    摘要： A lighting device, for example for streetlighting applications, includes an annular arrangement of light radiation sources (L) and a light guide (16) of a light propagating material. The light guide extends along a main axis (X16) with a tubular shape which diverges from an input end (16a), facing said annular arrangement of light radiation sources (L) to collect light radiation therefrom, to an output end (16b) for projecting the light radiation propagating through the light guide (16). On the external surface of tubular light guide (16) there is provided a pattern of grooves (220) extending lengthwise of the tubular light guide (16), and on the inner surface there is provided a sequence of annular ribs (240) extending cross-wise of said main axis (X16), with a proximal collimating facet (240a) and a distal outcoupling facet (240b).

    摘要： The invention relates to an aviation beacon device for a wind turbine. Said aviation beacon device, which is to be arranged on a nacelle of the wind turbine, comprises at least three omnidirectional portions that are annularly and concentrically arranged about a common central axis; each omnidirectional portion comprises a lens portion which is annularly and concentrically arranged about the central axis and which has a radiation plane extending perpendicularly to the central axis and at least one illuminant ring having illuminants, annularly and concentrically arranged about the central axis, for emitting light through the lens portion; each illuminant ring is prepared to emit light in a central emitting direction (370, 371, 372) that extends at a certain emission angle (380, 381, 382) relative to the radiation plane, the emitting direction being dependent on an axial position of the illuminant ring in relation to the lens portion; at least one omnidirectional portion includes at least two axially offset illuminant rings for emitting light at different emission angles.
