Each holding structure comprises an essentially longitudinal connection section and an attachment section essentially perpendicular to the connection section.
Claims20
A light engine comprising:
- at least one light-emitting diode (LED) filament;
- and
- a holder comprising:
- a first electrically conductive holding structure having a first attachment section of generally annular shape that is connected with a first end of the at least one LED filament, wherein the first holding structure is configured to be connected with a first electrical contact to provide power to the at least one LED filament;
- and
- a second electrically conductive holding structure having a second attachment section of generally annular shape that is connected with a second end of the at least one LED filament, wherein the second holding structure is configured to be connected with a second electrical contact to provide power to the at least one LED filament;
- wherein the first holding structure and the second holding structure are electrically isolated from each other;
- and
- wherein for at least one of the first electrically conductive holding structure and the second electrically conductive holding structure, the attachment section thereof is connected with a radial section that extends radially inward of the generally annular shape.
