Zusammenfassung:	A lamp (10) using solid-state light emitting sources (24) is configured to be used in a conventional socket. The lamp includes a flexible substrate (22) on which are mounted a plurality of light emitting sources (24), such as light emitting diodes "LEDs" in spaced-apart array. A flexible substrate (22) configured as a generally rectangular panel formed into a cylindrical shape includes a plurality of conductive traces (26,28) to which the LEDs are connected both mechanically and electrically. The flexible substrate (22) is then enclosed within a light transmissive translucent cover (18). The base (12) is shaped and configured to be threaded into a conventional incandescent light socket (one- or three-way) and includes a center terminal 16 through which AC line power is supplied to a power supply in the base. In a different embodiment, the light sources (24) are mounted on a flexible substrate formed as a strand or thread (68) that is wound in a helix around a cylindrical support (76). L'invention concerne une lampe (10) utilisant des sources lumineuses (24) transistorisées configurées pour être utilisées dans une douille classique. Cette lampe comprend un substrat souple (22) sur lequel une pluralité de sources lumineuses (24), telles des diodes électroluminescentes (LED), sont montées espacées. Le substrat souple (22), configuré sous forme de panneau généralement rectangulaire mis en forme cylindrique, comprend une pluralité d'impressions conductrices (26,28) auxquelles les LED sont connectées à la fois mécaniquement et électriquement. Le substrat souple (22) est ensuite enfermé dans une enveloppe translucide (18) transmettant la lumière. Une base (12) est mise en forme et configurée de façon à être vissée dans une douille classique (une ou trois broches) pour lumière incandescente, et comprend une borne centrale (16) à travers laquelle du courant alternatif est fourni à une alimentation disposée dans ladite base. Selon un mode de réalisation différent, les sources lumineuses (24) sont montées sur un substrat souple sous forme de fil ou de filetage (68) enroulé en hélice autour d'un support cylindrique (76).
