Abstract

The invention discloses an LED filament lamp bulb with arc-shaped thermal radiation supports and application of the LED filament lamp bulb. The LED filament lamp bulb comprises a lamp head assembly with a driving assembly. The lamp head assembly is connected to a lamp bulb shell internally provided with the two thermal radiation supports with arc-shaped sections. An LED light-emitting assembly is arranged between the two thermal radiation supports. A wire support is arranged in the lamp bulb shell and is provided with a plurality of electric connection wires connected with the driving assembly. The electric connection wires are connected with the LED light-emitting assembly. According to the LED filament lamp bulb with the arc-shaped thermal radiation supports and application of the LED filament lamp bulb, a replaceable, standardized and independent LED electric light source is achieved, and the light-emitting efficiency is improved compared with an integrated LED lamp assembly. Due to a radiation heat dissipation principle, operation can also be conducted in an airtight lampshade, the high-power independent LED electric light source can be achieved, the LED filament lamp bulb is more convenient to assemble structurally, and the structure is more stable and reliable.

Description

technical field [0001] The invention relates to an LED filament light bulb with an arc-shaped heat radiation support 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 pr...
