Description

technical field

[0001] The invention relates to an LED lighting source, in particular to an LED filament lamp and an assembly method thereof. Background technique

[0002] LED filament lamp is a kind of LED lighting device with LED filament as light source, usually includes a transparent lamp housing, LED filament is set in the lamp housing, and gas is filled in the lamp housing, and finally realizes LED lighting. LED filament can also be called LED light strip, and LED filament lamp can also be called LED bulb, bulb lamp, etc. Regardless of its name, as long as it adopts a similar structure, it is called LED filament lamp here.

[0003] In the prior art, the LED filament lamp in the prior art includes a core column in the lamp housing, several LED light strips and glass columns. When assembling, it is necessary to install the metal guide at one end of the LED light strip on the glass by welding. Then install the glass column on the core column, and then connect the wires o...
