Description
本考案は、ＬＥＤチップを発光源とする照明用装置に関するものである。 The present invention relates to an illumination device using an LED chip as a light source.
筒型の管の内部にプリント基板を設け、その上面に複数のＬＥＤチップを搭載した照明装置が作られているが、従来の蛍光灯のあかるさと同じにするにはチップの数を多く使用することが必要である。 A lighting device has been made in which a printed circuit board is provided inside a cylindrical tube and a plurality of LED chips are mounted on the printed circuit board. However, a large number of chips are used to make it the same as a conventional fluorescent lamp. It is necessary.
これはＬＥＤチップの発光面から発光する光の方向が同一となって筒型の管表面から有効に出ていないことによる。 This is because the direction of light emitted from the light emitting surface of the LED chip is the same and is not effectively emitted from the cylindrical tube surface.
本考案は、ＬＥＤチップから出る光を有効にガラス管外に出すためにその発光面の向きを管内面に垂直または垂直に近い角度になるようにしたものである。 In the present invention, in order to effectively emit light emitted from the LED chip to the outside of the glass tube, the direction of the light emitting surface is set to be perpendicular or close to the perpendicular to the inner surface of the tube.
以下、添付図面に従って従来のものと比較して一実施例を説明する。 Hereinafter, an embodiment will be described in comparison with the conventional one according to the attached drawings.
図１は、従来の蛍光灯型ＬＥＤ装置。図２はその内部でプリント基板１とその上に搭載されたＬＥＤチップ２を示す。図３は、その円断面を示す。 FIG. 1 shows a conventional fluorescent LED device. FIG. 2 shows a printed
図４は本考案による蛍光灯型ＬＥＤ管の内部で、プリント基板１１、１２、１３とその上に搭載されたＬＥＤチップ２１を示す。ＬＥＤチップ２１は管の軸に平行に配置されたプリント基板（本図の例では３枚）の上に軸に平行に複数個搭載されている。 FIG. 4 shows printed
ＬＥＤ基板１１、１２、１３が円断面から見て傾いていること、従ってその上に搭載されているＬＥＤチップ２１ａ、２１ｂ、２１ｃの発光面が異なっていることが本考案の特徴である。
図５は本考案の円断面である。図７はＬＥＤから発する光がプリント基板の傾きが違うことでその角度が異なることがわかる。
図８は従来のプリント基板１とその上に搭載されたＬＥＤチップで光の方向が同じである。It is a feature of the present invention that the
FIG. 5 is a circular cross section of the present invention. FIG. 7 shows that the angle of light emitted from the LED differs depending on the inclination of the printed circuit board.
FIG. 8 shows a conventional
図６は本考案の別の例で、プリント基板２１が一枚からなり管に沿った二つの直線で曲げ加工されている。 FIG. 6 shows another example of the present invention, in which the printed
本考案によれば、ＬＥＤチップからの発光が有効に筒型の管外部から出て照明に効率よく利用される。少ないＬＥＤチップで明るさを増し、より明るい照明装置を提供できることは安価に作れることともつながる。 According to the present invention, the light emitted from the LED chip can be effectively used for illumination by exiting from the outside of the tubular tube. The ability to increase the brightness with a small number of LED chips and provide a brighter lighting device also leads to a lower cost.
本考案によって、従来不可能であった明るい蛍光灯型ＬＥＤ管を可能とし、また同じＬＥＤチップの数でより明るいＬＥＤ管を可能とした。 According to the present invention, a bright fluorescent lamp type LED tube which has been impossible in the past is made possible, and a brighter LED tube is made possible with the same number of LED chips.
