[0026] For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Please refer to Figure 1-2 A light source bracket of a COB light source module structure in a preferred embodiment of the present invention comprises a first bracket 3 for connecting a COB light source 1 and a second bracket 4 for connecting a heat sink 2, wherein a first magnet 31 and a first circuit shrapnel 32 are provided on the first bracket 3, and a second magnet 41 corresponding to the first magnet 31 and a second circuit shrapnel 42 corresponding to the first circuit shrapnel 32 are provided on the second bracket 4, wherein the first magnet 31 and the second magnet 41 are attracted to each other, and when the first bracket 3 and the second bracket 4 are connected by attraction, the first circuit shrapnel 32 and the second circuit shrapnel 42 are in contact. The first magnet 31 and the second magnet 41 attract each other, and can guide the first bracket 3 to rotate relative to the second bracket 4 until the first magnet 31 and the second magnet 41 are facing each other, and relative rotation does not occur between the first bracket 3 and the second bracket 4, thereby correcting the position of the first bracket 3, ensuring that when the first magnet 31 and the second magnet 41 are facing each other, the first circuit shrapnel 32 and the second circuit shrapnel 42 can contact each other, ensuring that the circuit is closed, and can supply power. Through such a structure, the connection between the first bracket 3 and the second bracket 4 can be achieved without setting a thread as in the prior art, and the first bracket 3 can be guided to rotate relative to the second bracket 4. The first bracket 3 can automatically rotate to the correct position, and the operation is simple. Therefore, the light source can be installed or replaced more quickly, thereby improving the work efficiency of installing or replacing the light source.

[0028] The first bracket 3 is also provided with a third magnet 33 having a polarity opposite to that of the first magnet 31, and the second bracket 4 is also provided with a fourth magnet 43 corresponding to the third magnet 33, and the third magnet 33 and the fourth magnet 43 attract each other. The third magnet 33 and the fourth magnet 43 can further assist the first bracket 3 to rotate relative to the second bracket 4. The polarities of the first magnet 31 and the third magnet 33 are opposite, which can prevent the first magnet 31 and the fourth magnet 43 from attracting each other, thereby ensuring that the first circuit shrapnel 32 and the second circuit shrapnel 42 can contact each other. When the first magnet 31 and the second magnet 41 attract each other, and the third magnet 33 and the fourth magnet 43 attract each other, the first bracket 3 is rotated so that the first magnet 31 corresponds to the fourth magnet 43, and at this time, there is a repulsive force between the first magnet 31 and the fourth magnet 43, and there is a repulsive force between the second magnet 41 and the third magnet 33, thereby popping out to the first bracket 3, and the first bracket 3 and the second bracket 4 are separated. With such a structure, the operation of removing the first bracket 3 from the second bracket 4 is also relatively simple, which improves the efficiency of replacing the light source. The first magnet 31 and the third magnet 33 are symmetrical about the center of the first mounting portion 34. This arrangement facilitates the first bracket 3 to be corrected to the correct position and is also convenient for the user to operate.

[0029] In this embodiment, the first magnet 31 and the third magnet 33 are inlaid on the first bracket 3. The second magnet 41 and the fourth magnet 43 are inlaid on the second bracket 4. In this way, the first magnet 31, the second magnet 41, the third magnet 33 and the fourth magnet 43 will not occupy the space between the first bracket 3 and the second bracket 4, saving space resources. The first bracket 3 is provided with a third mounting portion for mounting the first circuit shrapnel 32, and the second bracket 4 is provided with a fourth mounting portion for mounting the second circuit shrapnel 42. The third mounting portion and the fourth mounting portion can be set as grooves, and the third mounting portion and the fourth mounting portion can be placed in their respective corresponding grooves, saving space resources.

[0030] Please refer to Figure 2 The first bracket 3 is provided with a first mounting portion 34 for mounting the COB light source 1. When the first bracket 3 is connected to the second bracket 4 and the COB power source is mounted on the first mounting portion 34, the COB power source can fit with the heat sink 2 mounted on the second bracket 4, and the heat sink 2 can dissipate heat for the COB power source.

[0031] The light source bracket of this embodiment also includes an outer ring 5 arranged on the second bracket 4, the outer ring 5 is sleeved on the outside of the bracket, a first limit block 51 is arranged on the inner wall of the outer ring 5, and the first limit block 51 is arranged along the axial direction of the outer ring 5. A clamping block 35 is arranged on the first bracket 3. When the first bracket 3 and the second bracket 4 are connected by attraction, the first limit block 51 contacts and limits the clamping block 35. The first limit block 51 is arranged, and when the first bracket 3 is corrected to the correct position, the first limit block 51 can limit the first bracket 3 from rotating. The outer ring 5 and the second bracket 4 can also be arranged to be rotatably connected. In this way, when the outer ring 5 is rotated, the first limit block 51 drives the clamping block 35 and thus drives the first bracket 3 to rotate equivalent to the second bracket 4, which is convenient for the user to separate the first bracket 3 and the second bracket 4. A second stopper 52 is also provided on the inner wall of the outer ring 5. The second stopper 52 is provided along the circumferential direction of the outer ring 5. The second stopper 52 is provided on the side of the first bracket 3 away from the second bracket 4. The first stopper 51 is provided at one end of the second stopper 52. The first stopper 51 and the second stopper 52 together form a slot that matches the stopper 35. By providing the second stopper 52, when the first magnet 31 and the second magnet 41 lose magnetism and the third magnet 33 and the fourth magnet 43 also lose magnetism, the second stopper 52 can block the stopper 35 to prevent the first bracket 3 from falling off the second bracket 4.

[0032] This embodiment also provides a COB light source module structure, including the above-mentioned light source bracket.

[0033] The working process of the present invention is as follows: when it is necessary to separate the first bracket 3 and the second bracket 4, the first bracket 3 is rotated, the card block 35 leaves the card slot, the first magnet 31 and the fourth magnet 43 gradually approach the repulsive force to increase, the second magnet 41 and the third magnet 33 gradually approach the repulsive force to increase, and the first bracket 3 is ejected. When it is necessary to connect the first bracket 3 and the second bracket 4, the first bracket 3 is placed on the second bracket 4, there is an attractive force between the first magnet 31 and the second magnet 41, and there is also an attractive force between the third magnet 33 and the fourth magnet 43, the first bracket 3 is guided to rotate to the correct position, the first circuit shrapnel 32 and the second circuit shrapnel 42 are in contact, and the card block 35 enters the card slot.

[0034] In summary, the embodiment of the present invention provides a COB light source module structure and a light source bracket thereof, wherein the light source bracket can install or replace the light source more quickly by providing the first magnet 31 and the second magnet 32, thereby improving the work efficiency of installing or replacing the light source.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
