1. A lamp comprising:
a light source configured to output light into the lamp, wherein the light source is located at a rear side of the lamp;
a light output part located at a front side of the lamp spaced apart from the light source, and configured to output the light output from the light source after the light is input into the rear side of the lamp by the light source; and
a shield part configured to shield a first portion of the light output from the light source such that the first portion of the light is prevented from reaching the light output part, wherein the shield part is located between the light source and the light output part with respect to a forward/rearward direction of the lamp which extends from the rear side of the lamp to the front side of the lamp,
wherein the shield part includes:
a front area defining a front side of the shield part and which is configured to receive an output reflected light from the light output part and to direct this output reflected light away from the light output part to reduce glare from the lamp, wherein the output reflected light is a portion of the light output from the light source which has reached the light output part and which has been reflected by the light output part toward a rear side of the lamp,
a reflection area configured to reflect the first portion of the light output from the light source, wherein the reflection area extends from a rear end of the front area of the shield part toward the rear side of the lamp, and
an extension area extending from a rear end of the reflection area,
wherein the front area of the shield part extends toward the front side of the lamp and is inclined toward a lower side of the lamp with respect to a light output optical axis which is an optical axis of the light output part, and
wherein the reflection area extends to a rear side to be inclined to a lower side with respect to the light output optical axis, and the extension area extends to an upper side to be inclined to a rear side.
