As shown in FIG. 3, the DC power supply device 3 is provided so as to protrude further to the right from the right end portion 2 a of the substrate holder 2 in the drawing, and the right end portion thereof is substantially in contact with the side plate 9 a of the base 9. However, the arrangement mode of the DC power supply device 3 on the substrate holder 2 is arbitrary. A connection space 2b in which the substrate holder 2 is not interposed is formed between the right end 2a of the substrate holder 2 in the drawing and the side plate 9a.

　直流電源装置３の、図３左方には、図示しない交流電源ケーブル（商用電源）が接続される端子台１０が基板ホルダ２上に配置されており、端子台１０と直流電源装置３とは電気的に接続されている。直流電源装置３には、端子台１０から供給される交流電源を整流し、直流に変換する電源基板３ａが内蔵されており、電源基板３ａの図中右端部は、接続スペース２ｂを介してＬＥＤ基板５側に開放露出されている。 A terminal block 10 to which an AC power cable (commercial power) (not shown) is connected is arranged on the substrate holder 2 on the left side of the DC power supply device 3 in FIG. Electrically connected. The DC power supply device 3 has a built-in power supply board 3a that rectifies AC power supplied from the terminal block 10 and converts it into direct current. The right end of the power supply board 3a in the drawing is connected to the LED via the connection space 2b. The substrate 5 is exposed open.

　　ＬＥＤ基板５の図３右端部は、基板ホルダ２の右端部２ａより更に図中右方、接続スペース２ｂを介して側板９ａに当接する位置にまで突出しており、ＬＥＤ基板５の電源基板３ａと対向する位置の接続スペース２ｂ内には、電源接続金具１１が複数本、ＬＥＤ基板５の上面と電源基板３ａの下面、従って互いに対向する基板面間を上下方向に接続する形で設けられている。電源接続金具１１は、直流電源装置３からＬＥＤ基板５へＬＥＤ素子６駆動用の電力を供給することが出来る。 The right end portion of the LED substrate 5 in FIG. 3 protrudes further to the right in the drawing than the right end portion 2a of the substrate holder 2 to a position that contacts the side plate 9a via the connection space 2b. In the connection space 2b at the opposite position, a plurality of power connection fittings 11 are provided so as to connect the upper surface of the LED substrate 5 and the lower surface of the power supply substrate 3a, and thus the substrate surfaces facing each other, in the vertical direction. . The power connection fitting 11 can supply power for driving the LED element 6 from the DC power supply device 3 to the LED substrate 5.

　　なお、基板ホルダ２には、図２に示すように、透光性を有する拡散カバー１２が設けられている。 The substrate holder 2 is provided with a light diffusing cover 12 as shown in FIG.

　　ＬＥＤ照明装置１は、以上のような構成を有するので、ＬＥＤ照明装置１の組み立ては、図９に示すように、例えば、電源装置３とＬＥＤ基板５が装着された状態の基板ホルダ２とカバー１２を組み立てて光源ユニット４とし、光源ユニット４をベース９に対して取り付けることで行う。なお、こうした組立態様は、本発明の要点では無く、各種の態様が考えられる。 Since the LED lighting device 1 has the above-described configuration, the LED lighting device 1 is assembled as shown in FIG. 9, for example, the substrate holder 2 and the cover in a state where the power supply device 3 and the LED substrate 5 are mounted. 12 is assembled into the light source unit 4, and the light source unit 4 is attached to the base 9. Such an assembly mode is not the main point of the present invention, and various modes can be considered.

　　組立に際して、基板ホルダ２に電源装置３を搭載して、電源装置３とＬＥＤ基板５に対してＬＥＤ素子６の駆動用電力を供給し得るようにする必要があるが、この組立作業は以下のようにして行われる。 At the time of assembly, it is necessary to mount the power supply device 3 on the substrate holder 2 so that the power for driving the LED element 6 can be supplied to the power supply device 3 and the LED substrate 5. This is done.

　　即ち、まず、電源装置３が基板ホルダ２に取り付けられていない状態で、ＬＥＤ基板５の図３の右端部、従って、基板ホルダ２が無い接続スペース２ｂ内の、後で装着される電源装置３の電源基板３ａと直接対向し得る位置に、図４に示すように、複数のピン形状に形成された電源接続金具１１を半田付けなどで立設する。なお、この電源接続金具１１は、予め電源接続金具１１が立設された状態で基板ホルダ２に取り付けられていてもよく、更には、直流電源装置３の電源基板３ａ側に予め配置されていてもよい。 That is, first, in a state where the power supply device 3 is not attached to the substrate holder 2, the right end portion of the LED substrate 5 in FIG. 3, and thus the power supply device 3 to be mounted later in the connection space 2 b without the substrate holder 2. As shown in FIG. 4, a plurality of pin-shaped power supply fittings 11 are erected by soldering or the like at positions that can directly face the power supply board 3a. The power connection fitting 11 may be attached to the substrate holder 2 in a state where the power connection fitting 11 is erected in advance, and is further disposed in advance on the power supply substrate 3a side of the DC power supply device 3. Also good.

　電源接続金具１１が電源基板３ａに立設された状態で、直流電源装置３を、図３の上方から、基板ホルダ２に向けて図中下方に向けて、電源基板３ａとＬＥＤ基板５が平行に徐々に接近する形で移動させて、電源基板３ａに設けられた図示しない、電源金具装着穴に電源接続金具１１の先端を挿入係合させ（又は、電源基板３ａ側に予め設けられた電源接続金具１１の先端をＬＥＤ基板５に設けられた図示しない電源接続金具装着穴にその先端を挿入係合させ）、その状態で直流電源装置３を基板ホルダ２に固着させると共に、電源接続金具１１と電源基板３ａ（又はＬＥＤ基板５）を半田付けなどで電気的に接続する。 With the power supply fitting 11 standing on the power supply board 3a, the power supply board 3a and the LED board 5 are parallel with the DC power supply 3 being directed from the upper side of FIG. The tip of the power connection fitting 11 is inserted into and engaged with a power supply fitting mounting hole (not shown) provided in the power supply board 3a (or a power supply provided in advance on the power supply board 3a side). The tip of the connection fitting 11 is inserted into and engaged with a power connection fitting mounting hole (not shown) provided on the LED board 5), and the DC power supply 3 is fixed to the substrate holder 2 in this state, and the power supply fitting 11 And the power supply board 3a (or LED board 5) are electrically connected by soldering or the like.

なお、電源基板３ａとＬＥＤ基板５間の接続に用いられる電源接続金具１１は、図３及び４に示すような直線的なピン形状のものの他に、ＬＥＤ基板５及び電源基板３ａとの間で、両者の基板面を互いに接近させ、どちらかに設けられた電源接続金具１１の先端を他方の基板に挿入するだけで電気的な接続を図ることの出来る（従って、半田付けが不要）、公知のコネクタ機構を有する金具を使用することもできる。 In addition, the power supply metal fitting 11 used for the connection between the power supply board 3a and the LED board 5 is between the LED board 5 and the power supply board 3a in addition to the linear pin shape as shown in FIGS. It is possible to achieve electrical connection by simply bringing both board surfaces close to each other and inserting the tip of the power supply fitting 11 provided on either board into the other board (thus, no soldering is required). It is also possible to use a metal fitting having a connector mechanism.

即ち、ＬＥＤ基板５及び電源基板３ａとの間で、両者の基板面を互いに接近させることで、どちらかの基板に予め装着されていた電源接続金具が、他方の基板と電気的に接続され得るような構成であれば、電源接続金具の構成は、任意である。 That is, by bringing the two substrate surfaces closer to each other between the LED substrate 5 and the power supply substrate 3a, the power supply fittings that are mounted in advance on either substrate can be electrically connected to the other substrate. If it is such a structure, the structure of a power supply connection metal fitting is arbitrary.

更に、図５に示すように、電源接続金具１１として、中間部分に屈曲部１１ａが形成された接続ピンを用いると、電源接続金具１１による電源基板３ａとＬＥＤ基板５間の接続後に於いて、電源基板３ａとＬＥＤ基板５間の熱膨張差などで相対的な変位が生じた場合でも、当該変位は、屈曲部１１ａで吸収され、電源基板３ａとＬＥＤ基板５間に有害な応力が作用することを効果的に防止することが出来る。 Furthermore, as shown in FIG. 5, when a connection pin having a bent portion 11 a formed in the middle portion is used as the power supply fitting 11, after the connection between the power supply board 3 a and the LED board 5 by the power supply fitting 11, Even when a relative displacement occurs due to a difference in thermal expansion between the power supply substrate 3a and the LED substrate 5, the displacement is absorbed by the bent portion 11a, and harmful stress acts between the power supply substrate 3a and the LED substrate 5. This can be effectively prevented.

　　こうすることで、直流電源装置３を基板ホルダ２上の所定位置に配置する動作を行うだけで、直流電源装置３とＬＥＤ基板５とを電源接続金具１１を介して接続することが出来るので、直流電源装置３を基板ホルダ２に配置固定した後に、わざわざ電源ケーブルで直流電源装置３とＬＥＤ基板５との間を接続する必要が無くなり、組立作業が効率化される。 By doing so, the DC power supply 3 and the LED board 5 can be connected via the power supply fitting 11 only by performing the operation of arranging the DC power supply 3 at a predetermined position on the substrate holder 2. After the DC power supply device 3 is arranged and fixed on the substrate holder 2, it is not necessary to bother to connect the DC power supply device 3 and the LED substrate 5 with a power cable, so that the assembly work is made efficient.

　　なお、直流電源装置３の基板ホルダ２に対する配置固定作業及び電源基板３ａとＬＥＤ基板５間の電源接続金具１１による接続作業を円滑に行えるように、図６及び７に示すように、位置決めピン１３と位置決め穴１５を、接続スペース２ｂの電源基板３ａとＬＥＤ基板５にそれぞれ設け、直流電源装置３を基板ホルダ２に搭載する際に、電源基板３ａ又はＬＥＤ基板５に設けられた位置決めピン１３を、ＬＥＤ基板５又は電源基板３ａに設けられた位置決め穴１５に陥入係合させる形で直流電源装置３を基板ホルダ２に搭載するだけで、電源接続金具１１による電源基板３ａとＬＥＤ基板５間の接続が完了するように構成することも可能である。なお、位置決めピン１３及び位置決め穴１５は、接続スペース２ｂ内で電源接続金具１１による電源基板３ａとＬＥＤ基板５間の接続位置の近傍に配置することが、位置決めピン１３及び位置決め穴１５による直流電源装置３の配置に際して、作業者が電源接続金具１１の位置を容易に確認しながら配置作業を行うことが出来るので、電源基板３ａとＬＥＤ基板５間の接続作業を円滑に行う上で、望ましい。 As shown in FIGS. 6 and 7, positioning pins 13 are arranged so that the arrangement and fixing work of the DC power supply device 3 with respect to the substrate holder 2 and the connection work between the power supply board 3 a and the LED board 5 by the power supply fitting 11 can be performed smoothly. And positioning holes 15 are provided in the power supply board 3a and the LED board 5 in the connection space 2b, respectively, and when the DC power supply 3 is mounted on the board holder 2, the positioning pins 13 provided on the power supply board 3a or the LED board 5 are provided. By simply mounting the DC power supply device 3 on the substrate holder 2 so as to be engaged with the positioning holes 15 provided in the LED substrate 5 or the power supply substrate 3a, the power supply connection bracket 11 can be connected between the power supply substrate 3a and the LED substrate 5. It is also possible to configure so that the connection is completed. The positioning pin 13 and the positioning hole 15 are arranged in the vicinity of the connection position between the power supply board 3a and the LED board 5 by the power supply fitting 11 in the connection space 2b. When the apparatus 3 is arranged, the operator can perform the arrangement work while easily confirming the position of the power supply fitting 11, which is desirable for smoothly connecting the power supply board 3 a and the LED board 5.

　　なお、位置決めピン１３と位置決め穴１５の態様は、図６及び７に示すように、円柱状のピン１３及び円形の穴１５に限ることは無く、図８に示すように、半円形状のピン１３及び穴１５を用いることも可能で有り、さらに、その設置位置も、電源接続金具１１の接続位置の近傍であれば、どの位置でも良い。 The mode of the positioning pin 13 and the positioning hole 15 is not limited to the cylindrical pin 13 and the circular hole 15 as shown in FIGS. 6 and 7, but a semicircular pin as shown in FIG. 13 and the hole 15 can be used, and the installation position thereof may be any position as long as it is in the vicinity of the connection position of the power connection fitting 11.

なお、位置決めピン１３を直流電源装置３の電源基板３ａ側に設け、位置決め穴１５をＬＥＤ基板５側に設けた場合、図１２に示すように、直流電源装置３を基板ホルダ２に装着し、位置決めピン１３をＬＥＤ基板５に穿設された位置決め穴１５に陥入係合させた状態、即ち、直流電源装置３の基板ホルダ２への装着が完了して、電源接続金具１１の接続も完了した状態で、位置決めピン１３の先端１３ａのＬＥＤ基板５表面からの突出高さｈが、ＬＥＤ素子６のＬＥＤ基板５での装着（実装）高さＨ以下となるように。位置決めピン１３の長さを設定しておくと、ＬＥＤ照明装置１の使用時に、位置決めピン１３の影がカバー１２側、即ち図１２下方に投影されて、照明品質が低下することが防止されるので、好都合である。 When the positioning pins 13 are provided on the power supply board 3a side of the DC power supply device 3 and the positioning holes 15 are provided on the LED board 5 side, the DC power supply device 3 is mounted on the substrate holder 2 as shown in FIG. The positioning pin 13 is inserted into the positioning hole 15 formed in the LED board 5 and engaged, that is, the mounting of the DC power supply device 3 to the board holder 2 is completed, and the connection of the power connection fitting 11 is also completed. In this state, the protruding height h of the tip 13a of the positioning pin 13 from the surface of the LED substrate 5 is set to be equal to or less than the mounting height H of the LED element 6 on the LED substrate 5. If the length of the positioning pin 13 is set in advance, the shadow of the positioning pin 13 is projected to the cover 12 side, that is, the lower side of FIG. So it is convenient.

　　なお、ＬＥＤ素子６が２枚のＬＥＤ基板５、５に搭載されている場合で、それら２枚のＬＥＤ基板５、５に対して単一の直流電源装置３から電力を供給する場合には、図１０及び１１に示すように、基板ホルダ２に直列に並べる形で設けられた２枚のＬＥＤ基板５、５の互いに対向する端部５ａ，５ａに対応する形で、例えば基板ホルダ２のほぼ中央位置に図１０上下方向に貫通した接続スペース２ｂを形成する。そして当該接続スペース２ｂ上に、直流電源装置３を配置すると共に、接続スペース２ｂを介して当該基板ホルダ２の電源基板３ａと各ＬＥＤ基板５、５との間を２つの電源接続金具１１，１１で接続するように構成することで、直流電源装置３からの電源の供給を行うように構成することが出来る。なお、接続スペース２ｂは、図１１に示すように、基板ホルダ２に形成された穴でもよく、また基板ホルダ２を２分割に構成して、分割された基板ホルダ２、２間に接続スペース２ｂを形成するように構成することも可能である。この場合、分割された基板ホルダ２，２間は、図示しない適当な接続部材で接続されることとなる。 In the case where the LED element 6 is mounted on the two LED boards 5 and 5 and when power is supplied from the single DC power supply device 3 to the two LED boards 5 and 5, As shown in FIGS. 10 and 11, for example, in the form corresponding to the end portions 5 a, 5 a facing each other of the two LED boards 5, 5 arranged in series on the board holder 2, A connection space 2b penetrating in the vertical direction in FIG. 10 is formed at the center position. A DC power supply device 3 is disposed on the connection space 2b, and two power connection fittings 11, 11 are provided between the power supply board 3a of the board holder 2 and the LED boards 5, 5 via the connection space 2b. It is possible to configure so that power is supplied from the DC power supply device 3. The connection space 2b may be a hole formed in the substrate holder 2 as shown in FIG. 11, or the connection space 2b is formed between the divided substrate holders 2 and 2 by configuring the substrate holder 2 in two. It is also possible to configure so as to form. In this case, the divided substrate holders 2 and 2 are connected by an appropriate connection member (not shown).
