[0002] Light strips are a type of lamp widely used in lighting and decoration. They are popular because of their low energy consumption and long life. In existing light strips, constant current chips are needed to output constant current, and constant current chips mostly use epoxy resin molding compounds as packaging shells.

[0016] Reference Figure 1 to Figure 2 A narrow-edge LED light strip includes a substrate 10 and a constant current chip wafer 20 and a plurality of LED lamp beads 30 arranged on the substrate 10. The constant current chip wafer 20 and the plurality of LED lamp beads 30 are connected in series, and one end of the series connection is connected to the positive pole of a power supply, and the other end of the series connection is connected to the negative pole of the power supply.

[0017] In this utility model, reference is made to Figure 1 , as three typical circuit diagrams of the light strip of the utility model, they are respectively an LED light strip with an input of 5V, an LED light strip with an input of 12V and an LED light strip with an input of 24V. The external input voltage is processed by the constant current chip wafer 20 to output a constant current, thereby driving a plurality of LED lamp beads 30 to emit light stably; wherein, since the constant current chip is in the state of a wafer and is not packaged in a shell, the volume occupied by the constant current chip can be greatly reduced. Specifically, firstly, relevant circuits are arranged on the substrate 10, and then the constant current chip wafer 20 and a plurality of LED lamp beads 30 are attached to the substrate 10 and connected to the circuits. When an external power supply is connected, a constant current will be output to drive the LED lamp beads 30 to work; the utility model has the advantages of: realizing constant current output by directly applying the unpackaged constant current chip wafer 20 on the substrate 10, eliminating the large-sized constant current chip packaging shell, reducing the demand for the width of the substrate 10, and being conducive to the miniaturization of the light strip, and having very good practicality.
