Description

【考案の詳細な説明】[Detailed description of the invention]
【0001】[0001]
【考案の属する技術分野】[Technical field to which the invention belongs]
本考案は、LEDランプ又はLEDチップを光源として用いたLED電球に関 する。 The present invention relates to an LED bulb using an LED lamp or an LED chip as a light source.
【0002】[0002]
【従来の技術】[Prior art]
一般に、フィラメントを光源として備えた白熱電球は、発生する熱量及び消費 電力が大きく、また寿命が短い。これらの問題を解決するために、発生熱量及び 消費電力が小さく、寿命の長いLEDランプをフィラメントの代わりに電球の光 源として用いることが考えられている。 In general, an incandescent lamp having a filament as a light source generates a large amount of heat and consumes a large amount of power and has a short life. In order to solve these problems, it has been considered to use a long-life LED lamp as a light source for a light bulb instead of a filament because the generated heat and power consumption are small.
【0003】[0003]
【考案が解決しようとする課題】[Problems to be solved by the invention]
しかし、LEDランプは、単体では光量が小さくそのままでは電球の光源とし て使用することができない。そこでプリント配線基板上にLEDランプを多数配 設するにより光量を確保することが考えられるが、電球の口金取付部の内径以上 のプリント配線基板を用いることができないため、得られる光量には限界があっ た。また、LEDランプの配設面であるプリント配線基板の配線プリント面側か らしか光を出射できないため、光が照射される範囲が限定されるという問題も生 じた。 However, the LED lamp alone has a small light quantity and cannot be used as a light source of a light bulb as it is. Therefore, it is conceivable to secure a sufficient amount of light by arranging a large number of LED lamps on a printed circuit board. there were. In addition, since light can be emitted only from the wiring printed surface side of the printed wiring board on which the LED lamps are provided, there is also a problem that the range of light irradiation is limited.
【0004】 そこで本考案は、上記の問題点に鑑み、所望の光量及び照射範囲を得ることが できるLED電球を提供することを課題とする。[0004] In view of the above problems, an object of the present invention is to provide an LED bulb that can obtain a desired light amount and irradiation range.
【0005】[0005]
【課題を解決するための手段】[Means for Solving the Problems]
上記課題を解決するために本考案は、複数個のLEDランプ又はLEDチップ を可撓性部材によって連鎖して成るLED連鎖体を、電球本体を構成する中空体 内に設置したことを特徴とする。 In order to solve the above problems, the present invention is characterized in that an LED chain formed by linking a plurality of LED lamps or LED chips by a flexible member is installed in a hollow body constituting a light bulb main body. .
【0006】 この構成によれば、LED連鎖体の可撓性部材を曲折又は捻転することにより LED連鎖体を自由な形状に設定できるので、多数のLEDランプ又はLEDチ ップを口金取付部を通し中空体内に設置して所望の光量を得ることができる。ま た、LED連鎖体の可撓性部材を曲折又は捻転することにより各LEDランプ又 は各LEDチップを様々な角度に向けることができるので所望の照射範囲を得る ことができる。According to this configuration, the LED chain can be set in a free shape by bending or twisting the flexible member of the LED chain, so that a large number of LED lamps or LED chips can be attached to the base mounting portion. A desired amount of light can be obtained by installing the through-hole in the hollow body. Further, by bending or twisting the flexible member of the LED chain, each LED lamp or each LED chip can be directed at various angles, so that a desired irradiation range can be obtained.
【0007】 また、白熱電球のガラス球からなる中空体、口金及びステムを含む、フィラメ ント以外の部材をそのまま用い、フィラメントの代わりにLED連鎖体をステム に支持させることもできる。これによれば、白熱電球と同一の工程で電球を製造 でき、電球の製造に際し新たな設備投資等のコストがかからない。[0007] Further, a member other than the filament, including a hollow body made of a glass bulb of an incandescent lamp, a base, and a stem can be used as it is, and the LED chain can be supported by the stem instead of the filament. According to this, a bulb can be manufactured in the same process as an incandescent bulb, and no new capital investment costs are required in the manufacture of the bulb.
【0008】 また、本考案では、発光の際に発生する熱量がフィラメントのように大きくな いため、電球本体を構成する中空体を透明又は半透明の樹脂で成形することもで きる。これによれば、中空体の材料選択の幅が広がり、多種多様な形状の電球を 得ることが容易となる。Further, in the present invention, since the amount of heat generated at the time of light emission is not as large as that of a filament, the hollow body constituting the light bulb main body can be formed of a transparent or translucent resin. According to this, the range of choice of materials for the hollow body is expanded, and it becomes easy to obtain light bulbs of various shapes.
【0009】[0009]
【考案の実施の形態】[Embodiment of the invention]
図1を参照して、1は一般的な白熱電球に用いられる電球本体であり、中空体 たるガラス球1aと口金1bとステム1cとを備えている。ここで、白熱電球で は、ステム1cにフィラメントを支持させているが、このものでは、ステム1c にフィラメントに代えてLED連鎖体2を支持させ、ステム1cからガラス球1 a内に延出している2本の内部導入線1d、1dにLED連鎖体2の両端をそれ ぞれ接続している。LED連鎖体2は、図2に示すように、LEDチップを透明 体に埋設して成るLEDランプ3の複数個を、薄い金属板(例えば0.1mmの 銅板)から成る可撓性部材4により直列接続で連鎖させて構成されている。図1 を参照して、該LED連鎖体2は、板材からなる可撓性部材4を捻転することに より隣合うLEDランプ3の配光を少しずつずらしてあり、また、可撓性部材4 の2箇所を曲折することにより、LED連鎖体2全体が逆U字状に加工されてい る。ガラス球1a内のステム1c上にはハブ1eが設けられ、該ハブ1eから2 本のアンカ1f、1fがガラス球1a内に延出している。該アンカ1f、1fは 、上記LED連鎖体2の2箇所の曲折部分をそれぞれ支持している。 Referring to FIG. 1, reference numeral 1 denotes a light bulb main body used for a general incandescent light bulb, which includes a hollow glass bulb 1a, a base 1b, and a stem 1c. Here, in the incandescent lamp, the stem 1c supports a filament, but in this case, the stem 1c supports the LED chain 2 instead of the filament, and extends from the stem 1c into the glass bulb 1a. The two ends of the LED chain 2 are connected to two internal introduction lines 1d and 1d, respectively. As shown in FIG. 2, the LED chain 2 includes a plurality of LED lamps 3 each having an LED chip embedded in a transparent body and a flexible member 4 formed of a thin metal plate (for example, a 0.1 mm copper plate). It is configured by chaining in series. Referring to FIG. 1, the LED chain 2 is configured such that the light distribution of adjacent LED lamps 3 is slightly shifted by twisting a flexible member 4 made of a plate material. By bending these two locations, the entire LED chain 2 is processed into an inverted U-shape. A hub 1e is provided on the stem 1c in the glass bulb 1a, and two anchors 1f and 1f extend from the hub 1e into the glass bulb 1a. The anchors 1f, 1f respectively support two bent portions of the LED chain 2.
【0010】 尚、上記LED連鎖体2では、LEDランプ連鎖してLED連鎖体2を構成し たが、LEDランプの代わりにLEDチップを用いて直接可撓性部材によって連 鎖させてLED連鎖体を構成することも可能である。[0010] In the above-described LED chain 2, the LED chain 2 is formed by linking the LED lamps. However, instead of the LED lamp, the LED chain is directly linked by a flexible member using an LED chip. Can also be configured.
【0011】 尚、図3に示すように、上記実施の形態の逆U字状のLED連鎖体2に代えて 、板材からなる可撓性部材2を曲折及び捻転することにより、LEDランプ3の 配光面が外側に向くように全体を螺旋状に加工したLED連鎖体2をステム1c に支持させてもよい。As shown in FIG. 3, instead of the inverted U-shaped LED chain 2 of the above-described embodiment, the flexible member 2 made of a plate material is bent and twisted to thereby form the LED lamp 3. The LED chain 2 entirely processed into a spiral so that the light distribution surface faces outward may be supported by the stem 1c.
【0012】 尚、上記実施の形態においては、ガラス球1aを備えた電球本体1を用いたL ED電球について説明したが、該ガラス球1aの代わりに、透明又は半透明な樹 脂(例えば、ポリカーボネードやアクリルやポリ塩化ビフェニール)を射出成形 や押出し成形等して形成したものを中空体として用いてもよい。この場合、成形 時に拡散材や蛍光材等を成形材料に混入することも可能である。In the above embodiment, the LED bulb using the bulb main body 1 having the glass bulb 1a has been described. However, instead of the glass bulb 1a, a transparent or translucent resin (for example, A material formed by injection molding, extrusion molding, or the like of polycarbonate, acrylic, or polychlorinated biphenyl) may be used as the hollow body. In this case, it is possible to mix a diffusing material, a fluorescent material, and the like into the molding material during molding.
【0013】[0013]
【考案の効果】[Effect of the invention]
以上の説明から明らかなように、本考案は、中空体内に多数のLEDランプ、 又はLEDチップを設置することができるので所望の光量を得ることができ、ま た、各LEDランプ又は各LEDチップを様々な角度に向けることができるので 、所望の照射範囲を得ることがきでる。また、白熱電球の中空体及び口金及びス テム等の部材をそのまま用いることで、白熱電球と同一の工程で電球を製造でき るので、電球の製造に際し新たな設備投資等のコストがかからない。また、中空 体の材料としてガラスの代わりに透明又は半透明の樹脂を用いることができるの で、中空体の材料選択の幅が広がり、多種多様な形状の電球を得ることが容易と なる。 As is clear from the above description, the present invention can provide a desired amount of light because a large number of LED lamps or LED chips can be installed in the hollow body, and each LED lamp or each LED chip can be obtained. Can be directed to various angles, so that a desired irradiation range can be obtained. In addition, by using the hollow body of the incandescent lamp, and the members such as the base and the stem, as they are, the bulb can be manufactured in the same process as the incandescent lamp. In addition, since a transparent or translucent resin can be used instead of glass as the material of the hollow body, the choice of the material of the hollow body is widened, and it becomes easy to obtain light bulbs of various shapes.
