LAMP COMPRISING A FLEXIBLE PRINTED CIRCUIT BOARD

摘要

The present invention relates to a lamp (1) comprising at least two solid state light sources (9), a envelope (2) comprising a light transmittable surface (3) adapted to transmit light from the solid state light sources, a heat sink (4) extending from inside the envelope to the outer surface of the envelope such that it divides the envelope into at least two compartments (16), and a flexible printed circuit (7) at which the solid state light sources are mounted. The flexible printed circuit is attached to the heat sink such that the solid state light sources are distributed in both of the compartments. The present invention is advantageous in that manufacturing, and in particular assembly, of the lamp is facilitated since the number of components to assemble is reduced and the need of soldering (e.g. of wires to circuit boards) is reduced.
