An electric lamp (10) comprises: a plurality of electrically-powered light sources (such as LEDs 34); at least one electrical connector (35) electrically connected to the light sources; and a structure to which the light sources are mounted with different orientations and to which the connector(s) is/are mounted. The structure has the form of an open, three-dimensional arrangement of, preferably metallic, interconnected mounting portions (21) with gaps therebetween so that ambient air can pass through the gaps and circulate through the arrangement of mounting portions. The light sources are mounted in thermal contact with the mounting portions. The mounting portions are thermally conductive so that they can dissipate heat away from the light sources. By mounting the light sources on and in thermal contact with a thermally conductive structure, heat can readily be dissipated from the light sources, and by arranging the mounting portions three-dimensionally, the light sources can conveniently be oriented in different directions. |
