Description

本発明は、電球型ＬＥＤランプに取り付けるセードおよびこのセードを用いた照明器具に関するものである。   The present invention relates to a shade attached to a bulb-type LED lamp and a lighting apparatus using the shade.

従来より、器具自体のコンパクト化およびセードを光源に近づければ近づける程、配光制御が容易になることから、ソケットにねじ込まれる電球に直接取り付けるセードが提案されている（例えば、特許文献１参照）。
図８に示すように、特許文献１に記載のセード１００は、電球形蛍光灯１０１に取り付けられる。電球形蛍光灯１０１は、ソケット（図示省略）にねじ込まれる口金１０２に続いて、内部に点灯装置（図示省略）等を収容するカバー１０３が設けられ、カバー１０３の先端に、内部に光源（図示省略）を収容するグローブ１０４を有する。 Conventionally, the closer the instrument is made compact and the shade is closer to the light source, the easier the light distribution control becomes. Therefore, a shade attached directly to a light bulb screwed into a socket has been proposed (see, for example, Patent Document 1). ).
As shown in FIG. 8, the shade 100 described in Patent Document 1 is attached to a bulb-type fluorescent lamp 101. The bulb-type fluorescent lamp 101 is provided with a cover 103 for accommodating a lighting device (not shown) and the like inside a base 102 screwed into a socket (not shown). A light source (not shown) is provided at the tip of the cover 103. (Not shown).

カバー１０３は、口金１０２に連続して、グローブ１０４側に向かって拡径する筒状部１０５を有し、さらに段部１０６を介して円錐部１０７を有する。この円錐部１０７に連続してグローブ１０４が設けられている。   The cover 103 has a cylindrical part 105 that is continuous with the base 102 and expands toward the globe 104 side, and further has a conical part 107 through a step part 106. A globe 104 is provided continuously to the conical portion 107.

セード１００は、上板である円板部１０９の中心部に、電球形蛍光灯１０１の段部１０６の外形よりも小さめな内径の丸孔形状の開口（図示省略）を有しており、この開口を段部１０６に引っ掛けて取り付けられる。また、セード１００は、円板部１０９から下方に円錐台形状に拡径して延びる反射笠部１０８を有しており、電球形蛍光灯１０１が発した光を所定の方向および範囲に反射する。
なお、セード１００は板金製である。 The seed 100 has a round hole-shaped opening (not shown) having an inner diameter smaller than the outer shape of the step portion 106 of the bulb-type fluorescent lamp 101 at the center of the disc portion 109 which is an upper plate. The opening is hooked onto the step 106 and attached. The shade 100 has a reflective shade portion 108 that extends downward from the disc portion 109 in a truncated cone shape, and reflects light emitted from the bulb-type fluorescent lamp 101 in a predetermined direction and range. .
The shade 100 is made of sheet metal.

実用新案登録第３１４３３２６号公報（第１図）Utility Model Registration No. 3143326 (Fig. 1)

一般に、セードによるより精度の高い配光制御は、セードが光源に近ければ近いほど達成されるが、前述したような電球形蛍光灯を用いる場合には、それ自身が高温となるため、空間を設けて電球からの熱によるセードの変形を抑えることが行われている。
セードに対する熱の影響は、発熱量が小さなＬＥＤ電球を用いることにより、ある程度減少されると考えられるが、近年のＬＥＤ電球の高出力化に伴って発熱量が大きくなっているため、同様の熱対策が要求される。
このため、空間を設けて熱の影響を避ける場合には、セードおよび照明器具のコンパクト化を妨げるという問題があった。
また、熱を考慮した材質の取付部品を別途設ける場合には、部品点数の増加によるコストアップを招くという問題があった。 In general, more accurate light distribution control by shade is achieved as the shade is closer to the light source. However, when using a bulb-type fluorescent lamp as described above, the temperature of the bulb itself becomes high, so that space is reduced. It is provided to suppress the deformation of the shade by heat from the light bulb.
The effect of heat on the shade is thought to be reduced to some extent by using LED bulbs that generate a small amount of heat, but the amount of heat generated increases with the recent increase in output of LED bulbs. Countermeasures are required.
For this reason, when providing space and avoiding the influence of heat, there existed a problem of preventing the compactization of a shade and a lighting fixture.
In addition, when a mounting part made of a material that takes heat into consideration is separately provided, there is a problem in that the cost increases due to an increase in the number of parts.

本発明は、従来の問題を解決するためになされたもので、光源に近づけることができるとともに、部品点数を減少させてコストダウンを図ることができるセードおよびこのセードを用いた照明器具を提供することを目的とする。   The present invention has been made in order to solve the conventional problems, and provides a shade that can be brought close to a light source and that can reduce the number of parts to reduce the cost, and a lighting apparatus using the shade.

また、本発明のセードは、前記笠部の内側に、前記電球型ＬＥＤランプからの光を前記隙間部に向けて反射させる反射部を有するものである。   Moreover, the shade of this invention has a reflection part which reflects the light from the said bulb-type LED lamp toward the said clearance gap inside the said shade part.

また、本発明のセードは、前記支持部と前記反射部とを連結する複数の第１連結竿と、前記反射部と前記笠部とを連結する複数の第２連結竿と、を有するものである。   The shade of the present invention includes a plurality of first connecting rods that connect the support portion and the reflecting portion, and a plurality of second connecting rods that connect the reflecting portion and the cap portion. is there.

また、本発明のセードは、前記第１連結竿と前記第２連結竿とが、平面視で上から見たときに一直線上、かつ、放射状に設けられているものである。   In the shade of the present invention, the first connecting rod and the second connecting rod are provided in a straight line and radially when viewed from above in a plan view.

また、本発明のセードは、前記電球型ＬＥＤランプと前記支持部との間に、環状部材を介在させたものである。   Moreover, the shade of this invention interposes the annular member between the said lightbulb type LED lamp and the said support part.

また、本発明のセードは、前記環状部材が、弾性材料で形成されているものである。   In the shade of the present invention, the annular member is made of an elastic material.

また、本発明のセードは、前記環状部材が、透光性材料で形成されているものである。   In the shade of the present invention, the annular member is formed of a translucent material.

本発明は、セードの支持部を、電球型ＬＥＤランプのランプ本体により支持するので、セードを取り付ける部品を別途設ける必要が無く、部品点数を減少させてコストダウンを図ることができる。このとき、ランプ本体が、口金側から発光部側に向かって拡径するテーパ面を有するので、容易に支持部を支持することができる。また、支持部の周囲に笠部が設けられているので、笠部は、電球型ＬＥＤランプに近づけて取り付けることができ、精度の高い配光制御が可能になるという効果を有するセードおよび照明器具を提供できる。   In the present invention, since the support portion of the shade is supported by the lamp body of the bulb-type LED lamp, there is no need to separately provide a component for attaching the shade, and the number of components can be reduced and the cost can be reduced. At this time, since the lamp body has a tapered surface whose diameter increases from the base side toward the light emitting part side, the support part can be easily supported. In addition, since the shade portion is provided around the support portion, the shade portion can be attached close to the light bulb type LED lamp, and the shade and the lighting apparatus having an effect that the light distribution control with high accuracy is possible.

なお、以下の説明において、照射方向を下方とする。 (First embodiment)
Hereinafter, the shade and lighting fixture of 1st Embodiment which concern on this invention are demonstrated using drawing.
As shown in FIG. 1 and FIG. 2, the luminaire 10 according to the embodiment of the present invention can be used to illuminate a lower portion or the like by hanging from a ceiling or the like.
The lighting fixture 10 has a cord 11 suspended from a ceiling or the like, and a socket 12 is attached to the lower end of the cord 11. A light bulb type LED lamp (hereinafter referred to as an LED light bulb) 20 is detachably attached to the socket 12, and a shade 30 is attached to the LED light bulb 20.
In the following description, the irradiation direction is the downward direction.

図３に示すように、ＬＥＤ電球２０は、ソケット１２にねじ込んで装着されて点灯電力の供給を受ける口金２１を有する。口金２１の下側には、一端（図３において上端）が取り付けられるランプ本体２２を有し、ランプ本体２２の他端（図３において下端）には、内部にＬＥＤ２３１を収容した発光部２３が取り付けられる。   As shown in FIG. 3, the LED bulb 20 has a base 21 that is screwed into the socket 12 and receives lighting power. A lamp body 22 to which one end (upper end in FIG. 3) is attached is provided below the base 21, and a light emitting unit 23 that accommodates an LED 231 is provided at the other end (lower end in FIG. 3) of the lamp body 22. It is attached.

ランプ本体２２は、口金側である上端から発光部側である下端に向かって直線的に拡径しており、円錐台形状（テーパ面）を呈している。
なお、図４に示すように、ランプ本体２２Ｂが、直線的ではなく、内側に凹んだ曲線形状で拡径するＬＥＤ電球２０Ｂの場合も含む。
以下の説明においては、図３に示すＬＥＤ電球２０を用いる場合について説明する。 The lamp body 22 linearly increases in diameter from the upper end on the base side toward the lower end on the light emitting part side, and has a truncated cone shape (tapered surface).
In addition, as shown in FIG. 4, the case where the lamp main body 22B is not linear but includes an LED bulb 20B that expands in a curved shape recessed inward is included.
In the following description, the case where the LED bulb 20 shown in FIG. 3 is used will be described.

図５（Ａ）および（Ｂ）に示すように、前述したＬＥＤ電球２０に取り付けられるセード３０は、ＬＥＤ電球２０のランプ本体２２に支持される支持部３１と、支持部３１の周囲に設けられる笠部３２を有する。
支持部３１は、円形リング状を呈しており、笠部３２は、下方に向かって拡径する略円錐台形状を呈している。 As shown in FIGS. 5A and 5B, the shade 30 attached to the LED bulb 20 described above is provided around the support portion 31 supported by the lamp body 22 of the LED bulb 20 and the support portion 31. It has a cap portion 32.
The support portion 31 has a circular ring shape, and the cap portion 32 has a substantially truncated cone shape whose diameter increases downward.

支持部３１と笠部３２との間には、隙間部３３が設けられており、笠部３２の内側には、ＬＥＤ電球２０からの光を隙間部３３に向けて反射させる反射部３４を有する。
反射部３４は、下方に向かって縮径し、上下に開口した略円錐台形状をしており、内面は光を反射する反射面を有する。
これにより、図１（Ａ）および（Ｂ）に示すように、ＬＥＤ電球２０から下向きに発せられた光は、下方に照射される（図１（Ａ）および（Ｂ）中矢印Ａ）。また、ＬＥＤ電球２０から側方に発せられた光は、反射部３４により上方へ反射されて、隙間部３３を通って上方の天井側へ照射される（図１（Ａ）および（Ｂ）中矢印Ｂ）。さらに、ＬＥＤ電球２０から上方へ発せられた光は、笠部３２の上部に当たって下方へ照射される（図１（Ａ）および（Ｂ）中矢印Ｃ）。 A gap portion 33 is provided between the support portion 31 and the shade portion 32, and a reflection portion 34 that reflects light from the LED bulb 20 toward the gap portion 33 is provided inside the shade portion 32. .
The reflecting portion 34 has a substantially truncated cone shape that is reduced in diameter downward and opened up and down, and the inner surface has a reflecting surface that reflects light.
Thereby, as shown to FIG. 1 (A) and (B), the light emitted downward from the LED light bulb 20 is irradiated below (arrow A in FIG. 1 (A) and (B)). Further, the light emitted from the LED bulb 20 to the side is reflected upward by the reflecting portion 34 and irradiated to the upper ceiling side through the gap portion 33 (in FIGS. 1A and 1B). Arrow B). Furthermore, the light emitted upward from the LED bulb 20 strikes the upper portion of the shade portion 32 and is irradiated downward (arrow C in FIGS. 1A and 1B).

支持部３１と反射部３４との間は、複数（ここでは、３個）の第１連結竿３５により連結されている。すなわち、第１連結竿３５は、支持部３１の外縁部と、反射部３４の内面下端部とを連結する。
また、反射部３４と笠部３２との間は、複数（ここでは、３個）の第２連結竿３６により連結されている。すなわち、第２連結竿３６は、笠部３２の上端部と反射部３４の上端部とを連結する。 The support part 31 and the reflection part 34 are connected by a plurality of (here, three) first connection rods 35. That is, the first connecting rod 35 connects the outer edge portion of the support portion 31 and the inner surface lower end portion of the reflecting portion 34.
Further, the reflecting portion 34 and the shade portion 32 are connected by a plurality (here, three) of second connecting rods 36. That is, the second connecting rod 36 connects the upper end portion of the shade portion 32 and the upper end portion of the reflecting portion 34.

図６（Ａ）に示すように、３本の第１連結竿３５および３本の第２連結竿３６は、各々１２０度間隔で設けられており、平面視で上から見たときに一直線上、かつ、放射状に設けられている。
なお、第１連結竿３５および第２連結竿３６は、各々３本に限るものではなく、４本以上設けることもできる。この場合にも、平面視で上から見たときに一直線上、かつ、放射状に設けられる。例えば、図６（Ｂ）には、第１連結竿３５および第２連結竿３６が、各々９０度間隔で４本設けられている場合を示す。 As shown in FIG. 6 (A), the three first connecting rods 35 and the three second connecting rods 36 are provided at intervals of 120 degrees, and are straight when viewed from above in plan view. And provided radially.
Note that the number of the first connecting rod 35 and the second connecting rod 36 is not limited to three, and four or more may be provided. Also in this case, it is provided in a straight line and radially when viewed from above in a plan view. For example, FIG. 6B shows a case where four first connecting rods 35 and two second connecting rods 36 are provided at intervals of 90 degrees.

なお、支持部３１は、直接ＬＥＤ電球２０のランプ本体２２に当接して支持されることが可能だが、ＬＥＤ電球２０と支持部３１との間に環状部材４０（図２参照）を設けて、環状部材４０を介して支持するようにするのが望ましい。
環状部材４０は、全体円形リング形状をしている。環状部材４０は、断面Ｌ字形状をしており、下側に位置する幅広部４１と、上側に位置する幅狭部４２を有する。幅広部４１の外径は、支持部３１の内径よりも大きく、幅狭部４２の外形は支持部３１の内径よりも小さい。
これにより、環状部材４０の幅狭部４２は支持部３１の内側に挿入され、幅広部４１は支持部３１を下方から支持することになる（図１（Ｂ）参照）。 The support portion 31 can be supported by directly contacting the lamp body 22 of the LED bulb 20, but an annular member 40 (see FIG. 2) is provided between the LED bulb 20 and the support portion 31, It is desirable to support via the annular member 40.
The annular member 40 has an overall circular ring shape. The annular member 40 has an L-shaped cross section, and has a wide portion 41 located on the lower side and a narrow portion 42 located on the upper side. The outer diameter of the wide portion 41 is larger than the inner diameter of the support portion 31, and the outer shape of the narrow portion 42 is smaller than the inner diameter of the support portion 31.
Thereby, the narrow part 42 of the annular member 40 is inserted inside the support part 31, and the wide part 41 supports the support part 31 from below (see FIG. 1B).

また、環状部材４０は、弾性を有する透光性材料で形成するのが望ましい。例えば、透過性のあるシリコンを用いることができる。
これにより、セード３０がランプ本体２２に密着して、ぐらつきが少なくなる。また、環状部材４０の大きさを調整することにより、外径が異なるランプ本体２２を有するＬＥＤ電球２０にも、セード３０の装着が可能になる。 The annular member 40 is preferably formed of a light-transmitting material having elasticity. For example, permeable silicon can be used.
As a result, the shade 30 is in close contact with the lamp body 22 and wobble is reduced. Further, by adjusting the size of the annular member 40, the shade 30 can be attached to the LED bulb 20 having the lamp body 22 having different outer diameters.

従って、セード３０をＬＥＤ電球２０に取り付ける際には、まず、ＬＥＤ電球２０の口金２１側を環状部材４０の下方から挿入し、環状部材４０をＬＥＤ電球２０のランプ本体２２に取り付ける。
次いで、環状部材４０を取り付けたＬＥＤ電球２０を、セード３０の下方から挿入して、環状部材４０の幅狭部４２を支持部３１に挿入して、環状部材４０の幅広部４１によりセード３０の支持部３１を係止する。
そして、セード３０が取り付けられたＬＥＤ電球２０の口金２１を、ソケット１２にねじ込む。 Therefore, when attaching the shade 30 to the LED bulb 20, first, the base 21 side of the LED bulb 20 is inserted from below the annular member 40, and the annular member 40 is attached to the lamp body 22 of the LED bulb 20.
Next, the LED bulb 20 with the annular member 40 attached is inserted from below the shade 30, the narrow portion 42 of the annular member 40 is inserted into the support portion 31, and the wide portion 41 of the annular member 40 causes the shade 30 to The support part 31 is locked.
Then, the base 21 of the LED bulb 20 to which the shade 30 is attached is screwed into the socket 12.

以上、説明した本発明に係る第１実施形態のセード３０によれば、セード３０の支持部３１を、ＬＥＤ電球２０のランプ本体２２により支持する。このため、セード３０を取り付ける部品を別途設ける必要が無く、部品点数を減少させてコストダウンを図ることができる。
このとき、ランプ本体２２が、口金２１側から発光部２３側に向かって拡径するテーパ面を有するので、容易に支持部３１を支持することができる。
また、支持部３１の周囲に笠部３２が設けられているので、笠部３２は、ＬＥＤ電球２０に近づけて取り付けることができ、グレアカットや精度の高い配光制御が可能になる。 As mentioned above, according to the shade 30 of 1st Embodiment which concerns on this invention demonstrated, the support part 31 of the shade 30 is supported by the lamp main body 22 of the LED light bulb 20. As shown in FIG. For this reason, it is not necessary to separately provide a component for attaching the shade 30, and the cost can be reduced by reducing the number of components.
