Thereby, when the light source part 6 is attached to the light source arrangement part 30, the light source element 67 is located on the substantially same surface as the upper surface part 347, and the light distribution characteristic of the lamp 100 is improved. If desired light distribution characteristics can be obtained, the light source arrangement part 30 may be provided on the same surface as the upper surface edge part 346 that is the periphery of the upper surface part 347 of the cylindrical part 37, or the upper surface edge part.

It doesn't matter if it's a shape.

図10の(b)(c)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11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11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W13(図10の(b))は、第2凸部252の幅W29(図7の(b)(c))より若干広く形成される。
As shown in FIGS. 10B and 10C, the inside of the cylindrical portion 37 is a hollow portion 378. In the hollow portion 378, the insulating portion 2 in which the power source portion 5 is accommodated is disposed.
As shown to (a) of FIG. 11, the 1st recessed part 360 which the 1st convex part 250 of the insulating part 2 fits in is formed in the inner surface part 36 which is the upper surface which forms the cavity part 378. As shown in FIG. The screw through hole 32 and the screw hole 251 of the insulating portion 2 communicate with each other with the first convex portion 250 fitted in the first concave portion 360.
Further, as shown in FIG. 11B, the inner surface 36 is formed with a second recess 361 into which the second protrusion 252 of the insulating portion 2 is fitted. The second convex portion 252 is fitted into the second concave portion 361 to position the insulating portion 2 in the rotational direction.
The width W13 (FIG. 10B) of the second recess 361 is slightly wider than the width W29 of the second protrusion 252 (FIGS. 7B and 7C).

図11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. 11B, the engagement groove 34 has a side wall 349 on both sides and a bottom 344 provided at the bottom of the side wall 349. The engagement groove 34 has an opening 345 at a position facing the bottom 344. The depth of the engaging groove 34 is L13.
Of the side walls 349 on both sides, the inner side wall 349 is a side wall inner peripheral portion 340, and the outer side wall 349 is a side wall outer peripheral portion 341. The side wall outer peripheral part 341 is an example of the side wall 349 of the engaging groove part 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11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. 11B, the side wall outer peripheral portion 341 is formed so as to be gradually inclined inward from the bottom portion 344 upward. Therefore, the width W26 of the opening 345 is narrower by the width W25 than the width W27 of the bottom 344.
That is, the engagement groove 34 has a slightly narrower upper end (opening end) than the lower end, and the side wall outer periphery 341 of the engagement groove 34 extends from the upper end (opening end) to the lower end. It is slightly inclined to gradually spread 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は係合突起部46の幅W9(図14の(b)参照)以上の寸法であれば部分的に形成されても良い。
In this way, by making the width W27 of the bottom 344 wider than the width W26 of the opening 345, an engagement protrusion 46 of the cover 4 described later is less likely to come out of the engagement groove 34, and is engaged with the engagement groove 34. The protrusion 46 is engaged more securely.
The engaging groove 34 is formed on the entire circumference by secondary processing. Note that the engaging groove 34 may be partially formed as long as it has a dimension equal to or larger than the width W9 of the engaging protrusion 46 (see FIG. 14B).

図8の(a)に示すように、側壁外周部341には、側壁外周部341の直径上において対向する2箇所に、カバー4の取付部45が係合溝部34に挿入される際に係合突起部46を収容するための挿入切欠き部35が形成されている。挿入切欠き部35は、取付部45が係合溝部34に挿入される際に側壁349において係合突起部46に対応する位置に形成されている。   As shown in FIG. 8A, the side wall outer peripheral portion 341 is engaged with the attachment portion 45 of the cover 4 when it is inserted into the engaging groove portion 34 at two locations facing each other on the diameter of the side wall outer peripheral portion 341. An insertion cutout 35 for accommodating the mating protrusion 46 is formed. The insertion notch 35 is formed at a position corresponding to the engagement protrusion 46 on the side wall 349 when the attachment 45 is inserted into the engagement groove 34.

また、側壁内周部340には、対向する2箇所に、上述したネジ貫通孔32が形成される。ネジ貫通孔32は側壁内周部340から内側に凹むように形成される。
図8の(a)及び図9の(a)に示すように、係合溝部34では、挿入切欠き部35とネジ貫通孔32とが対向するように配置される。
Further, the above-described screw through-holes 32 are formed in two opposite locations on the side wall inner periphery 340. The screw through-hole 32 is formed to be recessed inward from the side wall inner periphery 340.
As shown in FIGS. 8A and 9A, in the engaging groove 34, the insertion notch 35 and the screw through hole 32 are arranged to face each other.

挿入切欠き部35は、側壁外周部341が外側に凹むように切り欠かれて形成される。
図12の(b)示すように、挿入切欠き部35は、側壁外周部341が切り欠かれた部分の最奥部に形成される切欠き外周部350と、切り欠かれた部分の側部である切欠き側壁部353と、切り欠かれた部分の底部である切欠き底部354とを有する。また、切欠き外周部350と対向する位置は切欠き開口部355となる。
切欠き外周部350は、上端より略垂直に形成された第1外周部351と、第1外周部351の下端から内側に向かって傾斜した第2外周部352とを有する。なお、切欠き外周部350は、上端より略垂直に形成された第1外周部351のみから構成されていてもよい。
The insertion cutout portion 35 is formed by cutting out so that the side wall outer peripheral portion 341 is recessed outward.
As shown in FIG. 12 (b), the insertion notch 35 includes a notch outer periphery 350 formed at the innermost part of the portion where the side wall outer periphery 341 is notched, and a side portion of the notch. A cut-out side wall portion 353 and a cut-out bottom portion 354 which is a bottom portion of the cut-out portion. Further, a position facing the notch outer peripheral part 350 is a notch opening 355.
The notched outer peripheral part 350 has a first outer peripheral part 351 formed substantially perpendicular to the upper end, and a second outer peripheral part 352 inclined inward from the lower end of the first outer peripheral part 351. Note that the notched outer peripheral portion 350 may be configured only by the first outer peripheral portion 351 formed substantially perpendicular to the upper end.

以上のように、挿入切欠き部35は、係合溝部34の側壁外周部341に凹状に形成される。図11の(a)示すように、挿入切欠き部35の切欠き底部354は、係合溝部34の底部344よりも外側にW24だけ広がっている。また、挿入切欠き部35の幅W14は、係合突起部46の幅W9より広く形成される(W14>W9)。

15A and 15B are views showing the cover 4 according to the present embodiment, in which FIG. 15A is a front view, FIG. 15B is a side view, FIG. 15C is a cross-sectional view along line BB in FIG. It is CC sectional drawing of (b).
FIG. 16 is a view showing the cover 4 according to the present embodiment, and is an enlarged perspective view of a C part in FIG.

図1〜図4及び図13から図16を用いて、カバー4の構成について説明する。
カバー4は、光源部6を覆った状態で本体部3に取り付けられる。カバー4は、光透過部、透光部、光拡散部、グローブともいう。
カバー4は、本体部3と比較して熱伝導率が小さい樹脂材料を用いて形成されることが好ましい。灯具100は、外殻部に占めるカバー4の割合が比較的大きいため、使用者は灯具100を照明器具200に取り付けたり取りはずしたりするときにカバー4を握ることが想定される。カバー4が本体部3と比較して熱伝導率が小さい樹脂材料を用いて形成されることにより、使用者が、消灯直後に灯具100に触れた場合でも不快感を覚えることがない。また、火傷など怪我のリスクも大幅に低減させることができる。
カバー主部40は、光透過性の材料を含んで形成されている。また、カバー主部40は、光拡散性の材料を含んで形成されていてもよい。
The configuration of the cover 4 will be described with reference to FIGS. 1 to 4 and FIGS. 13 to 16.
The cover 4 is attached to the main body 3 in a state where the light source 6 is covered. The cover 4 is also referred to as a light transmission part, a light transmission part, a light diffusion part, or a globe.
The cover 4 is preferably formed using a resin material having a lower thermal conductivity than the main body 3. Since the ratio of the cover 4 occupying the outer shell portion of the lamp 100 is relatively large, it is assumed that the user holds the cover 4 when attaching or removing the lamp 100 to the lighting apparatus 200. By forming the cover 4 using a resin material having a lower thermal conductivity than that of the main body 3, the user does not feel uncomfortable even when the user touches the lamp 100 immediately after it is turned off. In addition, the risk of injury such as burns can be greatly reduced.
The cover main part 40 is formed including a light transmissive material. Moreover, the cover main part 40 may be formed including a light diffusing material.

カバー4は、カバー主部40と、下端部44と、取付部45とを備える。カバー主部40と下端部44と取付部45とは、一つの部品で構成されることが好ましい。
カバー4は、ブロー成形法(中空成形法)、射出成形法の他、付加製造技術(Additive Manufacturing Technology)を用いて形成されてもよい。
カバー主部40は、取付部45の根元から膨らむように形成され、本体部3の光源配置部30を覆う。カバー主部40は、第1主部41と第2主部42とを備える。
The cover 4 includes a cover main portion 40, a lower end portion 44, and an attachment portion 45. The cover main portion 40, the lower end portion 44, and the attachment portion 45 are preferably formed of a single component.
The cover 4 may be formed by using an additive manufacturing technology in addition to the blow molding method (hollow molding method) and the injection molding method.
The cover main part 40 is formed so as to swell from the base of the attachment part 45 and covers the light source arrangement part 30 of the main body part 3. The cover main part 40 includes a first main part 41 and a second main part 42.

図4の(a)に示すように、第1主部41は、曲率R1で外側に膨らんだ形状である。第2主部42は、曲率R2で内側に窄んだ形状である。カバー4が本体部3に取り付けられると、第2主部42は本体部3の第1錐状部370と連続し、第2主部42から第1錐状部370にかけて、曲率R2で滑らかに窄んだ形状を成す。   As shown to (a) of FIG. 4, the 1st main part 41 is the shape which swelled outside with the curvature R1. The second main portion 42 has a shape constricted inward with a curvature R2. When the cover 4 is attached to the main body part 3, the second main part 42 is continuous with the first conical part 370 of the main body part 3, and smoothly from the second main part 42 to the first conical part 370 with a curvature R2. It has a constricted shape.

下端部44は、カバー4が本体部3に取り付けられる際に、本体部3の上面部347と接する部分である。
図15に示すように、下端部44の最大外径W2は、カバー主部40の最大外径W1よりも小さく形成される。また、下端部44の最大外径W2は、本体部3の最大外径W11(図10の(a)等参照)と略同一であることが好ましい。
図14の(b)に示すように、下端部44には、最大外径W10の開口部440が形成される。カバー4が本体部3に取り付けられると、開口部440の位置に光源部6が配置されるため、カバー主部40により光源部6が覆われる。
The lower end portion 44 is a portion that contacts the upper surface portion 347 of the main body portion 3 when the cover 4 is attached to the main body portion 3.
As shown in FIG. 15, the maximum outer diameter W2 of the lower end portion 44 is formed smaller than the maximum outer diameter W1 of the cover main portion 40. Moreover, it is preferable that the maximum outer diameter W2 of the lower end portion 44 is substantially the same as the maximum outer diameter W11 of the main body portion 3 (see FIG. 10A, etc.).
As shown in FIG. 14B, the lower end 44 is formed with an opening 440 having a maximum outer diameter W10. When the cover 4 is attached to the main body unit 3, the light source unit 6 is disposed at the position of the opening 440, so that the light source unit 6 is covered by the cover main unit 40.

取付部45は、開口部440の周縁から筒状に突き出した形状である。取付部45は、本体部3の係合溝部34に挿入される。取付部45の最大外径W7は、カバー主部40の最大外径W1よりも小さく形成される。また、取付部45の最大外径W7は、下端部44の最大外径W2よりも小さく形成される。   The attachment portion 45 has a shape protruding in a cylindrical shape from the periphery of the opening 440. The attachment portion 45 is inserted into the engagement groove portion 34 of the main body portion 3. The maximum outer diameter W7 of the attachment portion 45 is formed smaller than the maximum outer diameter W1 of the cover main portion 40. Further, the maximum outer diameter W7 of the attachment portion 45 is formed smaller than the maximum outer diameter W2 of the lower end portion 44.

取付部45は、下端部44から突き出た筒部450と、筒部450の下端部から外側に突き出した鍔部451とを有する。本実施の形態においては、鍔部451は無くても構わない。なお、取付部45の最大外径W7は、鍔部451の最大外径を指すものとする。
カバー主部40は、取付部45と一体に形成されると共に、最大外径W1が取付部45の最大外径W7より大きい。
The attachment portion 45 includes a cylindrical portion 450 protruding from the lower end portion 44 and a flange portion 451 protruding outward from the lower end portion of the cylindrical portion 450. In the present embodiment, the flange 451 may not be provided. Note that the maximum outer diameter W7 of the attachment portion 45 indicates the maximum outer diameter of the flange portion 451.
The cover main portion 40 is formed integrally with the attachment portion 45, and the maximum outer diameter W1 is larger than the maximum outer diameter W7 of the attachment portion 45.

図16に示すように、取付部45は、筒部450と鍔部451とを有する。筒部450の外周面である筒部外周面部4501は、取付部45の筒状の周面の一例である。
取付部45の鍔部451は、鍔部451の外周面となる鍔部外周面部452と、筒部450から立ち上がり鍔部外周面部452に連続する鍔部上面部453と、鍔部下面部459とを有する。
As shown in FIG. 16, the attachment portion 45 includes a tube portion 450 and a flange portion 451. A cylinder part outer peripheral surface part 4501 that is an outer peripheral surface of the cylinder part 450 is an example of a cylindrical peripheral surface of the attachment part 45.
The flange portion 451 of the attachment portion 45 includes a flange outer peripheral surface portion 452 that is an outer peripheral surface of the flange portion 451, a flange upper surface portion 453 that rises from the cylindrical portion 450 and continues to the flange outer peripheral surface portion 452, and a flange lower surface portion 459. Have

取付部45は、筒状の周面である筒部外周面部4501から突き出した係合突起部46であって弾性体により形成された係合突起部46を有する。
係合突起部46は、係合溝部34に挿入された状態で、係合溝部34の側壁である側壁外周部341と対向し、側壁外周部341により弾性変形される。
係合突起部46では、弾性変形をする材料、形状が決定される。また、係合突起部46は、側壁外周部341よりも柔らかい材料が好適である。
The attachment portion 45 has an engagement protrusion 46 that is an engagement protrusion 46 that protrudes from a cylinder outer peripheral surface 4501 that is a cylindrical peripheral surface and is formed of an elastic body.
The engagement protrusion 46 is opposed to the side wall outer peripheral portion 341 that is the side wall of the engagement groove portion 34 while being inserted into the engagement groove 34, and is elastically deformed by the side wall outer peripheral portion 341.
In the engagement protrusion 46, the material and shape that are elastically deformed are determined. The engaging protrusion 46 is preferably made of a material softer than the side wall outer peripheral portion 341.

係合突起部46は、筒部外周面部4501及び鍔部外周面部452から外側に突き出している。
図16に示すように、係合突起部46は、筒部外周面部4501から立ち上がる突起上面部467と、筒部外周面部4501及び鍔部外周面部452から立ち上がる一対の突起側面部468と、係合突起部46の外周面である突起外周面部465と、突起下面部469とを有する。突起外周面部465は、下方に向かって広がるように傾斜する。突起外周面部465と突起下面部469との境界が、係合突起部46において最も外側に突き出た突起先端部466である。突起下面部469は、鍔部下面部459から突起先端部466に向かって滑らかな曲面を成す。
なお、突起先端部466が鍔部下面部459と同じ高さにあり、突起下面部469が鍔部下面部459と連続する平面状であってもよい。
The engaging protrusion 46 protrudes outward from the outer peripheral surface portion 4501 and the outer peripheral surface portion 452 of the flange portion.
As shown in FIG. 16, the engaging protrusion 46 is engaged with a protrusion upper surface portion 467 rising from the outer peripheral surface portion 4501 of the cylinder portion, and a pair of protrusion side surface portions 468 rising from the outer peripheral surface portion 4501 of the cylindrical portion and the flange outer peripheral surface portion 452. A protrusion outer peripheral surface portion 465 that is an outer peripheral surface of the protrusion portion 46 and a protrusion lower surface portion 469 are provided. The protrusion outer peripheral surface portion 465 is inclined so as to expand downward. A boundary between the protrusion outer peripheral surface portion 465 and the protrusion lower surface portion 469 is a protrusion tip portion 466 protruding outward in the engagement protrusion portion 46. The protrusion lower surface portion 469 forms a smooth curved surface from the flange lower surface portion 459 toward the protrusion tip portion 466.
The protrusion tip 466 may be in the same height as the flange lower surface 459, and the protrusion lower surface 469 may be planar and continuous with the flange lower surface 459.

取付部45は、周面に係合突起部46を少なくとも2つ有する。図14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、鍔部451の最大外径W7は、係合突起部46を含めた取付部45の最大外径W6より若干小さくなる。
係合突起部46を収容する本体部3の挿入切欠き部35は、取付部45が係合溝部34に挿入される際に側壁349において係合突起部46に対応する位置に形成される。
The attachment portion 45 has at least two engagement protrusions 46 on the peripheral surface. As shown in FIG. 14B, the mounting portion 45 is provided at two locations facing each other on the cylindrical diameter. Therefore, the maximum outer diameter W7 of the flange portion 451 is slightly smaller than the maximum outer diameter W6 of the attachment portion 45 including the engagement protrusion 46.
The insertion notch 35 of the main body 3 that accommodates the engagement protrusion 46 is formed at a position corresponding to the engagement protrusion 46 on the side wall 349 when the attachment portion 45 is inserted into the engagement groove 34.

図13に示すように、カバー4は、係合突起部46の上部のカバー主部40の表面に、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、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。灯具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. 13, the cover 4 has a guide mark 43 indicating the position of the engaging protrusion 46 on the surface of the cover main part 40 above the engaging protrusion 46. The guide mark 43 is a mark for allowing the operator to recognize the position of the engaging protrusion 46. In consideration of the optical performance and design of the lamp 100, the guide mark 43 is preferably provided near the lower end 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, stamped, or the like.

<Attaching structure of main body 3 and cover 4>
FIG. 17 is a view showing a mounting structure between the main body 3 and the cover 4 according to the present embodiment, and FIG. 17A is a view showing a state in which the engagement protrusion 46 is inserted into the insertion notch 35. FIG. 6B is a diagram illustrating a state in which the engaging protrusion 46 is inserted into the insertion notch 35.
FIG. 18 is a view showing a mounting structure between the main body 3 and the cover 4 according to the present embodiment, and shows a state in which the cover 4 is rotated after the engaging protrusion 46 is inserted into the insertion notch 35. It is.

図17及び図18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により係合突起部46の位置を確認し、係合突起部46を本体部3の係合溝部34の挿入切欠き部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17の(a)(b)は(1)の手順を示している。
このとき、図17の(b)に示すように、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、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、カバー中心軸から係合突起部46の外周までの最短距離は、本体中心軸から挿入切欠き部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。
A procedure for attaching the main body 3 and the cover 4 will be described with reference to FIGS. 17 and 18.
(1) The operator confirms the position of the engaging protrusion 46 with the guide mark 43, and adjusts the engaging protrusion 46 to the position of the insertion notch 35 of the engaging groove 34 of the main body 3. 45 is inserted into the engaging groove 34. 17A and 17B show the procedure of (1).
At this time, as shown in FIG. 17B, the protrusion outer peripheral surface portion 465 of the engaging protrusion portion 46 is located outside the side wall outer peripheral portion 341 of the engaging groove portion 34. That is, the thickness of the engaging protrusion 46 is larger than the interval 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 engaging protrusion 46 at the lower end of the mounting portion 45 is shorter than the shortest distance from the main body central axis to the notch outer periphery 350 that is the outer wall of the insertion notch 35. Somewhat small. Further, the shortest distance from the cover central axis to the outer periphery of the engaging protrusion 46 at the lower end of the mounting portion 45 is slightly larger than the shortest distance from the main body central axis to the side wall outer peripheral portion 341 of the engaging groove 34.

(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。
この回転により、係合突起部46は、本体部3の係合溝部34における挿入切欠き部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。図18は(2)の手順後を示している。
(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 rotate the main body 3 in the T2 direction.
By this rotation, the engaging protrusion 46 moves from the position of the insertion notch 35 in the engaging groove 34 of the main body 3 to a position sandwiched between the side wall outer peripheral part 341 and the side wall inner peripheral part 340. FIG. 18 shows the procedure after step (2).

上述したように、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、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。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、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により弾性変形される。   As described above, since the thickness of the engaging protrusion 46 is larger than the distance between the side wall outer peripheral part 341 and the side wall inner peripheral part 340, the engaging protrusion 46 is located between the side wall outer peripheral part 341 and the side wall inner peripheral part 340. It is press-fitted into. When the engaging protrusion 46 is press-fitted between the side wall outer peripheral portion 341 and the side wall inner peripheral portion 340, the engaging protrusion 46 is in the state facing the side wall outer peripheral portion 341 that is the side wall of the engaging groove portion 34. Is elastically deformed.

図18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、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. 18, the protrusion outer peripheral surface portion 465 is pressed in the P direction by the side wall outer peripheral portion 341 of the engagement groove portion 34. That is, 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 engagement groove portion 34 in a state where the engagement protrusion 46 is slightly elastically deformed. 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 engagement protrusion 46 is locked by the engagement groove 34, and the cover 4 is in close contact with the main body 3.

以上のように、カバー4の取付部45が、挿入切欠き部35に係合突起部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、係合突起部46は、取付部45の回転にしたがって挿入切欠き部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。
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は係合突起部46よりも硬い材料であることが好適である。
As described above, the attachment portion 45 of the cover 4 is inserted into the engagement groove portion 34 while accommodating the engagement protrusion 46 in the insertion cutout portion 35, and thus the circumferential direction (also referred to as the groove direction) of the engagement groove portion 34. ), The engaging protrusion 46 moves from the position of the insertion notch 35 to a position facing the side wall outer peripheral portion 341 which is a side wall as the mounting portion 45 rotates.
Since the engaging protrusion 46 is elastically deformed by the side wall outer peripheral part 341 at a position facing the side wall outer peripheral part 341, it is preferable that at least the side wall outer peripheral part 341 is made of a material harder than the engaging protruding part 46.

<灯具100の形状について>
次に、図4を用いて、灯具100の形状について説明する。
本実施の形態に係る灯具100は、例えば、全配光(広配光)特性220°と、一般的な白熱電球(エジソン電球)と完全同一フォルムとを併せ持つ電球形LEDランプであり、その形状は以下の通りである。
(a)カバー主部40の高さ寸法L2は、灯具100の高さ寸法L1の50%以上である。
(b)本体部3の高さ寸法L3は、灯具100の高さ寸法L1の25%以下である。
(c)カバー主部40の高さ寸法L2は、本体部3の高さ寸法L3より大きい。
(d)本体部3の高さ寸法L3は、カバー主部40の高さ寸法の50%以下である。
(e)カバー主部40の最大径寸法W1は、本体部3の最大径寸法W11より大きい。
(f)本体部3の最大径寸法W11は、カバー主部40の最大径寸法W1の70%以下である。
(g)カバー主部40の包絡体積は、本体部3の包絡体積より大きい。
(h)口金側から見た(下面視における)カバー主部の投影面積は50%以上である。これにより、口金側への配光が向上する。
(i)口金側から見た(下面視における)本体部3の投影面積は20%以下である。これにより、口金側への配光が向上する。
(j)光源部6(発光部)がカバー主部40の下端部と同じ高さになる位置に配置(実装)される。
(k)光源部6(発光部)の発光中心(光源)は本体部3の最小径領域の120%以内の領域に配置される。これにより、口金側への配光が向上する。
なお、実施の形態に係る灯具100は、上述のように、灯具(電球形照明ランプ)全体における本体部の占める高さ寸法の割合が低く抑えられている。よって、本体部の筒部内部の収容部に収容される絶縁部について、蓋部の厚さ寸法を最小化(フィルム化、シート化)することによって、電源部が収納される絶縁部の筒部の容積を確保しながら本体部の高さ寸法を小さくすることができる。
<About the shape of the lamp 100>
Next, the shape of the lamp 100 will be described with reference to FIG.
The lamp 100 according to the present embodiment is, for example, a light bulb-shaped LED lamp having a total light distribution (wide light distribution) characteristic of 220 °, a general incandescent light bulb (Edison light bulb), and a completely identical form. Is as follows.
(A) The height dimension L2 of the cover main portion 40 is 50% or more of the height dimension L1 of the lamp 100.
(B) The height dimension L3 of the main body portion 3 is 25% or less of the height dimension L1 of the lamp 100.
(C) The height dimension L2 of the cover main part 40 is larger than the height dimension L3 of the main body part 3.
(D) The height dimension L3 of the main body part 3 is 50% or less of the height dimension of the cover main part 40.
(E) The maximum diameter W1 of the cover main portion 40 is larger than the maximum diameter W11 of the main body 3.
(F) The maximum diameter dimension W11 of the main body part 3 is 70% or less of the maximum diameter dimension W1 of the cover main part 40.
(G) The envelope volume of the cover main part 40 is larger than the envelope volume of the main body part 3.
(H) The projected area of the cover main part (in the bottom view) viewed from the base side is 50% or more. Thereby, the light distribution to the base side is improved.
(I) The projected area of the main body portion 3 (in the bottom view) viewed from the base side is 20% or less. Thereby, the light distribution to the base side is improved.
(J) The light source unit 6 (light emitting unit) is disposed (mounted) at the same height as the lower end of the cover main unit 40.
(K) The light emission center (light source) of the light source unit 6 (light emitting unit) is arranged in a region within 120% of the minimum diameter region of the main body unit 3. Thereby, the light distribution to the base side is improved.

***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灯具100では、取付部45の係合突起部46が本体部3の挿入切欠き部35に沿うように中心軸方向に挿入され、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を中心軸を基準に回転させる。そして、係合突起部46が挿入切欠き部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の係合突起部46が若干弾性変形した状態となっており、係合突起部46の弾性力によって係合突起部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、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。
*** Explanation of effects of this embodiment ***
As described above, in the lamp 100 according to the present embodiment, the engagement protrusion 46 of the attachment portion 45 is inserted in the central axis direction along the insertion notch 35 of the main body 3, and the cover 4 is attached to the main body. The cover 4 or the main body 3 is rotated with respect to the central axis while being pressed against the center 3. Then, the rotation is stopped at the position where the engagement protrusion 46 has moved from the insertion notch 35 to the engagement groove 34. As described above, when the cover 4 is attached to the main body 3, the engagement protrusion 46 of the attachment 45 is slightly elastically deformed, and the engagement protrusion 46 is caused by the elastic force of the engagement protrusion 46. The protrusion tip portion 466 is pressed against the side wall outer peripheral portion 341 of the engagement groove portion 34 that is slightly inclined. At this time, the cover 4 receives the reaction force of the slightly inclined side wall outer peripheral portion 341, so that the engaging projection 46 is pushed back toward the lower end of the engaging groove 34 of the main body 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 be detached from the main body 3.

また、本実施の形態に係る灯具100では、灯具(電球形照明ランプ)全体における本体部(ヒートシンク)の占める割合が低く抑えられているので、灯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灯具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 lamp 100 according to the present embodiment, since the proportion of the main body (heat sink) in the entire lamp (bulb-shaped illumination lamp) is suppressed, the lamp can be reduced in weight. On the other hand, since the cover becomes relatively large, the cover becomes heavy and needs to be securely attached to the main body portion that becomes relatively small. Therefore, according to the attachment structure of the cover and the main body portion of the lamp 100 according to the present embodiment, the lamp 100 can be more reliably attached and may come off from the main body portion even if the cover attached to the main body portion becomes relatively heavy. Absent.

上側グローブと下側グローブとの2つの部品で構成される場合、ローブ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、異なる形の別々のグローブ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。異なる形のグローブ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。組立工程にグローブ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灯具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グローブは、照明装置(ランプ)にとって最も重要な部品であり、グローブ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灯具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灯具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 the upper glove and the lower glove are composed of two parts, they are divided into upper and lower parts at the maximum diameter portion of the lobe, so that they need to be fixed by ultrasonic welding or vibration welding. In addition, it is necessary to use different gloves of different shapes, which may increase the material cost of the parts. It is necessary to use separate molds to form different shaped gloves, which may increase mold costs. It is necessary to provide a process for fixing the glove in the assembly process, which complicates the assembly process and requires time and effort to maintain and manage the quality of the fixation, and problems remain in terms of manufacturing cost and manufacturing quality.
On the other hand, in the lamp 100 according to the present embodiment, since the cover main portion and the attachment portion are formed of one component, the manufacturing cost can be reduced and the manufacturing quality can be improved.
In addition, the globe, which is an exterior design component and an optical component that transmits light, is the most important component for a lighting device (lamp), and the method of leaving a sticking mark on the surface of the globe may impair the design and optical characteristics. There is. On the other hand, in the lamp 100 according to the present embodiment, the cover main portion and the attachment portion are formed of a single component, so there is no risk of impairing the design and optical characteristics.
As described above, according to the lamp 100 according to the present embodiment, the cover and the main body can be reliably joined with a simple configuration, so that the manufacturing cost can be reduced. In addition, since the cover is formed of a single component, the manufacturing quality is improved and the design and optical characteristics are not impaired.

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(広配光)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、灯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、少なくとも灯具に通電させているときには、カバーが落下しない。
The portion where the cover mounting portion and the main body portion are attached has a diameter smaller than the maximum diameter of the cover, and the light source element (LED) is disposed (mounted) on the light source arrangement portion formed in the portion covered by the cover of the main body portion (heat sink). ) Therefore, in order to obtain a total light distribution (wide light distribution) characteristic, the light source element (LED) is preferably disposed (mounted) on the outer edge side as much as possible. For this reason, it is necessary to attach an attaching part to the extremely limited area | region of the outer edge part of the light source arrangement | positioning part.
According to the mounting structure of the cover and the mounting portion according to the present embodiment, the engaging protrusion protruding from the peripheral surface of the mounting portion is elastically deformed and brought into close contact with the outer peripheral portion of the side wall of the engaging groove. Can be reduced to increase the area of the light source arrangement portion.
For example, if the size of the cover with respect to the main body is adjusted in an environment of 25 degrees Celsius or more and the cover is slightly expanded when the lamp is lit, the cover is not energized at least when the lamp is energized. Does not fall.

***他の構成***
本実施の形態では、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、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、係合突起部が取付部の内側の周面から突出する場合、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、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、係合突起部が取付部の両側の周面から突出する場合、係合突起部を側壁外周部に形成された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、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。
