There is presented a lighting device comprising: several light-emitting filaments (15, 15′) with solid-state light sources and a circuit board (10) with first and second electrically conductive tracks (13, 14) following first and second paths, respectively. Each light-emitting filament (15, 15′) comprises a first electrical contact (19, 19′) electrically connected to the first track (13) at a first point on the first path, and a second electrical contact (20, 20′) electrically connected to the second track (14) at a second point on the second path. The first and second points associated with each light-emitting filament (15, 15′) are arranged on an axis (A) which is non-perpendicular to a tangent (T1) to the first path at the first point and to a tangent (T2) to the second path at the second point. The lighting device may be adapted to emit light from what appears to be a surface according to an observer.
