Patent ID: 8018151

Claim:
A quasi-optical LED package structure for increasing color render index and brightness, comprising: a substrate unit having at least one substrate body and at least two chip-placing areas formed on the at least one substrate body; a light-emitting unit having at least one first light-emitting module for generating a first color temperature and at least one second light-emitting module for generating a second color temperature, wherein the at least one first light-emitting module has a plurality of first light-emitting chips electrically disposed on one of the chip-placing areas of the substrate unit, and the at least one second light-emitting module has a plurality of second light-emitting chips electrically disposed on the other chip-placing area of the substrate unit; a frame unit having at least two annular resin frames surroundingly formed on a top surface of the substrate body by coating, wherein the at least two annular resin frames respectively surround the at least one first light-emitting module and the at least one second light-emitting module in order to form at least two resin position limiting spaces above the substrate body; and a package unit having at least one first translucent package resin body and at least one second translucent package resin body both disposed on the substrate body and respectively covering the at least one first light-emitting module and the at least one second light-emitting module, wherein the at least one first translucent package resin body and the at least one second translucent package resin body are limited in the at least two resin position limiting spaces.
