Description

本発明は、半導体発光素子を用いた直管形ランプ、およびこの直管形ランプを用いた照明装置に関する。   The present invention relates to a straight tube lamp using a semiconductor light emitting element and an illumination device using the straight tube lamp.

一般に、直管形蛍光ランプを用いた照明器具が多く使用されているが、このような既設の照明器具に、直管形蛍光ランプに代えて使用可能な光源として低消費電力かつ長寿命なＬＥＤ素子を用いた直管形ランプが提案されている。   In general, lighting fixtures using straight tube fluorescent lamps are often used. However, low power consumption and long-life LEDs are used as light sources that can be used instead of straight tube fluorescent lamps in such existing lighting fixtures. A straight tube lamp using the element has been proposed.

この直管形ランプは、直管形蛍光ランプと同じ管長とされ、その両端には直管形蛍光ランプと同じ一対の口金ピンが突出されたＧ１３形の口金が設けられており、直管形蛍光ランプと同様に、既設の照明器具に配設された一対のソケット間に装着可能としている。直管形ランプ内には、アクリル樹脂などの樹脂製の透光性カバー内に、複数のＬＥＤ素子を実装した基板を有する光源ユニット、および直管形蛍光ランプ用の安定器からソケット内の端子およびランプピンを通じて供給される交流電力を直流電力に変換して光源ユニットの各ＬＥＤ素子に供給して各ＬＥＤ素子を点灯させる電源回路が収容されている。   This straight tube lamp has the same tube length as that of the straight tube fluorescent lamp, and is provided with a G13-shaped base having a pair of base pins protruding from the same end as the straight tube fluorescent lamp. Like a fluorescent lamp, it can be mounted between a pair of sockets provided in an existing lighting fixture. In the straight tube lamp, a light source unit having a substrate mounted with a plurality of LED elements in a translucent cover made of resin such as acrylic resin, and a terminal in a socket from a ballast for a straight tube fluorescent lamp A power supply circuit that converts AC power supplied through the lamp pin into DC power and supplies it to each LED element of the light source unit to turn on each LED element is housed.

実用新案登録第３１５２５０９号公報Utility Model Registration No. 3152509

直管形ランプの点灯時には、光源ユニットの各ＬＥＤ素子からの熱の影響が光源ユニットを収容する透光性カバーに作用し、この透光性カバーが熱膨張し、また、消灯後には、熱膨張した透光性カバーが熱収縮することになり、各ＬＥＤ素子からの熱の影響で透光性カバーが伸縮しやすい。   When the straight tube lamp is turned on, the influence of heat from each LED element of the light source unit acts on the translucent cover that accommodates the light source unit, and the translucent cover expands thermally. The expanded translucent cover is thermally contracted, and the translucent cover is easily expanded and contracted by the influence of heat from each LED element.

直管形ランプを構成する光源ユニット、透光性カバーおよび口金が全て一体化されている場合、透光性カバーの伸縮の影響を光源ユニットや口金が受け、光源ユニットに伸縮の負荷がかかり、口金を装着するソケットに負荷がかかったり口金のソケットに対する接続や保持に影響を及ぼすおそれがある。   When the light source unit, translucent cover and base that make up the straight tube lamp are all integrated, the light source unit and base are affected by the expansion and contraction of the translucent cover, and the light source unit is subjected to expansion and contraction. There is a possibility that a load is applied to the socket to which the base is mounted, and that the connection and holding of the base to the socket are affected.

本発明は、このような点に鑑みなされたもので、透光性カバーの伸縮による影響を防止できる直管形ランプ、およびこの直管形ランプを用いた照明装置を提供することを目的とする。   The present invention has been made in view of the above points, and an object thereof is to provide a straight tube lamp capable of preventing the influence of expansion and contraction of a translucent cover, and an illumination device using the straight tube lamp. .

本発明の直管形ランプは、半導体発光素子を有する光源ユニットを備える。光源ユニットを収容する透光性カバーを備える。光源ユニットと一体化され、透光性カバーの移動を許容する状態で透光性カバーの端部を覆う端部カバーを備える。   The straight tube lamp of the present invention includes a light source unit having a semiconductor light emitting element. A translucent cover that houses the light source unit is provided. An end cover is provided that is integrated with the light source unit and covers the end of the translucent cover in a state that allows the translucent cover to move.

本発明の直管形ランプによれば、透光性カバーの端部を覆う端部カバーを光源ユニットに一体化し、この端部カバーに対して透光性カバーの移動を許容するようにしたため、透光性カバーが熱膨張、熱収縮しても、光源ユニットや端部カバーに影響を与えるのを防止することが期待できる。   According to the straight tube lamp of the present invention, the end cover that covers the end of the translucent cover is integrated into the light source unit, and the translucent cover is allowed to move with respect to the end cover. Even if the translucent cover is thermally expanded and contracted, it can be expected to prevent the light source unit and the end cover from being affected.

図４に示すように、照明装置11は、直管形蛍光ランプ２灯用タイプの埋込形照明器具である照明器具12、およびこの照明器具12に用いられる２本の直管形ランプ13を備えている。   As shown in FIG. 4, the lighting device 11 includes a lighting fixture 12 that is an embedded lighting fixture of the type for two straight tube fluorescent lamps, and two straight tube lamps 13 used in the lighting fixture 12. I have.

照明器具12は、天井面に埋め込み設置される下面開放形の長尺な器具本体15、この器具本体15の長手方向の両端に対向配置されて各直管形ランプ13の端部がそれぞれ装着される２組のソケット16，17、および器具本体15に配置されて直管形ランプ13を点灯させる専用電源である点灯装置18を備えている。なお、以下、直管形ランプ13の一端側を装着する一端側のソケット16を第１のソケット16と呼び、直管形ランプ13の他端側を装着する他端側のソケット17を第２のソケット17と呼ぶ。   The luminaire 12 is an elongated lower fixture body 15 that is embedded in the ceiling surface, and is opposed to both ends of the fixture body 15 in the longitudinal direction. Two sets of sockets 16 and 17 and a lighting device 18 which is disposed in the fixture body 15 and is a dedicated power source for lighting the straight tube lamp 13. Hereinafter, the socket 16 on one end where one end of the straight tube lamp 13 is mounted is referred to as a first socket 16, and the socket 17 on the other end where the other end of the straight tube lamp 13 is mounted is the second. Called socket 17.

本実施形態の照明器具12は、例えば、直管形蛍光ランプを使用する既設の照明器具の器具本体15のみをそのまま使用し、直管形ランプ13と、この直管形ランプ専用のソケット16，17および点灯装置18とを組み合わせた照明器具12としてリニューアルするものである。あるいは、直管形ランプ13と、この直管形ランプ専用のソケット16，17および点灯装置18とを使用する照明器具12を新設する場合でも、直管形蛍光ランプ用の既存の器具本体15を流用し、これに直管形ランプ13、ソケット16，17および点灯装置18を組み合わせた照明器具12として設置するものである。   The lighting fixture 12 of this embodiment uses, for example, the fixture main body 15 of an existing lighting fixture that uses a straight tube fluorescent lamp as it is, and a straight tube lamp 13 and a socket 16 dedicated to this straight tube lamp, The lighting fixture 12 is renewed in combination with the lighting device 17 and the lighting device 18. Alternatively, even when a lighting fixture 12 that uses the straight tube lamp 13 and the sockets 16 and 17 dedicated to the straight tube lamp and the lighting device 18 is newly installed, the existing fixture body 15 for the straight tube fluorescent lamp is used. This is used as a lighting fixture 12 in which a straight tube lamp 13, sockets 16, 17 and a lighting device 18 are combined.

図１ないし図３に示すように、直管形ランプ13は、直管形蛍光ランプと同程度の管長および管径で直管形蛍光ランプと略同じ外観に形成されたカバー体21、およびこのカバー体21内に収容された光源ユニット22を備えている。   As shown in FIGS. 1 to 3, the straight tube lamp 13 includes a cover body 21 having a tube length and a tube diameter similar to those of the straight tube fluorescent lamp and formed in substantially the same appearance as the straight tube fluorescent lamp. A light source unit 22 accommodated in the cover body 21 is provided.

カバー体21は、透光性カバー24、およびこの透光性カバー24の両端部をそれぞれ閉塞するように覆う口金または端部キャップである端部カバー25，26を備えている。なお、以下、第１のソケット16に装着される直管形ランプ13の一端側の端部カバー25を第１の端部カバー25と呼び、第２のソケット17に装着される直管形ランプ13の他端側の端部カバー26を第２の端部カバー26と呼ぶ。   The cover body 21 includes a light-transmitting cover 24 and end covers 25 and 26 that are caps or end caps that cover both ends of the light-transmitting cover 24 so as to close each other. Hereinafter, the end cover 25 on one end side of the straight tube lamp 13 mounted on the first socket 16 will be referred to as a first end cover 25 and the straight tube lamp mounted on the second socket 17 will be described. The end cover 26 on the other end side of 13 is called a second end cover 26.

透光性カバー24は、例えば、透光性および拡散性を有する例えばアクリル樹脂などの樹脂材料によって長尺な円筒状に形成されている。   The translucent cover 24 is formed in a long cylindrical shape by a resin material such as an acrylic resin having translucency and diffusibility, for example.

端部カバー25，26は、例えば、絶縁性を有する合成樹脂製で、透光性カバー24の端面を覆う円板状の端面部27、およびこの端面部27の周辺部に環状に形成された周面部28を有するキャップ形状に形成されている。周面部28の内径は、透光性カバー24の外径よりも大きい寸法に形成されている。そして、第１の端部カバー25の端面には、光源ユニット22に電気的に接続される給電用の一対の口金ピンである接続部29が、直管形ランプ13の長手方向に沿って平行に突出されている。また、第２の端部カバー26の端面には、１本のアース接続用のアースピンである接続部30が、直管形ランプ13の管軸を中心として直管形ランプ13の長手方向に沿って突出されている。   The end covers 25 and 26 are made of, for example, an insulating synthetic resin, and are formed in a circular shape around the disc-shaped end surface portion 27 that covers the end surface of the translucent cover 24 and the periphery of the end surface portion 27. It is formed in a cap shape having a peripheral surface portion 28. The inner diameter of the peripheral surface portion 28 is formed to be larger than the outer diameter of the translucent cover 24. On the end face of the first end cover 25, a connection portion 29, which is a pair of base pins for power supply that is electrically connected to the light source unit 22, is parallel to the longitudinal direction of the straight tube lamp 13. Is protruding. Further, on the end face of the second end cover 26, a connection portion 30, which is a ground pin for ground connection, extends along the longitudinal direction of the straight tube lamp 13 around the tube axis of the straight tube lamp 13. Protruding.

光源ユニット22は、例えばＬＥＤ素子やＥＬ素子などの複数の半導体発光素子31が実装された細長い複数の基板32、およびこれら基板32を取り付けた細長い取付板33を備えている。   The light source unit 22 includes a plurality of elongated substrates 32 on which a plurality of semiconductor light emitting elements 31 such as LED elements and EL elements are mounted, and an elongated mounting plate 33 to which these substrates 32 are attached.

半導体発光素子31には、ＬＥＤ素子の場合、ＬＥＤチップが搭載された接続端子付きのＳＭＤ（Surface Mount Device）パッケージが用いられている。このＳＭＤパッケージは、パッケージ内に例えば青色光を発するＬＥＤチップが配置され、このＬＥＤチップをＬＥＤチップからの青色光の一部により励起されて黄色光を放射する黄色の蛍光体が混入された例えばシリコーン樹脂などの蛍光体層で封止されている。したがって、蛍光体層の表面が発光面となり、この発光面から白色系の光が放射される。   In the case of an LED element, the semiconductor light emitting element 31 uses an SMD (Surface Mount Device) package with a connection terminal on which an LED chip is mounted. In this SMD package, for example, an LED chip that emits blue light is arranged in the package, and this LED chip is mixed with a yellow phosphor that emits yellow light by being excited by a part of the blue light from the LED chip. Sealed with a phosphor layer such as silicone resin. Therefore, the surface of the phosphor layer becomes a light emitting surface, and white light is emitted from this light emitting surface.

取付板33は、例えば金属製で、長手方向の長さが透光性カバー24の長手方向の長さより長い寸法に形成され、その両端部に半導体発光素子31が配置される面側とは反対面側に向けて略直角に折曲形成されている。   The mounting plate 33 is made of metal, for example, and has a length in the longitudinal direction longer than the length in the longitudinal direction of the translucent cover 24. The mounting plate 33 is opposite to the surface side on which the semiconductor light emitting elements 31 are arranged at both ends. It is bent at a substantially right angle toward the surface side.

取付板33の一端の取付部34の外端面に一対の接続部29が固定され、取付板33の他端の取付部34の外端面に接続部30が固定されている。したがって、光源ユニット22の取付板33と各接続部29，30とが一体化されている。なお、取付板33と各接続部29，30とは互いに絶縁された状態で固定されている。   A pair of connection portions 29 is fixed to the outer end surface of the attachment portion 34 at one end of the attachment plate 33, and the connection portion 30 is fixed to the outer end surface of the attachment portion 34 at the other end of the attachment plate 33. Therefore, the mounting plate 33 of the light source unit 22 and the connection portions 29 and 30 are integrated. The mounting plate 33 and the connection portions 29 and 30 are fixed in a state of being insulated from each other.

一対の接続部29と基板32とが各電線35で電気的に接続され、一対の接続部29から基板32に実装された半導体発光素子31に給電可能に構成されている。接続部30と基板32のアース電位の部分とが電線36で電気的に接続されている。   The pair of connection portions 29 and the substrate 32 are electrically connected by the electric wires 35 so that power can be supplied from the pair of connection portions 29 to the semiconductor light emitting element 31 mounted on the substrate 32. The connecting portion 30 and the ground potential portion of the substrate 32 are electrically connected by an electric wire 36.

そして、光源ユニット22は、透光性カバー24のいずれか一方の端部から差し込まれた後、透光性カバー24の両端を覆うように端部カバー25，26が接続部29，30に固定され、これら透光性カバー24および端部カバー25，26で構成されるカバー体21内に収納されている。   Then, after the light source unit 22 is inserted from one end of the translucent cover 24, the end covers 25 and 26 are fixed to the connection portions 29 and 30 so as to cover both ends of the translucent cover 24. The light transmitting cover 24 and the end covers 25 and 26 are housed in a cover body 21.

端部カバー25，26と接続部29，30との固定は、例えば、端部カバー25，26に形成された孔部に接続部29，30をそれぞれ圧入することによって結合固定する。したがって、光源ユニット22の取付板33と各端部カバー25，26とが一体化されている。   The end covers 25, 26 and the connection portions 29, 30 are fixedly coupled by, for example, pressing the connection portions 29, 30 into holes formed in the end covers 25, 26, respectively. Therefore, the mounting plate 33 of the light source unit 22 and the end covers 25 and 26 are integrated.

透光性カバー24は、光源ユニット22や端部カバー25，26に対して所定の範囲で長手方向および径方向に移動可能な状態で、端部カバー25，26間に保持されている。   The translucent cover 24 is held between the end covers 25 and 26 so as to be movable in a longitudinal direction and a radial direction within a predetermined range with respect to the light source unit 22 and the end covers 25 and 26.

すなわち、直管形ランプ13の長手方向においては、透光性カバー24の端部と端部カバー25，26の端面部27の内面との間に透光性カバー24の伸縮を許容してその影響を低減あるいはなくすことが可能な所定の間隙ａ＋ｂを有し、また、直管形ランプ13の径方向においては、透光性カバー24の外周面と端部カバー25，26の周面部28の内周面との間に透光性カバー24の伸縮を許容してその影響を低減あるいはなくすことが可能な所定の間隙ｃ＋ｄを有している。   That is, in the longitudinal direction of the straight tube lamp 13, the translucent cover 24 is allowed to expand and contract between the end of the translucent cover 24 and the inner surfaces of the end surface portions 27 of the end covers 25 and 26. In the radial direction of the straight tube lamp 13, the outer peripheral surface of the translucent cover 24 and the peripheral surface portion 28 of the end covers 25, 26 are provided. A predetermined gap c + d is provided between the inner peripheral surface and the translucent cover 24 to allow expansion / contraction and reduce or eliminate the influence thereof.

したがって、透光性カバー24の長手方向の長さは、端部カバー25，26の端面部27が互いに対向する内面間の長さより短く、また、透光性カバー24の外径は、端部カバー25，26の周面部28の内径より小さい寸法関係を有している。   Therefore, the length of the translucent cover 24 in the longitudinal direction is shorter than the length between the inner surfaces of the end covers 25 and 26 where the end surface portions 27 face each other, and the outer diameter of the translucent cover 24 is the end portion. The dimensional relationship is smaller than the inner diameter of the peripheral surface portion 28 of the covers 25 and 26.

ただし、透光性カバー24の長手方向の長さは、端部カバー25，26の周面部28が互いに対向する先端面間の長さより長いとともに、端部カバー25，26のいずれか一方の端面部27の内面と他方の周面部28の先端面とが互いに対向する長さより長く、これにより、透光性カバー24が端部カバー25，26の周面部28間からは外れないように構成されている。   However, the length of the translucent cover 24 in the longitudinal direction is longer than the length between the front end faces of the end covers 25 and 26 facing each other, and the end face of one of the end covers 25 and 26 The inner surface of the portion 27 and the distal end surface of the other peripheral surface portion 28 are longer than the lengths facing each other, so that the translucent cover 24 does not come off between the peripheral surface portions 28 of the end covers 25 and 26. ing.

なお、例えば、透光性カバー24の一端側のみを第１の端部カバー25に保持し、透光性カバー24の他端側のみを第２の端部カバー26や光源ユニット22に対して移動可能に構成してもよい。   For example, only one end side of the translucent cover 24 is held by the first end cover 25, and only the other end side of the translucent cover 24 is attached to the second end cover 26 and the light source unit 22. It may be configured to be movable.

さらに、一対の接続部29と光源ユニット22の半導体発光素子31の発光面との位置関係は、直管形ランプ13をソケット16，17間に正しい装着位置に装着した状態で、半導体発光素子31の発光面が照明器具12の下方へ向いて所定の照射方向に光を照射できるように設定されている。   Further, the positional relationship between the pair of connection portions 29 and the light emitting surface of the semiconductor light emitting element 31 of the light source unit 22 is such that the semiconductor light emitting element 31 is in a state where the straight tube lamp 13 is mounted between the sockets 16 and 17 in the correct mounting position. Are set so that the light emitting surface can be directed downward of the luminaire 12 and light can be irradiated in a predetermined irradiation direction.

The first socket 16 includes an insulating resin socket main body 39 and a pair of power supply terminals 40 accommodated in the socket main body 39. I have. In the socket body 39, a pair of insertion holes are formed in a lamp mounting surface which is an inner surface facing the second socket 17, and a power supply terminal 40 is disposed inside each insertion hole. The pair of connection portions 29 of the straight tube lamp 13 are inserted into the pair of insertion holes, whereby the pair of connection portions 29 are electrically connected to the pair of power supply terminals 40, respectively. Alternatively, the lamp mounting surface of the socket body 39 is formed with a vertical groove communicating with the tip of the socket main body 39, and a pair of arc grooves are formed in communication with the vertical groove, and power is supplied to the inside of these arc grooves. Terminal 40 is arranged. In this case, by rotating the straight tube lamp 13 having the pair of connection portions 29 inserted in the longitudinal grooves around the tube axis, the pair of connection portions 29 move to the arc grooves and are electrically connected to the pair of power supply terminals 40, respectively. It is configured to be connected to.

また、第２のソケット17は、保持用およびアース接続用のソケットであり、絶縁性を有する樹脂製のソケット本体41、およびこのソケット本体41内に収容されるアース端子42を備えている。ソケット本体41は、第１のソケット16に対向する内側面であるランプ装着面から進退可能とするランプ取付部43を備えている。このランプ取付部43の中心に直管形ランプ13の接続部30が差し込まれる１つの差込孔が形成され、この差込孔の内側に接続部30と電気的に接続されるアース端子42が配置されている。ランプ取付部43は、ソケット本体41内に配置されるアース端子42あるいは別のスプリングによってソケット本体41からの突出方向に付勢されている。アース端子42は、器具本体15などに電気的に接続されている。   The second socket 17 is a holding and ground connection socket, and includes a resin socket body 41 having insulation properties and a ground terminal 42 accommodated in the socket body 41. The socket main body 41 includes a lamp mounting portion 43 that can be moved forward and backward from a lamp mounting surface that is an inner surface facing the first socket 16.

また、図４に示す点灯装置18は、商用交流電源が入力され、交流電力を直流電力に変換し、この直流電力を第１のソケット16の一対の給電端子40および直管形ランプ13の一対の接続部29を通じて光源ユニット22に供給する。   The lighting device 18 shown in FIG. 4 receives commercial AC power, converts AC power into DC power, and converts the DC power into a pair of power supply terminals 40 of the first socket 16 and a pair of straight tube lamps 13. The light source unit 22 is supplied through the connection portion 29 of

そうして、例えば天井面に設置されている既設の直管形蛍光ランプ用照明器具をリニューアルする場合には、直管形蛍光ランプ用点灯装置を器具本体15から取り外すか、直管形蛍光ランプ用点灯装置をそのまま残す場合には商用交流電源を供給する電源線を直管形蛍光ランプ用点灯装置から外し、直管形ランプ13の専用の点灯装置18を器具本体15に新たに取り付け、この点灯装置18に電源線を接続する。   Thus, for example, when renewing an existing lighting device for a straight tube fluorescent lamp installed on the ceiling surface, the lighting device for the straight tube fluorescent lamp is removed from the device main body 15, or the straight tube fluorescent lamp To leave the lighting device as it is, remove the power supply line for supplying commercial AC power from the lighting device for the straight tube fluorescent lamp, and attach a dedicated lighting device 18 for the straight tube lamp 13 to the fixture body 15, A power line is connected to the lighting device 18.

直管形蛍光ランプ用ソケットを器具本体15から外し、ソケット16，17を器具本体15に取り付け、点灯装置18と第１のソケット16とを電線によって電気的に接続する。   The socket for the straight tube fluorescent lamp is removed from the fixture main body 15, the sockets 16 and 17 are attached to the fixture main body 15, and the lighting device 18 and the first socket 16 are electrically connected by electric wires.

器具本体15のソケット16，17間に直管形ランプ13を装着する。この際、直管形ランプ13の第２の端部カバー26から突出する１本の接続部30を第２のソケット17のランプ取付部43の差込孔に差し込み、ランプ取付部43を付勢に抗してソケット本体41内に押し込んで、直管形ランプ13を全体的に第２のソケット17側に寄せながら、直管形ランプ13の第１の端部カバー25から突出する一対の接続部29を第１のソケット16の一対の差込孔に差し込んで一対の給電端子40に電気的に接続する。このとき、光源ユニット22の半導体発光素子31の発光面が照明器具12の下方へ向いて所定の照射方向に光を照射可能に直管形ランプ13を装着する。   A straight tube lamp 13 is mounted between the sockets 16 and 17 of the fixture body 15. At this time, one connecting portion 30 protruding from the second end cover 26 of the straight tube lamp 13 is inserted into the insertion hole of the lamp mounting portion 43 of the second socket 17 and the lamp mounting portion 43 is energized. A pair of connections projecting from the first end cover 25 of the straight tube lamp 13 while being pushed into the socket body 41 against the above and bringing the straight tube lamp 13 toward the second socket 17 as a whole. The portion 29 is inserted into the pair of insertion holes of the first socket 16 and electrically connected to the pair of power supply terminals 40. At this time, the straight tube lamp 13 is mounted so that the light emitting surface of the semiconductor light emitting element 31 of the light source unit 22 faces downward of the luminaire 12 and can irradiate light in a predetermined irradiation direction.

そして、点灯装置18の動作により、点灯装置18からの直流電力が第１のソケット16の一対の給電端子40および直管形ランプ13の一対の接続部29を通じて光源ユニット22に供給され、光源ユニット22の各半導体発光素子31が点灯し、各半導体発光素子31からの光が透光性カバー24を透過して照明器具12の下方の所定の照射方向に照射される。   Then, by the operation of the lighting device 18, DC power from the lighting device 18 is supplied to the light source unit 22 through the pair of power supply terminals 40 of the first socket 16 and the pair of connection portions 29 of the straight tube lamp 13. Each of the 22 semiconductor light emitting elements 31 is turned on, and light from each of the semiconductor light emitting elements 31 passes through the translucent cover 24 and is irradiated in a predetermined irradiation direction below the lighting fixture 12.

直管形ランプ13の点灯により、半導体発光素子31が発熱し、この熱が光源ユニット22や透光性カバー24に伝達される。特に、透光性カバー24は、樹脂製であるため、半導体発光素子31の熱の影響で顕著に熱膨張しやすい。熱膨張する透光性カバー24は、長手方向に伸長するとともに径方向に拡径する。   When the straight tube lamp 13 is turned on, the semiconductor light emitting element 31 generates heat, and this heat is transmitted to the light source unit 22 and the translucent cover 24. In particular, since the translucent cover 24 is made of resin, the light-transmitting cover 24 is prone to significantly expand due to the heat of the semiconductor light emitting element 31. The thermally transmissive cover 24 expands in the longitudinal direction and expands in the radial direction.

このとき、透光性カバー24と端部カバー25，26との間の長手方向には間隙ａ＋ｂが設けられているため、透光性カバー24が熱膨張によって長手方向に伸長するのを許容し、端部カバー25，26に負荷はかからない。また、透光性カバー24と端部カバー25，26との間の径方向には間隙ｃ＋ｄが設けられているため、透光性カバー24が熱膨張によって径方向に拡径するのを許容し、端部カバー25，26に負荷はかからない。したがって、透光性カバー24が熱膨張しても、端部カバー25，26および光源ユニット22を含む直管形ランプ13や、ソケット16，17などに負荷がかからず、破損が生じるようなことがない。   At this time, since a gap a + b is provided in the longitudinal direction between the translucent cover 24 and the end covers 25 and 26, the translucent cover 24 is allowed to extend in the longitudinal direction due to thermal expansion. The end covers 25 and 26 are not loaded. In addition, since a gap c + d is provided in the radial direction between the translucent cover 24 and the end covers 25 and 26, the translucent cover 24 is allowed to expand in the radial direction due to thermal expansion. The end covers 25 and 26 are not loaded. Therefore, even if the translucent cover 24 is thermally expanded, the straight tube lamp 13 including the end covers 25 and 26 and the light source unit 22 and the sockets 16 and 17 are not subjected to load and may be damaged. There is nothing.

一方、直管形ランプ13が消灯しているような低温時には、高温時に比べて透光性カバー24が熱収縮しているが、熱収縮した透光性カバー24が端部カバー25，26の周面部28間から外れることはなく、透光性カバー24は端部カバー25，26間に配置されている。   On the other hand, the translucent cover 24 is thermally shrunk at a low temperature when the straight tube lamp 13 is turned off compared to the high temperature, but the heat-shrinkable translucent cover 24 is not covered by the end covers 25 and 26. The translucent cover 24 is disposed between the end covers 25 and 26 without being detached from between the peripheral surface portions 28.

このように、本実施形態の直管形ランプ13は、透光性カバー24の端部を覆う端部カバー25，26を光源ユニット22に一体化し、これら端部カバー25，26に対して透光性カバー24の移動を許容するようにしたため、透光性カバー24が熱膨張、熱収縮しても、光源ユニット22や端部カバー25，26に影響を与えるのを防止することができる。   As described above, in the straight tube lamp 13 of the present embodiment, the end covers 25 and 26 that cover the ends of the translucent cover 24 are integrated with the light source unit 22, and the end covers 25 and 26 are transparent to the end covers 25 and 26. Since the movement of the light cover 24 is allowed, it is possible to prevent the light source unit 22 and the end covers 25 and 26 from being affected even if the light transmission cover 24 is thermally expanded or contracted.

しかも、接続部29，30も光源ユニット22に一体化しているため、透光性カバー24が熱膨張、熱収縮しても、接続部29，30によるソケット16，17との接続に影響を与えず、接続の信頼性を向上できる。   Moreover, since the connection portions 29 and 30 are also integrated with the light source unit 22, even if the translucent cover 24 is thermally expanded and contracted, the connection with the sockets 16 and 17 by the connection portions 29 and 30 is affected. Therefore, connection reliability can be improved.

なお、透光性カバー24のいずれか一方の端部を端部カバー25，26のいずれか一方に固定し、透光性カバー24のいずれか他方の端部のみを端部カバー25，26のいずれか他方や光源ユニット22に対して移動可能に構成してもよい。この場合にも、透光性カバー24の熱膨張、熱収縮による移動を許容できる。   One end of the translucent cover 24 is fixed to one of the end covers 25 and 26, and only the other end of the translucent cover 24 is fixed to the end covers 25 and 26. It may be configured to be movable with respect to either one or the light source unit 22. Also in this case, the translucent cover 24 can be allowed to move due to thermal expansion and contraction.

また、直管形ランプ13は、一対の接続部29にプラス、マイナスの専用の極性を持たせないようにする極性制御回路を備えていてもよい。この極性制御回路を備えることにより、例えば、一対の接続部29がそれぞれプラス用の給電端子40とマイナス用の給電端子40とのいずれに接続された場合でも点灯することができ、あるいは、極性が違って接続された場合に、点灯させないとともに光源ユニット22などに影響が生じないようにすることができる。   The straight tube lamp 13 may include a polarity control circuit that prevents the pair of connection portions 29 from having positive and negative polarities. By providing this polarity control circuit, for example, the pair of connection portions 29 can be lit regardless of whether they are connected to the positive power supply terminal 40 or the negative power supply terminal 40, respectively, or the polarity is If they are connected differently, it is possible not to turn on the light and to prevent the light source unit 22 from being affected.

また、照明装置11は、埋込形照明器具に限らず、直付形照明器具にも適用できる。   The lighting device 11 can be applied not only to the embedded lighting fixture but also to a direct-mounted lighting fixture.
