Rapid innovation in light emitting diode (LED) lighting products challenges lighting
product manufacturers to reduce the product design cycle. Currently, LED component
datasheets provided in industry are available with limited information for the digitalized
design of LED products. The European project Delphi4LED developed and demonstrated
methods, processes, and tools that facilitate the usage of LED components in a digital
design flow, with the result that they are deployable more rapidly in LED lighting
products (the so-called “Industry 4.0” approach). This approach has been demonstrated
through the example of a LED-based luminaire with a multi-domain compact model (MDCM)
for the LEDs. In this paper, earlier work is extended to further demonstrate and examine
the developed digital design flow using the MDCM. The influence of variations in the
input data, arising from variations in measured LED samples, on the final operating
parameters is investigated. Additionally, the results and the required computation
times are compared to those obtained with compact thermal model (CTM) using a different
commercial software tool.
