    摘要: A lighting device (1) comprising: a substrate defining a plane; at least one solid-state light source mounted on the substrate, an outer light-transmissive envelope (2), and a light-transmissive wall which is arranged at a circumference of the substrate and which has an extension along and is curved towards an optical axis (A) of the lighting device (1). The light-transmissive wall comprises an edge portion distal to the substrate, which edge portion is adapted to diffuse light from the at least one solid-state light source such that a shadow on the outer light-transmissive envelope (2) is blurred, the shadow being caused by an electrical component mounted on the substrate and blocking light emitted by the at least one solid-state light source.
