Description

Technical Field

[0001] The utility model relates to the technical field of LED lamps, in particular to a flexible electrodeless lamp panel without a rectifier power supply and a lamp belt composed of the same. Background Art

[0002] LED (Light Emitting Diode) light strips are a popular product in modern lighting technology. They are widely used in home, commercial, architectural decoration and stage lighting due to their energy saving, environmental protection, long life and easy custom shapes. LED light strips are usually composed of a series of closely arranged small LED beads, which are encapsulated on a soft substrate such as polycarbonate (PC) or polyurethane (PU), making them highly flexible and bendable.

[0003] The working principle of LED light strips is based on the characteristics of semiconductor diodes, that is, they conduct and emit light under forward bias. However, since the household power grid usually provides alternating current (AC), and the substrate circuit of existing LED light strips is relatively simple, they can usually only work properly under direct current (DC), which requires a rectifier bridge circuit to convert AC into DC. In addition, in order to prevent the LED light strip from being damaged by reverse voltage, the positive and negative poles of traditional LED light strips must be correctly connected during installation, otherwise the light strip may fail to light up or be damaged.

[0008] LED diodes are mounted on the pair of lamp bead pads that are arranged opposite to each other. On the same row of lamp bead pads, the positive and negative poles of the LED diode pins that are adjacent to each other are different from each other.

[0013] The first conductive module is in the shape of a staggered horizontal strip with a bent middle portion, and two lamp bead soldering pads at the front end and two lamp bead soldering pads at the rear end of the first conductive module are arranged along different rows.
