Description

Technical Field

[0001] This utility model belongs to the field of light source and lamp technology, and more specifically, relates to a filament tube module and a lamp. Background Technology

[0002] Filament lamps, combining a retro look with the advantages of modern LED light sources, have been widely used in decorative lighting, commercial lighting, and other fields. Existing filament lamps generally use a glass shell to encapsulate several filament units. The filaments are fixed inside the lamp body by welding or gluing and connected to power terminals via pins to achieve overall light emission.

[0003] However, existing filament lamps generally suffer from the problem of non-replaceable light sources. Once the light-emitting chip in the filament ages, becomes damaged, or the overall brightness decays to an unacceptable level, the user has to replace the entire lamp. Especially in some lamps with complex designs or high prices, this one-piece, non-replaceable light source design not only increases the cost of use but also wastes resources.

[0004] Furthermore, since the light source cannot be replaced, once the filament lamp malfunctions during transportation, assembly, and maintenance, it cannot be restored to use through simple repairs, which seriously affects the practicality and lifespan of the lamp. Utility Model Content
