Abstract
A light-emitting device includes a transparent substrate with a light emitting structure formed on one side of the substrate and a transparent layer formed on the opposing side of the substrate. The refractive index of the transparent layer is greater than the refractive index of the substrate. A light-emitting device includes a package cup having a reflective sidewall and a light emission surface and a light emitting diode (LED) embedded in the package cup. The LED comprises a transparent substrate and a transparent layer formed on the substrate. The reflective sidewall has a first portion in a central area of the package cup and a second portion in a peripheral area of the package cup, the first portion reflects light emitted from the transparent layer to the second portion and, then, the second portion further reflects the light received from the first portion to the light emission surface of the package cup.
