LED FILAMENT LAMP

WIPO Patent Application WO/2018/072360

A1

An LED filament lamp is provided, comprising a bulb, a supporting rod, at least two power cables, and at least two LED filament bars. Each LED filament bar comprises a substrate, an LED chip disposed on the substrate, and an electrode plate fixed to two ends of the substrate. One end of the electrode plate is electrically connected to the LED chip on the substrate, and the other end thereof is electrically connected to the electrode plate of another LED filament bar or to one end of a power cable, such that the LED filament bar and the at least two power cables form an electrically connected structure. One end of the supporting rod is fixed to the bulb, and the other end thereof is connected to at least one LED filament bar so as to support the LED filament bar. The supporting rod of the LED filament lamp of the present invention replaces a stem and a metal wire of an existing LED filament lamp, and the electrode plates of the LED filament bars are directly electrically connected to each other in an inventive manner, such that the LED filament lamp has the advantages of a highly reliable structure and a simple production process.
