[0054] For ease of description, unless otherwise specified, the descriptions of up, down, left, right, front and back in this article are all based on the state when the wall panel is the ceiling, and the wall panel is located above the downlight, and the lamp mounting assembly is located at the top of the lamp body.

[0055] A downlight is a lighting device that is embedded in a wall panel or wall. Existing home downlights have spring clips on both sides of the lamp body, which are inserted into the slots of the wall panel. However, the spring clips have a large elastic force, and operators need to pry open the springs and keep them open during the installation process, which is very laborious. In addition, the spring clips are easy to pinch hands when they are installed and pressed, making installation difficult.

[0056] Based on this, in order to solve the above problems, the present application designs a lamp installation assembly, in which the installation clip forms a three-link assembly through an elastic member and a support, so that the operator can easily and labor-savingly turn the installation clip to rotate and adjust it to the first position, and the installation clip can be maintained in the first position without the action of external force. Therefore, during the installation of the downlight, the installation clip can be conveniently inserted into the installation hole of the wall panel; after the installation clip is inserted into the installation hole, the installation clip is controlled to rotate downward to change the shape of the three-link assembly, and the installation clip will quickly rotate to the second position under the elastic force of the elastic member, thereby realizing the automatic installation of the downlight. The entire installation process is simple and quick, effectively reducing the difficulty of installation.

[0057] refer to Figure 8 , Figure 9 and Figures 10 to 14, an embodiment of the present application provides a downlight for being installed in a to-be-installed hole 310 on a wall panel 300; the downlight includes a lamp body 200 and a lamp fixture mounting assembly 100 provided on the lamp body 200.

[0058] Understandably, referring to Figures 11 - 14 , at least two groups of lamp fixture mounting assemblies 100 are provided on the lamp body 200, and the lamp body 200 is installed on the wall panel 300 through the lamp fixture mounting assemblies 100; the lamp fixture mounting assemblies 100 are used to be installed in the to-be-installed holes 310, and the lamp body 200 is fixed through the lamp fixture mounting assemblies 100, so that the lamp body 200 is in close contact with the wall panel 300 and the lamp body 200 is restricted from detaching from the wall panel 300.

[0059] Referring to Figures 1 to 5 , in some embodiments, the lamp fixture mounting assembly 100 includes a support 1, a mounting clip 2 and an elastic member 3; the mounting clip 2 is rotatably connected to the support 1; two ends of the elastic member 3 are respectively connected to the support 1 and the mounting clip 2; the elastic member 3, the mounting clip 2 and the support 1 form a three-link assembly 4; the mounting clip 2 can rotate relative to the support 1 between a first position and a second position; in the first position, the mounting clip 2 is located above the support 1, and the mounting clip 2 abuts against the support 1 and maintains balance through the three-link assembly 4; during the process of the mounting clip 2 rotating from the first position to the second position, the mounting clip 2 will be rotated to the outside of the support 1 under the action of the elastic member 3.

[0060] Specifically, referring to Figures 8 to 10 , at least two groups of lamp fixture mounting assemblies 100 are provided on the lamp body 200; the lamp body 200 includes a face ring 210 facing away from the wall panel 300 and a back plate 220 facing the wall panel 300; the support 1 is provided on the back plate 220.

[0061] Exemplarily, the number of the lamp fixture mounting assemblies 100 can be two, and the two lamp fixture mounting assemblies 100 are symmetrically arranged on opposite sides of the lamp body 200; alternatively, the number of the lamp fixture mounting assemblies 100 can be multiple, and the multiple lamp fixture mounting assemblies 100 are spaced apart around the center of the lamp body 200.

[0062] The installation steps of the downlight are specifically as follows: Referring to Figure 3 , Figure 4 , the mounting clip 2 is rotated upward in advance to the first position, the mounting clip 2 will be located above the support 1, the free end 201 of the mounting clip 2 (the end of the mounting clip 2 farthest from the support 1) faces the top side of the support 1, the mounting clip 2 abuts against the support 1 and can maintain force balance under the action of the three-link assembly 4, so as to maintain in the first position; referring to Figure 11 and Figure 12 , an operator holds the lamp body 200 and raises it, and inserts the mounting clip 2 into the to-be-installed hole 310 of the wall panel 300; referring to Figure 12 Figure 13, after the mounting clip 2 to be installed extends into the mounting hole 310 to be installed, the operator controls the mounting clip 2 to rotate downward, the shape of the three-link assembly 4 will change, and the mounting clip 2 will rotate downward relative to the support 1 to the outside of the support 1 under the elastic force of the elastic member 3, so that the free end 201 of the mounting clip 2 will face the bottom side of the support 1. Subsequently, the mounting clip 2 will press against the wall panel 300, thereby lifting the lamp body 200 upward, making the lamp body 200 close to the wall panel 300. The mounting clip 2 can limit the lamp body 200 from falling, thus realizing the automatic installation of the lamp body 200.

[0063] For the lamp mounting assembly 100 of the present application, the mounting clip 2 can rotate between a first position and a second position, and the mounting clip 2 forms a three-link assembly 4 through the elastic member 3 and the support 1, so that it is easy and labor-saving for the operator to turn and adjust the mounting clip 2 to the first position, and the mounting clip 2 can maintain in the first position without external force. Therefore, during the installation of the downlight, the mounting clip 2 can be conveniently extended into the mounting hole 310 of the wall panel 300; after the mounting clip 2 extends into the mounting hole 310 to be installed, controlling the mounting clip 2 to rotate downward changes the shape of the three-link assembly 4, and the mounting clip 2 will quickly rotate to the second position under the elastic force of the elastic member 3, thereby realizing the automatic installation of the downlight. The whole installation process is simple and fast, effectively reducing the installation difficulty and facilitating the user to install by himself.

[0064] Reference Figures 3 to 7 , in some embodiments, the three-link assembly 4 includes a first force application point 5 where the elastic member 3 is connected to the support 1, a second force application point 6 where the elastic member 3 is connected to the mounting clip 2, and a hinge point 7 where the mounting clip 2 is rotatably connected to the support 1; in the first position, the hinge point 7 is lower than the second force application point 6; in the second position, the hinge point 7 is higher than the second force application point 6.

[0065] It can be understood that the connection lines between the first force application point 5, the second force application point 6 and the hinge point 7 enclose a triangle, forming a three-link assembly 4 with a stable structure and improving the stability of the overall structure.

[0066] Specifically, the present application uses a three-link structure. During the rotation of the mounting clip 2 relative to the support 1, the shape of the triangle formed by the first force application point 5, the second force application point 6 and the hinge point 7 changes accordingly, and the effect of the elastic force exerted by the elastic member 3 on the mounting clip 2 changes accordingly.

[0067] Reference Figure 3 , Figure 4, the mounting clip 2 is in the first position, and the hinge point 7 is located below the second force point 6. At this time, the elastic member 3 is in a stretched state, and the elastic member 3 will apply an oblique upward elastic force to the mounting clip 2, so that the mounting clip 2 has an elastic force to rotate upward relative to the support 1; the mounting clip 2 further abuts against the support 1 to balance the elastic force of the elastic member 3, and then the mounting clip 2 can maintain a force balance in the first position, and then the operator can detach both hands from the mounting clip 2 after rotating the mounting clip 2 upward to the first position, and the mounting clip 2 can stay stably in the first position, thereby reducing the difficulty of subsequent installation of the downlight.

[0068] refer to Figure 6 , Figure 7 When the mounting clip 2 is inserted into the mounting hole 310, a force is applied to the mounting clip 2 to control the mounting clip 2 to rotate downward relative to the support 1; when the second force point 6 is lower than the hinge point 7, the elastic member 3 will elastically contract to cause the mounting clip 2 to rotate downward quickly, so that the mounting clip 2 falls quickly and is fixed to the wall panel. Then the operator only needs to apply a small rotation force to the mounting clip 2. When the second force point 6 is lower than the hinge point 7, the force of the elastic member 3 can be triggered, and the mounting clip 2 will realize the automatic installation function under the action of the elastic member 3, which is convenient and easy to operate.

[0069] refer to Figures 3 to 7 In some embodiments, the mounting clip 2 further has a trigger position between the first position and the second position, and in the trigger position, the first force point 5, the hinge point 7 and the second force point 6 are on the same straight line.

[0070] Specifically, during the process of the installation clip 2 rotating downward from the first position to the trigger position, the operator needs to apply a force to the installation clip 2 to drive the installation clip 2 to rotate; when the installation clip 2 rotates downward from the first position and exceeds the trigger position, the elastic member 3 will provide an elastic force to drive the installation clip 2 to automatically rotate to the second position, and then the installation clip 2 can be automatically installed under the action of the elastic member 3. It can be understood that during the process of the operator driving the installation clip 2 to rotate from the first position to the second position, the trigger position can be regarded as a critical position, that is, when the installation clip 2 rotates downward to exceed the trigger position, the elastic force of the elastic member 3 will be triggered, and the subsequent rotation of the installation clip 2 does not require the operator to apply a force, and the elastic member 3 will automatically drive the installation clip 2 to automatically rotate to the second position to achieve automatic installation. On the contrary, when the operator moves the mounting clip 2 from the second position to the first position, when the mounting clip 2 rotates upward and exceeds the trigger position, the elastic force of the elastic member 3 will be triggered, and the elastic member 3 will provide the elastic force to rotate the mounting clip 2 upward, thereby controlling the mounting clip 2 to move upward to the first position without any effort, thereby effectively reducing the difficulty of operation.

[0071] refer to Figure 4 and Figure 7, in some embodiments, the distance between the first force application point 5 and the second force application point 6 is L1, the distance between the first force application point 5 and the hinge point 7 is L2, and the distance between the second force application point 6 and the hinge point 7 is L3; wherein, 1 / 3L2 > L3 > 1 / 4L2.

[0072] It can be understood that the distance between the first force application point 5 and the hinge point 7 is L2 and remains unchanged. The length of L3 is designed to be appropriate with reference to the length of L2. Specifically, during the rotation of the mounting clip 2 between the first position and the second position, L3 satisfies being between one-third and one-fourth of L2; thus, whether it is the force for controlling the mounting clip 2 to rotate upward to the first position or the force for controlling the mounting clip 2 to rotate downward to trigger the spring action, both are within an appropriate range, making the operation easy and labor-saving.

[0073] Specifically, when the mounting clip 2 is in the trigger position, the first force application point 5, the hinge point 7, and the second force application point 6 are on the same straight line, so L3 = L1 = L2.

[0074] Reference Figure 2 、 Figure 4 and Figure 7 , in some embodiments, the mounting clip 2 includes a clamping portion 21 and a rotating portion 22 provided on the clamping portion 21. The clamping portion 21 and the rotating portion 22 form an angle; the rotating portion 22 is hinged to the support 1 at the hinge point 7; the elastic member 3 is connected to the rotating portion 22 at the second force application point 6.

[0075] In specific applications, the clamping portion 21 is used to abut against the wall panel 300 to realize the installation of the downlight. The clamping portion 21 has a long rod structure. Using the lever principle, an operator can easily control the rotation of the rotating portion 22 relative to the support 1 by grasping the clamping portion 21, making the operation more labor-saving and facilitating the operator to perform the installation.

[0076] Specifically, the clamping portion 21 can be in an L shape. When the clamping portion 21 presses against the wall panel 300, the free end 201 of the clamping portion 21 abuts against the wall panel 300, and the other end of the clamping portion 21 rises to drive the lamp body 200 to rise.

[0077] Reference Figure 1 、 Figure 3 and Figure 4 , in some embodiments, in the first position, the rotating portion 22 forms a pressing portion 8 extending outward from the support.

[0078] Specifically, during the movement of the mounting clip 2 from the first position to the second position, it is necessary for the operator to manually control the mounting clip 2 to rotate from the first position to the trigger position in order to trigger the elastic action of the elastic member 3. Therefore, the operator needs to apply a force to the mounting clip 2; reference Figure 4, the rotating part 22 extends to the outside of the support 1 and forms a pressing part 8. The hinge point 7 is located between the rotating part 22 and the clamping part 21. Then, an operator can control the installation clip 2 to rotate downward around the hinge point 7 by acting on the pressing part 8. For example, by pulling down the pressing part 8, until the installation clip 2 exceeds the trigger position, triggering the elastic action of the elastic member 3, and the operator's hand can leave the pressing part 8. The elastic member 3 contracts to quickly drive the installation clip 2 to rotate.

[0079] Exemplarily, the elastic member 3 can be a tension spring; the pressing part 8 can be, but is not limited to, a plate body, a convex structure, a cross bar, etc.

[0080] Reference Figures 10 to 12 , in some embodiments, when the installation clip 2 is in the first position, the horizontal distance between the free end 201 of the installation clip 2 and the central axis of the lamp body 200 is W1; the horizontal distance between the end of the pressing part 8 and the central axis of the lamp body 200 is W2; the radius of the lamp body 200 is W3, and the radius of the installation hole 310 to be installed is W4; W3 > W2 > W4 > W1.

[0081] It can be understood that when the installation clip 2 is in the first position, W4 > W1 to ensure that the installation clip 2 can penetrate into the installation hole 310 to be installed without interference with the wall panel 300. W2 > W1 to ensure that the pressing part 8 can extend beyond the edge of the installation hole 310 to be installed, facilitating the operator to pull down the pressing part 8 to drive the installation clip 2 to rotate; W3 > W4, after the lamp body 200 is in close contact with the wall panel 300, the lamp body 200 can cover the installation hole 310 to be installed.

[0082] Reference Figure 1 , Figure 2 , Figure 4 and Figure 7 , in some embodiments, the lamp installation assembly 100 further includes a rotating connecting rod 9. The rotating part 22 and the support 1 are rotationally matched through the rotating connecting rod 9; avoidance grooves 10 are formed on the rotating part 22 and the clamping part 21, the elastic member 3 passes through the avoidance grooves 10, and one end of the elastic member 3 is connected to the rotating connecting rod 9.

[0083] Specifically, the rotating part 22 and the support 1 are rotationally matched through the rotating connecting rod 9, and the rotating structure is stable; and the end of the elastic member 3 is connected to the rotating connecting rod 9, and the connection is convenient and fast. Avoidance grooves 10 are formed on the installation clip 2, the avoidance grooves 10 extend from the rotating part 22 to the clamping part 21, and the elastic member 3 is arranged in the avoidance grooves 10. Then, the installation clip 2 will not interfere with the elastic member 3 during the rotation process, and does not affect the elastic force of the elastic member 3 on the installation clip 2, and the structural design is reliable.

[0084] Reference Figure 1 and Figure 2, in some embodiments, the support 1 includes side plates 101 arranged oppositely and an accommodation space 130 formed between the two side plates 101. The rotating part 22 is accommodated in the accommodation space 130. The rotating part 22 includes a transverse plate 221 and vertical plates 222 arranged on opposite sides of the transverse plate 221; the vertical plates 222 are rotatably matched with the adjacent side plates 101 by rotating connecting rods 9.

[0085] Specifically, the support 1 has a U-shaped structure, and an accommodation space 130 for accommodating the rotating part 22 is formed inside the support 1; the rotating part 22 is arranged in the accommodation space, and the vertical plates 222 on both sides are respectively close to the side plates 101 on both sides of the support 1; the rotating connecting rod 9 is horizontally arranged between the two vertical plates 222, and any end of the rotating connecting rod 9 penetrates through the vertical plate 222 and the side plate 101.
