有单独Adaptor 供电的LED 移动台灯，做温升，耐久测试电压为多少伏？
如台灯的额定参数为： 3.5VDC 700mA 2.5W
是电源电压调到场264V然后插入ADAPTOR 连接台灯做温升，耐久测试吗？

是插入ADAPTOR , 电源电压调到264V, 然后连接台灯做温升，耐久测试

不过我看到一份ITS报告，是直接用直流电压给灯来供电，而不是用Adaptor来供电呀! 有点不明白呀

如果ADAPTOR 是可以用手直接和灯具分开的连接方式, ITS的测试法是对的, 因灯具是三类灯.

adaptor 是可分离的, 拿上面的灯来说3.5VDC 700mA 2.5W, 那电压怎么调呀

灯泡是什么就可以按标准要求来做, 此处测试电压以光源为判定依据吧.

LED 灯属于下面的哪一种呀？

The test voltage for the luminaire shall be as follows.
– Filament lamp luminaires other than ELV: that voltage which produces 1,05 times the
rated wattage of the test lamp (see Annex B) except that heat test source (HTS) lamps
are always operated at the voltage marked on the lamp.
– Tubular fluorescent and other discharge lamp luminaires and ELV luminaires with
tungsten filament lamps: 1,06 times the rated voltage or the maximum of the rated
voltage range.
– For motors contained in luminaires: 1,06 times the rated voltage (or the maximum of the
rated voltage range of the luminaire).
Exception
For determination of the average tem

哪一种都不是，我们一般用1.06倍额定电压
