The present disclosure provides a light emitting diode (LED) apparatus. The LED apparatus includes an LED emitter having a top surface; and a phosphor feature disposed on the LED emitter. The phosphor feature includes a first phosphor film disposed on the top surface of the LED emitter and having a first dimension defined in a direction parallel to the top surface of the LED emitter; a second phosphor film disposed on the first phosphor film and having a second dimension defined in the direction; and the second dimension is substantially less than the first dimension.

Structure and method for LED with phosphor coating

An optical emitter is fabricated by bonding a Light-Emitting Diode (LED) die to a package wafer, electrically connecting the LED die and the package wafer, forming a phosphor coating over the LED die on the package wafer, molding a lens over the LED die on the package wafer, molding a reflector on the package wafer, and dicing the wafer into at least one optical emitter.

Wafer level reflector for LED packaging

The present disclosure provides one embodiment of an illumination structure. The illumination structure includes a light-emitting diode (LED) device on a substrate; a lens secured on the substrate and over the LED device; and a diffuser cap secured on the substrate and covering the lens, wherein the lens and diffuser cap are designed and configured to redistribute emitting light from the LED device for wide angle illumination.

Wide angle based indoor lighting lamp

An optical emitter includes micro-structure phosphor coating on a light-emitting diode die mounted on a package substrate. The micro-structures are transferred onto a micro-structure phosphor coating precursor by patterning and curing the precursor or by curing the precursor through a mold. The micro-structures are half spheroids, three-sided pyramids, or six-sided pyramids.
