Abstract: The present invention relates to a screw-in type base for a lighting device being arranged to be mounted in a socket comprising a socket bottom conductor is provided. The base (100, 200, 300) comprising a threaded tubular enclosure (102) extending along an axial direction between a first (102a) and a second (102b) end portion of the enclosure (102), a base bottom conductor (103, 203, 311) arranged to be in electrically conductive contact with a light source (106) of the lighting device (400), and arranged to make electrically conductive, biased contact with the socket bottom conductor when the lighting device (400) is mounted in the socket, wherein the base bottom conductor (103, 203, 311) comprises a compliant thin-walled member (105, 205, 308) arranged such that the base bottom conductor (103, 203, 311) is, relative to the enclosure (102), movable in the axial direction in response to engagement with the socket bottom conductor when the lighting device (400) is mounted in the socket. The present invention also relates to a lighting device (400) comprising the base.

Abstract: A lighting device (1, 11, 21) comprising a substrate (4, 14, 24), a plurality of light sources (3, 13, 23), and a housing (2, 12, 22) of a light transmissive material. The substrate has a first side (4a, 14a, 24a) and a second side (4b, 14b, 24b) and the plurality of light sources are arranged on the first side of the substrate. The light sources have a common general output direction. The housing is arranged to transmit light surrounding the substrate, having a first portion (2a, 12a, 22a) of said housing and a second portion (2b, 12b, 23b) of the housing arranged substantially opposite the first portion with respect to the substrate. The plurality of first optical elements (6, 16, 26) may be arranged substantially opposite the output direction of the plurality of light sources along the first portion of the housing facing the first side of the substrate. The substrate is adapted to allow transmission of light. The plurality of first optical elements are arranged to transmit part of the light emitted by the light sources and reflect part of the light emitted by the light sources through the substrate towards the second portion of the housing.
