Beschreibung
Zusammenfassung:	The invention describes a lighting assembly (1) and a lighting device (10) with improved thermal behavior and a method (100) to manufacture such a lighting assembly comprising at least one point-like light source (2) having a first and a second electrical contact (21, 22), a lead frame (3) comprising metal areas (31) to electrically connect at least the first electrical contact and to spread heat from the point-like light sources via the metal areas, and a plastic layer (5) arranged at least on top of the lead frame, where one or more conductive traces (6) are applied on a first surface (51) of the plastic layer facing away from the lead frame to electrically insulate the conductive traces on the plastic layer from the metal areas of the lead frame. Additional components (4) or the second electrical contact might be connected to the conductive traces.
