Abstract
Solid-state lighting devices including light-emitting diodes (LEDs), and more particularly integrated secondary optics into LED chip cover structures for improved optical emission of high intensity LEDs is disclosed. Optical elements are integrated as a secondary optic onto one or both surfaces of a chip cover structure, where the chip cover structure may be referred to as a primary optic. The integrated secondary optic may be formed directly on one or both surfaces of the chip cover structure. The integrated secondary optic is purposely built to be coupled with the light emission of the LED to emit a desired emission profile. In this regard, a final luminaire may be provided with increased efficiency either by improving the coupling of the LED into a conventional secondary optic or in some cases by removing the need for a conventional secondary optic all together.
