【０００１】 本考案は、ＬＥＤ投光器の構成にかかわり、蛍光灯器具に 接続できる機構を有し、ＬＥＤおよび商用電源によってＬＥＤを点灯する回路を 内蔵し、蛍光灯器具に装着することによって、他の設備を必要とする事無く、Ｌ ＥＤを点灯し、投光することを特長とする投光器に関する。The present invention relates to the configuration of an LED floodlight, has a mechanism that can be connected to a fluorescent lamp fixture, and has a built-in LED and a circuit for lighting the LED by a commercial power source, and by mounting it on the fluorescent lamp fixture, another The present invention relates to a floodlight which is characterized by lighting an LED and projecting light without requiring equipment.
【０００２】 従来より、たとえば鋼板の圧延において、鋼板の下に蛍光 灯を設置し、鋼板の上に受光素子をならべたものを設置して、該受光素子に光が 到達するか否かで、鋼板の位置を検出する設備が用いられてきた。[0002] Conventionally, for example, in rolling a steel plate, a fluorescent lamp is installed under the steel plate, a light receiving element is arranged on the steel plate, and whether light reaches the light receiving element or not. Equipment has been used to detect the position of the steel sheet.
【０００３】 また一部では、上記の蛍光灯の代わりに、ＬＥＤをならべ たものを投光器として使用しているところもある。In some cases, instead of the above-mentioned fluorescent lamp, an LED array is used as a light projector.
【０００４】 ところで上記のような従来の蛍光灯を設置した設備では蛍 光ランプの寿命が短いため、頻繁に蛍光ランプを交換せさぜるをえず、そのたび に圧延装置を停止するなど負担の大きいものであった。By the way, since the life of fluorescent lamps is short in the equipment in which the conventional fluorescent lamps are installed as described above, it is necessary to frequently replace the fluorescent lamps, and it is burdensome to stop the rolling mill each time. It was a big one.
【０００５】 また、投光器としてＬＥＤをならべたものを使用するには 、すでに設置されている蛍光灯器具を撤去し代わりにＬＥＤを点灯する回路を設 けるなどの負担の大きいものであった。Further, in order to use the LED arrayed as the floodlight, it has been a heavy burden to remove the already installed fluorescent lamp fixture and to provide a circuit for lighting the LED instead.
【０００６】 本考案は上記従来の難点に鑑みなされたもので、すでに設 置されている蛍光灯器具に装着することによって、他の設備を必要とする事無く 、ＬＥＤを点灯し、投光することのできる投光器を供給することを目的とする。The present invention has been made in view of the above-mentioned conventional drawbacks, and by mounting it on a fluorescent lamp fixture already installed, the LED is turned on and the light is projected without the need for other equipment. The purpose is to provide a floodlight that can.
【０００７】 本考案による蛍光灯型ＬＥＤ投光器の構造は、蛍光灯器具 に接続できる機構を有し、ＬＥＤおよび商用電源によってＬＥＤを点灯する回路 を内蔵し、すでに設置されている蛍光灯器具に装着することによって、他の設備 を必要とする事無く、ＬＥＤを点灯し、投光することを特長とする。The structure of the fluorescent lamp type LED floodlight according to the present invention has a mechanism that can be connected to a fluorescent lamp fixture, has a built-in LED and a circuit for lighting the LED by a commercial power source, and can be attached to an already installed fluorescent lamp fixture. By doing so, the LED is turned on and the light is projected without the need for other equipment.
【０００８】この蛍光灯型ＬＥＤ投光器では、すでに設置されている蛍光 灯器具に装着することによって、他の設備を必要とする事無く、投光できるため 、従来蛍光灯を用いていたところでは何ら設備の変更なしに、単に使用している 蛍光ランプの交換の時期に、この蛍光灯型ＬＥＤ投光器に交換するだけで、寿命 の長いＬＥＤ投光器とすることができる。[0008] In this fluorescent lamp type LED floodlight, since it can be projected onto a fluorescent lamp fixture already installed without needing any other equipment, there is no need to use a fluorescent lamp in the past. It is possible to obtain a long-life LED floodlight by simply replacing this fluorescent light type LED floodlight at the time of replacement of the fluorescent lamp in use without changing the equipment.
【０００９】 以下に本考案による蛍光灯型ＬＥＤ投光器の望ましい実施 例を図面に基づき説明する。Hereinafter, a preferred embodiment of a fluorescent lamp type LED projector according to the present invention will be described with reference to the drawings.
【００１０】 第一図は本考案による蛍光灯型ＬＥＤ投光器の望ましい一 例の断面図であり、第２図は同じ蛍光灯型ＬＥＤ投光器の回路のブロック図であ る。FIG. 1 is a sectional view of a preferred example of a fluorescent lamp type LED projector according to the present invention, and FIG. 2 is a block diagram of a circuit of the same fluorescent lamp type LED projector.
【００１１】 すなわち、管１および口金２によって、たとえばＪＩＳ Ｃ７６０１に定められた蛍光ランプと同じ形状となるようにし、蛍光灯器具に接 続できるようにする。蛍光灯器具に装着することによって、電力は口金２を経て ＬＥＤを点灯する回路３に供給され、ここでＬＥＤを点灯するのに適した電力に 変えられ、ＬＥＤ４に供給され、ＬＥＤ４を点灯する。That is, the tube 1 and the base 2 have the same shape as, for example, a fluorescent lamp defined in JIS C7601 and can be connected to a fluorescent lamp fixture. By mounting it on a fluorescent lamp fixture, electric power is supplied to the circuit 3 for lighting the LED via the base 2, where it is converted into electric power suitable for lighting the LED, and is supplied to the LED 4 to light the LED 4.
【００１２】 上記の説明からも明らかなように、本考案による蛍光灯型 ＬＥＤ投光器を用いれば、すでに設置されている蛍光灯器具に装着することによ って、他の設備を必要とする事無く、投光することができるＬＥＤ投光器を供給 することができる。As is clear from the above description, when the fluorescent lamp type LED floodlight according to the present invention is used, it is necessary to install other equipment by mounting it on the already installed fluorescent lamp fixture. Without, it is possible to supply an LED floodlight that can emit light.
