Abstract
Disclosed herein is a light device of a vehicle including: a light emitting diode module emitting light; and a light guide plate having a side on which the light emitted from the light emitting diode module is incident and emitting the light incident on the side to perform surface emission upwardly, in which the light guide plate has a plane shape including at least one concave portion and the light emitting diode module is installed in the at least one concave portion. According to the exemplary embodiments of the present invention, when the light guide plate used in the light device installed at the rear of the vehicle to perform the surface emission is formed in a horseshoe shape or a ring shape, the light emitting diode module may be installed at a concave position of the horseshoe shape or the light emitting diode module may be installed along a ring-shaped inner side, thereby uniformly performing the surface emission over the whole of the light guide plate.
