Abstract: The invention provides a lighting device, comprising a light exit chamber (14), delimited by a light exit body (16), a plurality of light sources (20), positioned within the light exit chamber (14), and arranged to emit light in the direction of the light exit body (16), an optical processing element, adapted to process the light emitted from the plurality of light sources (20), and a transparent antenna element (22), extending into the light exit chamber (14) and positioned relative to the plurality of light sources (20) such that each light source is arranged to transmit light toward the antenna element, wherein said transparent antenna element (22) is separate from the optical processing elements, wherein the transparent antenna element (22) being transparent for the light emitted by the plurality of light sources (20), and the antenna element (22) comprises: a transparent conductive material that is self-supporting.

Abstract: Disclosed is a lighting device (10) comprising a heat sink (30) having an annular portion (31) including an annular surface portion (33) delimiting a central aperture (37), said annular surface portion (33) carrying a plurality of SSL elements (50); and a bulbous member (20) cooperating with the heat sink (30), said bulbous member (20) having a first surface portion (21) opposite said SSL elements (50) and a second surface portion (22) extending from said first surface portion (21) through said central aperture (37); wherein the bulbous member (20) is used as a light guide member for light emitted by the plurality of SSL elements (50). A luminaire including such a lighting device (10) is also disclosed.
