SIDE-EMITTING LED LENS, AND BACKLIGHT UNIT AND DISPLAY DEVICE COMPRISING SAME

摘要

The present invention relates to a side-emitting LED lens for side-emitting light from an LED and to a backlight unit and display device comprising said LED lens. More particularly, the present invention relates to a side-emitting LED lens in which the upper surface, having no reflection coating, is formed to totally reflect the light incident thereto, and in which light that is not totally reflected at the upper surface and discharged upwardly through the upper surface can be minimized, when forming a reflection surface for total reflection of light side-emitted from an LED chip.
