Description

本発明は、主に生活道路や街路などに設置される防犯灯、道路灯および街路灯などに好適な照明装置に関する。 The present invention relates to a lighting device suitable for a crime prevention light, a road light, a street light, and the like mainly installed on a living road or a street.

低消費電力の発光素子（ＬＥＤ）を光源にした照明装置は、一般家庭はもとより商業施設などでも多く設置され、屋外に設置する街路灯などの照明装置への採用も進んでいる。この照明装置は、本体の内部に発光素子を複数配列し、下方に向けて照明光を照射するようにしたものである。 Many lighting devices using light-emitting elements (LEDs) with low power consumption as light sources are installed not only in general homes but also in commercial facilities and the like, and are increasingly used in lighting devices such as street lamps installed outdoors. In this illumination device, a plurality of light emitting elements are arranged inside a main body, and illumination light is irradiated downward.

このような照明装置の設置には、例えば街路の既設の電柱を利用したり、あるいは専用の支柱を立設するようにしている。このような電柱、支柱を利用する場合は、通常、電柱、支柱に固定して延設された支管の先端に照明装置を固定するようにしている（例えば、特許文献１参照）。 For installation of such a lighting device, for example, an existing utility pole on a street is used, or a dedicated support column is erected. When such a utility pole or support is used, the illuminating device is usually fixed to the tip of a branch pipe that is fixed and extended to the utility pole or support (for example, see Patent Document 1).

この特許文献１の別実施例に開示された技術は、背面に支柱を通す開口を設けた取付部に、クランプ部が略水平に配置され、このクランプ部は支柱受け部を備え、この支柱受け部でアーム型支柱の水平に延出した先端が本体の背面の支柱用開口を貫通して差し込まれ、支柱受け部に固定されるようにしている。そして取付部には、クランプ部および電源ケーブルの結線端子の上側を覆い、光源収容部の上側の上面カバーに係合する蓋体を開閉自在の設けるというものである。 In the technology disclosed in another embodiment of Patent Document 1, a clamp portion is disposed substantially horizontally at an attachment portion provided with an opening through which a column is passed, and the clamp portion includes a column receiving portion. The tip of the arm-type column that extends horizontally at the end is inserted through the column opening on the back of the main body and is fixed to the column receiving unit. The mounting portion is provided with a lid that covers the upper side of the connection portion of the clamp portion and the power cable and engages with the upper surface cover on the upper side of the light source housing portion so as to be freely opened and closed.

上記特許文献１による場合は、光源収容部の上面カバーの基部に蓋体の後端部をヒンジにより固定し、蓋体の先端部はボルトにより上面カバーに固定するようにしている。そして上面カバーと蓋体の係合部に排水溝を形成し、この排水溝により雨水を外部へ排水するようにしている。しかしながら、排水溝を形成してあるものの塵埃などの進入で排水機能の低下あるいは不能となる懸念が残るものであり、上面カバーと蓋体の側部および後部の接合部位からの雨水などの進入を完全に阻止することはできない。また、シール材などを配設したとしても厳しい室外環境における劣化は激しく、水密性を長期間維持することは甚だ困難である。 In the case of Patent Document 1, the rear end portion of the lid body is fixed to the base portion of the upper surface cover of the light source housing portion by a hinge, and the front end portion of the lid body is fixed to the upper surface cover by a bolt. A drainage groove is formed in the engaging portion between the top cover and the lid, and rainwater is drained to the outside through the drainage groove. However, although drainage grooves are formed, there is still a concern that the drainage function will deteriorate or become impossible due to the entry of dust, etc., and rainwater etc. will enter from the joint part of the top cover and the side part of the lid and the rear part. It cannot be completely prevented. Moreover, even if a sealing material or the like is provided, deterioration in severe outdoor environments is severe, and it is extremely difficult to maintain water tightness for a long time.

このように、直射日光による高温、紫外線、あるいは暴風、融雪などによる悪影響は上面カバーが大きく受けることから、一体化することが望ましいことになる。しかしながら、支柱への取付作業および配線作業の便宜性を配慮すると、特許文献１による場合、蓋体は不可欠となる。 As described above, since the upper surface cover is greatly affected by the high temperature, ultraviolet rays, storms, and snowmelt caused by direct sunlight, it is desirable to integrate them. However, in consideration of the convenience of the mounting work and the wiring work to the support column, according to Patent Document 1, the lid is indispensable.

ところで、図２５に示すような照明装置Ａの上面カバーＡ１に係合する蓋体Ａ２を開閉可能に設け、下面に透光カバーＡ３を配設した構成において、この照明装置Ａを電柱などへ設置する場合、同図に示すような固定金具Ｂを採用している。この固定金具Ｂは、照明装置Ａ内で先端が固定される支管Ｂ１の後端にコ字状のアングル部材Ｂ２が固定されている。このアングル部材Ｂ２には締結バンドＣを挿通するスリットＢ３が形成されている。 By the way, in a configuration in which a lid A2 that engages with the upper surface cover A1 of the illumination device A as shown in FIG. In this case, a fixing bracket B as shown in FIG. In the fixing bracket B, a U-shaped angle member B2 is fixed to the rear end of the branch pipe B1 whose front end is fixed in the lighting device A. The angle member B2 is formed with a slit B3 through which the fastening band C is inserted.

このように構成された固定金具Ｂは、図２６に示すように電柱などの柱状構造物Ｐなどへ締結バンドＣで固定されることになる。しかしながら上面カバーＡ１に連設した蓋体Ａ２を開くと、図２７に示すように固定金具Ｂのアングル部材Ｂ２に当接し、蓋体Ａ２の内部を完全に開放することができず、照明装置Ａの設置作業および配線作業が困難となる。 The fixing bracket B configured as described above is fixed to a columnar structure P such as a utility pole with a fastening band C as shown in FIG. However, when the lid A2 provided continuously to the upper surface cover A1 is opened, it contacts the angle member B2 of the fixing bracket B as shown in FIG. 27, and the interior of the lid A2 cannot be completely opened. Installation work and wiring work become difficult.

ところで、図２７のように支管Ｂ１に固定して照明装置Ａを設置にあたり、その支管Ｂ１の直径が区々である場合がある。例えば、大径が６０．５mm、中径４８．６mm、小径３４mmが既存のものであるが、この各直径の支管Ｂ１の何れをも固定できる融通性のある照明装置としなければならない。 By the way, as shown in FIG. 27, when the lighting device A is installed by being fixed to the branch pipe B1, the diameter of the branch pipe B1 may vary. For example, the large diameter is 60.5 mm, the medium diameter is 48.6 mm, and the small diameter is 34 mm. However, it is necessary to provide a flexible lighting device that can fix any of the branch pipes B1 having the respective diameters.

本発明の照明装置１は、主体となる上面カバー２がアルミダイキャストなどの耐食性に優れた素材により一体成形されたもので、この上面カバー２の下面の開口部は透光カバー３がシールパッキン３Ａを介在させ、取付ボス２ｃにネジ孔３ａを介してネジ止めされる。また、上面カバー２の後側部は図１、図３、図６などに示すように傾斜状部２ａが形成され、この傾斜状部２ａの一方の傾斜端部２ａ−１に、傾斜状部２ａの開口形状に一致する蓋体４が蝶番４ａにより開閉可能に連結されている。この蓋体４の蝶番４ａを備えない他方の傾斜端部２ａ−１を取付ネジにより上面カバー２へ固定することにより、上面カバー２の後端面と蓋体４の前端面が図５に示すように連接するようにしている。この場合、蓋体４と透光カバー３の端部の対向部の外表面が面一となるようにしておき、照射面に一体感のある造形処理となるようにする。 In the lighting device 1 of the present invention, an upper surface cover 2 as a main body is integrally formed of a material having excellent corrosion resistance such as aluminum die-casting, and a translucent cover 3 is attached to a seal packing at an opening portion on the lower surface of the upper surface cover 2. 3A is interposed, and it is screwed to the mounting boss 2c through the screw hole 3a. Further, as shown in FIG. 1, FIG. 3, FIG. 6, and the like, an inclined portion 2a is formed on the rear side portion of the top cover 2, and an inclined portion 2a-1 is formed on one inclined end portion 2a-1 of the inclined portion 2a. A lid 4 matching the opening shape of 2a is connected by a hinge 4a so as to be opened and closed. As shown in FIG. 5, the rear end surface of the upper cover 2 and the front end surface of the cover 4 are fixed to the upper cover 2 by fixing the other inclined end 2a-1 of the cover 4 that does not have the hinge 4a. To be connected to. In this case, the outer surface of the opposing part of the edge part of the cover body 4 and the translucent cover 3 is made into the same surface, and it is set as the modeling process with a feeling of unity in an irradiation surface.

前記上面カバー２には図５に示すように固定金具Ｂの支管Ｂ１を挿通する通孔２ｂが形成され、空室内部に複数の取付ボス２ｃおよび後述する光源部５のヒートシンク２ｄなどが図７に示すように一体に成形されている。前記ヒートシンク２ｄには光源部５を配設した熱伝導板６が固定され、各発光素子５ａ（図１８参照）から発生する発熱をヒートシンク２ｄへ導くようにしている。ヒートシンク２ｄは前記発熱を吸収し、上面カバー２から装置外部へ放散する。前記光源部５および熱伝導板６はホルダー７によりヒートシンク２ｄに固定される。また、光源部５の後部には電源部８が配置され、この電源部８から商用交流電源を電圧変換した直流の駆動電源がリード線９により光源部５に供給される。 As shown in FIG. 5, the upper surface cover 2 is formed with a through hole 2b through which the branch pipe B1 of the fixing bracket B is inserted, and a plurality of mounting bosses 2c and a heat sink 2d of the light source unit 5 to be described later are formed in the inner space. As shown in FIG. A heat conducting plate 6 provided with a light source unit 5 is fixed to the heat sink 2d, and heat generated from each light emitting element 5a (see FIG. 18) is guided to the heat sink 2d. The heat sink 2d absorbs the heat and dissipates it from the top cover 2 to the outside of the apparatus. The light source unit 5 and the heat conducting plate 6 are fixed to the heat sink 2d by a holder 7. In addition, a power supply unit 8 is disposed at the rear of the light source unit 5, and a DC driving power obtained by converting a commercial AC power supply from the power supply unit 8 is supplied to the light source unit 5 through a lead wire 9.

前記電源部８へ商用交流電源を導くリード線９は上面カバー２の傾斜状部２ａの空室内に配置した端子台１０に接続され、商用交流電源用のケーブルは支管Ｂ１内を通じて外部へ引き出される。また、前記傾斜状部２ａの空間内には、通孔２ｂから封止リング１１を介在させて差し込まれた支管Ｂ１の端部を固定するための固定金具１２が配設されている。 The lead wire 9 for guiding the commercial AC power source to the power source unit 8 is connected to the terminal block 10 disposed in the empty space of the inclined portion 2a of the top cover 2, and the cable for the commercial AC power source is drawn out through the branch B1. . A fixing fitting 12 for fixing the end portion of the branch pipe B1 inserted through the through hole 2b with the sealing ring 11 interposed is disposed in the space of the inclined portion 2a.

前記固定金具１２は図７に示すように、端部が取付ボス２ｃに図１０、図１１に示すようにネジ止めされる第１の支持部材１２ａ、と端部が取付ボス２ｃに図９〜図１１に示すようにネジ止めされる第２の支持部材１２ｂとからなる。第１の支持部材１２ａの中央には支管Ｂ１の軸心方向に並行する曲部１２ａ−１が形成されており、一方、第２の支持部材１２ｂの中央には支管Ｂ１の軸心方向に並行する平坦段部１２ｂ−１が形成されており、この平坦段部１２ｂ−１には図５に示すように固定用の固定ネジ１２ｂ−２および位置決めネジ１２ｂ−３を備える。 As shown in FIG. 7, the fixing metal 12 has a first support member 12a whose end is screwed to the mounting boss 2c as shown in FIG. 10 and FIG. As shown in FIG. 11, it consists of a second support member 12b that is screwed. A curved portion 12a-1 parallel to the axial direction of the branch pipe B1 is formed at the center of the first support member 12a, while parallel to the axial direction of the branch pipe B1 at the center of the second support member 12b. The flat step portion 12b-1 is formed, and the flat step portion 12b-1 includes a fixing screw 12b-2 for fixing and a positioning screw 12b-3 as shown in FIG.

固定金具１２はこのように構成されていることから、直径の異なる各種の支管Ｂ１の固定が可能となる。即ち、相対的に最も大径の支管Ｂ１を固定する場合は、図９に示すように支持部材１２ａを取り除き、取付ボス２ｃにネジ止めされた第２の支持部材１２ｂ上に支管Ｂ１の端部を差し込み、位置決めネジ１２ｂ−３により支管Ｂ１を定位置に位置決めした後、固定ネジ１２ｂ−２を緊締して支管Ｂ１を上面カバー２に一体成形された一対の凸条２ｅに押し付けて取付作業を完了する。 Since the fixing bracket 12 is configured in this way, it is possible to fix various branch pipes B1 having different diameters. That is, when fixing the branch pipe B1 having the relatively largest diameter, the support member 12a is removed as shown in FIG. 9, and the end portion of the branch pipe B1 is placed on the second support member 12b screwed to the mounting boss 2c. After the branch pipe B1 is positioned at a fixed position by the positioning screw 12b-3, the fixing screw 12b-2 is tightened and the branch pipe B1 is pressed against the pair of ridges 2e formed integrally with the upper surface cover 2 to perform the mounting operation. Complete.

また、中径の支管Ｂ１を固定する場合は、図１０に示すように第１の支持部材１２ａを取付ボス２ｃにネジ止めするとともに、第２の支持部材１２ｂを取付ボス２ｃにネジ止めする。そして、支管Ｂ１の端部を第１、第２の支持部材１２ａ、１２ｂ間に差し込み、位置決めネジ１２ｂ−３により支管Ｂ１を定位置に位置決めした後、固定ネジ１２ｂ−２を緊締して支管Ｂ１を第１の支持部材１２ａに押し付けて取付作業を完了する。 Further, when fixing the medium-diameter branch pipe B1, as shown in FIG. 10, the first support member 12a is screwed to the mounting boss 2c, and the second support member 12b is screwed to the mounting boss 2c. The end of the branch pipe B1 is inserted between the first and second support members 12a and 12b, and the branch pipe B1 is positioned at a fixed position by the positioning screw 12b-3, and then the fixing screw 12b-2 is tightened to tighten the branch pipe B1. Is pressed against the first support member 12a to complete the mounting operation.

さらに、小径の支管Ｂ１を固定する場合は、図１１に示すように第１の支持部材１２ａを取付ボス２ｃにネジ止めするとともに、第２の支持部材１２ｂを、その平坦段部１２ｂ−１の凸面が上方を向くようにして取付ボス２ｃにネジ止めする。そして、支管Ｂ１の端部を第１、第２の支持部材１２ａ、１２ｂ間に差し込み、位置決めネジ１２ｂ−３により支管Ｂ１を定位置に位置決めした後、固定ネジ１２ｂ−２を緊締して支管Ｂ１を第１の支持部材１２ａに押し付けて取付作業を完了する。 Further, when the small-diameter branch pipe B1 is fixed, the first support member 12a is screwed to the mounting boss 2c as shown in FIG. 11, and the second support member 12b is fixed to the flat step portion 12b-1. Screw onto the mounting boss 2c with the convex surface facing upward. The end of the branch pipe B1 is inserted between the first and second support members 12a and 12b, and the branch pipe B1 is positioned at a fixed position by the positioning screw 12b-3, and then the fixing screw 12b-2 is tightened to tighten the branch pipe B1. Is pressed against the first support member 12a to complete the mounting operation.

以上のように支管Ｂ１の取付作業を行っている間は、蓋体４は図６に示すように、支管Ｂ１などと干渉しない状態で拡開するので、傾斜状部２ａが完全に開放され、支管Ｂ１の取付作業および端子台１０への配線作業を容易に行うことができる。本発明の照明装置１はこのように構成されていることから、図１２に示すように柱状構造物Ｐへ固定金具Ｂにより取り付けた場合、上面カバー２に接続部分がないことから耐候性および水密性を向上することができる。また、蓋体４が装置本体の下面に位置するようになることから、雨水などの進入を確実に阻止することができる。 While performing the attachment work of the branch pipe B1 as described above, as shown in FIG. 6, the lid body 4 is expanded without interfering with the branch pipe B1, etc., so that the inclined portion 2a is completely opened, The attachment work of the branch pipe B1 and the wiring work to the terminal block 10 can be easily performed. Since the illuminating device 1 of the present invention is configured in this way, when it is attached to the columnar structure P with the fixing bracket B as shown in FIG. Can be improved. In addition, since the lid 4 is positioned on the lower surface of the apparatus main body, it is possible to reliably prevent entry of rainwater or the like.

つぎに、電源部８の構成について詳細に説明する。電源部８は商用交流電源を降圧した直流電源に変換して光源部５へ供給する電源回路、前記直流電源で発光素子５ａを点灯する点灯回路、そして装置本体外の環境の明度を判断して発光素子５ａを点滅する点滅制御回路を備える。 Next, the configuration of the power supply unit 8 will be described in detail. The power supply unit 8 converts a commercial AC power source into a stepped down DC power source and supplies the light source unit 5 with power, a lighting circuit for lighting the light emitting element 5a with the DC power source, and the brightness of the environment outside the apparatus main body. A blinking control circuit for blinking the light emitting element 5a is provided.

前記電源部８は図７、図８に示すように中空の筺状ケース８ａと、この筺状ケース８ａの開口面を覆うスライド板８ｂとが一体構成されたもので、筺状ケース８ａの内部に前記電源回路、点灯回路、点滅制御回路を実装した配線基板８ｃを収容している。前記スライド板８ｂの外周は筺状ケース８ａの外周から張り出したフランジ状となっており、このフランジ状部の四隅にダルマ孔８ｂ−１が形成されている。 As shown in FIGS. 7 and 8, the power supply unit 8 includes a hollow bowl-shaped case 8a and a slide plate 8b that covers the opening surface of the bowl-shaped case 8a. A wiring board 8c on which the power supply circuit, the lighting circuit, and the blinking control circuit are mounted is accommodated. The outer periphery of the slide plate 8b has a flange shape that protrudes from the outer periphery of the bowl-shaped case 8a, and Dharma holes 8b-1 are formed at the four corners of the flange-shaped portion.

前記筺状ケース８ａの側部には図１３に示すように配線基板８ｃに受光素子８ｃ−１が実装されている。この受光素子８ｃ−１に対向する筺状ケース８ａの側壁には通孔８ａ−１が形成されており、上面カバー２の両側部に形成した採光部２ｆから周囲環境の外光を導入するようにしている。即ち、上面カバー２の前記通孔８ａ−１に対面する位置は凹陥した状態に形成されており、この採光部２ｆの奥部立壁に通孔２ｆ−１を形成している。そして、この通孔２ｆ−１と前記通孔８ａ−１を共軸として透明素材で形成された採光パッキン１３が嵌装されている。なお、採光部２ｆの側壁２ｆ−２は装置本体の長手方向（道路軸方向）の両側に長軸方向からの光を遮断する遮光部となり、庇壁２ｆ−３は上方からの光を遮断し、受光素子８ｃ−１へ入射するノイズとなる光を制限することができる。 As shown in FIG. 13, a light receiving element 8c-1 is mounted on a wiring board 8c on the side of the bowl-shaped case 8a. A through hole 8a-1 is formed in the side wall of the bowl-shaped case 8a facing the light receiving element 8c-1, so that external light from the surrounding environment is introduced from the daylighting portions 2f formed on both sides of the top cover 2. I have to. That is, the position of the top cover 2 facing the through hole 8a-1 is formed in a recessed state, and the through hole 2f-1 is formed in the deep vertical wall of the daylighting portion 2f. A daylighting packing 13 made of a transparent material is fitted around the through hole 2f-1 and the through hole 8a-1. The side wall 2f-2 of the daylighting unit 2f is a light shielding unit that blocks light from the long axis direction on both sides in the longitudinal direction (road axis direction) of the apparatus body, and the eaves wall 2f-3 blocks light from above. The light that becomes noise incident on the light receiving element 8c-1 can be limited.

以上のように構成された電源部８の側部の一方に受光素子８ｃ−１を設けるように構成した場合、この受光素子８ｃ−１を上面カバー２の採光部２ｆの任意の一方に対向させて配置することが可能となる。かかる機能は、照明装置１を設置した周囲の住宅や建築物などの照明施設からの照射光がノイズとなり受光素子８ｃ−１で検知され、本来点灯すべき夜間において点灯しないという誤動作を生じる場合に対応することができる。 When the light receiving element 8c-1 is provided on one of the side portions of the power supply unit 8 configured as described above, the light receiving element 8c-1 is opposed to any one of the daylighting portions 2f of the top cover 2. Can be arranged. Such a function is used when the light emitted from a lighting facility such as a surrounding house or building where the lighting device 1 is installed becomes noise and is detected by the light receiving element 8c-1 and causes a malfunction that does not light at night when it should be lit. Can respond.

このような場合、上面カバー２の採光部２ｆの光ノイズの進入側への受光素子８ｃ−１の配置を避け、光ノイズの影響を受けない採光部２ｆを選定して電源部８の配設が可能となるようにしている。即ち、電源部８が図６に示すように同図の上側の採光部２ｆから採光するようにした場合において、光ノイズの影響が確認されたとき、ダルマ孔８ｂ−１の小径部を固定している取付ネジ１４を緩め、スライド板８ｂスライドさせてダルマ孔８ｂ−１の大径部から取付ネジ１４の頭部を外すことにより、電源部８の全体を１８０°回転することができ、図６の下側の採光部２ｆから採光できるように配設方向を変更することができる。 In such a case, the arrangement of the power supply unit 8 is selected by avoiding the arrangement of the light receiving element 8c-1 on the light noise entrance side of the daylighting unit 2f of the top cover 2, and selecting the daylighting unit 2f that is not affected by the optical noise. Is made possible. That is, in the case where the power supply unit 8 takes light from the upper daylighting unit 2f as shown in FIG. 6, when the influence of optical noise is confirmed, the small-diameter part of the dharma hole 8b-1 is fixed. The entire power supply unit 8 can be rotated by 180 ° by loosening the mounting screw 14 and sliding the slide plate 8b to remove the head of the mounting screw 14 from the large diameter portion of the Dharma hole 8b-1. The arrangement direction can be changed so that the light can be taken from the lower daylighting portion 2f.

即ち、電源部８を図１４、図１５に示す何れの方向にも任意に配設することが可能となるのである。なお、図１６に示すように、電源部８内の両側部に受光素子８ｃ−１を設けるとともに、スイッチＳＷ１、ＳＷ２を設けて受光素子８ｃ−１の一方または両方の選択が可能となるようにし、周囲環境の光の状態に対応できる融通性を向上することができるとともに、受光素子８ｃ−１の一方が機能しなくなった場合に他方を機能させるなど、応急の対応が可能となる。なお、受光素子８ｃ−１を両側部に設けた場合の機能処理の流れを図１７に示す。このように本発明の電源部８の構成によれば、採光部２ｆを上面カバー２の側部を設けるようにしたので、採光部を背面に設けた従来の照明装置に比較して格段に精度の高い採光が可能となる。 That is, the power supply unit 8 can be arbitrarily arranged in any direction shown in FIGS. As shown in FIG. 16, light receiving elements 8c-1 are provided on both sides in the power supply unit 8, and switches SW1 and SW2 are provided so that one or both of the light receiving elements 8c-1 can be selected. In addition to being able to improve the flexibility of responding to the light conditions of the surrounding environment, it is possible to make an emergency response such as causing one to function when one of the light receiving elements 8c-1 stops functioning. FIG. 17 shows the flow of functional processing when the light receiving element 8c-1 is provided on both sides. As described above, according to the configuration of the power supply unit 8 of the present invention, since the daylighting unit 2f is provided on the side of the upper surface cover 2, the accuracy is much higher than that of a conventional lighting device in which the daylighting unit is provided on the back surface. High daylighting is possible.

つぎに、光源部５の構成について詳細に説明する。光源部５は図１８に示すように、複数のチップ状の発光素子５ａを絶縁基板５ｂ上に実装し、熱伝導板６上に固定された２枚一組の光源エレメント５ｃと、この光源エレメント５ｃ上でスライドし、各発光素子５ａの発光光の出射方向を制御する２枚一組の光制御エレメント５ｄとの組み合わせを主体に構成される。 Next, the configuration of the light source unit 5 will be described in detail. As shown in FIG. 18, the light source unit 5 includes a plurality of chip-like light emitting elements 5a mounted on an insulating substrate 5b, a set of two light source elements 5c fixed on the heat conducting plate 6, and the light source element. The combination is mainly composed of a pair of light control elements 5d that slide on 5c and control the emission direction of the emitted light of each light emitting element 5a.

前記光制御エレメント５ｄの１枚ごとの構成は、図１９にその詳細を示すように、基板５ｄ−１に透過孔５ｄ−２と透過孔５ｄ−３を列設し、透過孔５ｄ−３上に透明素材により成形したレンズ状の光制御部材５ｅが接着などの適宜手段により固定されている。なお、基板５ｄ−１も透明素材として光制御部材５ｅとともに一体成形するようにしてもよい。光制御部材５ｅが介在しない透過孔５ｄ−２の外周部には入射した光のいわゆるケラレを防止するためのテーパー面５ｄ−２ａが形成されている。 As shown in detail in FIG. 19, the configuration of each of the light control elements 5d is such that a transmission hole 5d-2 and a transmission hole 5d-3 are arranged in a row on the substrate 5d-1, A lens-shaped light control member 5e formed of a transparent material is fixed by appropriate means such as adhesion. The substrate 5d-1 may also be integrally formed with the light control member 5e as a transparent material. A tapered surface 5d-2a for preventing so-called vignetting of incident light is formed on the outer peripheral portion of the transmission hole 5d-2 where the light control member 5e is not interposed.

また、基板５ｄ−１の裏面には、透過孔５ｄ−２、５ｄ−３の相互間および光源部５の外部に通じる通気溝５ｄ−４が形成されており、発光素子５ａの発熱を外部へ放散できるようにし、光源エレメント５ｃと光制御エレメント５ｄ間の蓄熱を解消し、発光素子５ａを保護するようにしている。なお、光制御部材５ｅの形状、大きさ、および透過孔５ｄ−２、５ｄ−３の形状、大きさは配光設計に基づいて任意に定めることができ、本実施例に限定されるものではない。 Further, on the back surface of the substrate 5d-1, a ventilation groove 5d-4 is formed between the transmission holes 5d-2 and 5d-3 and to the outside of the light source unit 5, and heat generation of the light emitting element 5a is transmitted to the outside. The light can be dissipated, heat storage between the light source element 5c and the light control element 5d is eliminated, and the light emitting element 5a is protected. The shape and size of the light control member 5e and the shapes and sizes of the transmission holes 5d-2 and 5d-3 can be arbitrarily determined based on the light distribution design, and are not limited to this embodiment. Absent.

前記光制御エレメント５ｄはその係止凹部５ｄ−５が光源エレメント５ｃの係止凸部５ｃ−１と係合し、光制御エレメント５ｄのスライド位置が規制されるようにしている。図２０は光源エレメント５ｃ上で光制御エレメント５ｄがスライドする状態を説明するもので、同図に示すように光制御エレメント５ｄを距離ｄだけ左方へスライドさせた場合は、発光素子５ａの光軸ＳＣ上に光制御エレメント５ｄの光制御部材５ｅが位置し、距離ｄだけ右方へスライドさせた場合は、発光素子５ａの光軸ＳＣ上に光制御エレメント５ｄの透過孔５ｄ−２が位置することになる。 The light control element 5d has its locking recess 5d-5 engaged with the locking protrusion 5c-1 of the light source element 5c so that the slide position of the light control element 5d is regulated. FIG. 20 illustrates a state in which the light control element 5d slides on the light source element 5c. When the light control element 5d is slid leftward by a distance d as shown in FIG. When the light control member 5e of the light control element 5d is positioned on the axis SC and is slid to the right by the distance d, the transmission hole 5d-2 of the light control element 5d is positioned on the optical axis SC of the light emitting element 5a. Will do.

図２１は発光素子５ａの光軸ＳＣ上に光制御部材５ｅが位置した状態の断面図であり、図２２に発光素子５ａの光軸ＳＣ上に透過孔５ｄ−２が位置した状態を示す。図２１に示す発光素子５ａに対する光制御部材５ｅの配置状態とした場合は、発光素子５ａから出射した発光光は光制御部材５ｅのレンズ作用により横方向に拡散する。一方、図２２に示す状態とした場合は、発光素子５ａから出射した発光光は透過孔５ｄ−２を透過して直進する状態となる。 FIG. 21 is a cross-sectional view of a state where the light control member 5e is positioned on the optical axis SC of the light emitting element 5a. FIG. 22 shows a state where the transmission hole 5d-2 is positioned on the optical axis SC of the light emitting element 5a. In the arrangement state of the light control member 5e with respect to the light emitting element 5a shown in FIG. 21, the emitted light emitted from the light emitting element 5a is diffused in the lateral direction by the lens action of the light control member 5e. On the other hand, in the state shown in FIG. 22, the emitted light emitted from the light emitting element 5a passes through the transmission hole 5d-2 and goes straight.

図２１に示す状態では、光制御エレメント５ｄの全体から出射される照射光Ｌは図２３に示すような横方向に拡がる紡錘形の配光特性となることから、道路面の長手方向の照明に好適で、長円形の配光パターンとなり照明装置間の設置間隔を大きくすることができるとともに、鉛直角８５°以上の領域への照明光の出射（グレア）を抑制することができる。一方、図２２に示す状態では、図２４に示すようなスポット状の略円形または略台形の配光特性となることから、交差点あるいは公園などにおける照明に好適となる。光源部５をこのように構成したことから、光制御エレメント５ｄをスライドするのみで配光特性の異なる照明光が得られることになる。 In the state shown in FIG. 21, the irradiation light L emitted from the entire light control element 5d has a spindle-shaped light distribution characteristic spreading in the lateral direction as shown in FIG. 23, which is suitable for illumination in the longitudinal direction of the road surface. Thus, an elliptical light distribution pattern can be obtained, and the installation interval between the illumination devices can be increased, and the emission (glare) of illumination light to a region having a vertical angle of 85 ° or more can be suppressed. On the other hand, in the state shown in FIG. 22, the spot-like substantially circular or substantially trapezoidal light distribution characteristic as shown in FIG. 24 is obtained, which is suitable for illumination at an intersection or a park. Since the light source unit 5 is configured in this manner, illumination light having different light distribution characteristics can be obtained only by sliding the light control element 5d.

以上の説明から明らかなように、上述した本発明特有の構成を実施することにより、機能性および汎用性を向上した照明装置とすることが可能となる。 As is apparent from the above description, by implementing the above-described configuration unique to the present invention, it is possible to provide a lighting device with improved functionality and versatility.
