Description

本発明は、発光ダイオード素子から放射される光を波長変換する電球形LEDに関するものである。   The present invention relates to a light bulb shaped LED that converts the wavelength of light emitted from a light emitting diode element.

従来の電球形LEDによれば、発光ダイオード素子本体を蛍光材で覆い、発光ダイオードが放射する青色光を励起させて白色光などに波長変換するように構成されている。また、別手段として発光ダイオードが放射する青色光を蛍光材が塗布されたカバーにて波長変換するように構成されているものがある。(例えば特許文献1参照)   According to the conventional bulb-type LED, the light emitting diode element body is covered with a fluorescent material, and the blue light emitted from the light emitting diode is excited to convert the wavelength into white light or the like. As another means, there is a configuration in which the blue light emitted from the light emitting diode is wavelength-converted by a cover coated with a fluorescent material. (For example, see Patent Document 1)

特開2006−156187号公報JP 2006-156187 A

しかしながら、発光ダイオード素子本体を蛍光材で覆い、波長変換させて光源とした場合は、電球形LEDの光色を変更する際、発光ダイオード素子本体を変更する必要がある。また、蛍光材が塗布されたカバーにて波長変換する場合においても、外部カバーが波長変換カバーの外周部に固定されている。そのため電球形LEDの光色を変更するためには電球形LEDそのものを取り換えなければならないという課題がある。
さらに、外部カバーが落下等により破損・変形してしまった場合、電球形LEDの寿命が十分にあったとしても使用出来なくなる。
However, when the light emitting diode element body is covered with a fluorescent material and wavelength-converted to obtain a light source, it is necessary to change the light emitting diode element body when changing the light color of the bulb-type LED. Even when wavelength conversion is performed with a cover coated with a fluorescent material, the outer cover is fixed to the outer peripheral portion of the wavelength conversion cover. Therefore, in order to change the light color of the light bulb shaped LED, there is a problem that the light bulb shaped LED itself must be replaced.
Furthermore, if the outer cover is damaged or deformed due to dropping or the like, it cannot be used even if the light bulb-shaped LED has a sufficient life.

本発明は、電球形LEDの光色を簡単に変更可能とし、外部カバーが破損・変形した場合においても外部カバーの交換にて使用可能とする電球形LEDを提供することを目的とする。   An object of the present invention is to provide a light bulb-shaped LED that can easily change the light color of the light bulb-shaped LED and can be used by replacing the external cover even when the outer cover is damaged or deformed.

本発明にかかる電球形LEDは、 近紫外または青色光を発するLEDが実装されるLED光源基板と、前記LED光源基板が取り付けられる基板取付部、この基板取付部の周枠側からほぼ直角方向に立ち上げられて形成する筒形状部、この筒形状部の外周かつ前記基板取付部側に設けられる本体係合部を有する本体と、中空状の円筒形状をなし、内壁に前記本体係合部に着脱可能に係合するカバー係合部を有する弾性変形可能な弾性部と、この弾性部の一端から外方向に広がる略円形の連結部と、この連結部の端部から半球状に形成され、内部が中空状のカバー部と、前記カバー部の内壁に塗布され、前記LEDが発する光の波長を変換する蛍光体と、を有する。   A light bulb shaped LED according to the present invention includes an LED light source substrate on which an LED emitting near ultraviolet or blue light is mounted, a substrate mounting portion to which the LED light source substrate is mounted, and a direction substantially perpendicular to the peripheral frame side of the substrate mounting portion. A cylindrical part formed by being raised, a main body having a main body engaging part provided on the outer periphery of the cylindrical part and on the substrate mounting part side, and a hollow cylindrical shape, the inner wall is provided with the main body engaging part An elastically deformable elastic portion having a cover engaging portion that is detachably engaged, a substantially circular connecting portion extending outward from one end of the elastic portion, and a hemispherical shape from the end of the connecting portion, The inside has a hollow cover part, and the fluorescent substance apply | coated to the inner wall of the said cover part, and converts the wavelength of the light which LED emits.

本発明にかかる電球形LEDによれば、本体から波長変換カバーが取り外し可能となっているため、波長変換カバーを簡単に交換できるので、異なる光色の波長変換カバーに交換することにより容易に電球形LEDの光色が変更できる。   According to the light bulb shaped LED of the present invention, since the wavelength conversion cover can be removed from the main body, the wavelength conversion cover can be easily replaced. Therefore, the light bulb can be easily replaced by replacing the wavelength conversion cover with a different light color. The light color of the LED can be changed.

FIG. 2 is a cross-sectional view showing a cross section of the light bulb shaped LED of FIG. 1.

電球形LED本体100は、外郭を形成する外郭部110と、この外郭部110の内側に設けられる円筒形状の本体120と、この本体120の内部に収納されるLED電源装置130と、外郭部110の外方に延出する16枚の放熱部140と、本体120に取付けられるLED光源基板150と、このLED光源基板150を覆うように本体120に取付けられる透光カバー160と、を備える。   The light bulb-shaped LED main body 100 includes an outer portion 110 that forms an outer shell, a cylindrical main body 120 that is provided inside the outer shell 110, an LED power supply device 130 that is housed inside the main body 120, and an outer shell 110. 16 heat dissipating portions 140 extending outward, an LED light source substrate 150 attached to the main body 120, and a translucent cover 160 attached to the main body 120 so as to cover the LED light source substrate 150.

本体120は、放熱性を良くするために熱伝導性の高い金属、例えばアルミニウムにて構成されている。   The main body 120 is made of a metal having high thermal conductivity, such as aluminum, for improving heat dissipation.

本体120は、LED光源基板150及びこのLED光源基板150を覆う透光カバー160が取付けられる基板取付部121と、この基板取付部121と同一円周の筒形状部122と、この筒形状部122の外周に本体係合部123と、を一体的に形成している。   The main body 120 includes an LED light source substrate 150 and a substrate attachment portion 121 to which a translucent cover 160 covering the LED light source substrate 150 is attached, a cylindrical portion 122 having the same circumference as the substrate attachment portion 121, and the cylindrical shape portion 122. A main body engaging portion 123 is integrally formed on the outer periphery of the main body.

本体係合部123は、筒形状部122に溝状に形成され、リング状の凹形状となっている。   The main body engaging portion 123 is formed in a groove shape in the cylindrical portion 122 and has a ring-like concave shape.

LED電源装置130は、電源回路部131と、この電源回路部131から引き出され、口金部200に接続される口金用電線132と、同じく電源回路部131から引き出され、LED光源基板150に接続される基板用電線133と、を備える。   The LED power supply device 130 is drawn from the power supply circuit unit 131, the power supply circuit unit 131, and the base wire 132 connected to the base unit 200, and is also drawn from the power supply circuit unit 131 and connected to the LED light source substrate 150. Board electric wire 133.

LED光源基板150は、平面状に形成される基板151と、この基板151に実装される青色光(または近紫外光)を出力する複数の発光ダイオード素子152(以下、LED152という。)と、基板取付部121に取り付けるための基板取付穴153を有する。   The LED light source substrate 150 includes a substrate 151 formed in a planar shape, a plurality of light emitting diode elements 152 (hereinafter referred to as LEDs 152) that output blue light (or near ultraviolet light) mounted on the substrate 151, and a substrate. A board attachment hole 153 for attaching to the attachment part 121 is provided.

LED光源基板150は、LED152より放出される熱を電球形LED本体100へ効率良く放熱させるために本体120の基板取付部121に取付ネジ170により取り付けられている。LED光源基板150と基板取付部121との密着性を高めることによって、熱伝導率を高める(熱抵抗を低くする)ことができ、LED152が発光することによって生じる熱を、電球形LED本体100に熱伝導させて、放熱部140より放熱させる。   The LED light source substrate 150 is attached to the substrate attachment portion 121 of the main body 120 with attachment screws 170 in order to efficiently dissipate the heat emitted from the LED 152 to the light bulb-shaped LED main body 100. By increasing the adhesion between the LED light source substrate 150 and the substrate mounting portion 121, the thermal conductivity can be increased (the thermal resistance can be lowered), and the heat generated by the LED 152 emitting light is transmitted to the light bulb-shaped LED main body 100. The heat is conducted to dissipate heat from the heat dissipating part 140.

透光カバー160は、透光性のある合成樹脂であり、半球状に形成される半球カバー部161と、この半球カバー部161の外方に突出する取付平面部162と、LED光源基板150とともに基板取付部121に取り付けるためのカバー取付穴163と、を備える。   The translucent cover 160 is a translucent synthetic resin, together with a hemispherical cover portion 161 formed in a hemispherical shape, a mounting flat portion 162 projecting outward from the hemispherical cover portion 161, and the LED light source substrate 150. Cover attachment holes 163 for attaching to the substrate attachment portion 121.

半球カバー部161は、透明または透光性を有する。   The hemispherical cover part 161 has transparency or translucency.

取付平面部162は、取付ネジ170によって、LED光源基板150とともに本体120に共締めされ、半球カバー部161が、LED光源基板150のLED152及び基板120の配線を覆うことによって、直接ユーザーがLED152の電極などに触れて感電するのを防止している。   The mounting flat portion 162 is fastened together with the LED light source substrate 150 together with the LED light source substrate 150 by mounting screws 170, and the hemispherical cover portion 161 covers the LED 152 of the LED light source substrate 150 and the wiring of the substrate 120. Prevents electric shock from touching electrodes.

口金部200は、らせん状にねじ切られ、図示しない照明器具のランプソケット(E26形口金ソケットなど)に装着される。   The base part 200 is spirally threaded and attached to a lamp socket (such as an E26-type base socket) of a lighting fixture (not shown).

口金部200から給電された商用電源は、LED電源装置130へ電気的に接続され、LED電源装置130からLED光源基板150へ給電される。   The commercial power source fed from the base part 200 is electrically connected to the LED power source device 130 and fed from the LED power source device 130 to the LED light source substrate 150.

ランプソケットには、一般的に商用電源が供給されるので、ランプソケットに接続される口金部200から口金用電線132を介して電源回路部131に商用電源が供給され、LED152を点灯するための電力に変換して、基板用電線133を介してLED光源基板150へ給電する。   Since the commercial power is generally supplied to the lamp socket, the commercial power is supplied from the base part 200 connected to the lamp socket to the power circuit part 131 via the base wire 132, and the LED 152 is turned on. The power is converted into electric power, and power is supplied to the LED light source board 150 through the board electric wire 133.

図5は、図2の電球形LEDの断面を示す断面図であり、図6は、図1の電球形LEDの波長変換カバーを示す斜視図であり、図7は、図6の波長変換カバーの平面を示す平面図であり、図8は、図2の電球形LED本体の正面を示す正面図であり、図9は、図8の電球形LED本体から透光カバーを外した状態を示す正面図である。   5 is a cross-sectional view showing a cross section of the light bulb shaped LED of FIG. 2, FIG. 6 is a perspective view showing a wavelength conversion cover of the light bulb shaped LED of FIG. 1, and FIG. 7 is a wavelength conversion cover of FIG. FIG. 8 is a front view showing the front of the bulb-shaped LED main body of FIG. 2, and FIG. 9 shows a state in which the translucent cover is removed from the bulb-shaped LED main body of FIG. It is a front view.

波長変換カバー300は、中空状の円筒形状をなし、本体120に嵌め込まれる弾性変形可能な弾性部310と、この弾性部310の一端から外方向に広がる略円形の連結部320と、この連結部320の端部から半球状に形成され、内部が中空状のカバー部330と、を備える。この波長変換カバー300の弾性部310が本体120の周枠に嵌め込まれ、カバー部330がLED光源基板150および透光カバー160を覆う。   The wavelength conversion cover 300 has a hollow cylindrical shape, and is an elastically deformable elastic portion 310 fitted into the main body 120, a substantially circular connecting portion 320 extending outward from one end of the elastic portion 310, and the connecting portion. 320 is formed in a hemispherical shape from the end of 320, and has a hollow cover portion 330 inside. The elastic part 310 of the wavelength conversion cover 300 is fitted into the peripheral frame of the main body 120, and the cover part 330 covers the LED light source substrate 150 and the translucent cover 160.

この波長変換カバー300は、合成樹脂からなり、弾性部310と、連結部320と、カバー部330が一体的に形成されている。   The wavelength conversion cover 300 is made of synthetic resin, and an elastic portion 310, a connecting portion 320, and a cover portion 330 are integrally formed.

弾性部310は、内壁から内側に突出する凸部形状のカバー係合部311と、外壁にカバー係合部311を形成するときに生じる凹部312と、を有する。   The elastic portion 310 includes a convex cover engaging portion 311 that protrudes inward from the inner wall, and a concave portion 312 that is formed when the cover engaging portion 311 is formed on the outer wall.

カバー係合部311の凸部形状は、R形状(断面形状が半円形状)とし、本体係合部123との引っかかりを少なくして取り付け、取り外しが容易にできるようになっている。なお、本実施の形態では、カバー係合部311の凸部形状がR形状の場合について説明するが、他の形状、例えば、尖り形状でも構わなく、また、電球形LED本体100側に凸部、波長変換カバー300側に凹部を形成するようにしても構わない。   The convex shape of the cover engaging portion 311 is an R shape (the cross-sectional shape is a semicircular shape), and the cover engaging portion 311 can be attached and detached easily with little catching with the main body engaging portion 123. In this embodiment, the case where the convex shape of the cover engaging portion 311 is an R shape will be described. However, other shapes, for example, a sharp shape may be used, and the convex portion on the side of the bulb-shaped LED main body 100 may be used. A recess may be formed on the wavelength conversion cover 300 side.

凹部312は、カバー係合部311の凸部形状のR形状に応じた形となっており、弾性部310、カバー係合部311の弾性変形を補助する。   The concave portion 312 has a shape corresponding to the R shape of the convex shape of the cover engaging portion 311 and assists the elastic deformation of the elastic portion 310 and the cover engaging portion 311.

カバー部330は、半球中空状またはドーム状に形成され、内壁に蛍光体331が塗布されている。   The cover portion 330 is formed in a hemispherical hollow shape or a dome shape, and a phosphor 331 is applied to the inner wall.

蛍光体331は、LED152が発する青色の光(または紫外光)によって励起され、LED152が発する光の波長と異なる波長の光に波長変換する。この蛍光体331によって波長変換された光は、蛍光体331によって変換されずに透過するLED152が発する光と合成されて白色光となる。   The phosphor 331 is excited by blue light (or ultraviolet light) emitted from the LED 152 and converts the wavelength of light into light having a wavelength different from that of the light emitted from the LED 152. The light wavelength-converted by the phosphor 331 is combined with the light emitted from the LED 152 that is transmitted without being converted by the phosphor 331 and becomes white light.

蛍光体331は、たとえば赤色変換蛍光体、緑色変換蛍光体、青色変換蛍光体を混合した蛍光部材であり、この混合比を変えることにより多種類の蛍光体を作ることができる。   The phosphor 331 is a phosphor member in which, for example, a red conversion phosphor, a green conversion phosphor, and a blue conversion phosphor are mixed, and various types of phosphors can be produced by changing the mixing ratio.

ここで、波長変換カバー300の開口部分と、筒形状部122の外形と、カバー係合部311の外形の大きさの関係について説明する。   Here, the relationship among the opening portion of the wavelength conversion cover 300, the outer shape of the cylindrical portion 122, and the size of the outer shape of the cover engaging portion 311 will be described.

図10は、図5の電球形LEDの一部を拡大した拡大断面図である。   FIG. 10 is an enlarged cross-sectional view in which a part of the light bulb shaped LED of FIG. 5 is enlarged.

波長変換カバー300の開口部分の内径をφDとし、筒形状部122の最大外形をφEとし、カバー係合部311の最小外形をφFとする。   The inner diameter of the opening of the wavelength conversion cover 300 is φD, the maximum outer shape of the cylindrical portion 122 is φE, and the minimum outer shape of the cover engaging portion 311 is φF.

このとき、波長変換カバー300の開口部分の内径φDと、筒形状部122の最大外形φEの関係は、φD≧φEとなっている。   At this time, the relationship between the inner diameter φD of the opening of the wavelength conversion cover 300 and the maximum outer diameter φE of the cylindrical portion 122 is φD ≧ φE.

また、カバー係合部311の最小外形φFと、筒形状部122の最大外形φEの関係は、φE>φFとなっている。   Further, the relationship between the minimum outer diameter φF of the cover engaging portion 311 and the maximum outer diameter φE of the cylindrical portion 122 is φE> φF.

次に、電球形LED本体100に波長変換カバー300を着脱する工程について説明する。   Next, the process of attaching / detaching the wavelength conversion cover 300 to / from the light bulb shaped LED main body 100 will be described.

まず、電球形LED本体100に、波長変換カバー300を取付ける工程について説明する。   First, the process of attaching the wavelength conversion cover 300 to the light bulb shaped LED main body 100 will be described.

ユーザーは、波長変換カバー300のカバー部330を把持し、弾性部310を本体120に押し当てる。このとき、波長変換カバー300の弾性部310(開口部分)が、本体120の先端に接触した後、波長変換カバー300を押し込むと、弾性部310の内壁が本体120の外周に接触していき、次に、カバー係合部311が本体120の外周に接触して、弾性部310が押し広げられる。
The user holds the cover portion 330 of the wavelength conversion cover 300 and presses the elastic portion 310 against the main body 120. At this time, when the wavelength conversion cover 300 is pushed in after the elastic portion 310 (opening portion) of the wavelength conversion cover 300 contacts the tip of the main body 120, the inner wall of the elastic portion 310 contacts the outer periphery of the main body 120, Next, the cover engaging portion 311 comes into contact with the outer periphery of the main body 120, and the elastic portion 310 is expanded.

波長変換カバー300(弾性部310)の開口部の内径φDは、電球形LED本体100の本体係合部123を有する筒形状部122の最大外径φEより大きく設定されている。   The inner diameter φD of the opening of the wavelength conversion cover 300 (elastic portion 310) is set to be larger than the maximum outer diameter φE of the cylindrical portion 122 having the main body engaging portion 123 of the bulb-shaped LED main body 100.

また、カバー係合部311の凸部の最小外径φFは、筒形状部122の最大外径φEより小さく設定されており、また、合成樹脂で一体成形されているため、波長変換カバー300を電球形LED本体100へ取り付ける時にカバー係合部311の先端部を筒形状部122に当てて押し込むと、カバー係合部311が変形して、筒形状部122の側面を乗り越え、本体係合部123の位置に達すると、カバー係合部311が復元して本体係合部123に嵌り込む構造となっている。   Further, the minimum outer diameter φF of the convex portion of the cover engaging portion 311 is set to be smaller than the maximum outer diameter φE of the cylindrical portion 122 and is integrally formed of synthetic resin. When the cover engaging portion 311 is attached to the light bulb shaped LED main body 100 by pushing the tip of the cover engaging portion 311 against the cylindrical portion 122, the cover engaging portion 311 is deformed to get over the side surface of the cylindrical portion 122, and the main body engaging portion. When the position 123 is reached, the cover engaging portion 311 is restored and fitted into the main body engaging portion 123.

さらに、波長変換カバー300を電球形LED本体100に押し込むと、カバー係合部311が本体係合部123に嵌り込み、弾性部310の弾性変形が解除され、弾性部310の内壁が筒形状部122の外周に接触する。このようにして、波長変換カバー300を電球形LED本体100に取付けることができる。   Further, when the wavelength conversion cover 300 is pushed into the light bulb shaped LED main body 100, the cover engaging portion 311 is fitted into the main body engaging portion 123, the elastic deformation of the elastic portion 310 is released, and the inner wall of the elastic portion 310 is a cylindrical portion. It contacts the outer periphery of 122. In this way, the wavelength conversion cover 300 can be attached to the light bulb shaped LED main body 100.

次に、波長変換カバー300を電球形LED本体100から取り外す工程について説明する。   Next, a process of removing the wavelength conversion cover 300 from the light bulb shaped LED main body 100 will be described.

波長変換カバー300cは、中空状の円筒形状をなし、本体120cに嵌め込まれる弾性変形可能な弾性部310cと、この弾性部310cの一端から外方向に広がる略円形の連結部320と、この連結部320の端部から半球状に形成され、内部が中空状のカバー部330と、弾性部310cの端部から末広がりに広がるテーパー部350と、を備える。   The wavelength conversion cover 300c has a hollow cylindrical shape, and an elastically deformable elastic portion 310c fitted into the main body 120c, a substantially circular connecting portion 320 extending outward from one end of the elastic portion 310c, and the connecting portion The cover portion 330 is formed in a hemispherical shape from the end portion of 320 and has a hollow inside, and a tapered portion 350 that spreads from the end portion of the elastic portion 310c.

この波長変換カバー300cの弾性部310cが、本体120cの周枠に嵌め込まれ、カバー部330がLED光源基板150および透光カバー160を覆う。   The elastic part 310c of the wavelength conversion cover 300c is fitted into the peripheral frame of the main body 120c, and the cover part 330 covers the LED light source substrate 150 and the translucent cover 160.

この波長変換カバー300cは、合成樹脂からなり、弾性部310cと、連結部320と、カバー部330が一体的に形成されている。   The wavelength conversion cover 300c is made of synthetic resin, and an elastic portion 310c, a connecting portion 320, and a cover portion 330 are integrally formed.

波長変換カバー300cを電球形LED本体100cに取付ける工程について説明する。   The process of attaching the wavelength conversion cover 300c to the light bulb shaped LED main body 100c will be described.

まず、ユーザーが把持した波長変換カバー300cのテーパー部350を電球形LED本体100cの本体120cに押し当てる。   First, the tapered portion 350 of the wavelength conversion cover 300c gripped by the user is pressed against the main body 120c of the light bulb shaped LED main body 100c.

波長変換カバー300cを押し込み始めると、テーパー部350の内壁が操作部181に接触し、テーパー部350の内壁によって次第に操作部181が本体120cの内側に押し込まれていく。   When the wavelength conversion cover 300c is pushed in, the inner wall of the tapered portion 350 comes into contact with the operation portion 181 and the operation portion 181 is gradually pushed into the inside of the main body 120c by the inner wall of the tapered portion 350.

さらに波長変換カバー300cを押し込むと、本体120cの外郭にカバー係合部311が接触し、カバー係合部311と弾性部310cが弾性変形するとともに、弾性部310cが操作部181を本体120の内側に押し込んだ状態を維持する。   When the wavelength conversion cover 300c is further pushed in, the cover engaging portion 311 comes into contact with the outline of the main body 120c, the cover engaging portion 311 and the elastic portion 310c are elastically deformed, and the elastic portion 310c moves the operation portion 181 inside the main body 120. Keep pressed in.

テーパー部350および弾性部310cによって、操作部181が本体120cの内側に押し込まれた状態になると、接点部182が切り替えられ、LED電源装置130aは、LED152への電力供給を開始、つまりLED152を点灯させる。   When the operation unit 181 is pushed into the main body 120c by the taper unit 350 and the elastic unit 310c, the contact unit 182 is switched, and the LED power supply device 130a starts supplying power to the LED 152, that is, turns on the LED 152. Let

さらに、波長変換カバー300cが押し込まれ、カバー係合部311が本体係合部123に嵌まり込むと、弾性部310と本体係合部123の弾性変形が解除され、波長変換カバー300cが電球形LED本体100cに係合する。   Further, when the wavelength conversion cover 300c is pushed in and the cover engagement portion 311 is fitted into the main body engagement portion 123, the elastic deformation of the elastic portion 310 and the main body engagement portion 123 is released, and the wavelength conversion cover 300c is a light bulb shape. Engages with the LED body 100c.

次に、波長変換カバー300cを電球形LED本体100cから取り外す工程について説明する。   Next, the process of removing the wavelength conversion cover 300c from the light bulb shaped LED main body 100c will be described.

ユーザーは、波長変換カバー300cを把持し、電球形LED本体100cから引っ張ると、カバー係合部311が本体係合部123から外れ、カバー係合部311が外郭部110に接触して、弾性部310cとカバー係合部311が弾性変形する。   When the user holds the wavelength conversion cover 300c and pulls it from the light bulb shaped LED main body 100c, the cover engaging portion 311 comes off from the main body engaging portion 123, the cover engaging portion 311 comes into contact with the outer portion 110, and the elastic portion 310c and the cover engaging part 311 are elastically deformed.

さらに波長変換カバー300cを引っ張ると、操作部181がテーパー部350に接触し、次第に操作部181が外郭部110の外側方向に可動する。操作部181が外郭部110の外側方向に可動すると、接点部182が切り替えられ、LED電源装置130は、LED152への電力供給を停止、つまり、LED152を消灯させる。   When the wavelength conversion cover 300c is further pulled, the operation part 181 comes into contact with the taper part 350, and the operation part 181 gradually moves in the outward direction of the outer shell part 110. When the operation unit 181 is moved in the outer direction of the outer portion 110, the contact point 182 is switched, and the LED power supply device 130 stops supplying power to the LED 152, that is, turns off the LED 152.

この状態で、波長変換カバー300cを引っ張って外すと、弾性部310cとカバー係合部311の弾性変形が解除される。   In this state, when the wavelength conversion cover 300c is pulled and removed, the elastic deformation of the elastic portion 310c and the cover engaging portion 311 is released.

要するに、波長変換カバー300cが電球形LED本体100cに取付けられるとき、LED電源装置130aは、LED152に電力を供給して点灯させ、波長変換カバー300cが電球形LED本体100cから外されるとき、LED電源装置130aは、LED152への電力供給を遮断して消灯する。   In short, when the wavelength conversion cover 300c is attached to the light bulb shaped LED main body 100c, the LED power supply device 130a supplies power to the LED 152 to light it, and when the wavelength conversion cover 300c is removed from the light bulb shaped LED main body 100c, The power supply device 130a turns off the power supply to the LED 152.

このように、波長変換カバー300cを外したとき、LED152を消灯させるので、例えば、LED152が発する光をユーザーが直視するのを防ぐことができる。   As described above, when the wavelength conversion cover 300c is removed, the LED 152 is turned off, and thus, for example, it is possible to prevent the user from directly viewing the light emitted from the LED 152.

また、実施の形態1と同様に、電球形LED1000cの光色を変更することもでき、また、波長変換カバー300cが破損した場合に、電球形LED本体100cを変えずに、波長変換カバー300cを交換することもできる。   Similarly to the first embodiment, the light color of the light bulb-shaped LED 1000c can be changed, and when the wavelength conversion cover 300c is damaged, the wavelength conversion cover 300c is changed without changing the light bulb-shaped LED main body 100c. It can also be exchanged.

また、本実施の形態は、実施の形態2または実施の形態3の電球形LED1000a、1000bにも適用可能である。   The present embodiment is also applicable to the light bulb shaped LEDs 1000a and 1000b of the second or third embodiment.
