BACKLIGHT MODULE AND A LIGHT-EMITTING-DIODE PACKAGE STRUCTURE THEREFOR
First Claim
1. A light-emitting-diode (LED) package structure, comprising:
- a substrate;
an LED chip, disposed on the substrate;
a plastic package body, disposed on the substrate and covering the LED chip, wherein the plastic package body comprises a light-converging part and a light-scattering part, the light-converging part comprising a first axis, the light-scattering part comprising a second axis and the first axis intersecting the second axis, wherein the center point of the light-converging part and the center point of the light-scattering part are at the position where the second axis and the first axis intersect; and
two leading legs, each of which comprising one terminal electrically connected to the LED chip.

Abstract
The LED package structure includes a substrate, an LED chip, a plastic package body, and two leading legs. In addition, the LED chip is arranged on the substrate and covered by the packaging plastic body. Moreover, the plastic package body contains a light-converging part and a light-scattering part, in which the light-converging part has a first axis and the light-scattering part has a second axis. In addition, the first axis of the light-converging part intersects the second axis of the light-scattering part. Furthermore, one terminal of each of the two leading legs is electrically connected to the LED chip while another terminal extends out of the packaging plastic body. Because the LED package structure can converge light and scatter light in different directions, the backlight module implementing the LED package structure has the advantage of a shorter light-mixing distance and better light utilization.
