Summary: | A lighting device (1) is provided. The lighting device (1) comprises a light-transmissive enclosure (10) and alight source (30). The light-transmissive enclosure (10) has an outer surface (11) and an inner surface (12) opposite to the outer surface (11). The inner surface (12) at least in part forming a cavity (20). The light-transmissive enclosure (10) has an opening (15) lying in a transverse plane (P1). The light source (30) is arranged on the transverse plane (P1), or on a side of the transverse plane (P1) opposite of the light-transmissive enclosure (10), and configured to emit light into the cavity (20). The light-transmissive enclosure (10) is arranged around a longitudinal axis (L), the longitudinal axis (L) lying in a longitudinal plane that is perpendicular to the transverse plane (P1). The light-transmissive enclosure (10) has a first part (101) and a second part (102) separated from each other by the longitudinal plane (P2). The first part (101) is shaped as a first parabolic segment or a first elliptical segment having a first focal point (13) that is located on the transverse plane (P1). The second part (102) is shaped as a second parabolic segment or a second elliptical segment having a second focal point (14) that is located on the transverse plane (P1). The light source (30) is arranged between the first focal point (13) and the second focal point (14). |
