That are lighting circuit components such as lead components such as electrolytic capacitors and chip components such as transistors are mounted on the mounting surface. In addition, four wrapping pins 7c1, 7c2, 7c3, and 7c4 are projected in a straight line on the side opposite to the base 2 side, that is, on the arc tube 4 side so as to be equally spaced.

次に図3および図4に発光管4と回路基板7cとの位置関係の具体的構成を示す。回路基板7に実装された4本のラッピングピン7c1〜7c4は基板表面に配設され、ランプ長手方向からみたとき、一対のバルブ端部4a、4bの略中心部である圧潰封止された細管4cを結ぶ仮想線aと回路基板7とは略直交関係にある。さらに、一対のリード線4d1〜4d4を結んだ仮想線bはそれぞれが平行関係を保つよう一対のバルブ端部4a、4bに圧潰封着され、ラッピングピン7c1〜7c4に接続されている。   Next, FIGS. 3 and 4 show a specific configuration of the positional relationship between the arc tube 4 and the circuit board 7c. Four wrapping pins 7c1 to 7c4 mounted on the circuit board 7 are arranged on the surface of the board, and when viewed from the longitudinal direction of the lamp, they are crush-sealed tubules that are substantially center portions of the pair of bulb end portions 4a and 4b. The virtual line a connecting 4c and the circuit board 7 are in a substantially orthogonal relationship. Further, the imaginary line b connecting the pair of lead wires 4d1 to 4d4 is crushed and sealed to the pair of valve end portions 4a and 4b so as to keep the parallel relationship, and is connected to the wrapping pins 7c1 to 7c4.

図3のように、ホルダ5に取付けられた発光管4から引き出された一対のリード線4d1、4d2および4d3、4d4を結んだ仮想線bが平行しているとともに、この仮想線bとバルブ端部中心軸を結んだ仮想線aと直交し、かつ一対のバルブ端部間に平面が仮想線bと直交する回路基板が配置されているので、回路基板7aの両面のどの位置にラッピングピンが配設されている場合においても、各電極の4本のリード線4dを配線する場合に所定間隔を保ちやすくなり、ラッピングピン7cに容易に接続することができる。さらに、一対のバルブ端部4a,4b側面を加熱し、圧潰封止する作業においても、バルブ直状部4f間に加熱用バーナーを位置することで、一対のバルブ端部4a,4bを同時に加熱することができ、製造コストが削減できる。また、加熱後、バルブ端部4a,4b間の加熱用バーナーを圧潰封止装置の一方を挿入することで、圧潰方向を確実規制することができるため、製造作業が容易となる。   As shown in FIG. 3, an imaginary line b connecting a pair of lead wires 4d1, 4d2 and 4d3, 4d4 drawn from the arc tube 4 attached to the holder 5 is parallel, and the imaginary line b and the bulb end are connected. Since a circuit board that is orthogonal to the imaginary line a connecting the central axes of the parts and the plane is orthogonal to the imaginary line b between the pair of valve ends, the wrapping pin is located at any position on both sides of the circuit board 7a Even when the four lead wires 4d of each electrode are arranged, it is easy to maintain a predetermined interval, and it is possible to easily connect to the wrapping pin 7c. Furthermore, even in the operation of heating and crushing and sealing the side surfaces of the pair of valve end portions 4a and 4b, the pair of valve end portions 4a and 4b are simultaneously heated by positioning the heating burner between the valve straight portions 4f. Manufacturing costs can be reduced. In addition, after the heating, by inserting one of the crushing and sealing devices into the heating burner between the valve end portions 4a and 4b, the crushing direction can be reliably regulated, so that the manufacturing work is facilitated.

図4の圧潰封止方向は圧潰封止面がラッピングピン7cへ対向する様に、仮想線aに対して約45℃傾斜している。このように圧潰封止部は、一対の直状部の両側面から加熱するとともに圧潰封止するため、直状部4f間に封止装置を挿入することがないため、封止装置を比較的狭い空間である直状部4f間を移動することがないので、封止装置がバルブに接触し、バルブ破損ことがないので、封止工程の作業を容易にすることができる。さらに、ラッピングピン7c1〜7c4にリード線4dをラッピング接続する工程において、バルブ端部4a、4bに封着された一対のリード線4d1〜4d4は、ラッピングピンに対向するように圧潰封止されているため、互いの接触を一層抑制することができる。   The crushing sealing direction of FIG. 4 is inclined at about 45 ° C. with respect to the imaginary line a so that the crushing sealing surface faces the wrapping pin 7c. In this way, the crushing sealing portion is heated from both side surfaces of the pair of straight portions and crush-sealed, so that the sealing device is not inserted between the straight portions 4f. Since there is no movement between the straight portions 4f which are a narrow space, the sealing device contacts the valve and the valve is not damaged, so that the work of the sealing process can be facilitated. Further, in the step of wrapping and connecting the lead wire 4d to the wrapping pins 7c1 to 7c4, the pair of lead wires 4d1 to 4d4 sealed to the valve end portions 4a and 4b are crushed and sealed so as to face the wrapping pins. Therefore, mutual contact can be further suppressed.

このように構成された電球形蛍光ランプ1の具体的構成の一例は、次の通りである。すなわち、発光管4の発光管最大外径(螺旋外径)が54mm、発光管4の高さh1が64±1mm、発光管4の最大径部4kの水平中心軸Oaから一対の電極封止端部4a,4bの外面までの高さh2が約40mmである。一対の電極4i,4j同士間の放電路長は360〜610mmであり、ガラスバルブのバルブ径に応じて相違する。例えばガラスバルブの径(バルブ径)が8mmのとき、放電路長が476mm、バルブ径が9mmのとき、放電路長が374mmである。また、口金2の外径が26mmであり、発光管4の直状部4f,4f間の最大幅w1(30.5mm)は、口金2の外径φ3の約1.17倍である。   An example of a specific configuration of the bulb-type fluorescent lamp 1 configured as described above is as follows. That is, the arc tube maximum outer diameter (spiral outer diameter) of the arc tube 4 is 54 mm, the height h 1 of the arc tube 4 is 64 ± 1 mm, and a pair of electrodes are sealed from the horizontal central axis Oa of the maximum diameter portion 4 k of the arc tube 4. The height h2 to the outer surface of the ends 4a, 4b is about 40 mm. The length of the discharge path between the pair of electrodes 4i and 4j is 360 to 610 mm, and differs depending on the bulb diameter of the glass bulb. For example, when the glass bulb diameter (bulb diameter) is 8 mm, the discharge path length is 476 mm, and when the bulb diameter is 9 mm, the discharge path length is 374 mm. Further, the outer diameter of the base 2 is 26 mm, and the maximum width w1 (30.5 mm) between the straight portions 4f and 4f of the arc tube 4 is about 1.17 times the outer diameter φ3 of the base 2.

したがって、この電球形蛍光ランプ1によれば、一般照明用電球近似の外観を得ることができる。   Therefore, according to this bulb-type fluorescent lamp 1, it is possible to obtain an appearance similar to a general lighting bulb.

本実施の形態の電球形蛍光ランプ1によれば、バルブ端部4a,4bに封着されたフィラメント電極4h,4iを継線するリード線4d1〜4d4を結ぶ仮想線bはが略並行するように圧潰封止しているとともに、一対のバルブ端部中心軸を結ぶ仮想線と回路基板7は略直交するように回路基板7aを縦形に配置しているので、発光管4と点灯装置7の接続作業において、リード線4d1〜4d4からラッピングピン7c1〜7c4へ配線した場合にリード線同士が所定の間隔を保ちやすくなる。したがって、リード線4d1〜4d4同士が接触するなどの不具合を容易に抑制することができると共に、接続作用が容易となる。また、バルブ端部4a、4bから引き出されたリード線4d1〜4d4をラッピングピン7c1〜7c4まで誘導する手段や接触抑制手段を有していないものにおいても、容易に配線作業を行えるとともにリード線4d1〜4d4の接触などの不具合を抑制することができる。   According to the bulb-type fluorescent lamp 1 of the present embodiment, the virtual lines b connecting the lead wires 4d1 to 4d4 connecting the filament electrodes 4h and 4i sealed to the bulb ends 4a and 4b are substantially parallel to each other. Since the circuit board 7a is arranged vertically so that the virtual line connecting the central axis of the pair of bulb ends and the circuit board 7 are substantially orthogonal to each other, the arc tube 4 and the lighting device 7 In the connection work, when the lead wires 4d1 to 4d4 are wired to the wrapping pins 7c1 to 7c4, the lead wires can easily maintain a predetermined interval. Therefore, it is possible to easily suppress problems such as contact between the lead wires 4d1 to 4d4 and to facilitate connection. Further, even if the lead wires 4d1 to 4d4 drawn from the valve end portions 4a and 4b are not provided with a means for guiding the lead wires 4d1 to 4d4 to the wrapping pins 7c1 to 7c4 or a contact suppressing means, wiring work can be easily performed and the lead wire 4d1 Problems such as contact of ˜4d4 can be suppressed.

図5は本発明の照明装置11の概略構成図である。この照明装置11は、例えばダウンライト等の照明装置であり、照明器具本体12を有する。この照明器具本体12内にはソケット13および反射体14が取り付けられ、ソケット13には上記電球形蛍光ランプ1の口金2がねじ込みにより装着される。   FIG. 5 is a schematic configuration diagram of the illumination device 11 of the present invention. The lighting device 11 is a lighting device such as a downlight, for example, and includes a lighting fixture body 12. A socket 13 and a reflector 14 are attached in the luminaire main body 12, and the base 2 of the bulb-type fluorescent lamp 1 is attached to the socket 13 by screwing.

この照明装置11によれば、電球形蛍光ランプ1の高光束、高発光効率の螺旋形部4eが図5中下方に向いているので、直下照度を向上させることができる。   According to this illuminating device 11, since the high luminous flux and high luminous efficiency spiral portion 4e of the bulb-type fluorescent lamp 1 faces downward in FIG. 5, the illuminance directly below can be improved.

また、電球形蛍光ランプ1の口金2側へ放射される光束を増大させる直状部4fが照明器具本体12の反射体14側に位置して対向しているので、この反射体14により反射される反射光を増加させることができる。   Further, since the straight portion 4f that increases the luminous flux radiated to the base 2 side of the bulb-type fluorescent lamp 1 is located on the reflector 14 side of the luminaire main body 12 and faces the reflector 14, it is reflected by the reflector 14. The reflected light can be increased.
