The pilot said the aircrew of more than ten other airliners flying above Shanghai also reported the illuminant object, one by one.

据悉，当驾驶航班CZ6554的飞行员于21时51分起飞后，发现的一个“不明发光体”占据了各大版面的头条。 飞行员说：“晚21时左右，CZ6554航班，上海区域，高度一万零七百米发现巨大球状发光天体”。

The LED illuminant can be continuously used for over 20000 hours, which avoids the trouble of frequently replacing the traditional lamp with short longevity.

LED作为发光体使用寿命超过20000小时，解决了传统灯使用寿命短，频繁更换带来的麻烦。

The utility model relates to an image and illuminant device used for medical partial deep hole operations, comprising a computer 1, a bracket 2 and a lamp cap 3.

本实用新型是一种医用局部深孔手术摄像照明装置，包括有计算机1、支架2和灯头3，灯头3是一种同时进行照明和摄像的灯。

This invention is suitable for the reading of single-paged material outdoors or places without lighting equipment at night, and the illuminant is stable and soft.

本发明夜间阅读装置主要应用于于夜间室外或无照明地区时阅读单页资料时的照明使用，使用时于需阅读的纸张背面提供亮光，光源稳定而又柔和。

This is an illuminant estimation algorithm that differs quite dramatically from the previous methods because it requires detailed knowledge of one's imaging sensor.

这个光照估计算法与之前提到的算法有明显的不同，因为这种计算方法要求对成像传感器非常了解。
