Title:
LED FILAMENT LAMP
Document Type and Number:
WIPO Patent Application WO/2017/116287
Kind Code:
A3
Abstract:
The invention broadens the scope of application of a device by means of improving operational reliability, enhancing the manufacturability of the design, reducing the number of connections and additional elements, allowing for effectively automating the assembly process, and reducing costs. The technical result is achieved in an LED filament lamp, containing a base (1) having a driver (2) installed therein, input terminals of the driver being connected to contacts of the base, and a hermetic envelope (3) made of an optically-transparent material and filled with an insulating, optically-transparent and chemically-inert gaseous substance, with a support leg having a tubulation (4), a stem (5) and two electrodes (6), and with two cases having LED filaments (7) which are connected in parallel via collecting buses (8) within same, said cases being electrically connected in a sequential circuit, a common connection point for the cases being formed by a direct connection of the corresponding buses of the cases, and the buses, which form the terminals of the sequential circuit, being connected via electrodes to corresponding output terminals of the driver.
