LED light pipe

摘要

A light emitting device and method of manufacture are described. In an embodiment, the light emitting device includes a micro LED device, a light pipe around the micro LED device to cause internal reflection of incident light from the micro LED device within the light pipe, and a wavelength conversion layer comprising phosphor particles over the light pipe. Exemplary phosphor particles include quantum dots that exhibit luminescence due to their size, or particles that exhibit luminescence due to their composition.

1. A light emitting device comprising:
a micro LED device mounted on a substrate; a light pipe around the micro LED device; and a wavelength conversion layer over the light pipe, the wavelength conversion layer comprising phosphor particles; wherein the light pipe is designed to allow refraction of incident light from the micro LED device out of the light pipe toward the wavelength conversion layer, and to cause internal reflection and lateral spreading of incident light from the micro LED device within the light pipe.
