Abstract
Description
Technical Field
[0001] This application relates to the field of LED displays, and more particularly to an LED display light strip. Background Technology
[0002] LED light strips are widely used in decorative lighting scenarios such as shopping malls, hotels, and restaurants because of their high design flexibility. Multiple light strips can be flexibly combined to form an LED display screen, and they can be expanded according to different installation requirements.
[0003] In existing technologies, to improve display quality and achieve higher pixel density, the spacing between LED strips is typically reduced. This necessitates a corresponding reduction in the size of the LED strips and their internal circuit boards. However, this reduction limits the wiring space for the power supply lines, thus restricting their current-carrying capacity and resulting in reduced luminous intensity at the far end of the display. Furthermore, to achieve larger LED displays, the length of the LED strips needs to be increased accordingly; excessively long lines can also lead to voltage attenuation, causing uneven color and brightness. Utility Model Content
[0004] Based on this, this application discloses an LED display light strip, comprising a housing, wherein the housing further comprises:
[0005] A circuit board and a conductive strip for power supply, wherein multiple via groups are regularly arranged on the circuit board;
[0006] The circuit board has LED light emitters on both sides adjacent to the via group;
[0007] The conductive strip has multiple protrusions integrally and regularly arranged on the front side. The conductive strip is disposed on the back side of the circuit board, and the protrusions are embedded upward into the via group.
[0008] In one possible implementation, the conductive strip includes a first conductive strip and a second conductive strip, the via group includes a first via and a second via, and the protrusion includes a first protrusion and a second protrusion.
[0009] The first conductive strip and the second conductive strip are respectively provided with a plurality of first protrusions and second protrusions on their front sides in a regular manner. The first conductive strip and the second conductive strip are disposed on the back side of the circuit board. The first protrusions and the second protrusions are respectively embedded upward into the first through hole and the second through hole.
[0010] In one possible implementation, the circuit board further includes a first branch and a second branch, the first ends of the first branch and the second branch being electrically connected to a first protrusion and a second protrusion embedded in the first via and the second via, respectively, and the second ends being electrically connected to an LED light emitter adjacent to the first via and the second via.
[0011] In one possible implementation, at least one LED emitter is provided between every two adjacent via groups.
[0012] In one possible implementation, an adhesive filling layer is further provided inside the housing, which seals the circuit board, the first conductive strip, and the second conductive strip within the housing.
[0013] In one possible implementation, the light-emitting surface of the LED emitter exposes the encapsulation filling layer.
[0014] In one possible implementation, an insulating portion is provided between the circuit board and the housing, the insulating portion being used to isolate the first conductive strip from the second conductive strip, and between the first conductive strip, the second conductive strip and the housing.
[0015] In one possible implementation, the circuit board also includes signal lines that are electrically connected to the LED light source.
[0016] In one possible implementation, the circuit board is a rigid substrate.
[0017] In this application, the first and second conductive strips used for power supply are arranged on the back of the circuit board, rather than the power supply lines being arranged inside the circuit board. This allows the cross-sectional dimensions of the first and second conductive strips to be no longer limited by the size of the circuit board. This enables the cross-sectional dimensions of the conductive strips to be adjusted as needed to meet the demands of excessive current, thereby preventing voltage attenuation in the distant LED emitters and ensuring color consistency of the LED display strips. Furthermore, this application achieves electrical connection to the circuit board by providing first and second protrusions on the first and second conductive strips and embedding these protrusions into vias in the circuit board.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0028] As mentioned in the background section, in existing technologies, to improve display quality and achieve higher pixel density, the spacing between LED strips is typically reduced. When the spacing between LED strips is reduced to a certain extent, the dimensions of the LED strips and their internal circuit board 1 also need to be reduced accordingly to further reduce the distance between LED beads. However, this reduction limits the wiring space of the power supply lines, thereby limiting the current carrying capacity of the lines and causing a decrease in the luminous intensity of the distant LEDs, resulting in uneven color and brightness. Moreover, to achieve longer LED displays, the length of the LED strips also needs to be increased, and excessively long lines also lead to voltage attenuation.
[0029] In view of this, this application discloses an LED display light strip that can realize power supply at the far end of the light strip.
[0030] The LED display strip includes a housing 5, characterized in that the housing 5 further comprises: a circuit board 1 and a conductive strip for power supply; the circuit board has a plurality of via groups 10 arranged in a regular pattern; LED light emitters 4 are arranged on both sides adjacent to the via groups 10; the conductive strip has a plurality of protrusions integrally and regularly arranged on the front side, and the conductive strip is disposed on the back side of the circuit board 1, with the protrusions embedded upward into the via groups 10. Preferably, the circuit board 1 is a rigid material.
[0031] Among them, such as Figure 2 As shown, the housing 5 can be a U-shaped housing.
[0032] Furthermore, the conductive strip includes a first conductive strip 2 and a second conductive strip 3, the via group includes a first via 11 and a second via 12, and the protrusion includes a first protrusion 123 and a second protrusion 124.
[0033] like Figure 6 , Figure 7 As shown, the LED display light strip includes a housing 5, a circuit board 1, a first conductive strip 2, and a second conductive strip 3, all of which are disposed inside the housing 5. An LED light emitter 4 is also disposed on the circuit board. The light-emitting surface of the LED light emitter 4 on the circuit board 1 is aligned with the opening direction of the housing 5. The first conductive strip 2 and the second conductive strip 3 are used to supply power to the LED light emitter 4.
[0034] like Figure 1 As shown, the circuit board 1 has multiple via groups 10 arranged in a regular pattern. The circuit board 1 is located at the via groups 10 ( Figure 1 The via group 10 is marked with a dashed line. LED light emitters 4 are provided on both adjacent sides. The via group 10 includes a first via 11 and a second via 12. (See image below.) Figure 3 As shown, the front sides of the first conductive strip 2 and the second conductive strip 3 are respectively provided with a plurality of first protrusions 123 and second protrusions 124 in an integral and regular manner. The first conductive strip 2 and the second conductive strip 3 are provided on the back side of the circuit board 1. The first protrusions 123 and the second protrusions 124 are respectively embedded upward into the first through hole 11 and the second through hole 12.
[0035] In this embodiment, the first conductive strip 2 and the second conductive strip 3 are electrically connected to the circuit board 1 by embedding the first protrusion 123 and the second protrusion 124 into the first through hole 11 and the second through hole 12 on the circuit board, respectively.
[0036] In this embodiment, the first conductive strip 2 and the second conductive strip 3 used for power supply are arranged on the back of the circuit board 1, instead of arranging the power supply lines inside the circuit board 1. This makes the cross-sectional dimensions of the first conductive strip 2 and the second conductive strip 3 no longer limited by the dimensions of the circuit board 1. This allows the cross-sectional dimensions of the conductive strips to be adjusted as needed to meet the requirements of excessive current, thereby avoiding voltage attenuation in the far-end LED light emitter and ensuring the color consistency of the LED display strips. Furthermore, this application achieves electrical connection with the circuit board 1 by providing a first protrusion and a second protrusion on the first conductive strip 2 and the second conductive strip 3, and embedding the first protrusion and the second protrusion into the via group 10 on the circuit board 1.
[0037] like Figure 4 , Figure 5As shown, the circuit board 1 also includes a first branch line 13 and a second branch line 14. The first ends of the first branch line 13 and the second branch line 14 are electrically connected to the first protrusion 123 and the second protrusion 124 embedded in the first via 11 and the second via 12, respectively. The second ends are electrically connected to the LED light emitters 4 adjacent to the first via 11 and the second via 12, respectively.
[0038] In this embodiment, the first ends of the first branch line 13 and the second branch line 14 are electrically connected to the first protrusion 123 and the second protrusion 124 through the first via 11 and the second via 12, respectively. The second ends of the first branch line 13 and the second branch line 14 are electrically connected to the LED light-emitting body 4 adjacent to the group of vias, so that the LED light-emitting body 4 is electrically connected to the first conductive strip 2 and the second conductive strip 3, thereby supplying power to the LED light-emitting body 4.
[0039] The first conductive strip 2 and the second conductive strip 3 are preferably made of copper, but other conductive materials such as aluminum, gold, silver, and iron can also be used. This application does not limit the materials used in this regard.
[0040] It should be pointed out that, such as Figure 1 As shown, the upper surface of the circuit board in this application may also include a signal line 8. In this case, the signal line is electrically connected to the LED light-emitting element disposed on the circuit board to realize signal transmission. Of course, the LED light strip in this application may not include a signal line. In this case, the signal is transmitted via the first conductive strip 2 and the second conductive strip 3 in a carrier wave manner.
[0041] At least one LED can be provided between every two adjacent via groups 10 on the circuit board. The LED provided between two adjacent via groups 10 can be electrically connected to the first protrusion 123 and the second protrusion 124 through the first branch line 13 and the second branch line 14 on the circuit board, and then electrically connected to the first conductive strip and the second conductive strip.
[0042] In some embodiments, such as Figure 4 As shown, an LED light source 4 is provided between every two adjacent via groups 10 on the circuit board 1. That is, a via group 10 is provided between every two adjacent LED light sources 4. At this time, for each LED light source 4, there are two first branch lines 13 electrically connected to it, which come from the first via 11 above and below it respectively. The second branch line 14 is the same, and will not be described in detail here.
[0043] In other embodiments, such as Figure 5As shown, two LEDs 4 are arranged between every two adjacent via groups 10 on the circuit board 1. In this embodiment, not every two adjacent LEDs 4 are connected by via groups 10, but are arranged at intervals. That is, for each LED 4, there is only one first branch line 13 electrically connected to it, which comes from the first via 11 above or below it. The second branch line 14 is the same, and will not be described in detail here.
[0044] In other embodiments, the first branch line 13 and the second branch line 14 are circuits inside the circuit board 1. The first branch line 13 and the second branch line 14 are disposed inside the circuit board 1 and extend into the first via 11 and the second via 12, respectively. When the first conductive strip 2 and the second conductive strip 3 are respectively embedded in the first via 11 and the second via 12 on the circuit board 1, the first branch line 13 and the second branch line 14 make electrical contact with the protrusions 123 of the first conductive strip 2 and the second conductive strip 3, thereby supplying power to the LED light source 4.
[0045] Furthermore, an adhesive filling layer 6 is provided inside the housing 5, which seals the circuit board 1, the first conductive strip 2, and the second conductive strip 3 inside the housing 5.
[0046] It is understandable, such as Figure 6 As shown, in order not to affect the light-emitting effect of the LED light-emitting body 4, the light-emitting surface of the LED light-emitting body 4 can be exposed to the encapsulation filling layer 6.
[0047] In some embodiments, such as Figure 6 As shown, the LED display light strip also includes an insulating part 7, which is disposed below the circuit board 1, between the first conductive strip 2 and the second conductive strip 3, and the front of the insulating part 7 contacts the lower surface of the circuit board 1, and the lower surface contacts the bottom of the housing 5.
[0048] In other embodiments, such as Figure 7 As shown, the insulating part 7 is disposed between the first conductive strip 2 and the bottom of the housing 5 and contacts the first conductive strip 2 and the U-shaped outer shell. The insulating part is also disposed between the second conductive strip 3 and the bottom of the housing 5 and contacts the second conductive strip 3 and the U-shaped outer shell 5.
[0049] It should be understood that the phrases "one embodiment" or "some embodiments" throughout the specification mean that a particular feature, structure, or characteristic related to an embodiment is included in at least one embodiment of this application. Therefore, "in one embodiment" or "in one embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.
[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
