Description

この発明は、発光ユニットに関するものであり、特に、発光素子として複数のＬＥＤが配列された発光モジュールを複数配列した発光ユニットに係わるものである。   The present invention relates to a light emitting unit, and particularly to a light emitting unit in which a plurality of light emitting modules in which a plurality of LEDs are arranged as light emitting elements are arranged.

従来、一方向に複数の発光モジュールを配列させた発光ユニットが知られている。例えば特開２０１４−０９００５５号公報（特許文献１）には、支持体上に設けられた基板上に複数の発光素子（ＬＥＤ）を搭載してなる発光モジュールを用意し、この発光モジュールを一方向に複数配列させて支持体に設置した発光ユニットが開示されている。
かかる発光ユニットでは、隣り合う発光モジュール間の距離が長くなってしまうと、該発光モジュールの配列方向でのピッチ間隔にムラが生じることから、発光モジュールをできるだけ密接に配列することが必要である。 Conventionally, a light emitting unit in which a plurality of light emitting modules are arranged in one direction is known. For example, in Japanese Patent Application Laid-Open No. 2014-090055 (Patent Document 1), a light emitting module in which a plurality of light emitting elements (LEDs) are mounted on a substrate provided on a support is prepared, and the light emitting module is arranged in one direction. A light emitting unit that is arranged in a plurality and arranged on a support is disclosed.
In such a light-emitting unit, if the distance between adjacent light-emitting modules becomes long, the pitch interval in the arrangement direction of the light-emitting modules becomes uneven. Therefore, it is necessary to arrange the light-emitting modules as closely as possible.

ところで、このような発光ユニットにおいては、装置構成や使用環境、搭載されるＬＥＤの個体差などにより、各発光モジュールの光出力の寿命にはバラツキが生じやすい。当然、一部の発光モジュールが寿命末期に達する、又は、不具合（点灯不良）となった場合は、発光ユニット全体の配光分布に著しい悪影響を与えてしまい、それが製品寿命となる。
このような観点から、発光ユニットに設置される発光モジュールは、それぞれ個別に着脱自在とすることが装置設計上は好ましい。
しかしながら、近年はＬＥＤを高密度に実装した高光出力型の発光ユニットが求められており、発光モジュールを密接して配置させる必要があるところ、各発光モジュールの着脱作業時に、隣接する他の発光モジュールと不用意に接触してしまいやすく、これによって基板上のＬＥＤや接続端子を破損させてしまう可能性が高い。そのため、着脱作業が非常に煩雑になるという問題がある。 By the way, in such a light emitting unit, the life of the light output of each light emitting module is likely to vary due to the device configuration, usage environment, individual differences of mounted LEDs, and the like. Naturally, when some of the light emitting modules reach the end of their life or become defective (lighting failure), the light distribution of the entire light emitting unit is significantly adversely affected, which is the product life.
From such a viewpoint, it is preferable in terms of device design that the light emitting modules installed in the light emitting unit are individually detachable.
However, in recent years, there has been a demand for a high light output type light emitting unit in which LEDs are mounted at a high density, and it is necessary to closely arrange the light emitting modules. It is likely that the LED and the connection terminal on the substrate will be damaged. Therefore, there is a problem that the attaching / detaching work becomes very complicated.

特開２０１６−３９２０１号公報（特許文献２）には、このような不測の事故への対策として、ＬＥＤや接続端子を保護するために、発光モジュール上に透光性のカバー部材を設ける構造が記載されている。
図６、７にその概略構造が示されていて、基板１０１上に複数のＬＥＤ１０２が配列されてなる発光部１０３が形成された発光モジュール１００に、金属製の枠体１０５と、この上面に設けられた透光性の窓部材１０６とからなるカバー部材１０４を被嵌させたものである。これにより、ＬＥＤ１０２からなる発光部１０３の上方にカバー部材１０４の窓部材１０６が被せられるように配置されて、発光部１０３を保護するものである。 Japanese Patent Laying-Open No. 2006-39201 (Patent Document 2) has a structure in which a light-transmitting cover member is provided on a light emitting module in order to protect the LED and the connection terminal as a countermeasure against such an unexpected accident. Have been described.
The schematic structure is shown in FIGS. 6 and 7, and a light emitting module 100 in which a light emitting unit 103 in which a plurality of LEDs 102 are arranged on a substrate 101 is formed on a metal frame 105 and an upper surface thereof. A cover member 104 made of a transparent window member 106 is fitted. Thereby, it arrange | positions so that the window member 106 of the cover member 104 may be covered above the light emission part 103 which consists of LED102, and the light emission part 103 is protected.

しかして、かかる従来技術では、図７（Ｂ）に最もよく示されるように、カバー部材１０４の金属製の枠体１０５が、基板１０１の配列方向の側面に位置することになり、発光モジュール１００を複数配列するとき、このカバー部材１０４が隣接する発光モジュール１００間で干渉してしまい、密接配置することができず、発光モジュール１００の等間隔での配置も困難になって、全体の配光分布を悪化させる要因となっている。
さらには、カバー部材１０４の金属製の枠体１０５が、発光モジュール１００間での電流短絡の原因となりやすく、この点を考慮すると、発光モジュール１００間の離間距離を更に大きく確保する必要があり、配光分布の更なる悪化の原因となっている。 Thus, in the conventional technique, as best shown in FIG. 7B, the metal frame 105 of the cover member 104 is positioned on the side surface in the arrangement direction of the substrates 101, and the light emitting module 100. When a plurality of the light emitting modules are arranged, the cover members 104 interfere with each other between the adjacent light emitting modules 100 and cannot be closely arranged, making it difficult to arrange the light emitting modules 100 at equal intervals. It is a factor that deteriorates the distribution.
Furthermore, the metal frame 105 of the cover member 104 is likely to cause a current short circuit between the light emitting modules 100, and in consideration of this point, it is necessary to further secure a separation distance between the light emitting modules 100. This causes further deterioration of the light distribution.

この発明は、上記従来技術の問題点に鑑みて、複数のＬＥＤが設けられた発光部を有する基板と、当該基板を当接支持する支持体とからなる発光モジュールを、一方向に複数配列させて帯状の発光領域を形成する発光ユニットにおいて、発光モジュールの保守点検作業時に発光モジュールを損傷することなく、かつ、発光モジュールを密接配置することができるような構造を提供せんとするものである。   In view of the above-described problems of the prior art, the present invention has a plurality of light emitting modules arranged in one direction, each of which includes a substrate having a light emitting portion provided with a plurality of LEDs and a support body that abuts and supports the substrate. In the light emitting unit that forms a strip-shaped light emitting region, it is intended to provide a structure in which the light emitting module can be closely arranged without damaging the light emitting module during maintenance and inspection work of the light emitting module.

上記課題を解決するために、この発明の発光ユニットは、前記発光モジュールには、前記発光部を覆うようにカバー部材が着脱自在に設置されており、前記カバー部材は、前記発光部の全域を覆う保護部と、前記発光モジュールと係合する係合部とを有し、前記係合部は、前記発光モジュールの配列方向と直交する方向において、前記支持体と係合していることを特徴とする。
また、前記保護部は、前記発光モジュールの配列方向において、前記基板と同等以下の幅とされていることを特徴とする。
また、前記基板には、給電接続端子用の端子孔が設けられており、前記保護カバーは、該端子孔を覆うことがないようにされていることを特徴とする。
また、前記カバー部材には、前記発光部を避けた位置において、前記基板に向けて突出し、前記配列方向に延びる遮蔽部が設けられていることを特徴とする。 In order to solve the above problems, in the light emitting unit according to the present invention, a cover member is detachably installed on the light emitting module so as to cover the light emitting unit, and the cover member covers the entire area of the light emitting unit. It has a protective part to cover and an engaging part engaged with the light emitting module, and the engaging part is engaged with the support in a direction perpendicular to the arrangement direction of the light emitting modules. And
In addition, the protective part has a width equal to or less than that of the substrate in the arrangement direction of the light emitting modules.
The board is provided with a terminal hole for a power supply connection terminal, and the protective cover is configured not to cover the terminal hole.
Further, the cover member is provided with a shielding portion that protrudes toward the substrate and extends in the arrangement direction at a position avoiding the light emitting portion.

この発明の発光ユニットによれば、発光部を覆う保護カバーが、発光部の配列方向と直交する方向において支持体と係合しているので、該保護カバーが、発光モジュールの隣接配置を妨げることがなく、隣接配置した状態で該保護カバーの着脱が可能となり、発光モジュールを密着配置できて、全体の配光分布を良好なものとすることができる。
しかも、保護カバーの保護部の配列方向の幅を、基板の幅と同等以下にすることで更に発光モジュールを密接配置できる。
また、保護カバーは、発光モジュールの給電用の端子孔を覆うことがないので、発光モジュールの脱着作業が妨げられることがない。
更には、保護カバーの保護部に遮蔽部を設けることで、発光モジュールの保守点検作業時に工具などが発光部に侵入することを防止し、カバー部材が変形しても遮蔽部が支持体に当接することで、発光部に接触するようなことがない。 According to the light emitting unit of the present invention, the protective cover that covers the light emitting units is engaged with the support body in the direction orthogonal to the arrangement direction of the light emitting units, so that the protective cover prevents the adjacent arrangement of the light emitting modules. Therefore, the protective cover can be attached and detached in the state of being adjacently arranged, the light emitting modules can be closely arranged, and the overall light distribution can be improved.
In addition, the light emitting modules can be further closely arranged by setting the width of the protective portion of the protective cover in the arrangement direction to be equal to or smaller than the width of the substrate.
Further, since the protective cover does not cover the power supply terminal hole of the light emitting module, the attaching / detaching operation of the light emitting module is not hindered.
Furthermore, by providing a shielding part in the protection part of the protective cover, it is possible to prevent tools and the like from entering the light emitting part during maintenance and inspection work of the light emitting module, and even if the cover member is deformed, the shielding part contacts the support. By contacting, there is no contact with the light emitting part.

図１に示すように、本発明の発光ユニット１は、一方向に並列配置された複数の発光モジュール２、２を備えていて、この複数の発光モジュール２、２により配列方向に延びた帯状の発光領域を形成している。なお、図１においては、一部の発光モジュール２は、後述するカバー部材１０が取り除かれた状態が示されている。
図２は、図１の一部の拡大図で、ここでも一方の発光モジュール２はカバー部材１０が取り除かれて示されている。発光モジュール２は、複数のＬＥＤ３、３が配列されてなる発光部４を有する導電性の基板５と、この基板５を当接支持する支持体６とからなる。そして、基板５には給電接続端子用の端子孔５１、５１が設けられていて、隣接する発光モジュール２、２の端子孔５１、５１には給電接続端子７が取り付けられて、隣接する発光モジュール２、２を電気的に接続している。なお、図１に示すように、配列方向の両端部に位置する発光モジュール２、２の端子孔５１、５１には給電線８、８が接続されている。
発光モジュール２の基板５を支持する支持体６には取付け孔６１，６１が設けられていて、該支持体６は螺子等によりヒートシンク９に取り付けられている。このヒートシンク９は冷却水口９１からの冷却水によって冷却されている。 As shown in FIG. 1, the light emitting unit 1 of the present invention includes a plurality of light emitting modules 2 and 2 arranged in parallel in one direction, and the plurality of light emitting modules 2 and 2 extend in the arrangement direction. A light emitting region is formed. In FIG. 1, a part of the light emitting modules 2 is shown with a cover member 10 to be described later removed.
FIG. 2 is an enlarged view of a part of FIG. 1. Here, one light emitting module 2 is shown with the cover member 10 removed. The light emitting module 2 includes a conductive substrate 5 having a light emitting portion 4 in which a plurality of LEDs 3 and 3 are arranged, and a support 6 that abuts and supports the substrate 5. The substrate 5 is provided with terminal holes 51 and 51 for power supply connection terminals, and the power supply connection terminals 7 are attached to the terminal holes 51 and 51 of the adjacent light emitting modules 2 and 2 so as to be adjacent to each other. 2 and 2 are electrically connected. As shown in FIG. 1, feed lines 8 and 8 are connected to the terminal holes 51 and 51 of the light emitting modules 2 and 2 located at both ends in the arrangement direction.
Mounting holes 61, 61 are provided in the support 6 that supports the substrate 5 of the light emitting module 2, and the support 6 is attached to the heat sink 9 by screws or the like. The heat sink 9 is cooled by cooling water from a cooling water port 91.

発光モジュール２にはカバー部材１０が着脱自在に取り付けられており、このカバー部材１０は発光部４の上方を覆うように設けられている。
図３に示すように、カバー部材１０は、例えば、ポリカーボネート等の透光性材料や、ＡＢＳ樹脂等の非透光性材料が用いられている。
そして、このカバー部材１０は、保護部１１と係合部１２とからなり、保護部１１は、発光モジュール２の発光部４の全域を覆う形状である。また、係合部１２は、保護部１１から、発光モジュール２の配列方向（以下、単に配列方向という）と直交する方向（以下、単に直交方向という）に延びていて、先端側で略直角に曲げられている。そして、係合部１２の先端には係合突起１３が形成されている。
また、この図３に示す態様では、カバー部材１０には、下方の基板に向けて突出し、配列方向に延びる遮蔽部１４、１４が設けられている。 A cover member 10 is detachably attached to the light emitting module 2, and the cover member 10 is provided so as to cover the top of the light emitting unit 4.
As shown in FIG. 3, the cover member 10 is made of, for example, a translucent material such as polycarbonate or a non-translucent material such as ABS resin.
The cover member 10 includes a protection part 11 and an engagement part 12, and the protection part 11 has a shape that covers the entire area of the light emitting part 4 of the light emitting module 2. Further, the engaging portion 12 extends from the protection portion 11 in a direction (hereinafter simply referred to as an orthogonal direction) orthogonal to the arrangement direction of the light emitting modules 2 (hereinafter simply referred to as the alignment direction), and is substantially perpendicular to the distal end side. It is bent. An engagement protrusion 13 is formed at the tip of the engagement portion 12.
In the embodiment shown in FIG. 3, the cover member 10 is provided with shielding portions 14, 14 that protrude toward the lower substrate and extend in the arrangement direction.

図４にカバー部材１０が取り付けられた発光モジュール２の詳細が示されていて、図４（Ｂ）（Ｃ）に示されるように、カバー部材１０は、その係合部１２の係合突起１３が、支持体６の係合段部６２に弾性的に係合することで、該支持体６に着脱自在に取り付けられている。
このとき、カバー部材１０の保護部１１は、発光部４（ＬＥＤ３）に当接することなくその上方に間隙を持って位置する。そして、図４（Ａ）に示すように、保護部１１は、発光部４の全域を覆うような大きさとされている。
そして、図３および図４（Ａ）に示されるように、上記係合部１２は保護部１１よりも幅狭くされていて、カバー部材１０が発光モジュール２に取り付けられたとき、基板５の端子孔５１や支持体６の取付け孔６１を覆うことなく、露出する形状とされている。これにより、図１、２に示す、発光モジュール２のヒートシンク９への取り付け・取り外し作業や、基板５の端子孔５１への給電接続端子７の取り付け・取り外し作業がカバー部材１０に邪魔されることがなく円滑に行える。 4 shows details of the light emitting module 2 to which the cover member 10 is attached. As shown in FIGS. 4B and 4C, the cover member 10 has the engagement protrusion 13 of the engagement portion 12 thereof. Is detachably attached to the support 6 by elastically engaging with the engaging step 62 of the support 6.
At this time, the protective part 11 of the cover member 10 is positioned with a gap above the light emitting part 4 (LED 3) without contacting the light emitting part 4 (LED 3). And as shown to FIG. 4 (A), the protection part 11 is made into the magnitude | size which covers the whole region of the light emission part 4. As shown in FIG.
3 and 4A, the engaging portion 12 is narrower than the protective portion 11, and when the cover member 10 is attached to the light emitting module 2, the terminal of the substrate 5 is used. The hole 51 and the attachment hole 61 of the support 6 are not covered and are exposed. 1 and 2, the cover member 10 obstructs the attachment / detachment work of the light emitting module 2 to the heat sink 9 and the attachment / detachment work of the power supply connection terminal 7 to the terminal hole 51 of the substrate 5. It can be done smoothly.

また、保護部１１の配列方向の幅は、発光モジュール２の基板５の幅と同等以下とされている。つまり、カバー部材１０が、発光モジュール２の配列方向の両側縁からはみ出すことのない大きさとされている。
これにより、複数の発光モジュール２を配列する際に、隣接する発光モジュール２同士を密接して配置することができて、全体の発光分布を良好なものとすることができる。 Further, the width of the protection unit 11 in the arrangement direction is equal to or less than the width of the substrate 5 of the light emitting module 2. That is, the cover member 10 has a size that does not protrude from both side edges in the arrangement direction of the light emitting modules 2.
Thereby, when arranging the plurality of light emitting modules 2, the adjacent light emitting modules 2 can be arranged in close contact with each other, and the overall light emission distribution can be improved.

図５にカバー部材１０の変形実施例が示されていて、図３に示すように、カバー部材１０の保護部１１には、支持体６に向かって突出し、配列方向に延びる遮蔽部１４が設けられている。この遮蔽部１４は、図５（Ａ）に示すように、発光モジュール２の発光部４を避けた位置に設けられている。つまり、遮蔽部１４は、発光モジュール２の配列方向と直交する方向における発光部４の両端部の外側において、配列方向に延在している。
これにより、発光モジュール２の保守点検作業時、特に、取り外しや取付け時に工具等が発光部４を損傷したり、取り付け部品が発光部内に侵入したりすることが回避できる。また、カバー部材１０が何らかの事由により変形するようなことがあっても、遮蔽部１４が基板５に当接することで、発光部４にダメージを与えることがない。
なお、図５の実施例では、遮蔽部１４は保護部１１に設ける態様が示されているが、カバー部材１０の形状によっては係合部１２に設けるものであってもよく、この場合も、遮蔽部１４は、前記基板５の端子孔５１を覆うことなく、露出する位置および形状とされる。 FIG. 5 shows a modified embodiment of the cover member 10. As shown in FIG. 3, the protective portion 11 of the cover member 10 is provided with a shielding portion 14 that protrudes toward the support 6 and extends in the arrangement direction. It has been. As shown in FIG. 5A, the shielding part 14 is provided at a position avoiding the light emitting part 4 of the light emitting module 2. That is, the shielding part 14 extends in the arrangement direction outside the both ends of the light emitting part 4 in a direction orthogonal to the arrangement direction of the light emitting modules 2.
Thereby, it is possible to avoid a tool or the like from damaging the light emitting part 4 or an attachment component entering the light emitting part at the time of maintenance / inspection work of the light emitting module 2, especially during removal or attachment. Even if the cover member 10 is deformed for some reason, the light emitting unit 4 is not damaged by the shielding unit 14 coming into contact with the substrate 5.
In the embodiment of FIG. 5, the shielding part 14 is provided in the protection part 11. However, depending on the shape of the cover member 10, the shielding part 14 may be provided in the engaging part 12. The shielding part 14 has an exposed position and shape without covering the terminal hole 51 of the substrate 5.

以上のように、本発明の発光ユニットによれば、発光モジュールの発光部を覆うカバー部材を、発光モジュールの配列方向と直交する方向において、該発光モジュールの支持体に係合させているので、複数の発光モジュールを密接に配列することができて、発光ユニット全体の配光分布の向上に資するものである。
また、カバー部材に、基板に向かって突出し、配列方向に延びる遮蔽部を設けることで、発光モジュールの点検作業時などに工具等により発光部を損傷することを回避できる。 As described above, according to the light emitting unit of the present invention, the cover member that covers the light emitting portion of the light emitting module is engaged with the support of the light emitting module in a direction orthogonal to the arrangement direction of the light emitting modules. A plurality of light emitting modules can be closely arranged, which contributes to an improvement in the light distribution of the entire light emitting unit.
Further, by providing the cover member with a shielding portion that protrudes toward the substrate and extends in the arrangement direction, it is possible to avoid damaging the light emitting portion with a tool or the like at the time of checking the light emitting module.
