Disclosed is a tubular light source device which includes an optical tube and a light source assembly. The optical tube has a cross section which is hollow. A part of the cross section which is hollow includes an inner flat part as an inner wall of the optical tube. The light source assembly includes a substrate, a plurality of light emitting elements which are arranged on the substrate, and conductive lines. The substrate is attached on the flat part of the optical tube and forms a thermal contact with the inner wall. The light source device further includes a necessary connector and controllers. |
