Description

Technical Field

[0001] The utility model relates to the technical field of LED light strips, in particular to a side-entry type LED light strip device and a display panel. Background Art

[0002] The LED light strip is the light-emitting source of the backlight of an LED TV. The existing LED light strips are divided into direct-lit type and side-entry type according to the thickness of the LED TV. Among them, the side-entry type LED light strip consists of a lamp board, a plurality of LED lamp beads, a plurality of pads, and terminals. The pads play a supporting role to prevent abnormal conditions caused by collision with the LED lamp beads during customer assembly.

[0003] The existing pad structure is that the entire board surface is copper-clad, and the copper-clad surface is welded to the lamp board, and it cannot cause abnormal open or short circuits. Due to the small area of the side-entry type light strip and the large number of LED lamp beads, most of the space cannot be used to place pads, which easily causes abnormal open or short circuits. However, without pads, it is easy to squeeze the LED lamp beads during assembly, posing a relatively high usage risk. Summary of the Utility Model

[0004] In view of the above situation, it is necessary to provide a side-entry type LED light strip device and a display panel for the problem that the side-entry type LED light strip in the prior art is prone to squeezing the LED lamp beads during installation.

[0005] A side-entry type LED light strip device includes a side-entry type LED light strip and a plurality of pad assemblies. The side-entry type LED light strip includes a plurality of LED first lamp beads and a PCB board. The PCB board is provided with a plurality of positive electrode pads and a plurality of negative electrode pads. The LED first lamp beads are electrically connected to the positive electrode pads and the negative electrode pads. The pad assembly includes a pad body and a light-transmitting cover plate. The pad body is arranged between two adjacent LED first lamp beads and is welded to the PCB board. The pad body is recessed to form a first accommodation cavity. The light-transmitting cover plate is used to cover the first accommodation cavity. The first accommodation cavity is used to accommodate LED second lamp beads. The first accommodation cavity is provided with a first pad and a second pad. The first pad is electrically connected to the positive electrode pad and the LED second lamp bead respectively. The second pad is connected to the negative electrode pad and the LED second lamp bead respectively. The height of the pad body is the same as the height of the LED first lamp bead.

[0006] In this utility model, a spacer body is arranged between two adjacent first LED lamp beads. The height of the spacer body is the same as that of the first LED lamp beads. During installation, the side-entry type LED light strip is made to be nearly in contact with the edge of the adjacent light guide plate, so as to prevent the first LED lamp beads on the side-entry type LED light strip from being squeezed by the light guide plate. And a second LED lamp bead is arranged in the first accommodation cavity. The light of the second LED lamp bead passes through the light-transmitting cover plate, so that the spacer body also emits light. This not only facilitates installation but also makes up for the light shielding and loss caused by adding a spacer component on the PCB board.

[0007] Further, the spacer body is a cuboid or a cylinder.

[0008] Further, the light-transmitting cover plate is rectangular or circular.

[0009] Further, a plurality of first magnetic attraction blocks are arranged at the bottom of the light-transmitting cover plate, and a plurality of second magnetic attraction blocks are arranged at the top of the spacer body. The first magnetic attraction blocks are adapted to the second magnetic attraction blocks.

[0010] Further, third solder pads are arranged on both sides of the bottom of the spacer body.

[0011] In this utility model, third solder pads are arranged on both sides of the bottom of the spacer body to prevent the PCB board from short-circuiting or opening.

[0012] Further, the spacer body is a glass fiber epoxy copper clad laminate or poly(1,4-cyclohexanedimethylene terephthalate), and the light-transmitting cover plate is a transparent plate.

[0013] This utility model also provides a display panel, which includes the side-entry type LED light strip device and the light guide plate as described above. The light guide plate is provided with a plurality of bumps, and the positions of the bumps correspond to those of the spacer body.

[0014] In this utility model, through the corresponding arrangement of the bumps and the spacer body, during installation, a gap is further formed between the side-entry type LED light strip and the edge of the adjacent light guide plate on one side, so as to prevent the side-entry type LED light strip from squeezing the first LED lamp beads.

The spacer body 201 is disposed adjacent to two of the first LED beads 110 and is welded to the PCB board 100. The spacer body 201 is recessed to form a first accommodation cavity 211. The light - transmissive cover plate 202 is used to cover the first accommodation cavity 211. The first accommodation cavity 211 is used to accommodate a second LED bead 212. The first accommodation cavity 211 is provided with a first pad (not shown) and a second pad (not shown) at intervals. The first pad is electrically connected to the positive pad 101 and the second LED bead 212 respectively. The second pad is connected to the negative pad 102 and the second LED bead 212 respectively. The height of the spacer body 201 is the same as the height of the first LED bead 110. Third pads (not shown) are provided on both sides of the bottom of the spacer body 201. A plurality of first magnetic attraction blocks 221 are provided at the bottom of the light - transmissive cover plate 202, and a plurality of second magnetic attraction blocks 213 are provided at the top of the spacer body 201. The first magnetic attraction blocks 221 are adapted to the second magnetic attraction blocks 213.

[0023] Specifically, the spacer body 201 is a glass - fiber epoxy copper - clad laminate or poly(1,4 - cyclohexanedimethylene terephthalate), and the light - transmissive cover plate 202 is a transparent sheet.

[0024] The present utility model further provides a display panel 3, as Figures 1 to 3 shown.
