摘要： A polarized semiconductor light emitting device includes a semiconductor structure having a first conductivity semiconductor layer, an active layer and a second conductivity semiconductor layer sequentially stacked. Also, the semiconductor structure further includes a plurality of light guide parts defined by a plurality of grooves arranged along a predetermined direction. The grooves extend from the second conductivity semiconductor layer with a depth reaching at least the active layer, and the light guide parts have a length greater than a width thereof to selectively emit a polarized component in a length direction thereof.

摘要： 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.
