Description

本発明は、照明灯に関し、より詳しくは、既に設置された蛍光灯ソケットに取り付けられた安定器の電源をＬＥＤに適合する直流電源に変換してＬＥＤに供給するように構成することで、既に設置された蛍光灯用ソケットから安定器を分離したり、別途のソケットを設置することなく使用可能な安定器を有する蛍光灯用のＬＥＤ照明灯に関する。   The present invention relates to an illuminating lamp, and more specifically, by converting a power source of a ballast attached to an already installed fluorescent lamp socket into a DC power source suitable for the LED and supplying the LED to the LED, The present invention relates to an LED illuminating lamp for a fluorescent lamp having a ballast that can be used without separating a ballast from an installed fluorescent lamp socket or installing a separate socket.

特に、ＬＥＤの設置される基板をアルミニウムからなるＰＣＢ（ｐｒｉｎｔｅｄ ｃｉｒｃｕｉｔ ｂｏａｒｄ）にて構成し、放熱板を設置して放熱効果を高めるだけでなく、このような基板を多数に分離して製作し、これを組立てて構成することにより製作が容易な安定器を有する蛍光灯用のＬＥＤ照明灯に関する。   In particular, the board on which the LEDs are installed is made of PCB (printed circuit board) made of aluminum, and not only the heat dissipation plate is installed to enhance the heat dissipation effect, but also a large number of such boards are manufactured separately. The present invention relates to an LED illuminating lamp for a fluorescent lamp having a ballast that can be easily manufactured by assembling and configuring the same.

また、ＬＥＤの代わりにツェナーダイオード等のような電圧減殺素子を設置できるように構成することにより明るさの調節が容易な安定器を有する蛍光灯用のＬＥＤ照明灯に関するものである。   The present invention also relates to an LED illumination lamp for a fluorescent lamp having a ballast that can be easily adjusted in brightness by being configured so that a voltage reducing element such as a Zener diode can be installed instead of an LED.

白熱電球と比べて眩しさが少なく、発光効率が高く、寿命が長いために多く使用されている照明器具のうちの一つが蛍光灯である。   Fluorescent lamps are one of the lighting fixtures that are often used because they have less glare than incandescent bulbs, have high luminous efficiency, and have a long lifetime.

この蛍光灯は、気体や気体内の放電による光を光源として利用するものであり、真空ガラス管に少量の水銀蒸気と放電し易くするためのアルゴンガスを入れて密閉させた後、両端に電極を設けて構成されている。   This fluorescent lamp uses gas or light from the discharge in the gas as a light source. After a small amount of mercury vapor and argon gas are placed in a vacuum glass tube for easy discharge, it is sealed at both ends. Is provided.

このように構成された蛍光灯は、白熱電球に比べて熱による損失が少なくて効率が高く、寿命も長い。   The fluorescent lamp configured in this manner has less loss due to heat and higher efficiency than an incandescent lamp, and has a long life.

このような蛍光灯は、負性抵抗特性を有する水銀放電管の一種であり、電源だけ供給する場合、点灯されずに点灯を誘導し、点灯後に安定的に電源を供給するための手段として安定器が具備されている。   Such a fluorescent lamp is a kind of mercury discharge tube having a negative resistance characteristic. When only power is supplied, the fluorescent lamp is not lit but induces lighting without being turned on, and is stable as a means for stably supplying power after lighting. A vessel is provided.

即ち、安定器を設置して、初めは蛍光灯の点灯に必要な放電開始用の高電圧を印加し、点灯後に安定的な電圧と電流が供給されるようになっている。   That is, a ballast is installed, and a high voltage for starting discharge necessary for lighting a fluorescent lamp is first applied, and a stable voltage and current are supplied after lighting.

このように構成された蛍光灯は、上記のように真空ガラス管を利用して構成されていることにより、製造時に真空ガラス管を十分に密閉しなければならないため、製作上の多くの難点があるだけでなく、突発的に点灯されない場合があり、寿命がほとんど尽きた場合にチラツキ等が生じてしまうという問題もあった。   Since the fluorescent lamp configured as described above is configured by using the vacuum glass tube as described above, the vacuum glass tube must be sufficiently sealed at the time of manufacture. In addition, there is a problem that the light may not be suddenly lit and flickering may occur when the life is almost exhausted.

また、蛍光灯から発生する光は、色褪を生じさせたり劣化させる紫外線を含んでいるため、冷蔵庫などに使用する場合、食品を劣化させてしまうという問題があった。   In addition, since the light generated from the fluorescent lamp contains ultraviolet rays that cause or deteriorate the color fading, there is a problem that the food is deteriorated when used in a refrigerator or the like.

その他にも、頻繁なスイッチング作動が行われる場合、寿命が急激に短縮されたり、消費電力が多くなったりするという問題があった。   In addition, when a frequent switching operation is performed, there is a problem that the lifetime is rapidly shortened or the power consumption is increased.

このため、ＬＥＤを利用した蛍光灯が開発・使用されており、このようなＬＥＤを利用した蛍光灯を構成する回路基板は、伝導性の金属ではなく絶縁体を使用しており、従来のＬＥＤ蛍光灯は、ＬＥＤから発生する熱を放出する効果が極めて低いため、長期間に亘って使用する際、ＬＥＤから発生する熱による密閉されたハウジング内部の過熱によって、ハウジング外形の変形及びＬＥＤの効率の急激な低下が生じ、ＬＥＤ蛍光灯の寿命を短縮させてしまうという問題があった。   For this reason, fluorescent lamps using LEDs have been developed and used, and circuit boards that make up such fluorescent lamps using LEDs use insulators instead of conductive metals. Since the fluorescent lamp has an extremely low effect of releasing heat generated from the LED, when it is used for a long period of time, deformation of the outer shape of the housing and efficiency of the LED are caused by overheating inside the sealed housing due to heat generated from the LED. There has been a problem that the rapid decrease of the LED occurs and the life of the LED fluorescent lamp is shortened.

本発明の目的は、前述したような従来の技術の問題点を解決することであり、真空を要しないために製作が容易であり、突発的な不良を減らすことができ、寿命末期のチラツキがなく、特に、既存の蛍光灯ソケットに設置可能な安定器を有する蛍光灯用のＬＥＤ照明灯を提供することである。   The object of the present invention is to solve the problems of the prior art as described above, and since it does not require a vacuum, it is easy to manufacture, can reduce sudden failures, and flickers at the end of its life. In particular, an LED illumination lamp for a fluorescent lamp having a ballast that can be installed in an existing fluorescent lamp socket is provided.

更に、本発明の目的は、ＬＥＤから発生する熱を効率的に放出させることによって、ハウジングの変形等を防止するだけでなく、ＬＥＤの効率の低下を回避し、所望の照度に調節し易い安定器を有する蛍光灯用のＬＥＤ照明灯を提供することである。   Furthermore, the object of the present invention is not only to prevent the deformation of the housing by efficiently releasing the heat generated from the LED, but also to avoid a decrease in the efficiency of the LED and to easily adjust to a desired illuminance. It is providing the LED illumination light for fluorescent lamps which has a vessel.

また、少ない電力で作動して電力消費を低減し、頻繁なスイッチング作動にも寿命が短縮されない安定器を有する蛍光灯用のＬＥＤ照明灯を提供することを目的とする。   It is another object of the present invention to provide an LED lighting for a fluorescent lamp that has a ballast that operates with a small amount of power to reduce power consumption and does not have a shortened life even with frequent switching operations.

このような本発明の目的を達成するための安定器を有する蛍光灯用のＬＥＤ照明灯は、安定器を具備した蛍光灯ソケットに取付けられる照明灯において、基板に多数のＬＥＤを接続して構成された発光本体と、前記安定器の出力電源を直流電源に変換させる変換器と、発光本体に面する側面に形成されて発光本体を固定する基板固定溝と反対側の側面に形成される多数の放熱羽とを有して発光本体から発生する熱を放出する放熱板と、変換器の変換回路と接続されて発光本体の両端に固定されて蛍光灯ソケットに突出状態で取付けられる電極端子を有する端子キャップを備えていることを特徴とする。   An LED illuminating lamp for a fluorescent lamp having a ballast for achieving the object of the present invention is configured by connecting a large number of LEDs to a substrate in an illuminating lamp attached to a fluorescent lamp socket equipped with a ballast. A light emitting body, a converter for converting the output power of the ballast to a DC power source, and a plurality of parts formed on a side surface opposite to a substrate fixing groove formed on a side surface facing the light emitting body and fixing the light emitting body. A heat sink that releases heat generated from the light emitting body, and an electrode terminal that is connected to the conversion circuit of the converter and fixed to both ends of the light emitting body and attached to the fluorescent lamp socket in a protruding state. A terminal cap is provided.

本発明は、多数のＬＥＤを配列して構成されているため、真空状態を必要とすることなく製作が容易であり、突発的な不良を低減でき、寿命末期のチラツキを回避できる。   Since the present invention is configured by arranging a large number of LEDs, it can be easily manufactured without requiring a vacuum state, sudden failures can be reduced, and flicker at the end of life can be avoided.

特に、既存の蛍光灯ソケットに設置可能なため、ソケットの交換を必要とすることなく使用でき、ソケット設置費用を節減できる。   In particular, since it can be installed in an existing fluorescent lamp socket, it can be used without requiring replacement of the socket, and the socket installation cost can be reduced.

また、本発明の照明灯を構成するＬＥＤを多数一組で構成し、これを並列に連結するだけでなく、一部のＬＥＤをツェナーダイオード等のような発光機能のないダイオードに替えて構成しているため、光の明るさを自由に調節できる。   In addition, the LED constituting the illuminating lamp of the present invention is configured as a set of many, and not only is this connected in parallel, but also a part of the LED is replaced with a diode having no light emitting function such as a Zener diode. The brightness of the light can be adjusted freely.

また、少ない電力で作動することが可能なため、電力消費を減らすことができ、頻繁なスイッチング作動にも寿命の短縮がなく長期間に亘って使用することができる。   In addition, since it is possible to operate with a small amount of electric power, power consumption can be reduced, and frequent switching operations can be used over a long period of time without shortening the lifetime.

図１に示すように、本発明の安定器を有する蛍光灯用のＬＥＤ照明灯は、ＬＥＤ１２の設置された基板１１にて構成された発光本体１を安定器１００（図８を参照）を具備したソケットに取り付け、ＬＥＤ１２に電源を供給するように構成されている。   As shown in FIG. 1, an LED illuminating lamp for a fluorescent lamp having a ballast according to the present invention includes a light emitting body 1 composed of a substrate 11 on which an LED 12 is installed, and a ballast 100 (see FIG. 8). It is configured to be attached to the socket and to supply power to the LED 12.

即ち、本発明のＬＥＤ照明灯は、安定器１００（図８を参照）を具備した蛍光灯ソケットに取付けられ、基板１１に多数のＬＥＤ１２を接続して構成される発光本体１と、安定器１００（図８を参照）の出力電源を直流電源に変換させる変換器２と、発光本体１に面する側面に発光本体１を固定する基板固定溝３１を有するとともに反対側の側面に多数の放熱羽３３を有して発光本体１から発生する熱を放出する放熱板３と、変換器２の変換回路と接続されるとともに、発光本体１の両端に固定されて蛍光灯ソケットに取付けられた電極端子４１を突出状態で有する端子キャップ４とを備えている。   That is, the LED illuminating lamp of the present invention is attached to a fluorescent lamp socket having a ballast 100 (see FIG. 8), and the light emitting body 1 configured by connecting a number of LEDs 12 to the substrate 11, and the ballast 100. A converter 2 that converts the output power source (see FIG. 8) into a DC power source, a substrate fixing groove 31 that fixes the light emitting body 1 on the side surface facing the light emitting body 1, and a large number of radiating blades on the opposite side surface The electrode terminal which is connected to the heat radiation plate 3 which releases heat generated from the light emitting body 1 and the converter 2 and which is fixed to both ends of the light emitting body 1 and attached to the fluorescent lamp socket And a terminal cap 4 having 41 in a protruding state.

発光本体１は、図１及び図２に示すように、基板１１の底面、即ち、光を照射する面に多数のＬＥＤ１２を設置しており、このような基板１１は、図６に示すように、多数に分離して構成しても良い。   As shown in FIGS. 1 and 2, the light emitting body 1 has a large number of LEDs 12 installed on the bottom surface of the substrate 11, that is, the surface that irradiates light. Alternatively, a large number of parts may be separated.

本発明のＬＥＤ照明灯を構成する基板１１は、アルミニウムからなるＰＣＢ（ｐｒｉｎｔｅｄ ｃｉｒｃｕｉｔ ｂｏａｒｄ）にて構成されており、こうしてアルミニウムからなるＰＣＢで基板１１を構成することによって、ＬＥＤ１２の発光時に発生する熱をより早く放熱させ、ＬＥＤ１２の過熱を防止することはもちろん、照明灯を構成する他の構成要素の変形を防止することができる。   The substrate 11 constituting the LED illumination lamp of the present invention is composed of a PCB (printed circuit board) made of aluminum. Thus, by forming the substrate 11 with a PCB made of aluminum, heat generated when the LED 12 emits light. Can be dissipated faster and the LED 12 can be prevented from overheating, as well as deformation of other components constituting the illuminating lamp.

即ち、従来のＬＥＤ照明灯の場合、基板として絶縁体を使用しており、このように絶縁体を使用した場合、ＬＥＤから発生する熱を放出する効果が極めて低く、このため、ＬＥＤ照明灯を長期間続けて点灯する際、ＬＥＤから発生する熱によってハウジングが過熱され、ハウジングの外形変形はもちろん、ＬＥＤ効率が急激に低下し、ＬＥＤ照明灯の寿命が短縮されるという問題があった。   That is, in the case of a conventional LED lighting, an insulator is used as a substrate. When an insulator is used in this way, the effect of releasing heat generated from the LED is extremely low. When lighting continuously for a long period of time, the housing is overheated by the heat generated from the LED, and there is a problem that the LED efficiency is abruptly lowered as well as the outer shape of the housing, and the life of the LED lighting lamp is shortened.

そこで、本発明は、熱伝導率の高いアルミニウムからなるＰＣＢを使用して熱を早く外部へ放出させ、熱によるハウジングの変形やＬＥＤ１２の効率低下を防止することができる。   Therefore, according to the present invention, heat is quickly released to the outside by using a PCB made of aluminum having a high thermal conductivity, so that deformation of the housing due to heat and reduction in efficiency of the LED 12 can be prevented.

基板１１には、図７及び図８に示すように、ＬＥＤ１２に電源を供給するための回路パターン１３が形成されている。   As shown in FIGS. 7 and 8, a circuit pattern 13 for supplying power to the LEDs 12 is formed on the substrate 11.

特に、本発明のＬＥＤ照明灯を構成する回路パターン１３は、図示すように、基板１１の端に沿って長さ方向に長く形成されたＧＮＤパターン及びＶｃｃパターンと、ＧＮＤパターン及びＶｃｃパターンの間に形成されたＬＥＤ接続部１３ａ及び短絡部１３ｂ及びＬＥＤブロック１３ｃとにより構成されている。   In particular, the circuit pattern 13 constituting the LED lighting lamp of the present invention has a GND pattern and a Vcc pattern formed long in the length direction along the edge of the substrate 11, and a GND pattern and a Vcc pattern, as shown in the figure. The LED connection portion 13a, the short-circuit portion 13b, and the LED block 13c are formed.

ＬＥＤブロック１３ｃは、多数のＬＥＤ１２を相互に直列に連結できるように形成された導電性パターンであり、ＬＥＤ１２を一個から数十個まで直列に連結でき、このような直列連結が可能なＬＥＤ１２の数は、蛍光灯の安定器１００の種類や容量によって異なるため、これを制限することはできない。   The LED block 13c is a conductive pattern formed so that a large number of LEDs 12 can be connected to each other in series. One to several tens of LEDs 12 can be connected in series, and the number of LEDs 12 that can be connected in series. Is different depending on the type and capacity of the fluorescent lamp ballast 100, and cannot be limited.

上述したように、基板１１を多数に分離して構成する理由は、通常の蛍光灯の長さが多様であり、長いものは１．２ｍにもなるからである。   As described above, the reason why the substrate 11 is divided into a large number is that the lengths of ordinary fluorescent lamps are various, and long ones can be as long as 1.2 m.

このような長い蛍光灯を使用するソケットに設置することのできるＬＥＤ照明灯を製作する時、単一の基板１１で製作した場合、全長が長すぎて変形の恐れがあるだけでなく、製作も難しいという問題があるため、図６に示すように、基板１１を多数に分離して製作し、連結部をハンダ付けで連結して一体化するのが好ましい。   When manufacturing an LED illuminating lamp that can be installed in a socket that uses such a long fluorescent lamp, if it is manufactured with a single substrate 11, the total length is too long and there is a risk of deformation, as well as manufacturing. Since there is a problem that it is difficult, as shown in FIG. 6, it is preferable to manufacture the substrate 11 by separating it into a large number, and to connect and integrate the connecting portions by soldering.

多数に分離された基板１１を電気的に接続する時は、フィルムケーブル又は一般的な被覆タイプのケーブルを使用しても良く、基板１１間の間隔を狭めた後、直接的にハンダ付けのみで基板１１間を電気的に接続しても良い。   When electrically connecting a large number of separated substrates 11, film cables or general coated type cables may be used. After narrowing the distance between the substrates 11, only by soldering directly. The substrates 11 may be electrically connected.

また、アルミニウムからなるＰＣＢにて構成された基板１１は、ＬＥＤ１２の設置される前面部を白又は反射が容易な色でペインティング又はコーティングして光を外部に反射することにより、効率を最大限に高めることができる。   In addition, the substrate 11 made of PCB made of aluminum maximizes efficiency by painting or coating the front part where the LED 12 is installed with white or an easily reflective color to reflect light to the outside. Can be increased.

一方、短絡部１３ｂは、ＬＥＤブロック１３ｃの間、ＬＥＤブロック１３ｃとＧＮＤパターンとの間、ＬＥＤブロック１３ｃとＶｃｃパターンとの間を短絡するように形成されている。   On the other hand, the short circuit part 13b is formed so as to short circuit between the LED block 13c, between the LED block 13c and the GND pattern, and between the LED block 13c and the Vcc pattern.

このように形成された短絡部１３ｂを選択的に通電することで、各ＬＥＤブロック１３ｃは、相互に直列又は並列に連結されている。   By selectively energizing the short-circuit portion 13b thus formed, the LED blocks 13c are connected in series or in parallel to each other.

この時、短絡部１３ｂを通電する方法は、フィルムケーブル又は一般的な被覆タイプのケーブルを連結したり、ハンダを広く広げてハンダ付けする等の方法を利用することができ、電気素子として０Ω（ｏｈｍ）の抵抗を利用することができる。   At this time, as a method of energizing the short-circuit portion 13b, a method such as connecting a film cable or a general coated type cable, or widening and soldering a solder can be used. ohm) resistance can be used.

このように選択的に通電され得るように短絡部１３ｂを構成したのは、安定器１００から出力される電流と電圧がＬＥＤ１２の特性をオーバーしてＬＥＤ１２の寿命を縮めるという欠点を改善し、ＬＥＤ１２の破損を防止するためである。
即ち、多様な種類の安定器１００に合わせて選択的にＬＥＤ１２の接続数を調節できるようにするためである。 The short-circuit portion 13b is configured to be selectively energized in this way, which improves the disadvantage that the current and voltage output from the ballast 100 exceed the characteristics of the LED 12 and shorten the life of the LED 12. This is to prevent damage to the machine.
That is, the number of connected LEDs 12 can be selectively adjusted according to various types of ballasts 100.

また、本発明の実施例では照明灯としてのＬＥＤ１２を利用したが、変形例としてＬＥＤ１２の代わりに非発光性のツェナーダイオードを設置して発光量を調節しても良い。   In the embodiment of the present invention, the LED 12 is used as an illuminating lamp. However, as a modification, a light emitting amount may be adjusted by installing a non-light emitting Zener diode instead of the LED 12.

即ち、照明の設置場所が過度に明るさを必要としない場所である場合、安定器１００から供給される電源は一定しているため、これを消費させねばならず、これを消費させるためにツェナーダイオードをＬＥＤ１２の代わりに設置して構成している。   That is, when the installation location of the lighting does not require excessive brightness, since the power supplied from the ballast 100 is constant, it must be consumed, and the Zener is required to consume it. A diode is installed instead of the LED 12.

このような場合、必要なＬＥＤ１２を先に配置し、足りないＬＥＤ１２の数に該当するツェナーダイオード又は電圧を減殺させる電子部品をＬＥＤ１２の搭載位置に代替搭載して安定器の特性に合致させ、ＬＥＤ１２を点灯するようになっている。   In such a case, the necessary LEDs 12 are arranged first, and Zener diodes corresponding to the number of the missing LEDs 12 or electronic components for reducing the voltage are alternatively mounted at the mounting positions of the LEDs 12 to match the characteristics of the ballasts. Lights up.

この時に使用するツェナーダイオード及び電子部品は、ＳＭＤタイプのＬＥＤ１２とサイズが同じであるか、搭載可能なサイズでなければならず、適切な部品がない場合、他の形態の部品を選定して使用しても良い。   The Zener diode and electronic components used at this time must be the same size as the SMD type LED 12 or be of a size that can be mounted. If there are no suitable components, select and use other types of components. You may do it.

また、発光本体１は、図８に示すように、第一発光部１ａと第二発光部１ｂを相互に並列に連結し、第一発光部１ａ及び第二発光部１ｂと安定器１００との間に変換器２をそれぞれ連結して構成しても良い。   Further, as shown in FIG. 8, the light emitting body 1 connects the first light emitting unit 1a and the second light emitting unit 1b in parallel to each other, and the first light emitting unit 1a, the second light emitting unit 1b, and the ballast 100 are connected. The converters 2 may be connected in between.

このように第一発光部１ａと第二発光部１ｂとを並列に連結して単一の発光本体１を構成することにより、一方の発光部が故障を起した場合であっても、他方の発光部によって照明を行うことができる。   Thus, by connecting the first light emitting unit 1a and the second light emitting unit 1b in parallel to form a single light emitting body 1, even if one light emitting unit fails, the other Illumination can be performed by the light emitting unit.

上記のように構成された発光本体１に整流された電源を供給する変換器２は、図１及び図２及び図５に示すように、端子キャップ４の内部に設置され、図８に示すように構成されている。   The converter 2 for supplying rectified power to the light emitting body 1 configured as described above is installed inside the terminal cap 4 as shown in FIGS. 1, 2 and 5, and as shown in FIG. It is configured.

このように変換器２の設置された端子キャップ４の内部は、図示するようにコーティング材４２にてモールディングされて回路を保護するようになっており、電極端子４１を露出した部分の外径が、発光本体１と連結される部分の外径より小さく形成されて既存の蛍光灯ソケットに容易に差し込めるようになっている。   Thus, the inside of the terminal cap 4 in which the converter 2 is installed is molded with the coating material 42 to protect the circuit as shown in the figure, and the outer diameter of the portion where the electrode terminal 41 is exposed is The outer diameter of the portion connected to the light emitting body 1 is smaller than the outer diameter so that it can be easily inserted into an existing fluorescent lamp socket.

端子キャップ４の内側に延長された電極端子４１の端部は、変換器２に構成された回路と電気的に接続された状態になるようにハンダ付け４１ａされている。   An end portion of the electrode terminal 41 extended to the inside of the terminal cap 4 is soldered 41a so as to be in a state of being electrically connected to a circuit configured in the converter 2.

変換器２は、図８に示すように、放電器としての安定器１００から供給される交流を直流に変換するためのブリッジ整流回路２ａと、ブリッジ整流回路２ａの入力端に並列連結された抵抗２ｂと、ブリッジ整流回路２ａの出力端に並列連結されたコンデンサー２ｃとで構成されている。   As shown in FIG. 8, the converter 2 includes a bridge rectifier circuit 2a for converting alternating current supplied from a ballast 100 as a discharger into direct current, and a resistor connected in parallel to the input terminal of the bridge rectifier circuit 2a. 2b and a capacitor 2c connected in parallel to the output terminal of the bridge rectifier circuit 2a.

ここで、ブリッジ整流回路２ａを構成するダイオードとして、高周波用ダイオードを使用している。   Here, a high-frequency diode is used as the diode constituting the bridge rectifier circuit 2a.

電子式の安定器１００の場合、６０Ｈｚの常用電源を高周波（数十ＫＨｚ）で出力するようになっている。
このような高周波電流及び電圧は、過電圧保護のためのヒューズ（ＦＵＳＥ）を設置した後、このヒューズを通過してダイオードを介して直流に変換されるが、この時に使用するダイオードの部品として一般汎用ダイオードを使用した場合、部品に熱が発生して破損される可能性があるため、高周波用ダイオードにて構成するのが好ましい。 In the case of the electronic ballast 100, a normal power supply of 60 Hz is output at a high frequency (several tens of KHz).
Such a high-frequency current and voltage are converted into direct current through a diode after passing a fuse (FUSE) for overvoltage protection. When a diode is used, heat may be generated in the component and it may be damaged. Therefore, it is preferable to use a high-frequency diode.

変換器２の出力の安定化のために、直流変換の最終端、即ち、ブリッジ整流回路２ａの出力端にコンデンサー２ｃを更に並列に設置して電圧を安定化させている。   In order to stabilize the output of the converter 2, a capacitor 2c is further arranged in parallel at the final end of the direct current conversion, that is, the output end of the bridge rectifier circuit 2a to stabilize the voltage.

上記では本発明のＬＥＤ照明灯の主要構成要素である発光本体１と電源供給手段である変換器２の構成に関して説明したが、以下に、これら構成要素を相互に連結するとともに発光本体１の熱を放熱するための構成要素である放熱板３と、保護手段である２つの正面カバー５及び背面カバー６とに関して詳しく説明する。   In the above description, the configuration of the light-emitting body 1 which is a main component of the LED lighting lamp of the present invention and the converter 2 which is a power supply means have been described. The heat radiating plate 3 that is a component for radiating heat and the two front covers 5 and the back cover 6 that are protective means will be described in detail.

放熱板３は、発光本体１の熱を外部に放出する役割と同時に、発光本体１の形状を維持する骨組みの役割を果たしている。   The heat radiating plate 3 plays the role of a framework for maintaining the shape of the light emitting body 1 at the same time as releasing the heat of the light emitting body 1 to the outside.

このような放熱板３には、図１及び図２に示すように、発光本体１に面する側面に発光本体１を安着する基板固定溝３１が形成されており、反対側の側面に多数の放熱羽３３が形成されている。   As shown in FIGS. 1 and 2, the heat sink 3 is formed with a substrate fixing groove 31 for seating the light emitting body 1 on the side surface facing the light emitting body 1, and a large number on the opposite side surface. Are formed.

放熱板３に形成された放熱羽３３の表面には、放熱効果を高めるために凹凸３３ａが更に形成されている。
即ち、放熱板３に伝達された基板１１の熱をより早く外部に伝達されるためには放熱面積が広くなければならず、そのため、放熱羽３３の外面に多数の凹凸３３ａを形成して放熱面積を広くしている。 On the surface of the heat radiating blade 33 formed on the heat radiating plate 3, unevenness 33a is further formed in order to enhance the heat radiating effect.
That is, in order to transfer the heat of the substrate 11 transmitted to the heat radiating plate 3 to the outside more quickly, the heat radiating area must be large. The area is widened.

また、放熱板３には、上述したように正面カバー５と背面カバー６とが固定されており、このように２つの正面カバー５及び背面カバー６を固定するための構造として、放熱板３の両端には、掛け部３５が形成されて正面カバー５の両端に形成された放熱板挿入溝５３に差し込まれて結合されている。   Further, as described above, the front cover 5 and the back cover 6 are fixed to the heat radiating plate 3. As a structure for fixing the two front covers 5 and the back cover 6 as described above, Hang portions 35 are formed at both ends, and are inserted into and coupled to heat sink insertion grooves 53 formed at both ends of the front cover 5.

また、背面カバー６を固定させる手段として、放熱板３の背面に形成された放熱羽３３のうち本体部と垂直をなして形成された放熱羽３３の端部には、背面カバー６の中央に形成された放熱板挿入溝６３に差し込まれる掛け羽３６が形成されている。   Further, as a means for fixing the back cover 6, the end of the heat radiating feather 33 formed perpendicular to the main body portion of the heat radiating feather 33 formed on the back surface of the heat radiating plate 3 is placed at the center of the back cover 6. A hanging blade 36 to be inserted into the formed heat sink insertion groove 63 is formed.

このような２つの正面カバー５及び背面カバー６の結合方法を簡単に説明すると、まず、掛け部３５の端部に放熱板挿入溝５３の端部を対向させ、正面カバー５を押して掛け部３５を放熱板挿入溝５３に差し込んで固定する。   The method of joining the two front covers 5 and the back cover 6 will be described briefly. First, the end of the heat sink insertion groove 53 is opposed to the end of the hook 35, and the front cover 5 is pushed to press the hook 35. Is inserted into the heat sink insertion groove 53 and fixed.

そして、掛け羽３６の端部を放熱板挿入溝６３の端部に対向させた後、背面カバー６を押して掛け羽３６を放熱板挿入溝６３に差し込むことで、放熱板３と２つの正面カバー５及び背面カバー６とを相互に結合する。   And after making the edge part of the hanging blade 36 oppose the edge part of the heat sink insertion groove | channel 63, the rear cover 6 is pushed and the hanging blade 36 is inserted in the heat sink insertion groove | channel 63, thereby the heat radiation plate 3 and the two front covers. 5 and the back cover 6 are coupled to each other.

一方、正面カバー５に形成された光拡散凹凸５２は、正面カバー５の内面に形成されたものを一例として図示しているが、外面に形成しても良く、この光拡散凹凸５２は、ＬＥＤ１２から照射された光を拡散させてより明るく見えるようにする効果を有している。   On the other hand, although the light diffusion unevenness 52 formed on the front cover 5 is illustrated as an example formed on the inner surface of the front cover 5, it may be formed on the outer surface. It has the effect of diffusing the light irradiated from, making it appear brighter.

この光拡散凹凸５２は、図示するように外形上カバーとしての正面カバー５の長さ方向に長く形成しても良いが、半球形状の突起を稠密に形成して構成しても良い。   The light diffusion unevenness 52 may be formed long in the length direction of the front cover 5 as an outer cover as shown in the figure, but may be configured by forming hemispherical projections densely.

背面カバー６は、前述したように放熱板３の外面を覆って、加熱された放熱板３が人体と接触することを防止する機能を有し、また、放熱板３全体を覆うと放熱板３の放熱効果が落ちる可能性があるため、図１及び図２及び図４に示すように、放熱板３の一部だけを覆うように設置している。






As described above, the back cover 6 has a function of covering the outer surface of the heat sink 3 and preventing the heated heat sink 3 from coming into contact with the human body. Therefore, as shown in FIGS. 1, 2, and 4, it is installed so as to cover only a part of the heat radiating plate 3.
