| 主权项 | 1. A lighting device comprising: a plurality of laser light sources, and an optical apparatus for concentrating the light emitted by the laser light sources, wherein the optical apparatus has at least one ring-shaped reflector having a parabolic light reflection surface and at least one light conversion element for light wavelength conversion, which is arranged at the focus of the at least one ring-shaped reflector, and wherein the laser light sources of said plurality of laser light sources are arranged around the ring axis of said at least one ring-shaped reflector so that light emitted by the laser light sources is emitted in directions parallel to the ring axis of the at least one ring-shaped reflector and impinges on a parabolic light reflection surface of said at least one ring-shaped reflector and is reflected towards the focus of the at least one ring-shaped reflector, at which said at least one light conversion element for light wavelength conversion is positioned. | ||
