Title:
FILAMENT FIXING STRUCTURE AND FILAMENT LIGHT STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2019/109978
Kind Code:
A1
Abstract:
A filament light structure comprises a helical shaped filament (1), a support assembly (2) configured to support the filament (1), such that the filament (1) maintains the helical shape, and a fixing seat (3) configured to support the support assembly (2). The support assembly (2) comprises a support portion (003) configured to connect to the fixing base (3), and two or more bearing portions (002) located on different horizontal planes and configured to bear the filament (1). The support portion (003) is provided on the fixing base (3). The bearing portion (002) is provided on the support portion (003). The filament (1) encircles the support portion (003) and is provided in an incremental helical shape on the bearing portions (002). In the filament light structure, the filament (1) is formed into a helical shape by means of a simple and low-cost technique. The helical filament (1) is capable of efficiently emitting light in all directions, thereby resolving the issues of interrupted light sensing and an inability to emit light from multiple angles and multiple layers, and significantly improving the light emitting efficiency of an LED filament.
