Abstract
There is presented a lighting device comprising: several light-emitting filaments (′) with solid-state light sources and a circuit board () with first and second electrically conductive tracks () following first and second paths, respectively. Each light-emitting filament (′) comprises a first electrical contact (′) electrically connected to the first track () at a first point on the first path, and a second electrical contact (′) electrically connected to the second track () at a second point on the second path. The first and second points associated with each light-emitting filament (′) are arranged on an axis (A) which is non-perpendicular to a tangent (T) to the first path at the first point and to a tangent (T) 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.
