本発明は主に仏事等で使用する和ろうそく等を模した灯具であり、炎の形や揺らぎ方等を実物の炎の灯りに近づけたものである。The present invention is a lighting fixture that imitates Japanese candles that are mainly used in Buddhist ceremonies, etc., and the shape and flickering of the flame are made to be similar to that of a real flame.
ロウソクは灯具として昔から使用されてきたものであるが、「火」を使っているので、火災等安全には十分注意をしなければならない。しかしながらちょっとした油断から火災につながることもある。
平成２９年度の消防白書によると灯火による火災が全国で４０３件発生している。
この事故を未然に防ぐために、火を使わず安全で、しかも本物の炎の灯りに近いものを発明した。
例えば、本物のロウソクは火をつけると熱により芯の下部のロウが融け、液体となったロウが毛細管現象により芯の上部へ移動し気体となり燃えている。均一でない芯の微妙な細工や僅かな空気の流れがロウソクの灯りである神秘的な揺らぎをつくっている。
静寂の中においても「動」があるものに「生」を感じる。無機なものであれ「動」を加えることが灯具には必要と考え、その灯りをより本物の炎に近づくように「揺らぎ」を追求した。
仏具としての模擬ロウソクには、炎の形を模した電球やＬＥＤを使用したものがある。また複数のＬＥＤを組み合わせて行灯の中でロウソクの灯りを表現しているものがあるがこれは炎の動きを表現できない。
これらの模擬ロウソクは炎の揺らぎはなく、小型電球を点灯しているにすぎない。また近年ＬＥＤを使用したものがあるが明るさが変化するのみでロウソク独特の揺らぎはない。
特許文献１の装飾用灯具は発光体に電球を使用し、下部に鉄錘を付けている。電球と鉄錘の間に導線を兼ねたコイルにより浮遊支持されている。揺らぎの支点となるコイルは発光体から離れている。電球の下部に取り付けた鉄錘を電磁石で引きつける仕組みのため、上下動となり炎の揺らぎには見えない。電磁石を断続励磁する電子回路のスペースが必要となる。また構造上動作音がある。
特許文献２による模造蝋燭は電球から下方に管があり永久磁石を付けている。支点は永久磁石の上にあり電球から離れている。電磁石は永久磁石の下に置かれて、電流を流すことにより揺れを作ろうとしているが、支点からの電球までの距離が長くまた電磁石に対して永久磁石はＮ極・Ｓ極を磁界内においている。パルス電流で磁界を発生させて永久磁石を動かす仕組みとなっているが、パルス発生時の動きが常に同じで単調である。電球が支点から離れた位置で振れる動きとなり炎の揺れとは見えない。 Candles have been used as lighting devices since ancient times, but because they use fire, great care must be taken to ensure safety, including fire. However, even a little carelessness can lead to a fire.
According to the Fire and Disaster Management Agency White Paper for fiscal year 2017, 403 fires were caused by lighting across the country.
To prevent such accidents from happening, they invented something that is safe, doesn't use fire, and yet provides light that is similar to a real flame.
For example, when a real candle is lit, the heat melts the wax at the bottom of the wick, and the liquid wax moves to the top of the wick by capillary action, where it turns into gas and burns. The subtle intricacy of the uneven wick and the slight air currents create the mysterious flickering of candle light.
Even in silence, something with movement gives a feeling of life. We believe that adding movement to lighting fixtures, even if it is inorganic, is necessary, and we pursued a flickering effect to make the light more similar to a real flame.
Some simulated candles for Buddhist altars use light bulbs or LEDs that mimic the shape of a flame. Some combine multiple LEDs to create the light of a candle inside a lantern, but this cannot express the movement of a flame.
These simulated candles do not have a flickering flame, but are merely a small light bulb. Recently, LEDs have been used, but they only change brightness and do not have the characteristic flickering of a candle.
The decorative lighting fixture in Patent Document 1 uses a light bulb as the light source, and has an iron weight attached to the bottom. It is supported floating by a coil that also serves as a conductor between the light bulb and the iron weight. The coil, which serves as the fulcrum for the fluctuation, is separated from the light source. The iron weight attached to the bottom of the light bulb is attracted by an electromagnet, so it moves up and down and does not look like a flickering flame. Space is required for the electronic circuit that intermittently excites the electromagnet. Also, due to its structure, it produces noise when it is operating.
The imitation candle in Patent Document 2 has a tube below the light bulb with a permanent magnet attached. The fulcrum is above the permanent magnet and is away from the light bulb. An electromagnet is placed below the permanent magnet, and an attempt is made to create a swaying motion by passing an electric current through it, but the distance from the fulcrum to the light bulb is long, and the permanent magnet has its north and south poles in a magnetic field relative to the electromagnet. A magnetic field is generated by a pulse current to move the permanent magnet, but the movement when a pulse is generated is always the same and monotonous. The light bulb sways away from the fulcrum, and does not look like a swaying flame.
従来の炎を模した灯具は炎の揺らぎは無く、実物の炎に近いとは言えない。
本発明は実物の炎に近い灯りとなる灯具を実現することを目的とする。 Conventional lamps that mimic flames do not produce a flickering flame and cannot be said to be close to a real flame.
An object of the present invention is to realize a lighting fixture that produces light close to that of a real flame.
上記の課題を解決すべく、反射板を用いて炎形状に形成された炎部と、前記炎部を揺動自在に支持する支持シャフトと、前記炎部から下方に延びる延伸部と、前記延伸部の下部に取り付けられた磁石と、流れる電流の変化に伴って前記磁石の配置領域における磁界を変化させる磁界発生部と、前記炎部に光りを照射し、不規則に点灯間隔と明るさの少なくとも一方が変化する光源を備え、前記光源と前記磁界発生部は直列接続されていることを特徴とする灯具である。 In order to solve the above problems, a lighting fixture is provided that includes a flame portion formed into a flame shape using a reflector, a support shaft that supports the flame portion so that it can swing freely, an extension portion extending downward from the flame portion, a magnet attached to the lower part of the extension portion, a magnetic field generating portion that changes the magnetic field in the area where the magnet is located in response to changes in the flowing current, and a light source that irradiates light onto the flame portion and changes at least one of the lighting interval and brightness irregularly, wherein the light source and the magnetic field generating portion are connected in series.
本発明の灯具は炎形の反射板が光源の炎色の光を反射し、揺らいでいる。
反射板は電流が流れると磁力の反発で振れ、電流が少なくなると磁界の力が弱くなり重力でもとの位置に戻ろうとする。更に慣性により振れた方向とは反対側に振れるのであるが、振り子のように単純な左右の動きではなく不規則な電流変化により規則性のない自然な揺れとなる。
例えば灯具が模擬ロウソクである場合、実物のロウソクとは違い「火」を使用せずロウソク本来の炎色や揺らぎを再現できた。
これを使用することにより火災等の危険は無くなり違和感なく「火」を使わない安全な灯具として使用でき、就寝時の消し忘れの不安もなく長時間の点灯が可能となる。
本発明は安全であり、本物の炎の揺らぎを再現したものであることから、リビングや寝室等で癒しの効果のある灯具として、利用範囲の拡大が期待できる。
図６は本発明をインテリア灯具として利用した一例である。図６（ａ）は本発明を球形ガラス容器の口部に炎部を設けた灯具である。図６（ｂ）は模擬ロウソクとして複数使用したインテリア灯具である。図６（ｃ）は動作中の図６（ａ）のインテリア灯具の写真である。 In the lighting fixture of the present invention, the flame-shaped reflector reflects and flickers the flame-colored light of the light source.
When current flows through the reflector, it swings due to the repulsion of magnetic forces, and when the current decreases, the strength of the magnetic field weakens and gravity tries to return it to its original position. Furthermore, due to inertia, it swings in the opposite direction to the direction it swung in, but it does not move simply back and forth like a pendulum, but due to the irregular changes in current, it swings in a natural, irregular manner.
For example, when the lighting fixture is a simulated candle, unlike a real candle, it is possible to reproduce the original flame color and flickering of a candle without using fire.
By using this, there is no risk of fire and it can be used as a safe lighting fixture that does not use "fire" without any discomfort, and it can be left on for long periods of time without the worry of forgetting to turn it off when going to sleep.
Because this invention is safe and reproduces the flickering of a real flame, it is expected that its range of use will expand as a soothing lighting fixture in living rooms, bedrooms, etc.
Figure 6 shows an example of the present invention being used as an interior lighting fixture. Figure 6(a) shows a lighting fixture in which a flame is provided at the mouth of a spherical glass container. Figure 6(b) shows an interior lighting fixture in which multiple lamps are used as simulated candles. Figure 6(c) is a photograph of the interior lighting fixture of Figure 6(a) in operation.

The circuit has an LED 4 and a solenoid coil 10 connected in series, and Fig. 4(a) is a circuit diagram using a built-in battery 15. Fig. 4(b) is a circuit diagram using an AC adapter 11. Fig. 4(c) is a circuit diagram in which the built-in battery 15 and the AC adapter 11 are used interchangeably.
By connecting the AC adapter 11 to the AC adapter connector 13 , the built-in battery 15 is disconnected and the device is switched to being driven by the AC adapter 11 .
The value of the current limiting resistor 12 in the circuits of Figures 4(a), (b), and (c) depends on the type of the built-in battery 15 and the AC adapter 11, but is intended to prevent the rated current of the LED 4 from being exceeded.
半透明樹脂で形成された、長尺円筒形の筐体６の上部に、動作支持枠７を取り付け、さらに、前記動作支持枠７に支持シャフト１を取り付けている。前記支持シャフト１は反射板３を回転自由に支持している。前記支持シャフト１が前記反射板３を支持する位置は前記反射板３の重心近傍である。前記支持シャフト１には前記反射板３の位置がずれて前記動作支持枠７に当たらずに炎が中央で揺らぐようにする目的で反射板位置調整２を設けている。前記動作支持枠７に、不規則に間隔と明るさが変化するＬＥＤ４を、前記反射板３の炎形状に形成された炎部に光りが集中するように角度をつけて取り付けている。前記動作支持枠７は半透明樹脂で形成されており前記筐体６の上部に半透明シリコンチューブのスペーサー５で固定されている。
前記反射板３の炎部から下方に伸びる延伸部の下部に、磁石８が装着されている。前記磁石８は筐体下部に装着された、ソレノイドコイル１０の磁界内に臨ませている。 An operating support frame 7 is attached to the top of a long cylindrical housing 6 made of translucent resin, and a support shaft 1 is further attached to the operating support frame 7. The support shaft 1 supports a reflector 3 for free rotation. The position where the support shaft 1 supports the reflector 3 is near the center of gravity of the reflector 3. The support shaft 1 is provided with a reflector position adjustment 2 for the purpose of making the flame flicker in the center without the reflector 3 being misaligned and hitting the operating support frame 7. LEDs 4 with irregular intervals and brightness are attached to the operating support frame 7 at an angle so that light is concentrated on the flame part formed in the flame shape of the reflector 3. The operating support frame 7 is made of translucent resin and is fixed to the top of the housing 6 with a spacer 5 made of translucent silicone tube.
A magnet 8 is attached to the lower part of an extension part extending downward from the flame part of the reflector 3. The magnet 8 faces within the magnetic field of a solenoid coil 10 attached to the lower part of the housing.
安全な灯具を作るため、明かりとして不規則に間隔と明るさが変化するように構成されたＬＥＤ４としてｏｐｔｏｓｕｐｐｌｙ ５ｍｍキャンドルＬＥＤ（黄）ＯＳＹ５ＭＫ５Ａ３１Ａを使用した。前記ＬＥＤ４を回路に接続することにより回路を流れる電流が不規則に変化する。In order to create a safe lamp, an optosupply 5mm candle LED (yellow) OSY5MK5A31A was used as the LED 4, which is configured to have irregular intervals and brightness changes as a light. By connecting the LED 4 to a circuit, the current flowing through the circuit changes irregularly.
本物のロウソクの揺らぎを再現するには、作動部位が軽くなければならない。炎にあたる部分に発光体（電球、ＬＥＤ等）を使うと重くなり、また電流供給のための接点等の仕組みにより動作を妨げることになり、揺らぎの再現に支障がある。
上記の理由より可動部を反射板として炎形に形成し、外部より光を投射しロウソクの明かりを模した。 To reproduce the flickering of a real candle, the operating parts must be light. If a light source (light bulb, LED, etc.) is used in contact with the flame, it will be heavy, and the mechanism for supplying current, such as contacts, will interfere with the operation, making it difficult to reproduce the flickering sound.
For the above reasons, the moving part is formed into a flame shape and used as a reflector, and light is projected from outside to imitate candle light.
炎部分の揺らぎはソレノイドコイル１０と磁石８の反発と重力及び慣性により実現している。自然な揺らぎを作るために、前記ソレノイドコイル１０に流れる電流を不規則にした。これにより前記ソレノイドコイル１０に発生する不規則な磁界の変化により炎形の反射板３の延伸部に取り付けている前記磁石８を揺動させている。The flickering of the flame is achieved by the repulsion between the solenoid coil 10 and the magnet 8, as well as gravity and inertia. In order to create a natural flickering, the current flowing through the solenoid coil 10 is made irregular. This causes the irregular magnetic field changes generated in the solenoid coil 10 to cause the magnet 8 attached to the extension of the flame-shaped reflector 3 to flicker.
ソレノイドコイル１０に流す不規則な強弱のある電流は、不規則に間隔と明るさが変化するＬＥＤ４に内蔵されている電流変化機能を利用している。この前記ＬＥＤ４と前記ソレノイドコイル１０を直列接続することにより実現している。
したがって、前記ソレノイドコイル１０に流れる電流値は前記ＬＥＤ４に流れる電流値と同じであり、前記ＬＥＤ４を点灯させるための電流で前記ソレノイドコイル１０に磁界を発生させている。
これにより不規則電流を作る電子回路を無くしたシンプルな回路となり、かつ消費電力を少なくした。 The current with irregular strengths that flows through the solenoid coil 10 utilizes a current change function built into the LED 4, which changes its interval and brightness irregularly. This is realized by connecting the LED 4 and the solenoid coil 10 in series.
Therefore, the value of the current flowing through the solenoid coil 10 is the same as the value of the current flowing through the LED 4, and a magnetic field is generated in the solenoid coil 10 by the current for lighting the LED 4.
This has resulted in a simpler circuit that eliminates the electronic circuits that create irregular currents and also reduces power consumption.
反射板３の揺れを妨げる支持シャフト１と前記反射板３のシャフト穴との摩擦を少なくするため、前記反射板３のシャフト穴は前記支持シャフト１の太さより大きくしている。
そのため、前記反射板３は前記支持シャフト１の方向に動いたり、前記支持シャフト１と直角方向に揺れ動いたり、すりこぎ運動をする。前記反射板３のすりこぎ運動を防ぎ、前記支持シャフト１の方向より前記支持シャフト１と直角方向に大きく揺動させるために、本発明ではコイルボビンの巻き芯部分の断面形状が円ではなく楕円もしくは長方形のボビンを使用することにより前記支持シャフト１と直角方向の揺れが大きくなることを明確に確認した。 In order to reduce friction between the support shaft 1, which prevents the reflector 3 from swinging, and the shaft hole of the reflector 3, the shaft hole of the reflector 3 is made larger than the thickness of the support shaft 1.
Therefore, the reflector 3 performs a rolling motion, moving in the direction of the support shaft 1 and swinging in a direction perpendicular to the support shaft 1. In order to prevent the rolling motion of the reflector 3 and to swing more in the direction perpendicular to the support shaft 1 than in the direction of the support shaft 1, it has been clearly confirmed that the swing in the direction perpendicular to the support shaft 1 becomes larger by using a bobbin in the present invention in which the cross-sectional shape of the winding core part of the coil bobbin is elliptical or rectangular rather than circular.
さらに本発明では自然な炎の揺れを作るために、ＬＥＤ４と直列接続することによる不規則な電流でソレノイドコイル１０を励磁し、発生した磁界内に臨ませた磁石８が電流の不規則な強弱に応じて、電流が強くなると緩やかに反発し、電流が弱くなると重力の働きで鉛直方向に動く磁界の強さを作るため、前記ソレノイドコイル１０の巻き数と、反射板３の質量と、前記反射板３の炎部と延伸部の長さの比と、前記反射板３の炎部と延伸部の質量バランスと、前記磁石８の質量及び前記磁石８の磁力の強度を研究し結果を出した。Furthermore, in this invention, in order to create a natural flickering of the flame, the solenoid coil 10 is excited by an irregular current by connecting it in series with the LED 4, and the magnet 8 facing the generated magnetic field creates a magnetic field strength in which, depending on the irregular strength of the current, it gently repels when the current is strong and moves vertically due to the action of gravity when the current is weak. In order to achieve this, research was conducted on the number of turns of the solenoid coil 10, the mass of the reflector 3, the ratio of the length of the flame part and the extension part of the reflector 3, the mass balance of the flame part and the extension part of the reflector 3, the mass of the magnet 8 and the strength of the magnetic force of the magnet 8, and results were obtained.
反射板３が大きく振れ、前記反射板３の延伸部に取り付けた磁石８が筐体に接触する場合があるので前記磁石８は緩衝材９により保護している。これにより動作音を消している。There is a possibility that the reflector 3 will swing too much and the magnet 8 attached to the extension of the reflector 3 will come into contact with the housing, so the magnet 8 is protected by a cushioning material 9. This reduces the operating noise.
実物のロウソクでは燃焼による明かりがロウソク本体上部をほんのりと照らしている。
この状態を模擬ロウソクとして再現するために動作支持枠７及び筐体６、前記動作支持枠７と前記筐体６の間のスペーサー５はＬＥＤ４の発光色を遮らないような透明もしくは半透明樹脂を使用し、前記ＬＥＤ４の側部や下部からの明かりを使い再現した。 In a real candle, the light from burning gently illuminates the top of the candle body.
In order to reproduce this state as a simulated candle, the motion support frame 7, the housing 6, and the spacer 5 between the motion support frame 7 and the housing 6 are made of transparent or semi-transparent resin that does not block the light emitted by the LED 4, and the state is reproduced using light from the sides and bottom of the LED 4.
このため図５（ａ）で示したように、筐体６に被せ、かつ交換できるロウソク外筒部１６は、ロウソクの質感を持つ半透明乳白色樹脂を使用し、季節の花等を描き、つけ換えることにより内側から図柄の紋様を柔らかく照らし出し風情を楽しむことができる。
また、仏事では前記ロウソク外筒部１６に文字や故人の俗名・法名等を書くこともできるようにした。 For this reason, as shown in FIG. 5(a), the candle outer cylinder 16, which can be replaced and placed over the housing 6, is made of translucent milky white resin with the texture of a candle, and by drawing seasonal flowers or the like on it and replacing it, the pattern of the design is softly illuminated from the inside, allowing you to enjoy the atmosphere.
In addition, during Buddhist ceremonies, it is possible to write characters, the secular name or posthumous name of the deceased, etc. on the outer cylinder 16 of the candle.
反射板３には灯具の炎色を再現するためＬＥＤ４の発光色を妨げない半透明樹脂を使い、前記ＬＥＤ４の光を反射させている。なお炎部の灯りは後方からも視認できる。The reflector 3 is made of a semi-transparent resin that does not interfere with the light emitted by the LED 4 in order to reproduce the flame color of the lamp, and reflects the light of the LED 4. The light of the flame can be seen from behind.
本発明は長時間の連続使用を前提にしているため部品点数を極力減らして消費電力を少なくしている、これにより乾電池等の内蔵電池１５の使用でも長時間の動作を可能としている。Since the present invention is premised on long-term continuous use, the number of parts is reduced as much as possible to reduce power consumption, thereby enabling long-term operation even with the built-in battery 15 such as a dry cell.
図５（ａ）は一例として燭台に瓢箪を使った実施例である。図５（ｂ）の交換出来るロウソク外筒部１６は、筐体６の上に被せて使用するものであり、季節の花等を描いた図である。図５（ｃ）は動作中の模擬ロウソクの写真である。Fig. 5(a) shows an example of an embodiment using a gourd as a candlestick. Fig. 5(b) shows a replaceable candle outer cylinder 16, which is used by covering the housing 6, and is a drawing of seasonal flowers, etc. Fig. 5(c) is a photograph of the simulated candle in operation.
部品点数が少なくパーツの全てが筐体内に収まるため、燭台のデザインは自由度がある。図６（ａ）は筐体６と燭台１４を一体化した実施例である。図６（ｂ）は燭台１４を使用せず灯具本体のみで構成した灯具の一例である。図６（ｃ）は図６（ａ）の動作中の写真である。このように灯具としての利用の範囲が広く、様々なデザインや活用シーンが考えられる。Since the number of parts is small and all parts fit inside the housing, there is a degree of freedom in the design of the candlestick. Fig. 6(a) is an embodiment in which the housing 6 and the candlestick 14 are integrated. Fig. 6(b) is an example of a lamp that does not use the candlestick 14 and is composed only of the lamp body. Fig. 6(c) is a photograph of Fig. 6(a) in operation. As such, the range of uses as a lamp is wide, and various designs and usage scenes are conceivable.
