[0002] The conventional LED lamp area product usually adopts 12V or 24V power supply, and realizes dynamic light effect through sectional control. In the prior art, typical schemes include: 12V / 60 lamps / 20 sections three-point one control: every section has 3 control points, needs frequent wiring, power supply distance is short, and pressure drop is obvious, resulting in additional power supply or thick cable during construction. And 24V / 60 lamps / 10 sections six-point one control: although voltage promotion reduces the problem of pressure drop, but too many control points (6 points) in a section, resulting in high complexity of control signal, additional wiring and poor flexibility. It can be seen that the prior art scheme has the following problems, that is: wiring is complicated, the number of sections and the number of control points do not match, resulting in power line and signal line interlacing, increasing construction difficulty; Power efficiency is low, low voltage (12V) leads to large current demand, and cable cost is high; When high voltage (24V) is not reasonable, voltage advantage cannot be fully utilized; Control flexibility is poor, too many or too few control points in a section, and light effect and construction convenience cannot be balanced. Therefore, a new type of LED lamp area structure is urgently needed, which optimizes voltage, number of lamp beads and sectional control points to solve the above technical problems. SUMMARY

[0003] The utility model provides a kind of LED lamp area structure, and construction wiring simplification, power efficiency promotion and dynamic control flexibility are realized by optimizing input current, sectional quantity and control point distribution.

[0005] Preferably, each light-emitting section includes a horizontally arranged flexible circuit board, the first end interface and the tail end interface are arranged at both ends of the flexible circuit board, and each lamp bead and the independent addressing chip are distributed on the top of the flexible circuit board.

[0006] Preferably, any two adjacent flexible circuit boards are an integral structure and are electrically connected through the first end interface and the tail end interface.

[0008] Preferably, the lamp strip body is composed of 16 light emitting segments, and the head end interface is used for connecting a 24V power supply and a segmented controller.

[0009] Preferably, each light emitting segment is provided with four lamp beads, and the independent addressing chip communicates with the head end interface by using a single-wire cascade signal control protocol.

[0010] The lamp strip body is directly powered by a 24V power supply, and since it contains 64 lamp beads in total, each of which has a rated voltage of 3V, the 24V voltage is fully utilized and the problem of voltage drop is avoided by designing a series-parallel hybrid circuit, so that each of the 16 lamp beads shares a power supply unit, and at most four power supply units are connected in parallel. Under the action of the segmented controller, the lamp strip body is divided into 16 segments, each of which contains four lamp beads, i.e., one control point, and single-wire serial signal control is realized by using a distributed control chip (such as WS2812B) and an independent addressing chip, each segment is independently addressed, and segmented independent dimming / color adjustment is supported. In addition, a power supply and signal separation design is also realized: the power supply line and the signal line are separated, the power supply line is directly connected in parallel to each power supply unit, and the signal line is connected in cascade by using a single wire, thereby reducing the number of wiring. The lamp strip body has the advantages of simplified construction, reduced current demand for 24V power supply, allowing the use of thinner cables and extending the single power supply distance (up to 10 meters), and reducing the number of control lines by using single-wire cascade signal control.
