回路基板1は、例えばガラスエポキシ基板などの絶縁性の基板である。回路基板1上には、配線パターン(図示せず)が形成されている。配線パターンの端部には2つのコネクタ(41a、41b)が接続されている。図1及び図3に示した例では、一方のコネクタ41aは、回路基板1の1つの角部付近に配置されており、他方のコネクタ41bは、コネクタ41aが配置された角部とは対角に位置する角部付近に配置されている。ただし、このような例には限られず、コネクタ(41a、41b)は回路基板1上の任意の位置に配置することができる。コネクタ(41a、41b)には、COB基板3へ電力を供給するための回路を接続することができる。 The circuit board 1 is an insulating substrate such as a glass epoxy substrate. A wiring pattern (not shown) is formed on the circuit board 1. Two connectors (41a, 41b) are connected to the end of the wiring pattern. In the examples shown in FIGS. 1 and 3, one connector 41a is arranged near one corner of the circuit board 1, and the other connector 41b is diagonal to the corner where the connector 41a is arranged. It is located near the corner located in. However, the present invention is not limited to such an example, and the connectors (41a, 41b) can be arranged at arbitrary positions on the circuit board 1. A circuit for supplying electric power to the COB substrate 3 can be connected to the connectors (41a, 41b).

回路基板1は、第1開口部11、及び該第1開口部11の内周側に設けられた複数の突起部(12a〜12d)を有する。第1開口部11は、例えば長方形であり、COB基板3の発光部31が外部から観察可能な形状とすることが好ましい。また、複数の突起部(12a〜12d)は、COB基板3を固定するために、複数の突起部(12a〜12d)の少なくとも一部が、COB基板3と重なるように配置されていることが好ましい。 The circuit board 1 has a first opening 11 and a plurality of protrusions (12a to 12d) provided on the inner peripheral side of the first opening 11. The first opening 11 is preferably rectangular, for example, and preferably has a shape in which the light emitting portion 31 of the COB substrate 3 can be observed from the outside. Further, the plurality of protrusions (12a to 12d) are arranged so that at least a part of the plurality of protrusions (12a to 12d) overlaps with the COB substrate 3 in order to fix the COB substrate 3. preferable.

図1には、複数の突起部(12a〜12d)を第1開口部11の内周側に4つ設けた例を示したが、このような例には限られない。COB基板3を固定可能であれば、突起部を2個としてもよい。この場合、第1開口部11の内周側の対角の位置(12aと12c、または12bと12d)に設けるようにしてもよい。あるいは、突起部の数は3個でもよいし、5個以上であってもよい。 FIG. 1 shows an example in which four protrusions (12a to 12d) are provided on the inner peripheral side of the first opening 11, but the present invention is not limited to such an example. If the COB substrate 3 can be fixed, the number of protrusions may be two. In this case, it may be provided at diagonal positions (12a and 12c, or 12b and 12d) on the inner peripheral side of the first opening 11. Alternatively, the number of protrusions may be three or five or more.

スペーサ基板2は、回路基板1の裏面に接して配置され、第1開口部11と略同一形状の第2開口部21を有する。スペーサ基板2は、絶縁性材料により形成することができる。スペーサ基板2は、回路基板1の裏面に両面テープ等で接着するようにしてもよい。 The spacer substrate 2 is arranged in contact with the back surface of the circuit board 1 and has a second opening 21 having substantially the same shape as the first opening 11. The spacer substrate 2 can be formed of an insulating material. The spacer substrate 2 may be adhered to the back surface of the circuit board 1 with double-sided tape or the like.

図4に、図3のA−A線における発光装置101の断面斜視図を示す。図5に、図3のA−A線における発光装置101の断面図を示す。COB基板3は、第1開口部11及び第2開口部21の内側に配置されている。COB基板3は、平面形状が長方形であるサブマウント基板33を有する。 FIG. 4 shows a cross-sectional perspective view of the light emitting device 101 in line AA of FIG. FIG. 5 shows a cross-sectional view of the light emitting device 101 in line AA of FIG. The COB substrate 3 is arranged inside the first opening 11 and the second opening 21. The COB substrate 3 has a submount substrate 33 having a rectangular planar shape.

サブマウント基板33上には、例えば円形の発光部31、及び発光部31を囲む環状のダム材32が形成されている。ただし、このような例には限られず、発光部31の形状は長方形や多角形等、任意の形状とすることができる。発光部31には、ワイヤ35により接続された複数の発光素子34が実装され、発光素子34は蛍光体を含んだ樹脂36により封止されている。サブマウント基板33のベース材は、例えば表面に絶縁層を備えたアルミニウム等の金属材料である。ただし、このような例には限られず、サブマウント基板33のベース材は、アルミナからなるセラミックスや表面反射処理を施した窒化アルミニウムを用いることもできる。 On the submount substrate 33, for example, a circular light emitting portion 31 and an annular dam material 32 surrounding the light emitting portion 31 are formed. However, the present invention is not limited to such an example, and the shape of the light emitting unit 31 can be any shape such as a rectangle or a polygon. A plurality of light emitting elements 34 connected by wires 35 are mounted on the light emitting unit 31, and the light emitting elements 34 are sealed with a resin 36 containing a phosphor. The base material of the submount substrate 33 is, for example, a metal material such as aluminum having an insulating layer on the surface. However, the present invention is not limited to such an example, and the base material of the submount substrate 33 may be ceramics made of alumina or aluminum nitride subjected to surface reflection treatment.

サブマウント基板33の上面には、電力供給端子(37a〜37d)が形成されており、発光素子34と配線(図示せず)により接続されている。電力供給端子(37a〜37d)は、回路基板1の突起部(12a〜12d)に対応した位置に設けられている。突起部(12a〜12d)には、スルーホール(図示せず)が設けられており、回路基板1の表面に形成された配線パターン(図示せず)と突起部(12a〜12d)の裏面に形成された電極(図示せず)とを電気的に接続することができる。従って、突起部(12a〜12d)をそれぞれ電力供給端子(37a〜37d)に電気的に接続することにより、回路基板1上のコネクタ(41a、41b)から発光素子34に電力を供給することができる。このように、突起部(12a〜12d)は、COB基板3を回路基板1に固定する機能、及び回路基板1の配線とCOB基板3の配線とを導通させる機能を有している。 Power supply terminals (37a to 37d) are formed on the upper surface of the submount substrate 33, and are connected to the light emitting element 34 by wiring (not shown). The power supply terminals (37a to 37d) are provided at positions corresponding to the protrusions (12a to 12d) of the circuit board 1. Through holes (not shown) are provided in the protrusions (12a to 12d), and the wiring pattern (not shown) formed on the front surface of the circuit board 1 and the back surface of the protrusions (12a to 12d). The formed electrodes (not shown) can be electrically connected. Therefore, by electrically connecting the protrusions (12a to 12d) to the power supply terminals (37a to 37d), power can be supplied to the light emitting element 34 from the connectors (41a, 41b) on the circuit board 1. it can. As described above, the protrusions (12a to 12d) have a function of fixing the COB board 3 to the circuit board 1 and a function of conducting the wiring of the circuit board 1 and the wiring of the COB board 3.

複数の突起部(12a〜12d)の少なくとも一部は、COB基板3の一部に、半田により固定されていることが好ましい。例えば、突起部(12a〜12d)と電力供給端子(37a〜37d)とを半田リフローにより固定することができる。 It is preferable that at least a part of the plurality of protrusions (12a to 12d) is fixed to a part of the COB substrate 3 by soldering. For example, the protrusions (12a to 12d) and the power supply terminals (37a to 37d) can be fixed by solder reflow.

ただし、このような例には限られず、複数の突起部(12a〜12d)の少なくとも一部は、COB基板3の一部に、導電性接着材により固定されていてもよい。具体的には、電力供給端子(37a〜37d)にシート状の導電性接着材を配置しておき、突起部(12a〜12d)を圧着するようにしてもよい。 However, the present invention is not limited to such an example, and at least a part of the plurality of protrusions (12a to 12d) may be fixed to a part of the COB substrate 3 with a conductive adhesive. Specifically, a sheet-shaped conductive adhesive may be arranged at the power supply terminals (37a to 37d), and the protrusions (12a to 12d) may be crimped.

本実施形態に係る発光装置101は、回路基板1に、スペーサ基板2及びCOB基板3を一体化させているため、回路基板1を基台100にネジ止め等を行うことにより、発光装置101を基台に固定することができる。従って、回路基板1はホルダとしての機能を有しているともいえる。本開示の実施形態に係る発光装置101は、回路基板とホルダとを一体化したものとなっているため、発光装置101を一体部品として扱うことができる。そのため、ユーザは、発光装置101をヒートシンク等の基台へ容易に設置することができる。 In the light emitting device 101 according to the present embodiment, since the spacer board 2 and the COB board 3 are integrated with the circuit board 1, the light emitting device 101 can be attached by screwing the circuit board 1 to the base 100. Can be fixed to the base. Therefore, it can be said that the circuit board 1 has a function as a holder. Since the light emitting device 101 according to the embodiment of the present disclosure integrates the circuit board and the holder, the light emitting device 101 can be treated as an integrated component. Therefore, the user can easily install the light emitting device 101 on a base such as a heat sink.

発光装置101の基台への固定は、回路基板1に設けたネジ穴(14a、14b)及びスペーサ基板2に設けたネジ穴(22a、22b)を利用してネジ止めにより行うことができる。これにより、COB基板3を機械的に基台へ固定できる。この場合、放熱効果を高めるために、COB基板3と基台(ヒートシンク)との密着性をよくすることが好ましい。そのために、スペーサ基板2の厚さは、COB基板3に含まれるサブマウント基板33の厚さより薄いことが好ましい。 The light emitting device 101 can be fixed to the base by screwing using the screw holes (14a, 14b) provided in the circuit board 1 and the screw holes (22a, 22b) provided in the spacer board 2. As a result, the COB substrate 3 can be mechanically fixed to the base. In this case, in order to enhance the heat dissipation effect, it is preferable to improve the adhesion between the COB substrate 3 and the base (heat sink). Therefore, the thickness of the spacer substrate 2 is preferably thinner than the thickness of the submount substrate 33 included in the COB substrate 3.

図6に図3のB−B線における発光装置101の断面斜視図を示す。図7(a)及び(b)に図3のC−C線における発光装置101の断面図を示す。図7(a)は、発光装置101を基台100に固定する前の状態を示す。スペーサ基板2の厚さは、COB基板3に含まれるサブマウント基板33の厚さより厚さdだけ薄いものとする。従って、発光装置101を基台100に乗せただけの状態では基台100とスペーサ基板2との間に間隙dが形成される。 FIG. 6 shows a cross-sectional perspective view of the light emitting device 101 in line BB of FIG. 7 (a) and 7 (b) show a cross-sectional view of the light emitting device 101 in line CC of FIG. FIG. 7A shows a state before the light emitting device 101 is fixed to the base 100. The thickness of the spacer substrate 2 is thinner than the thickness of the submount substrate 33 included in the COB substrate 3 by a thickness d. Therefore, a gap d is formed between the base 100 and the spacer substrate 2 when the light emitting device 101 is simply placed on the base 100.

図7(b)に発光装置101を基台100に固定した状態を示す。図7(b)に示すように、回路基板1は、第1連結部151a、151bが撓み、突起部12a、12bでサブマウント基板33を基台100に押し付けている。回路基板1及びスペーサ基板2を基台100にネジ止めすることにより、間隙dをなくし、COB基板3を基台100に密着させることができる。 FIG. 7B shows a state in which the light emitting device 101 is fixed to the base 100. As shown in FIG. 7B, in the circuit board 1, the first connecting portions 151a and 151b are bent, and the submount substrate 33 is pressed against the base 100 by the protrusions 12a and 12b. By screwing the circuit board 1 and the spacer board 2 to the base 100, the gap d can be eliminated and the COB board 3 can be brought into close contact with the base 100.

上記のように、COB基板3に含まれるサブマウント基板33の厚さより薄いスペーサ基板2を回路基板1の裏面に配置した状態で回路基板1を基台100に固定した場合、回路基板1の突起部(12a〜12d)周辺にはストレス(応力)がかかる。そこで、発光装置101を基台100に固定したときに回路基板1に生じるストレスを緩和するために、COB基板3の一部が、複数の突起部(12a〜12d)の少なくとも一部に上下動可能に固定されていることが好ましい。そのための構成として、複数の突起部(12a〜12d)と回路基板1との間に、L字形のスリット(13a〜13d)を設けることが好ましい。図3に示すように、L字形のスリット(13a〜13d)を設けることにより、突起部(12a〜12d)は、回路基板1とそれぞれ第1連結部(151a〜151d)及び第2連結部(152a〜152d)により連結される。第1連結部(151a〜151d)及び第2連結部(152a〜152d)が撓むことにより、発光装置101を基台100に固定する際の回路基板1へのストレスを軽減することができる。 As described above, when the circuit board 1 is fixed to the base 100 with the spacer board 2 thinner than the thickness of the submount board 33 included in the COB board 3 arranged on the back surface of the circuit board 1, the protrusion of the circuit board 1 Stress is applied around the portions (12a to 12d). Therefore, in order to alleviate the stress generated on the circuit board 1 when the light emitting device 101 is fixed to the base 100, a part of the COB board 3 moves up and down to at least a part of a plurality of protrusions (12a to 12d). It is preferable that it is fixed as possible. As a configuration for that purpose, it is preferable to provide L-shaped slits (13a to 13d) between the plurality of protrusions (12a to 12d) and the circuit board 1. As shown in FIG. 3, by providing the L-shaped slits (13a to 13d), the protrusions (12a to 12d) are connected to the circuit board 1 by the first connecting portion (151a to 151d) and the second connecting portion (151a to 151d), respectively. It is connected by 152a to 152d). By bending the first connecting portions (151a to 151d) and the second connecting portions (152a to 152d), it is possible to reduce the stress on the circuit board 1 when fixing the light emitting device 101 to the base 100.

ここで、回路基板1及びスペーサ基板2を基台100に固定する際に、第1連結部(151a〜151d)及び第2連結部(152a〜152d)が撓むためには、回路基板1の第1開口部11の内側にCOB基板3が配置されることが好ましい。換言すれば、COB基板3と回路基板1の第1開口部11の周辺の枠体部分とは重ならないことが好ましい。さらに、第1連結部(151a〜151d)及び第2連結部(152a〜152d)が撓むためには、第1連結部(151a〜151d)及び第2連結部(152a〜152d)とCOB基板3とが重ならない領域が形成されていることが好ましい。図7(b)に示すように、発光装置101を基台100に固定したときに、第1連結部151a及び151bが撓む。その結果、回路基板1へのストレスを軽減することができる。 Here, when the circuit board 1 and the spacer board 2 are fixed to the base 100, in order for the first connecting portions (151a to 151d) and the second connecting portions (152a to 152d) to bend, the first of the circuit board 1 is used. It is preferable that the COB substrate 3 is arranged inside the opening 11. In other words, it is preferable that the COB substrate 3 and the frame portion around the first opening 11 of the circuit board 1 do not overlap. Further, in order for the first connecting portion (151a to 151d) and the second connecting portion (152a to 152d) to bend, the first connecting portion (151a to 151d), the second connecting portion (152a to 152d), and the COB substrate 3 are used. It is preferable that a region where the two do not overlap is formed. As shown in FIG. 7B, when the light emitting device 101 is fixed to the base 100, the first connecting portions 151a and 151b bend. As a result, the stress on the circuit board 1 can be reduced.

なお、本実施形態においては、回路基板1と突起部(12a〜12d)との間をそれぞれ第1連結部(151a〜151d)及び第2連結部(152a〜152d)の2か所で連結する例を示したが、このような例には限られず、1か所または3か所以上の連結部により連結するようにしてもよい。また、連結部の形状は、回路基板1の厚さや、スペーサ基板2と基台100との間の間隙の大きさ等を勘案して、決定するようにしてもよい。 In this embodiment, the circuit board 1 and the protrusions (12a to 12d) are connected at two locations, a first connecting portion (151a to 151d) and a second connecting portion (152a to 152d), respectively. Although an example is shown, the present invention is not limited to such an example, and the connection may be made by one or three or more connecting portions. Further, the shape of the connecting portion may be determined in consideration of the thickness of the circuit board 1, the size of the gap between the spacer substrate 2 and the base 100, and the like.

なお、発熱するCOB基板3とヒートシンク等の基台100との間に放熱効果を高めるために、熱伝導シートを配置してもよい。この場合は、COB基板3に含まれるサブマウント基板33の厚さと熱伝導シートの厚さとを合計した厚さよりも、スペーサ基板2の厚さを薄くするようにすることが好ましい。 A heat conductive sheet may be arranged between the heat-generating COB substrate 3 and the base 100 such as a heat sink to enhance the heat dissipation effect. In this case, it is preferable that the thickness of the spacer substrate 2 is thinner than the total thickness of the submount substrate 33 included in the COB substrate 3 and the thickness of the heat conductive sheet.

また、本実施形態による発光装置101全体の厚さは、回路基板1の厚さとスペーサ基板2の厚さを合計した厚さとなる。従って、COB基板3の発光部31から放射される光を遮る部品がないため、発光部31から放射される光を全て発光装置101から出射させることができる。 Further, the thickness of the entire light emitting device 101 according to the present embodiment is the sum of the thickness of the circuit board 1 and the thickness of the spacer board 2. Therefore, since there is no component that blocks the light emitted from the light emitting unit 31 of the COB substrate 3, all the light emitted from the light emitting unit 31 can be emitted from the light emitting device 101.

以上説明した本開示の実施形態に係る発光装置101においては、回路基板1上にコネクタ(41a,41b)のみを実装した例を示したが、このような例には限られない。例えば、サーマルシャットダウン回路等の回路部品を追加し、高機能な発光装置とするようにしてもよい。 In the light emitting device 101 according to the embodiment of the present disclosure described above, an example in which only the connectors (41a, 41b) are mounted on the circuit board 1 is shown, but the example is not limited to such an example. For example, a circuit component such as a thermal shutdown circuit may be added to make a high-performance light emitting device.
