• a plurality of solid-state light sources configured to emit light according to a light direction, each light source having a light source center and each light source defining a light source plane, which is a plane perpendicular to the light direction which contains the corresponding light source center;
• and
• a light guide with a reception inlet which projects an optical profile on a closest light source plane according to the light direction, the optical profile having an optical center;
• wherein the light sources are arranged to project light beams to the reception inlet of the light guide in such a way that at least 70% of the light source centers are closer to the optical profile than to the optical center,
• wherein each light source comprises a case which has a case surface with a side between 1 mm and 3 mm, and
• wherein each light source is surrounded by a copper area which is greater than 3 times an area of the case surface.
