従来から、発光素子を有する発光装置（照明ユニット）が提案されている（例えば、特許文献１）。   Conventionally, a light emitting device (illumination unit) having a light emitting element has been proposed (for example, Patent Document 1).

光学部材は、基板に配設された発光素子を覆うように設けられている。   The optical member is provided so as to cover the light emitting element disposed on the substrate.

また、従来から、発光素子を有する発光装置を用いた照明装置が提案されている（例えば、特許文献２）。   Conventionally, a lighting device using a light emitting device having a light emitting element has been proposed (for example, Patent Document 2).

特許文献２には、屋内および屋外で使用される照明装置の一例として、図１０に示す構成を有するＬＥＤランプ８１が記載されている。   Patent Document 2 describes an LED lamp 81 having the configuration shown in FIG. 10 as an example of an illumination device used indoors and outdoors.

ＬＥＤランプ８１は、ランプ本体８２、グローブ８３、Ｅ型の口金８４、点灯装置８５およびＣＯＢ（chip on board）型の発光装置８６を備えている。   The LED lamp 81 includes a lamp body 82, a globe 83, an E-type base 84, a lighting device 85, and a COB (chip on board) type light-emitting device 86.

ランプ本体８２は、金属材料で構成され、放熱部材としての機能を兼ね備えている。また、ランプ本体８２の支持面８２ａには、発光装置８６が取り付けられている。   The lamp body 82 is made of a metal material and has a function as a heat radiating member. A light emitting device 86 is attached to the support surface 82 a of the lamp body 82.

発光装置８６は、矩形状の基板８８を備えている（図１１参照）。この基板８８は、白色系のセラミックス材料で形成され、電気絶縁性を有している。また、基板８８は、一表面側（図１１では、上面側）の中央部に、配線パターン（図示せず）が形成された実装領域８８ａを有している。この実装領域８８ａには、複数の発光ダイオードチップ８９（図１０参照）が配置されている。なお、特許文献２には、各発光ダイオードチップ８９のプラス側電極およびマイナス側電極それぞれが、ボンディングワイヤ（図示せず）を介して上記配線パターンと電気的に接続されていることが記載されている。また、特許文献２には、上記配線パターンおよび各発光ダイオードチップ８９が、封止材９０で覆われていることが記載されている。   The light emitting device 86 includes a rectangular substrate 88 (see FIG. 11). The substrate 88 is made of a white ceramic material and has electrical insulation. In addition, the substrate 88 has a mounting region 88a in which a wiring pattern (not shown) is formed in the central portion on one surface side (the upper surface side in FIG. 11). A plurality of light emitting diode chips 89 (see FIG. 10) are arranged in the mounting region 88a. In Patent Document 2, it is described that the positive electrode and the negative electrode of each light-emitting diode chip 89 are electrically connected to the wiring pattern via bonding wires (not shown). Yes. Patent Document 2 describes that the wiring pattern and each light-emitting diode chip 89 are covered with a sealing material 90.

また、ランプ本体８２の支持面８２ａには、一対の押圧部材９１，９２が、ねじ９３により取り付けられている。各押圧部材９１，９２の各々は、ステンレス鋼板を階段状に折り曲げた板ばねにより構成されている。また、各押圧部材９１，９２の各々は、固定部９１ａ，９２ａ、起立部９１ｂ，９２ｂおよび押圧部９１ｃ，９２ｃを有している（図１１参照）。ここで、特許文献２には、各押圧部材９１，９２の押圧部９１ｃ，９２ｃの各々が、基板８８の周部（実装領域８８ａ以外の部位）に、配置される旨が記載されている。また、特許文献２には、各押圧部材９１，９２の押圧部９１ｃ，９２ｃの各々が、ランプ本体８２の支持面８２ａに向かって発光装置８６を弾性的に押圧する旨が記載されている。   A pair of pressing members 91 and 92 are attached to the support surface 82 a of the lamp body 82 by screws 93.

ところで、特許文献１に開示された照明ユニットでは、光学部材が、基板に配設された発光素子を覆うように設けられているので、発光素子から発光される光の配光を調整することが可能となる。   By the way, in the illumination unit disclosed in Patent Document 1, since the optical member is provided so as to cover the light emitting element disposed on the substrate, the light distribution of the light emitted from the light emitting element can be adjusted. It becomes possible.

しかしながら、特許文献１に開示された照明ユニットでは、基板を、ねじにより放熱ケース部材に装着しているので、例えば、基板の材料として、セラミック材料を用いた場合に、基板が割れてしまう可能性がある。   However, in the lighting unit disclosed in Patent Document 1, since the substrate is attached to the heat radiating case member with screws, for example, when a ceramic material is used as the material of the substrate, the substrate may be broken. There is.

また、特許文献２に開示されたＬＥＤランプ８１では、各押圧部材９１，９２の押圧部９１ｃ，９２ｃの各々が、ランプ本体８２の支持面８２ａに向かって発光装置８６の基板８８を弾性的に押圧するので、基板８８に応力が生じ難くなり、基板８８の割れを防止することが可能となる。   In the LED lamp 81 disclosed in Patent Document 2, each of the pressing portions 91 c and 92 c of the pressing members 91 and 92 elastically pushes the substrate 88 of the light emitting device 86 toward the support surface 82 a of the lamp body 82. Since the pressing is performed, it is difficult for the substrate 88 to be stressed, and it is possible to prevent the substrate 88 from cracking.

しかしながら、特許文献１に開示されたＬＥＤランプ８１では、ステンレス鋼板の板ばねにより構成された各押圧部材９１，９２の各々が、ねじ９３を用いて金属製のランプ本体８２に取り付けられている。そのため、このＬＥＤランプ８１では、基板８８の充電部（上記配線パターン）の絶縁性能を高めようとすると、各押圧部９１ｃ，９２ｃと、封止材９０により覆われた上記配線パターンおよび各発光ダイオードチップ８９との間の沿面距離が長くなり、基板８８の平面サイズが大きくなるという懸念がある。   However, in the LED lamp 81 disclosed in Patent Document 1, each of the pressing members 91 and 92 formed of a stainless steel plate spring is attached to a metal lamp body 82 using a screw 93. Therefore, in this LED lamp 81, in order to improve the insulation performance of the charging portion (the wiring pattern) of the substrate 88, the wiring patterns and the light emitting diodes covered with the pressing portions 91c and 92c and the sealing material 90 are used. There is a concern that the creepage distance to the chip 89 is increased, and the planar size of the substrate 88 is increased.

本発明は上記事由に鑑みて為されたものであり、その目的は、所望の配光を得ることが可能で、且つ、実装基板の平面サイズを大きくすることなく、実装基板の充電部の絶縁性能を高めることが可能な発光装置およびそれを用いた照明器具を提供することにある。   The present invention has been made in view of the above reasons, and its purpose is to obtain a desired light distribution and to insulate a charging part of the mounting board without increasing the plane size of the mounting board.

以下、本実施形態の発光装置について、図１〜図８を参照しながら説明する。   Hereinafter, the light-emitting device of this embodiment will be described with reference to FIGS.

本実施形態の発光装置１０は、例えば、照明器具３０（図８参照）の光源として用いることができる。発光装置１０は、放熱部材１と、ＬＥＤ（図示せず）が実装される実装基板２ｂと、実装基板２ｂの側部および一表面（図１では、上面）の周部を覆う絶縁カバー３と、実装基板２ｂを、絶縁カバー３を介して放熱部材１側に押圧する押圧部材４とを備えている。また、発光装置１０は、ＬＥＤから放射された光の配光を制御するレンズ部４０を備えている。   The light-emitting device 10 of this embodiment can be used as a light source of the lighting fixture 30 (refer FIG. 8), for example. The light emitting device 10 includes a heat dissipating member 1, a mounting substrate 2b on which an LED (not shown) is mounted, an insulating cover 3 that covers a side portion of the mounting substrate 2b and a peripheral portion of one surface (the upper surface in FIG. 1). And a pressing member 4 that presses the mounting substrate 2b toward the heat radiating member 1 via the insulating cover 3. In addition, the light emitting device 10 includes a lens unit 40 that controls the light distribution of the light emitted from the LEDs.

放熱部材１は、板状（本実施形態では、略矩形板状）に形成されている。この放熱部材１は、樹脂に比べて熱伝導率が高い材料（例えば、アルミニウム、銅、ステンレスなどの金属材料）により形成することができる。   The heat radiating member 1 is formed in a plate shape (in the present embodiment, a substantially rectangular plate shape). The heat radiating member 1 can be formed of a material (for example, a metal material such as aluminum, copper, and stainless steel) having a higher thermal conductivity than the resin.

実装基板２ｂは、例えば、白色系のセラミック材料（例えば、酸化アルミニウム、窒化アルミニウムなど）により形成された電気絶縁性を有するセラミック基板である。また、実装基板２ｂには、ＬＥＤに電気的に接続可能な導体パターン（図示せず）が設けられている。なお、本実施形態の発光装置１０では、実装基板２ｂの外周形状を、矩形状に形成しているが、この形状を特に限定するものではない。また、本実施形態では、実装基板２ｂとして、セラミック基板を用いているが、これに限らず、例えば、ガラスエポキシ樹脂などからなる絶縁性基材により形成されたプリント配線板などを用いてもよい。   The mounting substrate 2b is an electrically insulating ceramic substrate formed of, for example, a white ceramic material (for example, aluminum oxide, aluminum nitride, etc.). The mounting board 2b is provided with a conductor pattern (not shown) that can be electrically connected to the LED. In the light emitting device 10 of this embodiment, the outer peripheral shape of the mounting substrate 2b is formed in a rectangular shape, but this shape is not particularly limited. In this embodiment, a ceramic substrate is used as the mounting substrate 2b. However, the present invention is not limited to this, and for example, a printed wiring board formed of an insulating base material made of glass epoxy resin or the like may be used. .

実装基板２ｂの上記一表面側の中央部には、１つないし複数のＬＥＤが実装されている。   One or more LEDs are mounted on the central portion of the mounting substrate 2b on the one surface side.

ＬＥＤとしては、例えば、青色光を放射するＬＥＤチップ（以下、青色ＬＥＤチップと称する）と、青色ＬＥＤチップから放射された青色光により励起されブロードな黄色光を放射する黄色蛍光体からなる蛍光体とを組み合わせて白色光を得る白色ＬＥＤを用いることができる。このような白色ＬＥＤは、青色ＬＥＤチップを覆い黄色蛍光体を含有した第１の透光性材料からなる色変換部（図示せず）を有している。第１の透光性材料としては、例えば、シリコーン樹脂、エポキシ樹脂、ガラスなどを採用することができる。   As the LED, for example, a phosphor composed of an LED chip that emits blue light (hereinafter referred to as a blue LED chip) and a yellow phosphor that emits broad yellow light that is excited by the blue light emitted from the blue LED chip. Can be used to obtain white light. Such a white LED has a color conversion part (not shown) made of a first light-transmitting material that covers a blue LED chip and contains a yellow phosphor. As the first light transmissive material, for example, a silicone resin, an epoxy resin, glass, or the like can be employed.

本実施形態の発光装置１０では、第２の透光性材料からなる封止部２ａが、青色ＬＥＤチップおよび上記色変換部を封止している。第２の透光性材料としては、例えば、シリコーン樹脂、エポキシ樹脂、ガラスなどを採用することができる。また、本実施形態では、封止部２ａの外周形状を、矩形状としているが、この形状を特に限定するものではなく、例えば、円形状、楕円形状などであってもよい。   In the light emitting device 10 of the present embodiment, the sealing portion 2a made of the second light transmissive material seals the blue LED chip and the color conversion portion.

In short, it is preferable that the mounting portions 43 are arranged on different sides across the major axis in the minor axis direction of the lens unit 40 in plan view. Thereby, in the light-emitting device 10 of this embodiment, since the planar view shape of the lens part 40 is made into the ellipse shape, it becomes possible to make the dimension of the long axis direction of the lens part 40 in the thermal radiation member 1 small, and size reduction.

In short, in the light emitting device 10 of the present embodiment, the mounting substrate 2b is disposed on the one surface side of the heat radiating member 1 (the front end surface 1e side of the protruding portion 1c of the heat radiating member 1). Here, the planar size of the mounting substrate 2b is such that when the side portion of the mounting substrate 2b and the peripheral portion of the one surface are covered with the insulating cover 3, the side portion of the mounting substrate 2b is the side wall portion 3b of the insulating cover 3 and the partition wall. It is set to abut against the portion 13. Thereby, in the light-emitting device 10 of this embodiment, it becomes possible to control that the mounting substrate 2b moves to the side. Moreover, in this embodiment, although the planar size of the protrusion part 1c of the heat radiating member 1 is set smaller than the planar size of the mounting substrate 2b, it may be set to the same size as the planar size of the mounting substrate 2b. Good. Thereby, in the light-emitting device 10 of this embodiment, it becomes possible to efficiently conduct the heat generated by the LEDs of the light source unit 2 to the heat radiating member 1.

ここにおいて、絶縁カバー３の各鍔部３ｄの突出寸法は、放熱部材１の突台部１ｃの側面と、放熱部材１の第２の凹所１ｂの内側面との間の距離よりも小さく設定されている（図１参照）。また、各鍔部３ｄの厚み寸法は、突台部１ｃの突出寸法よりも小さく設定されている（図１参照）。また、絶縁カバー３の蓋部３ａの周部は、上記直交する方向の両端部（図４では、左上端部および右下端部）の各々に、放熱部材１側（図４では、下側）へ突出する凸部３ｅ（図１参照）が設けられている。各凸部３ｅは、放熱部材１の突台部１ｃとで実装基板２ｂを挟持する。   Here, the projecting dimension of each flange 3d of the insulating cover 3 is set to be smaller than the distance between the side surface of the projecting portion 1c of the heat radiating member 1 and the inner side surface of the second recess 1b of the heat radiating member 1. (See FIG. 1). Moreover, the thickness dimension of each collar part 3d is set smaller than the protrusion dimension of the protrusion part 1c (refer FIG. 1). Further, the peripheral portion of the lid portion 3a of the insulating cover 3 is disposed on each of the end portions in the orthogonal direction (the upper left end portion and the lower right end portion in FIG. 4) on the heat radiating member 1 side (the lower side in FIG. 4). Convex part 3e (refer to Drawing 1) which protrudes to is provided. Each convex portion 3 e sandwiches the mounting substrate 2 b with the protruding portion 1 c of the heat radiating member 1.

また、押圧部材４の各突出部４ｅ，４ｆの突出寸法は、押圧部材４が放熱部材１に固定されたときに、絶縁カバー３の側壁部３ｂの外側と接触可能な寸法に設定されている（図１参照）。これにより、本実施形態の発光装置１０では、各突出部４ｅ，４ｆの各々が、絶縁カバー３が実装基板２ｂの側方へ移動するのを規制する。   The projecting dimensions of the projecting parts 4 e and 4 f of the pressing member 4 are set to dimensions that allow contact with the outside of the side wall part 3 b of the insulating cover 3 when the pressing member 4 is fixed to the heat radiating member 1.
