  • Patent number: 10161570
    Abstract: Disclosed is a lighting device (100) comprising a tubular body (120), said tubular body comprising a carrier (130) mounted inside the tubular body such that the tubular body comprises a first inner volume (102) delimited by a first arcuate section (121) of the tubular body and the carrier; and a second inner volume (104) delimited by a second arcuate section (124) of the tubular body and the carrier, wherein the carrier supports a plurality of solid state lighting elements (32) arranged to emit a luminous output into the first inner volume; and the first arcuate section (121) comprises a transparent region (123) and a translucent region (122) obscuring the solid state lighting elements, said transparent region extending from the translucent region to the carrier; wherein the carrier (130) comprises a central region extending along the length of the tubular body (120), and defining a recess in which the solid state lighting elements (32) are located, which recess prevents the solid state lighting elements (32)

  • Patent number: 10125957
    Abstract: An environmentally responsible, optically efficient, low glare lighting device comprises: a tubular body (1); a first plurality of solid state light emitting elements (2) arranged on a first surface of a first carrier (3) inside said tubular body; and a flexible reflective sheet (4) covering said first surface and a first part of an inner surface of the tubular body (1) to an extent (6) sufficient to obscure direct visibility of the light emitting surface of the first light emitting elements (2) if viewed through a light outlet portion (5) from a location external to the tubular body (1), wherein said light outlet portion includes a second part of the inner surface that is not covered by the flexible reflective sheet. A convenient method for manufacturing the device is also described.

  • Patent number: 9951927
    Abstract: There is provided a lighting device (100) comprising a first tubular body (120), a second tubular body (130) within the first tubular body (120), and a support structure within the first tubular body (120). The support structure supports a plurality of Solid State Lighting (SSL) elements (160) on a support surface, said SSL elements being arranged to emit light under a range of angles including a first range. The support structure is fixed within the first tubular body (120) by the first tubular body (120) and the second tubular body (130). The support structure comprises a tube receiving member (156) extending from the support surface, said tube receiving member engaging with the second tubular body (130).
