Description

この発明は、ＬＥＤ複数列式ＬＥＤテープ、詳しくは光源として複数の発光ダイオード（ＬＥＤ）が、複数列で配されたＬＥＤ複数列式ＬＥＤテープに関する。   The present invention relates to an LED multi-row LED tape, and more particularly to an LED multi-row LED tape in which a plurality of light emitting diodes (LEDs) are arranged in a plurality of rows as a light source.

自動車の車体装飾として、複数のＬＥＤが長さ方向に所定ピッチで配置された帯状のフレキシブル基板を、透明な軟質合成樹脂によって被覆したＬＥＤテープが知られている。また近年では、各列のものを異色発光させてＬＥＤテープの装飾性を高めるため、フレキシブル基板に、互いの起点とピッチを一致させてＬＥＤを２列配置したもの（ＬＥＤ複数列式ＬＥＤテープ）も市販されている（例えば、非特許文献１など）。   As an automobile body decoration, an LED tape is known in which a strip-shaped flexible substrate in which a plurality of LEDs are arranged at a predetermined pitch in the length direction is covered with a transparent soft synthetic resin. In recent years, two rows of LEDs are arranged on a flexible substrate so that their origins and pitches coincide with each other in order to enhance the decoration of the LED tape by emitting different colors in each row (LED multi-row type LED tape). Is also commercially available (for example, Non-Patent Document 1).

［平成２９年１０月７日検索］、インターネット＜URL：https://item.rakuten.co.jp/share-style/li12001/?scid=me_ich_conf_order_03&_mpt=101&_mpe=271336-20171108-00202817[Search October 7, 2017], Internet <URL: https://item.rakuten.co.jp/share-style/li12001/?scid=me_ich_conf_order_03&_mpt=101&_mpe=271336-20171108-00202817

しかしながら、特許文献１のＬＥＤが２列配置式のＬＥＤテープでは、このように各列のＬＥＤが、フレキシブル基板の長さ方向の位置が一致するように、一定ピッチでフレキシブル基板上に配列されていた。そのため、各列のＬＥＤを同時発光させたとき、互いの光が干渉し合って各色の鮮明さが低下したり、２色の中間色(例えば、赤色と青色に発光した際の紫色)に見えるおそれがあった。
特に、これらのＬＥＤが、各発光面をフレキシブル基板の幅方向の一方側に揃えた側面発光式のものの場合には、別の問題も発生していた。すなわち、ＬＥＤの発光方向の列を前列、その背後を後列とした場合、後列の各ＬＥＤの直前に存在する前列の各ＬＥＤが、この後列の各ＬＥＤの遮光物体となる。その結果、後列の各ＬＥＤの輝度が低下していた。 However, in the LED tape in which the LEDs of Patent Document 1 are arranged in two rows, the LEDs in each row are arranged on the flexible substrate at a constant pitch so that the positions in the length direction of the flexible substrate coincide with each other. It was. For this reason, when the LEDs in each row are caused to emit light at the same time, the light may interfere with each other, reducing the sharpness of each color, or appearing as an intermediate color between two colors (for example, purple when emitting red and blue) was there.
In particular, when these LEDs are of the side emission type in which the respective light emitting surfaces are aligned with one side in the width direction of the flexible substrate, another problem has occurred. That is, when the LED light emission direction column is the front column and the rear side is the rear column, each LED in the front column immediately before each LED in the rear column is a light shielding object for each LED in the rear column. As a result, the brightness of each LED in the rear row was lowered.

そこで、発明者は鋭意研究の結果、フレキシブル基板に、各列のＬＥＤを互いに千鳥足状となるように配置すれば、各列のＬＥＤを同時発光させた際でも互いの光が干渉しにくく、各色の鮮明度が高まることを知見した。
また、仮に各列のＬＥＤが側面発光式のもの場合には、このように各列のＬＥＤを互いに千鳥足状に配置することで、前列の各ＬＥＤが遮光物体となって後列の各ＬＥＤの輝度が低下する現象もなくなることを知見し、この発明を完成させた。 Therefore, as a result of intensive research, the inventor has arranged the LEDs in each row in a staggered pattern on a flexible substrate, so that even when the LEDs in each row are made to emit light at the same time, the mutual light is less likely to interfere with each other. I found out that the clarity of
Further, if the LEDs in each row are of the side-emitting type, the LEDs in each row are arranged in a staggered manner in this manner, so that the LEDs in the front row become a light shielding object and the luminance of each LED in the rear row As a result, the inventors have found that the phenomenon of decreasing is eliminated, and completed the present invention.

すなわち、この発明は、各列のＬＥＤを同時発光させても互いの光が干渉しにくく、各列のＬＥＤの発光色の鮮明さを高めることができるＬＥＤ複数列式ＬＥＤテープを提供することを目的としている。
また、この発明は、各列のＬＥＤが側面発光式のものの場合に、従来の課題であった前列のＬＥＤが遮光物体となって、後列の各ＬＥＤの輝度を低下させるおそれが解消されるＬＥＤ複数列式ＬＥＤテープを提供することを目的としている。 That is, the present invention provides an LED multi-row type LED tape that can prevent the mutual light from interfering with each other even if the LEDs in each row are simultaneously emitted, and can enhance the clearness of the emission color of the LEDs in each row. It is aimed.
In addition, in the present invention, when each row of LEDs is a side-emitting type, the LED in the front row, which has been a conventional problem, becomes a light-shielding object, and the risk of lowering the brightness of each LED in the rear row is eliminated. The object is to provide a multi-row LED tape.

The LED multi-row LED tape 10 includes a plurality of LEDs 11 and 12 arranged in two rows at predetermined intervals in the length direction. The arranged strip-shaped flexible substrate 13 is housed in a strip-shaped flexible case 14 made of translucent white silicone (soft synthetic resin).

以下、これらの構成体を具体的に説明する。
各ＬＥＤ１１，１２は、ＳＭＤ（表面実装）型のものであって、各発光面１１ａ，１２ａが、フレキシブル基板１３の幅方向の一方側に揃えられた側面発光式のものである。
フレキシブル基板１３は、柔軟性を有したポリイミドからなる幅８ｍｍの細長い薄板（ＦＰＣ）である。フレキシブル基板１３の表面には、それぞれ銅製の第１のプリント回路（配線、電極）１４と、第２のプリント回路１６とが、フレキシブル基板１３の幅方向へ平行に離間した状態でそれぞれ形成されている。なお、フレキシブル基板１３の幅方向において、第１のプリント回路１４のが前方配置され、第２のプリント回路１５が後方配置されている。 Hereinafter, these components will be specifically described.
Each LED 11, 12 is of the SMD (surface mount) type, and each light emitting surface 11 a, 12 a is a side light emitting type in which the light emitting surfaces 11 a, 12 a are aligned on one side in the width direction of the flexible substrate 13.
The flexible substrate 13 is an 8 mm wide thin thin plate (FPC) made of flexible polyimide. A first printed circuit (wiring, electrode) 14 made of copper and a second printed circuit 16 are respectively formed on the surface of the flexible substrate 13 in a state of being separated in parallel in the width direction of the flexible substrate 13. Yes. In the width direction of the flexible substrate 13, the first printed circuit 14 is disposed in the front, and the second printed circuit 15 is disposed in the rear.

各プリント回路１４，１５は、フレキシブル基板１３の長さ方向の一端から他端まで直線状に延びた平行な２本の主配線（＋Ｖ配線とＧＮＤ配線）１７と、これらの主配線１７に一定ピッチで電気的に並列接続された複数の副配線１８ととからなる。
各プリント回路１４，１５の主配線１７の一端は、対応するリード線２０を介して、ＬＥＤ複数列式ＬＥＤテープ１０用のコントローラ１９に電気的に接続されている。 Each printed circuit 14, 15 has two parallel main wirings (+ V wiring and GND wiring) 17 extending linearly from one end to the other end in the length direction of the flexible substrate 13, and fixed to these main wirings 17. And a plurality of sub-wirings 18 electrically connected in parallel at a pitch.
One end of the main wiring 17 of each printed circuit 14, 15 is electrically connected to a controller 19 for the LED multi-row LED tape 10 via a corresponding lead wire 20.

前方配置された第１のプリント回路１５の各副配線１８には、白色(青色、赤色でもよい)に発光するブレーキライト用の３つのＬＥＤ１１と１つの電流制限抵抗１９とが、それぞれ電気的に直列に接続されている。一方、後方配置された第２のプリント回路１６の各副配線１８には、ウインカーライト用のアンバー色に発光する３つのＬＥＤ１２と１つの電流制限抵抗１９とが、それぞれ電気的に直列に接続されている。
このとき、第１のプリント回路１５の各ＬＥＤ１１は、フレキシブル基板１３の全長にわたって所定ピッチで配置されている。一方、第２のプリント回路１６の各ＬＥＤ１２は、第１のプリント回路１５のＬＥＤ１１群を構成するＬＥＤ１１とＬＥＤ１１との間に、ちょうど千鳥足状に配置されている（図１〜図３）。 Each sub-wiring 18 of the first printed circuit 15 disposed in front has three LEDs 11 for brake lights that emit white light (may be blue or red) and one current limiting resistor 19 electrically. Connected in series. On the other hand, each of the sub-wirings 18 of the second printed circuit 16 disposed rearward is electrically connected in series with three LEDs 12 and a current limiting resistor 19 that emit amber light for blinker lights. ing.
At this time, the LEDs 11 of the first printed circuit 15 are arranged at a predetermined pitch over the entire length of the flexible substrate 13. On the other hand, each LED 12 of the second printed circuit 16 is arranged in a staggered pattern between the LEDs 11 constituting the LED 11 group of the first printed circuit 15 (FIGS. 1 to 3).

また、各副配線１８の電流制限抵抗１９は、図２中の左から１番目のＬＥＤ１１（１２）と、２番目のＬＥＤ１１（１２）との間にそれぞれ配されている。そのため、このＬＥＤ複数列式ＬＥＤテープ１０は、フレキシブル基板１３の表面上に表示された破線１３ａに沿って切断することによって、その使用長さを調整することができる。
帯状可撓ケース１４は、長さ６０ｃｍ、幅１５ｍｍ、厚さ３ｍｍの半透明な白色のシリコーンからなる平坦な細長いチューブである。帯状可撓ケース１４の内部空間にフレキシブル基板１３が挿入される。帯状可撓ケース１４の裏面には、図示しない両面テープが貼着されている。 Further, the current limiting resistor 19 of each sub-wiring 18 is arranged between the first LED 11 (12) and the second LED 11 (12) from the left in FIG. For this reason, the LED multi-row LED tape 10 can be adjusted in use length by cutting along the broken line 13 a displayed on the surface of the flexible substrate 13.
The strip-shaped flexible case 14 is a flat, elongated tube made of translucent white silicone having a length of 60 cm, a width of 15 mm, and a thickness of 3 mm. The flexible substrate 13 is inserted into the internal space of the strip-shaped flexible case 14. A double-sided tape (not shown) is attached to the back surface of the belt-like flexible case 14.

次に、図１〜図３を参照して、この発明の実施例１に係るＬＥＤ複数列式ＬＥＤテープ１０の使用方法を説明する。
まず、帯状可撓ケース１４の両面テープを剥がして、帯状可撓ケース１４を自動車のリアライトボックスの所定位置に貼着する。
その後、コントローラ１９の電源コード１８ａを、最終的にバッテリの各電極に電気的に接続するとともに、コントローラ１９の入力側のコード１８ｂを車体に搭載されたブレーキランプの点灯回路と、ウインカーライトの点灯回路とに、それぞれ電気的に接続する。これにより、ブレーキランプの点灯時には、第１のプリント回路１５に電気的に接続されたブレーキライト用の各ＬＥＤ１１が、それぞれ白色に点灯する（図３（ａ））。一方、ウインカーライトの点灯時には、第２のプリント回路１６に電気的に接続されたウインカーライト用の各ＬＥＤ１２が、それぞれアンバー色に点灯する（図３（ｂ））。 Next, with reference to FIGS. 1-3, the usage method of the LED multi-row type LED tape 10 which concerns on Example 1 of this invention is demonstrated.
First, the double-sided tape of the strip-shaped flexible case 14 is peeled off, and the strip-shaped flexible case 14 is attached to a predetermined position of the rear light box of the automobile.
Thereafter, the power cord 18a of the controller 19 is finally electrically connected to each electrode of the battery, the cord 18b on the input side of the controller 19 is turned on, a brake lamp lighting circuit mounted on the vehicle body, and a blinker light lighting Each is electrically connected to the circuit. Thus, when the brake lamp is turned on, each LED 11 for brake light that is electrically connected to the first printed circuit 15 is lit white (FIG. 3A). On the other hand, when the turn signal light is turned on, each of the turn signal light LEDs 12 electrically connected to the second printed circuit 16 is turned on in amber (FIG. 3B).

また、図３（ｃ）に示すように、ブレーキライト用の白色の各ＬＥＤ１１と、ウインカーライト用のアンバー色の各ＬＥＤ１２とを同時に点灯した場合には、従来は白色の各ＬＥＤ１１とアンバー色の各ＬＥＤ１２との光が互いに干渉し合って各色の鮮明さが低下したり、全体として２色の中間色に見えるおそれがあった。
これに対して、ＬＥＤ複数列式ＬＥＤテープ１０にあっては、フレキシブル基板１３の表面に実装された第１のプリント回路１５側の各ＬＥＤ１１と、第２のプリント回路１６側の各ＬＥＤ１２とが互いに千鳥足状となるように配置されているため、各列のＬＥＤ１１，１２を同時発光させた際にも、互いの光が干渉しにくくなり、各色の鮮明度を高めることができる。
また、各列のすべてのＬＥＤ１１，１２として、それぞれの発光面１１ａ、１１ｂが、フレキシブル基板１３との接続面と直交する一側面となった側面発光式のものを採用し、これに加えて隣接する各列のＬＥＤ１１，１２を互いに千鳥足状に配したため、従来の課題であった前列の各ＬＥＤ１１が遮光物体となって、後列の各ＬＥＤ１２の輝度を低下させるおそれもない。 In addition, as shown in FIG. 3C, when the white LEDs 11 for brake lights and the amber LEDs 12 for turn signal lights are turned on simultaneously, conventionally, the white LEDs 11 and the amber colors There is a possibility that the light from each LED 12 interferes with each other and the sharpness of each color is lowered, or the whole color looks like two intermediate colors.
On the other hand, in the LED multi-row type LED tape 10, each LED 11 on the first printed circuit 15 side mounted on the surface of the flexible substrate 13 and each LED 12 on the second printed circuit 16 side are provided. Since they are arranged so as to be staggered from each other, even when the LEDs 11 and 12 in each row are caused to emit light at the same time, the mutual light is less likely to interfere with each other, and the clarity of each color can be increased.
Further, as all the LEDs 11 and 12 in each row, side light emitting type in which each light emitting surface 11a and 11b is one side surface orthogonal to the connection surface with the flexible substrate 13 is adopted, and in addition to this, adjacent ones are adopted. Since the LEDs 11 and 12 in each row are arranged in a staggered pattern, the LEDs 11 in the front row, which has been a conventional problem, become a light-shielding object, and there is no possibility of lowering the luminance of the LEDs 12 in the rear row.

この発明は、複数の発光ダイオード（ＬＥＤ）を光源とするＬＥＤ複数列式ＬＥＤテープの技術として有用である。   The present invention is useful as a technique for an LED multi-row LED tape using a plurality of light emitting diodes (LEDs) as a light source.
