Abstract

Filament LED (1) comprenant un substrat (2), des diodes électroluminescentes (3) distribuées en au moins une rangée sur une face supérieure (24) du substrat, une enveloppe (4) en matière transparente contenant des particules fluorescentes et recouvrant les diodes, un connecteur anodique mâle (61) et un connecteur cathodique mâle (62) disposés sur une première extrémité (21) du substrat et fixés sur sa face inférieure (23), et un connecteur anodique femelle et un connecteur cathodique femelle disposés sur une seconde extrémité du substrat et fixés sur sa face inférieure, où les connecteurs mâles et les connecteurs femelles sont en complémentarité mâle/femelle. Cette structure de filament LED permet de connecter deux filaments LED bout à bout tout en minimisant, et de préférence tout en évitant, une zone obscure non émissive entre les deux filaments LED.LED filament (1) comprising a substrate (2), light-emitting diodes (3) distributed in at least one row on an upper surface (24) of the substrate, an envelope (4) of transparent material containing fluorescent particles and covering the diodes , a male anode connector (61) and a male cathode connector (62) disposed on a first end (21) of the substrate and fixed on its lower face (23), and a female anode connector and a female cathode connector disposed on a second end of the substrate and fixed on its underside, where the male connectors and the female connectors are complementary male / female. This LED filament structure makes it possible to connect two LED filaments end to end while minimizing, and preferably while avoiding, a non-emissive dark zone between the two LED filaments.
