The present invention provides an organic EL device utilizing phosphorescence which can be driven at a low voltage, which realizes high luminance and high efficiency, and which has a long lifetime.

本发明提供了可以在低电压下驱动、实现高亮度和高效率并具有长 寿命的利用磷光的有机EL元件。

The super-high-luminance LED Lamp belongs to the luminescence light source, which is effective to prevent the nonnasality mucous membranes from being burned by the over-heated lamp.

超高亮LED灯泡属冷光光源，可防止灯泡过热灼伤口腔粘膜，效果优于现有的光纤冷光源。
