Description

本発明は、LEDランプおよび照明器具に関し、特に、直管蛍光灯の代替品として好適な直管蛍光灯型のLEDランプに関する。   The present invention relates to an LED lamp and a lighting fixture, and more particularly to a straight tube fluorescent lamp type LED lamp suitable as a substitute for a straight tube fluorescent lamp.

寿命による交換頻度を低減すると共に省電力化を図るため、蛍光灯よりも長寿命かつ省電力であるLEDランプが蛍光灯の代替品として提案されている。
例えば、直管蛍光灯の代替品となる直管蛍光灯型のLEDランプの場合、蛍光灯に応じた長さを有する長尺状の基板と、当該基板上に長手方向に沿って実装された複数個のLEDとを備えた構成を有する。そして、基板のLEDとは反対側には外殻の一部を構成するアルミニウム製のヒートシンクが取り付けられ、そのヒートシンクによる放熱効果によって、LEDの温度上昇を抑えてLEDの発光効率の低下を防止している。また、LEDランプにはAC/DCコンバータを含む点灯回路が内蔵されており、照明器具から入力される交流電圧を前記点灯回路によって直流電圧に変換しLEDに供給し点灯させている。
In order to reduce the replacement frequency due to the lifetime and to save power, an LED lamp having a longer lifetime and power saving than the fluorescent lamp has been proposed as an alternative to the fluorescent lamp.
For example, in the case of a straight tube fluorescent lamp type LED lamp that is a substitute for a straight tube fluorescent lamp, a long substrate having a length corresponding to the fluorescent lamp, and mounted on the substrate along the longitudinal direction It has the structure provided with several LED. An aluminum heat sink that constitutes a part of the outer shell is attached to the side of the substrate opposite to the LED, and the heat dissipation effect of the heat sink suppresses the LED temperature rise and prevents the LED luminous efficiency from decreasing. ing. Further, the LED lamp has a built-in lighting circuit including an AC / DC converter, and an AC voltage input from the lighting fixture is converted into a DC voltage by the lighting circuit and supplied to the LED for lighting.

このような交流点灯型のLEDランプは、LEDランプに点灯回路が内蔵されているためLEDで生じる熱によって点灯回路の寿命が縮まり易く、そのためLEDランプ自体の寿命も縮まり易い。また、点灯回路で生じる熱によってLEDの温度が上昇しLEDの発光効率が低下するおそれもある。さらに、点灯回路の内蔵はLEDランプの大型化や高価格化の原因にもなる。そこで、AC/DCコンバータを含む点灯回路をランプ外部の例えば照明器具等に設ける等して、LEDランプの口金には直流電圧が供給される構成とし、この構成で点灯させる直流点灯型のLEDランプの開発が進められている。   In such an AC lighting type LED lamp, since the lighting circuit is built in the LED lamp, the life of the lighting circuit is likely to be shortened by heat generated in the LED, and therefore the life of the LED lamp itself is also likely to be shortened. Further, the heat generated in the lighting circuit may increase the temperature of the LED and reduce the light emission efficiency of the LED. Furthermore, the built-in lighting circuit causes the LED lamp to become larger and more expensive. In view of this, a lighting circuit including an AC / DC converter is provided outside the lamp, for example, in a lighting fixture or the like, so that a DC voltage is supplied to the base of the LED lamp. Development is underway.

ところで、ヒートシンクは、アルミニウム製であるため導電性を有するが、LEDランプを照明器具に取り付けられた状態において接地されていない。そのため、LEDモジュールや照明器具からにヒートシンクに電流が漏れた場合に、ヒートシンクに触れると感電のおそれがある。特に、直流点灯型のLEDランプの場合、ヒートシンクの対地電圧が、電源電圧とランプ電圧との単純な総和となり、交流点灯型のLEDランプの場合の対地電圧の実効値よりも大きくなるため、感電のおそれが大きい。   By the way, since the heat sink is made of aluminum and has conductivity, it is not grounded in a state where the LED lamp is attached to the lighting fixture. Therefore, when current leaks from the LED module or the lighting fixture to the heat sink, touching the heat sink may cause an electric shock. In particular, in the case of a DC lighting type LED lamp, the ground voltage of the heat sink is a simple sum of the power supply voltage and the lamp voltage, which is larger than the effective value of the ground voltage in the case of an AC lighting type LED lamp. There is a great risk of

本発明は、上記の課題に鑑み、感電のおそれが小さい直流点灯型のLEDランプおよび照明器具を提供することを目的とする。   In view of the above problems, an object of the present invention is to provide a DC lighting type LED lamp and a lighting fixture that are less likely to cause an electric shock.

上記目的を達成するために、本発明に係るLEDランプは、口金ソケットおよびアース端子受け治具を備えた照明器具に取り付けられ直流点灯されるLEDランプであって、長尺状の基板にその長手方向に沿って複数のLEDが実装されたLEDモジュールと、前記LEDモジュールが内部に収容され、少なくとも一部が導電性部材で構成された長尺状の外殻と、当該外殻の長手方向一端側に配置され、前記口金ソケットに装着される口金と、前記外殻の長手方向他端側に配置され、前記導電性部材と電気的に接続されたアース端子を有し、前記アース端子受け治具に装着されるアース部材と、を備えることを特徴とする。   In order to achieve the above object, an LED lamp according to the present invention is an LED lamp that is attached to a lighting fixture having a base socket and a ground terminal receiving jig and is lit by direct current, and is formed on a long substrate. An LED module in which a plurality of LEDs are mounted along a direction, a long outer shell in which the LED module is housed and at least a part of which is made of a conductive member, and one longitudinal end of the outer shell A grounding terminal disposed on the other end side in the longitudinal direction of the outer shell and electrically connected to the conductive member; And a grounding member to be mounted on the tool.

また、本発明に係る照明器具は、上記LEDランプが取り付けられる照明器具であって、前記口金が装着される口金ソケットと、前記アース部材が装着されるアース端子受け治具とを備えることを特徴とする。   Further, a lighting fixture according to the present invention is a lighting fixture to which the LED lamp is attached, and includes a base socket to which the base is mounted and a ground terminal receiving jig to which the ground member is mounted. And

本発明に係るLEDランプおよび照明器具は、LEDランプの外殻の少なくとも一部を構成する導電性部材と電気的に接続されたアース端子を有するアース部材が、照明器具のアース端子受け治具に装着されるため、導電性部材に電流が漏れたとしても感電のおそれが小さい。   In the LED lamp and the lighting fixture according to the present invention, a ground member having a ground terminal electrically connected to a conductive member constituting at least a part of the outer shell of the LED lamp is used as a ground terminal receiving jig of the lighting fixture. Since it is mounted, there is little risk of electric shock even if current leaks into the conductive member.

[Embodiment]
1 is a partially broken plan view showing an LED lamp according to the present embodiment, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 3 is a cross-sectional view taken along line BB in FIG. It is a figure and is CC sectional view taken on the line in FIG. 4, FIG.

図1および図2に示すように、本実施の形態に係るLEDランプ100は、直管蛍光灯の代替品となる直管蛍光灯型のLEDランプであって、LEDモジュール110、ヒートシンク120、カバー130、口金140およびアース部材150を備える。なお、ヒートシンク120とカバー130とでLEDモジュール110の外殻101が構成されている。   As shown in FIGS. 1 and 2, an LED lamp 100 according to the present embodiment is a straight tube fluorescent lamp type LED lamp that is a substitute for a straight tube fluorescent lamp, and includes an LED module 110, a heat sink 120, a cover. 130, a base 140, and a ground member 150. The heat sink 120 and the cover 130 constitute an outer shell 101 of the LED module 110.

LEDモジュール110は、長尺直線状の基板111を有し、当該基板111の実装面112には、基板111の長手方向に沿って複数個のLED113が例えば一列に直線状に実装されていると共に、温度ヒューズ114および電流ヒューズ115がそれぞれ1つずつ実装されている。複数のLED113、温度ヒューズ114および電流ヒューズ115は、基板111の実装面112に形成された配線パターン116によって電気的に、例えば直列接続されている。例えば、LED113の電圧は1つが3.3Vであって、それが30個実装され直列接続されることによりLEDランプ100全体としてのランプ電圧は3.3V×30=99Vとなる。   The LED module 110 has a long linear substrate 111, and a plurality of LEDs 113 are mounted on the mounting surface 112 of the substrate 111 along the longitudinal direction of the substrate 111, for example, in a straight line. One thermal fuse 114 and one current fuse 115 are mounted. The plurality of LEDs 113, temperature fuses 114, and current fuses 115 are electrically connected, for example, in series by a wiring pattern 116 formed on the mounting surface 112 of the substrate 111. For example, one LED 113 has a voltage of 3.3V, and when 30 LEDs are mounted and connected in series, the lamp voltage of the LED lamp 100 as a whole becomes 3.3V × 30 = 99V.

基板111は、例えば、金属ベースプリント配線板、ガラスコンポジット基板、ガラスエポキシ基板等とすることが考えられる。LED113で生じる熱をヒートシンク120へ効率良く伝導させるためには、基板111の熱伝導性が高いことが好ましい。   The substrate 111 may be, for example, a metal base printed wiring board, a glass composite substrate, a glass epoxy substrate, or the like. In order to efficiently conduct the heat generated in the LED 113 to the heat sink 120, it is preferable that the substrate 111 has high thermal conductivity.

LED113は、例えば表面実装(SMD)型の白色LEDである。なお、LED113は、表面実装型のものに限らず、例えば、基板111にLEDチップをフリップチップ実装またはワイヤーボンディング実装し、前記LEDチップを蛍光体分散樹脂で封止した構成であっても良い。この場合、例えば、LEDチップを青色発光するものとし、蛍光体分散樹脂の樹脂をシリコーン樹脂とし、蛍光体を黄緑色蛍光体(例えば(Ba,Sr)2SiO4:Eu2+やY3(Al,Ga)512:Ce3+)と赤色蛍光体(Sr2Si58:Eu2+や(Ca,Sr)S:Eu2+や(Ba,Sr,Ca)AlSiN3:Eu2+)との混合物とすることが考えられる。 The LED 113 is, for example, a surface mount (SMD) type white LED. Note that the LED 113 is not limited to a surface-mount type, and for example, an LED chip may be flip-chip mounted or wire-bonded mounted on the substrate 111, and the LED chip may be sealed with a phosphor-dispersed resin. In this case, for example, the LED chip emits blue light, the phosphor-dispersed resin is a silicone resin, and the phosphor is a yellow-green phosphor (for example, (Ba, Sr) 2 SiO 4 : Eu 2+ or Y 3 ( al, Ga) 5 O 12: Ce 3+) and red phosphor (Sr 2 Si 5 N 8: Eu 2+ and (Ca, Sr) S: Eu 2+ and (Ba, Sr, Ca) AlSiN 3: Eu 2 + )).

ヒートシンク120は、例えば、長尺直線状のアルミニウム製であって、基板111の背面117(実装面112とは反対側の面)に、基板111と長手方向を揃えて配置されており、例えば接着やねじ止め等で基板111に固定されている。ヒートシンク120とLEDモジュール110とは熱的に接触しており、LED113で生じた熱は、基板111を介してヒートシンク120に伝導し、ヒートシンク120から放射により放熱される。ヒートシンク120と基板111とを面接触させることによって、高い放熱効果を得ることができる。   The heat sink 120 is made of, for example, long linear aluminum, and is arranged on the back surface 117 (the surface opposite to the mounting surface 112) of the substrate 111 so as to be aligned with the substrate 111 in the longitudinal direction. It is fixed to the substrate 111 by screwing or the like. The heat sink 120 and the LED module 110 are in thermal contact, and heat generated by the LED 113 is conducted to the heat sink 120 via the substrate 111 and is radiated from the heat sink 120 by radiation. By bringing the heat sink 120 and the substrate 111 into surface contact, a high heat dissipation effect can be obtained.

なお、ヒートシンク120は、アルミニウム製のものに限定されないが、熱伝導性が良くかつ軽量であることが好ましい。また、ヒートシンク120は、どのような形状であっても良いが、LEDモジュール110からの出射光を遮らない形状であることが好ましい。   The heat sink 120 is not limited to an aluminum one, but preferably has good thermal conductivity and is lightweight. The heat sink 120 may have any shape, but preferably has a shape that does not block the light emitted from the LED module 110.

図3および図4に示すように、カバー130は、例えば、横断面形状が略円弧形の長尺状であって、ヒートシンク120と長手方向を揃えて配置されており、一対の側端部(短手方向端部)131,132を、ヒートシンク120の側面121,122に設けられた溝123,124に嵌め込むことによって、LEDモジュール110を覆った状態でヒートシンク120に取り付けられている。   As shown in FIG. 3 and FIG. 4, the cover 130 is, for example, an elongated shape having a substantially arc-shaped cross section, and is arranged with the heat sink 120 aligned in the longitudinal direction, and has a pair of side end portions. By fitting the (short-side end portions) 131 and 132 into grooves 123 and 124 provided on the side surfaces 121 and 122 of the heat sink 120, the LED module 110 is attached to the heat sink 120.

カバー130は、例えば、ポリカーボネート等の樹脂やガラス等の透光性材料で形成されている。なお、ガラスは、熱伝導率が高く(ポリカーボネートの5倍程度)、LEDの温度上昇を抑制するための放熱効果が高いため、カバー130の材料として好適である。   The cover 130 is made of, for example, a resin such as polycarbonate or a light transmissive material such as glass. Note that glass is suitable as a material for the cover 130 because it has high thermal conductivity (about five times that of polycarbonate) and has a high heat dissipation effect for suppressing the temperature rise of the LED.

図2に戻って、口金140は、キャップ状をした本体141および一対の口金ピン142,143を有し、外殻101の長手方向一端側に配置されている。本体141は、例えば、シリコン樹脂等の耐熱性の合成樹脂からなる。一対の口金ピン142,143は、例えばアルミニウムや銅等の金属からなり、本体141に設けられた貫通孔144,145を貫通するようにそれぞれ圧入により本体141に植設されており、LEDモジュール110の配線パターン116とリード線146,147を介して電気的に接続されている。   Returning to FIG. 2, the base 140 has a cap-shaped main body 141 and a pair of base pins 142 and 143, and is arranged on one end side in the longitudinal direction of the outer shell 101. The main body 141 is made of, for example, a heat-resistant synthetic resin such as silicon resin. The pair of cap pins 142 and 143 are made of metal such as aluminum or copper, for example, and are implanted in the main body 141 by press fitting so as to penetrate through holes 144 and 145 provided in the main body 141. The wiring pattern 116 and the lead wires 146 and 147 are electrically connected.

アース部材150は、キャップ状をした本体151、一対のアース端子152,153および導電部材154を有し、外殻101の長手方向他端側に配置されている。本体151は、例えば、シリコン樹脂等の耐熱性の合成樹脂からなる。一対のアース端子152,153は、例えば、アルミニウムや銅等の金属からなり、本体151の設けられた貫通孔155,156を貫通するようにそれぞれ圧入により本体151に植設されている。   The ground member 150 has a cap-shaped main body 151, a pair of ground terminals 152 and 153, and a conductive member 154, and is disposed on the other end side in the longitudinal direction of the outer shell 101. The main body 151 is made of a heat-resistant synthetic resin such as silicon resin, for example. The pair of ground terminals 152 and 153 are made of metal such as aluminum or copper, for example, and are implanted in the main body 151 by press-fitting so as to penetrate through holes 155 and 156 provided in the main body 151.

導電部材154は、導電性を有する略方形板状の部材であって、本体151のヒートシンク120側に配置されており、例えば接着やビス止め等で本体151に固定されている。導電部材154には、本体151の貫通孔155,156に対応させた位置に貫通孔157,158が設けられており、一対のアース端子152,153は、導電部材154の貫通孔157,158に挿入した状態で、例えば半田付け、溶接、導電性接着剤による接着等で導電部材154と電気的に接続されている。   The conductive member 154 is a substantially rectangular plate-like member having conductivity, and is disposed on the heat sink 120 side of the main body 151, and is fixed to the main body 151 by, for example, bonding or screwing. The conductive member 154 is provided with through holes 157 and 158 at positions corresponding to the through holes 155 and 156 of the main body 151, and the pair of ground terminals 152 and 153 are connected to the through holes 157 and 158 of the conductive member 154. In the inserted state, it is electrically connected to the conductive member 154 by, for example, soldering, welding, adhesion with a conductive adhesive, or the like.

導電部材154は、ヒートシンク120側の面159がヒートシンク120と面接触しており、この接触により導電部材154とヒートシンク120とが電気的に接続されている。なお、導電部材154とヒートシンク120との電気的な接続は単なる接触によるものに限定されず、例えば半田付け、溶接、導電性接着剤による接着等により電気的だけでなく機械的にも接続された構成であっても良い。   The conductive member 154 has a surface 159 on the heat sink 120 side in surface contact with the heat sink 120, and the conductive member 154 and the heat sink 120 are electrically connected by this contact. It should be noted that the electrical connection between the conductive member 154 and the heat sink 120 is not limited to a simple contact, and is connected not only electrically but also mechanically, for example, by soldering, welding, adhesion with a conductive adhesive, or the like. It may be a configuration.

なお、導電部材154は本発明には必須ではなく、ヒートシンク120とアース端子152,153とが電気的に接続されていれば導電部材154の有無は問わない。したがって、例えば、アース端子152,153とヒートシンク120とが直接電気的に接続された構成であっても良い。   Note that the conductive member 154 is not essential to the present invention, and the presence or absence of the conductive member 154 does not matter as long as the heat sink 120 and the ground terminals 152 and 153 are electrically connected. Therefore, for example, the ground terminals 152 and 153 and the heat sink 120 may be directly electrically connected.

図5は、LEDランプの照明器具への取り付け状態を説明するための図である。図5に示すように、照明器具200は、筐体210、口金ソケット220、点灯回路230およびアース端子受け治具240を備える。   FIG. 5 is a diagram for explaining an attachment state of the LED lamp to the lighting fixture. As shown in FIG. 5, the lighting fixture 200 includes a casing 210, a base socket 220, a lighting circuit 230, and a ground terminal receiving jig 240.

筐体210は、例えば、下面が開口した略箱状であって、上面211が天井等への取付面となっており、内面212は光反射面となっており、内部にLEDランプ100が収納されている。また、筐体210の上面211には点灯回路230が取り付けられており、筐体210の内部には、口金ソケット220およびアース端子受け治具240が互いに対向するように取り付けられている。   The housing 210 has, for example, a substantially box shape with an open bottom surface, the top surface 211 is a mounting surface for a ceiling or the like, the inner surface 212 is a light reflecting surface, and the LED lamp 100 is housed inside. Has been. Further, a lighting circuit 230 is attached to the upper surface 211 of the housing 210, and a base socket 220 and a ground terminal receiving jig 240 are attached to the inside of the housing 210 so as to face each other.

口金ソケット220には、口金ピン142,143と電気的に接続される板ばね状の給電端子221,222が内蔵されており、口金ソケット220に設けられたピン孔223,224に口金ピン142,143を差し込むと、口金ピン142,143と給電端子221,222とが電気的に接続される。   The base socket 220 incorporates leaf spring-shaped power supply terminals 221 and 222 that are electrically connected to the base pins 142 and 143, and the base pins 142 and 224 are provided in the pin holes 223 and 224 provided in the base socket 220. When the terminal 143 is inserted, the base pins 142 and 143 and the power supply terminals 221 and 222 are electrically connected.

点灯回路230は、商用交流電源からの交流電圧を直流電圧に変換し、その直流電圧を口金ソケット220を介してLEDランプ100の口金140に供給し、LED114を点灯させる。当該点灯回路230と商用交流電源とは、電力供給線231を介して接続されており、点灯回路230と口金ソケット220の一対の給電端子221,222とは電力供給線232を介して接続されている。なお、電力供給線232は、給電端子221,222側が2つの配線232a,232bに分岐されており、それぞれ給電端子221,222と電気的に接続されている。   The lighting circuit 230 converts an AC voltage from a commercial AC power source into a DC voltage, supplies the DC voltage to the base 140 of the LED lamp 100 via the base socket 220, and turns on the LED 114. The lighting circuit 230 and the commercial AC power supply are connected via a power supply line 231, and the lighting circuit 230 and the pair of power supply terminals 221 and 222 of the base socket 220 are connected via a power supply line 232. Yes. Note that the power supply line 232 branches from the power supply terminals 221 and 222 into two wirings 232a and 232b, and is electrically connected to the power supply terminals 221 and 222, respectively.

図6は、LEDランプおよび照明器具の回路図である。なお、図においてLED114は数を省略して記載している。図6に示すように、点灯回路230は、例えば定電流直流回路233を備える。なお、定電流直流回路233は、例えば整流ダイオード、平滑コンデンサなどを利用して構成することが考えられる。   FIG. 6 is a circuit diagram of an LED lamp and a lighting fixture. In the figure, the number of LEDs 114 is omitted. As shown in FIG. 6, the lighting circuit 230 includes a constant current DC circuit 233, for example. Note that the constant current DC circuit 233 may be configured using, for example, a rectifier diode or a smoothing capacitor.

図5に戻って、アース端子受け治具240には、アース端子152,153と電気的に接続される板ばね状の導電端子241,242が内蔵されており、アース端子受け治具240に設けられた端子孔243,244にアース端子152,153を差し込むと、アース端子152,153と導電端子241,242とが電気的に接続される。   Returning to FIG. 5, the ground terminal receiving jig 240 includes leaf spring-like conductive terminals 241 and 242 that are electrically connected to the ground terminals 152 and 153. When the ground terminals 152 and 153 are inserted into the terminal holes 243 and 244 formed, the ground terminals 152 and 153 and the conductive terminals 241 and 242 are electrically connected.

導電端子241,242は、アース線245を介して接地されている。アース線245は、導電端子241,242側が2つの導電線245a,245bに分岐しており、それぞれ導電端子241,242と電気的に接続されている。   The conductive terminals 241 and 242 are grounded via a ground wire 245. The ground wire 245 branches from the conductive terminals 241 and 242 into two conductive wires 245a and 245b, and is electrically connected to the conductive terminals 241 and 242 respectively.

アース端子受け治具240は、筐体210の内面212に取り付けられた治具保持部材250によって保持されている。治具保持部材250は、アース端子受け治具240を口金ソケット220側に付勢する付勢体251,252と、アース端子受け治具240のランプ長手方向への移動を一定範囲に規制するためにアース端子受け治具240のスリット溝246,247内に嵌め込まれた爪部253,254とを有し、アース端子受け治具240は治具保持部材250に対して摺動可能である。   The ground terminal receiving jig 240 is held by a jig holding member 250 attached to the inner surface 212 of the housing 210. The jig holding member 250 restricts the movement of the ground terminal receiving jig 240 in the longitudinal direction of the lamp and the biasing bodies 251 and 252 that bias the ground terminal receiving jig 240 toward the cap socket 220 side. And claw portions 253 and 254 fitted in the slit grooves 246 and 247 of the ground terminal receiving jig 240, and the ground terminal receiving jig 240 is slidable with respect to the jig holding member 250.

LEDランプ100を照明器具200に取り付ける際は、まず、アース部材150のアース端子152,153をアース端子受け治具240の端子孔243,244に差し込みながらアース部材150でアース端子受け治具240を口金ソケット220から遠ざける方向に移動させる。これにより、アース端子受け治具240と口金ソケット220との間の距離が広がる。次に、LEDランプ100を口金ソケット220側に移動させ、口金140の口金ピン142,143を口金ソケット220のピン孔223,224に差し込んで口金140を口金ソケット220に装着する。アース端子受け治具240が付勢体251,252により口金ソケット220側へ付勢されているため、アース端子受け治具240と口金ソケット220とによってLEDランプ100は保持される。   When attaching the LED lamp 100 to the lighting fixture 200, first, the earth terminal 150 is attached to the earth terminal 150 while the earth terminals 152 and 153 of the earth member 150 are inserted into the terminal holes 243 and 244 of the earth terminal receiver jig 240. Move in a direction away from the base socket 220. Thereby, the distance between the ground terminal receiving jig 240 and the base socket 220 is increased. Next, the LED lamp 100 is moved to the base socket 220 side, the base pins 142 and 143 of the base 140 are inserted into the pin holes 223 and 224 of the base socket 220, and the base 140 is attached to the base socket 220. Since the ground terminal receiving jig 240 is biased toward the base socket 220 by the biasing bodies 251 and 252, the LED lamp 100 is held by the ground terminal receiving jig 240 and the base socket 220.

LEDランプ100を装着することによって、口金ピン142,143と給電端子221,222とが電気的に接続されるため、照明器具200から口金140へ直流電圧が入力される。また、ヒートシンク120は、導電部材154、アース端子152,153、導電端子241,242およびアース線245を介して接地される。   By mounting the LED lamp 100, the base pins 142 and 143 and the power supply terminals 221 and 222 are electrically connected, so that a DC voltage is input from the lighting fixture 200 to the base 140. The heat sink 120 is grounded via the conductive member 154, the ground terminals 152 and 153, the conductive terminals 241 and 242, and the ground wire 245.

ヒートシンク120はアルミニウム製であるため導電性を有する。したがって、LEDモジュール110や点灯回路230の漏電等によりヒートシンク120に電流が流れる可能性がある。しかしながら、LEDランプ100を照明器具200に取り付けた状態において、ヒートシンク120は接地された状態になっており電位を持たない。したがって、ヒートシンク120に触れても感電することがない。   Since the heat sink 120 is made of aluminum, it has conductivity. Therefore, current may flow through the heat sink 120 due to leakage of the LED module 110 or the lighting circuit 230. However, when the LED lamp 100 is attached to the lighting fixture 200, the heat sink 120 is grounded and has no potential. Therefore, there is no electric shock even when the heat sink 120 is touched.

なお、カバー130が導電性の材料からなる場合も、カバー130はヒートシンク120に取り付けられているため、接地された状態となっており、カバー130に触れても感電のおそれがない。   Even when the cover 130 is made of a conductive material, since the cover 130 is attached to the heat sink 120, it is in a grounded state, and there is no fear of electric shock even if the cover 130 is touched.

[変形例]
以上、本発明に係るLEDランプおよび照明器具を実施の形態に基づいて具体的に説明してきたが、本発明に係るLEDランプおよび照明器具は、上記の実施の形態に限定されない。例えば、以下のような変形例が考えられる。
[Modification]
As mentioned above, although the LED lamp and lighting fixture which concern on this invention have been concretely demonstrated based on embodiment, the LED lamp and lighting fixture which concern on this invention are not limited to said embodiment. For example, the following modifications can be considered.

(変形例1)
図7は、変形例1に係るLEDランプ等を示す平面図である。なお、照明器具の口金ソケットおよびアース端子受け治具は断面で表している。図7に示すように、変形例1に係るLEDランプ300は、環形蛍光ランプ型である点において、上記実施の形態に係るLEDランプ100と大きく相違する。以下では、相違点のみを説明し、LEDランプ100と同様の点ついては重複を避けるため説明を省略する。
(Modification 1)
FIG. 7 is a plan view showing an LED lamp and the like according to the first modification. Note that the base socket and the earth terminal receiving jig of the lighting fixture are shown in cross section. As shown in FIG. 7, the LED lamp 300 according to the first modification is greatly different from the LED lamp 100 according to the above-described embodiment in that it is an annular fluorescent lamp type. Below, only a difference is demonstrated and description is abbreviate | omitted in order to avoid duplication about the same point as the LED lamp 100. FIG.

図7に示すように、変形例1に係るLEDランプ300は、環形蛍光灯の代替品であって、LEDモジュール310、ヒートシンク320、カバー330、口金340およびアース部材350を備え、ヒートシンク320とカバー330とで外殻301が構成されている。   As shown in FIG. 7, the LED lamp 300 according to the first modification is an alternative to the annular fluorescent lamp, and includes an LED module 310, a heat sink 320, a cover 330, a base 340, and a ground member 350, and the heat sink 320 and the cover. 330 forms an outer shell 301.

LEDモジュール310は、長尺円弧状の基板311を有し、基板311に複数のLED313が基板311の長手方向に沿って一列に、すなわち円弧状に一列に実装されている。ヒートシンク320とカバー330も、基板311の形状に合わせた長尺円弧状であって、それらで構成される外殻301も長尺円弧状である。   The LED module 310 has a long arc-shaped substrate 311, and a plurality of LEDs 313 are mounted on the substrate 311 in a line along the longitudinal direction of the substrate 311, that is, in an arc shape. The heat sink 320 and the cover 330 also have a long arc shape that matches the shape of the substrate 311, and the outer shell 301 constituted by them also has a long arc shape.

LEDランプ300の口金340は照明器具の口金ソケット220に装着され、アース部材350はアース端子受け治具240に装着される。図7に示す例では、口金ソケット220およびアース端子受け治具240は照明器具の筐体(不図示)に固定されておらず、筐体とは電力供給線232またはアース線245によって繋がっているだけである。したがって、口金ソケット220およびアース端子受け治具240ではLEDランプ300を保持することはできず、LEDランプ300は筐体に別途取り付けられたランプ保持部材(不図示)によって保持される。   The base 340 of the LED lamp 300 is mounted on the base socket 220 of the lighting fixture, and the ground member 350 is mounted on the ground terminal receiving jig 240. In the example shown in FIG. 7, the base socket 220 and the ground terminal receiving jig 240 are not fixed to the housing (not shown) of the lighting fixture, and are connected to the housing by the power supply line 232 or the ground wire 245. Only. Therefore, the base socket 220 and the ground terminal receiving jig 240 cannot hold the LED lamp 300, and the LED lamp 300 is held by a lamp holding member (not shown) separately attached to the housing.

このように、本発明に係るLEDランプは直管蛍光灯の代替品に限定されず、環形蛍光灯やU形蛍光灯など直管蛍光灯以外の形の蛍光灯の代替品であっても良く、外殻の形状は直線状に限定されず、例えば円弧状やU字状等であっても良い。   Thus, the LED lamp according to the present invention is not limited to a substitute for a straight tube fluorescent lamp, but may be a substitute for a fluorescent lamp other than a straight tube fluorescent lamp, such as a ring-shaped fluorescent lamp or a U-shaped fluorescent lamp. The shape of the outer shell is not limited to a linear shape, and may be, for example, an arc shape or a U shape.

(変形例2)
図8は、変形例2に係る口金およびアース部材の装着構造を説明するための模式図であって、(a)は口金回転前の状態、(b)は口金回転後の状態を示す。
(Modification 2)
FIGS. 8A and 8B are schematic diagrams for explaining the mounting structure of the base and the ground member according to the modification 2. FIG. 8A shows a state before the base is rotated, and FIG. 8B shows a state after the base is rotated.

口金ソケット220は、口金140を回転させ装着する装着構造であっても良い。その場合、口金ソケット220の一対の給電端子221,222は、図8(a)に示すように口金140を回転させる前は、一対の口金ピン142,143と電気的に接続されず、かつ、図8(b)に示すように口金140を回転させ終えた後は、一対の口金ピン142,143と電気的に接続される位置に配置することが考えられる。   The base socket 220 may have a mounting structure in which the base 140 is rotated and mounted. In that case, the pair of power supply terminals 221 and 222 of the base socket 220 are not electrically connected to the pair of base pins 142 and 143 before the base 140 is rotated as shown in FIG. As shown in FIG. 8B, after the base 140 has been rotated, it is conceivable that the base 140 is disposed at a position where it is electrically connected to the pair of base pins 142 and 143.

このように、口金140を回転させ終えた後、すなわち口金ソケット220に口金140を装着し終えた際に、口金ピン142,143と給電端子221,222とが電気的に接続される構成とすることで、照明器具200にLEDランプ100を取り付ける途中でLEDランプ100に電流が流れてしまうのを防止することができ、ランプ取り付け時の安全性をより向上させることができる。   As described above, after the base 140 is rotated, that is, when the base 140 is completely attached to the base socket 220, the base pins 142 and 143 and the power supply terminals 221 and 222 are electrically connected. Thus, it is possible to prevent a current from flowing through the LED lamp 100 during the attachment of the LED lamp 100 to the lighting fixture 200, and it is possible to further improve the safety when the lamp is attached.

また、アース端子受け治具240は、アース部材150を回転させ装着する装着構造であっても良い。その場合、アース端子受け治具240の一対の導電端子241,242は、図8(a)に示すようにアース部材150を回転させる前は、一対のアース端子152,153と電気的に接続されず、かつ、図8(b)に示すようにアース部材150を回転させた後は、一対のアース端子152,153と電気的に接続される位置に配置することが考えられる。   Further, the ground terminal receiving jig 240 may have a mounting structure for rotating and mounting the ground member 150. In that case, the pair of conductive terminals 241 and 242 of the ground terminal receiving jig 240 are electrically connected to the pair of ground terminals 152 and 153 before the ground member 150 is rotated as shown in FIG. In addition, after the ground member 150 is rotated as shown in FIG. 8B, it is conceivable that the ground member 150 is disposed at a position that is electrically connected to the pair of ground terminals 152 and 153.

このように、アース部材150を回転させ終えた後、すなわちアース端子受け治具240にアース部材150を装着し終えた際に、アース端子152,153と導電端子241,242とが電気的に接続される構成とすることで、照明器具200にLEDランプ100を取り付ける途中で、アース端子152,153を介してヒートシンク120に電流が流れ、LEDランプ100を持つ手を離して落としてしまう等の事故を防止することができ、ランプ取り付け時の安全性をより向上させることができる。   As described above, after the earth member 150 is rotated, that is, when the earth member 150 is completely attached to the earth terminal receiving jig 240, the earth terminals 152 and 153 and the conductive terminals 241 and 242 are electrically connected. By adopting such a configuration, an accident such as a current flowing through the heat sink 120 via the ground terminals 152 and 153 during the attachment of the LED lamp 100 to the luminaire 200 and the hand holding the LED lamp 100 being released is dropped. Can be prevented, and the safety when the lamp is mounted can be further improved.

(変形例3)
本発明に係る口金の構成は、上記実施の形態に限定されず、例えば以下のよう構成であっても良い。図9は、変形例3に係る口金を示す図であって、(a)は斜視図、(b)は正面図、(c)は平面図、(d)は底面図、(e)は左側面図、(f)は右側面図である。
(Modification 3)
The configuration of the base according to the present invention is not limited to the above embodiment, and may be configured as follows, for example. 9A and 9B are diagrams showing a base according to the third modification, in which FIG. 9A is a perspective view, FIG. 9B is a front view, FIG. 9C is a plan view, FIG. 9D is a bottom view, and FIG. (F) is a right side view.

図9に示す変形例3に係る口金440は、一対の口金ピン441,442が突設されたピン突設面443よりも口金ピン441,442の突出方向に膨出した凸部444と、ピン突設面443よりも前記突出方向と反対方向に凹入した凹部445とを有する。この口金440が装着される口金ソケット(不図示)は、口金440の凸部444に対応する位置に凹部を有し、かつ、口金440の凹部445に対応する位置に凸部を有する。   A base 440 according to Modification 3 shown in FIG. 9 includes a convex portion 444 that bulges in a protruding direction of the base pins 441 and 442 from a pin protruding surface 443 on which a pair of base pins 441 and 442 protrudes, and a pin And a recess 445 recessed in the direction opposite to the projecting direction from the projecting surface 443. A base socket (not shown) to which the base 440 is attached has a concave portion at a position corresponding to the convex portion 444 of the base 440 and a convex portion at a position corresponding to the concave portion 445 of the base 440.

このような構成により、本発明に係るLEDランプが既存の照明器具に誤って取り付けられることを防止できるとともに、本発明に係る照明器具に既存のLEDランプが誤って取り付けられることも防止できる。なお、このような効果を得るためには、必ずしも凸部444と凹部445の両方が不可欠なわけではなく、いずれか一方のみであっても良い。   With such a configuration, it is possible to prevent the LED lamp according to the present invention from being erroneously attached to the existing lighting fixture, and it is also possible to prevent the existing LED lamp from being erroneously attached to the lighting fixture according to the present invention. In order to obtain such an effect, both the convex portion 444 and the concave portion 445 are not necessarily indispensable, and only one of them may be provided.

また、口金440の凹部445には、口金ソケットに設けられた被掛止部(不図示)に係合される掛止部446が設けられており、前記被掛止部に掛止部446を係合させることによっても口金440は口金ソケットに保持される。例えば、口金ソケットの被掛止部は鉤状のものであって、口金440を口金ソケットに回転装着する際に、口金400に設けられた掛止部446の鉤孔447に被掛止部を引っ掛けることで、口金400は口金ソケットに掛止される。このような構成とすることで、照明器具からのLEDランプの落下を防止することができる。   The recess 445 of the base 440 is provided with a latching portion 446 that is engaged with a latched portion (not shown) provided in the base socket, and the latching portion 446 is provided on the latched portion. The base 440 is also held in the base socket by engaging the base. For example, the hooked portion of the base socket is bowl-shaped, and when the base 440 is rotationally mounted on the base socket, the hooked portion 447 is provided in the hook hole 447 provided in the base 400. By hooking, the base 400 is hooked to the base socket. By setting it as such a structure, the fall of the LED lamp from a lighting fixture can be prevented.

(変形例4)
また、本発明に係る口金は以下のような構成であっても良い。図10は、変形例4に係る口金を示す図であって、(a)は斜視図、(b)は正面図、(c)は平面図、(d)は底面図、(e)は左側面図、(f)は右側面図である。

(F) is a right side view.

図10に示す変形例4に係る口金540は、変形例3に係る口金440と同形状の、一対の口金ピン541,542、ピン突設面543、凸部544および凹部545を有し、凹部545には鉤孔547を有する掛止部546が設けられている。さらに、凹部545には、第2の掛止部548が設けられている。第2の掛止部を設けることで、より照明器具から落下し難いLEDランプとすることができる。   A base 540 according to Modification 4 shown in FIG. 10 has a pair of base pins 541, 542, a pin projecting surface 543, a convex portion 544, and a concave portion 545 having the same shape as the base 440 according to Modification 3. 545 is provided with a hooking portion 546 having a fist hole 547. Further, the recess 545 is provided with a second hooking portion 548. By providing the 2nd latching part, it can be set as the LED lamp which is hard to fall from a lighting fixture.
