Abstract
The invention relates to a light bulb comprising a base BA to which a filament FIL is connected, which filament is intended to emita luminous radiation and has turns arranged in spiraling fashion around an axis of revolution AX. Accoring to the invention,the light blub in addition comprises a plurality of hooks H1, H2, and H3, each being in contact with one of the turns of the filament, and being connected to the base BA by means of a support SUP. The invention enables to keep the filament FIL securely in position, which reduces the risk that several turns of said filament will come into contact with the support SUP, thus creating a destructive short-circuit.
