Abstract
The disclosure herein provides photon conversion, extraction and distribution structures, devices, and methods for light emitting devices. The structures, devices, and methods described herein can improve the efficiency and/or light distribution of light emitting devices.
Claims19
A light emitting device:
- an LED light source comprising at least one light emitting diode (LED) and an encapsulation encapsulating the LED, the LED being configured to emit light beams of a first color;
- phosphor materials that absorb the first color from the LED and emit light beams of at least another color and that are blended in transparent materials to form a wavelength conversion layer;
- and
- a photon conversion, extraction, and distribution (PCED) structure placed over the LED encapsulation, the PCED structure comprising a body defined by a bottom, a top and a side, the PCED structure body being configured to receive via the bottom and direct to the top light beams from the LED encapsulation.
