以上に述べた結果から明らかなように、今まで無駄にしていた蛍光灯の照明に用いられていない光を用いて、ＬＥＤを用いた照明、ＰＣ冷却用ファンモータの駆動、個人用クーラに用いられるペルチェ素子を充分稼動させることができることが判った。
As is clear from the results described above, using light that has not been used for the illumination of fluorescent lamps that has been wasted until now, using LED, driving the fan motor for PC cooling, and personal cooler It has been found that the Peltier element can be operated sufficiently.
このシステムを、さらに最適化して商品化できれば、大きな節電が可能であり、計画停電の実施に対する対応や地球温暖化の防止、環境破壊の抑制を図りながら、照明や個人用クーラを用いて個々人が特に我慢することなく、猛暑の夏を快適に過ごすことができることも夢ではない。
If this system can be further optimized and commercialized, significant power savings will be possible. Individuals will be able to use lighting and personal coolers while responding to planned power outages, preventing global warming, and controlling environmental destruction. It is not a dream to be able to spend the hot summer comfortably without being particularly patient.
以上では利用の対象に、照明、回転機、ペルチェ素子を上げたが、ラジオや動画映像の視聴などにも利用できることはもちろんであり、さらに蓄電器を使うことで電力需要時刻をずらすなどにも用いることができることは言うまでもなく、広い用途や可能性が考えられる。
In the above, lighting, rotating machines, and Peltier elements have been raised as objects of use, but of course they can also be used for radio and video viewing, etc., and also used for shifting power demand times by using capacitors. Needless to say, a wide range of uses and possibilities are conceivable.
本発明は、以上に述べたように、オフィスや家庭などで通常用いられている蛍光灯の実際には照明に寄与しない光エネルギーで、ＬＥＤなどの照明を点灯しファンモータやペルチェ素子を稼動させることができるので、事業所、事務所、工場、家庭などで個人用の冷房装置などに用いる広く大きな利用可能性が考えられ、きわめて重要な意義がある。
As described above, the present invention lights a light such as an LED and operates a fan motor or a Peltier element with light energy that does not actually contribute to lighting of a fluorescent lamp normally used in an office or home. Therefore, it can be used widely for personal cooling devices in offices, offices, factories, homes, etc., and is extremely important.
