A light-emitting assembly (80) comprises a plurality of light-emitting diodes (81) and at least one connection conductor (82) for providing electrical connections between poles of light-emitting diodes (81). The connection conductor (82; 182) may be provided as a layer (82) on a support or holding member (84) for the diodes, or as a layer on a cover (92) covering the diodes. Power transmitting conductors for providing electrical power to the light-emitting diodes are provided. A heat conductive element connects the assembly to an external part. The assembly may be formed as a so-called pellet (10) and is intended mainly for use in instruments for hardening dental fillings, wherein there is a need for transporting heat away from a distal end of a dental instrument at which the pellet is positioned. |
