Abstract

The invention discloses an LED lamp filament bulb with a semicircular heat radiation ring. The LED lamp filament bulb comprises a lamp cap assembly 2 with a drive assembly 3. The lamp cap assembly 2 is connected to a bulb shell 6. The bulb shell 6 is internally provided with the heat radiation ring 5.3 with the semi-arc section. The heat radiation ring 5.3 is provided with an LED light emitting assembly 1. The LED light emitting assembly 1 is composed of a plurality of LED lamp filament assemblies. Each LED lamp filament assembly comprises a plurality of LED lamp filaments, the two ends of each LED lamp filament are provided with electric connection terminals, and the electric connection terminals at the two ends of each LED lamp filament are connected with two heat and electricity conduction terminal supports correspondingly. A wire support 4.1 is arranged in the bulb shell 6 and provided with a plurality of electric connection wires 4.2 connected with the drive assembly 3. The electric connection wires 4.2 are connected with the LED light emitting assembly 1. According to the LED lamp filament bulb with the semicircular heat radiation ring, a replaceable and standard independent LED electric light source is achieved, and compared with an integral LED lamp assembly, the light emitting efficiency is improved. On the basis of the radiation heat dissipation principle, the LED lamp filament bulb can run in a closed lampshade, and the large-power independent LED electric power source can be achieved. In addition, the LED lamp filament bulb is more convenient to assemble in structure, and the structure is more stable and firmer.

Description

technical field [0001] The invention relates to an LED filament light bulb with a semicircular heat radiation ring and an application thereof, belonging to the technical field of LED lighting. Background technique [0002] The current LED lighting focuses the industry on LED chips. After obtaining LED chips, mid-stream and downstream enterprises need to design packaging, driving, optics, heat dissipation, lamp structure, etc., and finally formed the current general LED lighting industry, especially high-power Lighting, integrated LED light assembly mode. There are six major systemic defects in this assembly mode. ① At the application level, there is a lack of universal interchangeable standardized light sources, and terminal lighting assembly products present too many individual characteristics. ② At the level of industrial structure, centering on LED chips is not the optimal structure for LED lighting, resulting in many complexities and uncertainties in the design and prod...
