Description

本発明は、主として発光ダイオード(Light Emitting Diode、以下LEDと称する)を光源として用いた発光装置に関する。   The present invention mainly relates to a light emitting device using a light emitting diode (hereinafter referred to as LED) as a light source.

上記のような、LEDを光源とした発光装置は、近年あらゆる分野において使用されており、例えば、液晶表示装置用のバックライト装置、高い輝度が要求される自動車のヘッドライトやストップランプ、信号灯、または屋外用大型ディスプレイ等の用途への応用が進められている。このような発光装置では、配線基板の表面に複数のLEDが実装されており、LEDはその配線基板を介して電気的に接続されているものが周知となっている(例えば、特許文献1を参照)。   Light emitting devices using LEDs as light sources as described above have been used in various fields in recent years. For example, backlight devices for liquid crystal display devices, automobile headlights and stop lamps, signal lights, which require high brightness, Or the application to uses, such as an outdoor large-sized display, is advanced. In such a light emitting device, it is well known that a plurality of LEDs are mounted on the surface of a wiring board, and the LEDs are electrically connected via the wiring board (for example, see Patent Document 1). reference).

しかしながら、上記のように配線基板の表面にLED及びコネクタを実装する発光装置では、その部品点数が多く実装工数がかかるという問題があった。また、配線基板の大きさや形状が変更されたときには、実装したLED及びコネクタの取り外しが困難なためこれらの部品を再利用することが困難となっている問題もあった。そこで、これらの問題を解決するため、例えば図12に示すような発光装置100が開発されている。この発光装置100は、LEDが実装された発光部101がそれぞれのケーブル103の先端部分に設けられ、外部コネクタ105、ワイヤーハーネス102、及びケーブル103を介して発光部101に電力が供給され、発光部101のLEDが発光する構成となっている。   However, in the light emitting device in which the LED and the connector are mounted on the surface of the wiring board as described above, there is a problem that the number of parts is large and the mounting man-hour is required. In addition, when the size or shape of the wiring board is changed, there is a problem that it is difficult to reuse these components because it is difficult to remove the mounted LED and connector. In order to solve these problems, for example, a light emitting device 100 as shown in FIG. 12 has been developed. In the light emitting device 100, a light emitting unit 101 on which an LED is mounted is provided at the distal end portion of each cable 103, and power is supplied to the light emitting unit 101 via the external connector 105, the wire harness 102, and the cable 103 to emit light. The LED of the unit 101 emits light.

上記のように構成される発光装置100は、発光部101がケーブル103の先端に直接実装されているため、それぞれの発光部101を支持する支持部材さえあればよく従来の回路基板が不要になる。また、支持部材等からの発光部101の取り外しが容易になるため、部品の再利用も容易に行うことが可能となり上述した問題を解決している。しかしながら、図12のような発光装置100を用いる場合、それぞれの発光部101に対してケーブル103を配線する必要があるため、ケーブル自体の絶対量が多くなり、ケーブル等の信号線が大量に必要になるという課題があった。   In the light emitting device 100 configured as described above, since the light emitting unit 101 is directly mounted on the tip of the cable 103, it is only necessary to have a support member for supporting each light emitting unit 101, and a conventional circuit board is not necessary. . In addition, since the light emitting unit 101 can be easily detached from the support member or the like, the components can be easily reused, and the above-described problems are solved. However, when the light emitting device 100 as shown in FIG. 12 is used, it is necessary to wire the cables 103 to the respective light emitting units 101. Therefore, the absolute amount of the cables themselves is increased, and a large number of signal lines such as cables are required. There was a problem of becoming.

In a light-emitting device including a first light-emitting unit 10 and a second light-emitting unit 30) and a light-emitting unit in which a connection terminal unit (for example, the LED terminal 51 in the embodiment) is electrically connected to a contact and attached on a main body The housing is provided with a first connector portion and a second connector portion formed by exposing the contact portion of the contact so that a mating connector having a terminal made of a conductive material can be fitted to the first and second connector portions. When the mating connector is fitted to at least one of the first and second connector portions, the contact and the terminal of the mating connector are electrically connected, and the terminal is connected to the connector. The power supply for causing the light emitting part to emit light to the connection terminal part via the tact is configured, and when the mating connector is fitted to both the first and second connector parts, the mating part fitted to the first connector part The terminal of the connector, the contact, and the terminal of the mating connector fitted to the second connector portion are configured to be electrically connected.

なお、以下の説明では便宜上、各図において矢印「上下、前後、左右」で示すように、図1の支持部材60の延びる面に対して直交する方向を上下方向とし、支持部材60の面内において前後および左右を図に矢印で示す方向で規定する。具体的には、支持部材60の表面に実装される発光装置1が存在する方向(図1及び図2の紙面の上方向)を上方向、その反対方向を下方向、この上下方向に直角な面内において、後に詳述する電気ケーブル70が延びる方向を前後方向、前後方向に直角な方向を左右方向と定義して説明するが、あくまで説明の都合上での定義であり、これが各部材の取付方向、使用方向を規定するものではない。   In the following description, for the sake of convenience, as indicated by arrows “up / down, front / rear, left / right” in each figure, the direction perpendicular to the surface of the support member 60 in FIG. The front and rear and the left and right are defined in the direction indicated by the arrows in the figure. Specifically, the direction in which the light-emitting device 1 mounted on the surface of the support member 60 is present (upward on the paper surface in FIGS. 1 and 2) is upward, the opposite direction is downward, and the direction perpendicular to the vertical direction is perpendicular. In the plane, the direction in which the electric cable 70, which will be described in detail later, is defined as the front-rear direction, and the direction perpendicular to the front-rear direction is defined as the left-right direction, but this is a definition for convenience of explanation, and this is the definition of each member. It does not stipulate the mounting direction or usage direction.

発光装置1は、図1〜図5に示すように、後述する発光部52を有するLED光源50と、LED光源50が上面に実装される第1本体部10と、第1本体部10を下方から嵌合可能に構成されるとともに支持部材60に固定支持される第2本体部30とを備えて構成される。まずは、第1本体部10の後述するLED実装部20bに実装されるLED光源50について説明する。LED光源50は、図4及び図5に示すようにLEDハウジング53に、前後3本ずつで合計6つ設けられるLED端子51と、3個の発光部52とを備えて構成される。発光部52は、青色発光部52b、赤色発光部52r、及び緑色発光部52gからなる。LED端子51は、それぞれ左右対になって発光部52b,52r,52gに対応して設けられており、第1本体部10の6本のコンタクト20のLED実装部20b(後に詳述)に半田接合されて実装されている。   As shown in FIGS. 1 to 5, the light emitting device 1 includes an LED light source 50 having a light emitting unit 52 to be described later, a first main body 10 on which the LED light source 50 is mounted, and a first main body 10 downward. And a second main body portion 30 that is fixedly supported by the support member 60 and is configured to be fitted. First, the LED light source 50 mounted on the LED mounting unit 20b described later of the first main body unit 10 will be described. As shown in FIGS. 4 and 5, the LED light source 50 includes a LED housing 53 including six LED terminals 51 provided in total, three front and rear, and three light emitting units 52. The light emitting unit 52 includes a blue light emitting unit 52b, a red light emitting unit 52r, and a green light emitting unit 52g. The LED terminals 51 are provided in left and right pairs so as to correspond to the light emitting portions 52b, 52r, and 52g, and are soldered to the LED mounting portions 20b (detailed later) of the six contacts 20 of the first main body portion 10. Bonded and mounted.

次に、図6〜図8を参照して第1本体部10について説明する。第1本体部10は、例えばインサートモールドにより製造され、絶縁材料樹脂製のハウジング11内に6個のコンタクト20を整列保持して構成される。より具体的には、図6〜図8から分かるように、ハウジング11内に、3個ずつのコンタクト20を左右に整列させてそれらが前後に対となって対称となるように保持して構成される。   Next, the first main body 10 will be described with reference to FIGS. The first main body 10 is manufactured by, for example, insert molding, and is configured by aligning and holding six contacts 20 in a housing 11 made of an insulating material resin. More specifically, as can be seen from FIGS. 6 to 8, three contacts 20 are arranged in the housing 11 in the left and right direction and are held so as to be symmetrical in pairs in the front and rear. Is done.

ハウジング11は、上面が略円形状となり上部が略円柱状に形成され、底面が略正方形状となり下部が略直方体状に形成されて構成される。また、ハウジング11は、下方に開口して形成される第1コネクタ部12及び第2コネクタ部13を前後一対に有し、第1コネクタ部12及び第2コネクタ部13の内部には、コンタクト20の接触部20d(後に詳述)が下方に延びて形成される。また、第1コネクタ部12及び第2コネクタ部13の開口部は後述する相手コネクタ80の嵌合突起部83よりも若干大きい程度となっており、第1コネクタ部12及び第2コネクタ部13の空間の形状は略直方体となっており、相手コネクタ80の嵌合突起部83を嵌合接続可能に構成される(後に詳述)。   The housing 11 is configured such that the upper surface is substantially circular and the upper portion is formed in a substantially cylindrical shape, the bottom surface is formed in a substantially square shape, and the lower portion is formed in a substantially rectangular parallelepiped shape. The housing 11 has a pair of front and rear first and second connector portions 12 and 13 formed to open downward. Contacts 20 are provided inside the first and second connector portions 12 and 13. The contact portion 20d (described in detail later) extends downward. Moreover, the opening part of the 1st connector part 12 and the 2nd connector part 13 is a grade slightly larger than the fitting protrusion part 83 of the other party connector 80 mentioned later, and the 1st connector part 12 and the 2nd connector part 13 of FIG. The shape of the space is a substantially rectangular parallelepiped, and is configured so that the fitting protrusion 83 of the mating connector 80 can be fitted and connected (detailed later).

ハウジング11は、図8に示すように第1コネクタ部12及び第2コネクタ部13を前後左右から挟むようにしてコンタクト20を固定保持する。上述のように6個のコンタクト20はそれぞれ導電材料製の金属材を折り曲げ成形されて製造され、露出部20a、LED実装部20b、屈曲部20c、及び接触部20dが一体に繋がって作られている。それぞれ前後方向の最も外側に位置する露出部20aは、左右に3本ずつ並んで前方に3箇所、後方に3箇所、それぞれ前後端部が外方に露出して設けられている。   As shown in FIG. 8, the housing 11 fixes and holds the contact 20 so as to sandwich the first connector portion 12 and the second connector portion 13 from front, rear, left and right. As described above, each of the six contacts 20 is manufactured by bending a metal material made of a conductive material, and the exposed portion 20a, the LED mounting portion 20b, the bent portion 20c, and the contact portion 20d are integrally connected. Yes. The exposed portions 20a located on the outermost sides in the front-rear direction are respectively provided with three on the left and right sides, three at the front and three at the rear, with the front and rear ends exposed to the outside.

露出部20aの内側部は上方にクランク状に折れ曲がってLED実装部20bに一体に繋がる。露出部20aを設け、コンタクト20の一部を外方に露出させることによりこの部分から熱を放出させることができるので、LED実装部20bの上面に実装されたLED光源50を、コンタクト20を介して冷却させることができ、LED光源50の温度が上昇して寿命が短くなる問題の発生を抑えることができる。LED実装部20bは上面が上方に露出した状態でハウジング11に保持されており、LED実装部20bの上面に、後述するLED光源50のそれぞれのLED端子51が表面実装(半田接合)される。そして、LED実装部20bの内端に一体に繋がってクランク状に折れ曲がる屈曲部20cが、ハウジング11に埋め込まれるようにして固定保持されており、屈曲部20cの下端から下方に棒状に延びて接触部20dが一体に繋がって設けられる。   The inner portion of the exposed portion 20a is bent upward in a crank shape and integrally connected to the LED mounting portion 20b. Since the exposed portion 20a is provided and a part of the contact 20 is exposed to the outside, heat can be released from this portion. Therefore, the LED light source 50 mounted on the upper surface of the LED mounting portion 20b is connected via the contact 20. The temperature of the LED light source 50 rises and the problem of shortening the life can be suppressed. The LED mounting portion 20b is held by the housing 11 with the upper surface exposed upward, and each LED terminal 51 of the LED light source 50 described later is surface-mounted (soldered) on the upper surface of the LED mounting portion 20b. A bent portion 20c that is integrally connected to the inner end of the LED mounting portion 20b and bends in a crank shape is fixed and held so as to be embedded in the housing 11, and extends downward in a bar shape from the lower end of the bent portion 20c.

以上、本実施形態における発光装置1においては、図1及び図2に示すように第2本体部30を支持部材60に固定支持させ、第1本体部10を第2本体部30に嵌合接続させ、相手コネクタ80を第1本体部10に嵌合接続させることが可能となっている。以下で、これらの固定支持及び嵌合接続の方法及び作用について説明する。まずは、第2本体部30を支持部材60に固定支持させる方法及び作用について説明する。   As described above, in the light emitting device 1 according to the present embodiment, as shown in FIGS. 1 and 2, the second main body 30 is fixedly supported by the support member 60, and the first main body 10 is fitted and connected to the second main body 30. Thus, the mating connector 80 can be fitted and connected to the first main body 10. Below, the method and effect | action of these fixed support and fitting connection are demonstrated. First, a method and operation for fixing and supporting the second main body 30 to the support member 60 will be described.

まず、支持部材60の支持孔61(図1及び図2参照)の下方に第2本体部30を位置させるとともに、左側突起部34の位置が支持孔61の左方に形成された左凹部62の真下に位置するようにして、第2本体部30の支持部材60に対する前後左右方向の位置合わせを行う。位置合わせをした後第2本体部30を上方に移動させると、左凹部62に左側突起部34が嵌合され始めるとともに、図9に示す4つの上嵌合突起部32の突出部36の上方に形成されたテーパ面36aが支持孔61の周縁部に当接接触する。   First, the second main body 30 is positioned below the support hole 61 (see FIGS. 1 and 2) of the support member 60, and the left recess 62 is formed with the left protrusion 34 formed on the left side of the support hole 61. The second main body 30 is aligned in the front-rear and left-right directions with respect to the support member 60 so that the second main-body unit 30 is positioned directly below. When the second main body 30 is moved upward after the alignment, the left protrusion 34 starts to be fitted into the left recess 62 and above the protrusions 36 of the four upper fitting protrusions 32 shown in FIG. The tapered surface 36 a formed in contact with the peripheral edge of the support hole 61 comes into contact with the peripheral edge of the support hole 61.

そして更に、第2本体部30を上方に移動させると、4つの上嵌合突起部32が内側に撓み支持孔61に嵌入し、突出部36が支持孔61の周縁部を上動し、突出部36が支持孔61を乗り越えた時点で上嵌合突起部32の弾性変形が元に戻り、図3(a)及び図5に示すように、4つの突出部36が支持部材60の上面の支持孔61の周縁部分を覆うように位置する。この結果、支持部材60の上面と4つの突出部36の下面とが対向し突出部36の下面と第2本体部30の直方体部分の上面により支持部材60が上下から挟み込まれた状態となり、第2本体部30が支持孔61に嵌合した状態で支持部材60に固定支持されることができる。なお、4つの上嵌合突起部32を内側に撓ませ、4つの突出部36と支持部材60との係合を解除した状態で、第2本体部30を支持孔61から引き下げることにより、第2本体部30を支持部材60から外すことができる。   Further, when the second main body 30 is moved upward, the four upper fitting protrusions 32 bend inwardly and fit into the support holes 61, and the protrusions 36 move up the peripheral edge of the support holes 61 to protrude. When the portion 36 gets over the support hole 61, the elastic deformation of the upper fitting protrusion 32 returns to its original state, and the four protruding portions 36 are formed on the upper surface of the support member 60 as shown in FIGS. It is located so that the peripheral part of the support hole 61 may be covered. As a result, the upper surface of the support member 60 and the lower surfaces of the four projecting portions 36 face each other, and the support member 60 is sandwiched from above and below by the lower surface of the projecting portion 36 and the upper surface of the rectangular parallelepiped portion of the second main body portion 30. 2 The main body 30 can be fixedly supported by the support member 60 in a state in which the main body 30 is fitted in the support hole 61. In addition, by bending the four upper fitting protrusions 32 inward and releasing the engagement between the four protrusions 36 and the support member 60, the second main body 30 is pulled down from the support hole 61, thereby 2 The main body 30 can be removed from the support member 60.

次に、第1本体部10を上記第2本体部30に嵌合させる方法及び作用について説明する。まず、図1及び図2に示すように第1本体部10の左溝部17が第2本体部30の左側突起部34の真下に位置するようにして第1本体部10の第2本体部30に対する前後左右方向の位置合わせを行う。その位置合わせをした状態で、第1本体部10を第2本体部30に向かって上方に移動させると、左溝部17が左側突起部34に嵌合され始めるとともに、図9(b)に示す第2本体部30の4つの下嵌合突起部33の突出部37の下方に形成されたテーパ面37aに第1本体部10の左右側面に形成されたテーパ面14a及び15a(図6参照)が当接接触する。   Next, a method and operation for fitting the first main body 10 to the second main body 30 will be described. First, as shown in FIGS. 1 and 2, the second body portion 30 of the first body portion 10 is arranged such that the left groove portion 17 of the first body portion 10 is positioned directly below the left protrusion 34 of the second body portion 30. Align the front, rear, left and right. When the first main body portion 10 is moved upward toward the second main body portion 30 in the aligned state, the left groove portion 17 starts to be fitted to the left protrusion 34 and is shown in FIG. 9B. Tapered surfaces 14a and 15a formed on the left and right side surfaces of the first main body 10 on the tapered surfaces 37a formed below the protrusions 37 of the four lower fitting protrusions 33 of the second main body 30 (see FIG. 6). Makes contact.

そして更に、第1本体部10を上方に移動させると、下嵌合突起部33が左右外側に撓み、第1本体部10の円柱部分が第2本体部30の嵌合孔31に嵌入し第1本体部10の左右の被係合部14,15が第2本体部30の突出部37に対して上動し、左右のテーパ面14a,15aの下部の左右の側面14b,15bが突出部37を乗り越えた時点で下嵌合突起部33の弾性変形が元に戻り、図3(b)に示すように、4つの突出部37が左右の被係合面14c,15cを下方から覆うように位置する(図3(b)は右被係合面15cのみを図示)。この結果、左右の被係合面14c,15cと4つの下嵌合突起部33の突出部37の上面とが対向し、第1本体部10が第2本体部30に嵌合した状態のまま係止保持され嵌合が外れない状態となる。なお、4つの下嵌合突起部33を左右外側に撓ませ4つの突出部37と左被係合面14c及び右被係合面15cとの係合を解除した状態で、第1本体部10を第2本体部30から引き下げることにより、第1本体部10を第2本体部30から外すことができる。   Further, when the first main body 10 is moved upward, the lower fitting protrusion 33 bends to the left and right, and the cylindrical portion of the first main body 10 fits into the fitting hole 31 of the second main body 30 and the second 1 The left and right engaged parts 14 and 15 of the main body part 10 move upward relative to the protruding part 37 of the second main body part 30, and the left and right side surfaces 14b and 15b below the left and right tapered surfaces 14a and 15a are protruding parts. The elastic deformation of the lower fitting protrusion 33 returns to the original state when the vehicle 37 is overcome, and the four protrusions 37 cover the left and right engaged surfaces 14c and 15c from below as shown in FIG. (FIG. 3B shows only the right engaged surface 15c). As a result, the left and right engaged surfaces 14c and 15c and the upper surfaces of the protrusions 37 of the four lower fitting protrusions 33 face each other, and the first main body portion 10 remains in a state of being fitted to the second main body portion 30. It is in a state where it is locked and held and cannot be removed. In addition, in the state which bent the four lower fitting protrusion parts 33 to the left-right outer side, and canceled engagement with the four protrusion parts 37, the left engaged surface 14c, and the right engaged surface 15c, the 1st main-body part 10 By pulling down from the second main body 30, the first main body 10 can be detached from the second main body 30.

以下では、相手コネクタ80を第1コネクタ部12及び第2コネクタ部13に嵌合させる方法及び作用について説明する。まず、上記のように相手コネクタ80の嵌合突起部83が第1コネクタ部12及び第2コネクタ部13に嵌合可能となっているが、具体的には、嵌合突起部83を下方から第1コネクタ部12又は第2コネクタ部13に挿入し押し上げると、図5等に示すように、相手ハウジング81の小突起部84の上部のテーパ面84aが第1コネクタ部12又は第2コネクタ部13の前後端部の内側面に当接し、更に上方に押し上げると相手ハウジング81が前後内側に弾性変形して撓み、小突起部84が第1コネクタ部12又は第2コネクタ部13の前後端面を上動し、その上部にある前後一対に設けられる小孔部18を小突起部84が乗り越えた時点で相手ハウジング81の弾性変形が元に戻り、小突起部84の下面が小孔部18の上面と対向するように位置する。   Below, the method and effect | action which fit the other party connector 80 to the 1st connector part 12 and the 2nd connector part 13 are demonstrated. First, as described above, the fitting projection 83 of the mating connector 80 can be fitted to the first connector portion 12 and the second connector portion 13. Specifically, the fitting projection 83 is viewed from below. When inserted into the first connector portion 12 or the second connector portion 13 and pushed up, as shown in FIG. 5 and the like, the tapered surface 84a of the upper portion of the small projection portion 84 of the mating housing 81 has the first connector portion 12 or the second connector portion. 13 is contacted with the inner surface of the front and rear end portions and further upwardly pushed, the mating housing 81 is elastically deformed and bent in the front and rear inner sides, and the small projection portion 84 urges the front and rear end surfaces of the first connector portion 12 or the second connector portion 13. When the small protrusion 84 gets over the small holes 18 provided on the pair of front and rear at the upper part, the elastic deformation of the mating housing 81 returns to the original state, and the lower surface of the small protrusion 84 is the bottom of the small holes 18. Opposite the top surface Sea urchin is located.

このとき相手ハウジング81の嵌合突起部83の上面が第1コネクタ部12又は第2コネクタ部13の上端面に接触するとともに小突起部84が小孔部18に引っ掛かって下方に抜けない状態となり、図5に示すようにコンタクト20の接触部20dが相手コネクタ80のコンタクト受容孔部82を介して電気ケーブル70の導体部71と当接接触して電気接続状態となる。なお、小突起部84を前後内側に押して相手ハウジング81を弾性変形させて小突起部84と小孔部18との係合を解除した状態で相手コネクタ80を下方に引き下げることにより、相手コネクタ80を第1コネクタ部12又は第2コネクタ部13から外すことができる。   At this time, the upper surface of the fitting projection 83 of the mating housing 81 comes into contact with the upper end surface of the first connector portion 12 or the second connector portion 13, and the small projection portion 84 is caught by the small hole portion 18 so that it does not come out downward. As shown in FIG. 5, the contact portion 20 d of the contact 20 comes into contact with the conductor portion 71 of the electric cable 70 through the contact receiving hole portion 82 of the mating connector 80 to be in an electrically connected state. The mating connector 80 is pulled down in a state where the mating housing 81 is elastically deformed by pushing the small projecting portion 84 in the front and rear and the small projection portion 84 and the small hole portion 18 are disengaged. Can be removed from the first connector portion 12 or the second connector portion 13.

以上、相手コネクタ80を第1コネクタ部12又は第2コネクタ部13に嵌合させる方法、第2本体部30を支持部材60に固定支持させる方法、そして、第2本体部30に第1本体部10を嵌合させる方法について説明したが、これらの嵌合又は固定支持の順序については特に制限はなく、例えば、第2本体部30に第1本体部10を嵌合させてから、第2本体部30を支持部材60に固定支持させた状態で相手コネクタ80を第1コネクタ部12又は第2コネクタ部13に嵌合させてもよいし、予め第2本体部30を支持部材60に固定支持させ、相手コネクタ80を第1コネクタ部12又は第2コネクタ部13に嵌合させた状態で、第1本体部10を第2本体部30に嵌合させるようにしてもよい。   The method for fitting the mating connector 80 to the first connector portion 12 or the second connector portion 13, the method for fixing and supporting the second body portion 30 to the support member 60, and the first body portion to the second body portion 30. Although the method of fitting 10 has been described, there is no particular limitation on the order of fitting or fixing support. For example, after fitting the first body 10 to the second body 30, the second body The mating connector 80 may be fitted to the first connector part 12 or the second connector part 13 in a state where the part 30 is fixedly supported by the support member 60, or the second main body part 30 is fixedly supported by the support member 60 in advance. Then, the first main body portion 10 may be fitted to the second main body portion 30 in a state where the mating connector 80 is fitted to the first connector portion 12 or the second connector portion 13.

ところで、本実施形態における発光装置1は、上述したように、第1コネクタ部12に嵌合接続された相手コネクタ80と第2コネクタ部13に嵌合接続された相手コネクタ80とを、LED光源50を介することなく直接電気接続させることができるようになっている。具体的には、図11(a)に示すように、6本の接触部20dが全てLED端子51と電気接続されるとともに、第1コネクタ部12側の3本の接触部20dと第2コネクタ部13側の3本の接触部20dとがLED光源50を介することなく直接電気接続される構成となっている。   By the way, as described above, the light emitting device 1 according to the present embodiment includes the mating connector 80 fitted and connected to the first connector portion 12 and the mating connector 80 fitted and connected to the second connector portion 13 as an LED light source. Direct electrical connection can be made without going through 50. Specifically, as shown in FIG. 11A, all the six contact portions 20d are electrically connected to the LED terminal 51, and the three contact portions 20d on the first connector portion 12 side and the second connector are connected. The three contact portions 20d on the side of the portion 13 are directly electrically connected without passing through the LED light source 50.

以上のように構成されることにより、本実施形態における発光装置1では、図11(a)に示すように一端に電源90が接続され他端に相手コネクタ80が取り付けられた電気ケーブル70を用いて、相手コネクタ80を第1コネクタ部12及び第2コネクタ部13の少なくともいずれかに嵌合させることにより、相手コネクタ80を介してコンタクト20と電気ケーブル70とを電気接続させ、電源90から電気ケーブル70及びコンタクト20を介してLED端子51に電力供給を行って上記発光部52b,52r,52gを発光させることができるようになっている。   With the configuration as described above, the light emitting device 1 according to the present embodiment uses the electric cable 70 in which the power supply 90 is connected to one end and the mating connector 80 is attached to the other end, as shown in FIG. Then, the mating connector 80 is fitted into at least one of the first connector portion 12 and the second connector portion 13, whereby the contact 20 and the electric cable 70 are electrically connected via the mating connector 80. Electric power is supplied to the LED terminal 51 through the cable 70 and the contact 20 so that the light emitting portions 52b, 52r, and 52g can emit light.

また、本実施形態における発光装置1は、図11(b)に示すように、電源90に接続されている電源ケーブル70の一端に相手コネクタ80を取り付け、当該相手コネクタ80を第1及び第2コネクタ部12,13のいずれか一方に嵌合させるとともに、両端に相手コネクタ80を取り付けた電気ケーブル70を用いて、一端の相手コネクタ80を上記第1及び第2コネクタ部12,13のいずれか他方に嵌合させるとともに、他端の相手コネクタ80を別の発光装置1の第1及び第2コネクタ部12,13のいずれかに嵌合させることにより発光装置1間を電気接続させることが可能となる。なお、図11(b)では第1コネクタ部12及び第2コネクタ部13の図示を省略しているが実際は図11(a)と同じ構成である。   Moreover, as shown in FIG.11 (b), the light-emitting device 1 in this embodiment attaches the other party connector 80 to the end of the power cable 70 connected to the power supply 90, and attaches the other party connector 80 to the 1st and 2nd. One of the first and second connector parts 12 and 13 is connected to one end of the mating connector 80 using the electric cable 70 fitted to either one of the connector parts 12 and 13 and having the mating connector 80 attached to both ends. The light-emitting device 1 can be electrically connected by fitting the other connector 80 at the other end to one of the first and second connector portions 12 and 13 of another light-emitting device 1. It becomes. In addition, although illustration of the 1st connector part 12 and the 2nd connector part 13 is abbreviate | omitted in FIG.11 (b), it is the same structure as Fig.11 (a) actually.

以上のように、相手コネクタ80を端部に設けた電気ケーブル70を用いて各発光装置1を電気接続させることにより、ある発光装置1に供給される電力を他の発光装置1にも供給させることが可能となり、いわゆるデイジーチェーン状に発光装置1を電気接続させ各LED光源50の発光部52を発光させることが可能となる。また、複数の発光装置1を上記のように電気接続させた場合は、図11に示すように、LED光源50に電力供給させるための電気回路が相手コネクタ80間を電気接続させる電気回路に対して独立して設けられているため、たとえ複数の発光装置1のうちの1つの発光装置1のLED光源50が故障したような場合でも、他の発光装置1にその影響が及ぶことはない。   As described above, each light emitting device 1 is electrically connected using the electrical cable 70 provided with the mating connector 80 at the end thereof, so that the power supplied to one light emitting device 1 is also supplied to the other light emitting devices 1. Thus, the light emitting device 1 can be electrically connected in a so-called daisy chain shape so that the light emitting portions 52 of the LED light sources 50 can emit light. When the plurality of light emitting devices 1 are electrically connected as described above, the electrical circuit for supplying power to the LED light source 50 is connected to the electrical circuit for electrically connecting the mating connectors 80 as shown in FIG. Therefore, even if the LED light source 50 of one of the light emitting devices 1 fails, the other light emitting devices 1 are not affected.

以上、本実施形態における発光装置1では、端部に相手コネクタ80を取り付けた電気ケーブル70を用いて発光装置1間を電気接続させることが可能となっているため、1つ1つの発光装置1に対して電源から延びる電気ケーブルを接続させていた従来の構成と比較して、電気ケーブルの使用量を少なくすることが可能となる。よって、電気ケーブルのコストを抑えることができるとともに、配線量が減るため装置のメンテナンス等も容易に行うことができる。   As described above, in the light emitting device 1 according to the present embodiment, the light emitting devices 1 can be electrically connected using the electric cable 70 with the mating connector 80 attached to the end portion.
