Description

Technical Field

[0001] The utility model relates to the technical field of plastic steel belt winding, in particular to an LED packaging bracket. Background Art

[0002] In recent years, the application of LED lamps has developed rapidly, and the scope of use has become more and more extensive. The LED bracket is the base of the LED lamp bead before packaging. On the basis of the LED bracket, the chip is fixed in, the positive and negative electrodes are welded, and then the packaging glue is used to encapsulate the LED bracket once. The formed LED bracket generally includes a bracket body, a first metal pole piece and a second metal pole piece, which are usually made of plastic and metal;

[0003] The existing patent discloses a CN214753829U plastic steel belt winding machine. By setting a layer of heat-conducting base layer under the mounting part where the LED chip is placed, the heat-conducting base layer can conduct the heat as a whole and transfer it to the bottom plate of the bracket. By setting evenly distributed concave points on the bottom plate of the bracket, the heat-conducting area and the heat-dissipating area can be increased. Insulating strips are set at the contact positions of the positive and negative electrodes and the bottom plate of the bracket to increase insulation. A protective layer is set at the edge to increase waterproofness and reduce aging of the insulating strips. The setting of the arc-shaped reflective surface can increase the reflective effect of the lamp beads.

[0004] However, in this patent, the heat conduction area is only increased by evenly distributed concave points, which cannot effectively dissipate the heat of the heat-conducting base layer. Therefore, during use, the heat dissipation effect of the heat-conducting base layer is not ideal, which still affects the heat dissipation effect of the lamp beads and causes damage to the lamp beads.

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to provide an LED packaging bracket.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: an LED packaging bracket, comprising a bracket seat, and a bracket bottom plate is arranged at the bottom of the bracket seat;

[0007] A heat conducting sheet is embedded and installed at the bottom of the bracket seat, a heat sink is embedded and installed on the bracket bottom plate below the heat conducting sheet, a second heat dissipation hole is opened on the top of the heat dissipation plate, a first heat dissipation hole is opened on the outer wall of the heat dissipation plate, and the first heat dissipation hole is connected with the second heat dissipation hole.

[0008] As a preferred embodiment, arc grooves are opened at the four corners of the bottom plate of the bracket, a rotating rod is arranged on the arc groove, a welding plate is rotatably connected to the rotating rod, the arc groove and the welding plate are both arc structures, and the diameter of the welding plate is smaller than the diameter of the arc groove.

[0011] The beneficial effect of adopting the above further solution is that when the first ventilation hole is connected to the first heat dissipation hole, the heat on the heat conductive sheet can be dissipated through the first ventilation hole and the first heat dissipation hole, so that the temperature of the heat conductive sheet is reduced and the heat dissipation effect is accelerated.

[0012] As a preferred embodiment, a snap-in plate is inserted into the snap-in slot, a snap-in block is provided on one side of the snap-in plate located on the bottom plate of the bracket, the snap-in block is slidably connected to the snap-in slot, a second ventilation hole is provided on the snap-in plate, the second ventilation hole is connected to the first ventilation hole, a socket is provided at the bottom of the snap-in plate, and there are three sockets in total, and the three sockets are on the same horizontal line.

When in use, it can be installed by welding or plug-in method as needed, thereby increasing the installation methods.

[0016] As a preferred implementation, a reflection cavity is provided in the support seat, and the longitudinal cross-section of the reflection cavity is a trapezoid that is larger at the top and smaller at the bottom.

[0017] The beneficial effect of adopting the above further solution is that under the action of the reflection cavity, the light emitted by the LED chip forms a mirror reflection, thereby improving the mirror reflection intensity of the light, and the brightness is higher than the diffuse reflection in the prior art.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] 1. The utility model absorbs the heat at the bottom of the lamp bead through the heat conductive sheet. At this time, under the action of the heat dissipation plate, the heat on the heat conductive sheet is discharged to the outside of the bracket bottom plate for heat exchange under the action of the first heat dissipation hole and the second heat dissipation hole, so that the temperature on the bracket seat is reduced. Further, under the action of the heat conductive sheet, the bottom plate of the bracket seat is a sealed structure, which can effectively prevent external water vapor from slowly penetrating into the lamp bead through the gap of the packaging bracket, causing the fluorescent powder in the fluorescent glue to agglomerate, and the colloid is prone to cracking and peeling, resulting in dead lamps. Therefore, the temperature resistance of the device during use is improved.

[0020] 2. In the utility model, the device has two installation methods of plug-in and welding. During the installation process, the welding plate can be rotated out as needed.

At this time, the plug-in installation method can be realized through the plug-in seat. Compared with the traditional installation method, the device improves the diversity of installation.
