FILAMENT STRUCTURE, LIGHTING DEVICE HAVING A FILAMENT STRUCTURE, AND METHOD FOR PRODUCING A LIGHTING DEVICE HAVING A FILAMENT STRUCTURE

摘要

The invention relates to a filament structure (100) for a lighting device (1000), which has the following: at least two filament elements (1), wherein each of the filament elements (1) has a leadframe element (10) having a first end region (11) and a second end region (12) and a multiplicity of light-emitting diodes (13) is arranged on the leadframe element (10) of each of the filament elements (1), and at least one connecting element (2), which connects the first end region (11) of one of the at least two filament elements (1) to the first end region (11) of another of the at least two filament elements (1), such that the at least two filament elements (1) are connected in series, wherein the leadframe elements (10) of all the filament elements (1) and the at least one connecting element (2) are formed as a one-piece leadframe (20), and wherein the connecting element (2) is shaped and/or bendable in such a way that each of the filament elements (1) of the filament structure (100) extends along a lateral surface of an imaginary cone or an imaginary pyramid. The invention further relates to a lighting device having a filament structure and to a method for producing a lighting device having a filament structure.
