Abstract

An electric lamp 10 comprises a plurality of electrically-powered light sources 34 (such as LEDs); at least one electrical connector 54 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 a shell 100 and is assembled from a plurality of separately formed shell portions 88,90. A method of manufacture of the lamp comprising the steps of: providing at least two shell portions and a circuit board 92; assembling the shell portions and the circuit board so that the shell portions are mechanically connected to each other to form a hollow shell, the circuit board is contained within the shell, and an electrical input to the circuit board is externally accessible; attaching a plurality of light emitting devices to the shell; and electrically connecting the light emitting devices to the circuit board.
