Реферат: The present invention provides a multicolor LED assembly packaged with improved and controlled color mixing to create a more uniform color mixture. The assembly includes at least one lens overlying an encapsulant which encapsulates a plurality of LED dies. The lens includes a top surface and a bottom surface with the contour of the bottom surface designed to redirect light from each of the LED dies in different directions towards the top surface of the lens. The contoured shaped of the bottom surface of the lens redirects light from each of the plurality of LED dies such that illuminance and luminous intensity distributions of the plurality of LED dies substantially overlap, wherein the deviation from complete overlap is less than a predetermined amount which is substantially imperceptible to the average human eye.
