Description

Technical Field

[0001] The utility model belongs to the technical field of LED light strips, and particularly relates to a novel LED light strip structure. Background Art

[0002] The light strip is the main structure of the lighting fixture. A conventional light strip includes a light strip substrate and several LED lamp beads welded on the light strip substrate, and is equipped with a current-limiting resistor set on the light strip substrate. The current-limiting resistor is mainly used to control the brightness of the LED light strip. When in use, since the resistance value of the current-limiting resistor set on the light strip remains unchanged, as the distance increases, the voltage at both ends of the light string continues to decrease, causing the operating current on the welded light strip substrate to decrease. At the same time, the LED lamp beads on conventional light strips are mostly set in series. When one of the components or electrical appliances is damaged, it cannot be used again, and cannot be cut and combined and connected as needed, which will affect its convenience and effectiveness to a certain extent, so its applicability and practicality are limited.

[0007] The light strip substrate is provided with cutting areas at equal intervals, and the cutting areas are provided with a positive electrode pad, a negative electrode pad and a center line pad;

[0008] The positive electrode pad is arranged between adjacent positive power supply wires, the negative electrode pad is located between the negative power supply wires, and the center line pad is located between the two middle lines.
