Abstract
Disclosed is a light unit. The light unit includes a printed circuit board formed thereon with a plurality of LEDs and a light guide member having receiving holes to receive the LEDs. At least one round part having a predetermined curvature is formed at an edge defined in an intersection between an upper surface and an inner surface of the receiving hole. Since the round part is formed at the edge in the receiving hole receiving the LED at the portion of the light guide member, the light distribution is improved so that the light efficiency is increased.
