Abstract:
A light emitting device (1) comprising a light exit surface (41) and at least one light source (5) configured to, in operation, emit light, wherein the light emitting device is configured to provide a light output at the light exit surface (41), the light output comprising at least one peak intensity in a first direction (A) and an intensity cut-off in at least one second direction (B), where the intensity in the at least one second direction (B) is less than 10 % of the peak intensity in the first direction (A), and wherein the light emitting device (1) comprises a plurality of sparkling elements (6) arranged in the optical path of at least a part of the light emitted by the at least one light source (5), at least two sparkling elements of the plurality of sparkling elements (6) being configured and arranged to be visible when observed from a viewing position corresponding to the at least one second direction (B).
