[0027] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0028] Please refer to Figures 1 to 3 As shown, a quick-release downlight includes a fixed bracket 1 and a light source module 2. The fixed bracket 1 is provided with a hook 11, which has a hook head 111. The light source module 2 is provided with a guide groove 21, a locking groove 22, and a reset groove 23 to guide the sliding direction of the hook head 111. The guide groove 21 has a starting end and an ending end. The locking groove 22 communicates with the ending end of the guide groove 21. The setting height of the locking groove 22 is higher than the ending end of the guide groove 21 and lower than the starting end of the guide groove 21. The reset groove 23 has a reset end and a support end. At the connection end, the receiving end of the reset groove 23 is connected to the end of the lock groove 22 away from the guide groove 21, and the setting height of the receiving end of the reset groove 23 is lower than the end of the corresponding connected lock groove 22. The reset end of the reset groove 23 is connected to the beginning end of the guide groove 21. The groove depth of the reset groove 23 at least at the reset end gradually decreases, and the groove depth of the reset end of the reset groove 23 is less than the groove depth of the beginning end of the guide groove 21. When the hook head 111 is at least located at the end of the guide groove 21 and in the lock groove 22, it is subjected to a force in the direction of the reset groove 23.

[0029] Working principle: During the installation of the light source module 2, the hook 111 is positioned at the beginning of the guide groove 21. The light source module 2 is then pushed upwards so that the hook 111 moves toward the end of the guide groove 21. The guide groove 21 generates elastic potential energy between the hook 111 and the latch 11, and the hook 111 is subjected to a force toward the reset groove 23. At the same time, since the locking groove 22 is set at a height higher than the end of the guide groove 21, when the hook 111 enters the end of the guide groove 21, the hook 111 will immediately lock into the locking groove 22 under the action of elastic force. The hook 111 will also make a sound when it hits the side wall of the locking groove 22, thus prompting the assembly personnel that the hook 111 has entered the locking groove 22. Then the upward push of the light source module 2 can be removed, so that the light source module 2 can be hung on the hook, thereby completing the assembly of the light source module 2 on the fixed bracket 1.

[0030] During the disassembly of the light source module 2, since the receiving end of the reset groove 23 is set at a height lower than the locking groove 22, the light source module 2 is pushed upward to make the hook 111 exit the locking groove 22. At this time, the hook 111 will immediately enter the reset groove 23 under the action of the elastic force, and the hook 111 will hit the side wall of the reset groove 23 to produce a sound, thereby prompting the assembly personnel that the hook 111 has entered the reset groove 23, and then the light source module 2 can be removed from the fixed bracket 1.

[0031] During the installation of the light source module 2, in order to prevent the hook 111 from entering the reset groove 23, the groove depth of the reset end of the reset groove 23 is set to be less than the groove depth of the beginning end of the guide groove 21. This ensures that when the hook 111 is at the beginning end of the guide groove 21, the light source module 2 moves upward and the hook 111 can only move towards the end of the guide groove 21.

[0032] Please refer to Figure 1 and Figure 2 As shown, the fixed bracket 1 is further provided with a clearance opening 12 that is opposite to the reset groove 23.

[0033] As can be seen from the above description, the clearance opening 12 creates space so that the hook head 111 can protrude from the light source module 2 due to the reduced depth of the reset groove 23, thereby ensuring the smooth movement of the hook head 111 in the reset groove 23.

[0034] Please refer to Figures 1 to 3 As shown, the fixed bracket 1 is further provided with positioning ribs 13, and the light source module 2 is provided with notches 24 that are adapted to the positioning ribs 13.

[0035] As described above, during the installation of the light source module 2, inserting the positioning rib 13 into the notch 24 can complete the positioning between the fixed bracket 1 and the light source module 2, that is, allow the hook 111 to accurately enter the beginning of the guide groove 21.

[0036] Please refer to Figure 2 As shown, the hook 11 further includes a limiting part 112, and the fixing bracket 1 is provided with limiting ribs 14 that abut against both sides of the limiting part 112.

[0037] As can be seen from the above description, since the hook 111 enters the locking groove 22 and the reset groove 23 by means of elasticity, in order to ensure that the hook 111 has sufficient elasticity and the stability of the hook 11 on the fixed bracket 1 after each bounce of the hook 111, the fixed bracket 1 uses the limiting rib 14 to clamp the limiting part 112 of the hook 11.

[0038] Please refer to Figure 2 As shown, the hook 11 further has a fixing head 113, and the fixing bracket 1 is provided with a plug hole 15 for the fixing head 113 to be inserted.

[0039] As described above, the hook 11 is inserted into the insertion hole 15 of the fixed bracket 1 using the fixing head 113 to complete the installation of the hook 11 on the fixed bracket 1.

[0040] Please refer to Figure 2As shown, the hook 11 further includes a fixing part 114, and a fixing screw 16 is threaded onto the fixing bracket 1, with the nut of the fixing screw 16 abutting against the fixing part 114.

[0041] As can be seen from the above description, by using the fixing screw 16 to press the fixing part 114 onto the fixing bracket 1, the stability of the hook 11 on the fixing bracket 1 can be further improved.

[0042] Please refer to Figure 2 As shown, the preferred fixing part 114 is U-shaped, which can further increase the area where the fixing screw 16 presses against the fixing part 114.

[0043] Please refer to Figure 4 As shown, a buffer spring 3 is further provided between the light source module 2 and the fixed bracket 1.

[0044] As can be seen from the above description, during the process of pushing the light source module 2 into the fixed bracket 1, the buffer spring 3 is used to prevent rigid contact between the light source module 2 and the fixed bracket 1.

[0045] Please refer to Figure 3 and Figure 4 As shown, the buffer spring 3 is further provided with a buffer pad 31, which abuts against the fixed bracket 1.

[0046] As can be seen from the above description, the cushioning pad 31 is used to increase the cushioning area.

[0047] Please refer to Figure 2 As shown, the fixed bracket 1 is further provided with a buffer protrusion 17 facing the buffer spring 3.

[0048] As described above, the fixed bracket 1 contacts the buffer spring 3 or the buffer pad 31 through the buffer protrusion 17.

[0049] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
