、第2係合突起部47は、本体部3の係合溝部34における第2挿入切欠き部380の位置からスライド部381を通過して回動規制凹部382の位置に移動する。
(2) Next, the operator rotates the cover 4 in the T1 direction. Alternatively, the operator rotates the main body 3 in the T2 direction. The operator may rotate the cover 4 in the T1 direction and the main body 3 in the T2 direction.
16 (b) and 16 (c) show the procedure of (2), FIG. 15 and FIG. 16 (d) show after the procedure of (2).
As shown in FIG. 16, due to this rotation, the first engaging protrusion 46 has the side wall outer peripheral portion 341 and the side wall inner peripheral portion 340 from the position of the first insertion notch portion 35 in the engaging groove portion 34 of the main body portion 3. Move to the position between and. Then, due to this rotation, the second engaging protrusion 47 moves from the position of the second insertion notch 380 in the engaging groove 34 of the main body 3 to the position of the rotation restricting recess 382 through the slide portion 381. do.

上述したように、第1係合突起部46の厚みは側壁外周部341と側壁内周部340との間隔よりも大きいので、第1係合突起部46が側壁外周部341と側壁内周部340との間に圧入される。第1係合突起部46が側壁外周部341と側壁内周部340との間に圧入されると、第1係合突起部46は、係合溝部34の側壁である側壁外周部341と対向した状態で側壁の反力によって弾性変形する。 As described above, since the thickness of the first engaging protrusion 46 is larger than the distance between the side wall outer peripheral portion 341 and the side wall inner peripheral portion 340, the first engaging protrusion 46 is the side wall outer peripheral portion 341 and the side wall inner peripheral portion. It is press-fitted between the 340 and the 340. When the first engaging protrusion 46 is press-fitted between the side wall outer peripheral portion 341 and the side wall inner peripheral portion 340, the first engaging protrusion 46 faces the side wall outer peripheral portion 341 which is the side wall of the engaging groove portion 34. In this state, it is elastically deformed by the reaction force of the side wall.

図15に示すように、突起外周面部465は、係合溝部34の側壁外周部341によりP方向に押圧される。すなわち、第1係合突起部46が若干弾性変形した状態で、突起外周面部465または突起先端部466が係合溝部34の側壁外周部341に押し付けられる。突起外周面部465または突起先端部466は、矢印Pの向きに押し返される。このようにして第1係合突起部46は係合溝部34によって係止され、カバー4は本体部3と強く密着する。 As shown in FIG. 15, the protrusion outer peripheral surface portion 465 is pressed in the P direction by the side wall outer peripheral portion 341 of the engaging groove portion 34. That is, in a state where the first engaging protrusion 46 is slightly elastically deformed, the protrusion outer peripheral surface portion 465 or the protrusion tip portion 466 is pressed against the side wall outer peripheral portion 341 of the engaging groove portion 34. The protrusion outer peripheral surface portion 465 or the protrusion tip portion 466 is pushed back in the direction of the arrow P. In this way, the first engaging protrusion 46 is locked by the engaging groove 34, and the cover 4 is in strong contact with the main body 3.

また、第2係合突起部47の厚みは側壁外周部341と側壁内周部340との間隔よりも大きいので、第2係合突起部47が側壁外周部341と側壁内周部340との間に圧入される。詳しくは、図16の(b)(c)に示すように、第2係合突起部47は、スライド部381を移動しながら、第2係合突起部47の厚みより間隔が狭い部分を通過する。このとき、第2係合突起部46の突起内周面部470が、係合溝部34の側壁である側壁内周部340を若干後退させたスライド部381の反力を受けるため、第2係合突起部47は弾性変形する。そして、取付部45の第2係合突起部47が形成されている部分は、取付部45の直径方向の外側に向かって弾性変形する。 Further, since the thickness of the second engaging protrusion 47 is larger than the distance between the side wall outer peripheral portion 341 and the side wall inner peripheral portion 340, the second engaging protrusion 47 is the side wall outer peripheral portion 341 and the side wall inner peripheral portion 340. It is press-fitted in between. Specifically, as shown in FIGS. 16B and 16C, the second engaging protrusion 47 passes through a portion narrower than the thickness of the second engaging protrusion 47 while moving the slide portion 381. do. At this time, the protrusion inner peripheral surface portion 470 of the second engaging protrusion 46 receives the reaction force of the slide portion 381 that slightly retracts the side wall inner peripheral portion 340, which is the side wall of the engaging groove portion 34, and thus receives the second engagement. The protrusion 47 is elastically deformed. Then, the portion of the mounting portion 45 on which the second engaging projection portion 47 is formed is elastically deformed toward the outside in the radial direction of the mounting portion 45.

図16の(d)に示すように、第2係合突起部47は、回動規制凹部382の位置に移動すると弾性変形が解消され、回動規制凹部382と係合する。このため、第2係合突起部47は、回動規制凹部382によって係止され、係合溝部34内を回転方向に移動することが規制される。このようにして、カバー4は本体部3に対する回転が規制される、 As shown in FIG. 16D, when the second engaging protrusion 47 moves to the position of the rotation restricting recess 382, the elastic deformation is eliminated and the second engaging projection portion 382 engages with the rotation restricting recess 382. Therefore, the second engaging protrusion 47 is locked by the rotation restricting recess 382, and is restricted from moving in the engaging groove 34 in the rotational direction. In this way, the cover 4 is restricted from rotating with respect to the main body 3.

以上のように、カバー4の取付部45が、第1挿入切欠き部35に第1係合突起部46を収容しながら係合溝部34に挿入された状態から係合溝部34の周方向(溝方向ともいう)に回転すると、第1係合突起部46は、取付部45の回転にしたがって第1挿入切欠き部35の位置から側壁である側壁外周部341と対向した位置に移動する。
そして、カバー4の取付部45が、第2挿入切欠き部380に第2係合突起部47を収容された状態から係合溝部34の周方向(溝方向ともいう)に回転すると、第2係合突起部47は、取付部45の回転にしたがって第2挿入切欠き部380の位置から側壁である側壁内周部340を後退させたスライド部381を通過して、第1挿入切欠き部35と対向した回動規制凹部382の位置に移動する。
第1係合突起部46は、側壁外周部341と対向する位置において、側壁外周部341により弾性変形するため、少なくとも側壁外周部341は第1係合突起部46よりも硬い材料であることが好適である。また、第2係合突起部47は、スライド部381を通過する位置において、スライド部381により弾性変形するため、少なくともスライド部381は第2係合突起部47よりも硬い材料であることが好適である。
As described above, from the state in which the mounting portion 45 of the cover 4 is inserted into the engaging groove portion 34 while accommodating the first engaging protrusion portion 46 in the first insertion notch portion 35, the circumferential direction of the engaging groove portion 34 ( When rotated in the groove direction), the first engaging protrusion 46 moves from the position of the first insertion notch 35 to the position facing the outer peripheral portion 341 of the side wall, which is the side wall, according to the rotation of the mounting portion 45.
Then, when the mounting portion 45 of the cover 4 rotates in the circumferential direction (also referred to as the groove direction) of the engaging groove portion 34 from the state where the second engaging protrusion portion 47 is accommodated in the second insertion notch portion 380, the second The engaging protrusion 47 passes through the slide portion 381 in which the side wall inner peripheral portion 340, which is the side wall, is retracted from the position of the second insertion notch portion 380 according to the rotation of the mounting portion 45, and the first insertion notch portion 47. It moves to the position of the rotation restricting recess 382 facing the 35.
Since the first engaging protrusion 46 is elastically deformed by the side wall outer peripheral portion 341 at a position facing the side wall outer peripheral portion 341, at least the side wall outer peripheral portion 341 is made of a material harder than the first engaging protrusion portion 46. Suitable. Further, since the second engaging protrusion 47 is elastically deformed by the slide portion 381 at the position where it passes through the slide portion 381, it is preferable that at least the slide portion 381 is made of a material harder than the second engaging protrusion 47. Is.

<<本実施の形態の効果の説明>>
以上のように、本実施の形態に係る照明具100では、取付部45の第1係合突起部46が本体部3の中心軸方向に沿って第1挿入切欠き部35に挿入され、カバー4を本体部3へ押付けた状態で、カバー4または本体部3のいずれかを中心軸を基準にして回転する。そして、第1係合突起部46が第1挿入切欠き部35から係合溝部34に移動した位置で回転を停止する。このようにカバー4が本体部3に取り付けられた状態では、取付部45の第1係合突起部46が若干弾性変形した状態となっており、第1係合突起部46の弾性力によって第1係合突起部46の突起先端部466が係合溝部34の若干傾斜した側壁外周部341に押し付けられる。このとき、カバー4は、若干傾斜した側壁外周部341の反力を受けるので、第1係合突起部46が本体部3の係合溝部34の下端部に向って押し戻される。つまり、カバー4は本体部3に密着して取り付けられることになり、本体部3に取り付けられたカバー4は、本体部3から外れるおそれがない。
このように、取付部45に形成された第1係合突起部46と係合溝部34に形成された係合溝部とは、第1の方向である本体3の中心軸方向にカバー4が移動することを規制する第1の移動規制機構を構成する。
<< Explanation of the effect of this embodiment >>
As described above, in the luminaire 100 according to the present embodiment, the first engaging projection portion 46 of the mounting portion 45 is inserted into the first insertion notch portion 35 along the central axis direction of the main body portion 3, and the cover is covered. With the 4 pressed against the main body portion 3, either the cover 4 or the main body portion 3 is rotated with reference to the central axis. Then, the rotation is stopped at the position where the first engaging protrusion 46 moves from the first insertion notch 35 to the engaging groove 34. In the state where the cover 4 is attached to the main body 3 in this way, the first engaging protrusion 46 of the mounting portion 45 is in a slightly elastically deformed state, and the elastic force of the first engaging protrusion 46 causes the cover 4 to be slightly elastically deformed. 1 The protrusion tip portion 466 of the engagement protrusion portion 46 is pressed against the slightly inclined side wall outer peripheral portion 341 of the engagement groove portion 34. At this time, since the cover 4 receives the reaction force of the slightly inclined side wall outer peripheral portion 341, the first engaging projection portion 46 is pushed back toward the lower end portion of the engaging groove portion 34 of the main body portion 3. That is, the cover 4 is attached in close contact with the main body 3, and the cover 4 attached to the main body 3 is not likely to come off from the main body 3.
As described above, the cover 4 moves in the central axis direction of the main body 3 which is the first direction between the first engaging protrusion 46 formed in the mounting portion 45 and the engaging groove portion formed in the engaging groove portion 34. It constitutes a first movement control mechanism that regulates what is done.

そして、本実施の形態に係る照明具100では、取付部45の第2係合突起部47が本体部3の中心軸方向に沿って第2挿入切欠き部380に挿入され、カバー4を本体部3へ押付けた状態で、カバー4または本体部3のいずれかを中心軸を基準にして回転する。そして、第2係合突起部47が第2挿入切欠き部380から係合溝部34内のスライド部381を通過して回動規制凹部382に移動した位置で回転を停止する。このようにカバー4が本体部3に取り付けられた状態では、取付部45の第2係合突起部47が回動規制凹部382によって回転方向の移動を規制された状態となっており、第2係合突起部47が形成された取付部45は、係合溝部34内を回転しない。このため、第1係合突起部46は係合溝部34に係止された状態を維持し、再び第1挿入切欠き部35の位置に移動することはない。つまり、カバー4は本体部3に密着して取り付けられる状態を維持することになり、本体部3に取り付けられたカバー4は、本体部3から外れるおそれがない。
このように、取付部45に形成された第2係合突起部47と係合溝部34に形成された回動規制凹部382とは、第2の方向であり環状に形成された係合溝部34の溝方向である回転方向にカバー4が移動することを規制する第2の移動規制機構を構成する。
Then, in the luminaire 100 according to the present embodiment, the second engaging protrusion 47 of the mounting portion 45 is inserted into the second insertion notch portion 380 along the central axis direction of the main body portion 3, and the cover 4 is inserted into the main body. While pressed against the portion 3, the cover 4 or the main body portion 3 is rotated with respect to the central axis. Then, the rotation is stopped at the position where the second engaging protrusion 47 passes through the slide portion 381 in the engaging groove portion 34 from the second insertion notch portion 380 and moves to the rotation restricting recess 382. In the state where the cover 4 is attached to the main body 3 in this way, the second engaging protrusion 47 of the attachment portion 45 is in a state where the movement in the rotation direction is restricted by the rotation restricting recess 382, and the second The mounting portion 45 on which the engaging protrusion portion 47 is formed does not rotate in the engaging groove portion 34. Therefore, the first engaging protrusion 46 maintains the state of being locked to the engaging groove 34, and does not move to the position of the first insertion notch 35 again. That is, the cover 4 is maintained in a state of being closely attached to the main body portion 3, and the cover 4 attached to the main body portion 3 is not likely to come off from the main body portion 3.
As described above, the second engaging protrusion 47 formed in the mounting portion 45 and the rotation restricting recess 382 formed in the engaging groove portion 34 are in the second direction, and the engaging groove portion 34 formed in an annular shape. It constitutes a second movement regulation mechanism that regulates the movement of the cover 4 in the rotation direction which is the groove direction of the cover 4.

また、本実施の形態に係る照明具100では、照明具(電球形照明ランプ)全体における本体部(ヒートシンク)の占める割合が小さいので、照明具の軽量化も図られる。一方、カバーは相対的に大きくなるため重くなり、相対的に小さくなる本体部に対して確実に取り付ける必要がある。そこで、本実施の形態に係る照明具100のカバーと本体部との取付け構造によれば、より確実に取り付けられ、本体部に取り付けられたカバーが相対的に重くなっても本体部から外れるおそれがない。 Further, in the luminaire 100 according to the present embodiment, since the proportion of the main body portion (heat sink) in the entire luminaire (bulb-shaped illuminating lamp) is small, the weight of the luminaire can be reduced. On the other hand, since the cover is relatively large, it becomes heavy, and it is necessary to securely attach it to the relatively small main body. Therefore, according to the attachment structure between the cover of the luminaire 100 and the main body according to the present embodiment, the cover 100 can be attached more reliably, and even if the cover attached to the main body becomes relatively heavy, it may come off from the main body. There is no.

また、本実施の形態に係る照明具100では、照明具(電球形照明ランプ)全体におけるカバーの占める割合が大きい。このため、使用者が照明具を照明器具に取り付けたり、照明具を照明器具から取り外したりする際には、カバーを掴んで作業を行うことが想定される。照明具は照明器具に確実に取り付けられる必要があり、確実に取り外される必要がある。そこで、本実施の形態に係る照明具100のカバーと本体部との取付け構造によれば、カバーを掴んで作業が行われても、カバーは本体部に対して回転するおそれがないし、本体部から外れるおそれがない。 Further, in the luminaire 100 according to the present embodiment, the proportion of the cover in the entire luminaire (bulb-shaped illuminating lamp) is large. Therefore, when the user attaches the luminaire to the luminaire or removes the luminaire from the luminaire, it is assumed that the user grabs the cover to perform the work. The luminaire needs to be securely attached to the luminaire and must be securely removed. Therefore, according to the mounting structure between the cover of the luminaire 100 and the main body according to the present embodiment, there is no possibility that the cover will rotate with respect to the main body even if the work is performed by grasping the cover, and the main body There is no risk of coming off.

上側カバーと下側カバーとの2つの部品で構成される場合、カバーの最大径部分において上下に分割されているので超音波溶着や振動溶着などより固着する必要があった。また、異なる形の別々のカバーを使用する必要があるため、部品の材料費を増大させてしまうおそれがある。異なる形のカバーを成形するために別々の金型を使用する必要があり、金型費を増大させてしまうおそれがある。組立工程にカバーを固着させる工程を設ける必要があり、組立工程を複雑にしたり、固着の品質を維持管理したりする手間が発生し、製造コスト、製造品質の面で課題が残る。
一方、本実施の形態に係る照明具100では、カバー主部と取付部とが1つの部品で形成されているため、製造コストを削減できると共に、製造品質も向上させることができる。
また、外観意匠部品であり光を透過する光学部品であるカバーは、照明装置(ランプ)にとって最も重要な部品であり、カバーの表面に固着痕を残す方法は、意匠性、光学特性を損なうおそれがある。一方、本実施の形態に係る照明具100では、カバー主部と取付部とが1つの部品で形成されているため、意匠性、光学特性を損なうおそれがない。
以上のように、本実施の形態に係る照明具100によれば、簡単な構成によりカバーと本体部とを確実に接合することができるので、製造コストを削減できる。また、カバーは1つの部品により形成されているので、製造品質も向上させると共に、意匠性、光学特性を損なうおそれがない。
When composed of two parts, an upper cover and a lower cover, the maximum diameter portion of the cover is divided into upper and lower parts, so that it is necessary to fix the cover by ultrasonic welding or vibration welding. Also, the need to use different covers of different shapes can increase the material cost of the parts. Separate molds need to be used to mold differently shaped covers, which can increase mold costs. It is necessary to provide a process for fixing the cover in the assembly process, which complicates the assembly process and requires time and effort to maintain and manage the quality of the fixing, which leaves problems in terms of manufacturing cost and manufacturing quality.
On the other hand, in the luminaire 100 according to the present embodiment, since the cover main portion and the mounting portion are formed of one component, the manufacturing cost can be reduced and the manufacturing quality can be improved.
In addition, the cover, which is an exterior design component and an optical component that transmits light, is the most important component for a lighting device (lamp), and a method of leaving a sticking mark on the surface of the cover may impair the design and optical characteristics. There is. On the other hand, in the luminaire 100 according to the present embodiment, since the cover main portion and the mounting portion are formed of one component, there is no possibility of impairing the design and optical characteristics.
As described above, according to the luminaire 100 according to the present embodiment, the cover and the main body can be reliably joined by a simple configuration, so that the manufacturing cost can be reduced. Further, since the cover is formed of one component, the manufacturing quality is improved and there is no possibility of impairing the design and optical characteristics.

カバー取付部と本体部とが取り付けられる部分は、カバーの最大径より小さい径となり、光源素子(LED)は本体部(ヒートシンク)のカバーに覆われる部分に形成された光源配置部に配置(実装)される。そこで、全配光形(広配光形)の配光特性を得るためには、光源素子(LED)は光源配置部のなるべく外縁側に配置(実装)されることが好ましい。このため、取付部は、光源配置部の更に外縁部の極々限られた領域に取り付ける必要がある。
本実施の形態に係るカバーと取付部との取付け構造によれば、取付部の周面から突出した第1係合突起部を係合溝部の側壁外周部により弾性変形させて密着させるので、係合溝部の幅を小さくして、光源配置部の面積を大きくすることができる。
なお、例えば、本体部に対するカバーの寸法は、摂氏25度以上の環境で調整し、照明具を点灯させたときにカバーが若干膨張するようにすれば、少なくとも照明具に通電させているときには、カバーが落下しない。
The part where the cover mounting part and the main body part are attached has a diameter smaller than the maximum diameter of the cover, and the light source element (LED) is arranged (mounted) in the light source arrangement part formed in the part covered by the cover of the main body part (heat sink). ). Therefore, in order to obtain the light distribution characteristics of the full light distribution type (wide light distribution type), it is preferable that the light source element (LED) is arranged (mounted) on the outer edge side of the light source arrangement portion as much as possible. Therefore, the mounting portion needs to be mounted in a very limited area of the outer edge portion of the light source arrangement portion.
According to the mounting structure of the cover and the mounting portion according to the present embodiment, the first engaging protrusion protruding from the peripheral surface of the mounting portion is elastically deformed by the outer peripheral portion of the side wall of the engaging groove portion to be brought into close contact with the cover. The width of the groove portion can be reduced to increase the area of the light source arrangement portion.
For example, if the dimensions of the cover with respect to the main body are adjusted in an environment of 25 degrees Celsius or higher so that the cover expands slightly when the luminaire is turned on, at least when the luminaire is energized. The cover does not fall.

<<他の構成>>
本実施の形態では、第1係合突起部は、取付部の外側の周面である筒部外周面部から突出するように形成されていた。しかし、第1係合突起部が取付部の内側の周面から内側に突出するように取り付けられていてもよい。あるいは、取付部の両側の周面から突出していてもよい。
例えば、第1係合突起部が取付部の内側の周面から突出する場合、第1係合突起部を側壁内周部に形成された凹みであるネジ貫通孔に沿わせながら、取付部を係合溝部に挿入する。その後、カバーを回転させて、第1係合突起部が側壁内周部に対向する位置まで移動させる。このとき、本実施の形態と同様に、側壁内周部により第1係合突起部が弾性変形され、カバーと本体部とが密着する。
また、例えば、第1係合突起部が取付部の両側の周面から突出する場合、第1係合突起部を側壁外周部に形成された第1挿入切欠き部と側壁内周部に形成されたネジ貫通孔とに沿わせながら、取付部を係合溝部に挿入する。その後、カバーを回転させて、第1係合突起部が側壁外周部と側壁内周部とに挟まれる位置まで移動させる。このとき、本実施の形態と同様に、側壁外周部と側壁内周部とに挟まれ第1係合突起部が弾性変形され、カバーと本体部とが密着する。
<< Other configurations >>

However, the first engaging protrusion may be mounted so as to project inward from the inner peripheral surface of the mounting portion. Alternatively, it may protrude from the peripheral surfaces on both sides of the mounting portion.
For example, when the first engaging protrusion protrudes from the inner peripheral surface of the mounting portion, the mounting portion is placed along the screw through hole which is a recess formed in the inner peripheral portion of the side wall. Insert it into the engagement groove. After that, the cover is rotated to move the first engaging protrusion to a position facing the inner peripheral portion of the side wall.

Insert the mounting portion into the engaging groove portion along the threaded through hole. After that, the cover is rotated to move the first engaging protrusion to a position where it is sandwiched between the outer peripheral portion of the side wall and the inner peripheral portion of the side wall. At this time, as in the present embodiment, the first engaging protrusion is elastically deformed by being sandwiched between the outer peripheral portion of the side wall and the inner peripheral portion of the side wall, and the cover and the main body portion are in close contact with each other.

また、本実施の形態では光源素子67としてLEDを用いているが、LED以外の光源素子でもよい。具体的には、光源素子として、有機EL(Organic electro-luminescence:OEL)あるいはレーザ(Light Amplification by Stimulated Emission of Radiation:LASER)を用いてもよい。
本実施の形態では、カバーと本体部との取付け構造について、LEDを光源として用いた白熱電球と完全同一または同等のフォルムの電球形ランプを例として説明したが、その他の形態の電球形ランプでも適用可能である。例えば、LEDを光源として用いたミニクリプトンタイプの小形電球でも適用可能である。
なお、このように形成された本体部3は、JIS C 8158に規定されているA形の電球形ランプ、T形、G形として規定されている電球形ランプにも適用できる。
Further, although the LED is used as the light source element 67 in this embodiment, a light source element other than the LED may be used. Specifically, as the light source element, an organic EL (Organic electro-luminesis: OEL) or a laser (Light Amplification by Systemized Emission of Radiation: Laser) may be used.

In FIG. 17, the same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

本実施の形態に係る取付部45と係合溝部34との取付け構造は、係合溝部34に接着剤8を充填するものである。
図17に示すように、取付部45を係合溝部34に接着固定する場合に、硬化した接着剤8が取付部45の鍔部451を抱え込んで保持する。筒部外周面部4501と鍔部上面部453と鍔部外周面部452とにより形成されるくぼみ部分に接着剤8が入り込んで硬化することで接着力が高まるアンカー効果を増大させることができる。
In the mounting structure of the mounting portion 45 and the engaging groove portion 34 according to the present embodiment, the engaging groove portion 34 is filled with the adhesive 8.
As shown in FIG. 17, when the mounting portion 45 is adhesively fixed to the engaging groove portion 34, the cured adhesive 8 holds and holds the flange portion 451 of the mounting portion 45. The adhesive 8 enters and hardens in the recessed portion formed by the outer peripheral surface portion 4501 of the tubular portion, the upper surface portion 453 of the flange portion, and the outer peripheral surface portion 452 of the flange portion, so that the anchor effect of increasing the adhesive force can be increased.

ここで、取付部45を係合溝部34に接着固定する場合、あるいは、カバー4が弾性変形しにくい材料で形成される場合には、第1係合突起部46の厚みを対応する側壁外周部341と側壁内周部340との間隔と同じ寸法としてもよいし、または第1係合突起部46の厚みを対応する側壁外周部341と側壁内周部340との間隔よりも小さい寸法としてもよい。
第1係合突起部46が側壁外周部341と側壁内周部340との間にスムーズに挿入される。第1係合突起部46が側壁外周部341と側壁内周部340との間に挿入されると、第1係合突起部46は、係合溝部34の側壁である側壁外周部341と対向した状態で弾性変形しない。
Here, when the mounting portion 45 is adhesively fixed to the engaging groove portion 34, or when the cover 4 is made of a material that is not easily elastically deformed, the outer peripheral portion of the side wall corresponding to the thickness of the first engaging protrusion portion 46. The dimension may be the same as the distance between the 341 and the inner peripheral portion 340 of the side wall, or the thickness of the first engaging protrusion 46 may be smaller than the distance between the outer peripheral portion 341 of the corresponding side wall and the inner peripheral portion 340 of the side wall. good.
The first engaging protrusion 46 is smoothly inserted between the outer peripheral portion 341 of the side wall and the inner peripheral portion 340 of the side wall. When the first engaging protrusion 46 is inserted between the side wall outer peripheral portion 341 and the side wall inner peripheral portion 340, the first engaging protrusion 46 faces the side wall outer peripheral portion 341 which is the side wall of the engaging groove portion 34.

Embodiment 3.
In this embodiment, the points different from those in the first embodiment will be mainly described.
FIG. 18 is an exploded perspective view of the luminaire 100 according to the third embodiment of the present invention.
FIG. 19 is a diagram showing a mounting structure of the main body portion 3 and the cover 4 according to the third embodiment of the present invention, and is a diagram showing an engaged state between the light source circuit board 60a and the mounting portion 45.
In FIGS. 18 and 19, the same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

本実施の形態に係る取付部45と係合溝部34との取付け構造における第2係合突起部47は、回転方向の移動を規制する回動規制の機能と、本体部3の中心軸に沿う方向の移動を規制する係合の機能とを兼ね備えている。
図18に示すように、本実施の形態に係る照明具100は、光源回路基板60aと、光源回路基板60aの実装面である実装部61に実装される光源素子67とを有する光源部光源部6を備えている。
光源回路基板60aには、ネジ貫通孔65aが形成されている。ネジ貫通孔65aは、光源回路基板60aの周縁部側が閉塞されるように形成されている。
光源回路基板60aには、ネジ貫通孔65aと異なる位置に基板切欠き部68が形成されている。詳しくは、光源回路基板60aの、ネジ貫通孔65aが形成された位置から、回転方向に角度θ1だけ離れた位置に基板切欠き部68が形成されている。基板切欠き部68は光源回路基板60aの周縁部から内側にU字形に凹むように形成されている。
光源回路基板60aの外形は、直径が光源配置部30の直径と略同じ円盤状である。そして、光源部6が光源配置部30に取り付けられた状態では、光源回路基板60aの周縁部は、基板切欠き部68が形成された部分を除いて側壁内周部341に略沿っている。
The second engaging protrusion 47 in the mounting structure of the mounting portion 45 and the engaging groove portion 34 according to the present embodiment has a rotation restricting function for restricting movement in the rotation direction and along the central axis of the main body portion 3. It also has an engagement function that regulates directional movement.
As shown in FIG. 18, the illuminating tool 100 according to the present embodiment has a light source circuit board 60a and a light source unit 67 having a light source element 67 mounted on a mounting unit 61 which is a mounting surface of the light source circuit board 60a. 6 is provided.
A screw through hole 65a is formed in the light source circuit board 60a. The screw through hole 65a is formed so that the peripheral portion side of the light source circuit board 60a is closed.
The light source circuit board 60a is formed with a board notch 68 at a position different from that of the screw through hole 65a. Specifically, the substrate notch portion 68 is formed at a position of the light source circuit board 60a at a position separated by an angle θ1 in the rotation direction from the position where the screw through hole 65a is formed. The substrate notch portion 68 is formed so as to be recessed inward in a U shape from the peripheral edge portion of the light source circuit board 60a.
The outer shape of the light source circuit board 60a is a disk shape having a diameter substantially the same as the diameter of the light source arrangement portion 30. When the light source unit 6 is attached to the light source arrangement unit 30, the peripheral edge portion of the light source circuit board 60a substantially follows the inner peripheral peripheral portion 341 of the side wall except for the portion where the substrate notch portion 68 is formed.

ネジ7は、光源回路基板60aのネジ貫通孔65a、光源配置部30のネジ貫通孔32、蓋部26のネジ貫通部260を貫通し、絶縁部2の第1凸部250に設けられたネジ孔251にねじ込まれる。このネジ7により、光源部6、本体部3、絶縁部2の蓋部26及び筒部20を一体に固定する。
図19に示すように、カバー4が本体部に取り付けられた状態では、取付部45の第2係止突起部47は回動規制凹部に係合している。このとき、本体部3の中心軸方向(矢印Zの方向)において、第2係合突起部47は光源回路基板60aの周縁部と重なっている。重なり寸法はW60である。詳しくは、第2係合突起部47の突起上面部471は、光源回路基板60aの裏面である熱伝達部62と対向している。このため、第2係合突起部47は光源回路基板60aと係合するので、取付部45は、カバー4が本体部3から取り外される向きへの移動が規制される。
The screw 7 penetrates the screw through hole 65a of the light source circuit board 60a, the screw through hole 32 of the light source arrangement portion 30, and the screw penetration portion 260 of the lid portion 26, and is provided on the first convex portion 250 of the insulating portion 2. Screwed into the hole 251. The light source portion 6, the main body portion 3, the lid portion 26 of the insulating portion 2, and the tubular portion 20 are integrally fixed by the screw 7.
As shown in FIG. 19, when the cover 4 is attached to the main body portion, the second locking protrusion 47 of the attachment portion 45 is engaged with the rotation restricting recess. At this time, the second engaging protrusion 47 overlaps with the peripheral edge of the light source circuit board 60a in the direction of the central axis of the main body 3 (direction of arrow Z). The overlapping dimension is W60. Specifically, the protrusion upper surface portion 471 of the second engaging protrusion portion 47 faces the heat transfer portion 62 which is the back surface of the light source circuit board 60a. Therefore, since the second engaging protrusion 47 engages with the light source circuit board 60a, the mounting portion 45 is restricted from moving in the direction in which the cover 4 is removed from the main body portion 3.

本実施の形態の第2係合突起47は、カバー4が本体部3に取り付けられた状態では、回動規制凹部382と係合しているので、カバー4は回転方向の移動が規制される。そして、本実施の形態の第2係合突起47は、カバー4が本体部3に取り付けられた状態では、回動規制凹部382と係合しているので、カバー4は回転しない。
本実施の形態の第2係合突起47は、カバー4が本体部3に取り付けられた状態では、光源回路基板60aと係合しているので、カバー4は本体部3の中心軸に沿った方向の移動が規制される。そして、本実施の形態の第2係合突起47は、本体部3に一度取り付けられたカバー4は、本体部3から外れるおそれがない。
Since the second engaging protrusion 47 of the present embodiment is engaged with the rotation restricting recess 382 when the cover 4 is attached to the main body 3, the cover 4 is restricted from moving in the rotation direction. .. The second engaging projection 47 of the present embodiment is engaged with the rotation restricting recess 382 when the cover 4 is attached to the main body 3, so that the cover 4 does not rotate.
Since the second engaging projection 47 of the present embodiment is engaged with the light source circuit board 60a in a state where the cover 4 is attached to the main body portion 3, the cover 4 is along the central axis of the main body portion 3. Directional movement is restricted. Further, in the second engaging projection 47 of the present embodiment, the cover 4 once attached to the main body portion 3 does not have a possibility of coming off from the main body portion 3.

なお、本実施の形態において、第1係合突起部46を併用することによって、カバー4の本体部3へのより確実な取り付けが可能となる。 In the present embodiment, by using the first engaging protrusion 46 together, the cover 4 can be more securely attached to the main body 3.
