Patent ID: 10655790

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.
