Abstract
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 diffusion structures (1050) are provided on the encapsulation can. With the diffusion structures, 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 LEDs as per the above. The LEDs are 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 exit surface of the light guide plate to have highly uniform brightness.
