Referring to fig. 1-2, a light source bracket of a COB light source module structure according to a preferred embodiment of the present invention includes a first bracket 3 for connecting a COB light source 1 and a second bracket 4 for connecting a heat sink 2, the first bracket 3 is provided with a first magnet 31 and a first circuit elastic sheet 32, the second bracket 4 is provided with a second magnet 41 corresponding to the first magnet 31 and a second circuit elastic sheet 42 corresponding to the first circuit elastic sheet 32, the first magnet 31 and the second magnet 41 attract each other, and when the first bracket 3 and the second bracket 4 are connected by attraction, the first circuit elastic sheet 32 and the second circuit elastic sheet 42 contact each other. The first magnet 31 and the second magnet 41 attract each other, and can guide the first support 3 to rotate relative to the second support 4 until the first magnet 31 and the second magnet 41 are right opposite, and the first support 3 and the second support 4 cannot rotate relatively, so that the position of the first support 3 is corrected, and when the first magnet 31 and the second magnet 41 are right opposite, the first circuit elastic sheet 32 and the second circuit elastic sheet 42 can be in contact, the circuit is ensured to be closed, and power can be supplied to a power supply. Through such structure, need not to set up the screw thread like prior art, alright realize first support 3 and the connection of second support 4, can guide first support 3 to rotate for second support 4 moreover, first support 3 can rotate to the exact position automatically, and is easy and simple to handle, installation or change light source that from this can be comparatively quick, improve the installation or change the work efficiency of light source.

The first bracket 3 is also provided with a third magnet 33 with the polarity opposite to that of the first magnet 31, 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 in rotating relative to the second bracket 4. The polarities of the first magnet 31 and the third magnet 33 are opposite, so that the first magnet 31 and the fourth magnet 43 can be prevented from attracting each other, and the first circuit elastic sheet 32 and the second circuit elastic sheet 42 can be ensured to be contacted. When the first magnet 31 and the second magnet 41 are attracted to each other and the third magnet 33 and the fourth magnet 43 are attracted to each other, the first bracket 3 is rotated so that the first magnet 31 corresponds to the fourth magnet 43, and at this time, a repulsive force exists between the first magnet 31 and the fourth magnet 43 and a repulsive force exists between the second magnet 41 and the third magnet 33, so that the first bracket 3 and the second bracket 4 are ejected to each other, and the separation is realized. With such a configuration, the operation of detaching the first holder 3 from the second holder 4 is also simplified, and the work efficiency of replacing the light source is improved. The first magnet 31 and the third magnet 33 are centrosymmetric with respect to the first mounting portion 34. This arrangement facilitates the first support 3 to be straightened to the correct position and also facilitates the handling by the user.

In the present embodiment, the first magnet 31 and the third magnet 33 are mounted on the first bracket 3. The second magnet 41 and the fourth magnet 43 are mounted on the second bracket 4. With the arrangement, the first magnet 31, the second magnet 41, the third magnet 33 and the fourth magnet 43 do not occupy the space between the first bracket 3 and the second bracket 4, thereby saving space resources. The first support 3 is provided with a third mounting part for mounting the first circuit elastic sheet 32, and the second support 4 is provided with a fourth mounting part for mounting the second circuit elastic sheet 42. The third installation part and the fourth installation part can be arranged into grooves, and the third installation part and the fourth installation part can be arranged in the corresponding grooves, so that space resources are saved.

Referring to fig. 2, the first bracket 3 is provided with a first mounting portion 34 for mounting the COB light source 1. When first support 3 is connected with second support 4, when the COB power is installed on first installation department 34, the COB power can laminate mutually with radiator 2 of installing on second support 4, and radiator 2 can be the COB power heat dissipation.

The light source support of this embodiment, still including setting up outer loop 5 on second support 4, the outside of support is located to outer loop 5 cover, is equipped with first stopper 51 on the inner wall of outer loop 5, and first stopper 51 sets up along the axial direction of outer loop 5, is equipped with fixture block 35 on first support 3, and when first support 3 and second support 4 were connected through the appeal, first stopper 51 contacted and spacing fixture block 35 with fixture block 35. The first limiting block 51 is arranged, and when the first support 3 is corrected to a correct position, the first limiting block 51 can limit the first support 3 to not rotate any more. The outer ring 5 and the second bracket 4 can be rotatably connected, so that when the outer ring 5 is rotated, the first limiting block 51 drives the clamping block 35 to drive the first bracket 3 to rotate, which is equivalent to the second bracket 4, and a user can separate the first bracket 3 from the second bracket 4 conveniently. Still be equipped with second stopper 52 on the inner wall of outer loop 5, second stopper 52 sets up along the circumferential direction of outer loop 5, and second stopper 52 sets up in the one side that first support 3 deviates from second support 4, and first stopper 51 sets up in the one end of second stopper 52, and first stopper 51 and second stopper 52 form the draw-in groove with fixture block 35 matched with jointly. By providing the second stopper 52, when the first magnet 31 and the second magnet 41 are de-magnetized and the third magnet 33 and the fourth magnet 43 are also de-magnetized, the second stopper 52 can block the latch 35, preventing the first bracket 3 from falling off the second bracket 4.

This embodiment still provides a COB light source module structure, includes foretell light source support.

The working process of the invention is as follows: when the first bracket 3 and the second bracket 4 need to be separated, the first bracket 3 is rotated, the clamping block 35 leaves the clamping groove, the repulsive force of the first magnet 31 and the fourth magnet 43 which are gradually close to each other is increased, the repulsive force of the second magnet 41 and the third magnet 33 which are gradually close to each other is increased, and the first bracket 3 is ejected. When the first bracket 3 and the second bracket 4 need to be connected, the first bracket 3 is placed on the second bracket 4, attraction force exists between the first magnet 31 and the second magnet 41, attraction force also exists 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 elastic sheet 32 is contacted with the second circuit elastic sheet 42, and the clamping block 35 enters the clamping groove.

In summary, the embodiment of the present invention provides a COB light source module structure and a light source bracket thereof, in which a first magnet 31 and a second magnet 32 are disposed on the light source bracket, so that a light source can be installed or replaced more quickly, and the work efficiency of installing or replacing the light source is improved.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
