以上説明したように、本発明は 、LED体により低電流で比較的高い輝度の光を出射できるので、消費電力の低減を図ることができる。 As described above, the onset Ming, because it emits a relatively high intensity of light at a low current by the LED body, it is possible to reduce power consumption. また、構成部品を収納する細長管が破損しても、蛍光燈のように水銀が封入されておらず破損した細長管に水銀が付着しないので、この細長管の廃棄処理を安全かつ簡単に行なえる。 Also, elongated tube for accommodating the component is broken, because the mercury does not adhere to the elongated tube mercury is damaged not been sealed as a fluorescent lamp, perform the disposal of the elongated tube safely and easily that. さらに、細長管の両端に装着したブッシングで細長管内の所定位置にプリント基板を簡単に保持できるとともに、細長管に電極ピンを設けた口金具を容易に一体化できる。 Furthermore, it is possible easily hold the printed circuit board at a predetermined position of the elongated tube in a bushing mounted at each end of the elongated tube can be easily integrated with the cap member provided with electrode pins in the elongated tube.
【0072】 [0072]
また、リード線からなる接続体の両端をプリント基板および口金具に設けた電極ピンに半田付けすることにより、プリント基板と電極ピンとの電気的接続を簡便に行なうことができる。 Furthermore, by soldering the electrode pins provided at both ends of the connection member consisting of lead wire to a printed circuit board and the cap member can be performed easily electrical connection between the printed circuit board and the electrode pin.
【0074】 [0074]
また、細長管が嵌合するリング溝の径および口金具が嵌合する取付筒部の径の異なる複数個のブッシングを簡単に用意することができ、それらブッシングを適宜変えることで、既存する径の異なる各種の細長管と既存する径の異なる各種の口金具とを組み合わせて使用できる。 Also, elongated and tubes can diameter and the cap member of the ring groove easily prepared differently plurality of bushings diameters of the mounting cylinder portion fitted to the fitting, by changing them bushing appropriate, existing combined different variety of the elongated tube and the different variety of the cap member of preexisting size diameters can be used.
【0075】 [0075]
また、ブッシングが高温状態になってリング溝の内周壁が高熱により外方に膨出しても、このリング溝の内周壁と細長管の内壁との間の隙間が逃げ代となっており、しかも上記の隙間に介在する接着剤が熱で硬化しないので上記の膨出による細長管の内壁に加わる力が小さくなる。 Also, it bulges outward inner wall by high heat of the ring groove Bed ashing becomes a high temperature condition, has become the a relief allowance gap between the inner wall and the elongated tube inner wall of the ring groove, Moreover force applied to the inner wall of the elongated tube by the bulging is reduced since adhesive interposed said gap is not cured with heat. したがって、使用中にブッシングが高温状態になっても細長管を破損させることを防止でき、ブッシングを細長管に確実に固定できる。 This prevents the bushing may damage the elongated tube even when the high temperature during use, can be reliably fixed to the bushing elongated tube.
