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： A lighting device (100), which may be employed e.g. as a retrofit bulb for vehicle lamps, includes a light radiation source (12), e.g. a LED source, and a beam-narrowing optical system (14) facing the light radiation source (12), for propagating a narrowed light radiation beam of the source along a longitudinal axis (X100) of the device (100). Arranged distally of the beam-narrowing optical system (14) along said longitudinal axis (X100), there are moreover provided:
- a light reflector (16),
- a light-driving lens (18),
- a filament-like body (20) including annular reflective surfaces (200) extending around the longitudinal axis (X100) and exposed to light radiation from the light radiation source (12) propagated through the light reflector (16) and the light-driving lens (18),
- a distal mirror member (22) having a reflective surface (220) facing towards the filament-like body (20), to reflect light radiation towards annular reflective surfaces in said plurality of annular reflective surfaces (200).
The light radiation reflected by the annular reflective surfaces (200) of the filament-like body (20) is spread radially from the longitudinal axis (X100) of the device (100).

摘要： A mounting structure (11, 12) for lighting devices (10), for instance, for lamps or retrofit bulbs (10) for vehicle applications, comprises a light generator (L) carrier portion (11) comprising an elongated body (110) extending along a longitudinal axis (X10) and a ring portion (12) fitted on the elongated body (110) of the carrier portion (11). Either the elongated body (110) of the carrier portion (11) or the ring portion (12) carries one or more tooth members (111) protruding towards the other of the elongated body (110) of the carrier portion (11) or the ring portion (12). The other of the elongated body (110) of the carrier portion (11) or the ring portion (12) comprises one or more arch-shaped engagement formations for the tooth member(s) (111), wherein the carrier portion (11) and the ring portion (12) are restrained from mutual displacement along the aforesaid longitudinal axis (X10) by engagement of the tooth member(s) (111) with the arch-shaped engagement formation(s) with the at least one tooth member (111) displaceable along the arch-shaped engagement formation(s) (121) so that the elongated body (110) of the carrier portion (11) can be rotated relative to the ring portion (12) about the longitudinal axis (X10) of the elongated body (110) of the carrier portion (11).
