  • a first inner volume delimited by a first arcuate section of the tubular body and the carrier; and

    a second inner volume delimited by a second arcuate section of the tubular body and the carrier, wherein;

    the carrier supports a plurality of solid state lighting elements arranged to emit a luminous output into the first inner volume; and

    the first arcuate section comprises a transparent region and a translucent region obscuring the solid state lighting elements, said transparent region extending from the translucent region to the carrier;

    whereinthe carrier comprises a central region extending along the length of the tubular body, and defining a recess in which the solid state lighting elements are located, which recess prevents the entirety of the solid state lighting elements from being directly observable through the transparent region of the first arcuate section,wherein light generated by the solid state lighting elements is diffused by the translucent region, andwherein the light is partially reflected by the translucent region and directed toward the transparent region.
