Description

本発明は、光源と、該光源に電力を供給する電源部と、前記光源及び電源部を保持する保持体と、該保持体を被取付部材に取付ける取付部とを備える照明装置に関する。   The present invention relates to a lighting device including a light source, a power supply unit that supplies power to the light source, a holding body that holds the light source and the power supply unit, and an attachment unit that attaches the holding body to a member to be attached.

住宅等の室内の照明に用いられる照明装置として、従来、白熱電球、蛍光灯等の光源を備える照明装置が用いられている。近年、発光ダイオード（以下ＬＥＤという）の高輝度化に伴い、従来の光源に代えて、小型、低消費電力、長寿命等の特性を有するＬＥＤを光源として備える照明装置が種々提案されている（例えば、特許文献１参照）。   2. Description of the Related Art Conventionally, lighting devices including light sources such as incandescent bulbs and fluorescent lamps have been used as lighting devices used for indoor lighting such as houses. In recent years, with the increase in luminance of light emitting diodes (hereinafter referred to as LEDs), various lighting devices have been proposed that include LEDs having characteristics such as small size, low power consumption, and long life as a light source instead of conventional light sources ( For example, see Patent Document 1).

特許文献１に開示されたＬＥＤ照明装置は、光源であるＬＥＤと、該ＬＥＤを点灯する点灯装置とを備え、前記ＬＥＤと前記点灯装置とを略同一面内に配置してある。ＬＥＤ照明装置は、前記ＬＥＤ及び点灯装置をその一面に取付けられるベース板３０２を有しており、該ベース板３０２の他面の側の略中央には、外部電源からの給電を受ける部分として引掛刃３１１を備えた引掛シーシングキャップ３０１が設けてある（図１６参照）。そして、ＬＥＤ照明装置は、天井面に設けられた引掛シーリングボディ（図示せず）の引掛刃受け穴（図示せず）に引掛刃３１１を嵌合させることにより天井面への取付が行われるように構成してある。   The LED illumination device disclosed in Patent Literature 1 includes an LED that is a light source and a lighting device that lights the LED, and the LED and the lighting device are arranged in substantially the same plane. The LED lighting device has a base plate 302 on which the LED and the lighting device can be mounted on one surface, and is hooked at a substantially central portion on the other surface side of the base plate 302 as a portion that receives power from an external power source. A hook seed cap 301 provided with a blade 311 is provided (see FIG. 16). The LED lighting device is attached to the ceiling surface by fitting the hooking blade 311 into the hooking blade receiving hole (not shown) of the hooking sealing body (not shown) provided on the ceiling surface. It is configured.

特開２００３−８６００６号公報JP 2003-86006 A

ところで、住宅等の室内の照明に用いられる照明装置においては特に、天井面から照明装置が大きく突設していると、美観を損ねると共に、限られた室内空間を占有してしまい、好ましくないため、照明装置を薄型化したいという要望があった。特許文献１に係る照明装置においては、点灯装置とＬＥＤとを略同一面内に配置して、ＬＥＤの光出射方向である上下方向に重なり合わないように配置してあるから、確かに、点灯装置とＬＥＤを上下方向に重なり合う配置を採用した照明装置と比較して、天井面からの突設高さを低減することができ、薄型化することができる。しかしながら、引掛シーリングキャップ３０１の引掛刃３１１がベース板３０２の他面の側（ＬＥＤ及び点灯装置が配置される一面と反対側）に突出しており、また引掛シーリングキャップとＬＥＤ又は点灯装置とが上下方向に一部が重なり合う配置となっているから、これらの分だけ上下方向の厚み、換言すると天井面からの突設高さが増してしまうという問題があった。   By the way, especially in the illuminating device used for indoor lighting of a house or the like, if the illuminating device protrudes greatly from the ceiling surface, it is not preferable because it impairs the beauty and occupies a limited indoor space. There was a request to make the lighting device thinner. In the illumination device according to Patent Document 1, the lighting device and the LED are arranged in substantially the same plane so as not to overlap in the vertical direction that is the light emission direction of the LED. Compared with an illuminating device that employs an arrangement in which the device and the LED overlap in the vertical direction, the protruding height from the ceiling surface can be reduced and the device can be made thinner. However, the hooking blade 311 of the hooking sealing cap 301 protrudes to the other side of the base plate 302 (the side opposite to the one where the LED and lighting device are arranged), and the hooking sealing cap and the LED or lighting device are vertically moved. Since the arrangement is partially overlapped in the direction, there is a problem that the thickness in the vertical direction, in other words, the protruding height from the ceiling surface increases by these amounts.

アダプタ１により、光源及び電源部を保持する保持体であるシャーシ２が被取付部材に取付けられる。シャーシ２は、中央に円穴を有する円板状であり、アルミニウム等の金属製である。シャーシ２は、前記円穴の周囲に、該円穴に同心をなして、アダプタ１に保持される環状の天井取付部２１を有している。引掛シーリングボディ２００にアダプタ１を取付けた後、シャーシ２の円穴とアダプタ１の位置を整合させて、シャーシ２をアダプタ１の側から押し込むことにより、シャーシ２が、アダプタ１の係合突起１２により保持され、被取付部材である天井に取付けられることになる。この取付状態において、シャーシ２の略中央にアダプタ１が位置する。そして、アダプタ１は主として天井取付部２１の一面２１ａの側に配される。   The adapter 1 attaches the chassis 2, which is a holding body that holds the light source and the power supply unit, to the attached member. The chassis 2 has a disk shape with a circular hole in the center, and is made of metal such as aluminum. The chassis 2 has an annular ceiling mounting portion 21 concentric with the circular hole and held by the adapter 1 around the circular hole. After the adapter 1 is attached to the hooking sealing body 200, the position of the circular hole of the chassis 2 and the position of the adapter 1 are aligned, and the chassis 2 is pushed in from the adapter 1 side. It will be hold | maintained by and it will be attached to the ceiling which is a to-be-attached member. In this attached state, the adapter 1 is located at the approximate center of the chassis 2. The adapter 1 is mainly disposed on the one surface 21a side of the ceiling mounting portion 21.

天井取付部２１には、後述する電源基板及び制御基板を保持する基板保持部２２が天井取付部２１に連設してある。基板保持部２２は、天井取付部２１と同心をなす環状を有しており、該天井取付部２１よりも引掛シーリングボディ２００の側に突設している。   The ceiling mounting part 21 is provided with a board holding part 22 for holding a power supply board and a control board, which will be described later, connected to the ceiling mounting part 21. The substrate holding part 22 has an annular shape that is concentric with the ceiling attaching part 21, and projects from the ceiling attaching part 21 toward the hooking ceiling body 200.

基板保持部２２には、環状の突条部２３が連設してある。該突条部２３は、天井取付部２１と略同一平面上にある。この突条部２３には、光源を保持する光源保持部２４が連設してある。光源保持部２４は、天井取付部２１と同心をなす環状を有しており、該天井取付部２１よりも引掛シーリングボディ２００の側に突設している。光源保持部２４の外周縁には、扁平な円筒状の周壁２５が立設してある。   An annular ridge 23 is connected to the substrate holder 22. The ridge portion 23 is on substantially the same plane as the ceiling mounting portion 21. A light source holding part 24 that holds a light source is connected to the protrusion 23. The light source holding part 24 has an annular shape that is concentric with the ceiling attaching part 21, and projects from the ceiling attaching part 21 toward the hooking ceiling body 200. A flat cylindrical peripheral wall 25 is erected on the outer peripheral edge of the light source holding part 24.

シャーシ２の光源保持部２４には、光源としての複数の照明モジュール３が設けてある。照明モジュール３は、図４に示すように、矩形板状のＬＥＤ基板３１と、該ＬＥＤ基板３１に実装されたＬＥＤ３２と、該ＬＥＤ３２の光出射方向に設けられた拡散レンズ３３と、入力端子及び出力端子とを備えてなる。照明モジュール３は、シャーシ２の光源保持部２４の一面２４ａに周方向に略等配をなして固定してある。アダプタ１が取付けられるシャーシ２の天井取付部２１に同心をなして光源保持部２４が環状に設けてあるから、該光源保持部２４に固定された光源である照明モジュール３は取付部であるアダプタ１の周囲に環状に配されることになる。即ち、アダプタ１及び照明モジュール３はシャーシ２の一面側に、面に沿った方向に分散して配置されることになり、被取付部材と直角をなす方向、換言すると被取付部材からの突設高さ方向には重なり合わないように配置される。   The light source holding part 24 of the chassis 2 is provided with a plurality of illumination modules 3 as light sources.

Further, an annular mounting seat 63b is formed on the outer peripheral edge portion of the top plate portion 63 so as to be recessed toward the fixing portion 61 with respect to the other portions. A signal receiver 55 that receives a signal from a signal transmitter such as a remote controller is provided inside the inner peripheral wall 62 of the power supply cover 6.

また、シャーシ２には、図６に示すごとく、直径の異なる環状の複数のクッション９１，９２，９３が設けてある。また、シャーシ２には、透光性カバーを押さえる複数のカバー押え９５が光源保持部２４の外縁部に取付けてある。カバー押え９５は、光源保持部２４の一面２４ａに取付けられるベース板部と、該ベース板部から直角をなす方向に延設された２つの腕部と、該腕部の端部から前記ベース板部に平行な方向に延設された係合爪部９５ａとを有している。   As shown in FIG. 6, the chassis 2 is provided with a plurality of annular cushions 91, 92, 93 having different diameters. In addition, a plurality of cover retainers 95 that hold the light-transmitting cover are attached to the chassis 2 at the outer edge portion of the light source holding portion 24. The cover presser 95 includes a base plate portion attached to the one surface 24a of the light source holding portion 24, two arm portions extending in a direction perpendicular to the base plate portion, and the base plate from the end portion of the arm portion. And an engaging claw portion 95a extending in a direction parallel to the portion.

このように照明モジュール３、電源基板４、制御基板５及び電源カバー６が取付けられたシャーシ２に、光源であるＬＥＤ３２からの光を透過する透光性カバー７が設けてある。透光性カバー７は、電源カバー６に固定される固定部７１と、該固定部７１に連設された幅広の環状部７２と、該環状部７２の外周縁から直交する方向に延設された側面部７３と、該側面部７３から環状部７２と鋭角をなす方向に延設された背面部７４と、該背面部７４に連設され、シャーシ２に係合する係合部７５とを有している。   Thus, the translucent cover 7 which permeate | transmits the light from LED32 which is a light source is provided in the chassis 2 with which the illumination module 3, the power supply board 4, the control board 5, and the power supply cover 6 were attached. The translucent cover 7 extends in a direction orthogonal to the fixing portion 71 fixed to the power source cover 6, a wide annular portion 72 provided continuously to the fixing portion 71, and the outer peripheral edge of the annular portion 72. A side surface portion 73, a back surface portion 74 extending from the side surface portion 73 in a direction that forms an acute angle with the annular portion 72, and an engagement portion 75 that is connected to the back surface portion 74 and engages with the chassis 2. Have.

透光性カバー７は、係合部７５をシャーシ２に取付けられたカバー押え９５の係合爪部９５ａに係合させて保持した状態にて、電源カバー６の天板部６３の取付座６３ｂ及び透光性カバー７の固定部７１に設けられたネジ用穴にネジを螺合することにより固定される。このように透光性カバー７、電源カバー６の外周壁６４及びシャーシ２により形成される空洞内に光源である照明モジュール３が収容されることになるから、電源部と照明モジュール３とを別室になるように分けて、照明モジュール３部分のみを密閉することが可能となる。電源カバー６の外周壁６４が光源と電源部との間を仕切る仕切枠を兼ねている。   The translucent cover 7 is attached to the mounting seat 63b of the top plate portion 63 of the power source cover 6 in a state where the engaging portion 75 is held by being engaged with the engaging claw portion 95a of the cover presser 95 attached to the chassis 2. And it fixes by screwing a screw in the screw hole provided in the fixing | fixed part 71 of the translucent cover 7. FIG. Thus, since the illumination module 3 which is a light source is accommodated in the cavity formed by the translucent cover 7, the outer peripheral wall 64 of the power supply cover 6, and the chassis 2, the power supply unit and the illumination module 3 are separated from each other. Thus, only the illumination module 3 portion can be sealed. The outer peripheral wall 64 of the power supply cover 6 also serves as a partition frame that partitions between the light source and the power supply unit.

以上のように組み立てられた照明装置本体をアダプタ１に取付け、アダプタ１のコネクタ１５と電源部にその一端が接続されたコネクタ４５とを接続した後、センタカバー８を照明装置本体に取付ける。センタカバー８は、緩やかに凸に湾曲した円板状を有している。センタカバー８の内側には複数の固定バネ８１が設けてある。センタカバー８は、固定バネ８１を電源カバー６の天板部６３に設けられた係合穴６３ａに係合することにより、電源カバー６に保持される。照明装置本体の被取付部材への取付け及び取外しは、このセンタカバー６を取外すことにより行うことができ、透光性カバー７等を取外す必要がないから光源部分の密閉は維持される。   The lighting device body assembled as described above is attached to the adapter 1, and after connecting the connector 15 of the adapter 1 and the connector 45 having one end connected to the power supply unit, the center cover 8 is attached to the lighting device body. The center cover 8 has a disk shape that is gently convexly curved. A plurality of fixing springs 81 are provided inside the center cover 8. The center cover 8 is held by the power supply cover 6 by engaging the fixing spring 81 with an engagement hole 63 a provided in the top plate portion 63 of the power supply cover 6. The illuminating device main body can be attached to and detached from the attached member by removing the center cover 6. Since it is not necessary to remove the translucent cover 7 and the like, the light source portion is kept sealed.

図７は、実施の形態１に係る照明装置１００の制御系の構成を示すブロック図である。電源部４１は、アダプタ１及び引掛シーリングボディ２００を介してＡＣ電源２１０に接続される。なお、電源部４１は、電源基板４、及び該電源基板４に実装され、ＡＣ電源から供給された電流を整流する整流回路、整流された電圧を所定の電圧に変換するトランス、一定電流を供給する定電流供給回路等の電子部品を有してなり、前述したように、照明装置１００のシャーシ２の基板保持部２２に設けてある。   FIG. 7 is a block diagram illustrating a configuration of a control system of lighting apparatus 100 according to Embodiment 1. The power supply unit 41 is connected to the AC power supply 210 via the adapter 1 and the hooking sealing body 200. The power supply unit 41 is mounted on the power supply board 4, the rectifier circuit that rectifies the current supplied from the AC power supply, the transformer that converts the rectified voltage into a predetermined voltage, and supplies a constant current. As described above, it is provided on the substrate holding portion 22 of the chassis 2 of the lighting device 100.

電源部４１には、同様にシャーシ２の基板保持部２２に設けられた制御基板５及び該制御基板５に実装された電子部品を有してなる調光回路部５２が接続してあり、電源部４１は、調光回路部５２に所定電圧の電力を供給する。   Similarly, the power supply unit 41 is connected to a control board 5 provided on the board holding unit 22 of the chassis 2 and a dimming circuit unit 52 having electronic components mounted on the control board 5. The unit 41 supplies power of a predetermined voltage to the dimming circuit unit 52.

調光回路部５２には、前述した如くシャーシ２の光源保持部２４に設けられた複数の照明モジュール３が接続してある。また、調光回路部５２には、シャーシ２の基板保持部２２に設けられた制御基板５及び該制御基板５に実装された電子部品を有してなる制御部５１が接続してある。制御部５１は、内部バスにより相互に接続されたＣＰＵ及び記憶素子を備えたマイクロコンピュータであり、記憶素子に記憶された制御プログラムに従うＣＰＵの動作により照明装置の各構成部の制御を行うように構成してある。   As described above, a plurality of illumination modules 3 provided in the light source holding unit 24 of the chassis 2 are connected to the dimming circuit unit 52. The light control circuit unit 52 is connected to a control unit 5 provided on the substrate holding unit 22 of the chassis 2 and a control unit 51 having electronic components mounted on the control substrate 5. The control unit 51 is a microcomputer including a CPU and a storage element connected to each other via an internal bus, and controls each component of the lighting device by the operation of the CPU according to a control program stored in the storage element. It is configured.

制御部５１には、照明装置１００内の適宜位置に設けられた操作部５６、リモートコントローラ等の信号送信部１０１からの赤外線を受光する受光部である信号受信部５５が接続してある。操作部５６、信号送信部１０１は、例えば、点灯／消灯する操作を受け付ける電源スイッチ、明るさの設定操作を受け付けるスイッチ等を有しており、制御部５１に操作に応じた信号を与える。   The control unit 51 is connected to an operation unit 56 provided at an appropriate position in the illumination device 100 and a signal receiving unit 55 that is a light receiving unit that receives infrared rays from the signal transmission unit 101 such as a remote controller. The operation unit 56 and the signal transmission unit 101 include, for example, a power switch that accepts an operation to turn on / off, a switch that accepts a brightness setting operation, and the like, and gives a signal corresponding to the operation to the control unit 51.

制御部５１は、記憶素子に記憶されたプログラムに従って、信号受信部５５が受信した信号送信部１０１からの信号及び操作部５６からの信号に基づいて、調光回路部５２に制御信号を与える。   The control unit 51 gives a control signal to the dimming circuit unit 52 based on the signal from the signal transmission unit 101 received by the signal reception unit 55 and the signal from the operation unit 56 according to the program stored in the storage element.

調光回路部５２は、スイッチング素子等を備え、制御部５１により与えられた制御信号に応じてスイッチング素子を開閉するように構成してある。このスイッチング素子の開閉動作に応じて、一定電流が照明モジュール３に供給され、照明モジュール３は所定の明るさにて点灯する。   The dimming circuit unit 52 includes a switching element and the like, and is configured to open and close the switching element in accordance with a control signal given by the control unit 51. A constant current is supplied to the lighting module 3 according to the opening / closing operation of the switching element, and the lighting module 3 is lit at a predetermined brightness.

以上のように構成された照明装置１００においては、取付部であるアダプタ１の周囲に電源基板４（電源基板４を備える電源部４１）が配してあり、電源基板４の周囲に照明モジュール３が配してあるから、アダプタ１、電源部４１及び照明モジュール３が被取付部材と直角をなす方向、換言すると被取付部材からの突設高さ方向には重なり合わないように配置される。この結果、被取付部材からのアダプタ１、電源部４１及び照明モジュール３の突設高さを低減することができ、照明装置１００を薄型化することができる。そして、板状をなすシャーシ２の一面側に、アダプタ１、電源部４１及び照明モジュール３が重なり合わないように配してあるから、天井等の被取付部材からの照明装置１００の突設高さを更に低減することができ、照明装置１００を更に薄型化することができる。   In the lighting device 100 configured as described above, the power supply board 4 (the power supply section 41 including the power supply board 4) is arranged around the adapter 1 that is the mounting portion, and the illumination module 3 is provided around the power supply board 4. Therefore, the adapter 1, the power source 41, and the illumination module 3 are arranged so as not to overlap in the direction perpendicular to the attached member, in other words, in the protruding height direction from the attached member. As a result, the protruding height of the adapter 1, the power source 41, and the illumination module 3 from the attached member can be reduced, and the illumination device 100 can be thinned. And since it arrange | positions so that the adapter 1, the power supply part 41, and the illumination module 3 may not overlap on the one surface side of the chassis 2 which makes plate shape, the protrusion height of the illuminating device 100 from to-be-attached members, such as a ceiling. Therefore, the lighting device 100 can be further reduced in thickness.

また、実施の形態１に係る照明装置１００においては、電源部４１の周りに設けられた電源カバー６の外周壁６４により、電源部４１と照明モジュール３との間が仕切られ、透光性カバー７、電源カバー６の外周壁６４及びシャーシ２により形成される空洞内に照明モジュール３が収容してある。このように電源部４１と照明モジュール３とを別室に分けて配置しているから、照明モジュール３のみを密閉することが可能となる。このように照明モジュール３と電源部４１とを電源カバー６の外周壁６４を仕切枠として別室に分けているから、例えば、照明装置１００の天井等の被取付部材への取付又は取外しをすべく、センタカバー８を取外したとき、電源部４１近傍が外部に露出した状態になるが、この場合においても、照明モジュール３部分の密閉状態を維持することが可能となる。この結果、照明モジュール３部分に虫等が侵入することを防止することができ、清掃が不要となり、使用者の利便に資する。また、密閉状態として、光源モジュール３を覆う透光性カバー７の脱着機構が不要となるから構造を簡略化することができ、コストを低減することができる。   Moreover, in the illuminating device 100 which concerns on Embodiment 1, between the power supply part 41 and the illumination module 3 is partitioned off by the outer peripheral wall 64 of the power supply cover 6 provided around the power supply part 41, and a translucent cover. 7. The illumination module 3 is accommodated in a cavity formed by the outer peripheral wall 64 of the power supply cover 6 and the chassis 2. Thus, since the power supply unit 41 and the illumination module 3 are arranged separately in separate rooms, only the illumination module 3 can be sealed. As described above, the illumination module 3 and the power supply unit 41 are divided into separate rooms using the outer peripheral wall 64 of the power supply cover 6 as a partition frame. For example, the illumination device 100 should be attached to or detached from the attached member such as the ceiling. When the center cover 8 is removed, the vicinity of the power supply unit 41 is exposed to the outside. Even in this case, the sealed state of the illumination module 3 can be maintained. As a result, it is possible to prevent insects and the like from entering the illumination module 3 portion, and cleaning is unnecessary, which contributes to the convenience of the user. Further, since the sealing mechanism does not require a detaching mechanism for the translucent cover 7 that covers the light source module 3, the structure can be simplified and the cost can be reduced.

また、熱伝導体の電源カバー６をシャーシ２に固定して熱的に接続してあるから、照明モジュール３、電源部４１等により発生した熱がシャーシ２に伝達され、シャーシ２に伝達された熱が、電源カバー６から照明装置１００のセンタカバー８の側に伝達されるから、照明装置１００の周囲の空気へ放散することができる。   In addition, since the heat conductor power supply cover 6 is fixed and thermally connected to the chassis 2, the heat generated by the lighting module 3, the power supply unit 41, and the like is transmitted to the chassis 2 and transmitted to the chassis 2. Since heat is transmitted from the power source cover 6 to the center cover 8 side of the lighting device 100, the heat can be dissipated to the air around the lighting device 100.

そして、光源にＬＥＤ３２を用いている。ＬＥＤ３２は、小型の光源であるから、光源部分の厚みを薄くすることができ、天井等の被取付部材からの照明装置の突設高さを低減することができ、照明装置を薄型化することができる。また、蛍光管と異なり、ＬＥＤ３２を用いることにより、透光性カバー７の環状部７２を平らにすることができ、光源部分の厚みを薄くすることができる。そして、拡散レンズ３３をＬＥＤ３２の光出射方向に設けているから、ＬＥＤ３２からの光は、拡散レンズ３３によって広範囲に拡散することができ、透光性カバー７とＬＥＤ３２との間隔を小さくしても、均一な発光が可能となる。従って、光源にＬＥＤ３２を用いることにより、均一な発光を確保しつつ、照明装置１００を薄型化することが可能となる。また、光源の形状が浮き出ることなく、均一な発光をさせることができるから、デザイン性の良い照明装置１００を提供することができる。   And LED32 is used for the light source. Since the LED 32 is a small light source, the thickness of the light source portion can be reduced, the protruding height of the lighting device from the mounted member such as the ceiling can be reduced, and the lighting device can be thinned. Can do. Further, unlike the fluorescent tube, by using the LED 32, the annular portion 72 of the translucent cover 7 can be flattened, and the thickness of the light source portion can be reduced. Since the diffusion lens 33 is provided in the light emitting direction of the LED 32, the light from the LED 32 can be diffused over a wide range by the diffusion lens 33, and even if the distance between the translucent cover 7 and the LED 32 is reduced. Uniform light emission is possible. Therefore, by using the LED 32 as the light source, it is possible to reduce the thickness of the lighting device 100 while ensuring uniform light emission. In addition, since the light source can be uniformly emitted without the shape of the light source emerging, the lighting device 100 with good design can be provided.

なお、本実施の形態においては、照明モジュール３と電源部４１とを仕切る仕切枠を電源カバー６が兼ねているが、これに限定されず、仕切枠を電源カバーとは別に設けてもよい。   In the present embodiment, the power supply cover 6 also serves as a partition frame for partitioning the illumination module 3 and the power supply unit 41. However, the present invention is not limited to this, and the partition frame may be provided separately from the power supply cover.

（実施の形態２）
図８は、実施の形態２に係る照明装置１１０の主要部の配置を示す説明図である。なお、図８においては、主要部の配置を簡略化して記載している。図９は、実施の形態２に係る照明装置１１０の制御系の構成を示すブロック図である。実施の形態２に係る照明装置１１０においては、照明モジュール３に加えて、複数の常夜灯モジュール３５を備えている。常夜灯モジュール３５は、矩形板状をなす基板３６と、該基板３６に実装された常夜灯ＬＥＤ３７と、該常夜灯ＬＥＤ３７に一定電流を供給する定電流ＩＣ３８とを備えてなる。この常夜灯モジュール３５は、図８に示すように、シャーシ２の一面側の外周縁部に周方向に略３等配をなして取付けてある。そして、常夜灯モジュール３５は、図９に示すように、調光回路部５２に接続してある。調光回路部５２は、制御部５１により与えられた制御信号に応じて、一定電流が常夜灯モジュール３５に供給される。その他の構成は、図４及び図７に示す実施の形態１と同様であるため、対応する構成部材に図４及び７と同一の参照符号を付して、その構成の詳細な説明を省略する。 (Embodiment 2)
FIG. 8 is an explanatory diagram showing an arrangement of main parts of the illumination device 110 according to the second embodiment. In addition, in FIG. 8, arrangement | positioning of the principal part is simplified and described. FIG. 9 is a block diagram illustrating a configuration of a control system of lighting apparatus 110 according to Embodiment 2. The lighting device 110 according to the second embodiment includes a plurality of nightlight modules 35 in addition to the lighting module 3. The nightlight module 35 includes a board 36 having a rectangular plate shape, an nightlight LED 37 mounted on the board 36, and a constant current IC 38 that supplies a constant current to the nightlight LED 37. As shown in FIG. 8, the nightlight module 35 is attached to the outer peripheral edge portion on the one surface side of the chassis 2 so as to have a substantially equal distribution in the circumferential direction. And the nightlight module 35 is connected to the light control circuit part 52, as shown in FIG. The dimming circuit unit 52 is supplied with a constant current to the nightlight module 35 in accordance with the control signal given by the control unit 51. Since other configurations are the same as those of the first embodiment shown in FIGS. 4 and 7, the same reference numerals as those in FIGS. .

本実施の形態に係る照明装置１１０においては、照明モジュール３と常夜灯モジュール３５とを別体に設けて、別途配置してある。常夜灯モジュール３５を照明モジュール３と別体に設けているから、常夜灯モジュール３５の位置及び／又は数を変えた照明装置を提供することが容易となる。即ち、例えば、購入時に使用者の好みを聞いて、照明モジュール３の配置を変更することなく、常夜灯モジュール３５の位置及び／又は数を使用者の好みになるように施工業者により設置するようにすることが可能となる。   In the illumination device 110 according to the present embodiment, the illumination module 3 and the nightlight module 35 are provided separately and separately arranged. Since the nightlight module 35 is provided separately from the lighting module 3, it is easy to provide an illumination device in which the position and / or number of the nightlight modules 35 are changed. That is, for example, after listening to the user's preference at the time of purchase, the position and / or number of the nightlight module 35 is installed by the contractor so as to meet the user's preference without changing the arrangement of the lighting module 3. It becomes possible to do.

なお、本実施の形態の照明装置１１０のように、アダプタ１や電源部４１を照明装置の中央部に配置し、それらの周囲に仕切枠を挟んで常夜灯モジュールを設けているような場合において、常夜灯モジュールが１つである或いは複数の常夜灯モジュールが偏った位置に集中して設けられていると、常夜灯モジュールからの光が電源回路や仕切枠等によって遮られてしまい、室内の一部しか照明できないという問題がある。特に常夜灯の光源としてＬＥＤを用いた場合には、指向性が強いので、常夜灯モジュールからの光が十分に拡散されず、上記問題が顕著なものであった。   In addition, like the lighting device 110 of the present embodiment, in the case where the adapter 1 and the power supply unit 41 are arranged in the center of the lighting device and a nightlight module is provided around the partition frame, If there is only one nightlight module or multiple nightlight modules are concentrated in a biased position, the light from the nightlight module is blocked by the power supply circuit or partition frame, and only a part of the room is illuminated. There is a problem that you can not. In particular, when an LED is used as the light source of the nightlight, the directivity is strong, and thus the light from the nightlight module is not sufficiently diffused, and the above problem is remarkable.

しかし、本実施の形態では、３つの常夜灯モジュールを周方向に略３等配をなして取付けていることによって、たとえ個々の常夜灯モジュールからの光が電源回路や仕切枠等で遮られたとしても、複数の常夜灯モジュールで室内全体を照明することが可能である。なお、常夜灯モジュールは３つの限られず、照明装置の大きさや形状に応じて、複数個の常夜灯モジュールをアダプタや電源部との仕切枠の周囲に等間隔にバランス良く配置させることによって、前記効果を得ることは可能となる。   However, in this embodiment, even if the three nightlight modules are mounted in a substantially three-way arrangement in the circumferential direction, even if light from each nightlight module is blocked by the power supply circuit, the partition frame, etc. It is possible to illuminate the entire room with a plurality of nightlight modules. The number of nightlight modules is not limited to three. Depending on the size and shape of the lighting device, a plurality of nightlight modules can be arranged at equal intervals around the partition frame with the adapter and the power supply unit in a balanced manner. It is possible to obtain.

また、各常夜灯モジュール３５に定電流ＩＣ３８を設けているから、常夜灯ＬＥＤを好みに応じて電球色、アンバー色のＬＥＤに変更したり、常夜灯モジュール３５当たりの常夜灯ＬＥＤの数を変更したりした場合にも、各常夜灯ＬＥＤに所定電流を供給することができるから、使用者の好みに応じた照明を提供することが可能となる。また、常夜灯モジュール３５の明るさを調光回路部５２により調節可能なように構成することも可能である。   In addition, since the constant current IC 38 is provided in each nightlight module 35, the nightlight LED is changed to a light bulb color or amber color LED according to the preference, or the number of nightlight LEDs per nightlight module 35 is changed. In addition, since a predetermined current can be supplied to each nightlight LED, it is possible to provide illumination according to the user's preference. Further, the brightness of the nightlight module 35 can be adjusted by the dimming circuit unit 52.

図１１は、実施の形態４に係る照明装置１３０の主要部の配置を示す説明図である。図１２は、実施の形態４に係る照明装置１３０の主要部の配置を示す模式的部分断面図である。なお、図１２においては、主要部の配置を簡略化して記載している。図１３は、実施の形態４に係る照明装置１３０の点灯状態の説明図である。実施の形態４に係る照明装置１３０において、常夜灯モジュール３５は、図１１及び図１２に示すように、電源カバー６の天板部６３に周方向に略３等配をなして取付けてある。なお、センタカバー８ａは、透光性カバー７と同様の透光性の材料によって形成してある。その他の構成は、図４及び図５に示す実施の形態１と同様であるため、対応する構成部材に図４及び図５と同一の参照符号を付して、その構成の詳細な説明を省略する。 (Embodiment 4)
FIG. 11 is an explanatory diagram showing an arrangement of main parts of the illumination device 130 according to the fourth embodiment. FIG. 12 is a schematic partial cross-sectional view showing the arrangement of the main parts of lighting apparatus 130 according to Embodiment 4. In FIG. 12, the arrangement of the main parts is shown in a simplified manner. FIG. 13 is an explanatory diagram of a lighting state of the illumination device 130 according to the fourth embodiment. In the illuminating device 130 according to Embodiment 4, the nightlight module 35 is attached to the top plate portion 63 of the power supply cover 6 at a substantially equal distribution in the circumferential direction as shown in FIGS. The center cover 8a is made of a light-transmitting material similar to the light-transmitting cover 7. The other configuration is the same as that of the first embodiment shown in FIGS. 4 and 5, and therefore, the same reference numerals as those in FIGS. To do.

実施の形態４に係る照明装置１３０は、照明モジュール３と常夜灯モジュール３５の配置をシャーシ２の光源保持部２４と電源カバー６とに分けて配置している。この結果、通常の生活時間帯に生活空間を明るく照らすべく照明する主照明の際に、照明モジュール３を点灯したときに、図１３に示すように、透光性カバー７の部分が明るくなる。一方、夜間等に足元を薄明るく照らすべく照明する常夜灯照明の際に、常夜灯モジュール３５を点灯したときには、図１２に示すように、常夜灯ＬＥＤ３７からの光はセンタカバー８ａを透過するから、図１３に示すように、センタカバー８ａの部分が明るくなる。このように、主照明と常夜灯照明の場合に、発光部分を変えることができる。   In the illumination device 130 according to Embodiment 4, the arrangement of the illumination module 3 and the nightlight module 35 is divided into the light source holding part 24 and the power supply cover 6 of the chassis 2. As a result, when the illumination module 3 is turned on during the main illumination that illuminates the living space brightly during a normal life time zone, the portion of the translucent cover 7 becomes bright as shown in FIG. On the other hand, when the nightlight module 35 is turned on during nightlight illumination to illuminate the feet lightly at night or the like, the light from the nightlight LED 37 passes through the center cover 8a as shown in FIG. As shown, the center cover 8a is brightened. Thus, the light emission part can be changed in the case of main illumination and nightlight illumination.

（実施の形態５）
図１４は、実施の形態５に係る照明装置１４０の主要部の配置を示す模式的部分断面図である。図１５は、実施の形態５に係る照明装置１４０の点灯状態の説明図である。実施の形態５に係る照明装置１４０においては、センタカバー８ｂの材料を不透光性の樹脂製とし、センタカバー８ｂの周壁部に周方向に略等配をなして複数の格子穴８５を設けている。その他の構成は、図１２及び図１３に示す実施の形態４と同様であるため、対応する構成部材に図１２及び図１３と同一の参照符号を付して、その構成の詳細な説明を省略する。 (Embodiment 5)
FIG. 14 is a schematic partial cross-sectional view showing the arrangement of main parts of lighting apparatus 140 according to Embodiment 5. FIG. 15 is an explanatory diagram of a lighting state of the illumination device 140 according to Embodiment 5. In the illuminating device 140 according to Embodiment 5, the material of the center cover 8b is made of a non-translucent resin, and a plurality of lattice holes 85 are provided in the circumferential wall portion of the center cover 8b so as to be substantially even in the circumferential direction. ing. The other configuration is the same as that of the fourth embodiment shown in FIGS. 12 and 13, and therefore, the same reference numerals as those in FIGS. To do.

実施の形態５に係る照明装置１４０は、センタカバー８ｂに格子穴８５を設けて、図１４及び図１５に示すように、格子穴８５から常夜灯モジュール３５の常夜灯ＬＥＤ３７からの光が出射するようにしてある。この結果、照明装置１４０の主照明の光出射方向ではく、主照明の照明モジュール３の光出射方向に略直交する方向、側方に常夜灯モジュール３５からの光が出射することになる。例えば、照明装置１４０を天井に設置した場合、常夜灯ＬＥＤ３７の光により、天井及び壁が照らされることなる。よって、常夜灯の光は柔らかい間接照明として提供することができる。また、センタカバー８ｂに格子穴８５を設けているから、電源部４１等により発生した熱を照明装置１４０の外部の空気に放散することが可能となる。   The illuminating device 140 according to Embodiment 5 is provided with a lattice hole 85 in the center cover 8b so that light from the nightlight LED 37 of the nightlight module 35 is emitted from the lattice hole 85 as shown in FIGS. It is. As a result, the light from the nightlight module 35 is emitted in a direction substantially perpendicular to the light emission direction of the illumination module 3 of the main illumination, not in the light emission direction of the main illumination of the illumination device 140. For example, when the lighting device 140 is installed on the ceiling, the ceiling and the wall are illuminated by the light of the nightlight LED 37. Therefore, the nightlight light can be provided as soft indirect illumination. In addition, since the lattice holes 85 are provided in the center cover 8b, it is possible to dissipate heat generated by the power supply unit 41 and the like to the air outside the lighting device 140.

なお、以上の実施の形態２乃至５に係る照明装置においては、常夜灯モジュール３５の数を３つとしているが、３つに限定されず、１つでもよいし、２つまたは４以上であってもよい。即ち、使用者の好みに応じて選択されればよい。   In the lighting devices according to Embodiments 2 to 5, the number of nightlight modules 35 is three, but is not limited to three, and may be one, two, or four or more.
