要約(日本語): 高輝度LEDsの開発経緯を簡潔にまとめ、次にその動作機構を実際に観測したJ_F-V_F特性を基にして、LEDの動作機構や再結合現象をパワーデバイス分野のpinダイオードの考え方と対比しながら再検討する。

要約(英語): It's liable that LEDs are much different from high voltage pin diodes. _x000D_ At the small to medium current range, the diffusion current flows in the normal diode and its power losses are aimed to be minimized._x000D_ However, the recombination current flows mainly in the LED and its power loss is aimed to be maximized to get the bright light efficiently. _x000D_ Nevertheless, the electronic operational mechanism of LEDs does not seem to be explained in detail yet._x000D_ In this paper, after introducing brief histories of development on super luminosity LEDs, the operating mechanism and the recombination phenomenon of the LED would be reexamined based on the actually observed If-Vf curves, comparing with those of normal pin diodes.
