図１は、本実施の形態に係る照明装置１０を示す図である。図１に示す照明装置１０は、主に商業空間の屋外照明や屋内照明といった電飾に用いられる。図１に示すように、照明装置１０は、天井や壁などに固定される配線ダクトレール１２と、配線ダクトレール１２に装着して用いられる灯具１４と、を備える。   FIG. 1 is a diagram showing a lighting device 10 according to the present embodiment. The illuminating device 10 shown in FIG. 1 is mainly used for electrical decoration such as outdoor lighting and indoor lighting in a commercial space. As shown in FIG. 1, the lighting device 10 includes a wiring duct rail 12 that is fixed to a ceiling, a wall, and the like, and a lamp 14 that is used by being attached to the wiring duct rail 12.

灯具１４は、配線ダクトレール１２にスライド自在に装着されており、ユーザは、配線ダクトレール１２の自由な位置に灯具１４を装着して使用することができる。なお、図１には、配線ダクトレール１２に対して１つの灯具１４が装着されている様子を示しているが、配線ダクトレール１２には、複数の灯具１４を装着することも可能である。   The lamp 14 is slidably mounted on the wiring duct rail 12, and the user can use the lamp 14 by mounting the lamp 14 at a free position on the wiring duct rail 12. Although FIG. 1 shows a state where one lamp 14 is attached to the wiring duct rail 12, a plurality of lamps 14 can be attached to the wiring duct rail 12.

図１に示すように、配線ダクトレール１２は、カーテンレール状に形成される。配線ダクトレール１２は、樹脂にて一体成形されてもよい。この場合、配線ダクトレールを軽量化できる。また、配線ダクトレール１２を樹脂にて一体成形した場合には、設置する場所に応じて容易に配線ダクトレール１２を任意の長さに加工することができる。配線ダクトレール１２は、例えば０．５ｍ〜１．５ｍ程度の長さに形成される。   As shown in FIG. 1, the wiring duct rail 12 is formed in a curtain rail shape. The wiring duct rail 12 may be integrally formed of resin. In this case, the wiring duct rail can be reduced in weight. In addition, when the wiring duct rail 12 is integrally formed of resin, the wiring duct rail 12 can be easily processed to an arbitrary length according to the installation location. The wiring duct rail 12 is formed with a length of about 0.5 m to 1.5 m, for example.

配線ダクトレール１２は、その底面部である基部１６に、赤色ＬＥＤ用導線２２ａ、緑色ＬＥＤ用導線２２ｂ、青色ＬＥＤ用導線２２ｃ、コモン用導線２２ｄを備える。以下では、適宜、赤色ＬＥＤ用導線２２ａ、緑色ＬＥＤ用導線２２ｂ、青色ＬＥＤ用導線２２ｃ、コモン用導線２２ｄを総称して「導線２２」と呼ぶ。   The wiring duct rail 12 includes a red LED lead wire 22a, a green LED lead wire 22b, a blue LED lead wire 22c, and a common lead wire 22d on the base 16 which is the bottom surface portion thereof. In the following description, the red LED conductor 22a, the green LED conductor 22b, the blue LED conductor 22c, and the common conductor 22d are collectively referred to as “conductor 22” as appropriate.

灯具１４は、図１に示すように、配線ダクトレール１２にスライド自在に係合するように形成された棒状の灯具である。配線ダクトレール１２は、例えば２０ｃｍ程度の長さに形成される。灯具１４には、ＲＧＢ（赤色、緑色、青色）３色のＬＥＤが搭載されており、３色のＬＥＤに印加される電圧を制御することにより、それぞれ異なる強さで発光させることができる。３色のＬＥＤの発光強度を調整することにより、フルカラー発光を実現できる。ＬＥＤが発光した光は、ＬＥＤ開口部３０から外部に放射される。   As shown in FIG. 1, the lamp 14 is a rod-shaped lamp formed so as to be slidably engaged with the wiring duct rail 12. The wiring duct rail 12 is formed to a length of about 20 cm, for example. The lamp 14 is equipped with LEDs of three colors RGB (red, green, blue), and can control the voltages applied to the three colors of LEDs to emit light with different intensities. Full color light emission can be realized by adjusting the light emission intensity of the three color LEDs. The light emitted from the LED is emitted from the LED opening 30 to the outside.

図２は、本実施の形態に係る配線ダクトレール１２の正面図である。図２に示すように、配線ダクトレール１２は、基部１６と、側部２０と、灯具係止部１８と、溝部２４と、導線２２と、を備える。   FIG. 2 is a front view of the wiring duct rail 12 according to the present embodiment. As shown in FIG. 2, the wiring duct rail 12 includes a base portion 16, a side portion 20, a lamp engaging portion 18, a groove portion 24, and a conductive wire 22.

基部１６は、配線ダクトレール１２の底面部に位置し、灯具１４に電力を供給するための導線２２を備える。配線ダクトレール１２は、基部１６の短手方向の両縁部から、一対の側部２０が上方に延設されている。側部２０の上端部には、灯具１４を係止するための灯具係止部１８が、内側に相対向するように延設されている。   The base portion 16 is located on the bottom surface portion of the wiring duct rail 12 and includes a conductive wire 22 for supplying power to the lamp 14. The wiring duct rail 12 has a pair of side portions 20 extending upward from both edges of the base portion 16 in the short direction. At the upper end portion of the side portion 20, a lamp locking portion 18 for locking the lamp 14 is extended so as to face the inside.

基部１６の上面には、導線２２を収容するための溝部２４が設けられる。本実施の形態に係る配線ダクトレール１２では、４本の導線２２を収容するために、４つの溝部２４が設けられている。４つの溝部２４は、配線ダクトレール１２の長手方向に沿って平行に、所定の間隔を有して設けられている。   On the upper surface of the base portion 16, a groove portion 24 for accommodating the conducting wire 22 is provided. In the wiring duct rail 12 according to the present embodiment, four groove portions 24 are provided in order to accommodate the four conductive wires 22. The four groove portions 24 are provided in parallel with the longitudinal direction of the wiring duct rail 12 with a predetermined interval.

図２に示すように、溝部２４は、基部１６の上面に開口する第１溝部２４ａと、第１溝部２４ａの下方に形成される第２溝部２４ｂと、を有して構成される。第１溝部２４ａは、断面視で幅Ｗａ、深さＤａの矩形状の溝である。第２溝部２４ｂは、断面視で幅Ｗｂ、深さＤｂの矩形状の溝である。   As shown in FIG. 2, the groove 24 includes a first groove 24 a that opens on the upper surface of the base 16 and a second groove 24 b that is formed below the first groove 24 a. The first groove portion 24a is a rectangular groove having a width Wa and a depth Da in a sectional view. The second groove portion 24b is a rectangular groove having a width Wb and a depth Db in a sectional view.

本実施の形態に係る配線ダクトレール１２において、第２溝部２４ｂの幅Ｗｂは、導線２２の直径Ｗｄより大きく形成される。これにより、第２溝部２４ｂに導線２２を収容することができる。さらに、基部１６上面における開口幅Ｗａは、導線２２の直径Ｗｄよりも小さく形成される。これにより、第２溝部２４ｂに収容された導線２２が、溝部２４の外部に外れることを防止できる。   In the wiring duct rail 12 according to the present embodiment, the width Wb of the second groove portion 24b is formed larger than the diameter Wd of the conducting wire 22. Thereby, the conducting wire 22 can be accommodated in the second groove portion 24b. Furthermore, the opening width Wa on the upper surface of the base portion 16 is formed smaller than the diameter Wd of the conducting wire 22. Thereby, it can prevent that the conducting wire 22 accommodated in the 2nd groove part 24b remove | deviates from the groove part 24 outside.

また、溝部２４は、第１溝部２４ａの幅Ｗａ、第２溝部２４ｂの深さＤｂ、導線２２の直径Ｗｄが、下記の（１）式を満たすように形成される。例えば、Ｗｄ＝１．２ｍｍ、Ｗａ＝１．０５ｍｍのとき、Ｄｂ≦０．８９ｍｍとなるように形成される。これにより、第１溝部２４ａの両下端部と、第２溝部２４ｂの底面とにより、導線２２を断面視で３点接触にて支持できる。   Further, the groove 24 is formed so that the width Wa of the first groove 24a, the depth Db of the second groove 24b, and the diameter Wd of the conducting wire 22 satisfy the following expression (1). For example, when Wd = 1.2 mm and Wa = 1.05 mm, Db ≦ 0.89 mm. Thereby, the conducting wire 22 can be supported in a three-point contact in a cross-sectional view by both lower ends of the first groove portion 24a and the bottom surface of the second groove portion 24b.

Figure 2007317575
Figure 2007317575

本実施の形態に係る配線ダクトレール１２において、溝部２４には、断面円形状の導線２２が収容保持される。図２に示すように、導線２２は、その中心軸が第２溝部２４ｂの内部に位置するように収容される。   In the wiring duct rail 12 according to the present embodiment, a conductive wire 22 having a circular cross section is accommodated and held in the groove 24. As shown in FIG. 2, the conducting wire 22 is accommodated so that the central axis thereof is located inside the second groove portion 24b.

ここで、配線ダクトレール１２が、レールの長手方向を軸としてねじれた場合について考察する。特に、基部１６、側部２０、灯具係止部１８を樹脂にて一体成形した場合には、金属で成形した場合よりも配線ダクトレール１２の剛性が低下するので、レールの長手方向を軸としてねじれが生じやすくなる。   Here, consider the case where the wiring duct rail 12 is twisted about the longitudinal direction of the rail. In particular, when the base portion 16, the side portion 20, and the lamp engaging portion 18 are integrally formed of resin, the rigidity of the wiring duct rail 12 is lower than that of metal, so the longitudinal direction of the rail is used as an axis. Twist is likely to occur.

配線ダクトレール１２がねじれた場合、導線２２も共にねじれ、溝部２４内を回転しようとする。導線が断面四角形状の場合、導線が回転しようとすると、導線は溝部による係止を解かれ、溝部から外れてしまう。本実施の形態に係る配線ダクトレール１２では、導線２２を断面円形状としたので、配線ダクトレール１２にねじれが生じた場合であっても、導線２２は、溝部２４内を回転することができ、溝部２４から導線２２が外れることを防止できる。   When the wiring duct rail 12 is twisted, the conductors 22 are twisted together and try to rotate in the groove 24. When the conducting wire has a quadrangular cross section, when the conducting wire tries to rotate, the conducting wire is unlocked by the groove and is detached from the groove. In the wiring duct rail 12 according to the present embodiment, since the conducting wire 22 has a circular cross section, the conducting wire 22 can rotate in the groove 24 even when the wiring duct rail 12 is twisted. Further, it is possible to prevent the lead wire 22 from being detached from the groove portion 24.

図２に示すように、本実施の形態に係る配線ダクトレール１２では、導線２２の中心軸は第２溝部２４ｂ内部に位置すると共に、導線２２の上端は第１溝部２４ａ内部に位置するように溝部２４が形成されている。このように、溝部２４は、導線２２が基部１６の上面から突出しないよう形成されることが好ましい。導線２２が基部１６の上面から突出しないように溝部２４を形成することによって、ユーザの手指が導線に触れ、感電することを防止できる。また、金属片などによる導線間の短絡を防止できる。   As shown in FIG. 2, in the wiring duct rail 12 according to the present embodiment, the central axis of the conducting wire 22 is located inside the second groove portion 24b, and the upper end of the conducting wire 22 is located inside the first groove portion 24a. A groove portion 24 is formed. Thus, the groove portion 24 is preferably formed so that the conductive wire 22 does not protrude from the upper surface of the base portion 16. By forming the groove portion 24 so that the conducting wire 22 does not protrude from the upper surface of the base portion 16, it is possible to prevent the user's fingers from touching the conducting wire and receiving an electric shock. Moreover, the short circuit between conducting wires by a metal piece etc. can be prevented.

また、上述したように、本実施の形態に係る配線ダクトレール１２では、第１溝部２４ａの両下端部と、第２溝部２４ｂの底面とにより、導線２２を断面視で３点接触にて収容保持している。この場合、導線２２の外周面が溝部２４の内壁面に面接触している場合よりも、導線２２が溝部２４内を回転しやすくなるので、より効果的に溝部２４から導線２２が外れることを防止できる。   Further, as described above, in the wiring duct rail 12 according to the present embodiment, the conductive wire 22 is accommodated in a three-point contact in a cross-sectional view by the both lower ends of the first groove 24a and the bottom surface of the second groove 24b. keeping. In this case, since the conducting wire 22 is easier to rotate in the groove portion 24 than when the outer peripheral surface of the conducting wire 22 is in surface contact with the inner wall surface of the groove portion 24, the conductor wire 22 is more effectively detached from the groove portion 24. Can be prevented.

基部１６、側部２０、灯具係止部１８を樹脂にて一体成形する場合、樹脂成形後に溝部２４に導線２２を嵌入することによって配線ダクトレール１２を製造する。基部１６、側部２０、灯具係止部１８を樹脂にて一体成形した場合には、樹脂の可撓性により、導線２２の大きさが多少の誤差を有していても、溝部２４に導線２２を嵌入することが可能となる。   When the base portion 16, the side portion 20, and the lamp engaging portion 18 are integrally formed of resin, the wiring duct rail 12 is manufactured by fitting the conductive wire 22 into the groove portion 24 after resin molding. When the base portion 16, the side portion 20, and the lamp engaging portion 18 are integrally formed of resin, even if the size of the conductor 22 has some error due to the flexibility of the resin, the conductor is connected to the groove 24. 22 can be inserted.

図３は、図１に示す灯具１４のＸ−Ｘ断面図である。図３に示すように、灯具１４は、上ケース３２と、下ケース３４と、を備える。上ケース３２と、下ケース３４は、互いに係合した状態で間に中空部が形成されるように接合される。上ケース３２と下ケース３４の間に形成される中空部には、赤色ＬＥＤ４２ａ、緑色ＬＥＤ４２ｂ、青色ＬＥＤ４２ｃが実装された基板４０が設けられる。基板４０は、上ケース３２と下ケース３４によって狭持されることによって固定される。   FIG. 3 is a sectional view taken along line XX of the lamp 14 shown in FIG. As shown in FIG. 3, the lamp 14 includes an upper case 32 and a lower case 34. The upper case 32 and the lower case 34 are joined so that a hollow portion is formed between them when engaged with each other. A hollow portion formed between the upper case 32 and the lower case 34 is provided with a substrate 40 on which red LEDs 42a, green LEDs 42b, and blue LEDs 42c are mounted. The substrate 40 is fixed by being sandwiched between the upper case 32 and the lower case 34.

灯具１４が配線ダクトレール１２に装着されると、第１赤色用接点ばね３６ａ、第２赤色用接点ばね３７ａは、配線ダクトレール１２の赤色ＬＥＤ用導線２２ａと電気的に接続される。第１緑色用接点ばね３６ｂ、第２緑色用接点ばね３７ｂは、配線ダクトレール１２の緑色ＬＥＤ用導線２２ｂと電気的に接続される。第１青色用接点ばね３６ｃ、第２青色用接点ばね３７ｃは、配線ダクトレール１２の青色ＬＥＤ用導線２２ｃと電気的に接続される。第１コモン用接点ばね３６ｄ、第２コモン用接点ばね３７ｄは、配線ダクトレール１２のコモン用導線２２ｄと電気的に接続される。   When the lamp 14 is mounted on the wiring duct rail 12, the first red contact spring 36 a and the second red contact spring 37 a are electrically connected to the red LED conductor 22 a of the wiring duct rail 12.

以上のように構成された照明装置１０の動作について説明する。配線ダクトレール１２の４本の導線２２は、それぞれ一端が図示しない制御装置に接続される。   The operation of the illumination device 10 configured as described above will be described. One end of each of the four conducting wires 22 of the wiring duct rail 12 is connected to a control device (not shown).

制御装置により、コモン用導線２２ｄの電位は所定の電位に設定される。これにより、灯具１４のコモン線５０も所定の電位となる。この状態で、制御装置により、配線ダクトレール１２の赤色ＬＥＤ用導線２２ａ、緑色ＬＥＤ用導線２２ｂ、青色ＬＥＤ用導線２２ｃの電位をコモン用導線２２ｄの電位よりも低い電位に設定すると、灯具１４のコモン線５０と、赤色用電力供給線５２、緑色用電力供給線５４、青色用電力供給線５６との間にそれぞれ電位差が生じるので、ＬＥＤを発光させることができる。赤色用電力供給線５２、緑色用電力供給線５４、青色用電力供給線５６の電位は、赤色ＬＥＤ４２ａ、緑色ＬＥＤ４２ｂ、青色ＬＥＤ４２ｃによる電圧降下分を考慮して設定する。   The potential of the common conducting wire 22d is set to a predetermined potential by the control device. As a result, the common line 50 of the lamp 14 also has a predetermined potential. In this state, when the potential of the red LED lead wire 22a, the green LED lead wire 22b, and the blue LED lead wire 22c of the wiring duct rail 12 is set to a potential lower than the potential of the common lead wire 22d by the control device, the lamp 14 Since a potential difference is generated between the common line 50, the red power supply line 52, the green power supply line 54, and the blue power supply line 56, the LED can emit light. The potentials of the red power supply line 52, the green power supply line 54, and the blue power supply line 56 are set in consideration of the voltage drop due to the red LED 42a, the green LED 42b, and the blue LED 42c.

制御装置によって赤色ＬＥＤ用導線２２ａ、緑色ＬＥＤ用導線２２ｂ、青色ＬＥＤ用導線２２ｃの電位をそれぞれ制御することにより、赤色ＬＥＤ４２ａ、緑色ＬＥＤ４２ｂ、青色ＬＥＤ４２ｃの発光強度を制御することができるので、フルカラー発光が可能な照明装置を実現できる。   The control device can control the light emission intensity of the red LED 42a, the green LED 42b, and the blue LED 42c by controlling the potentials of the red LED lead wire 22a, the green LED lead wire 22b, and the blue LED lead wire 22c. Can be realized.

The 1st wiring duct rail 60 and the 2nd wiring duct rail 62 are fixed to a wall surface or a ceiling using a double-sided tape, for example.

照明装置１００において、第１灯具６４は第１配線ダクトレール６０に装着され、第３灯具６８は第２配線ダクトレール６２に装着されている。第２灯具６６は、灯具の半分が第１配線ダクトレール６０に装着され、残りの半分が第２配線ダクトレール６２に装着されている。すなわち、第２灯具６６の第１赤色用接点ばね、第１緑色用接点ばね、第１青色用接点ばね、第１コモン用接点ばねは、第１配線ダクトレール６０の赤色ＬＥＤ用導線、緑色ＬＥＤ用導線、青色ＬＥＤ用導線、コモン用導線にそれぞれ電気的に接続される。また、第２灯具６６の第２赤色用接点ばね、第２緑色用接点ばね、第２青色用接点ばね、第２コモン用接点ばねは、第２配線ダクトレール６２の赤色ＬＥＤ用導線、緑色ＬＥＤ用導線、青色ＬＥＤ用導線、コモン用導線にそれぞれ電気的に接続される。   In the lighting device 100, the first lamp 64 is mounted on the first wiring duct rail 60, and the third lamp 68 is mounted on the second wiring duct rail 62. In the second lamp 66, half of the lamp is mounted on the first wiring duct rail 60 and the other half is mounted on the second wiring duct rail 62.

図５に示すように第１配線ダクトレール６０と第２配線ダクトレール６２にまたがって第２灯具６６を装着した場合、第１配線ダクトレール６０の赤色ＬＥＤ用導線は、第２灯具６６の第１赤色用接点ばね、赤色用電力供給線、第２赤色用接点ばねを介して第２配線ダクトレール６２の赤色ＬＥＤ用導線に電気的に接続される。また、第１配線ダクトレール６０の緑色ＬＥＤ用導線は、第２灯具６６の第１緑色用接点ばね、緑色用電力供給線、第２緑色用接点ばねを介して第２配線ダクトレール６２の緑色ＬＥＤ用導線に接続される。また、第１配線ダクトレール６０の青色ＬＥＤ用導線は、第２灯具６６の第１青色用接点ばね、青色用電力供給線、第２青色用接点ばねを介して第２配線ダクトレール６２の青色ＬＥＤ用導線に接続される。また、第１配線ダクトレール６０のコモン用導線は、第２灯具６６の第１コモン用接点ばね、コモン線、第２コモン用接点ばねを介してコモン用導線に接続される。以上のように、照明装置１００において、第２灯具６６は、第１配線ダクトレール６０と第２配線ダクトレール６２とを電気的に接続する機能を有している。   As shown in FIG. 5, when the second lamp 66 is mounted across the first wiring duct rail 60 and the second wiring duct rail 62, the red LED conductor of the first wiring duct rail 60 is connected to the second lamp 66. The first red contact spring, the red power supply line, and the second red contact spring are electrically connected to the red LED lead of the second wiring duct rail 62. The green LED lead wire of the first wiring duct rail 60 is connected to the green color of the second wiring duct rail 62 via the first green contact spring, the green power supply line, and the second green contact spring of the second lamp 66.

Also, the blue LED lead wire of the first wiring duct rail 60 is blue on the second wiring duct rail 62 via the first blue contact spring, the blue power supply line, and the second blue contact spring of the second lamp 66. Connected to LED lead. Further, the common conductor of the first wiring duct rail 60 is connected to the common conductor via the first common contact spring, the common wire, and the second common contact spring of the second lamp 66. As described above, in the lighting device 100, the second lamp 66 has a function of electrically connecting the first wiring duct rail 60 and the second wiring duct rail 62.

照明装置１００においても、第１配線ダクトレール６０または第２配線ダクトレール６２の一端を図示しない制御装置に接続し、各導線の電位を制御することにより、第１灯具６４、第２灯具６６、第３灯具６８に搭載された赤色ＬＥＤ、緑色ＬＥＤ、青色ＬＥＤの発光強度を制御することができるので、フルカラー発光を行うことができる。   Also in the lighting device 100, by connecting one end of the first wiring duct rail 60 or the second wiring duct rail 62 to a control device (not shown) and controlling the potential of each conductor, the first lamp 64, the second lamp 66, Since the emission intensity of the red LED, the green LED, and the blue LED mounted on the third lamp 68 can be controlled, full color emission can be performed.

照明装置１００を商業空間の装飾用途に用いるとき、数メートルから数十メートルに渡って配線ダクトレールの敷設が必要な場合がある。そのような場合には、ある所定の長さの配線ダクトレールをいくつか連結することによって所望の長さの配線ダクトレールを得ることができるが、配線ダクトレール間の接続にジョイナーを用いると、ジョイナーの位置する箇所には灯具が配置できない。そのため、配線ダクトレールの繋ぎ目では、連続したＬＥＤの発光がとぎれ、装飾効果が低下してしまう。本実施の形態に係る照明装置１００によれば、配線ダクトレールの繋ぎ目でも発光の連続性がとぎれることがなく、装飾効果を高めることができる。   When the lighting device 100 is used for decoration purposes in commercial spaces, it may be necessary to lay wiring duct rails over several meters to several tens of meters. In such a case, it is possible to obtain a wiring duct rail of a desired length by connecting several wiring duct rails of a predetermined length, but if a joiner is used for connection between the wiring duct rails, Lamps cannot be placed where the joiner is located. Therefore, at the joint of the wiring duct rails, continuous LED light emission is interrupted and the decorative effect is reduced. According to lighting apparatus 100 according to the present embodiment, the continuity of light emission is not interrupted even at the joints of the wiring duct rails, and the decoration effect can be enhanced.

This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to combinations of the respective constituent elements, and such modifications are also within the scope of the present invention.

例えば、上記の実施の形態では、配線ダクトレールの底面部を基部として、底面部に導線を設けたが、側部を基部として側部に溝を形成し、この側部の溝に断面円形状の導線を収容保持してもよい。この場合も、配線ダクトレールにねじれが生じた場合に、導線は溝部内を回転することができるので、溝部から導線が外れることを防止できる。   For example, in the above-described embodiment, the conductor duct is provided on the bottom surface portion with the bottom surface portion of the wiring duct rail as the base portion, but a groove is formed on the side portion with the side portion as the base portion, and a circular cross section is formed on the groove on the side portion The conductive wire may be accommodated and held. Also in this case, when the wiring duct rail is twisted, the conducting wire can rotate in the groove portion, so that the conducting wire can be prevented from coming off from the groove portion.

また、上記の実施の形態では、灯具において同色のＬＥＤを直列に接続したが、並列に接続してもよい。この場合も、フルカラー発光を行うことができるとともに、配線ダクトレールを電気的に接続することができる灯具を実現できる。   Moreover, in said embodiment, although LED of the same color was connected in series in the lamp, you may connect in parallel. Also in this case, it is possible to realize a lamp that can perform full-color light emission and can be electrically connected to the wiring duct rail.
