Abstract
A vehicle LED linear lighting module is provide, including at least one printed circuit board, at least one light bar, an optical colloid and a light conductor. The light bar is disposed on the printed circuit board and composed of a plurality of light emitting diodes in a linear lighting and arranged with equal pitches. The optical colloid has a first optical surface, a second optical surface and a third optical surface, and covers the plurality of light emitting diodes in a full coverage. By using different optical surfaces of the optical colloid and the arrangement of the light incident surface and the light exit surface of the optical conductor, the light strip can greatly improve the light effect.
