Filament structure, filament structure illumination device and method of manufacturing a filament structure illumination device

摘要

A filament structure (100) is provided for a lighting device (1000) comprising at least two filament elements (1), each of the filament elements (1) comprising a lead frame element (10) having a first end region (11) and a second end region ( 12) and on the lead frame element (10) of each of the filament elements (1) a plurality of light emitting diodes (13) is arranged, and at least one connecting element (2), the first end portion (11) of one of the at least two filament elements (1 ) is connected to the first end region (11) of another of the at least two filament element (1), so that the at least two filament elements (1) are connected in series, wherein the lead frame elements (10) of all filament elements (1) and the at least one connecting element (1) 2) are formed as a one-piece lead frame (20) and wherein the connecting element (2) is shaped and / or bendable such that each of the filament elements (1) of the Filamentst Structure (100) along a lateral surface of an imaginary cone or an imaginary pyramid runs. Furthermore, a lighting device with filament structure and a method for producing a lighting device with filament structure are specified.
