Description

本発明は電球形蛍光ランプ及びコンパクト形蛍光ランプに関する。   The present invention relates to a bulb-type fluorescent lamp and a compact fluorescent lamp.

従来の電球形蛍光ランプは、樹脂製のカバーと、口金と、発光管と、発光管の駆動用回路と、発光管と前記駆動回路を固定する樹脂製のホルダー等が備えられたものとなっている。これらの構成要素のうち、発光管は複数の略Ｕ字形状のガラスバルブが複数の連通管部により接続され、デルタ形状やスクウェア形状に配置されている。   A conventional bulb-type fluorescent lamp is provided with a resin cover, a base, an arc tube, a drive circuit for the arc tube, a resin holder for fixing the arc tube and the drive circuit, and the like. ing. Among these components, the arc tube has a plurality of substantially U-shaped glass bulbs connected by a plurality of communication tube portions, and is arranged in a delta shape or a square shape.

このような従来の電球形蛍光ランプは、白熱電球に代わる省エネルギ光源として高効率で長寿命を目的とし、また、白熱電球用器具に広範囲に適合させるために、白熱電球の形状へ近づけるようコンパクト化が進んでいる。   These conventional bulb-type fluorescent lamps aim at high efficiency and long life as an energy-saving light source instead of incandescent bulbs, and are compact enough to approximate the shape of incandescent bulbs in order to adapt to a wide range of incandescent bulb fixtures. Is progressing.

以上のように、従来の電球形蛍光ランプでは、コンパクトにすると発光面積が狭くなり発光効率が低下する。従って、コンパクトな形状でさらなる高効率を追求するためには、従来サイズを維持しつつ、発光管の発光面積を増やすために放電長を増やす必要がある。   As described above, in the conventional light bulb-type fluorescent lamp, when it is made compact, the light emission area is narrowed and the light emission efficiency is lowered. Therefore, in order to pursue higher efficiency with a compact shape, it is necessary to increase the discharge length in order to increase the light emitting area of the arc tube while maintaining the conventional size.

また、従来の電球形蛍光ランプ、特にグローブレスタイプでは、ベースアップ点灯させたときの直下方向の明るさに起因する発光面積が少ないという課題があった。   Further, the conventional bulb-type fluorescent lamp, particularly the globeless type, has a problem that the light emitting area is small due to the brightness directly below when the base is turned on.

本発明の目的は上述した課題を解決するためになされたもので、従来サイズを維持しつつ、発光管の発光面積を増やすために放電長を増し、かつベースアップ点灯させたときの直下方向の明るさに起因する発光面積を増やすことができる蛍光ランプを提供することにある。   The object of the present invention is to solve the above-mentioned problems, and while maintaining the conventional size, the discharge length is increased to increase the light emitting area of the arc tube, and the direction of the direct downward direction when the base is turned on is increased. An object of the present invention is to provide a fluorescent lamp capable of increasing a light emitting area due to brightness.

上記目的を達成するために本発明においては、（１）発光管が１つの略Ｕ字形状ガラスバルブ又は複数の連通した略Ｕ字形状ガラスバルブから構成されている蛍光ランプであって、前記略Ｕ字形状ガラスバルブが前記略Ｕ字形状ガラスバルブの２つの直管部の中心軸に並列した略Ｕ字形状の縦中心線を軸としてねじれ部が形成されていることで達成される。   In order to achieve the above object, the present invention provides (1) a fluorescent lamp in which the arc tube is composed of one substantially U-shaped glass bulb or a plurality of communicating substantially U-shaped glass bulbs. The U-shaped glass bulb is achieved by forming a twisted portion around a substantially U-shaped vertical center line parallel to the central axis of the two straight tube portions of the substantially U-shaped glass bulb.

（２）発光管が１つの略Ｕ字形状ガラスバルブ又は複数の連通した略Ｕ字形状ガラスバルブから構成されている蛍光ランプであって、前記略Ｕ字形状ガラスバルブの２つの直管部の中心軸を含む面に対する前記略Ｕ字形状ガラスバルブの２つの直管部の中心軸に並列した略Ｕ字形状の縦中心線を軸とした前記ガラスバルブのねじれ角θが設けられていることで達成される。   (2) A fluorescent lamp in which the arc tube is composed of one substantially U-shaped glass bulb or a plurality of communicating substantially U-shaped glass bulbs, and the two straight tube portions of the substantially U-shaped glass bulb A twist angle θ of the glass bulb is provided with a substantially U-shaped vertical center line parallel to the central axis of the two straight tube portions of the substantially U-shaped glass bulb with respect to the plane including the central axis. To be achieved.

（３）発光管が１つの略Ｕ字形状ガラスバルブ又は複数の連通した略Ｕ字形状ガラスバルブから構成されている蛍光ランプであって、前記ガラスバルブにねじれ部が一箇所以上形成されていることで達成される。   (3) A fluorescent lamp in which the arc tube is composed of one substantially U-shaped glass bulb or a plurality of communicating substantially U-shaped glass bulbs, and at least one twist portion is formed on the glass bulb. Is achieved.

以上、説明したように、本発明の蛍光ランプによれば、従来サイズを維持しつつ発光管の発光面積を増やすために放電長を従来品より増やすことができ、また、ベースアップ点灯させたときの直下方向の明るさに起因する発光面積を従来品より増やすことができる蛍光ランプが得られる。   As described above, according to the fluorescent lamp of the present invention, the discharge length can be increased from the conventional product in order to increase the light emitting area of the arc tube while maintaining the conventional size, and when the base lamp is turned on. As a result, a fluorescent lamp can be obtained in which the light emitting area due to the brightness in the direction directly below the lamp can be increased as compared with the conventional product.

以下、本発明の一例での実施の形態を図面を参照しつつ説明する。   Hereinafter, an exemplary embodiment of the present invention will be described with reference to the drawings.

図１は、本発明による電球形蛍光ランプの一実施例を示したものである。図示のように、電球形蛍光ランプ１は、樹脂製のカバー２と、口金３と、発光管４と、発光管４の駆動用回路（図示せず）と、発光管４と前記駆動回路（図示せず）を固定する樹脂製のホルダー５等が備えられたものとなっている。これらの構成要素のうち、発光管４は略Ｕ字形状のガラスバルブにねじれ部が形成された複数のガラスバルブ６が複数の連通管部により接続され、デルタ形状（（a）参照）やスクウェア形状（（ｂ）参照）に配置されている。   FIG. 1 shows an embodiment of a bulb-type fluorescent lamp according to the present invention. As shown in the drawing, the bulb-type fluorescent lamp 1 includes a resin cover 2, a base 3, an arc tube 4, a circuit for driving the arc tube 4 (not shown), the arc tube 4 and the drive circuit ( A resin holder 5 or the like for fixing (not shown) is provided. Among these constituent elements, the arc tube 4 is formed by connecting a plurality of glass bulbs 6 each having a twisted portion to a substantially U-shaped glass bulb by a plurality of communicating pipe portions, and forming a delta shape (see (a)) or a square. It is arranged in a shape (see (b)).

ガラスバルブ６に形成されるねじれ部は１箇所以上でも構わない。また、ガラスバルブ６の連通管部に接続される一つ以上のガラスバルブは略Ｕ字形状、直線形状でも構わない。また、複数のガラスバルブ６の配置方法は直列形状、並列形状、格子形状でも構わない。   One or more twisted portions may be formed on the glass bulb 6. Moreover, the one or more glass bulbs connected to the communicating tube portion of the glass bulb 6 may be substantially U-shaped or linear. Further, the arrangement method of the plurality of glass bulbs 6 may be a series shape, a parallel shape, or a lattice shape.

図２（a）は、ガラスバルブ６の要部拡大正面図である。図２（ｂ）は、ガラスバルブ６の要部拡大側面図である。ガラスバルブ６は略Ｕ字形状ガラスバルブが略Ｕ字形状ガラスバルブの２つの直管部の中心軸に並列したＵ字形状の縦中心線を軸として９０度のねじれ部を形成したものを示したものである。   FIG. 2A is an enlarged front view of the main part of the glass bulb 6. FIG. 2B is an enlarged side view of the main part of the glass bulb 6. Glass bulb 6 shows a substantially U-shaped glass bulb formed with a twisted portion of 90 degrees about a U-shaped vertical center line in parallel with the central axis of two straight tube portions of the substantially U-shaped glass bulb. It is a thing.

さて、その電球形蛍光ランプ１での本発明によるガラスバルブの特徴について説明すれば、以下のようである。   Now, the characteristics of the glass bulb according to the present invention in the bulb-type fluorescent lamp 1 will be described as follows.

即ち、略Ｕ字形状ガラスバルブが略Ｕ字形状ガラスバルブの２つの直管部の中心軸に並列した略Ｕ字形状の縦中心線を軸として９０度のねじれ部を形成しデルタ形状やスクウェア形状に配置されていることで、従来品の全長を維持しつつ発光管の発光面積を増やすために放電長を従来品より増やすことができ、また、ベースアップ点灯させたときの直下方向の明るさに起因する発光面積を従来品より増やすことができる。   That is, a substantially U-shaped glass bulb forms a 90-degree twisted portion around a substantially U-shaped vertical center line parallel to the central axis of the two straight tube portions of the substantially U-shaped glass bulb to form a delta shape or square By arranging in the shape, the discharge length can be increased to increase the light emitting area of the arc tube while maintaining the total length of the conventional product, and the brightness in the downward direction when the base is lit up The light emission area resulting from the height can be increased as compared with the conventional product.

ねじれ角θは９０度のときに、ベースアップ点灯させたときの直下方向の明るさに起因する発光面積が最大になるが、ねじれ角θが微小であっても構わないし、極大であっても構わない。   When the twist angle θ is 90 degrees, the light emitting area due to the brightness in the direct downward direction when the base is turned on is maximized. However, the twist angle θ may be small or maximum. I do not care.

図３は、本発明品による発光管の放電長の従来品との割合の比較と、ベースアップ点灯させたときの直下方向の明るさに起因する発光面積の従来品との割合の比較を示したものである。本発明品では、例えばガラスバルブ６がデルタ形状に配置された蛍光ランプは、発光管の放電長が従来品の３０３ｍｍに対し、３１８ｍｍとなり、１０５％まで増える。また、本発明品では、例えばガラスバルブ６がデルタ形状に配置された蛍光ランプは、ベースアップ点灯させたときの直下方向の明るさに起因する発光面積が従来品の（１７８×１０-６）ｍ２に対し、（２８５×１０-６）ｍ２となり、１６０％まで増える。 FIG. 3 shows a comparison of the ratio of the discharge length of the arc tube according to the present invention with that of the conventional product, and a comparison of the ratio of the light emitting area due to the brightness in the direct lower direction when the base is turned on. It is a thing. In the product of the present invention, for example, in a fluorescent lamp in which the glass bulbs 6 are arranged in a delta shape, the discharge length of the arc tube is 318 mm as compared with 303 mm of the conventional product, increasing to 105%. In addition, in the product of the present invention, for example, a fluorescent lamp in which the glass bulb 6 is arranged in a delta shape has a light emitting area due to the brightness in the direct downward direction when the base is turned on (178 × 10 −6 ). For m 2 , it is (285 × 10 −6 ) m 2 , increasing to 160%.

本発明の適用はコンパクト形蛍光ランプでも構わない。   The application of the present invention may be a compact fluorescent lamp.
