Combined Experimental and Monte-Carlo Ray-Tracing Approach for Optimizing Light Extraction in LED COB Modules
Figure 1
Cross-sections of the geometries which have been modelled for evaluating the impact of the encapsulation shape and size on a LED COB performance. (a) Nearly flat encapsulation, with an aspect ratio H/R of 0.3; (b) hemispherical encapsulation; (c) oblong encapsulation, with an aspect ratio H/R = 1.7.
