ABSTRACT:
Disclosed herein is a Light Emitting Diode (LED) lens for a backlight. The LED lens includes an LED light source, a lens body, and a beam shaping element. The lens body is configured such that the LED light source is accommodated in the lower portion thereof, and light emitted from the LED light source is radiated in vertical and lateral directions of the lens body. The beam shaping element is fastened to the top of the lens body and is configured to adjust light beams radiated through the upper surface of the lens body. Accordingly, the uniformity of luminance and color can be increased and, at the same time, the overall performance of the system can be improved.
