以下、本発明に係る実施形態の照明器具について、図面を用いて説明する。
なお、以下の説明においては、照明器具を被取付面である天井面に取り付けて下方を照明する場合について説明する。従って、特に示す場合を除き、上（上方、上側等）は天井面側を意味し、下（下方，下側等）は床面側を意味する。 (First embodiment)
Hereinafter, the lighting fixture of embodiment which concerns on this invention is demonstrated using drawing.
In addition, in the following description, the case where a lighting fixture is attached to the ceiling surface which is a to-be-attached surface, and the downward direction is illuminated is demonstrated. Therefore, unless otherwise indicated, upper (upper, upper, etc.) means the ceiling surface side, and lower (lower, lower, etc.) means the floor surface side.

図１に示すように、本発明に係る実施形態の照明器具１０は、被取付面である天井面１１等に取り付けられて主に下方を照明するのに適する。
図２および図３に示すように、照明器具１０は、天井面１１に取り付けられている引っ掛けシーリング１２に取り付けるための取付金具２１を中央に有する例えば正方形の板状の器具本体２０を有する。 As shown in FIG. 1, the lighting fixture 10 of embodiment which concerns on this invention is suitable for attaching to the ceiling surface 11 grade | etc., Which is a to-be-attached surface, and mainly illuminating below.
As shown in FIG. 2 and FIG. 3, the lighting fixture 10 has, for example, a square plate-like fixture main body 20 having a fitting 21 for attachment to the hook ceiling 12 attached to the ceiling surface 11.

器具本体２０の上側（すなわち、天井面１１側）には、照明装置３０（以下、ＬＥＤユニット３０と呼ぶ）であるアッパーユニット３０Ａ、上枠２３および上パネル２２が設けられている。また、器具本体２０の下側（すなわち、照明方向側）には、ＬＥＤユニット３０であるロアーユニット３０Ｂ、反射部材である反射板２４が設けられており、反射板２４の下方には、受けた光を拡散する透光性のパネル２５が取り付けられる。
パネル２５は、例えば正方形状をしており、対向する端部には、光を透過しないパネルカバー２５１が設けられている。 An upper unit 30A, which is an illumination device 30 (hereinafter referred to as an LED unit 30), an upper frame 23, and an upper panel 22 are provided on the upper side of the instrument body 20 (that is, on the ceiling surface 11 side). Further, a lower unit 30B that is an LED unit 30 and a reflecting plate 24 that is a reflecting member are provided on the lower side of the instrument body 20 (that is, on the illumination direction side). A translucent panel 25 that diffuses light is attached.
The panel 25 has a square shape, for example, and a panel cover 251 that does not transmit light is provided at opposite ends.

次に、アッパーユニット３０Ａおよびロアーユニット３０Ｂに用いられるＬＥＤユニット３０について説明する。
なお、以下においては、特にアッパーユニット３０Ａおよびロアーユニット３０Ｂを区別する場合を除き、ＬＥＤユニット３０として説明する。
図４に示すように、アッパーユニット３０Ａは、器具本体２０の上側において、四方外向きに設けられている。また、ロアーユニット３０Ｂは、器具本体２０の下側において、２カ所に設けられており、内側へ光を照射するようになっている。 Next, the LED unit 30 used for the upper unit 30A and the lower unit 30B will be described.
In the following description, the LED unit 30 will be described unless the upper unit 30A and the lower unit 30B are particularly distinguished.
As shown in FIG. 4, the upper unit 30 </ b> A is provided outward in all directions on the upper side of the instrument body 20. Further, the lower unit 30B is provided at two places on the lower side of the instrument body 20, and radiates light inward.

図３に示すように、上述したＬＥＤユニット３０を用いた照明器具１０では、器具本体２０の下側に設けられているロアーユニット３０Ｂから照明器具１０の内部に向かって発せられた光Ｌ１は、反射板２４で下方に反射してパネル２５に入射して拡散する。これにより、パネル２５全体が光源となって下方を照明する。
一方、器具本体２０の上側に設けられているアッパーユニット３０Ａから照明器具１０の外側へ発せられた光Ｌ２は、天井面１１へ照射される。 As shown in FIG. 3, in the lighting fixture 10 using the LED unit 30 described above, the light L1 emitted toward the inside of the lighting fixture 10 from the lower unit 30B provided on the lower side of the fixture main body 20 is The light is reflected downward by the reflecting plate 24 and is incident on the panel 25 and diffuses. Thereby, the whole panel 25 becomes a light source and illuminates the lower part.
On the other hand, light L <b> 2 emitted from the upper unit 30 </ b> A provided on the upper side of the fixture body 20 to the outside of the lighting fixture 10 is irradiated to the ceiling surface 11.

図５および図６に示すように、ＬＥＤユニット３０は、例えば細長い矩形状の基板３１を有しており、その実装面３１１には、種類が異なる複数の第１のＬＥＤ光源３２Ａと複数の第２のＬＥＤ光源３２Ｂが実装されている。なお、２種類のＬＥＤ光源３２Ａ、３２Ｂを総称する際には、「ＬＥＤ光源３２」と表示する。
また、実装面３１１において、長手方向の基板両端から見て端部のＬＥＤ光源３２より内側の位置に、電気配線が接続されて電力の供給を受ける電気接続部としてのコネクタ３３が取り付けられる。
複数の第１のＬＥＤ光源３２Ａは、第１の回路３４Ａにより直列に接続されており、複数の第２のＬＥＤ光源３２Ｂは、第１のＬＥＤ光源３２Ａとは別系統で、第２の回路３４Ｂにより直列に接続されている。 As shown in FIGS. 5 and 6, the LED unit 30 includes, for example, an elongated rectangular substrate 31, and the mounting surface 311 includes a plurality of first LED light sources 32 </ b> A of different types and a plurality of first LED light sources 32 </ b> A. Two LED light sources 32B are mounted. In addition, when naming two types of LED light sources 32A and 32B generically, "LED light source 32" is displayed.
On the mounting surface 311, a connector 33 is attached as an electrical connection portion to which electric wiring is connected and supplied with electric power at a position inside the LED light source 32 at the end portion as viewed from both ends of the substrate in the longitudinal direction.
The plurality of first LED light sources 32A are connected in series by the first circuit 34A, and the plurality of second LED light sources 32B are separate from the first LED light source 32A, and the second circuit 34B. Are connected in series.

従って、第１のＬＥＤ光源３２Ａと第２のＬＥＤ光源３２Ｂは、個別に制御可能となっている。
また、第１の回路３４Ａと第２の回路３４Ｂとは別個であり、例えば、クランク状に配線することができる。このとき、第１の回路３４Ａおよび第２の回路３４Ｂのクランク形状が、平行となるように配線する。 Therefore, the first LED light source 32A and the second LED light source 32B can be individually controlled.
Further, the first circuit 34A and the second circuit 34B are separate and can be wired in a crank shape, for example. At this time, wiring is performed so that the crank shapes of the first circuit 34A and the second circuit 34B are parallel to each other.

第１のＬＥＤ光源３２Ａと第２のＬＥＤ光源３２Ｂは、一部を除き各々偶数個（ここでは、例えば２個）をひとかたまりとして、交互に配置されている。そして、端部においては、その隣（内側）に配設されたＬＥＤ光源３２とは異なる種類のＬＥＤ光源３２が配設される。
例えば、図５中、下端部では、端部に第１のＬＥＤ光源３２Ａが配設されているので、その隣には、異なる種類の第２のＬＥＤ光源３２Ｂが配設される。 The first LED light source 32A and the second LED light source 32B are alternately arranged with a group of even numbers (here, for example, two) except for a part. And in the edge part, the LED light source 32 of a kind different from the LED light source 32 arrange | positioned next (inner side) is arrange | positioned.
For example, in FIG. 5, since the first LED light source 32A is arranged at the lower end portion, a different type of second LED light source 32B is arranged next to the lower end portion.

ここで、図５中のＡ部および図６中Ａ部を拡大した図７に示すように、ＬＥＤ光源３２は、シリコン樹脂からなるレンズ３２１を有する。このレンズ３２１は、製造時のばらつきによりある一方向へずれて取り付けられている場合がある。例えば、図７に示すように、レンズ３２１がカソードマーク３２２Ａ側（図７において右側）へずれている場合、ＬＥＤ光源３２の配光はカソード３２２側へずれる。
このため、図７に示すように、ＬＥＤユニット３０では、各々のＬＥＤ光源３２を同一線ＳＴ上に配置し、かつ同一線ＳＴに対して隣り合う少なくとも一対のＬＥＤ光源３２のアノード３２３の位置とカソード３２２の位置とが、左右（図７において左右）に交互に入れ替わる向きに配置して接続する。これにより、各々のＬＥＤ光源３２の配光ずれを打ち消し合う。 Here, as shown in FIG. 7 in which the A portion in FIG. 5 and the A portion in FIG. 6 are enlarged, the LED light source 32 has a lens 321 made of silicon resin. The lens 321 may be attached with being shifted in one direction due to variations in manufacturing. For example, as shown in FIG. 7, when the lens 321 is shifted to the cathode mark 322A side (right side in FIG. 7), the light distribution of the LED light source 32 is shifted to the cathode 322 side.
Therefore, as shown in FIG. 7, in the LED unit 30, each LED light source 32 is arranged on the same line ST and the position of the anode 323 of at least a pair of LED light sources 32 adjacent to the same line ST. The positions of the cathodes 322 are arranged and connected in such a direction that they are alternately switched left and right (left and right in FIG. 7). Thereby, the light distribution deviation of each LED light source 32 is canceled.

以上、説明した本発明に係る第１実施形態の照明装置３０によれば、基板３１に実装される複数のＬＥＤ光源３２のうち少なくとも一対の隣り合うＬＥＤ光源３２の配置を、各々のＬＥＤ光源３２のアノード３２３の位置とカソード３２２の位置とが交互に入れ替わる向きに配置した。
このため、各々のＬＥＤ光源３２の配光ずれを打ち消し合うことができ、ＬＥＤユニット３０の配光が偏ることを防ぐことができる。 As mentioned above, according to the illuminating device 30 of 1st Embodiment which concerns on this invention demonstrated, arrangement | positioning of at least a pair of adjacent LED light source 32 among the several LED light sources 32 mounted in the board | substrate 31 is made into each LED light source 32. The position of the anode 323 and the position of the cathode 322 are alternately arranged.
For this reason, the light distribution deviation of each LED light source 32 can be canceled and the light distribution of the LED unit 30 can be prevented from being biased.

複数のＬＥＤ光源３２を同一線ＳＴ上に配置して、この同一線ＳＴに沿ってＬＥＤ光源３２のアノード３２３の位置とカソード３２２の位置とが同一線ＳＴに対して左右交互に入れ替わる向きに配置した。このため、各々のＬＥＤ光源３２の配光ずれを打ち消し合うことができ、ＬＥＤユニット３０の配光が偏ることを防ぐことができる。   A plurality of LED light sources 32 are arranged on the same line ST, and are arranged in such a direction that the positions of the anode 323 and the cathode 322 of the LED light source 32 are alternately switched to the left and right with respect to the same line ST along the same line ST. did. For this reason, the light distribution deviation of each LED light source 32 can be canceled and the light distribution of the LED unit 30 can be prevented from being biased.

コネクタ３３の配置を、基板３１の端部から見てＬＥＤ光源３２より内側にしたため、ＬＥＤユニット３０を連結した場合、繋ぎ目の輝度低減を防ぐことができ、輝度ムラが更に軽減され、配光の偏りを防ぐことができる。   Since the connector 33 is arranged on the inner side of the LED light source 32 when viewed from the end of the substrate 31, when the LED unit 30 is connected, the brightness of the joint can be prevented from being reduced, and the brightness unevenness can be further reduced, thereby distributing the light. Can be prevented.

以上、説明した本発明に係る第１実施形態の照明器具１０によれば、前述したＬＥＤユニット３０を用いた。すなわち、基板３１に実装される複数のＬＥＤ光源３２のうち少なくとも一対の隣り合うＬＥＤ光源３２の配置を、各々のＬＥＤ光源３２のアノード３２３の位置とカソード３２２の位置とが交互に入れ替わる向きに配置した。このため、各々のＬＥＤ光源３２の配光ずれを打ち消し合うことができ、ＬＥＤユニット３０の配光が偏ることを防ぐことができる。   As mentioned above, according to the lighting fixture 10 of 1st Embodiment which concerns on this invention demonstrated, the LED unit 30 mentioned above was used. That is, at least a pair of adjacent LED light sources 32 among the plurality of LED light sources 32 mounted on the substrate 31 are arranged in directions in which the positions of the anodes 323 and the cathodes 322 of the LED light sources 32 are alternately switched. did. For this reason, the light distribution deviation of each LED light source 32 can be canceled and the light distribution of the LED unit 30 can be prevented from being biased.

また、偶数の第１のＬＥＤ光源３２Ａと偶数の前記第２のＬＥＤ光源３２Ｂとを交互に配置したので、ＬＥＤユニット３０におけるパターン配線を短くして接続できる。
さらに、チップジャンパー抵抗等の部品も削減できるので、コストアップを回避できるとともに、ＬＥＤユニット３０として基板３１の表裏両面をパターン印刷に用いる必要がないので、ＬＥＤユニット３０の実装面３１１と反対側の面を放熱に利用できる。 Moreover, since the even numbered first LED light sources 32A and the even numbered second LED light sources 32B are alternately arranged, the pattern wiring in the LED unit 30 can be shortened and connected.
Further, since components such as a chip jumper resistor can be reduced, it is possible to avoid an increase in cost, and it is not necessary to use both the front and back surfaces of the substrate 31 for pattern printing as the LED unit 30, so that the LED unit 30 is opposite to the mounting surface 311. The surface can be used for heat dissipation.

なお、本発明のＬＥＤユニット３０は、種類が異なる複数の第１のＬＥＤ光源３２Ａと複数の第２のＬＥＤ光源３２Ｂが実装されている場合に限らず、図８に示すように、単一の複数の第１のＬＥＤ光源３２Ａだけで構成されている場合でも適用可能である。
さらに、図９に示すように、コネクタ３３を基板３１の長手方向の両端から見てＬＥＤ光源３２より内側の位置に配置した。このため、ロアーユニット３０Ｂを器具本体２０の下側において、２カ所に連結して設けた場合、繋ぎ目の輝度低減を防ぐことができ、輝度ムラが更に軽減され、配光の偏りを防ぐ効果がある。 The LED unit 30 of the present invention is not limited to the case where a plurality of first LED light sources 32A and a plurality of second LED light sources 32B of different types are mounted, but as shown in FIG. The present invention can also be applied to a case where only a plurality of first LED light sources 32A are configured.
Further, as shown in FIG. 9, the connector 33 is disposed at a position inside the LED light source 32 when viewed from both ends in the longitudinal direction of the substrate 31. For this reason, when the lower unit 30B is provided at two locations on the lower side of the instrument main body 20, it is possible to prevent the brightness of the joint from being reduced, the brightness unevenness is further reduced, and the effect of preventing the uneven distribution of light. There is.

図１０に示すように、ＬＥＤユニット３５は略円形状であり、実装面３１１には、種類が異なる複数の第１のＬＥＤ光源３２Ａと複数の第２のＬＥＤ光源３２Ｂが実装されている。なお、２種類のＬＥＤ光源３２Ａ、３２Ｂを総称する際には、「ＬＥＤ光源３２」と表示する。 (Second Embodiment)

また、実装面３１１には、電気配線が接続されて電力の供給を受ける一対のコネクタ３３が取り付けられる。
複数の第１のＬＥＤ光源３２Ａは、第１の回路３４Ａ（図１１参照）により直列に接続されており、複数の第２のＬＥＤ光源３２Ｂは、第１のＬＥＤ光源３２Ａとは別系統で、第２の回路３４Ｂ（図１１参照）により直列に接続されている。
従って、第１のＬＥＤ光源３２Ａと第２のＬＥＤ光源３２Ｂは、個別に制御可能となっている。 In addition, a pair of connectors 33 to which electric wiring is connected and supplied with electric power are attached to the mounting surface 311.

Therefore, the first LED light source 32A and the second LED light source 32B can be individually controlled.

第１のＬＥＤ光源３２Ａと第２のＬＥＤ光源３２Ｂは、一部を除き各々偶数個（ここでは、例えば２個）をひとかたまりとして、交互に配置されている。
図１０中におけるＢ部を拡大した図１１に示すように、ＬＥＤ光源３２がシリコン樹脂からなるレンズ３２１を備えており、レンズ３２１が製造時のばらつきによりある一方向へずれて取り付けられている場合がある。
例えば、図１１に示すように、レンズ３２１がカソードマーク３２２Ａ側へずれていた場合、ＬＥＤ光源３２の配光はカソード３２２側へずれる。 The first LED light source 32A and the second LED light source 32B are alternately arranged with a group of even numbers (here, for example, two) except for a part.
As shown in FIG. 11 in which the portion B in FIG. 10 is enlarged, the LED light source 32 includes a lens 321 made of silicon resin, and the lens 321 is attached so as to be shifted in one direction due to variations in manufacturing. There is.
For example, as shown in FIG. 11, when the lens 321 is shifted to the cathode mark 322A side, the light distribution of the LED light source 32 is shifted to the cathode 322 side.

そこで、種類が異なる第１のＬＥＤ光源３２Ａと第２のＬＥＤ光源３２Ｂとを有するＬＥＤユニット３５において、複数の第１のＬＥＤ光源３２Ａを直列に接続するとともに複数の第２のＬＥＤ光源３２Ｂを第１のＬＥＤ光源３２Ａとは別系統で直列に接続する。
そして、各々のＬＥＤ光源３２を同一円Ｒ１上に配置し、かつ同一円Ｒ１に対して隣り合う少なくとも一対のＬＥＤ光源３２のアノード３２３の位置とカソード３２２の位置とが、左右交互に入れ替わる向きに配置して接続する。これにより、各々のＬＥＤ光源３２の配光ずれを打ち消し合う。
なお、ＬＥＤユニット３５は、種類が異なる複数の第１のＬＥＤ光源３２Ａと複数の第２のＬＥＤ光源３２Ｂが実装されている場合に限らず、図１２に示すように、単一の複数の第１のＬＥＤ光源３２Ａだけで構成されている場合にも適用可能である。 Therefore, in the LED unit 35 having the first LED light source 32A and the second LED light source 32B of different types, the plurality of first LED light sources 32A are connected in series and the plurality of second LED light sources 32B are connected to the second LED light source 32B. The LED light source 32A is connected in series with a separate system.
Then, the LED light sources 32 are arranged on the same circle R1, and the positions of the anodes 323 and the cathodes 322 of at least a pair of LED light sources 32 adjacent to the same circle R1 are alternately switched in the left and right directions. Place and connect. Thereby, the light distribution deviation of each LED light source 32 is canceled.
Note that the LED unit 35 is not limited to a case where a plurality of first LED light sources 32A and a plurality of second LED light sources 32B of different types are mounted, but as shown in FIG. The present invention can also be applied to a case where only one LED light source 32A is configured.

以上、説明した本発明に係る第２実施形態の照明装置３５および照明器具１０によれば、複数のＬＥＤ光源３２を同一円Ｒ１上に配置して、この同一円Ｒ１に沿ってＬＥＤ光源３２のアノード３２３の位置とカソード３２２の位置とが同一円Ｒ１に対して左右交互に入れ替わる向きに配置した。
このため、各々のＬＥＤ光源３２の配光ずれを打ち消し合うことができ、照明装置３５の配光が偏ることを防ぐことができる。 As mentioned above, according to the illuminating device 35 and the lighting fixture 10 of 2nd Embodiment which concern on this invention demonstrated, the some LED light source 32 is arrange | positioned on the same circle R1, and the LED light source 32 of this LED light source 32 is along this same circle R1. The position of the anode 323 and the position of the cathode 322 are arranged so as to be alternately switched to the left and right with respect to the same circle R1.
For this reason, the light distribution shift of each LED light source 32 can be canceled and the light distribution of the illuminating device 35 can be prevented from being biased.

なお、本発明の照明装置および照明器具は、前述した各実施形態に限定されるものでなく、適宜な変形，改良等が可能である。   In addition, the illuminating device and the luminaire of the present invention are not limited to the above-described embodiments, and appropriate modifications and improvements can be made.
