Title:
FLEXIBLE LAMP STRIP
Document Type and Number:
WIPO Patent Application WO/2022/089269
Kind Code:
A1
Abstract:
A flexible lamp strip, which relates to the technical field of lighting electronics. The flexible lamp strip comprises: a flexible substrate (1); a flexible lamp strip printed circuit (2) laid on a surface of the flexible substrate (1), wherein the flexible lamp strip printed circuit (2) includes at least one group of circuits, which are connected in parallel, each group of circuits includes at least one pair of welding electrodes (22) which are used for connecting to light-emitting elements (3) in series and are formed of a first conductive material, and metal plating layers (4) formed of a second conductive material are formed on the welding electrodes (22); and the light-emitting elements (3), the number of which is consistent with the number of welding electrodes (22), wherein each light-emitting element (3) is connected to the corresponding welding electrode (22) by means of the metal plating layer (4). By means of forming good metal plating layers (4) on welding electrodes (22) in a flexible lamp strip printed circuit (2), the stability of the combination of the welding electrodes (22) and light-emitting elements (3) is improved, and the contact resistance at connection positions thereof is reduced, thereby reducing the power consumption of the flexible lamp strip printed circuit (2) and ensuring the normal use of the flexible lamp strip.
