Description

本発明は、発光ダイオード等の発光素子を光源とした照明装置および照明器具に関する。    The present invention relates to a lighting device and a lighting fixture using a light emitting element such as a light emitting diode as a light source.

近年、フィラメント電球に代わって、寿命が長く、また消費電力の少ない半導体発光素子である発光ダイオードを光源とした電球形LEDランプ等の照明装置が各種照明器具の光源として採用されるようになってきている。例えば、特許文献1には、基板に実装された発光ダイオードと、発光ダイオードを点灯させる点灯装置と、点灯装置が収容され、一方側に口金を装着し、他方側に基板を取り付けているカバーと、発光ダイオードを覆うようにカバーの他方側に取付けられた透光性のグローブとを具備しているLED電球が示され、さらに吊り下げ形照明器具やダウンライトの電球用のソケットに、このLED電球が装着されて使用されることが示されている。
特開2008−091140号公報
In recent years, instead of filament light bulbs, lighting devices such as light bulb shaped LED lamps using light emitting diodes, which are semiconductor light emitting elements with long life and low power consumption, have been adopted as light sources for various lighting fixtures. ing. For example, Patent Document 1 discloses a light emitting diode mounted on a substrate, a lighting device that lights the light emitting diode, a cover that houses the lighting device, has a base attached to one side, and a substrate attached to the other side. An LED bulb comprising a translucent glove attached to the other side of the cover to cover the light emitting diode, and the LED in a socket for a hanging luminaire or a downlight bulb It is shown that a light bulb is installed and used.
JP 2008-091140 A

一方、省エネなどのために器具に既に取付けられている白熱電球に替えてLED電球を取付けた場合、既存の器具の反射板等の光学設計は白熱電球の配光に基づいて設計されている。このため、LED電球の配光は白熱電球に近づける必要がある。また、LED電球を構成するためにはLEDからの光をロスなく放射させ、かつ白熱電球の配光に近づける必要がある。   On the other hand, when an LED bulb is attached instead of the incandescent bulb already attached to the fixture for energy saving, the optical design of the reflector and the like of the existing fixture is designed based on the light distribution of the incandescent bulb. For this reason, the light distribution of the LED bulb needs to be close to the incandescent bulb. Moreover, in order to construct an LED bulb, it is necessary to radiate light from the LED without loss and to approximate the light distribution of the incandescent bulb.

しかしながら、LEDは光の指向性が強く輝度が高いため、直視すると眩しさを感じてしまう。このため一般的にはLEDの周囲に遮光壁を設け、水平視方向におけるグレアの発生を極力防止して眩しさを軽減させている。特許文献1においても、カバー部の開口部にLEDを実装した基板が陥入した状態で支持され、LEDの周囲に円筒状の壁が形成されている。このため、LEDから側方(水平)方向に放射される光の多くが円筒状の壁で遮断されるので、その分光出力が低下していた。   However, since the LED has high directivity of light and high luminance, the LED feels dazzling when viewed directly. For this reason, generally, a light shielding wall is provided around the LED to prevent glare in the horizontal viewing direction as much as possible to reduce glare. Also in patent document 1, it supports with the board | substrate which mounted LED in the opening part of the cover part intruded, and the cylindrical wall is formed around LED. For this reason, most of the light radiated from the LED in the lateral (horizontal) direction is blocked by the cylindrical wall, so that the spectral output is reduced.

また、特許文献1におけるLED電球では、口金方向へ光が放射されないので、白熱電球の配光に近づけることができない。このため、特許文献1のLED電球は、既存器具における反射板の光学設計を活かすことは困難であった。   Moreover, in the LED bulb in Patent Document 1, since light is not emitted in the direction of the cap, it cannot be brought close to the light distribution of the incandescent bulb. For this reason, it is difficult for the LED bulb of Patent Document 1 to make use of the optical design of the reflector in the existing instrument.

本発明は、上記課題に鑑みてなされたもので、グレアの発生を防止しつつ、光出力の低下を防止することが可能な照明装置および照明器具を提供しようとするものである。   This invention is made | formed in view of the said subject, and it aims at providing the illuminating device and lighting fixture which can prevent the fall of a light output, preventing generation | occurrence | production of a glare.

A wiring pattern made of copper foil is formed through an electrical insulating layer such as a silicone resin, and the eight LEDs 11 are formed on the wiring pattern so that the remaining seven centering on one of them is substantially concentric. Accordingly, the plurality of LEDs 11 are arranged so as to be substantially symmetrical at the center of the disk-shaped base 12. Each LED 11 is connected in series by a wiring pattern. The

反射体13は、耐候性、耐熱性および電気絶縁性を有する合成樹脂、本実施例では、PBT(ポリブチレンテレフタレート)により円盤状に一体に構成する。円盤の表面側には、表面側に拡開し内面が回転放物面状をなす、同一の形状・寸法を有する凹部13aを複数個、本実施例では8個を、基板12に実装された8個の各LED11に対向するように、その1個の凹部13aを中心として残り7個の凹部13aが略同心円状に略等間隔になるように一体に形成する。上記構成の反射体13の外面および凹部13aの内面にはアルミニウムが蒸着され鏡面加工が施される。   The reflector 13 is integrally formed in a disc shape with a synthetic resin having weather resistance, heat resistance and electrical insulation, in this embodiment, PBT (polybutylene terephthalate). On the surface side of the disk, a plurality of recesses 13a having the same shape and dimensions, with the inner surface being a paraboloid and having an inner surface forming a paraboloidal shape, eight in this embodiment, were mounted on the substrate 12. The remaining seven recesses 13a are integrally formed so as to be substantially concentrically arranged at substantially equal intervals around the one recess 13a so as to face each of the eight LEDs 11. Aluminum is vapor-deposited on the outer surface of the reflector 13 and the inner surface of the recess 13a having the above-described configuration, and is mirror-finished.

凹部13aは、図1(b)に拡大して示すように、個別の8個の反射体を構成するもので、光源であるLED11からの光を、後述の遮光壁14fに照射される量が少なくなるように反射させ、さらに回転対称となる配光を得るためにLED11の発光領域を囲繞するように横断面が円形をなす「すり鉢状」の反射面13bを形成し、凹部13aの開口を光出射部13cとし底部に貫通孔13dを形成する。また、反射体13を構成する円盤の裏面側には、内部に空間部を形成した開口部13eを形成する。   As shown in an enlarged view in FIG. 1B, the recess 13a constitutes eight individual reflectors, and the amount of light from the LED 11 that is a light source is applied to a light shielding wall 14f described later. In order to reflect light so as to reduce the light distribution and to obtain a rotationally symmetric light distribution, a “mortar-shaped” reflective surface 13b having a circular cross section is formed so as to surround the light emitting region of the LED 11, and the opening of the recess 13a is formed. The light emitting portion 13c is formed as a through hole 13d at the bottom. An opening 13e having a space inside is formed on the back side of the disk constituting the reflector 13.

上記に構成された各LED11を実装した基体12を、反射体13の開口部13eに当接し、シリコーン樹脂やエポキシ樹脂等の耐熱性の接着剤で固着して支持する。これにより、反射体13の各凹部13aの底面に形成された貫通孔13dの中心に対して、各LED11が外部に露出して臨むように配置され、各凹部13aにより構成された個別の反射体の光軸y−yとLED11の光軸x−xが略一致した状態に構成される。これにより、平板状の略円板状をなす基体12と円盤状の反射体13が組み合わされて平板状の発光ユニットAが形成される(図1(b))。   The base body 12 on which each LED 11 configured as described above is mounted is in contact with the opening 13e of the reflector 13, and is fixed and supported by a heat-resistant adhesive such as silicone resin or epoxy resin. Thereby, each LED 11 is arranged so as to be exposed and exposed to the center of the through-hole 13d formed in the bottom surface of each concave portion 13a of the reflector 13, and is configured by each concave portion 13a. The optical axis yy of the LED 11 and the optical axis xx of the LED 11 are substantially coincident with each other. Thereby, the flat plate-like light emitting unit A is formed by combining the flat plate-like base 12 and the disk-like reflector 13 (FIG. 1B).

本体14は、熱伝導性の良好な金属、本実施例ではアルミニウムで構成され、横断面が略円形をなす一端部に径の大きな開口部14aを、他端部に径の小さな開口部14bを一体に形成し、外周面が一端から他端に向かい順次直径が小さくなる略円錐状のテーパー面をなすようにして、外観が白熱電球におけるネック部のシルエットに近似させた形状に構成し、外周面に一端から他端に向かい放射状に突出する多数の放熱フィン14cを一体に形成する。これら本体14は、例えば、鋳造、鍛造または切削加工等で加工され、内部に空洞を有して構成される。   The main body 14 is made of a metal having good thermal conductivity, which is aluminum in this embodiment, and has a large-diameter opening 14a at one end having a substantially circular cross section, and a small-diameter opening 14b at the other end. The outer surface is formed into a shape that approximates the silhouette of the neck part of an incandescent light bulb so that the outer peripheral surface forms a substantially conical tapered surface whose diameter gradually decreases from one end to the other. A large number of radiating fins 14c projecting radially from one end to the other end are integrally formed on the surface. These main bodies 14 are processed, for example, by casting, forging, cutting, or the like, and are configured to have a cavity inside.

本体14の一端部の開口部14aには、凹部14dが形成されるように表面を平滑な面に形成した支持段部14eを一体に形成し、この凹部14dに上記構成の発光ユニットAが配置される。すなわち、発光ユニットAにおいて基体12を構成する回路基板の裏面側を、本体21一端部の開口部14aにおける開口端部から挿入し、凹部14dの支持段部14eに熱伝導性を有し電気絶縁性を有するシリコーン樹脂等からなる絶縁シートまたは接着剤等を介して密着させネジ等の固定手段により支持する。   The opening 14a at one end of the main body 14 is integrally formed with a support step 14e having a smooth surface so that the recess 14d is formed, and the light emitting unit A having the above-described configuration is disposed in the recess 14d. Is done. That is, the back side of the circuit board constituting the base 12 in the light emitting unit A is inserted from the opening end of the opening 14a at one end of the main body 21, and the support step 14e of the recess 14d has thermal conductivity and is electrically insulated. It is brought into close contact with an insulating sheet made of a silicone resin or the like having adhesive properties or an adhesive, and is supported by a fixing means such as a screw.

これにより、反射体13を本体14の開口部14aの開口端部から陥入した位置に発光ユニットが配置され、この発光ユニットの周囲と開口端部との間に遮光壁14fが設けられ、反射体13の周囲に、換言すれば、反射体に一体化された各LED11の周囲に、凹部14dの周囲が壁となった遮光壁14fが設けられる。遮光壁14fの高さ寸法h(発光ユニットの最上部から本体14の開口部14aまでの長さ)は、5〜20mm、好ましくは7〜15mmとするのが好ましい。5mm以下だとグレア防止効果が低く、20mmを超えると所望の配光を得るための光学制御が困難となる。これにより、発光ユニットAの光軸a−aが、本体14の中心軸b−bに略合致し(図1(a))、さらに反射体13の光出射部13cが本体14の開口部14aの内側に陥入した状態で配設され、全体として平面視で略円形の発光面を有する光源部Bが構成される。   As a result, the light emitting unit is arranged at a position where the reflector 13 is inserted from the opening end of the opening 14a of the main body 14, and the light shielding wall 14f is provided between the periphery of the light emitting unit and the opening end to reflect the light. Around the body 13, in other words, around each LED 11 integrated with the reflector, a light shielding wall 14f having a wall around the recess 14d is provided. The height dimension h of the light shielding wall 14f (the length from the uppermost part of the light emitting unit to the opening 14a of the main body 14) is 5 to 20 mm, preferably 7 to 15 mm. If it is 5 mm or less, the glare prevention effect is low, and if it exceeds 20 mm, optical control for obtaining a desired light distribution becomes difficult. Thereby, the optical axis aa of the light emitting unit A substantially coincides with the central axis bb of the main body 14 (FIG. 1A), and the light emitting portion 13 c of the reflector 13 is further opened by the opening 14 a of the main body 14. The light source unit B is disposed in a state of being recessed inside and has a substantially circular light emitting surface as a whole in plan view.

上記に構成された本体14の光源部Bには、発光ユニットAの出射光を制御する光制御部材が設けられる。光制御部材は、本実施例では、本体14の遮光壁14fを覆うように、本体14の遮光壁14fの内側周囲に設けられ、発光ユニットAの出射光を反射させる反射部材15で構成する。反射部材15は、本体14の遮光壁14fで遮光されるLED11の直射光または反射体13による反射光を反射させるもので、白熱電球の配光に近くするために、広角の配光が得られる反射板で構成され、その形状は、回転対称となる配光を得るために、遮光壁14fを覆うように横断面が円形で順次その直径が小さくなる「皿状」の反射面15aを有するリング状の枠体で構成する。材質は、光の反射性能を考慮して、耐候性、耐熱性および電気絶縁性を有する合成樹脂、本実施例では、PBTの表面にアルミニウムを蒸着して鏡面加工が施されている。   The light source B of the main body 14 configured as described above is provided with a light control member that controls the emitted light of the light emitting unit A. In this embodiment, the light control member is formed of a reflection member 15 that is provided around the inner side of the light shielding wall 14f of the main body 14 so as to cover the light shielding wall 14f of the main body 14 and reflects the light emitted from the light emitting unit A. The reflecting member 15 reflects the direct light of the LED 11 that is shielded by the light shielding wall 14f of the main body 14 or the reflected light of the reflector 13, and a wide-angle light distribution is obtained in order to approximate the light distribution of the incandescent bulb. A ring having a “dish-like” reflecting surface 15a which is formed of a reflecting plate and has a circular shape in cross section and gradually decreases in diameter so as to cover the light shielding wall 14f in order to obtain a light distribution having a rotationally symmetric shape. It consists of a frame. In consideration of light reflection performance, the material is a synthetic resin having weather resistance, heat resistance, and electrical insulation, and in this embodiment, aluminum is vapor-deposited on the surface of the PBT and mirror-finished.

リング状の枠体の外径寸法は、本体14の凹部14dの遮光壁14fを内側から覆うことができる寸法となし、内径寸法は、個別の反射体13を構成する7個の凹部13aを遮蔽しないように、7個の凹部13aが描く仮想同心円の外周より大きい寸法に形成する。これにより、各LED11から反射体13の凹部13aを介して放射される光の内、本来は本体の遮光壁14fで遮光されて光ロスとなってしまう光を反射面15aで反射させることができる。   The outer diameter of the ring-shaped frame is such that the light-shielding wall 14f of the recess 14d of the main body 14 can be covered from the inside, and the inner diameter is such that the seven recesses 13a constituting the individual reflectors 13 are shielded. In order to avoid this, the size is larger than the outer circumference of the virtual concentric circle drawn by the seven recesses 13a. As a result, among the light radiated from the LEDs 11 through the recess 13a of the reflector 13, the light that is originally shielded by the light shielding wall 14f of the main body and causes light loss can be reflected by the reflecting surface 15a. .

上記に構成された反射部材15の大きい外径寸法を有する開口部には、アクリル樹脂等で構成された透明なカバー部材18が被され、反射体13の貫通孔13dに露出した各LED11が保護され充電部等が覆われる。このカバー部材18と反射部材15は、樹脂成形の際に一体に形成される。すなわちアクリル樹脂からなるカバー部材18の樹脂成形時に、その開口端部にPBTからなる反射部材15の大きい内径寸法を有する開口部が連結されるように樹脂成形によって一体化される。なお、カバー部材18と反射部材15は別体に構成し、個々に組み立てるようにしてもよい。   A transparent cover member 18 made of acrylic resin or the like is covered with the opening having a large outer diameter of the reflection member 15 constituted as described above, and each LED 11 exposed in the through hole 13d of the reflector 13 is protected. And charging parts and the like are covered. The cover member 18 and the reflecting member 15 are integrally formed during resin molding. That is, at the time of resin molding of the cover member 18 made of acrylic resin, the opening end portion of the reflecting member 15 made of PBT is integrated by resin molding so that the opening portion having a large inner diameter is connected. The cover member 18 and the reflection member 15 may be configured separately and assembled individually.

上記に構成された反射部材15およびカバー部材18は、本体14の一端部の開口部14aに嵌め込まれ、反射部材15が反射体13の各凹部13aを囲み、かつ遮光壁14fを覆うように位置されようにして反射体13の光出射部13cに設けられると共に、反射部材15の外周段部が本体開口部14aの開口端部に当接し、当接した部分がシリコーン樹脂やエポキシ樹脂等の耐熱性の接着剤により固着される。   The reflection member 15 and the cover member 18 configured as described above are fitted into the opening 14a at one end of the main body 14, and the reflection member 15 surrounds each recess 13a of the reflector 13 and is positioned so as to cover the light shielding wall 14f. In this way, the light emitting part 13c of the reflector 13 is provided and the outer peripheral step part of the reflecting member 15 contacts the opening end part of the main body opening part 14a, and the contacted part is heat resistant such as silicone resin or epoxy resin. It is fixed with an adhesive.

また、空洞をなす本体14の内部には、点灯装置16を収納し口金部材17を支持するためのケース部材19が嵌め込まれる。ケース部材19は、PBTなどの耐熱性で電気絶縁性を有する合成樹脂で一端部にやや大径の開口部を、他端部に小径の開口部を形成し、本体14の空洞内壁面の形状に略沿った円筒状をなす形状に形成する。また、他端部の小径の開口部はリード線の挿通孔19aを形成した底板19bで一体に閉塞され、外周に段状をなす口金取付部19cを一体に形成する。ケース部材19の内面には、円筒の軸方向に沿ってガイド溝19dが一体に形成され、このガイド溝に点灯装置16を構成する平板状の回路基板16aが縦方向にして嵌合されて支持される。これにより、アルミニウムからなる本体14と回路基板16aとの間の電気的な絶縁がなされる。なお、ガイド溝19dと回路基板16aをシリコーン樹脂やエポキシ樹脂からなる耐熱性の接着剤で固着するようにしてもよい。   A case member 19 for receiving the lighting device 16 and supporting the base member 17 is fitted into the hollow main body 14. The case member 19 is made of a synthetic resin having heat resistance and electrical insulation, such as PBT, and has a slightly large diameter opening at one end and a small diameter opening at the other end. It is formed in a cylindrical shape substantially along the line. Further, the small-diameter opening at the other end is integrally closed by a bottom plate 19b in which a lead wire insertion hole 19a is formed, and a base attaching portion 19c having a step shape is integrally formed on the outer periphery. A guide groove 19d is integrally formed on the inner surface of the case member 19 along the axial direction of the cylinder, and a flat circuit board 16a constituting the lighting device 16 is fitted into the guide groove in the vertical direction and supported. Is done. Thereby, electrical insulation is made between the main body 14 made of aluminum and the circuit board 16a. The guide groove 19d and the circuit board 16a may be fixed with a heat-resistant adhesive made of silicone resin or epoxy resin.

上記のように、内部に回路基板16aを収納したケース部材19は、本体14一端部の開口部14aから挿入され、他端部の開口部14bから口金取付部19cが突出するようにして嵌め込まれ本体14の空洞内に支持される。ケース部材19と本体14の内壁にシリコーン樹脂やエポキシ樹脂等の耐熱性の接着剤を塗布して固着するようにしてもよい。さらに、本体14の他端部の開口部14bから突出した口金取付部19cの外周面に口金部材17を嵌め込み、カシメ若しくはシリコーン樹脂やエポキシ樹脂等の耐熱性を有する接着剤を用いて固着する。これにより、本体14から口金部材17にわたる外周面の外観形状が白熱電球におけるネック部のシルエットに近似させた形状に構成される。点灯装置16の点灯回路は、交流電圧100Vを直流電圧24Vに変換して各LED11に供給するように構成される。なお、回路基板16aの出力端子にはLED給電用の電線が接続され、基体12に実装され直列に配線接続されたLED11に接続される。入力端子には入力線が接続される。   As described above, the case member 19 in which the circuit board 16a is housed is inserted from the opening 14a at one end of the main body 14, and is fitted so that the base mounting portion 19c protrudes from the opening 14b at the other end. It is supported in the cavity of the body 14. A heat-resistant adhesive such as silicone resin or epoxy resin may be applied and fixed to the case member 19 and the inner wall of the main body 14. Further, the base member 17 is fitted into the outer peripheral surface of the base attaching part 19c protruding from the opening part 14b at the other end of the main body 14, and is fixed using caulking or a heat-resistant adhesive such as silicone resin or epoxy resin. Thereby, the external shape of the outer peripheral surface from the main body 14 to the base member 17 is configured to approximate the neck silhouette of the incandescent bulb. The lighting circuit of the lighting device 16 is configured to convert the AC voltage 100V into a DC voltage 24V and supply the converted voltage to each LED 11. In addition, the electric wire for LED electric power feeding is connected to the output terminal of the circuit board 16a, and it connects with LED11 mounted in the base | substrate 12 and wiring-connected in series. An input line is connected to the input terminal.

口金部材17は、エジソンタイプのE26形で、ねじ山を備えた筒状のシェル部17aとこのシェル部の下端の頂部に絶縁部17bを介して設けられたアイレット部17cを備えている。シェル部17aの開口部がケース部材19の口金取付部19cに嵌め込まれ接着やカシメなどにより固着される。これにより、アルミニウムからなる本体21と口金部材17との電気絶縁がなされる。口金部材17のシェル部17aおよびアイレット部17cには、回路基板22aの入力端子から導出された入力線が接続される。   The base member 17 is an Edison type E26 type, and includes a cylindrical shell portion 17a having a thread and an eyelet portion 17c provided on the top of the lower end of the shell portion via an insulating portion 17b. The opening of the shell portion 17a is fitted into the base attachment portion 19c of the case member 19 and is fixed by adhesion or caulking. As a result, the main body 21 made of aluminum and the base member 17 are electrically insulated. An input line derived from an input terminal of the circuit board 22a is connected to the shell portion 17a and the eyelet portion 17c of the base member 17.

次に、上記に構成される電球形の照明装置10の組立手順につき説明する。先ず、点灯装置16を構成する回路基板16aの入力端子に接続された電線を、ケース部材19の底板19bに形成された挿通孔19aから引き出しておく。   Next, an assembly procedure of the light bulb-shaped lighting device 10 configured as described above will be described. First, the electric wire connected to the input terminal of the circuit board 16 a constituting the lighting device 16 is drawn out from the insertion hole 19 a formed in the bottom plate 19 b of the case member 19.

次に、回路基板16aの出力端に接続された電線を発光ユニットAの基体12の入力端子に接続し、さらに発光ユニットAを接続した回路基板16aを縦方向にしてケース部材19に挿入し、さらに回路基板の両端辺をガイド溝19dに嵌合させて支持する。   Next, the electric wire connected to the output end of the circuit board 16a is connected to the input terminal of the base body 12 of the light emitting unit A, and the circuit board 16a to which the light emitting unit A is connected is vertically inserted into the case member 19, Further, both ends of the circuit board are fitted and supported in the guide grooves 19d.

次に、発光ユニットAを接続し回路基板16aを収納したケース部材19を、本体14一端部の開口部14aから挿入し、他端部の開口部14bから口金取付部19cが突出するようにして嵌め込む。   Next, the case member 19 to which the light emitting unit A is connected and the circuit board 16a is accommodated is inserted from the opening 14a at one end of the main body 14 so that the base attaching portion 19c protrudes from the opening 14b at the other end. Fit.

次に、回路基板16aと共に本体14内に挿入された発光ユニットAの回路基板の裏面側を、本体14の凹部14dに形成された支持段部14eに熱伝導性を有し電気絶縁性を有するシリコーン樹脂からなる接着剤を介して密着させ、上面側(表面側)から周囲3箇所程度をねじ等の固定手段を用いて固定する。これにより、基体12の回路基板裏面と支持段部14eの平滑な面が密着して固定され、発光ユニットAを構成する反射体13が本体14の開口部14aの開口端部から陥入させた状態で収容される。   Next, the back side of the circuit board of the light emitting unit A inserted into the main body 14 together with the circuit board 16a is thermally conductive and electrically insulative to the support step 14e formed in the concave portion 14d of the main body 14. The adhesive is made of an adhesive made of silicone resin, and the periphery is fixed at about three locations from the upper surface side (surface side) using a fixing means such as a screw. As a result, the back surface of the circuit board of the base 12 and the smooth surface of the support step portion 14e are fixed in close contact with each other, and the reflector 13 constituting the light emitting unit A is recessed from the opening end portion of the opening portion 14a of the main body 14. Housed in state.

次に、本体14の開口部14a、すなわち、LED11の発光面および反射体13を覆うようにしてカバー部材18を本体14の開口部14aに嵌め込む。これにより、カバー部材18と一体化された反射部材15の外周段部が本体の開口部14aの開口端部に当接し、当接した部分に接着剤を塗布して固着する。これにより反射部材15が、反射体13の各凹部13aを囲みかつ遮光壁14fを覆うように位置して本体14の開口部14aに設けられる。   Next, the cover member 18 is fitted into the opening 14 a of the main body 14 so as to cover the opening 14 a of the main body 14, that is, the light emitting surface of the LED 11 and the reflector 13. Thereby, the outer peripheral step of the reflecting member 15 integrated with the cover member 18 contacts the opening end of the opening 14a of the main body, and the adhesive is applied and fixed to the contacted portion. As a result, the reflecting member 15 is provided in the opening 14a of the main body 14 so as to surround each concave portion 13a of the reflector 13 and cover the light shielding wall 14f.

次に、ケース部材19の挿通孔19aから引き出された電線、すなわち、回路基板16aの入力端子から導出された入力線を、口金17のシェル部17aおよびアイレット部17cに接続し、接続した状態で本体14の開口部14bから突出した口金取付部19cにシェル部17aを嵌め込み接着剤で固着する。   Next, the electric wire drawn out from the insertion hole 19a of the case member 19, that is, the input line led out from the input terminal of the circuit board 16a, is connected to the shell portion 17a and the eyelet portion 17c of the base 17 and is connected. The shell portion 17a is fitted into the base attaching portion 19c protruding from the opening portion 14b of the main body 14 and fixed with an adhesive.

以上により、一端部に略円形の発光面を有する光源部Bが形成され、外観形状が一般白熱電球のネック部のシルエットに近似し、E26形の口金を備え、定格ランプ電力が約5W程度で、白熱電球100Wに相当する明るさの電球形LEDランプとしての照明装置10が構成される。   As described above, the light source part B having a substantially circular light emitting surface is formed at one end, the appearance shape approximates the silhouette of the neck part of a general incandescent bulb, the E26 type cap is provided, and the rated lamp power is about 5 W. The lighting device 10 is configured as a light bulb shaped LED lamp having a brightness equivalent to the incandescent light bulb 100W.

次に、上記のように構成された電球形の照明装置10を光源とした照明器具の構成を説明する。図3に示すように、20は店舗等の天井面Xに埋め込み設置され、E26形の口金を有する白熱電球を光源としたダウンライト式の既存の照明器具で、下面に開口部21aを有する金属製の箱状をなした本体ケース21と、開口部21aに嵌合される金属製の反射体22と、白熱電球のE26形の口金をねじ込むことが可能なソケット23で構成されている。反射体22は、例えばステンレス等の金属板で構成し、反射体22の上面板の中央部にソケット23を設置される。   Next, the structure of the lighting fixture which used the lightbulb-shaped illuminating device 10 comprised as mentioned above as a light source is demonstrated. As shown in FIG. 3, reference numeral 20 denotes an existing downlight type lighting fixture that is embedded in a ceiling surface X of a store or the like and uses an incandescent bulb having an E26-type base as a light source, and has a metal having an opening 21a on the lower surface. The main body case 21 has a box shape made of metal, a metal reflector 22 fitted into the opening 21a, and a socket 23 into which an E26-type cap of an incandescent lamp can be screwed. The reflector 22 is made of, for example, a metal plate such as stainless steel, and a socket 23 is installed at the center of the top plate of the reflector 22.

上記に構成された白熱電球用の既存の照明器具20において、省エネや長寿命化などのために白熱電球に替えて、上述したLED11を光源とする電球形LEDランプとしての照明装置10を使用する。すなわち、電球形の照明装置10は口金部材17をE26形に構成してあるので、上記照明器具の白熱電球用のソケット23にそのまま差し込むことができる。この際、電球形の照明装置10の本体14が略円錐状のテーパー面をなすようにして、外観が白熱電球におけるネック部のシルエットに近似させた形状に構成されているので、ネック部がソケット周辺の反射体22等に当たることなくスムーズに差し込むことができ、電球形の照明装置10における既存照明器具への適用率が向上する。これにより、LEDを光源とした電球形LEDランプとしての照明装置が設置された省エネ形のダウンライトが構成される。   In the existing lighting fixture 20 for incandescent bulbs configured as described above, the lighting device 10 as a bulb-type LED lamp using the LED 11 as a light source is used in place of the incandescent bulb for energy saving and long life. . In other words, since the bulb-shaped lighting device 10 has the base member 17 in the E26 shape, it can be directly inserted into the incandescent bulb socket 23 of the lighting fixture. At this time, the main body 14 of the light bulb-shaped lighting device 10 has a substantially conical tapered surface, and the appearance is configured to approximate the silhouette of the neck portion of the incandescent light bulb. It can be smoothly inserted without hitting the surrounding reflector 22 or the like, and the application rate of the light bulb-shaped lighting device 10 to the existing lighting fixture is improved. Thereby, the energy-saving downlight in which the illuminating device as a light bulb-type LED lamp using LED as a light source is installed is configured.

上記に構成されたダウンライトに電源を投入すると、ソケット23から電球形の照明装置10の口金部材17を介して電源が供給され、点灯装置16が動作し24Vの直流電圧が出力される。この直流電圧は点灯回路の出力端子に接続されたLED給電用の電線を介して直列に接続されたLED11に印加される。これにより、全てのLED11が同時に点灯して白色の光が放射される。  When power is applied to the downlight configured as described above, power is supplied from the socket 23 via the cap member 17 of the light bulb-shaped lighting device 10, the lighting device 16 operates, and a DC voltage of 24V is output. This DC voltage is applied to the LEDs 11 connected in series via an LED power supply wire connected to the output terminal of the lighting circuit. Thereby, all the LEDs 11 are turned on simultaneously, and white light is emitted.

この際、基体12の表面に1個のLED11を中心にし、残り7個の各LED11が略同心円状をなすように略等間隔に実装して配設されているので、各LED11から放射される光は、図4(a)に示すように、反射体13の凹部13aの反射面13bを介して遮光壁14fに照射される量が少なくなるように反射させ、カバー部材15の内面全周囲に向かって略均等に放射される。同時に図中aで示す光、すなわち、LED11の直射光または反射体13による反射光が反射部材15の皿状の反射面15aで反射され、カバー部材15の側方の内面に向かって放射される。   At this time, since one LED 11 is centered on the surface of the base 12 and the remaining seven LEDs 11 are mounted and arranged at substantially equal intervals so as to form a substantially concentric circle, the light is emitted from each LED 11. As shown in FIG. 4A, the light is reflected so that the amount irradiated to the light shielding wall 14f through the reflecting surface 13b of the recess 13a of the reflector 13 is reduced, and is reflected around the entire inner surface of the cover member 15. Radiated almost uniformly toward the camera. At the same time, the light indicated by a in the figure, that is, the direct light of the LED 11 or the light reflected by the reflector 13 is reflected by the dish-like reflecting surface 15a of the reflecting member 15 and radiated toward the inner side surface of the cover member 15. .

反射体13から側方に向かう光aは、本来は本体開口部14aの遮光壁14fで遮光され光ロスとなるが、広角用の反射部材15によりカバー部材15に向かって反射され放射されることによりロスなく活用されると同時に、カバー部材15の側方の光量が増大し、白熱電球の配光に近づいた配光特性をもった照明を行うことができる。特に、光源となる電球形の照明装置10の配光が白熱電球の配光に近づくことで、照明器具20内に配置されたソケット23近傍の反射体22への光の照射量が増大し、白熱電球用として構成された反射体22の光学設計を活かし略設計通りの器具特性を得ることが可能となる。   The light a traveling from the reflector 13 to the side is originally shielded by the light shielding wall 14f of the main body opening 14a and causes light loss, but is reflected and emitted toward the cover member 15 by the wide-angle reflecting member 15. As a result, the amount of light on the side of the cover member 15 increases, and illumination with a light distribution characteristic approaching that of an incandescent bulb can be performed. In particular, when the light distribution of the light bulb-shaped lighting device 10 serving as the light source approaches the light distribution of the incandescent light bulb, the amount of light irradiated to the reflector 22 in the vicinity of the socket 23 disposed in the lighting fixture 20 increases. By utilizing the optical design of the reflector 22 configured for an incandescent lamp, it is possible to obtain appliance characteristics substantially as designed.

また、電球形の照明装置10が点灯されると、各LED11の温度が上昇し熱が発生する。その熱は、アルミニウムからなる基体12から、基体が密着して固着された支持段部14eに伝達されアルミニウムからなる本体14から放熱フィン14cを介して外気に放熱される。この際、基体12および本体14を熱伝導性の良好なアルミニウムで構成したので、LED11で発生する熱を、伝導ロスを少なくして効果的に放熱させることができ、各LED11の温度上昇および温度むらが防止され、発光効率の低下が抑制され、光束低下による照度の低下を防止することができ、同時にLEDの長寿命化を図ることができる。またアルミニウムによって軽量化することができ電球として重くなることがない。   Further, when the light bulb-shaped lighting device 10 is turned on, the temperature of each LED 11 rises and heat is generated. The heat is transmitted from the base body 12 made of aluminum to the support step portion 14e to which the base body is closely attached and fixed, and is radiated from the main body 14 made of aluminum to the outside air through the radiation fins 14c. At this time, since the base body 12 and the main body 14 are made of aluminum having good thermal conductivity, the heat generated in the LEDs 11 can be effectively dissipated with reduced conduction loss. Unevenness is prevented, a decrease in light emission efficiency is suppressed, a decrease in illuminance due to a decrease in luminous flux can be prevented, and at the same time, the life of the LED can be extended. Moreover, it can be reduced in weight by aluminum and does not become heavy as a light bulb.

また、本体14一端部の開口部14aには、凹部14dが形成され、発光ユニットAを構成する反射体13は、本体14の開口部14aから凹部内に陥入させた状態に収容されているので、凹部14dの周囲が壁となった遮光壁14fを有して形成される。これにより、遮光壁の分だけ本体を大きく(長く)構成することができるので本体14の放熱面積を増大させることができ、一層効果的に放熱させることができる。また、点灯装置16の回路部品から発生する熱は、回路基板16aから本体14さらには口金部材17を介して放熱される。これらの放熱作用により点灯装置16の温度上昇および温度むらが抑制され回路部品の信頼性を高めることができる。   A recess 14d is formed in the opening 14a at one end of the main body 14, and the reflector 13 constituting the light emitting unit A is accommodated in a state of being recessed from the opening 14a of the main body 14 into the recess. Therefore, the recess 14d is formed with the light shielding wall 14f around the wall. Thereby, since the main body can be made larger (longer) by the amount of the light shielding wall, the heat radiation area of the main body 14 can be increased, and heat can be radiated more effectively. The heat generated from the circuit components of the lighting device 16 is radiated from the circuit board 16 a through the main body 14 and the base member 17. Due to these heat radiation effects, temperature rise and temperature unevenness of the lighting device 16 are suppressed, and the reliability of the circuit components can be improved.

以上、本実施例によれば、発光ユニットAの反射体13は、本体14の開口部14aの開口端部から陥入した位置に配置し、遮光壁14fに照射される量が少なくなるように反射させるように構成したので、遮光壁14fによって光出力が低下されることが抑制される。また、遮光壁14fは、発光ユニットAの周囲と本体12の開口端部との間に、発光ユニットAの周囲から光放射方向に向かって立設するように設けられており、本体の側方から発光素子が直視されにくくなってグレアが抑制される。さらに、本体14の遮光壁14fの内側周囲に設けられた反射部材15は、遮光壁14fで遮光されるLED11の直射光または反射体13による反射光を反射させるようにしたので、光ロスを少なくし、かつ白熱電球の配光に近づけることが可能となる。これら構成により、グレアを防止しつつ、光出力の低下を抑えて所望の配光に近づけることが可能な照明装置を提供することができる。   As described above, according to the present embodiment, the reflector 13 of the light emitting unit A is disposed at a position recessed from the opening end of the opening 14a of the main body 14 so that the amount of light irradiated to the light shielding wall 14f is reduced. Since it is configured to reflect, the light output is prevented from being lowered by the light shielding wall 14f. The light shielding wall 14f is provided between the periphery of the light emitting unit A and the opening end of the main body 12 so as to stand from the periphery of the light emitting unit A toward the light emission direction. Therefore, the light emitting element is hardly seen directly, and glare is suppressed. Furthermore, since the reflecting member 15 provided around the inner side of the light shielding wall 14f of the main body 14 reflects the direct light of the LED 11 shielded by the light shielding wall 14f or the reflected light by the reflector 13, the light loss is reduced. However, it is possible to approximate the light distribution of an incandescent bulb. With these configurations, it is possible to provide an illuminating device that can prevent a glare and suppress a decrease in light output and bring it closer to a desired light distribution.

また、光源となる電球形の照明装置の配光が白熱電球の配光に近づくことで、既存の照明器具20の白熱電球に替えて使用しても白熱電球の配光により近づいた配光特性を有する省エネ形の照明器具を提供することができる。また、電球形の照明装置の外観を白熱電球におけるネック部のシルエットに近似させた形状に構成したので、白熱電球に替えて装着する場合でも、ソケットにスムーズに差し込むことができ、電球形LEDランプとしての照明装置における既存照明器具への適用率を向上させることができる。   Moreover, even if it uses it instead of the incandescent lamp of the existing lighting fixture 20, the light distribution characteristic which approached the light distribution of the incandescent lamp because the light distribution of the light bulb-shaped lighting device as the light source approaches the light distribution of the incandescent lamp. An energy-saving lighting fixture having In addition, because the appearance of the light bulb-shaped lighting device is configured to approximate the silhouette of the neck portion of an incandescent light bulb, it can be smoothly inserted into the socket even when it is installed instead of an incandescent light bulb. As a result, it is possible to improve the rate of application to existing lighting fixtures.

また、発光ユニットAの反射体13は、本体14の開口部14aの開口端部から陥入した位置に配置され、反射部材15は遮光壁14fを覆うようにして設けられるので、遮光壁14fによる本体の放熱面積増大によるに放熱効果と相まって、反射部材15による光制御によって白熱電球の配光に近づけることができる。   Further, the reflector 13 of the light emitting unit A is disposed at a position recessed from the opening end of the opening 14a of the main body 14, and the reflecting member 15 is provided so as to cover the light shielding wall 14f. Combined with the heat radiation effect due to the increase in the heat radiation area of the main body, the light distribution by the reflecting member 15 can be close to the light distribution of the incandescent bulb.

また、本体開口部14aの光源部Bは、凹部14dを構成するために暗くなる遮光壁14fがアルミニウムを蒸着した綺麗な反射部材15によって覆われ、同じくアルミニウムを蒸着した反射体13の凹部13aと組み合わされて綺麗に光る「すり鉢状」の反射鏡をなすように構成され、外観・意匠的にも優れた電球形の照明装置を提供することができる。   The light source part B of the main body opening 14a has a light shielding wall 14f that is darkened to form the concave part 14d covered with a beautiful reflecting member 15 vapor-deposited with aluminum, and the concave part 13a of the reflector 13 with vapor-deposited aluminum. It is possible to provide a light bulb-shaped lighting device that is configured to form a “mortar-shaped” reflecting mirror that shines beautifully when combined, and is excellent in appearance and design.

カバー部材18と反射部材15は樹脂成形の際に一体に形成したので、カバー部材18を単に本体14の開口端14aに嵌め込むだけで、反射部材15も同時に組み立てることができるので作業が簡素化されてコスト的にも有利となる。同時に、反射部材15を、遮光壁14fを覆う所定の位置に自動的に確実に配置させることができ、位置ズレ等よって反射性能が損なわれることがなく、安定した光学特性を発揮することができる。   Since the cover member 18 and the reflection member 15 are integrally formed at the time of resin molding, the reflection member 15 can be assembled at the same time simply by fitting the cover member 18 into the opening end 14a of the main body 14, thereby simplifying the operation. This is advantageous in terms of cost. At the same time, the reflecting member 15 can be automatically and reliably disposed at a predetermined position covering the light shielding wall 14f, and the reflecting performance is not impaired by a positional shift or the like, and stable optical characteristics can be exhibited. .

以上、本実施例において、電球形の照明装置の本体14は、外方に露出する外面部分を、例えば、凹凸若しくは梨地状に形成して表面積を大きくしたり、白色塗装や白色アルマイト処理を施して外面部分の熱放射率を高めるようにしてもよい。また、白色塗装や白色アルマイト処理を施した場合には、電球形の照明装置を照明器具に装着して点灯した場合、外面に露出するアルミニウム製の本体14外面の反射率が高くなり、器具効率を高めることが可能となり、また外観・意匠的にも良好となり商品性を高めることもできる。   As described above, in the present embodiment, the main body 14 of the light bulb-shaped lighting device has an outer surface portion that is exposed to the outside, for example, an uneven surface or a satin surface shape to increase the surface area, or white coating or white alumite treatment. Thus, the thermal emissivity of the outer surface portion may be increased. Also, when white paint or white alumite treatment is applied, when the light bulb-shaped lighting device is mounted on a lighting fixture and lit, the reflectance of the outer surface of the aluminum main body 14 exposed to the outer surface is increased, and the appliance efficiency is increased. In addition, the appearance and design are improved, and the product quality can be improved.

点灯装置16の回路基板16aを、ケース部材19の内部に縦方向に配設したが、回路基板をより小型に構成して、横方向(水平方向)や斜めに傾斜させて配設してもよい。また、口金部材17をE26形に構成したが、他の例えば、E17形等でもよく、さらにエジソンタイプ以外の口金で構成してもよい。   Although the circuit board 16a of the lighting device 16 is disposed in the longitudinal direction inside the case member 19, the circuit board may be configured to be smaller and disposed in a lateral direction (horizontal direction) or obliquely. Good. Moreover, although the base member 17 is configured in the E26 type, other types such as E17 type may be used, and a base other than the Edison type may be used.

本実施例は、光制御部材を、透光性を有するカバー部材の少なくとも周縁部に形成された光拡散手段で構成したものである。以下、図5、図6および図4(b)に従って説明する。なお、図5、図6および図4(b)には実施例1の図1〜図4と同一部分には同一の符号を付し、詳細な説明は省略する。  In this embodiment, the light control member is composed of light diffusing means formed on at least the peripheral edge of a light-transmitting cover member. Hereinafter, description will be made with reference to FIGS. 5, 6, and 4 (b). 5, 6, and 4 (b), the same parts as those in FIGS. 1 to 4 of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

本実施例では、カバー部材として、本体14の開口部14aを覆うグローブで構成する。グローブ30は、透光性を有し、例えば、厚さが薄いポリカーボネイト等の合成樹脂などの材質で、全体形状が白熱電球のボール部分のシルエットに近似させた滑らかな曲面状に形成する。さらに曲面状に構成された中央部を透明に形成し、周縁部を乳白色として光拡散手段40を形成する。   In this embodiment, the cover member is a glove that covers the opening 14a of the main body 14. The globe 30 is translucent, and is made of, for example, a synthetic resin such as polycarbonate having a small thickness, and is formed into a smooth curved surface whose overall shape approximates the silhouette of the ball portion of the incandescent bulb. Further, the light diffusion means 40 is formed with a transparent central portion formed in a curved shape and a milky white periphery.

さらに開口側の直径を小さくするようにすぼめて筒状をなす開口30aを一体に形成すると共に、すぼめた筒状の開口30aの周囲に段部30bを形成する。また、本体14の複数の放熱フィン14cは、図6に示すように、本体開口部14aの開口端部まで延長して形成し、各フィン間に形成される隙間sの端部(開口部側の端部)は、光を取り込めるように開放させて形成する。   Further, the opening 30a having a tubular shape is integrally formed by reducing the diameter on the opening side, and a step portion 30b is formed around the recessed cylindrical opening 30a. Further, as shown in FIG. 6, the plurality of heat radiating fins 14c of the main body 14 are formed to extend to the opening end portions of the main body opening portions 14a, and the end portions (opening side) of the gaps s formed between the fins. The end of the light source is formed to be open so that light can be taken in.

上記構成のグローブ30は、実施例1と同様に本体14の凹部14dに嵌め込まれ、グローブの筒状をなす開口30aと本体の凹部14d内周面との当接部分をシリコーン樹脂やエポキシ樹脂等の耐熱性の接着剤で固着する。これにより、グローブ30の開口30a周囲に形成された段部30bが、複数の放熱フィン14c間に形成された各隙間sの上面に位置する。換言すれば、上端が開放されたフィンの隙間sがグローブ周縁部の乳白色部分である光拡散手段40に対向して位置される。   The glove 30 having the above-described configuration is fitted into the concave portion 14d of the main body 14 in the same manner as in the first embodiment, and a contact portion between the cylindrical opening 30a of the glove and the inner peripheral surface of the concave portion 14d of the main body is silicone resin, epoxy resin, or the like. Fix with heat resistant adhesive. Thereby, the step part 30b formed in the circumference | surroundings of the opening 30a of the globe 30 is located in the upper surface of each clearance gap s formed between the several radiation fin 14c. In other words, the gap s between the fins whose upper ends are open is positioned to face the light diffusing means 40 that is the milky white part of the glove periphery.

また、本実施例における本体14は、アルミニウム等の熱伝導性の良好な金属からなる本体ケース14gとカバー14hで構成する。本体ケース14gは、凹部14dの底面に平滑な面からなる支持部14e´を一体に形成し、外周面に一端から他端に向かい放射状に突出する多数の放熱フィン14cを一体に形成する。カバー14hは、白色のPBT等、耐熱性で電気絶縁性を有する合成樹脂で一端部にやや大径の開口部を、他端部に小径の開口部を形成し、その直径が段状をなして減少する円筒状をなすように形成して、外観が白熱電球におけるネック部のシルエットに近い形状に構成する。   Further, the main body 14 in the present embodiment is constituted by a main body case 14g and a cover 14h made of a metal having good thermal conductivity such as aluminum. The main body case 14g is integrally formed with a smooth support portion 14e 'on the bottom surface of the recess 14d, and integrally formed with a large number of radiating fins 14c projecting radially from one end to the other end on the outer peripheral surface. The cover 14h is a heat-resistant and electrically insulating synthetic resin such as white PBT, and has a slightly large diameter opening at one end and a small diameter opening at the other end, and the diameter is stepped. It is formed so as to form a cylindrical shape that decreases, and the appearance is configured to be close to the silhouette of the neck portion of the incandescent bulb.

上記に構成された電球形の照明装置10を点灯すると、図4(b)に示すように、各LED11から放射される光が反射体13の凹部13aを介して遮光壁14fに照射される量が少なくなるように反射させ、グローブ30の内面全周囲に向かって略均等に放射されて透明な部分から光が放射され、同時にLED11の直射光または反射体13による反射光がグローブ30周縁部の内面にも放射される。これらの光bは周縁部に形成された光拡散手段40、すなわち、乳白色の部分を透過する際に光が拡散され、各放熱フィン14cの上端が開放された隙間sを通過して口金方向、すなわち、照明装置を器具へ装着した時の上部方向へも光が拡散されて放射される。これにより、本実施例の電球形LEDランプとしての照明装置10によれば、後方、すなわち、口金側にも光を放射さることができ白熱電球の配光に、より近づけることができる。なお、グローブ30の周縁部のみを乳白色に形成して光拡散手段40を構成したが、グローブ全体を乳白色に形成することにより周縁部に光拡散手段を構成するようにしてもよい。   When the light bulb-shaped lighting device 10 configured as described above is turned on, the amount of light emitted from each LED 11 is applied to the light shielding wall 14f through the concave portion 13a of the reflector 13 as shown in FIG. Is reflected almost uniformly toward the entire inner surface of the globe 30, and light is emitted from the transparent portion. At the same time, direct light from the LED 11 or light reflected by the reflector 13 is reflected on the periphery of the globe 30. Also radiated to the inner surface. The light b is diffused when passing through the light diffusing means 40 formed at the peripheral portion, that is, the milky white portion, and passes through the gap s in which the upper ends of the radiating fins 14c are opened. That is, light is diffused and emitted also in the upper direction when the lighting device is mounted on the fixture. Thereby, according to the illuminating device 10 as a lightbulb-shaped LED lamp of a present Example, light can be radiated back, ie, the nozzle | cap | die side, and it can be brought closer to the light distribution of an incandescent lamp. Although the light diffusing unit 40 is configured by forming only the peripheral part of the globe 30 in milky white, the light diffusing unit may be configured in the peripheral part by forming the entire globe in milky white.

また、本実施例によれば、本体14の複数の放熱フィン14cは、本体開口部14aの開口端部まで延長して形成し、各フィン間に形成される隙間sの端部は、光を取り込めるように開放させて形成したので、グローブ周縁部の光拡散手段40で拡散された光bが放熱フィン14cによって遮られることなく、後方、すなわち、口金側に効果的に光を放射さることができ、白熱電球の配光に、より一層近づけることができる。   Further, according to the present embodiment, the plurality of radiating fins 14c of the main body 14 are formed to extend to the opening end of the main body opening 14a, and the end of the gap s formed between the fins emits light. Since it is formed so that it can be taken in, the light b diffused by the light diffusing means 40 at the periphery of the globe can be effectively radiated to the rear side, that is, the base side without being blocked by the heat radiating fins 14c. It can be made closer to the light distribution of incandescent bulbs.

また、本体ケース14gは、凹部14dの底面に平滑な面からなる支持部14e´を一体に形成し、発光ユニットA、すなわち、基体12を密着させて支持するようにしたので、各LED11から発生する熱を、伝導ロスをより少なくして効果的に放熱させることができる。その他、本実施例における他の構成、作動、作用効果、変形例等は、実施例1と同様である。   Further, the main body case 14g is integrally formed with a support portion 14e 'formed of a smooth surface on the bottom surface of the recess 14d so as to support the light emitting unit A, that is, the base 12 in close contact with each other. It is possible to dissipate heat effectively with less conduction loss. Other configurations, operations, operational effects, modifications, and the like in this embodiment are the same as those in the first embodiment.

本実施例は、光制御部材を実施例1の反射部材15と実施例2の光拡散手段40を組み合わせて構成したものである。以下、図7および図4(c)に従って説明する。なお、図7および図4(c)には実施例1の図1〜図4および実施例2の図5、図6および図4(b)と同一部分には同一の符号を付し、詳細な説明は省略する。  In this embodiment, the light control member is configured by combining the reflecting member 15 of the first embodiment and the light diffusion means 40 of the second embodiment. Hereinafter, a description will be given with reference to FIGS. 7 and 4C. 7 and 4 (c), the same parts as those in FIGS. 1 to 4 of the first embodiment and FIGS. 5, 6 and 4 (b) of the second embodiment are denoted by the same reference numerals, and the details are as follows. Detailed explanation is omitted.

本実施例では、実施例2の周縁部に光拡散手段40を設けたグローブ30において、筒状をなす開口30aを傾斜させてその内側の表面にアルミニウムを蒸着し反射面15aとなした反射部材15を一体若しくは別体に形成する。これによれば、図4(c)に示すように、反射部材15による光aによって側方の光量が増大し、さらにグローブ周縁部の光拡散手段40による光bによって、後方、すなわち、口金側にも光を放射させることができ、より一層白熱電球の配光に近づけることができる。   In the present embodiment, in the globe 30 provided with the light diffusing means 40 at the peripheral edge of the second embodiment, the reflecting member 15a is formed by inclining the cylindrical opening 30a and depositing aluminum on the inner surface thereof to form the reflecting surface 15a. 15 is formed integrally or separately. According to this, as shown in FIG. 4 (c), the amount of light on the side is increased by the light a by the reflecting member 15, and the rear side, that is, the base side by the light b by the light diffusing means 40 at the periphery of the globe. Can also emit light, making it even closer to the light distribution of an incandescent bulb.
