Abstract
A lamp for a vehicle includes a light source unit, and a light guide lens unit disposed above the light source unit. The light guide lens unit is configured to allow a distance from a center of the light source unit to a peripheral end to be substantially constant. The light guide lens unit includes a reflection unit disposed at a central portion of one surface of the light guide lens unit for reflecting a light incident from the light source unit from a center of the light guide lens unit toward the peripheral end. Further, the reflection unit includes a diffusion lens unit for diffusing the light incident from the light source unit. Accordingly, a first part of the light incident to the light guide lens unit is reflected by the reflection unit, and a second part of the light incident to the light guide lens unit passes through the reflection unit and is incident to the diffusion lens unit.
