LED filaments instead of tungsten wire. Osram Opto Semiconductors presents the Soleriq L 38, the first filament LED in its product range. The long thin shape of the LEDs provides the basis for filament lamps which, in terms of their appearance and their emission characteristics, are more than a match for their incandescent lamp predecessors. The Soleriq LEDs offer an extremely uniform color appearance and quality of light, creating a pleasant atmosphere. They are therefore ideal for aesthetic lighting applications in the home and in hotels and restaurants.
