Description

本考案は電球に係り、特に多方向的な領域の出射光を有する電球に関するものである。   The present invention relates to a light bulb, and more particularly to a light bulb having outgoing light in a multidirectional area.

従来の電球は、壁または天井等のあらゆる平面に設けられ、周囲の環境に光を照射するとともに、所定の環境に対して特別な照明を行なうか否かを決める。
一般に、LED電球は、天井や、壁または電球ベースに固定され、その配置位置が固定され移動できないようになっているので、LED電球の照射可能な範囲は、固定で照射方向が単一になり、照射面が狭い。一旦、照射の輝度が足りなく、方向が良くなく、或いは範囲が大きくない場合には、好ましい照明範囲を得るために、電球の設置数を大幅に増加したり、電球の照射方向を調整しなければならない。
しかしながら、このような従来の方式は、時間や労力がかかるだけではなく、全体の美観性が破壊される可能性もあり、さらに照明具の購入コストが高くなるといった問題点がある。 A conventional light bulb is provided on every plane such as a wall or a ceiling, irradiates light to the surrounding environment, and determines whether or not to perform special illumination for a predetermined environment.
In general, LED bulbs are fixed to the ceiling, wall, or bulb base, and their placement positions are fixed so that they cannot move. The irradiation surface is narrow. Once the illumination intensity is insufficient, the direction is not good, or the range is not large, the number of installed bulbs must be significantly increased or the illumination direction of the bulbs must be adjusted to obtain the preferred illumination range. I must.
However, such a conventional method not only takes time and labor, but also has a problem that the overall aesthetics may be destroyed, and further, the purchase cost of the lighting device increases.

本考案の一つの目的は、導光棒を提出し、中空本体の先端に開口、側壁に複数のスリットを備えることによって、発光素子の光が該導光棒により案内され、多方向性に光を出射させるようにして、従来のLED電球の光の一方向への出射の問題を解決することにある。   One object of the present invention is to provide a light guide rod and to provide an opening at the tip of the hollow body and a plurality of slits in the side wall, so that light from the light emitting element is guided by the light guide rod and light is emitted in a multi-directional manner. Is to solve the problem of light emitted from the conventional LED bulb in one direction.

前記目的を達成するためには、本考案による電球は、電球ベースと、中空本体と、発光素子と、導光棒とを含む。前記中空本体が前記ベース前段に装着され、前記中空本体は複数のスリットを有し、前記複数のスリットは、前記中空本体の側壁に開設される。前記発光素子が前記ベースの一端に装着され前記中空本体内に収容される。前記導光棒が前記発光素子の上縁に配置される。前記発光素子からの光は、前記導光棒により案内され、前記導光棒の先端から、並びに前記導光棒の周縁から前記複数のスリットを介して光を出射する。   To achieve the above object, a light bulb according to the present invention includes a light bulb base, a hollow body, a light emitting element, and a light guide rod. The hollow main body is attached to the front stage of the base, the hollow main body has a plurality of slits, and the plurality of slits are opened on a side wall of the hollow main body. The light emitting element is mounted on one end of the base and accommodated in the hollow body. The light guide bar is disposed on an upper edge of the light emitting element. Light from the light emitting element is guided by the light guide rod, and is emitted from the tip of the light guide rod and from the periphery of the light guide rod through the plurality of slits.

前記電球は、さらに、前記中空本体の外面に対応して嵌合する絶縁シェルを含む。   The light bulb further includes an insulating shell that fits in correspondence with the outer surface of the hollow body.

前記中空本体の側壁は、複数の離間する壁体からなり、前記スリットは、壁体と壁体との間に位置される。   The side wall of the hollow body is composed of a plurality of spaced wall bodies, and the slit is positioned between the wall bodies.

本考案は、中空本体の先端に開口を備え、側壁に複数のスリットを備えることによって、発光素子の光を導光棒に案内し、導光棒の先端から、並びに導光棒の周縁からスリットを介して光を出射して、大きな照射領域を備えるよう光線を多方向性に出射することができる。したがって、従来の電球の出射光の照射範囲が狭い問題を解決できる。
また、絶縁シェルを中空本体の外面に対応して嵌することによって、使用者が中空本体の壁体に触ったりして触電や火傷されてしまうことを防止できる。 The present invention has an opening at the tip of the hollow body and a plurality of slits on the side wall to guide the light of the light emitting element to the light guide rod, and slits from the tip of the light guide rod and from the periphery of the light guide rod. The light can be emitted in a multidirectional manner so as to have a large irradiation area. Therefore, the problem that the irradiation range of the emitted light of the conventional bulb is narrow can be solved.
In addition, by fitting the insulating shell in correspondence with the outer surface of the hollow body, it is possible to prevent the user from being touched or burned by touching the wall of the hollow body.
