LIGHT-EMITTING DIODE PACKAGE STRUCTURE
First Claim
1. A light-emitting diode package structure, comprising:
- a package carrier;
a plate-like light guiding component, disposed on the package carrier;
a light emitting unit, being capable of emitting a light, disposed on a first portion of an upper surface of the light guiding component and at least exposing a second portion of the upper surface of the light guiding component; and
a sealant, sealing the light guiding component and the light emitting unit, wherein the sealant extracts a first portion of the light directly from the light emitting unit and a second portion of the light from the second portion of the upper surface of the light guiding component.

Abstract
A light-emitting diode package structure includes a package carrier, a light guiding component and a light emitting unit. The light guiding component is disposed on the package carrier. The light emitting unit is disposed on an upper surface of light guiding component relatively distant from the package carrier. A horizontal projection area of the light guiding component is greater than that of the light emitting unit. The light emitting unit is adapted to emit a light beam, and a portion of the light beam enters the light guiding component and emits from the upper surface of the light guiding component. An included angle existing between the light beam and a normal direction of the upper surface ranges from 0 degree to 75 degrees.
