Abstract:
A filament lamp structure, relating to the field of LED lighting. The filament lamp structure comprises a fixing base (1) and multiple LED light-emitting assemblies (2) fixed on the fixing base (1). The LED light-emitting assembly (2) comprises an elongated substrate (20), an LED light-emitting chip set (21) arranged on the substrate (20), and a connecting portion (22) located at a middle portion of the LED light-emitting assembly (2). The multiple connecting portions (22) are distributed in an intersecting manner and insulated from each other. The multiple LED light-emitting chip sets (21) are arranged in parallel. The present invention is configured to enable emitted light to be more uniform, and to enable independent control of the LED light-emitting chip sets (21) on the multiple LED light-emitting assemblies (2) inside a filament lamp, such that the filament lamp structure has a wider dimming and color adjustment range and a wider range of applications.
