Light device with hollow column light guide for vehicle

A light device for vehicle for providing a light with an elongated distribution pattern, comprising:

• a plurality of emitting modules, comprising a main emitting element and two secondary emitting elements bilaterally arranged beside the main emitting element;
• a light condensing lens;
• and
• a light guide, composed of at least two chassis, the adjacent two chassis have a plurality of adjacent side walls assembling a plurality of hollow columns corresponded with the plurality of emitting modules, the plurality of hollow columns defining a light incident side and a light output side away from each other, the plurality of emitting modules and the light condensing lens respectively mounted on the light incident side and the light output side,
• wherein the adjacent side walls of the adjacent two chassis are extended from the light incident side to the light output side to define a plurality of light inlets of the hollow columns nearby the plurality of emitting modules and a plurality of light outlets of the hollow columns nearby the light condensing lens, each of the light outlets having a long and narrow boundary, an elongated direction of the long and narrow boundary is the same as an elongated direction of the elongated distribution pattern, wherein the adjacent side walls are formed by protruding or indenting shapes from the adjacent two chassis.
