1. An aircraft headlight, comprising:
at least one light source;
a housing accommodating the at least one light source; and
an integrated, single-piece optical structure, which includes:
a light transmissive protective cover portion, forming an outer light emission surface of the headlight, wherein the integrated, single-piece optical structure including the light transmissive protective cover portion closes the housing at least on one side thereof; and
at least one reflector portion, arranged for directing light that is emitted by the at least one light source through the light transmissive protective cover portion, wherein the at least one reflector portion protrudes into an inner space of the housing thereby positioning the at least one light source between the light transmissive protective cover portion and the at least one reflector portion,
wherein the integrated, single-piece optical structure substantially has a u-shape or a v-shape in at least one cross-section, with the light transmissive protective cover portion forming a first leg and the at least one reflector portion forming a second leg of the u-shape or the v-shape,
wherein the integrated, single-piece optical structure is an injection-molded structure and is made from a polymer based material, and
wherein a metallic reflective coating is provided at the at least one reflector portion.
