Light-emitting diode and backlight system using the same

摘要

A light-emitting diode (LED) ( 10 ) includes a chip body ( 103 ), an encapsulation can ( 105 ) surrounding the chip body, and a base ( 106 ) supporting the encapsulation can and the chip body thereon. Numerous fluorescent particles ( 1050 ) are provided in the encapsulation can. With the fluorescent particles, light beams from the chip body are diffused and attain wider irradiation angles. A backlight system ( 900 ) includes a light guide plate ( 20 ), and a number of the above-described LEDs disposed adjacent to the light guide plate. Light beams having wide irradiation angles are emitted from the LEDs and enter the light guide plate. This enables a light emitting surface of the light guide plate to have highly uniform brightness.
