Optical device for controlled color mixing |
| abstract |
The present invention provides a multicolor LED assembly packaged with improved and controlled color mixing to produce more uniform color mixing. The assembly includes at least one lens overlying an encapsulant encapsulating a plurality of LED dies. The lens includes a top side and a bottom side, the contour of the bottom side being designed to redirect light from each of the LED dies in different directions towards the top side of the lens. The contoured bottom surface of the lens redirects light from each of the plurality of LED dies, such that the illuminance and intensity distribution of the plurality of LED dies sufficiently overlap, where the deflection from full overlap is in the average human eye. It is less than a predetermined amount which is hardly detectable. |
