Claim 0:
1. A lighting device comprising:
a plurality of light-emitting filaments, wherein each light-emitting filament comprises:
a carrier,
two electrical contacts attached to the carrier,
a plurality of solid-state light sources mounted on the carrier and electrically connected to the first and second electrical contacts, and
an encapsulant comprising a translucent material, wherein the encapsulant at least partially encloses the solid-state light sources so as to receive light emitted by the solid-state light sources;
two rigid electrically conducting wires which extend in parallel and across which the filaments are arranged in parallel electrically,
wherein the light-emitting filaments are arranged consecutively along the two rigid electrically conducting wires and extend therebetween,
wherein one of the electrical contacts of each light-emitting filament is electrically connected to one of the rigid electrically conducting wires at a first point on said one of the rigid electrically conducting wires and the other electrical contact of each light-emitting filament is electrically connected to the other one of the rigid electrically conducting wires at a second point on said other one of the rigid electrically conducting wires, and
wherein the first and second points associated with each light-emitting filament are arranged at a distance from each other on an axis, and wherein the axis of each light-emitting filament is non-perpendicular to a tangent to said one of the rigid electrically conducting wires at the first point and to a tangent to said other one of the rigid electrically conducting wires, at the second point.
