Abstract:
1. A vehicle lamp comprising: a semiconductor light emitting device arranged to face toward a front of the vehicle lamp; a first optical member disposed in front of the semiconductor light emitting device; and a second optical member disposed in front of the first optical member, wherein the first optical member comprises a front surface and a back surface, wherein the front surface is configured to internally reflect light from the semiconductor light emitting device toward the back surface, wherein the back surface is configured to internally reflect the light reflected by the front surface back toward the front surface such that the light exits the first optical member from the front surface, and wherein the second optical member is disposed directly in front of the front surface of the first optical member and diffuses the light from the first optical member to form a light distribution pattern; wherein a front surface of the second optical member includes a plurality of lens elements inclined with respect to a vertical direction and a horizontal direction that are configured to obliquely diffuse a portion of the light from the first optical member and a plurality of vertical lens elements that are configured to horizontally diffuse another portion of the light from the first optical member, so as to form a low beam light distribution pattern.
