Abstract:
A light emitting diode, LED, filament arrangement (100), comprising at least one LED filament (120) comprising an array of a plurality of light emitting diodes (140), LEDs, is provided. The LED filament arrangement comprises at least one light distribution element (200a, 200b) comprising a solid, at least partially translucent material at least enclosing the at least one LED filament. The at least one light distribution element has a conical shape and is configured to at least partially refract, and at least partially reflect by total internal reflection, the light emitted from the at least one LED filament during operation.
