Abstract
A light emitting filament device comprising a carrier extending in a longitudinal direction and having a first main surface, a second main surface opposite to the first main surface, and two side surfaces interconnecting the two main surfaces. Optoelectronic components are disposed on the first main surface of the carrier. A first converter layer is arranged on the first main surface of the carrier and covers the optoelectronic components. A second converter layer is arranged on the second main surface of the carrier. The carrier is designed at at least one location along the longitudinal direction such that at least one of the two side surfaces includes an angle with the first main surface of greater than 90°. The carrier is trapezoidal in cross-section at the at least one location.
