- Abstract
The behaviour and causes of changes for correlated color temperature (CCT) and radiant spectral power in white LED modules of different design at their encapsulation by optical compounds are investigated. It is shown that CCT of original white LED radiation can both decrease and increase after polymeric covering application. The CCT variation direction is determined mainly by primary lens presence on LED. The variation value of color parameters of white LED modules is determined by created optical surface curvature and spectral characteristics of deposited polymer.
