しかしながら、ネオン管や蛍光灯は文字などを模ろうとしても限界があり、複雑な文字や角度が鋭い場合には模れないことがある。また、ネオン管や蛍光灯は３６０°全方位に対して発光するためどの方向からも視認できる反面、壁などに設けて一方向からのみ見る場合は電力が無駄になるという欠点がある。 However, neon tubes and fluorescent lamps have limitations even if they try to imitate characters, and may not imitate when complex characters and angles are sharp. Further, while the neon tube or a fluorescent lamp that is visible from any direction for emitting light with respect to 360 ° omnidirectional, to view only one direction is provided to a wall there is a disadvantage that power is wasted.

本考案が解決しようとする課題は、形状追従性に富み、主として一方向からの視認性に優れて消費電力を抑制できる装飾照明装置を提供することである。 The problem to be solved by the present invention is to provide a decorative lighting device that is rich in shape followability, is excellent mainly in visibility from one direction, and can suppress power consumption.

本考案は、可撓性及び透光性を有するチューブ内に、それぞれの発光面が同一方向を指向するように複数の発光ダイオード素子を配置することにより、上記課題を解決する。 This invention solves the said subject by arrange | positioning several light emitting diode elements so that each light emission surface may face the same direction in the tube which has flexibility and translucency.

本考案によれば、可撓性及び透光性を有するチューブにより装飾照明装置の外装体を構成し、また発光体が発光ダイオードであるため、文字・図形・記号その他の、模るべき形状が複雑かつ鋭角に屈曲していても容易に模ることができる。また、発光ダイオードは発光面が同一方向に指向されて配置されているので、視認方向以外への余計な光エネルギがなく、無駄な電力の消費を抑制することができる。 According to the present invention, the exterior body of the decorative lighting device is constituted by the flexible and translucent tube, and the light emitter is a light emitting diode, so that there are characters, figures, symbols, and other shapes to be imitated. Even if it is complicated and bent at an acute angle, it can be easily imitated. Further, since the light emitting diodes are arranged with the light emitting surfaces oriented in the same direction, there is no extra light energy in directions other than the viewing direction, and wasteful power consumption can be suppressed.

本考案に係る装飾照明装置１は、家屋内外に設けられ、文字・図形・記号その他の形状を模ったイルミネーションとして機能する照明装置であり、たとえば図１に示すようにアルファベットのＲを模る形状とすることができる。本例の装飾照明装置１は、商用交流電源２に接続される差し込みプラグ１１と、当該差し込みプラグ１１を一端に有しＡＣ／ＤＣアダプタ１２を介してＬＥＤ光源１３へ電力を供給する電力供給線１４と、交流電力を整流して直流電力に変換するＡＣ／ＤＣアダプタ１２と、複数のＬＥＤ光源１３と、変換された直流電力をＬＥＤ光源の定格電圧に調整する複数の抵抗回路１５と、を備える。図２に電気回路図を示す。なお、複数のＬＥＤ光源１３の間の電力供給線１８には、各ＬＥＤ光源１３に印加される電圧を調整するための抵抗回路１５が直列に接続されているが、この抵抗回路１５は必要に応じて省略し、ＡＣ／ＤＣアダプタ１２にてＬＥＤ光源１３の定格電圧を考慮した電圧まで降圧してもよい。 A decorative lighting device 1 according to the present invention is a lighting device that is provided outside a house and functions as an illumination simulating characters, figures, symbols, and other shapes. For example, as shown in FIG. It can be a shape. The decorative lighting device 1 of this example includes a plug 11 connected to a commercial AC power supply 2 and a power supply line that has the plug 11 at one end and supplies power to the LED light source 13 via the AC / DC adapter 12. 14, an AC / DC adapter 12 that rectifies AC power and converts it into DC power, a plurality of LED light sources 13, and a plurality of resistance circuits 15 that adjust the converted DC power to the rated voltage of the LED light source, Prepare. FIG. 2 shows an electric circuit diagram. In addition, although the resistance circuit 15 for adjusting the voltage applied to each LED light source 13 is connected in series to the power supply line 18 between the plurality of LED light sources 13, this resistance circuit 15 is necessary. Accordingly, the AC / DC adapter 12 may step down to a voltage that takes into account the rated voltage of the LED light source 13.

本例のＡＣ／ＤＣアダプタ１２は、変圧回路と整流回路と必要に応じて安定化回路を備え、コンセントから供給される商用交流電力を変圧回路によって降圧させたのち整流回路によって整流し、シリーズレギュレータやスイッチングレギュレータなどの安定化回路を経由することで直流電力を出力する。 The AC / DC adapter 12 of the present example includes a transformer circuit, a rectifier circuit, and a stabilization circuit as necessary. The commercial AC power supplied from the outlet is stepped down by the transformer circuit and then rectified by the rectifier circuit. DC power is output via a stabilization circuit such as a switching regulator.

本例の装飾照明装置１は、発光部分として可撓性、防水性及び透光性を有し、主要断面が矩形断面とされたチューブ１６と、このチューブ１６内に収容された複数のＬＥＤ光源１３と、を備える。チューブ１６は、透明又は半透明の透光性を有する、ポリ塩化ビニルなどの合成樹脂から構成され、その外形断面が長方形や正方形などの矩形とされている。図４の断面図に示すように、ポリ塩化ビニル樹脂により一体的に生成されたチューブ１６は、内部に断面が一様な矩形の空間１６Ｂを有し、この空間１６Ｂに複数のＬＥＤ光源１３が実装された帯状のフレキシブル基板１７が収容されている。 The decorative lighting device 1 of the present example has a flexible, waterproof, and translucent light-emitting portion, a tube 16 whose main cross section is a rectangular cross section, and a plurality of LED light sources accommodated in the tube 16 13. The tube 16 is made of a transparent or translucent light-transmitting synthetic resin such as polyvinyl chloride, and its outer cross section is a rectangle such as a rectangle or a square. As shown in the cross-sectional view of FIG. 4, the tube 16 integrally formed of polyvinyl chloride resin has a rectangular space 16B having a uniform cross section inside, and a plurality of LED light sources 13 are provided in the space 16B. The mounted strip-shaped flexible substrate 17 is accommodated.

また図４に示すように、チューブ１６の下側の隅部には、電力供給線１４の一対の電線に接続された一対の電力供給線１８，１８が、挿通され、その間に溝部１６Ａがチューブ１６の延在方向に一様に形成されている。溝部１６Ａは、チューブ１６の可撓性をより高める効果を奏する。特に両端に電力供給線１８，１８が挿通されると、チューブ１６の可撓性が低下するため、溝部１６Ａを形成することでこれを補うことができる。 As shown in FIG. 4, a pair of power supply lines 18 and 18 connected to a pair of electric wires of the power supply line 14 are inserted into the lower corner of the tube 16, and a groove 16 A is interposed between the pair of power supply lines 18 and 18. It is uniformly formed in 16 extending directions. The groove portion 16 A has an effect of further increasing the flexibility of the tube 16. In particular, when the power supply lines 18 and 18 are inserted at both ends, the flexibility of the tube 16 is lowered, so that this can be compensated by forming the groove portion 16A.

図１に戻り、チューブ１６の基端１６Ｃは、電気コードである電力供給線１４の一対の電線に接続されたうえで封止され、チューブ１６の先端１６Ｄも封止されている。これにより、チューブ１６内は防水状態となり、風雨に曝される屋外においても使用することができる。 Returning to FIG. 1, the proximal end 16 C of the tube 16 is sealed after being connected to a pair of electric wires of the power supply line 14, which is an electrical cord, and the distal end 16 D of the tube 16 is also sealed. Thereby, the inside of the tube 16 is in a waterproof state, and can be used even outdoors exposed to wind and rain.

本例のＬＥＤ光源１３は、可撓性を有するフレキシブル基板１７に所定間隔をおいて実装されている。図３（Ａ），（Ｂ）は、この基板１７を示す平面図及び背面図であり、図３（Ｃ）は図３（Ａ）のIIIC-IIIC線に沿う断面図である。本例のフレキシブル基板１７は、ポリイミドやポリエステルなどから構成され基材となる第１絶縁性フィルム１７Ｃと、当該絶縁性フィルム１７Ｃの表面に形成され銅箔などからなる導電性パターン層１７Ｂと、フレキシブル基板１７の表面を構成する第２絶縁性フィルム１７Ａと、の三層構造とされている。 The LED light source 13 of this example is mounted on a flexible substrate 17 having flexibility at a predetermined interval. 3A and 3B are a plan view and a rear view showing the substrate 17, and FIG. 3C is a cross-sectional view taken along line IIIC-IIIC in FIG. 3A. The flexible substrate 17 of this example includes a first insulating film 17C that is made of polyimide or polyester and serves as a base material, a conductive pattern layer 17B that is formed on the surface of the insulating film 17C and made of copper foil, and the like. A three-layer structure including the second insulating film 17 A constituting the surface of the substrate 17 is employed.

そして、第１絶縁性フィルム１７Ｃはフレキシブル基板１７の全域に延在するが、導電性パターン１７Ｂは、図３（Ｂ）に示すようにＬＥＤ光源を構成するＬＥＤチップ１３と、抵抗回路を構成する抵抗チップ１５とを実装する部位で分断され、この分断された両パターンを跨ぐようにＬＥＤチップ１３や抵抗チップ１５が実装されることにより、図２に示すように複数のＬＥＤ光源１３と抵抗回路１５とが直列に接続されることになる。なお、フレキシブル基板１７の表面を構成する第２絶縁性フィルム１７Ａは、ＬＥＤチップ１３及び抵抗チップ１５の実装部位において切り欠かれている。 The first insulating film 17C extends over the entire area of the flexible substrate 17, but the conductive pattern 17B constitutes a resistance circuit with the LED chip 13 constituting the LED light source as shown in FIG. 3B. When the LED chip 13 and the resistor chip 15 are mounted so as to straddle both divided patterns, the plurality of LED light sources 13 and the resistor circuit are mounted as shown in FIG. 15 are connected in series. Note that the second insulating film 17 A constituting the surface of the flexible substrate 17 is cut away at the mounting portion of the LED chip 13 and the resistor chip 15.

また、図３（Ｂ）に示す導電性パターン１７Ｂの基端及び先端は、チューブ１６の基端１６Ｃから先端１６Ｄまで延在し、最も基端側の導電性パターン１７Ｂに電力供給線１８，１８の一方（たとえばプラス側）が電気的に接続され、最も先端側の導電性パターン１７Ｂに電力供給線１８，１８の他方（たとえばマイナス側）が電気的に接続されている。 3B extends from the proximal end 16C of the tube 16 to the distal end 16D, and the power supply lines 18 and 18 are connected to the conductive pattern 17B on the most proximal side. One (for example, the plus side) is electrically connected, and the other of the power supply lines 18 and 18 (for example, the minus side) is electrically connected to the conductive pattern 17B on the most distal end side.

以上のように、本例の装飾照明装置１によれば、複数のＬＥＤ光源１３がフレキシブル基板１７の一面に沿って実装された状態で可撓性を有する断面矩形のチューブ１６の内部空間１６Ｂに収容されているので、図１に示すように、予めチューブ１６をＲ字状に曲げて成形するか、あるいは直線状に成形したチューブ１６をＲ字状に曲げて固定手段により固定することで、文字Ｒを模ったイルミネーションとして用いることができる。勿論、ＬＥＤ光源１３であることからチューブ１６を屈曲しても発光が抑制されることはなく、しかも本例のＬＥＤ光源１３はフレキシブル基板１７の一面に実装されて一方向にのみ指向性を有するので、こうした用途に適用すると無駄な電力の消費を抑制することができる。 As described above, according to the decorative lighting device 1 of the present example, the plurality of LED light sources 13 are mounted in the internal space 16B of the tube 16 having a rectangular section having flexibility in a state where the LED light sources 13 are mounted along one surface of the flexible substrate 17. Since it is accommodated, as shown in FIG. 1, by bending the tube 16 in an R shape in advance, or by bending the tube 16 formed in a straight shape into an R shape and fixing it by a fixing means, It can be used as an illumination imitating the letter R. Of course, since it is the LED light source 13, light emission is not suppressed even if the tube 16 is bent, and the LED light source 13 of this example is mounted on one surface of the flexible substrate 17 and has directivity only in one direction. Therefore, useless power consumption can be suppressed when applied to such applications.
