應指在室溫下上升了60度。

一般標準都是指25度環(huán)境下的溫升,也就是60+25=85度

是60度+你所測的環(huán)境溫度.

請弄清溫升與溫度是兩個詞語！

我記得我們測試時是這樣的：取一杯水放置一天后的溫度與被測溫度之間的差就是溫升！

溫度？是絕對值。
溫升，是相對值，可以理解為溫度的增量。
數(shù)值上 溫升=測量點溫度-環(huán)境溫度。

瞎扯，毫無科學道理！

正確的室溫測試方法：
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.
