The lighting device (8) comprises a light source (9) and a lens (11), which are arranged along an optical axis, and a reflector unit (10), which is externally arranged around the optical axis. A lens light cone (13) is formed on the lens and a reflector lighting area (12) formed on the reflector unit are generated by light from the light source. The lens, the reflector unit and the light source are matched with one another. The lens is provided, such that the lens substantially detects only the portion of the light from the light source. |
