Standardization of Performance Criteria for LED Luminaires

This guiding paper is intended to help bring clarity by introducing a universal set of quality criteria that are recently described in two IEC/PAS documents. As a user of LED luminaires it is important to apply the same set of standardised and therefore comparable quality criteria when evaluating manufacturer’s claims. Users of LED luminaires should always ask for LED luminaire specifications measured in compliance with the new IEC/PAS documents. Read more »

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.
