Light emitting diode structure

Abstract

A light emitting diode structure includes a substrate and a light emitting unit. The substrate has a protrusion portion and a light guiding portion. The protrusion portion and the light guiding portion have a seamless connection therebetween, and a horizontal projection area of the protrusion portion is smaller than that of the light guiding portion. The light emitting unit is disposed on the protrusion portion of the substrate. The light emitting unit is adapted to emit a light beam, and a portion of the light beam enters the light guiding portion from the protrusion portion and emits from an upper surface of the light guiding portion uncovered by the protrusion portion.
