1. An automotive solid-state headlamp comprising:
a lamp body extending in a longitudinal direction, the lamp body having a rear base portion and a front portion and including a support member and a light-transmissive housing;
a plurality of solid-state light sources arranged on the support member at the rear base portion of the lamp body;
a drive circuitry electrically coupled to the solid-state light sources and arranged at the rear base portion of the lamp body and configured to operate the plurality of solid-state light sources when energized; and
reflector optics arranged at the front portion,
wherein the solid-state light sources are configured to emit light towards the reflector optics, the reflector optics comprising a first reflector optic portion and a second reflector optic portion,
wherein the first reflector optic portion is configured to:
receive the light emitted from the plurality of solid-state light sources when operated by the drive circuitry, and
emit the light toward the second reflector optic portion,
wherein the second reflector optic portion is configured to:
receive the light reflected off the first reflector optic portion, and
emit the light through the light-transmissive housing, and
wherein each of a plurality of first reflective surfaces disposed on the first reflector optic portion extends in an annular region around the longitudinal direction, the longitudinal direction extending from the plurality of solid-state light sources towards the first reflector optic portion.
