温升60K

应指在室温下上升了60度。

一般标准都是指25度环境下的温升,也就是60+25=85度

是60度+你所测的环境温度.

请弄清温升与温度是两个词语！

我记得我们测试时是这样的：取一杯水放置一天后的温度与被测温度之间的差就是温升！

温度？是绝对值。
温升，是相对值，可以理解为温度的增量。
数值上 温升=测量点温度-环境温度。

瞎扯，毫无科学道理！

正确的室温测试方法：
The ambient temperature is to be measured by means of a thermocouple immersed in a bath of 15 milliliters of mineral oil in a glass container. The oil bath is to be placed:
a) At the same level as the horizontal plane formed by a line that passes through the portable luminaire halfway down its vertical length; and
b) At least three unit diameters from the product horizontally.
