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 ССT 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.
