Description

本発明は、ＬＥＤランプに関し、更に詳しくは、蛍光ランプを本来の光源とする照明装置に、前記蛍光ランプに代わって用いられるＬＥＤランプに関する。   The present invention relates to an LED lamp, and more particularly, to an LED lamp used in place of the fluorescent lamp in an illumination device that uses a fluorescent lamp as an original light source.

ＬＥＤ（Light Emission Diode）ランプは、蛍光ランプに比べて、寿命が長く、消費電力も小さい。このような理由から、蛍光ランプに代わる光源として注目されている。   An LED (Light Emission Diode) lamp has a longer lifetime and lower power consumption than a fluorescent lamp. For these reasons, it has attracted attention as a light source that can replace fluorescent lamps.

ＬＥＤランプを駆動するためには、直流電源が必要となる。このため、蛍光ランプを本来の光源とする既存の照明装置では、ＬＥＤランプを直ちに使用することができない。そこで、蛍光ランプを光源とする照明装置で、手軽に使用することが可能なＬＥＤランプが、種々提案されている（例えば、特許文献１参照）。   In order to drive the LED lamp, a DC power source is required. For this reason, in an existing illumination device that uses a fluorescent lamp as an original light source, the LED lamp cannot be used immediately. Thus, various LED lamps that can be easily used with illumination devices that use fluorescent lamps as light sources have been proposed (see, for example, Patent Document 1).

特許文献１に開示されたＬＥＤランプは、本来蛍光ランプの口金が接続されるソケットによって、両端が支持された状態で照明装置に取り付けられ、使用される。   The LED lamp disclosed in Patent Document 1 is used by being attached to a lighting device in a state where both ends are supported by a socket to which a base of a fluorescent lamp is originally connected.

However, few existing lighting devices have a connector or the like connected to a commercial power source. Therefore, the LED lamp according to Patent Document 1 is not necessarily highly versatile with respect to existing lighting devices.

本発明は、上述の事情の下になされたもので、既存の照明装置で広く利用可能なＬＥＤランプを提供することを目的とする。   The present invention has been made under the above-described circumstances, and an object thereof is to provide an LED lamp that can be widely used in existing lighting devices.
