Description

本発明は、既存の予熱回路を備えた蛍光灯器具に取り付けでき、取り付け交換時の感電を効果的に防止できる、LED蛍光灯(または蛍光灯型LED)に関する。   The present invention relates to an LED fluorescent lamp (or a fluorescent lamp-type LED) that can be attached to a fluorescent lamp fixture having an existing preheating circuit and can effectively prevent an electric shock at the time of replacement.

現在、白熱電球や蛍光灯などの既存光源をLED(発光ダイオード)に交換、置き換える動きが広がっている。LEDを光源とすることにより、既存光源よりも長寿命かつ省エネルギーの照明器具とすることが出来る為である。   Currently, there is a growing movement to replace and replace existing light sources such as incandescent bulbs and fluorescent lamps with LEDs (light emitting diodes). This is because by using the LED as the light source, it is possible to provide a lighting device having a longer life and energy saving than the existing light source.

蛍光灯の点灯方式としては、グロースタータ方式、ラピッドスタート方式、およびインバータ方式、の3方式に大別され、器具内にこれらいずれかの点灯回路が組み込まれている。
このような蛍光灯器具をLEDに置き換えるには、(1)器具そのもの、または器具に組み込まれた点灯回路をLED用の点灯回路に交換・改造する方法、(2)蛍光灯に模したLED蛍光灯の内部に点灯回路を配置し、光源のみをLED蛍光灯と置換える方法、などが提案されている。前者の方法では器具を施工、改造することとなるため、一般消費者が交換することは技術的、金銭的な困難さがある。一方で後者の方法では、形状、電極端子などを蛍光灯器具に適合させたLED蛍光灯を従来の蛍光灯と交換するだけのため、(1)の方法より導入しやすいなどの利点がある(例えば先行技術1〜3を参照)。
Fluorescent lamp lighting methods are roughly classified into three methods, a glow starter method, a rapid start method, and an inverter method, and any one of these lighting circuits is incorporated in the fixture.
In order to replace such a fluorescent lamp fixture with an LED, (1) a method of replacing or remodeling the fixture itself or a lighting circuit incorporated in the fixture with a lighting circuit for LED, (2) LED fluorescence imitating a fluorescent lamp A method of arranging a lighting circuit inside a lamp and replacing only a light source with an LED fluorescent lamp has been proposed. Since the former method involves construction and modification of equipment, it is technically and financially difficult for a general consumer to replace it. On the other hand, the latter method has an advantage that it is easier to introduce than the method (1) because the LED fluorescent lamp whose shape, electrode terminal and the like are adapted to the fluorescent lamp fixture is simply replaced with the conventional fluorescent lamp ( For example, see prior art 1-3).

特許3929885Patent 3929885 特開2008−277188JP 2008-277188 A 特開2009−266696JP2009-266696A

しかし(2)の方法では、点灯回路をLED蛍光灯内に配するため、例えば器具に通電したまま蛍光灯の交換を行ってしまった場合、従来の蛍光灯の交換と比べて感電のリスクが高い。これは従来の蛍光灯が口金に接続されたフィラメントの間の放電により点灯するのに対し、LED蛍光灯は口金に接続されたLEDに通電させて点灯させるためである。言い換えれば、放電前の非点灯時では内部抵抗が大きい蛍光灯に対し、LED蛍光灯は非点灯時でも内部抵抗が低く、一方の口金を器具に装着した際、他端の口金にまで電圧が印加されてしまうためである。このため交換時、他端側の口金に触れてしまうと感電のリスクがある。   However, in the method (2), since the lighting circuit is arranged in the LED fluorescent lamp, for example, if the fluorescent lamp is replaced while the appliance is energized, there is a risk of electric shock compared to the conventional fluorescent lamp replacement. high. This is because the conventional fluorescent lamp is turned on by discharge between the filaments connected to the base, whereas the LED fluorescent lamp is turned on by energizing the LED connected to the base. In other words, the LED fluorescent lamp has a low internal resistance even when it is not lit, when the lamp is not lit before discharge, and the internal resistance is low. This is because it is applied. For this reason, there is a risk of electric shock if the base on the other end is touched during replacement.

また一方で上述の3通りの点灯方式のうち、最も構成が簡単で安価のグロースタータ方式の器具数は、日本では減少しているものの海外では主流の点灯方式である。このためLED化が急速に進んでいる現在、器具の改造を必要とせず、消費者を問わず誰でも簡単に国内外で実施できる、グロースタータ方式に適合したLED蛍光灯の仕様の開発は急務である。   On the other hand, among the three lighting methods described above, the number of fixtures of the glow starter method, which is the simplest and cheapest, is the mainstream lighting method overseas although it is decreasing in Japan. For this reason, with the rapid development of LEDs, there is an urgent need to develop specifications for LED fluorescent lamps suitable for the glow starter method that can be easily implemented at home and abroad by anyone, regardless of the consumer, without requiring remodeling of equipment. It is.

以上より本発明の課題は、グロースタータ方式の既存の蛍光灯を、感電の恐れがなく、誰でも容易に、LED蛍光灯と交換できる仕様を提供することである。   As described above, an object of the present invention is to provide a specification that allows anyone to easily replace an existing fluorescent lamp of the glow starter type with an LED fluorescent lamp without fear of electric shock.

本発明は、グロースタータ方式の蛍光灯器具において、既存の直管型蛍光灯を、一端側に給電側口金、他端側に内部短絡された短絡側口金を備えるLED蛍光灯と交換し、さらに既存のグロー管をLED用点灯管と交換する、ことを最も主要な特徴とする。   The present invention relates to a glow starter type fluorescent lamp apparatus, in which an existing straight tube type fluorescent lamp is replaced with an LED fluorescent lamp having a power supply side base on one end side and a short side base internally short-circuited on the other end side, The most important feature is that the existing glow tube is replaced with an LED lighting tube.

本発明のLED蛍光灯器具によれば、既存の蛍光灯とグロー管(点灯管)を交換するのみのため、誰でも容易に交換作業を行うことができる。また一端側からのみLED蛍光灯に給電し、かつ他端側が内部短絡されることで、両端の端子間が回路的に絶縁され、例えば一端側の端子を器具に取り付けた際、他端側に電圧が印加される恐れがなく、交換作業時の感電のリスクが飛躍的に低減する。   According to the LED fluorescent lamp apparatus of the present invention, since only the existing fluorescent lamp and the glow tube (lighting tube) are replaced, anyone can easily perform the replacement operation. In addition, power is supplied to the LED fluorescent lamp only from one end side, and the other end side is internally short-circuited, so that the terminals at both ends are insulated in a circuit. For example, when the terminal on one end side is attached to the instrument, There is no risk of voltage being applied, and the risk of electric shock during replacement work is drastically reduced.

本発明のLED蛍光灯器具10は、LED蛍光灯2、LED用点灯管3、およびこれらを取り付けるための器具1からなる。図1にその外観模式図を、図2にその回路構成の模式図を示す。本実施例においては、LED蛍光灯器具10は直管型の器具である。また図3に、本発明のLED蛍光灯2とLED用点灯管3との交換する前の、従来の蛍光灯20、グロー管30を取り付けた状態の回路の模式図を示す。さらに図4に、本発明のLED蛍光灯2の長手方向断面の模式図を示す。   The LED fluorescent lamp fixture 10 of the present invention includes an LED fluorescent lamp 2, an LED lighting tube 3, and an appliance 1 for mounting them. FIG. 1 shows a schematic diagram of its appearance, and FIG. 2 shows a schematic diagram of its circuit configuration. In this embodiment, the LED fluorescent lamp device 10 is a straight tube type device. FIG. 3 shows a schematic diagram of a circuit with a conventional fluorescent lamp 20 and a glow tube 30 attached before the replacement of the LED fluorescent lamp 2 and the LED lighting tube 3 of the present invention. Furthermore, in FIG. 4, the schematic diagram of the longitudinal direction cross section of the LED fluorescent lamp 2 of this invention is shown.

図3に示したよう、グロースタータ方式の点灯回路は主に、蛍光灯20、グロー管30、安定器40により構成される。スイッチ60により電源が入ると、グロー管30の内部で放電し、この熱によりグロー管30内部のバイメタルが作動し電流が流れる。この際、蛍光灯20の両端のフィラメントが予熱される。この間にバイメタルの冷却に伴い、グロー管30内部の回路が開いて電流が流れなくなる。すると安定器のキック電圧が生じて高電圧が生じ、両フィラメント間で放電することで蛍光管20が発光する。   As shown in FIG. 3, the glow starter type lighting circuit mainly includes a fluorescent lamp 20, a glow tube 30, and a ballast 40. When the power is turned on by the switch 60, electric discharge is generated inside the glow tube 30, and this heat causes the bimetal inside the glow tube 30 to operate and current flows. At this time, the filaments at both ends of the fluorescent lamp 20 are preheated. During this time, with the cooling of the bimetal, the circuit inside the glow tube 30 opens and no current flows. Then, a kick voltage of the ballast is generated, a high voltage is generated, and the fluorescent tube 20 emits light by discharging between both filaments.

本発明のLED蛍光灯器具10は、蛍光灯20をLED蛍光灯2に、グロー管30をLED用点灯管3に交換することのみで構成される。LED蛍光灯2の口金21(21a、21b)とLED用点灯管3の口金は、容易に既存部品と交換可能なよう、蛍光灯20およびグロー管30とそれぞれ互換性のある同じ口金形状としている。このため他の部品、例えば器具1は既存の器具1をそのまま用いることができる。一般に蛍光灯20、グロー管30は、交換しやすいよう器具1の外側に表出して配置されており、上述の構成としていることで、誰でも簡単に交換作業を行うことができる。   The LED fluorescent lamp apparatus 10 of the present invention is configured only by replacing the fluorescent lamp 20 with the LED fluorescent lamp 2 and the glow tube 30 with the LED lighting tube 3. The cap 21 of the LED fluorescent lamp 2 (21a, 21b) and the cap of the LED lighting tube 3 have the same cap shape that is compatible with the fluorescent lamp 20 and the glow tube 30 so that they can be easily replaced with existing parts. Yes. For this reason, the existing instrument 1 can be used as it is for other parts, for example, the instrument 1. In general, the fluorescent lamp 20 and the glow tube 30 are arranged so as to be exposed on the outside of the instrument 1 so that they can be easily exchanged. With the above-described configuration, anyone can easily perform the exchange work.

まずはじめにLED蛍光灯20の詳細について説明する。
LED蛍光灯20は、一方向に長い直管形の蛍光灯と相似し互換性のある形状とされており、透明樹脂からなるカバー23と、後述するLED26の実装基板が搭載される放熱性の良い筐体24と、これらの両端に配置される口金21(21a、21b)とで外形が構成される。

またその内部に、点灯回路25、LED26、短絡部27を有する。点灯回路25は、ダイオードブリッジ回路からなる整流部25aと、整流された電流を平滑化しLED26に定電流を供給する電流調整部25bとからなる。なお短絡部27は、点灯回路25、LED26とは電気的に絶縁されている。
First, the details of the LED fluorescent lamp 20 will be described.
The LED fluorescent lamp 20 has a shape similar to and compatible with a straight tube fluorescent lamp that is long in one direction, and has a heat-dissipating property on which a cover 23 made of a transparent resin and a mounting board of an LED 26 described later are mounted. The outer shape is constituted by the good casing 24 and the caps 21 (21a, 21b) arranged at both ends thereof.

Moreover, it has the lighting circuit 25, LED26, and the short circuit part 27 in it. The lighting circuit 25 includes a rectification unit 25a formed of a diode bridge circuit, and a current adjustment unit 25b that smoothes the rectified current and supplies a constant current to the LED 26. Note that the short-circuit portion 27 is electrically insulated from the lighting circuit 25 and the LED 26.

カバー23はその断面が円弧状となるよう形成され、筐体24の長手方向に沿って設けられたガイド用の溝にスライドして固定される。またカバー23は透明なポリカーボネート樹脂からなり、LED26の光を拡散し、かつ使用者の感じるグレア感を低減させるため、その内面に光拡散処理を行っている。
カバー23は光劣化が少ない材料であればよく、ポリカーボネート樹脂のほかアクリル樹脂やシリコーン樹脂、ガラスなどを用いても良い。しかし一般に蛍光灯は口金端子のみで支持されることから軽量の部材が好ましく、樹脂で構成することが好ましい。さらに長尺状に成形する必要があることから、上記のうち熱可塑性樹脂であるポリカーボネート樹脂、アクリル樹脂のいずれかが好ましい。
また本実施例では、その内面に光拡散処理を行っているが、上記の材料にシリカや酸化チタンなど公知の光拡散材を混入し、光を拡散するようにしても良い。
The cover 23 is formed so as to have an arcuate cross section, and is slid and fixed in a guide groove provided along the longitudinal direction of the casing 24. Further, the cover 23 is made of a transparent polycarbonate resin, and a light diffusion process is performed on the inner surface of the cover 23 in order to diffuse the light of the LED 26 and reduce the glare feeling felt by the user.
The cover 23 may be made of a material with little light deterioration, and an acrylic resin, a silicone resin, glass or the like may be used in addition to the polycarbonate resin. However, since a fluorescent lamp is generally supported only by a base terminal, a lightweight member is preferable, and it is preferable to use a resin. Furthermore, since it is necessary to shape | mold in elongate shape, either the polycarbonate resin which is a thermoplastic resin among these, or an acrylic resin is preferable.
In this embodiment, the light diffusion treatment is performed on the inner surface, but a known light diffusion material such as silica or titanium oxide may be mixed into the above material to diffuse the light.

筐体24は熱伝導率の高いアルミからなり、LED26の実装基板の裏面と熱的に接続され、LED26で生じた熱をLED蛍光灯2の外部に放熱する。熱伝導率が高く放熱性の良い部材として、アルミ、銅などの金属、及びその合金や、セラミックスなどが挙げられる。しかし本発明においては、長尺状に成形する必要があることから、アルミ、銅、またはこれらを主成分とする合金で成形することが好ましい。   The housing 24 is made of aluminum having high thermal conductivity, and is thermally connected to the back surface of the mounting substrate of the LED 26, and dissipates heat generated by the LED 26 to the outside of the LED fluorescent lamp 2. Examples of members having high thermal conductivity and good heat dissipation include metals such as aluminum and copper, alloys thereof, and ceramics. However, in the present invention, since it is necessary to form in a long shape, it is preferable to form with aluminum, copper, or an alloy containing these as a main component.

点灯回路25は、図4に示したよう、LED蛍光灯2の一端側の給電側口金21a内に一対の端子と共に固定される。また短絡部27は、他端側の短絡側口金21b内で一対の端子間を短絡するように配置される。
ここで本実施例においては、点灯回路25および短絡部27と一対の端子が搭載された各回路基板は、LED26が配列実装された実装基板に対し略垂直となるよう、両口金21内にそれぞれ配置している。点灯回路25は、基板に占める実装面積よりも各素子の高さのほうが小さい場合があり、本構成によりLED26の実装面積をより広く、またはより多くのLED26を実装することが可能となる。このため、カバー23で規定される発光面積をより広く活用することができ、所望の照明光を得ることが容易となる。
また本実施例では、整流部25aと電流調整部25bとを給電側口金21a内に配置する例を示したが、平滑コンデンサなどを含む電流調整部25bの放熱性を高めるべく、電流調整部25bをLED26の実装基板側に配置してもよい。
As shown in FIG. 4, the lighting circuit 25 is fixed together with a pair of terminals in the power supply side base 21 a on one end side of the LED fluorescent lamp 2. Moreover, the short circuit part 27 is arrange | positioned so that a pair of terminals may be short-circuited in the short circuit side base 21b of the other end side.
Here, in the present embodiment, each circuit board on which the lighting circuit 25 and the short-circuit portion 27 and a pair of terminals are mounted is respectively placed in the both caps 21 so as to be substantially perpendicular to the mounting board on which the LEDs 26 are arranged and mounted. It is arranged. In the lighting circuit 25, the height of each element may be smaller than the mounting area occupying the substrate. With this configuration, the mounting area of the LEDs 26 can be larger, or more LEDs 26 can be mounted. For this reason, the light emission area prescribed | regulated with the cover 23 can be utilized more widely, and it becomes easy to obtain desired illumination light.
In the present embodiment, the example in which the rectifying unit 25a and the current adjusting unit 25b are disposed in the power supply side base 21a has been described. However, in order to improve the heat dissipation of the current adjusting unit 25b including a smoothing capacitor, the current adjusting unit 25b May be arranged on the mounting substrate side of the LED 26.

次に、LED用点灯管3について説明する。
LED用点灯管3は、その端子間が電気的に接続(導通)されている点で、従来のグロー管30とは異なる。本実施例においては、内部配線により短絡することで、端子間が電気的に接続されている。他の形態として、電流制限用の抵抗や、過電流保護用のヒューズなどが例示できるが、あまり抵抗値が高いものは通電時の発熱が問題となり、また器具自体の消費電力が大きくなってしまうため好ましくない。器具1の既設ソケットや接続された配線、及びLED蛍光灯2の回路保護の観点からは、過電流保護用ヒューズが好ましい。また過電流保護用ヒューズの容量としては、7A以下が望ましい。
Next, the LED lighting tube 3 will be described.
The LED lighting tube 3 is different from the conventional glow tube 30 in that the terminals are electrically connected (conductive). In this embodiment, the terminals are electrically connected by short-circuiting with the internal wiring. Examples of other forms include current limiting resistors and overcurrent protection fuses. However, if the resistance value is too high, heat generation during energization becomes a problem, and the power consumption of the appliance itself increases. Therefore, it is not preferable. From the viewpoint of circuit protection of the existing socket and connected wiring of the appliance 1 and the LED fluorescent lamp 2, a fuse for overcurrent protection is preferable. The capacity of the overcurrent protection fuse is preferably 7 A or less.

以上の構成としたことで、交換作業時の感電のリスクが飛躍的に低減する。以下、交換作業の例をふまえ、その作用について説明する。なおグロー管30は既にLED用点灯管3と交換しているものとする。   With the above configuration, the risk of electric shock during replacement work is drastically reduced. Hereinafter, the operation will be described based on an example of replacement work. It is assumed that the glow tube 30 has already been replaced with the LED lighting tube 3.

器具1に給電側口金21aのみを装着している場合、短絡部27が点灯回路25、LED26と電気的に絶縁されているため、短絡側口金21bにまで電圧が印加されない。このとき電圧が印加されているのは、短絡側口金21bが接続される器具1側の端子(既設ソケット)であり、LED蛍光灯2を保持しているだけでは感電しない。さらには、器具1側の端子が接続されていないため、LED蛍光灯2は点灯しない。   When only the power supply side cap 21a is attached to the appliance 1, the short circuit portion 27 is electrically insulated from the lighting circuit 25 and the LED 26, and thus no voltage is applied to the short circuit side cap 21b. At this time, the voltage is applied to the terminal (existing socket) on the side of the instrument 1 to which the short-circuit side base 21b is connected, and merely holding the LED fluorescent lamp 2 does not cause an electric shock. Furthermore, since the terminal on the appliance 1 side is not connected, the LED fluorescent lamp 2 is not lit.

次に、器具1に短絡側口金21bのみが装着されている場合、上述のよう互いの口金間が絶縁されているため、給電側口金21aに電圧が印加されない。このため感電の恐れがない他、LED蛍光灯2は点灯しない。   Next, when only the short-circuit side base 21b is attached to the instrument 1, since the mutual bases are insulated as described above, no voltage is applied to the power supply side base 21a. For this reason, there is no fear of electric shock, and the LED fluorescent lamp 2 is not lit.

以上のよう本構成によれば、交換作業時に感電するリスクが飛躍的に低下する。また該作業時に、グロー管30およびLED用点灯管3を外しておけば、感電のリスクはより一層低下する。   As described above, according to the present configuration, the risk of electric shock during replacement work is drastically reduced. If the glow tube 30 and the LED lighting tube 3 are removed during the operation, the risk of electric shock is further reduced.

また、本実施例では器具1側の改造を行わない場合を例示したが、LED蛍光灯2の取付器具として最適化すべく、器具1を本発明の作用効果が得られる程度に改造しても良いことは当業者であれば明白である。
例えば、安定器40を外してこの間を短絡、または安定器40を外さずに並列に短絡させても良い。この場合においても上述の感電に対するリスクを低下でき、安定器40による消費電力をも低減させることが可能となる。
Moreover, although the case where the modification by the side of the instrument 1 is not performed is illustrated in the present embodiment, the instrument 1 may be modified to the extent that the effects of the present invention can be obtained in order to optimize the LED fluorescent lamp 2 as an attachment instrument. This will be apparent to those skilled in the art.
For example, the ballast 40 may be removed and short-circuited between them, or the ballast 40 may be short-circuited in parallel without removing the ballast 40. Even in this case, the risk of the above-mentioned electric shock can be reduced, and the power consumption by the ballast 40 can be reduced.

本発明は、両端に口金を備える直管型蛍光灯の他、両口金が一体化された4端子型の口金(端子)を備える丸型(環状)蛍光灯などの交換可能な蛍光灯と、交換可能なグロー管と、をそれぞれ備えるグロースタータ方式の蛍光灯器具全てに適用できる。   The present invention includes exchangeable fluorescent lamps such as a round (annular) fluorescent lamp having a four-terminal base (terminal) in which both bases are integrated, in addition to a straight tube fluorescent lamp having a base at both ends, The present invention can be applied to all glow starter fluorescent lamp fixtures each having a replaceable glow tube.
