Description

【０００１】
【発明の属する技術分野】
本発明は、環形蛍光ランプに関するものである。
【０００２】
【従来の技術】
従来、実公昭６０−４２４４０号公報に開示された環形蛍光ランプは、図６および図７に示すように、環形のバルブ（図示せず）と、バルブの両端部を包囲連結するように取り付けられた樹脂製の口金１４とを備えている。
【０００３】
この口金１４は、二分割された半円筒形の口金構成部材１５，１６（第一部材および第二部材）から構成されている。口金構成部材１５，１６には、嵌合のための係止凸部１７（係止部）と係止凹部１８（被係止部）とがそれぞれ設けられている。この口金構成部材１５，１６には、ランプ寿命中、係止凸部１７と係止凹部１８との係止部分（以下、単に「係止部分」という）が口金１４の材料である樹脂の熱変形によって外れないようにするため、その内周面に沿った補強用リブ１９が複数個設けられている。
【０００４】
なお、ランプ電力３０Ｗ、３２Ｗおよび４０Ｗの環形蛍光ランプに使用されている口金１４の外形寸法は、一般的に、外径φが３０．２ｍｍ、外周長Ｌoが５１．０ｍｍ、内周長Ｌiが４１．０ｍｍである。また、上記したようにランプ寿命中、係止部分が樹脂の熱変形によって外れないようにするため、口金構成部材１５，１６の肉厚は例えば１．２ｍｍ、補強用リブ１９の高さは例えば４ｍｍ〜７ｍｍ、その厚さは１．２ｍｍにそれぞれ設定する必要があった。
【０００５】
そして、この口金１個当たりの樹脂の使用量は、一般的に使用されているポリブチレンテレフタレート（ＰＢＴ）を用いた場合、約１２ｇであった。
【０００６】
【発明が解決しようとする課題】
このように従来の環形蛍光ランプでは、ランプ寿命中、係止部分が口金１４の材料である樹脂の熱変形によって外れないようにするため、十分に厚みのある大きな補強用リブ１９を複数個設けなければならず、したがってその樹脂の使用量が多くなり、材料費が高くなるという問題があった。
【０００７】
本発明は、このような問題を解決するためになされたもので、従来の環形蛍光ランプに比して口金の材料である樹脂の使用量を削減することができ、しかもランプ寿命中、係止部分がその樹脂の熱変形によって外れるのを確実に防止することができる低コストな環形蛍光ランプを提供することを目的とする。
【０００８】
【課題を解決するための手段】
本発明の環形蛍光ランプは、環形のバルブと、互いに組み合わされて前記バルブの両端部を包囲連結するための第一部材および第二部材を有する樹脂製の口金とを備え、前記第一部材には前記第二部材に設けられた被係止部に係止される係止部が設けられ、かつ前記第二部材には前記係止部が前記被係止部に係止されている状態において前記係止部の位置を規制するための規制部材が設けられるとともに前記第二部材の外面にはリード線を介して電極に接続されている４本の金属ピンが設けられ、前記規制部材は、弾性変形可能な板状に形成され、前記第一部材の前記係止部間および前記第二部材の前記規制部材と前記金属ピン取り付け部との間のうち少なくとも一方には、補強用リブが設けられていることを特徴とする。
【０００９】
この構成によれば、点灯中、口金の材料である樹脂が熱変形して、係止部が被係止部から外れようとしても、規制部材によって係止部が被係止部から外れるのを防止することができ、係止部と被係止部との係止状態を確実に維持することができる。つまり、従来の環形蛍光ランプに比して、ランプ寿命中、係止部と被係止部との係止部分が口金の材料である樹脂の熱変形によって外れるのを一層防止することができる。しかも、大きな補強用リブを有する従来の環形蛍光ランプとは異なり、規制部材を設けるために必要な樹脂の使用量はわずかなので、コスト増を抑えることができる。
【００１０】
また、第一部材および第二部材のうち少なくとも一方に補強用リブが設けられているので、規制部材によって係止部と被係止部との係止状態を確実に維持することができる結果、補強用リブを肉薄化したり、補強用リブの大きさを縮小化したりすることができるので、口金の材料である樹脂の使用量を大幅に削減することができる。よって、ランプ寿命中、係止部と被係止部との係止部分が口金の材料である樹脂の熱変形によって外れるのを確実に防止することができ、しかも低コストな環形光ランプを実現することができる。
【００１１】
なお、樹脂が熱変形するのは主に点灯中であるが、係止部分が外れるのは点灯中だけでなく、その熱変形によって外れやすい状態にあり、そこに外部からの衝撃等が加わって消灯中にでも外れる場合が起こり得る。
【００１２】
また、本発明の環形蛍光ランプは、前記規制部材が前記係止部を前記被係止部側へ押圧している構成を有している。
【００１３】
この構成によれば、係止部が規制部材によって被係止部側へ押圧されているので、口金の材料である樹脂が熱変形しても、係止部が被係止部から外れるのを一層防止することができ、係止部と被係止部との係止状態を一層確実に維持することができる。
【００１４】
【発明の実施の形態】
本発明の実施の形態である環形蛍光ランプは、図２に示すように、環形のガラス製のバルブ１と、このバルブ１の両端部を包囲し、かつ連結するように取り付けられたＰＢＴやポリカーボネイト（ＰＣ）等からなる樹脂製の口金２とを備えている。
【００１５】
バルブ１内の両端部には、電極（図示せず）が設けられている。また、バルブ１内には、水銀や希ガス等の封入物が所定量封入されている。さらに、バルブ１の内面には、蛍光体膜（図示せず）が形成されている。
【００１６】
口金２は、図５に示すように、バルブ１の環外径側の外周長Ｌoがバルブ１の環内径側の内周長Ｌiに比して長い略円筒形を有しており、図３に示すように、二分割された略半円筒形の一対の第一部材３と第二部材４とから構成されている。
【００１７】
なお、本実施の形態では、ランプ電力３０Ｗ、３２Ｗおよび４０Ｗの環形蛍光ランプに使用される口金２を例示している。したがって、口金２の外形寸法は、外径φが３０．２ｍｍ、外周長Ｌoが５１．０ｍｍ、内周長Ｌiが４１．０ｍｍである。
【００１８】
図１および図４に示すように、第一部材３の両側端部３ａの中央付近には、第二部材４（図４には図示せず）側に向かってまっすぐ延びる幅５．０ｍｍ、厚さ１．０ｍｍの板状の係止体５と、この係止体５の先端部に形成されており、係止体５の長手方向に対して垂直方向で、かつ口金２の外部へ向かって０．５ｍｍ程度突出した凸状の係止部６とが設けられている。また、第一部材３の係止部６間には、第一部材３の内周面に沿った高さ１ｍｍ〜４ｍｍ、厚さ０．８ｍｍの板状の補強用リブ７が設けられている。
【００１９】
一方、図１および図５に示すように、第二部材４の両側端部４ａの中央付近には、第一部材３の係止部６が係止される凹状の被係止部８と、この被係止部８より内側に第一部材３（図５には図示せず）側に向かってまっすぐ延びる板状の規制部材９とが設けられている。また、第二部材４の規制部材９と後述の金属ピン取り付け部１０との間には、第二部材４の内周面に沿った高さ１ｍｍ〜４ｍｍ、厚さ０．８ｍｍの板状の補強用リブ１１が設けられている。さらに、第二部材４の両端部には、第二部材４の内周面に沿った板状の補強用リブ１２が設けられている。
【００２０】
また、第二部材４の外面には、リード線（図示せず）を介して電極に接続されている４本の金属ピン１３が設けられている。この金属ピン１３は、第二部材４の内面に形成されている金属ピン取り付け部１０に挿入され、固定されている。
【００２１】
図１に示すように、第一部材３と第二部材４とが組み合わされる際、第一部材３の係止部６は、規制部材９を押し広げるように弾性変形させながら第二部材４の被係止部８に係止される。そして、係止部６が被係止部８に係止された後、係止部６は規制部材９の元の形に戻ろうとする力によって被係止部８側（図１中、矢印Ｚの方向）へ押圧される。もちろん、係止体５自体も第一部材３と第二部材４とが組み合わされる際は弾性変形する。
【００２２】
次に、このような本発明の実施の形態にかかる環形蛍光ランプ（以下、「本発明品」という）を１０個作製し、作製した各々の環形蛍光ランプを点灯させ、定格寿命（６０００時間）中に口金２の係止部６と被係止部８との係止部分が外れるかどうかを確認した。
【００２３】
その結果、本発明品では、定格寿命中、係止部６が被係止部８から外れたものは全くなかった。
【００２４】
また、本発明品の口金２に使用されている樹脂（ＰＢＴ）の使用量は９ｇであった。このように本発明品では、図６および図７に示すような従来の環形蛍光ランプの口金に使用されている樹脂の使用量１２ｇに比して約２５％削減することができた。
【００２５】
以上のように本発明の実施の形態にかかる環形蛍光ランプの構成によれば、点灯中、口金２の材料である樹脂が熱変形して、係止部６が被係止部８から外れようとしても、規制部材９によって係止部６を被係止部８から外れるのを防止することができ、係止部６と被係止部８との係止状態を確実に維持することができる。つまり、従来の環形蛍光ランプに比して、ランプ寿命中、係止部６と被係止部８との係止部分が口金２の材料である樹脂の熱変形によって外れるのを一層防止することができる。しかも、大きな補強用リブを有する従来の環形蛍光ランプとは異なり、規制部材９を設けるために必要な樹脂の使用量はわずかなので、コスト増を抑えることができる。特に、規制部材９によって係止部６と被係止部８との係止状態を確実に維持することができる結果、補強用リブ７，１１，１２を肉薄化したり、補強用リブ７，１１，１２の大きさを縮小化したりすることができるので、口金２の材料である樹脂の使用量を大幅に削減することができる。よって、低コストな環形蛍光ランプを実現することができる。さらに、特に、係止部６は規制部材９によって被係止部８側へ押圧されているので、係止部６と被係止部８との係止状態を一層確実に維持することができる。
【００２６】
なお、上記実施の形態では、第一部材３および第二部材４は一つの部材から構成されている場合について説明したが、第一部材３および第二部材４は複数の部材から構成されても上記と同様の効果を得ることができる。
【００２７】
また、上記実施の形態では、規制部材９は係止部６を被係止部８側へ押圧している場合について説明したが、規制部材９は係止部６に接触またはわずかな隙間をあけて近接している場合でも上記と同様の効果を得ることができる。
【００２８】
【発明の効果】
以上説明したように本発明は、従来の環形蛍光ランプに比して口金の材料である樹脂の使用量を削減することができ、しかもランプ寿命中、係止部分がその樹脂の熱変形によって外れるのを確実に防止することができる低コストな環形蛍光ランプを提供することができるものである。

BACKGROUND OF THE INVENTION
The present invention relates to an annular fluorescent lamp.
[0002]
[Prior art]
Conventionally, as shown in FIGS. 6 and 7, the annular fluorescent lamp disclosed in Japanese Utility Model Publication No. 60-42440 is attached so as to surround and connect an annular bulb (not shown) and both ends of the bulb. And a resin base 14.
[0003]
The base 14 is composed of two half-cylindrical base constituent members 15 and 16 (first member and second member). The base component members 15 and 16 are each provided with a locking projection 17 (locking portion) and a locking recess 18 (locked portion) for fitting. The base component members 15 and 16 are provided with heat of resin, which is a material of the base 14, in which a locking portion between the locking projection 17 and the locking recess 18 (hereinafter simply referred to as a “locking portion”) during the lamp life. A plurality of reinforcing ribs 19 are provided along the inner peripheral surface so as not to come off due to deformation.
[0004]
Incidentally, the lamp power 30 W, external dimensions of the base 14 used in the circular fluorescent lamp of 32W and 40W are generally outside diameter φ is 30.2 mm, the outer peripheral length L o is 51.0Mm, inner peripheral length L i is 41.0 mm. Further, as described above, the thickness of the base component members 15 and 16 is 1.2 mm, for example, and the height of the reinforcing rib 19 is It was necessary to set each of 4 mm to 7 mm and the thickness to 1.2 mm.
[0005]
And the usage-amount of resin per this nozzle | cap | die was about 12g when the polybutylene terephthalate (PBT) generally used is used.
[0006]
[Problems to be solved by the invention]
As described above, in the conventional annular fluorescent lamp, a plurality of sufficiently large reinforcing ribs 19 are provided in order to prevent the locking portion from being removed by thermal deformation of the resin that is the material of the base 14 during the lamp life. Therefore, there is a problem that the amount of the resin used is increased and the material cost is increased.
[0007]
The present invention has been made to solve such problems, and can reduce the amount of resin used as a base material as compared with a conventional annular fluorescent lamp. An object of the present invention is to provide a low-cost ring-shaped fluorescent lamp that can reliably prevent the portion from being detached due to thermal deformation of the resin.
[0008]
[Means for Solving the Problems]
An annular fluorescent lamp of the present invention includes an annular bulb and a resin base having a first member and a second member that are combined with each other to surround and connect both end portions of the bulb, and the first member includes Is provided with a locking portion that is locked to the locked portion provided in the second member, and the second member is locked in the locked portion with the locked portion. A restricting member for restricting the position of the locking portion is provided, and four metal pins connected to the electrodes via lead wires are provided on the outer surface of the second member . Reinforcing ribs are formed between the locking portions of the first member and between the restricting member and the metal pin mounting portion of the second member. It is characterized in that is.
[0009]
According to this configuration, even when the resin that is the material of the base is thermally deformed during lighting and the locking portion is about to come off from the locked portion, the locking portion is released from the locked portion by the restricting member. Therefore, the locked state between the locking portion and the locked portion can be reliably maintained. That is, as compared with the conventional annular fluorescent lamp, it is possible to further prevent the locking portion between the locking portion and the locked portion from coming off due to thermal deformation of the resin that is the material of the base during the lamp life. In addition, unlike conventional annular fluorescent lamps having large reinforcing ribs, the amount of resin required for providing the regulating member is small, and therefore an increase in cost can be suppressed.
[0010]
Further, since the reinforcing rib on at least one of the first member and the second member is provided, it is possible to reliably maintain the locking state between the locking portion and the locked portion by restricting member results, Since the reinforcing rib can be thinned or the size of the reinforcing rib can be reduced, the amount of resin used as the base material can be greatly reduced. Therefore, it is possible to reliably prevent the locking part between the locking part and the locked part from coming off due to thermal deformation of the resin that is the base material during the lamp life, and to realize a low-cost annular light lamp. can do.
[0011]
The resin is thermally deformed mainly during lighting, but it is not only during lighting that the locking part is released, but it is in a state where it is easily removed due to its thermal deformation. It may happen that the light comes off even when it is turned off.
[0012]
The annular fluorescent lamp of the present invention has a configuration in which the restricting member presses the locking portion toward the locked portion.
[0013]
According to this configuration, since the locking portion is pressed toward the locked portion by the restricting member, the locking portion can be removed from the locked portion even if the resin that is the material of the base is thermally deformed. This can be further prevented, and the locking state between the locking portion and the locked portion can be more reliably maintained.
[0014]
