I have been staring at datasheets for surface mount LEDs and other surface mount components, and it appears to me that LED manufacturers use the term "ambient temperature" to mean the temperature of the mounting surface rather than using the term in the traditional sense for other, especially leaded, components, which in that sense refers to ambient air temperature.
Unfortunately, I have not been able to find a reference, such as the test method or a picture of a test fixture. And the manufacturer, while trying to be helpful, either does not understand the question or cannot provide an answer that seems sensible. So, I am looking toward forum members who have a firm understanding of what "ambient" means in the context of a surface mount light emitting diodes to er...shed some light on this mystery (sorry! )
