（第１の実施形態）
図１は、本実施形態に係る照明装置の略図的平面図である。図２は、図１の線ＩＩ−ＩＩにおける略図的断面図である。図１に示すように、照明装置１は、外装管１０を備えている。外装管１０は、円筒状に形成されている。本実施形態において、外装管１０は、透明なガラス管により構成されている。 (First embodiment)
FIG. 1 is a schematic plan view of a lighting device according to the present embodiment. FIG. 2 is a schematic cross-sectional view taken along line II-II in FIG. As shown in FIG. 1, the lighting device 1 includes an outer tube 10. The outer tube 10 is formed in a cylindrical shape. In the present embodiment, the outer tube 10 is made of a transparent glass tube.

外装管１０の両端部には、ソケット１１ａ、１１ｂが取り付けられている。   Sockets 11 a and 11 b are attached to both ends of the outer tube 10.

外装管１０の内部には、ＬＥＤ発光素子１４が収納されている。ＬＥＤ発光素子１４は、支持基板１５と、配線基板１６と、複数のＬＥＤ１７とを有する。   An LED light emitting element 14 is housed inside the outer tube 10. The LED light emitting element 14 includes a support substrate 15, a wiring substrate 16, and a plurality of LEDs 17.

複数のＬＥＤ１７は、配線基板１６に実装されている。複数のＬＥＤ１７は、ｙ方向に沿って直線状に等間隔に配置されている。ＬＥＤ１７は、どのような色の光を発するものであってもよく、例えば、白色光、青色光、赤色光、緑色光、黄色光等を発するものであってもよい。   The plurality of LEDs 17 are mounted on the wiring board 16. The plurality of LEDs 17 are linearly arranged at equal intervals along the y direction. The LED 17 may emit any color of light, for example, may emit white light, blue light, red light, green light, yellow light, or the like.

配線基板１６は、ｙ方向に沿って延びる矩形状に形成されている。配線基板１６は、上記複数のＬＥＤ１７の駆動回路及び配線が形成された基板である。この配線基板１６を介して、複数のＬＥＤ１７がソケット１１ａ、１１ｂに電気的に接続されている。配線基板１６は、例えばフレキシブルプリント基板（Ｆｌｅｘｉｂｌｅ Ｐｒｉｎｔｅｄ Ｃｉｒｃｕｉｔ）により構成することができる。   The wiring board 16 is formed in a rectangular shape extending along the y direction. The wiring board 16 is a board on which driving circuits and wirings for the plurality of LEDs 17 are formed. A plurality of LEDs 17 are electrically connected to the sockets 11a and 11b via the wiring board 16. The wiring board 16 can be configured by, for example, a flexible printed circuit board (Flexible Printed Circuit).

配線基板１６は、支持基板１５により支持されている。支持基板１５も、ｙ方向に沿って延びる矩形状に形成されている。支持基板１５は、配線基板１６及び複数のＬＥＤ１７を好適に支持し得るものである限りにおいて特に限定されない。支持基板１５は、例えば、樹脂、ガラス、セラミックス、金属等により形成することができる。   The wiring substrate 16 is supported by the support substrate 15. The support substrate 15 is also formed in a rectangular shape extending along the y direction. The support substrate 15 is not particularly limited as long as it can suitably support the wiring substrate 16 and the plurality of LEDs 17. The support substrate 15 can be formed of, for example, resin, glass, ceramics, metal, or the like.

ＬＥＤ発光素子１４は、複数の固定部材１３により外装管１０に対して固定されている。複数の固定部材１３は、ｙ方向に沿って等間隔に配置されている。複数の固定部材１３のそれぞれは、弾性体からなるバネ部１３ａと、バネ部１３ａの両端部に設けられた一対の支持部１３ｂとを有する。この一対の支持部１３ｂにより、ＬＥＤ発光素子１４の支持基板１５が支持されている。本実施形態では、具体的には、支持基板１５には、凹部を有する係合部１５ａが設けられており、その係合部１５ａの凹部に支持部１３ｂが挿入されることによりＬＥＤ発光素子１４が固定されている。   The LED light emitting element 14 is fixed to the outer tube 10 by a plurality of fixing members 13. The plurality of fixing members 13 are arranged at equal intervals along the y direction. Each of the plurality of fixing members 13 includes a spring portion 13a made of an elastic body and a pair of support portions 13b provided at both ends of the spring portion 13a. The support substrate 15 of the LED light emitting element 14 is supported by the pair of support portions 13b. In the present embodiment, specifically, the support substrate 15 is provided with an engagement portion 15a having a recess, and the support portion 13b is inserted into the recess of the engagement portion 15a, whereby the LED light emitting element 14 is provided. Is fixed.

本実施形態では、バネ部１３ａは、円弧状に形成されている。バネ部１３ａの曲率半径は、外装管１０に収納されていない状態では、外装管１０の内径よりも大きい。固定部材１３は、バネ部１３ａが縮径した状態で外装管１０内に配置されている。このため、固定部材１３は、バネ部１３ａの付勢力によって外装管１０に固定されている。   In the present embodiment, the spring portion 13a is formed in an arc shape. The radius of curvature of the spring portion 13 a is larger than the inner diameter of the outer tube 10 when not stored in the outer tube 10. The fixing member 13 is disposed in the outer tube 10 with the spring portion 13a having a reduced diameter. For this reason, the fixing member 13 is fixed to the outer tube 10 by the urging force of the spring portion 13a.

なお、固定部材１３は、例えば、ＰＥＴ、プロピレンカーボネート、ポリプロピレン、ポリエチレン等の樹脂、鉄や銅などの金属、ステンレスなどの合金等の弾性体により形成することができる。   The fixing member 13 can be formed of, for example, an elastic body such as a resin such as PET, propylene carbonate, polypropylene, or polyethylene, a metal such as iron or copper, or an alloy such as stainless steel.

以上説明したように、本実施形態では、バネ部１３ａが縮径した状態で外装管１０内に配置されることにより、外装管１０に強固に固定された固定部材１３によりＬＥＤ発光素子１４が固定されている。このため、ＬＥＤ発光素子１４を強固に固定することができる。   As described above, in the present embodiment, the LED light emitting element 14 is fixed by the fixing member 13 firmly fixed to the outer tube 10 by being arranged in the outer tube 10 with the spring portion 13a having a reduced diameter. Has been. For this reason, the LED light emitting element 14 can be firmly fixed.

また、弾性体からなるバネ部１３ａを介してＬＥＤ発光素子１４が固定されているため、例えば外装管１０に衝撃が加わった場合であっても、ＬＥＤ発光素子１４に衝撃が加わり難い。従って、ＬＥＤ発光素子１４の損傷を抑制することができる。   Further, since the LED light emitting element 14 is fixed via the spring portion 13a made of an elastic body, for example, even when an impact is applied to the outer tube 10, it is difficult for the LED light emitting element 14 to be impacted. Therefore, damage to the LED light emitting element 14 can be suppressed.

また、本実施形態の照明装置１であれば、まず、外装管１０の内径よりも外径が小さな円筒であって、外表面が樹脂等で被覆された管内にＬＥＤ発光素子１４が固定された固定部材１３を挿入し、次に、その固定部材１３を外装管１０内に挿入し、最後に、管のみを抜き取ることにより容易に製造することができる。また、このように製造することにより、ガラスからなる外装管１０の内壁に傷等が生じることを効果的に抑制することができる。   Further, in the lighting device 1 of the present embodiment, first, the LED light emitting element 14 is fixed in a tube having an outer diameter smaller than the inner diameter of the outer tube 10 and having an outer surface coated with a resin or the like. It can be easily manufactured by inserting the fixing member 13 and then inserting the fixing member 13 into the outer tube 10 and finally extracting only the tube. Moreover, it can suppress effectively that a damage | wound etc. arise in the inner wall of the exterior tube 10 which consists of glass by manufacturing in this way.

さらに、ＬＥＤ発光素子１４の固定に接着剤等を用いていないため、ＬＥＤ発光素子１４の交換も容易に行うことができる。   Furthermore, since no adhesive or the like is used to fix the LED light emitting element 14, the LED light emitting element 14 can be easily replaced.

なお、本実施形態では、帯状の固定部材１３を複数設ける例について説明したが、ｙ方向に延びる細長形状の固定部材をひとつのみ設けるようにしてもよい。   In the present embodiment, an example in which a plurality of belt-like fixing members 13 are provided has been described. However, only one elongated fixing member extending in the y direction may be provided.

以下、本発明を実施した好ましい形態の他の例について説明する。以下の説明において、上記第１の実施形態と実質的に共通の機能を有する部材を共通の符号で参照し、説明を省略する。   Hereinafter, other examples of preferred embodiments of the present invention will be described.
