On the Standardization of Thermal Characterization of LEDs

Figure 3: Sketches of some mainstream power LED packages. Unlike two decades ago in the IC world, the junction temperature (Tj) of an LED is not just a performance indicator of the thermal design but also plays a major role in lighting design since many properties of the light output of an LED depend on the absolute junction temperature. This means that thermal management should be an integral part of the system design of an LED based lighting solution, resulting in changing roles of different engineering disciplines in the overall design process - as will be discussed later in more detail.
