[0002] LED bracket refers to the base of LED lamp bead before packaging. On the basis of LED bracket, the chip is fixed in, positive and negative electrodes are welded, and then the packaging glue is used to package it once. LED bracket is generally made of copper material. (There are also iron, aluminum and ceramic materials, etc.). The bracket is equipped with corresponding solid crystal area and wire welding area. By fixing the corresponding chip in the solid crystal area, and then connecting the corresponding electrodes inside the LED lamp bead through welding gold wire, the LED lamp bead can be removed from the bracket after packaging. The copper feet at both ends of the lamp bead become the positive and negative electrodes of the lamp bead, which are used to weld to LED lamps or other LED finished products.

[0022] See also Figures 1 to 3 In an embodiment of the present invention, a novel six-in-one medium-to-high power LED bracket with thermal and electrical separation includes: an insulating body 1 made of plastic material and a plurality of conductive terminals 3 embedded in the insulating body 1; the surface of the insulating body 1 is concave inward and is provided with a group of reflective cups 4;

[0023] Each group of conductive terminals 3 has a wire pad 32 and a conductive foot 31. The wire pad 32 of the conductive terminal 3 is exposed at the bottom of the reflective cup 4 and is used to connect with the pins of the lamp bead chip; and the conductive foot 31 of the conductive terminal 3 is exposed outside the insulating body 1 and is used to connect with an external power source.

[0024] The reflective cup 4 is also provided with a group of metal pads 2 for arranging lamp beads. Each group of lamp beads (including but not limited to: red, green, blue, purple and yellow lamp beads) is fixedly soldered on the metal pads 2, and the pins of the lamp beads are connected to the corresponding conductive terminals 3 through gold wires; and at least one group of circular concave cups 21 are stamped on the metal pads 2. After the blue light chip is fixedly soldered in the circular concave cups 21, the fluorescent powder is filled to achieve the effect of white light color temperature, and the six color temperature luminous effects of the LED bracket are achieved;

[0025] The lower end of the hardware pad 2 is the heat dissipation surface 22, which is exposed to the bottom position of the insulating body 1; the heat generated by the operation of the lamp bead chip will be discharged from the heat dissipation surface 22, thereby realizing the thermal and electrical separation structure of the lamp bead chip, achieving high thermal conductivity and fast heat dissipation effects, and meeting the high-power use requirements of LEDs.

[0027] Furthermore, in order to improve the structural stability of the hardware pad 2 on the insulating body 1, the hardware pad 2 is integrally formed with a group of conductive terminals 3; this can not only improve the structural tightness of the hardware pad 2 and the insulating body 1, but also enable the lamp bead chip connected to the group of conductive terminals 3 to be connected to the group of conductive terminals 3 by directly connecting the pins to the hardware pad 2, thereby reducing processing costs and improving production efficiency.

[0028] Furthermore, the number of conductive terminals 3 embedded in the insulating body 1 is at least 12 groups, so that at least six groups of lamp beads chips that can emit red, green, blue, purple, yellow and white warm light can be arranged in the hardware pad 2.

[0029] Preferably, the metal pad 2 is arranged at the center of the reflective cup 4, and each group of conductive terminals 3 is distributed on both sides of the metal pad 2 according to the distinction between positive and negative electrodes, so as to facilitate the connection between the lamp bead chip and the corresponding conductive terminal 3.

[0030] Preferably, C-angle marks 5 for distinguishing the positive and negative poles of each group of conductive terminals 3 are provided at the corners of the insulating body 1 .

[0031] It should also be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "including a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
