Description

本発明は、LEDチップを用いた発光装置を備えた照明装置及びそれを用いた照明器具に関する。   The present invention relates to a lighting device including a light emitting device using an LED chip and a lighting fixture using the lighting device.

従来から、LEDチップとLEDチップから放射された光によって励起されてLEDチップとは異なる発光色の光を放射する波長変換材料(例えば、蛍光顔料、蛍光染料など)とを組み合わせてLEDチップの発光色とは異なる色合いの光を出す発光装置の研究開発が各所で行われている(例えば、特許文献1参照)。この種の発光装置としては、例えば、青色光あるいは紫外光を放射するLEDチップと蛍光体とを組み合わせて白色の光(白色光の発光スペクトル)を得る白色発光装置(一般的に白色LEDと呼ばれている)があり、このような白色発光装置を一般照明などのように比較的大きな光出力を必要とする用途に用いる場合、1つの白色発光装置では所望の光出力を得ることができないので、複数個の白色発光装置を1つの配線板上に搭載した照明装置を構成し、照明装置全体で所望の光出力を確保するようにするのが一般的である。   Conventionally, LED chips emit light by combining LED chips and wavelength conversion materials (for example, fluorescent pigments, fluorescent dyes, etc.) that are excited by light emitted from the LED chips and emit light of a different emission color from the LED chips. Research and development of light-emitting devices that emit light having a color different from that of color are being performed in various places (for example, see Patent Document 1). As this type of light-emitting device, for example, a white light-emitting device (generally called a white LED) that obtains white light (white light emission spectrum) by combining an LED chip that emits blue light or ultraviolet light and a phosphor. When such a white light emitting device is used for an application that requires a relatively large light output such as general illumination, a desired light output cannot be obtained with one white light emitting device. In general, an illuminating device in which a plurality of white light emitting devices are mounted on one wiring board is configured so that a desired light output is ensured in the entire illuminating device.

複数個の発光装置を1つの配線板上に搭載した照明装置では、各発光装置を点灯させた状態における個々の発光装置の発熱量は比較的少ないものの、発光装置の数の増加に伴って発熱量が多くなるので、配線板に熱が蓄積されやすく、照明装置全体の温度が上昇しやすい傾向にある。そこで、例えばアルミダイカスト製の放熱板から成る略箱体のボディの一端面に発光装置を熱結合して実装することで、発光装置が発する熱を効率よく放熱する照明装置が知られている。このような照明装置は、発光装置から放射される光を制御する配光部を有してボディを覆うように取り付けられるカバーを備え、カバーのボディとの対向面に突設された複数のピンをボディの前記一端面に貫設された取付孔に挿入して熱溶着することでカバーがボディの前記一端面に取り付けられるようになっている。
特開2005−158963号公報
In an illuminating device in which a plurality of light emitting devices are mounted on one wiring board, although the amount of heat generated by each light emitting device is relatively small when each light emitting device is lit, heat is generated as the number of light emitting devices increases. Since the amount increases, heat tends to accumulate on the wiring board, and the temperature of the entire lighting device tends to rise. Therefore, for example, there is known an illumination device that efficiently dissipates heat generated by a light emitting device by mounting the light emitting device on one end surface of a substantially box body made of a heat sink made of aluminum die casting. Such an illuminating device includes a cover that has a light distribution unit that controls light emitted from the light emitting device and is attached to cover the body, and a plurality of pins that protrude from the surface of the cover facing the body The cover is attached to the one end surface of the body by being inserted into an attachment hole penetrating the one end surface of the body and thermally welded.
JP 2005-158963 A

ところで、上記従来例では、カバーのピンの数及びボディの取付孔の数が少ないと外部からの力による応力がピンに集中し、カバーがボディから外れてしまう虞があった。そこで、ボディ及びカバーの取付強度を十分に確保するためにはカバーのピンの数及びボディの取付孔の数を増やす必要があった。しかしながら、ボディの取付孔の数を増やすとボディの前記一端面における発光装置の配置スペースが狭くなり、発光装置を構成する各部品間の絶縁距離を確保するのに十分な配置スペースを得るためには照明装置を大きく設計しなければならないという問題があった。   By the way, in the above conventional example, when the number of pins of the cover and the number of mounting holes of the body are small, there is a possibility that stress due to an external force concentrates on the pins and the cover is detached from the body. Therefore, in order to sufficiently secure the mounting strength of the body and the cover, it is necessary to increase the number of pins of the cover and the number of mounting holes of the body. However, when the number of mounting holes in the body is increased, the arrangement space for the light emitting device on the one end surface of the body is narrowed, and in order to obtain a sufficient arrangement space for securing the insulation distance between the components constituting the light emitting device. Had the problem that the lighting device had to be designed large.

本発明は、上記の点に鑑みて為されたもので、ボディ及びカバーの取付強度を確保し且つ装置を大型化することなく発光装置を構成する各部品間の絶縁距離を確保するのに十分な配置スペースを得ることのできる照明装置及び照明器具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 is sufficient to ensure the mounting strength of the body and the cover, and to ensure the insulation distance between the components constituting the light emitting device without increasing the size of the device. An object of the present invention is to provide a lighting device and a lighting fixture capable of obtaining a sufficient arrangement space.

請求項1の発明は、上記目的を達成するために、LEDチップを用いた一乃至複数の発光装置と、略箱体に形成されて一端面に発光装置が熱結合される形で実装されるボディと、ボディの前記一端面に取り付けられて発光装置から放射される光を制御する配光部を有するカバーとから成る照明装置であって、ボディ及びカバーには、熱溶着することで互いに固定される被固定部及び固定部がそれぞれ設けられ、カバーの外周縁には、ボディの外周縁に係止する係止部が設けられたことを特徴とする。   In order to achieve the above object, the invention of claim 1 is mounted in a form in which one or a plurality of light emitting devices using LED chips and a light emitting device are thermally coupled to one end surface formed in a substantially box shape. A lighting device comprising a body and a cover attached to the one end surface of the body and having a light distribution part for controlling light emitted from the light emitting device, and the body and the cover are fixed to each other by heat welding The fixed portion and the fixed portion to be fixed are provided, respectively, and a locking portion for locking to the outer peripheral edge of the body is provided on the outer peripheral edge of the cover.

請求項2の発明は、請求項1記載の照明装置と、照明装置を収納する器具本体とを備えたことを特徴とする。   According to a second aspect of the present invention, there is provided the lighting device according to the first aspect, and an appliance main body that houses the lighting device.

請求項1の発明によれば、カバーの外周縁に設けられた係止部によってカバーをボディの外周縁に係止することで、外部からの力によって固定部及び被固定部に加わる応力を低減することができるために固定部及び被固定部の数を少なくしてもボディ及びカバーの取付強度を確保することができ、したがって装置を大型化することなく発光装置を構成する各部品間の絶縁距離を確保するのに必要な配置スペースを得ることができる。   According to the first aspect of the present invention, the cover is locked to the outer peripheral edge of the body by the locking portion provided on the outer peripheral edge of the cover, thereby reducing the stress applied to the fixed portion and the fixed portion by an external force. Therefore, the mounting strength of the body and the cover can be ensured even if the number of the fixing parts and the fixed parts is reduced, so that the insulation between the components constituting the light emitting device can be achieved without increasing the size of the apparatus. An arrangement space necessary for securing the distance can be obtained.

請求項2の発明によれば、請求項1の効果を奏する照明装置を用いた照明器具を実現することができる。   According to invention of Claim 2, the lighting fixture using the illuminating device which has the effect of Claim 1 is realizable.

以下、本発明の実施形態の照明器具について図面を用いて説明する。本実施形態は、図1に示すように、略円柱状に形成され軸方向の一端面(図1における上面)に複数(本実施形態では4つ)の発光装置1が熱結合される形で実装されるボディ2と、ボディ2の前記一端面に取り付けられて発光装置1から放射される光を制御する配光部4を有するカバー3とから成る照明装置Aと、照明装置Aが取り付けられる器具本体5と、天井に取り付けられた取付器体(図示せず)に一端部が取り付けられて他端部に器具本体5が連結されるアーム6(図3(a)参照)とを備えている。尚、同図では後述する発光装置1の図示を省略している。   Hereinafter, the lighting fixture of embodiment of this invention is demonstrated using drawing. In the present embodiment, as shown in FIG. 1, a plurality of (four in this embodiment) light emitting devices 1 are thermally coupled to one axial end surface (upper surface in FIG. 1). A lighting device A including a body 2 to be mounted and a cover 3 having a light distribution unit 4 that is attached to the one end surface of the body 2 and controls light emitted from the light emitting device 1, and the lighting device A are attached. An instrument body 5 and an arm 6 (see FIG. 3 (a)) having one end attached to a fixture body (not shown) attached to the ceiling and connected to the other end are provided with the arm 6 (see FIG. 3A). Yes. In addition, illustration of the light-emitting device 1 mentioned later is abbreviate | omitted in the same figure.

発光装置1は、図2(b)に示すように、LEDチップ(図示せず)と、LEDチップの一表面側に実装された実装基板10と、実装基板10におけるLEDチップの実装面側でLEDチップを囲む枠体(図示せず)と、枠体の内側に透光性材料を充填して形成されてLEDチップを封止する封止部(図示せず)と、封止部に重ねて配置されるレンズ(図示せず)と、LEDチップから放射され封止部を透過した光によって励起されてLEDチップの発光色とは異なる色の光を放射する蛍光体を透明材料とともに成形した成形品であってレンズの光出射面側にレンズを覆い光出射面及び枠体との間に空気層が形成される形で配設されるドーム状の色変換部材11とから成る。   As shown in FIG. 2B, the light emitting device 1 includes an LED chip (not shown), a mounting substrate 10 mounted on one surface side of the LED chip, and a mounting surface side of the LED chip in the mounting substrate 10. A frame (not shown) surrounding the LED chip, a sealing part (not shown) that is formed by filling the inside of the frame with a light-transmitting material and seals the LED chip, and is superimposed on the sealing part And a lens (not shown) arranged with a transparent material that is excited by light emitted from the LED chip and transmitted through the sealing portion to emit light of a color different from the emission color of the LED chip together with a transparent material It is a molded product and comprises a dome-shaped color conversion member 11 that covers the lens on the light emitting surface side of the lens and is disposed in such a manner that an air layer is formed between the light emitting surface and the frame.

LEDチップは、青色光を放射するGaN系青色LEDチップから成り、色変換部材11は、シリコーン樹脂のような透光性材料とLEDチップから放射され封止部を透過した青色光によって励起されてブロードな黄色系の光を放射する粒子状の黄色蛍光体とを混合した混合物の成形品により構成されている。したがって、本実施形態における発光装置1は、LEDチップから放射された青色光と黄色蛍光体から放射された光とが色変換部材11の外面を通して放射されることとなり、白色光を得ることができる。尚、LEDチップの発光色は青色に限らず、例えばLEDチップとして紫外光LEDチップを用いる場合には、色変換部材11として例えば赤色蛍光体及び緑色蛍光体及び青色蛍光体を含有したものを用いて白色光を得るようにしても構わない。   The LED chip is composed of a GaN-based blue LED chip that emits blue light, and the color conversion member 11 is excited by a light-transmitting material such as a silicone resin and blue light emitted from the LED chip and transmitted through the sealing portion. It is composed of a molded product of a mixture obtained by mixing particulate yellow phosphors emitting broad yellow light. Therefore, in the light emitting device 1 in the present embodiment, the blue light emitted from the LED chip and the light emitted from the yellow phosphor are emitted through the outer surface of the color conversion member 11, and white light can be obtained. . Note that the emission color of the LED chip is not limited to blue. For example, when an ultraviolet LED chip is used as the LED chip, a color conversion member 11 containing, for example, a red phosphor, a green phosphor and a blue phosphor is used. Thus, white light may be obtained.

ボディ2は、アルミダイカスト製の放熱板であって、前記一端面の外周縁には、後述するブリッジ部52にねじ止めされる略矩形状の2つのねじ止め部21が図2(a)における上下両端部にそれぞれ突設されており、各ねじ止め部21には、それぞれ後述するブリッジ部52の雌ねじ部52aと重ね合わされて組立ねじ54が挿通される断面略円形状の挿通孔21aが厚み方向に貫設されている。また、ボディ2の前記一端面には、各ブリッジ部52aの内側近傍にそれぞれ断面略円形状の取付孔20が厚み方向に貫設されており、後述するカバー3のピン30が挿入される。また、ボディ2の前記一端面の略中央から図1における左側面にかけて後述する電線Bが挿通される略L字状の電線挿通部23が貫設されている。   The body 2 is a heat sink made of aluminum die casting, and two substantially rectangular screwing portions 21 screwed to a bridge portion 52 described later are provided on the outer peripheral edge of the one end surface in FIG. Each of the screwing portions 21 has an insertion hole 21a having a substantially circular cross section that is overlapped with a female screw portion 52a of a bridge portion 52 to be described later and into which an assembly screw 54 is inserted. It is penetrated in the direction. Further, on the one end face of the body 2, attachment holes 20 having a substantially circular cross section are provided in the thickness direction in the vicinity of the inside of each bridge portion 52a, and a pin 30 of the cover 3 to be described later is inserted. Further, a substantially L-shaped wire insertion portion 23 through which a later-described electric wire B is inserted extends from approximately the center of the one end surface of the body 2 to the left side surface in FIG.

取付孔20が設けられた部位は、ボディ2の他の部位と比べて薄肉に形成され、該部位の図1における下側は、厚み方向に窪んだ窪み部22となっている。而して、ピン30を取付孔20に挿入するとピン30の先端部が窪み部22に露出し、該ピン30の先端部をボディ2に対して熱溶着することで、カバー3がボディ2に取り付けられる(図2(c)参照)。   The part provided with the attachment hole 20 is formed thinner than the other part of the body 2, and the lower side of the part in FIG. 1 is a recessed part 22 that is recessed in the thickness direction. Thus, when the pin 30 is inserted into the mounting hole 20, the tip of the pin 30 is exposed to the recess 22, and the cover 3 is attached to the body 2 by heat-welding the tip of the pin 30 to the body 2. It is attached (see FIG. 2 (c)).

カバー3は、前記他端面を開口した有底円筒状に形成され、前記一端面には透光性材料から成る略椀状の4つの配光部4が設けられている(図1参照)。配光部4は、カバー3をボディ2に取り付けた状態において各々対応する発光装置1と対向するように配設され、各発光装置1から出射される光を配光制御する。カバー3の前記他端側の開口周縁には、ボディ2の各取付孔20とそれぞれ対向し且つ図1における下側に突出した棒状の一対のピン30が設けられている。   The cover 3 is formed in a bottomed cylindrical shape having an opening at the other end face, and four light distribution portions 4 each having a substantially bowl shape made of a translucent material are provided on the one end face (see FIG. 1). The light distribution unit 4 is disposed so as to face the corresponding light emitting device 1 in a state where the cover 3 is attached to the body 2, and controls light distribution from each light emitting device 1. A pair of rod-shaped pins 30 that are opposed to the mounting holes 20 of the body 2 and protrude downward in FIG.

ここにおいて、カバー3は前記他端側の開口面の内径が前記一端面の内径よりも長くなるように形成されており、カバー3の側面は図1における上側から下側にかけて外側に傾斜するようになっている。したがって、カバー3をボディ2に取り付ける際に、カバー3の外周縁が係止部31となってボディ2の外周縁の全周に亘って係止するので、照明装置に外部から力が加わったとしても、外部からの力による応力が分散されてピン30にかかる応力を低減することができる。   Here, the cover 3 is formed so that the inner diameter of the opening surface on the other end side is longer than the inner diameter of the one end surface, and the side surface of the cover 3 is inclined outward from the upper side to the lower side in FIG. It has become. Therefore, when the cover 3 is attached to the body 2, the outer peripheral edge of the cover 3 becomes the locking portion 31 and locks over the entire periphery of the outer peripheral edge of the body 2, so that force is applied to the lighting device from the outside. However, the stress applied to the pin 30 can be reduced by dispersing the stress due to the external force.

器具本体5は、アルミダイカスト製であり、図3(a)に示すように、有底円筒状に形成されて照明装置Aを収納する装置保持部50と、装置保持部50よりも大きい外径の円筒状に形成されて装置保持部50の外周を囲み且つ装置保持部50と同心的に配置される大径円筒部51と、装置保持部50と大径円筒部51とを所定の間隔を空けて連結する4つのブリッジ部52と、大径円筒部51外周の図3(a)における上側に取着されてアーム6が結合されるアーム結合部55とから成る。また、ブリッジ部52を除いた装置保持部50と大径円筒部51との間には、軸方向に貫通する4つの通気孔53が形成されており、該通気孔53を介して空気の流れる経路を形成することによって発光装置1で発生した熱を効率的に放熱させることができる。   The appliance body 5 is made of aluminum die-casting, and as shown in FIG. 3A, a device holding portion 50 that is formed in a bottomed cylindrical shape and houses the lighting device A, and an outer diameter larger than the device holding portion 50. A large-diameter cylindrical part 51 that is formed in a cylindrical shape and surrounds the outer periphery of the apparatus holding part 50 and is arranged concentrically with the apparatus holding part 50, and the apparatus holding part 50 and the large-diameter cylindrical part 51 are spaced apart from each other by a predetermined distance. It consists of four bridge portions 52 that are connected to each other and an arm coupling portion 55 that is attached to the upper side of the outer periphery of the large-diameter cylindrical portion 51 in FIG. In addition, four vent holes 53 penetrating in the axial direction are formed between the apparatus holding portion 50 excluding the bridge portion 52 and the large-diameter cylindrical portion 51, and air flows through the vent holes 53. By forming the path, the heat generated in the light emitting device 1 can be efficiently radiated.

ブリッジ部52は、図3(a)に示すように、装置保持部50と大径円筒部51と連続一体に形成されており、図3(a)における左右のブリッジ部52の略中央にはそれぞれ雌ねじ部52aが設けられている。而して、図3(b)に示すように、上記ブリッジ部52の図3(b)における上面にボディ2のねじ止め部21を載置し、組立ねじ54を挿通孔21aに挿通させて雌ねじ部52aでねじ止めすることで照明装置Aのボディ2が器具本体5に取付固定される。尚、カバー3側面には、ブリッジ部52及びねじ止め部21の近傍において組立ねじ54頭部の径よりも大きい径を有する凹部32が設けられている。このように組立ねじ54を避ける凹部32を設けることで、凹部32を設けない場合と比較して大径円筒部51の外径を小さくすることができ、したがって器具本体5の小型化を図れる。   As shown in FIG. 3A, the bridge portion 52 is formed integrally with the device holding portion 50 and the large-diameter cylindrical portion 51. In the center of the left and right bridge portions 52 in FIG. A female screw portion 52a is provided for each. Thus, as shown in FIG. 3B, the screwing portion 21 of the body 2 is placed on the upper surface of the bridge portion 52 in FIG. 3B, and the assembly screw 54 is inserted through the insertion hole 21a. The body 2 of the lighting device A is attached and fixed to the fixture body 5 by screwing with the female screw portion 52a. A recess 32 having a diameter larger than the diameter of the head of the assembly screw 54 is provided in the vicinity of the bridge portion 52 and the screwing portion 21 on the side surface of the cover 3. Thus, by providing the recessed part 32 which avoids the assembly screw 54, the outer diameter of the large diameter cylindrical part 51 can be made small compared with the case where the recessed part 32 is not provided, Therefore Size reduction of the instrument main body 5 can be achieved.

アーム結合部55は、図1に示すように、軸ねじ(図示せず)が挿通される軸受孔が貫設された軸受部55aと、別置の電源ユニット(図示せず)から導出された電線Bが挿通される切欠部55bとから成る。器具本体5は、軸受部55aの軸受孔とアーム6の図3(a)における下端部に設けられた軸受孔(図示せず)とを重ね合わせ、これら軸受孔に軸ねじを挿通してねじ止めすることで軸ねじを軸として回動自在にアーム6に結合される。また、電線Bがアーム6の内部空間及びアーム結合部55の切欠部55b及びボディ2の電線挿通孔23を通して発光装置1の実装基板10に設けられた給電用導体パターン(図示せず)と接続されることで、発光装置1に駆動電力が供給される。   As shown in FIG. 1, the arm coupling portion 55 is led out from a bearing portion 55a through which a bearing hole through which a shaft screw (not shown) is inserted and a separate power supply unit (not shown). It consists of a notch 55b through which the electric wire B is inserted. The instrument body 5 is formed by superimposing the bearing holes of the bearing portion 55a and the bearing holes (not shown) provided at the lower end portion of the arm 6 in FIG. 3A, and inserting shaft screws into these bearing holes. By being stopped, it is coupled to the arm 6 so as to be rotatable about a shaft screw. Further, the electric wire B is connected to a power supply conductor pattern (not shown) provided on the mounting substrate 10 of the light emitting device 1 through the internal space of the arm 6, the cutout portion 55 b of the arm coupling portion 55, and the electric wire insertion hole 23 of the body 2. As a result, driving power is supplied to the light emitting device 1.

上述のように、ボディ2にカバー3を固定する際に、カバー3の外周縁から成る係止部31がボディ2の外周縁全周に亘って係止するため、照明装置に外部から力が加わったとしても、外部からの力による応力が分散されてピン30にかかる応力を低減することができ、したがってピン30及び取付孔20の数を少なくしてもボディ2及びカバー3の取付強度を十分に確保することができる。また、ボディ2の前記一端面において、取付孔20の数を少なくすることができるために、照明装置を大型化することなく発光装置1を構成する各部品間の絶縁距離を確保するのに必要な配置スペースを得ることができる。   As described above, when the cover 3 is fixed to the body 2, the locking portion 31 formed by the outer peripheral edge of the cover 3 is locked over the entire outer peripheral edge of the body 2, so that a force is applied to the lighting device from the outside. Even if added, stress due to external force can be dispersed and the stress applied to the pin 30 can be reduced, so that the mounting strength of the body 2 and the cover 3 can be reduced even if the number of pins 30 and mounting holes 20 is reduced. It can be secured sufficiently. In addition, since the number of mounting holes 20 can be reduced on the one end surface of the body 2, it is necessary to secure an insulation distance between components constituting the light emitting device 1 without increasing the size of the lighting device. A large arrangement space can be obtained.
