Usually, it has a three-wire structure, that is, a substrate, a group of white light LED lamp beads, a group of warm white light LED lamp beads, a power line and two signal lines located on the substrate. The power line is used to provide working voltage for the white light LED lamp beads and the warm white light LED lamp beads, and the two signal lines respectively control the brightness of a group of white light LED lamp beads and a group of warm white light LED lamp beads, so as to realize color temperature adjustment. However, in this kind of light belt, there are 3 wire harnesses on the substrate, which makes the width of the substrate larger, and at the same time increases the wiring cost, which is not conducive to the miniaturization of the light belt;

[0023] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.
[0024] In the description of the present utility model, the meaning of "a plurality of" is more than two. Understandings such as "greater than", "less than", "exceeding", etc. do not include the number itself, and understandings such as "above", "below", "within", etc. include the number itself. If there is a description of "first" and "second", it is only for the purpose of distinguishing technical features and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.
[0025] In the description of the present utility model, it should be understood that when it comes to orientation descriptions, such as the orientations or positional relationships indicated by "up", "down", "front", "back", "left", "right", etc., they are based on the orientations or positional relationships shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation to the present utility model.
[0026] In the present utility model, unless otherwise clearly defined, terms such as "arranged", "installed", "connected", etc. should be understood in a broad sense. For example, it can be directly connected, or indirectly connected through an intermediate medium; it can be fixedly connected, or detachably connected, or integrally formed; it can be mechanically connected; it can be the communication inside two elements or the interaction relationship between two elements. Those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.
[0027] Referring to Figures 1 to 4 , a two-wire light strip that can be arbitrarily cut, includes a substrate 10, a first conductive wire 21, a second conductive wire 22, and a plurality of LED lamp groups 30;
[0028] The first conductive wire 21 is externally disposed on the substrate 10 and extends along the length direction of the substrate 10. One end of an external power source is connected to the first conductive wire 21 to serve as a first signal;
[0029] The second conductive wire 22 is externally disposed on the substrate 10 and extends along the length direction of the substrate 10. The other end of the external power source is connected to the second conductive wire 22 to serve as a second signal;
[0030] The LED lamp groups 30 are arranged on the substrate 10 and one end is connected to the first conductive wire 21 and the other end is connected to the second conductive wire 22. The LED lamp groups 30 include at least one resistor, at least one positive white light bead, and at least one warm white light bead;
[0031] The light strip can be cut with the LED lamp groups 30 as the cutting unit, and the positive white light beads and the warm white light beads can emit light separately according to the accessed first signal and second signal to generate positive white light or warm white light; or emit light simultaneously to generate light with different color temperatures.
[0032] In the present utility model, during use, when white light illumination is required, a first signal is input from one end of the first conducting wire 21, and no second signal is input from one end of the second connecting wire 22. That is, one end of the first conducting wire 21 serves as the positive electrode, and one end of the second connecting wire 22 serves as the negative electrode. At this time, the positive white light LED beads are in a forward conduction state and can emit light normally, while the warm white light LED beads are in a reverse cut-off state and cannot emit light. Thus, the overall illumination presents white light; when warm light illumination is required, a second signal is input from one end of the second connecting wire 22, and no first signal is input from one end of the first conducting wire 21. That is, one end of the second connecting wire 22 serves as the positive electrode, and one end of the first conducting wire 21 serves as the negative electrode. At this time, the warm white light LED beads are in a forward conduction state and can emit light normally, while the positive white light LED beads are in a reverse cut-off state and cannot emit light. Thus, the overall illumination presents warm light; when color temperature adjustment is required, a first signal is input from one end of the first conducting wire 21, and a second signal is input from one end of the second connecting wire 22, and the first signal and the second signal are alternately input with a relatively high frequency. If a lower color temperature is required at this time, the duty cycle of the first signal is controlled to increase, while the duty cycle of the second signal is controlled to decrease, so that the brightness of the positive white light LED beads increases and the brightness of the warm white light LED beads decreases. Thus, the overall illumination presents light with a lower color temperature; if a higher color temperature is required at this time, the duty cycle of the first signal is controlled to decrease, while the duty cycle of the second signal is controlled to increase, so that the brightness of the positive white light LED beads decreases and the brightness of the warm white light LED beads increases. Thus, the overall illumination presents light with a higher color temperature.
[0033] When cutting is required, the LED lamp group 30 is used as the minimum cutting unit for cutting. And since the first conducting wire 21 and the second connecting wire 22 are externally disposed on the substrate 10 and extend along the length direction of the substrate 10, any position of the first conducting wire 21 and the second connecting wire 22 can serve as the connection point of the external power supply, realizing arbitrary cutting and arbitrary wiring.
[0034] The advantages of the present utility model are as follows: Through the above structure, not only can the two-color adjustment of the light strip be realized through two connecting wires, reducing the wiring difficulty on the substrate, but also the light strip can be arbitrarily cut with the LED lamp group as the cutting unit, and arbitrary wiring can be carried out after cutting, which has very good practicability.
[0035] Referring to Figure 1 and 3 , as the first embodiment of the present utility model, the external power supply is set to DC 24V. The LED lamp group 30 includes a positive white light LED bead LED1, a warm white light LED bead LED2, and a resistor R1. The positive electrode of the positive white light LED bead LED1 and the negative electrode of the warm white light LED bead LED2 are connected to the first conducting wire 21. The negative electrode of the positive white light LED bead LED1 and the positive electrode of the warm white light LED bead LED2 are connected to the second conducting wire 22 through the resistor R1. The working voltage of the positive white light LED bead LED1 and the warm white light LED bead LED2 is 12V.
[0036] Reference Figure 2 and 3 As the second embodiment of the present utility model, the external power supply is set to DC 24V. The LED lamp group 30 includes a positive white light lamp bead LED1, a warm white light lamp bead LED2, a positive white light lamp bead LED3, a warm white light lamp bead LED4, and a resistor R1. The positive white light lamp beads LED1, the warm white light lamp beads LED2, the positive white light lamp beads LED3, and the warm white light lamp beads LED4 are arranged alternately. The positive electrode of the positive white light lamp bead LED1, the negative electrode of the warm white light lamp bead LED2, the positive electrode of the positive white light lamp bead LED3, and the negative electrode of the warm white light lamp bead LED4 are connected to the first wire 21. The negative electrode of the positive white light lamp bead LED1, the positive electrode of the warm white light lamp bead LED2, the negative electrode of the positive white light lamp bead LED3, and the positive electrode of the warm white light lamp bead LED4 are connected to the second wire 22 through the resistor R1. The working voltage of the positive white light lamp beads LED1, the warm white light lamp beads LED2, the positive white light lamp beads LED3, and the warm white light lamp beads LED4 is 9V.
[0037] Of course, as the third embodiment of the present utility model, a 4-parallel and 3-series method can also be adopted to form an LED lamp group 30, that is, an LED lamp group 30 includes 3 series-connected partitions. Each partition includes 4 parallel-connected LED lamp beads and 1 resistor, and the 4 LED lamp beads include 2 alternately arranged positive white light lamp beads and warm white light lamp beads. The external power supply is set to DC 24V, and the working voltage of the positive white light lamp beads and the warm white light lamp beads is 3V.
[0038] In one embodiment, a first dam 41 and a second dam 42 extending along the length direction of the substrate 10 are provided on the substrate 10. The first dam 41 and the second dam 42 are arranged oppositely to form a packaging groove 43 for accommodating the LED lamp group 30. It also includes a sealant 50 provided in the packaging groove 43 and covering the LED lamp group 30. After arranging the circuits, assembling the LED lamp beads and resistors on the substrate 10, the first dam 41 and the second dam 42 are established on the substrate 10 to form the packaging groove 43, so that the LED lamp beads and resistors are located in the packaging groove 43. Finally, the sealant 50 is injected into the packaging groove 43 to form a protective layer. Among them, the protective layer also has the effect of light emission. Further, the first dam 41 and the second dam 42 are made of light-impermeable materials, and the sealant 50 is made of light-transmitting materials. More preferably, the sealant 50 is set as a fluorescent glue. It can make the light emitted by the LED lamp beads be better concentrated and irradiated out from the light-emitting side of the sealant 50, having a better light-emitting effect.

Those skilled in the art can make equivalent deformations or replacements without departing from the spirit of the present utility model, and these equivalent deformations and replacements are all included in the scope defined by the claims of this application.
