In an embodiment a reflector optical system includes a reflector body having a rotational symmetry about a longitudinal axis and including a first reflector optic portion having a substantially concave shape and a second reflector optic portion extending along the longitudinal axis, the first reflector optic portion facing the second reflector optic portion, wherein the first reflector optic portion includes a plurality of first reflective surfaces and the second reflector optic portion includes a plurality of second reflective surfaces in spaced light-receiving relation to the plurality of first reflective surfaces.

Reflector optics for a vehicle retrofit headlamp

An automotive solid-state headlamp includes 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 light sources and arranged at the rear base portion of the lamp body and configured to operate the plurality of 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 including a first reflector optic portion and a second reflector optic portion and wherein each of a plurality of first reflective surfaces disposed on the first reflector optic portion extend in an annular region around the longitudinal direction from the plurality of solid-state light sources towards the first reflector optic portion.

Vehicle retrofit headlamp having reflector optic portions facing each other

In an embodiment an automotive solid-state headlamp includes 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 disposed in 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, and a drive circuitry electrically coupled to the light sources and arranged at the rear base portion of the lamp body and configured to operate the plurality of light sources when energized, wherein the plurality of light sources, when energized, are configured to cause the solid-state lamp to emit, through the light-transmissive housing (a) a luminous flux of at least 1500 lumens +/&#x2212;10% when energized with a 13.2 Volt test voltage, or of at least 1750 lumens +/&#x2212;10% when energized with a 28 Volt test voltage, or (b) a luminous flux of at least 1350 lumens +/&#x2212;10% when energized with a 13.2 Volt test voltage, or of at least 1600 lumens +/&#x2212;10% when energized with a 28 Volt test voltage.
