Abstract
The invention relates to an LED package having a large beam angle of light emitted from an LED, simplifying a shape of a lens and an assembly process, and to a backlight unit using the same. The LED package includes a housing with a seating recess formed therein and at least one LED seated in the seating recess. The LED package also includes a lens having a predetermined sag on an upper side thereof, covering an upper part of the LED. The LED package and the backlight unit using the same can emit light uniformly without bright spots formed in an output screen, uses a simpler shaped lens with an increased beam angle, and minimizes a color mixing region to achieve miniaturization.
