1. A guide lamp for a vehicle, comprising:
- a sensing unit configured to sense a path change attempt of the vehicle; and
a lamp unit configured to generate a road beam pattern on a surface of a road indicating a direction toward the path change attempt of the vehicle,wherein the lamp unit includes a light source and a light emitter configured to generate the road beam pattern by emitting light generated by the light source in two or more different directions,wherein the light emitter includes a prism lens having an incidence surface and an emission surface,wherein one of the incidence surface or the emission surface of the prism lens has a plurality of surfaces with different angles and different areas with respect to a vertical direction from a longitudinal axis of the lamp unit,wherein the road beam pattern includes a plurality of discrete beam patterns each having a predetermined shape and aligned in one direction,wherein light emitted by the light source that is transmitted through a surface of the plurality of surfaces having a largest area among the different areas of the plurality of surfaces a beam pattern among the plurality of beam patterns that is at a farthest distance from the vehicle along the longitudinal axis of the lamp unit, and wherein the plurality of surfaces with different areas apply the plurality of beam patterns with a substantially uniform illuminance onto the surface of the road.
