[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0028] like Figures 1 to 5 As shown, an embodiment of the utility model provides an LED lamp board, which includes a board body 10, multiple LED lamp beads 20, and multiple components 30. The board body 10 includes a cutting area 11 and a component area 12; an array of multiple LED lamp beads 20 is arranged on the front side of the board body 10, and multiple LED lamp beads 20 are arranged in the cutting area 11 and the component area 12; multiple components 30 are all arranged on the rear side of the board body 10, each LED lamp bead 20 is electrically connected to the corresponding component 30, and multiple components 30 are all arranged in the component area 12.
[0029] By applying the technical solution of the utility model, the LED light board includes a board body 10, a plurality of LED lamp beads 20 and a plurality of components 30. Since each LED lamp bead 20 is electrically connected to the corresponding component 30, the plurality of components 30 can provide power and control signals to the LED lamp beads 20, so that the plurality of LED lamp beads 20 can display the required pattern. At the same time, since the plurality of components 30 are arranged in the component area 12, when the LED light board is cut according to the actual environment, the component area 12 will not affect the cutting area 11, and it can be achieved by cutting the cutting area 11. Compared with the solution in the related art in which the components 30 are evenly distributed on the board body 10, by arranging the plurality of components 30 in the component area 12, the area of the cutting area 11 can be increased, so that the operator can obtain a larger cutting area 11, so that the requirements can be met after the LED light board is cut. And there is no need to rearrange the circuit board, which reduces the cost and saves the development time.
[0030] It should be noted that the board body 10 is only divided into a cutting area 11 and a component area 12 , and the cutting area 11 and the component area 12 do not overlap each other.
[0031] Specifically, LED is the abbreviation of light emitting diode, a commonly used light emitting device that emits light by releasing energy through the combination of electrons and holes, and then converts electrical energy into light energy. It is widely used in the field of lighting.
[0032] The LED lamp bead 20 is a common light emitting diode, which can be a three-color lamp bead or a lamp bead of other colors.
[0033] In this embodiment, since each LED lamp bead 20 is electrically connected to the corresponding component 30, the cutting area 11 can be formed into different shapes during cutting, and the cut portion will not affect the luminous effect of the uncut portion of the LED lamp bead 20. Therefore, the user can cut the cutting area 11 according to actual needs without having to consider the problem that the LED lamp bead 20 cannot emit light.
[0034] like Figure 1 and Figure 4 As shown, the cutting area 11 and the component area 12 are sequentially arranged in the length direction of the board body 10. The above arrangement has the advantages of simple structure and convenient processing.
[0035] In other embodiments, the cutting area 11 and the component area 12 may be arranged in the width direction of the board 10. Of course, the component area 12 may also be arranged at the corner of the board 10. Alternatively, according to actual needs, the component area 12 may be arranged in the middle of the cutting area 11. As long as the area of the cutting area 11 can be increased and the component area 12 does not affect the cutting of the cutting area 11, it will be fine.
[0036] In this embodiment, the component area 12 is located at one end of the board body 10. The above arrangement has the advantages of simple structure and easy processing.
[0037] like Figure 1 and Figure 2 As shown, the plurality of components 30 include a connector 31 and an IC chip 32, and the connector 31 and the IC chip 32 are electrically connected to the LED lamp bead 20 respectively. The connector 31 can realize the electrical connection between external electrical components, such as a power supply and a control box, and the board body 10 to provide power and control signals to the LED lamp bead 20, and the IC chip 32 can perform image processing on the LED lamp bead 20.
[0038] The plurality of components 30 may further include capacitors. All components that affect the cutting area 11 are disposed in the component area 12 .
[0039] It should be noted that the IC chip 32 is a chip formed by manufacturing an integrated circuit formed by a large number of microelectronic components, such as transistors, resistors, capacitors, etc., on a substrate. Based on the electronic properties of semiconductor materials, a faulty circuit system is formed inside to realize the transition of electrons between different energy levels.
[0040] like Figure 2 As shown, the connector 31 includes a control socket 311 and a power socket 312, and the control socket 311 and the power socket 312 are respectively electrically connected to the LED lamp bead 20. The control socket 311 can transmit signals to the LED lamp bead 20, and the power socket 312 can transmit electric energy to the LED lamp bead 20.
[0041] In this embodiment, an external control signal can be transmitted to the LED light board through the control socket 311, and the control signal controls the IC chip to process the image, so that multiple LED lamp beads 20 can work together to present a graphics that meets the requirements.
[0042] like Figure 1 and Figure 2 As shown, there are multiple IC chips 32, and each LED lamp bead 20 is electrically connected to a corresponding IC chip 32. By providing multiple IC chips 32, image processing can be performed on multiple LED lamp beads 20, so that the LED light board can be provided with more LED lamp beads 20, thereby increasing the area of the LED light board.
[0043] In this embodiment, in order to facilitate the connection between the LED lamp beads 20 and the IC chip 32, the IC chip 32 is arranged in an array in the component area 12.
[0044] like Figure 2As shown, the control socket 311 and the power socket 312 are arranged at intervals along the length direction of the board body 10, and in the width direction of the board body 10, a plurality of IC chips 32 are arranged in an array on both sides of the control socket 311 and the power socket 312. The above arrangement has the advantages of simple structure and convenient connection.
[0045] In this embodiment, the control socket 311 is arranged near the end of the board body 10, and the power socket 312 is arranged inside the control socket 311. The extension direction of the control socket 311 and the extension direction of the power socket 312 both extend along the length direction of the board body 10, which can leave sufficient space for the IC chip 32.
[0046] In the width direction of the board body 10 , four IC chips 32 are arranged on both sides of the control socket 311 and the power socket 312 , and the IC chips 32 on each side are arranged in an array.
[0047] It should be noted that the plurality of components 30 are not limited to the above arrangement, as long as they can be arranged in the component area 12 and connected to the LED lamp beads 20 .
[0048] In this embodiment, the board body 10 is a flexible circuit board. The use of a flexible circuit board can facilitate cutting of the board body 10 and make the cross section after cutting more uniform.

[0051] The thickness of the plate body 10 may be 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, or any value less than 0.6 mm.
[0052] like Figure 1 As shown, a plurality of magnets 13 that can magnetically cooperate with the box are arranged on the rear side of the board 10, and magnets 13 are arranged in the cutting area 11 and the component area 12. The magnetic force between the magnets 13 and the box is utilized to further adsorb the board 10 on the front side of the box, and at the same time, the board 10 can be easily removed from the box.
[0053] In this embodiment, in order to make the connection between the LED light board and the box body more stable, connecting screws may be provided to prevent the LED light board from falling off the box body due to unexpected circumstances.
[0054] In this embodiment, magnets 13 are provided in both the cutting area 11 and the component area 12. In the cutting area 11, the magnets 13 are arranged in an array, with 5 magnets arranged in each column and 7 magnets arranged in each row.

At the same time, since the plurality of components 30 are all arranged in the component area 12, when the LED light board is cut according to the actual environment, the component area 12 will not affect the cutting area 11, and it can be achieved by cutting the cutting area 11. Compared with the solution in the related art that the components 30 are evenly distributed on the board body 10, by arranging the plurality of components 30 in the component area 12, the area of the cutting area 11 can be increased, so that the operator can obtain a larger cutting area 11, so that the requirements can be met after the LED light board is cut. There is no need to rearrange the circuit board, which reduces costs and saves development time.
