Abstract: A lighting device is providing that includes several LED filaments disposed inside a partially transparent external container and connected to anode and cathode output terminals. Each LED filament includes a slimline substrate, a plurality of light-emitting diodes regularly distributed in line. The diodes are sequentially connected in series. Each LED filament further includes an envelope overmoulded around the diodes and the substrate, and two electrodes forming the anode and the cathode of the LED filament protruding from the envelope. The electrodes fixed to two opposite ends of the substrate and connected electrically to the first and last diodes. The external container forms a hollow and slimline component with two opposite ends, and the LED filaments laid out to at least one lighting line where each lighting line includes several LED filaments aligned sequentially and anodes and cathodes are connected to their respective output terminals.
