Abstract

<PICT:0981673/C4-C5/1> <PICT:0981673/C4-C5/2> An electroluminescent lamp comprises a moulding of transparent synthetic resin in the form of a strip 3 of parabolic cross-section forming a flat spiral having a spiral electroluminescent filament 4 embedded in the moulding at the focal line of the parabolic strip, and a reflecting coating on the parabolic surface of the moulding. The filament may be embedded in the moulding after applying the reflecting layer, by cutting a groove in the flat face of the moulding. inserting the filament, and filling the groove with a transparent resin. A lens 5 may be secured to the plane portion of the moulding.
