Abstract
Electroluminescent laminar luminaire comprising a laminar substrate (2), at least one flexible electroluminescent lamp (1) printed on the substrate (2), and electric power supply means of the EL lamp (1) housed together inside an encapsulating casing (8). The latter contains at least one hot-melt adhesive (HMA), preferably EVA, and accurately matches the external shape of the EL lamp (1) and the relief, and the electric power supply means that protrude from the substrate (2), covering them fully without leaving any gaps, constituting a closed, flexible, compact and fluid-tight luminaire (100).
Claims9
An electroluminescent laminar luminaire (100) comprising a laminar substrate (2), at least one flexible electroluminescent (EL) lamp (1) printed on the substrate (2), and an electric power supply means of the EL lamp (1), the substrate (2), the EL lamp (1) and the electric power supply means housed together inside an encapsulating casing (8), characterized in that the encapsulating casing (8) contains at least one hot-melt adhesive (HMA) and the encapsulating casing (8) accurately conforms to an external shape of the substrate (2), the EL lamp (1) and the electric power supply means, with the electric power supply means protruding from the substrate (2), the encapsulating casing (8) covering the substrate (2), the EL lamp (1) and the electric power supply means fully without leaving any gaps, the electroluminescent laminar luminaire (100) being a closed, flexible, compact and fluid-tight luminaire (100).
A method of manufacture of an electroluminescent laminar luminaire (100), comprising the following steps:
- printing on a substrate (2) at least one flexible electroluminescent (EL) lamp (1);
- arranging on the substrate an electric power supply means of the EL lamp (1) to form an assembly comprising the substrate (2), the EL lamp (1) and the electric power supply;
- cold-closing the assembly inside an encapsulating casing (8) containing at least one layer (8′) of a hot-melt adhesive (HMA);
- heating the encapsulating casing (8) to melt the HMA to the assembly, conforming the encapsulating casing (8) to the assembly;
- allowing the encapsulated assembly to cool inside the heated encapsulating casing (8), thus forming a closed, flexible, compact and fluid-tight luminaire.
