20090279322 | LIGHT GUIDE UNIT AND BACKLIGHT ASSEMBLY HAVING THE SAME - A light guide unit includes a body part and a plurality of tunnel lens portions disposed thereon. The tunnel lens portions protrude from an upper surface of the body part in a first direction normal to the upper surface. The tunnel lens portions include an outer surface connected to the upper surface and an inner surface connected to a lower surface of the body part. The outer surface has a concave shape, and respective edges of the concave shape define a first peak and a second peak on the outer surface. The inner surface protrudes in the first direction from the lower surface to define a lamp receiving space. The inner surface has a movement-preventing protrusion which contacts a lamp disposed in the lamp receiving space to prevent the lamp from moving. | 11-12-2009 |
