Abstract
A lamp module includes a light source unit that generates light; a light guide unit that guides the light incident on an incidence portion from the light source unit to be emitted to an emission portion; and an optical unit that transmits the light emitted from the light guide unit to allow a predetermined beam pattern to be formed. In particular, the optical unit includes a plurality of lenses disposed in a vehicle width direction, and the emission portion includes a plurality of emission surfaces disposed in the vehicle width direction to correspond to the plurality of lenses.

A lamp module comprising:
- a light source unit that generates light;
- a light guide unit that guides the light incident on an incidence portion from the light source unit to be emitted to an emission portion;
- and
- an optical unit that transmits the light emitted from the light guide unit to allow a predetermined beam pattern to be formed,
- wherein the optical unit includes a plurality of lenses disposed in a vehicle width direction,
- wherein the emission portion of the light guide unit includes a plurality of emission surfaces disposed in the vehicle width direction such that each of the emission surfaces directs at least a portion of the light from the light source unit to a corresponding lens of the plurality of lenses of the optical unit.
A vehicle lamp configured to allow a predetermined beam pattern to be formed by at least one lamp module,
- wherein the at least one lamp module includes a plurality of lamp modules disposed in a vehicle width direction,
- wherein each of the plurality of lamp modules includes:
