Abstract
A filament lamp (10) comprising a conductor element (100) that connects to at least two filaments (15). The conductor element is ring-shaped and formed of a continuous length or piece of bent conductive wire. The conductor element comprises a plurality of protrusions (111, 112, . . . , 118) to which a respective filament is attached and/or electrically connected. The conductor element lies in a first plane (410). Each of the plurality of protrusions is configured to provide a surface to which a respective filament of the filament lamp is electrically connectable. The surface is inclined with respect to the first plane.
Claims14
A filament lamp comprising at least one conductor element and at least two filaments, each conductor element being formed of a single, continuous length of bent conductive wire and comprising a substantially ring-shaped frame with a plurality of protrusions to which a respective filament of the filament lamp is attached to and/or electrically connected;
- wherein the conductor element lies in a first plane;
- and each of the plurality of protrusions is configured to provide a surface to which a respective filament of the filament lamp is electrically connectable, wherein the surface is inclined with respect to the first plane.
A method for use in manufacturing a filament lamp comprising at least two filaments, the method comprising:
- obtaining a single, continuous length of conductive wire;
- and
- bending the single continuous length of conductive wire to form a conductor element comprising a substantial ring-shaped frame with a plurality of protrusions, wherein the conductor element lies in a first plane;
- and each of the plurality of protrusions is configured to provide a surface being inclined with respect to the first plane;
- and
- for each protrusion:
- resting a respective filament onto the surface of the protrusion;
- and
- soldering the filament onto the surface of the protrusion to make electrical and mechanical connection.
