Optical assembly and vehicle lamp

An optical assembly of a vehicle lamp, comprising:

• a light source allocated to a first light guide, where the first light guide takes a form of an elongate rod;
• and
• a second light guide where the second light guide is a light guide block, and where the thickness of the light guide block is greater than a cross-sectional dimension of the first light guide;
• where the first light guide extends along the second light guide in a superposed fashion and extends along a number of integrally formed fixing structure with the second light guide;
• the first light guide including a first light in-coupling region and a first light out-coupling surface;
• the second light guide including a second light in-coupling surface and a second light out-coupling surface, where the first light out-coupling surface faces the second light in-coupling surface;
• and
• where a light distribution structure is provided on a curved partial segment of at least one of the first light out-coupling surface and the second light in-coupling surface;
• where the first light guide and the second light guide include corresponding curved segments;
• and
• where the light distribution structure is disposed on the first light guide's corresponding curved segment, which is offset from the second light guide in a main exit direction.
