実施の形態１において、光源１は、発光手段（発光素子）である発光ダイオード（Ｌｉｇｈｔ Ｅｍｉｔｔｉｎｇ Ｄｉｏｄｅ。以下、ＬＥＤ）１０と、ＬＥＤ１０が実装されるＬＥＤ基板１１とを備えている。光源１の構成要素には、ＬＥＤ１０とＬＥＤ基板１１の他、点灯回路（図示せず）と電気的に接続され、駆動電力を点灯回路から光源１に伝達するワイヤーハーネスやコネクタなどの配線部材（図示せず）、及び照明ランプ１００の設計仕様に応じて必要となる電子部品などが含まれる。   In the first embodiment, the light source 1 includes a light emitting diode (Light Emitting Diode, hereinafter referred to as an LED) 10 and a LED substrate 11 on which the LED 10 is mounted. In addition to the LED 10 and the LED substrate 11, the components of the light source 1 are electrically connected to a lighting circuit (not shown), and a wiring member (such as a wire harness or connector) that transmits driving power from the lighting circuit to the light source 1 ( (Not shown) and necessary electronic components according to the design specifications of the illumination lamp 100 are included.

As the resin constituting the globe 2, for example, polycarbonate or acrylic is selected according to product specifications. In the example of FIG. 1, the globe 2 has a curved outer shape. The globe 2 has a function of diffusing, condensing and reflecting light according to the specifications of the illumination lamp 100. These functions are realized directly by the base material itself by forming a diffusion layer (or surface), a lens, a reflective layer (or surface), etc. when molding the glass or resin that is the base material of the globe 2 Alternatively, another member that realizes these functions may be combined on the surface of the base material.

筐体部３は、内部に点灯回路（図示せず）を収納する樹脂筐体３０と、樹脂筐体３０の外側に取り付けられる金属筐体３１とを備える。樹脂筐体３０は、ポリカーボネートやアクリルなどの樹脂素材やセラミックなどを用いて形成される。樹脂筐体３０は、内部に空間を有し、この空間に点灯回路（図示せず）が内包保持されている。金属筐体３１は鉄、アルミニウムなどの金属素材を用いて形成される。   The casing 3 includes a resin casing 30 that houses a lighting circuit (not shown) therein, and a metal casing 31 that is attached to the outside of the resin casing 30. The resin casing 30 is formed using a resin material such as polycarbonate or acrylic, ceramic, or the like. The resin casing 30 has a space inside, and a lighting circuit (not shown) is included and held in this space. The metal casing 31 is formed using a metal material such as iron or aluminum.

グローブ２と筐体部３（の金属筐体３１）とは、任意の接合手段によって接合されている。例えば以下の（１）〜（４）などの方法を用いることができる。

(4) A method in which a locking structure (such as a concave portion and a convex portion, a claw portion and a claw receiving portion) is provided at the opening end portion of the globe 2 and the end portion of the metal housing 31 and joined.

口金部４は、一端が照明装置１５０（例えば、後述の図６を参照）のソケット１６０に嵌合する構造を有しており、照明装置１５０経由で商用電力を照明ランプ１００に入力する入力端である。また、口金部４の他端は、筐体部３に嵌合し、商用電源は口金部４を介して点灯回路（図示せず）に供給される。   The base portion 4 has a structure in which one end is fitted into a socket 160 of a lighting device 150 (see, for example, FIG. 6 described later), and an input end that inputs commercial power to the lighting lamp 100 via the lighting device 150. It is. The other end of the base part 4 is fitted into the casing part 3, and commercial power is supplied to a lighting circuit (not shown) through the base part 4.

図１の例では、金属筐体３１の口金部４とは反対側の端面に光源１が取り付けられており、この光源１の光の出射面を覆うようにして金属筐体３１にグローブ２が取り付けられる。樹脂筐体３０及び金属筐体３１を有する筐体部３とグローブ２とが組み合わさると、これらは全体として電球形照明ランプの外形をなす。また、筐体部３は、一端側において口金部４と接合し、他端側においてグローブ２と接合する。   In the example of FIG. 1, the light source 1 is attached to the end surface of the metal housing 31 opposite to the base 4, and the globe 2 is attached to the metal housing 31 so as to cover the light emission surface of the light source 1. It is attached. When the casing 3 having the resin casing 30 and the metal casing 31 and the globe 2 are combined, they form the outer shape of a light bulb shaped illumination lamp as a whole. Moreover, the housing | casing part 3 is joined to the nozzle | cap | die part 4 in one end side, and is joined to the glove 2 in the other end side.

点灯回路（図示せず）は、商用電力である交流からＬＥＤ１０を駆動する直流に変換するＡＣ−ＤＣコンバータ回路を有する。点灯回路（図示せず）は、口金部４から入力された商用電力を、光源１を点灯させる駆動電力に変換して、駆動電力を光源１に供給する。好ましくは、点灯回路（図示せず）は、ＬＥＤ１０を安定駆動するために、負荷変動の検出機能、負荷変動に応じてＡＣ−ＤＣコンバータ回路から出力される駆動電流を制御する制御機能、商用電力の供給経路を介して流入及び／又は流出するノイズを除去又は低減するフィルタ機能などをさらに有する。   The lighting circuit (not shown) has an AC-DC converter circuit that converts AC power, which is commercial power, into direct current that drives the LED 10. The lighting circuit (not shown) converts the commercial power input from the base unit 4 into driving power for lighting the light source 1 and supplies the driving power to the light source 1. Preferably, the lighting circuit (not shown) includes a load fluctuation detection function, a control function for controlling the drive current output from the AC-DC converter circuit according to the load fluctuation, and commercial power in order to drive the LED 10 stably. And a filter function for removing or reducing noise flowing in and / or out through the supply path.

図２は、図１のグローブと光学要素の構成を説明する図である。以下、図２及び図１を参照して光学要素５について説明する。
光学要素５は、反射部（第１光学要素部）５０と導光部（第２光学要素部）５１とを有している。反射部５０は、その表面に入射した光の略全てを反射する（略全反射の）光学特性を有し、ＬＥＤ基板１１と対向するように配置されている。反射部５０は、板状に構成されており、外周縁部が図１（ｂ）に示すようにグローブ２の外方に突出している。導光部５１は、その表面に入射した光に対して、導光、拡散、反射、透過などの作用をさせる光学特性を有する。これらの光学特性は、照明ランプ１００の製品仕様に基づいて決定される。導光部５１は反射部５０のＬＥＤ基板１１側の面に固定されており、ＬＥＤ側に凸の略円錐台状に形成されている。 FIG. 2 is a diagram illustrating the configuration of the globe and the optical element in FIG. Hereinafter, the optical element 5 will be described with reference to FIGS. 2 and 1.
The optical element 5 includes a reflection part (first optical element part) 50 and a light guide part (second optical element part) 51. The reflection part 50 has an optical characteristic that reflects substantially all of the light incident on the surface thereof (substantially total reflection), and is disposed so as to face the LED substrate 11. The reflection part 50 is comprised by plate shape, and the outer-periphery edge part protrudes outward of the globe 2 as shown in FIG.1 (b). The light guide unit 51 has optical characteristics that cause light incident on the surface thereof to perform actions such as light guide, diffusion, reflection, and transmission. These optical characteristics are determined based on the product specifications of the illumination lamp 100. The light guide unit 51 is fixed to the surface of the reflection unit 50 on the LED substrate 11 side, and is formed in a substantially truncated cone shape that protrudes toward the LED side.

グローブ２及び光学要素５の光学特性は、成形された樹脂材料の表面に加工を施して得ても良く、あるいは、導光、拡散、反射、透過などの作用を得る材料を予め樹脂材料に混合してからグローブ２及び光学要素５として成形しても良い。   The optical characteristics of the globe 2 and the optical element 5 may be obtained by processing the surface of the molded resin material, or a material that obtains an action such as light guide, diffusion, reflection, and transmission is mixed with the resin material in advance. Then, the globe 2 and the optical element 5 may be molded.

光学要素５はグローブ２とともに一体成形された一体成形品である。この点において、光学要素５（及びグローブ２）は樹脂材料を用いることが好ましい。   The optical element 5 is an integrally molded product that is integrally molded with the globe 2. In this respect, it is preferable to use a resin material for the optical element 5 (and the globe 2).

照明ランプ１００の軸に略垂直な光学要素５の反射部５０及び導光部５１はそれぞれ、図１（ｂ）に示すように横断面形状が略円形をなしている。しかし、照明ランプ１００のグローブ２や筐体部３の横断面形状は略円形に限定されない（多角形などでも良い）。   Each of the reflecting portion 50 and the light guide portion 51 of the optical element 5 substantially perpendicular to the axis of the illumination lamp 100 has a substantially circular cross section as shown in FIG. However, the cross-sectional shape of the globe 2 and the casing 3 of the illumination lamp 100 is not limited to a substantially circular shape (a polygon may be used).

光学要素５の最大径は、照明ランプ１００の外郭の最大径Ｒ以下となるように設定する。これは、従来の照明器具へ取り付け可能な寸法条件を満たすことになり、つまり、照明ランプ１００の交換に際して照明器具との干渉を防止する。また、従来、照明ランプと同寸法で個装（箱）仕様の共通化が可能となり、物流コストの面からも好ましい。その他、反射部５０や導光部５１の寸法や外形形状は、照明ランプ１００の製品仕様に基づいて決定される。   The maximum diameter of the optical element 5 is set to be equal to or less than the maximum diameter R of the outline of the illumination lamp 100. This satisfies the dimensional conditions that can be attached to a conventional lighting fixture, that is, when the lighting lamp 100 is replaced, interference with the lighting fixture is prevented. Conventionally, it is possible to share the individual packaging (box) specifications with the same dimensions as the illumination lamp, which is preferable from the viewpoint of distribution cost. In addition, the dimensions and outer shape of the reflection unit 50 and the light guide unit 51 are determined based on the product specifications of the illumination lamp 100.

ところで、ＬＥＤ基板１１を筐体部３（金属筐体３１）の外面に接着剤や接着テープなどの接着部材のみで貼合する場合、熱ストレスや経時劣化などによって捲れや剥がれといった現象が生じることが想定される。この現象を回避するため、ＬＥＤ１０と干渉しないように、導光部５１の反射部５０側の外周端部をＬＥＤ基板１１のＬＥＤ載置面まで延伸させ、延伸した先端部でＬＥＤ基板１１を押圧するようにしてもよい。   By the way, when the LED substrate 11 is bonded to the outer surface of the housing part 3 (metal housing 31) only with an adhesive member such as an adhesive or an adhesive tape, a phenomenon such as dripping or peeling due to thermal stress or deterioration with time may occur. Is assumed. In order to avoid this phenomenon, the outer peripheral end of the light guide unit 51 on the reflective unit 50 side is extended to the LED mounting surface of the LED substrate 11 so as not to interfere with the LED 10, and the LED substrate 11 is pressed by the extended tip. You may make it do.

なお、ＬＥＤ基板１１の中心部や周部に載置するＬＥＤ１０の数やレイアウトは図１に限定されない。   In addition, the number and layout of LED10 mounted in the center part and peripheral part of LED board 11 are not limited to FIG.

図３は、図１の照明ランプの光路の説明図である。
照明ランプ１００においてＬＥＤ１０から放射された光は、反射部５０で反射されてグローブ２の頂部と逆方向に照射、反射部５０で反射されて側方に照射、光学要素５をそのまま通過しグローブ２から外方に照射される。このように光が照射され、照明ランプ１００は、配光角が１８０°を超えて光配向化が達成された全方向タイプの照明ランプとなっている。 FIG. 3 is an explanatory diagram of an optical path of the illumination lamp of FIG.
Light emitted from the LED 10 in the illumination lamp 100 is reflected by the reflecting portion 50 and irradiated in the direction opposite to the top of the globe 2, reflected by the reflecting portion 50 and irradiated to the side, and passes through the optical element 5 as it is. Irradiated from the outside. In this way, the illumination lamp 100 is an omnidirectional illumination lamp in which the light distribution angle exceeds 180 ° and the light orientation is achieved.

以上説明したように実施の形態１によれば、光学要素５がグローブ２と一体的に形成されているため、別々に構成されている場合に比べて構成が単純であり、部品点数の削減及び組立工程の簡素化が可能であり、低コスト化を図ることができる。また、光学要素５の配置構成が単純であるため、照明ランプ１００の小型化（及び軽量化）にも寄与できる。   As described above, according to the first embodiment, since the optical element 5 is formed integrally with the globe 2, the configuration is simple compared to the case where the optical element 5 is configured separately, and the number of parts can be reduced. The assembling process can be simplified and the cost can be reduced. Moreover, since the arrangement configuration of the optical element 5 is simple, it can contribute to the miniaturization (and weight reduction) of the illumination lamp 100.

また、光学要素５がグローブ２と一体的に形成されているため、ＬＥＤ１０のディメンションに左右されることなく光学要素５のディメンション、配置を選択できる。   Further, since the optical element 5 is formed integrally with the globe 2, the dimension and arrangement of the optical element 5 can be selected without being influenced by the dimension of the LED 10.

また、反射部５０の外周縁部がグローブ２の外方に突出しているため、反射部５０からも放熱でき、放熱性を向上することができる。   Moreover, since the outer peripheral edge part of the reflection part 50 protrudes to the outer side of the globe 2, heat can be radiated also from the reflection part 50, and heat dissipation can be improved.

なお、照明ランプ１００は、図１に示した構造に限定されるものではなく、本発明の要旨を逸脱しない範囲で例えば以下のように種々変形実施可能である。この場合も同様の作用効果を得ることができる。   The illumination lamp 100 is not limited to the structure shown in FIG. 1 and can be variously modified as follows without departing from the gist of the present invention. In this case, the same effect can be obtained.

（変形例１）
図４は、図１のグローブと光学要素の構成の変形例１を示す図である。
図４に示すように、グローブ２を、光軸Ｏと直交する方向に分離して第１グローブ（第１外郭部）２１と第２グローブ（第２外郭部）との別体で構成し、照明ランプ１００を構成する際に接合するようにしてもよい。第１グローブ２１と第２グローブ２２とは、同じ光学特性を有することに限定されず、それぞれ別々の光学特性を有するようにしても良い。例えば、第１グローブ２１は、相対的に光の透過率を高く設定し、第２グローブ２２は、相対的に光の透過率を低く設定するなどして、別々の光学特性を有するようにしてもよい。 (Modification 1)
FIG. 4 is a diagram illustrating a first modification of the configuration of the globe and the optical element in FIG. 1.
As shown in FIG. 4, the globe 2 is separated into a direction perpendicular to the optical axis O, and is configured as a separate body of a first globe (first outer portion) 21 and a second globe (second outer portion), When the illumination lamp 100 is configured, it may be joined. The first globe 21 and the second globe 22 are not limited to having the same optical characteristics, and may have separate optical characteristics. For example, the first globe 21 is set to have a relatively high light transmittance, and the second globe 22 is set to have a relatively low light transmittance so that they have different optical characteristics. Also good.

そして、光学要素５は第２グローブ２２と一体的に形成された一体成形品とする。以下では第２グローブ２２と光学要素５とが一体となった一体成形品を第２グローブ体２３という。第１グローブ２１と第２グローブ体２３とは任意の接合手段によって接合される。任意の接合手段としては、例えば以下の（１）〜（４）などの方法を用いることができる。   The optical element 5 is an integrally molded product formed integrally with the second globe 22. Hereinafter, an integrally molded product in which the second globe 22 and the optical element 5 are integrated is referred to as a second globe body 23. The 1st globe 21 and the 2nd globe body 23 are joined by arbitrary joining means. As arbitrary joining means, the following methods (1) to (4) can be used, for example.

（１）接着部材などを用いて、第１グローブ２１の光学要素５側の開孔端部２１ａと、第２グローブ体２３の第１グローブ２１側の端部２３ａとを接着する方法。
