Abstract (en)
[origin: EP0346782A1] The lighting lamp (5) comprises a discharge tube (6, 7), a normalised base (10) and an intermediate element (9) disposed between the tube and the base. <??>The lamp is characterised in that an electronic circuit (32) transforming the low frequency of the distribution network into a high frequency in order to supply the tube, is entirely confined inside the normalised base. In particular, the electronic circuit consists of a printed circuit in disc (30) form, vertically carrying the components of the circuit. <??>The lamp, of very small dimensions, is intended to replace an incandescent lamp. <IMAGE>
