Description

Technical Field

[0001] This application belongs to the technical field of lighting fixtures. More specifically, it relates to an installation structure of a lighting fixture and a lighting fixture. Background Art

[0002] With the continuous development of lighting technology, lighting fixtures have become an indispensable part of modern life. As an important part of lighting fixtures, the rationality of the installation structure of lighting fixtures directly affects the installation convenience, use stability and maintenance efficiency of lighting fixtures. At present, the common installation structures of lighting fixtures on the market mainly include various forms such as screw fixation, snap fixation and magnetic attraction.

[0003] However, although some existing elastic lock structures can achieve the quick installation of lighting fixtures, the installation operation is difficult. It often requires the user to operate with both hands at the same time and requires a large installation force, resulting in insufficient installation flexibility and poor user experience. Summary of the Invention

[0004] The purpose of the embodiments of this application is to provide an installation structure of a lighting fixture and a lighting fixture to solve the problem of insufficient installation flexibility of lighting fixtures in the prior art.

[0005] To achieve the above purpose, in the first aspect, this application provides an installation structure of a lighting fixture, including:

[0006] An installation bracket, including a bracket body and a fastening flange arranged on the peripheral side of the bracket body;

[0007] A lighting fixture base, including a base body and at least one elastic lock. The base body has a light-emitting surface and a backlight surface arranged opposite to each other, and the elastic lock is arranged on the backlight surface;

[0008] Wherein, when the base body moves in the direction of the backlight surface facing the installation bracket, the elastic lock can abut against the surface of the fastening flange facing the base body, and is elastically contracted by the abutting force and crosses over the fastening flange; after the elastic lock crosses over the fastening flange, it elastically resets and abuts against the surface of the fastening flange facing away from the base body to fix the base body in the direction of the light-emitting surface facing away from the installation bracket to the installation bracket.

[0009] In some embodiments of the first aspect, an installation groove is formed on the backlight surface. The installation groove has a first end and a second end in its own extending direction. The elastic lock includes:

[0010] A locking member, slidably connected in the installation groove. When the base body moves in the direction of the backlight surface facing the installation bracket, the locking member can abut against the surface of the fastening flange facing the base body, and slide towards the first end under the abutting force;

[0011] An elastic member is disposed between the locking member and the base body, and can generate a restoring force toward the second end when the locking member slides toward the first end under the abutting force, so that the locking member slides back toward the second end after passing over the fastening flange and abuts against the surface of the fastening flange facing away from the lamp base.

[0012] In some embodiments of the first aspect, a guiding inclined surface is provided at an end of the locking member facing away from the first end. When the base body moves in a direction with its backlight surface facing the mounting bracket, the fastening flange applies the abutting force to the guiding inclined surface to guide the locking member to slide toward the first end.

[0013] In some embodiments of the first aspect, a limiting protrusion protrudes from the surface of the locking member, and the limiting protrusion is used to limit the sliding range of the locking member in the mounting groove.

[0014] In some embodiments of the first aspect, the lamp base further includes a cover plate, which is installed on the base body and shields the notch of the mounting groove.

[0015] In some embodiments of the first aspect, one of the cover plate and the base body is provided with a positioning buckle, and the other is provided with a positioning groove, and the positioning buckle is elastically engaged in the positioning groove.

[0016] In some embodiments of the first aspect, an avoidance groove is formed on the circumferential side of the fastening flange. When the lamp base is fixed to the mounting bracket, it can rotate around the central axis of the fastening flange to the dismounting position where the avoidance groove axially avoids the elastic lock, so that the lamp base can move axially along the fastening flange to be separated from the mounting bracket.

[0017] In some embodiments of the first aspect, a limiting rib protrudes from the fastening flange, and the limiting rib is located on one side of the avoidance groove;

[0018] When the lamp base rotates relative to the fastening flange, the limiting rib can abut against the elastic lock to limit the lamp base at the dismounting position.

[0019] In some embodiments of the first aspect, the number of the elastic locks is at least three, and at least three elastic locks are arranged at intervals along a circumferential path;

[0020] The number of the avoidance grooves is the same as the number of the elastic locks and corresponds one by one. Each avoidance groove corresponds to each elastic lock one by one. When the lamp base is in the dismounting position, each avoidance groove axially avoids the corresponding elastic lock in the mounting direction.

[0021] In some embodiments of the first aspect, the mounting structure further includes a locking member. The bracket body is provided with a hollowed-out portion, and the locking member passes through the hollowed-out portion and is detachably connected to the bracket body.

[0022] In some embodiments of the first aspect, the hollowed-out portion includes at least one through hole and / or at least one elongated hole.

[0023] In a second aspect, the present application further provides a lamp, including a light source assembly and the mounting structure of the lamp described in the first aspect and any of its embodiments. The light source assembly is mounted on the light-emitting surface of the base body.

[0024] In some embodiments of the second aspect, the lamp further includes a light-transmitting cover. The light-transmitting cover is mounted on the base body and forms a receiving cavity between the light-transmitting cover and the light-emitting surface. The light source assembly is disposed in the receiving cavity.

[0025] The beneficial effects of the mounting structure of the lamp and the lamp provided by the present application are as follows: Compared with the prior art, the mounting structure includes a mounting bracket and a lamp base. The mounting bracket includes a bracket body and a fastening flange, and the lamp base includes a base body and an elastic lock. When the base body moves towards the mounting bracket, the elastic lock can abut against the fastening flange and cross over the fastening flange, and after the elastic lock crosses over the fastening flange, it abuts against the other surface of the fastening flange, thereby fixing the lamp base to the mounting bracket. Users can install the lamp without operating with both hands simultaneously and without applying a large installation force, improving the installation convenience and flexibility of the lamp and providing a better user experience.

[0026] Moreover, an avoidance groove is further provided on the circumferential side of the fastening flange. After the lamp base rotates a certain angle around the axis of the fastening flange, the elastic lock can be aligned with the position of the avoidance groove, enabling the elastic lock to pass through the avoidance groove to remove the lamp base from the mounting bracket without tool operation, reducing the maintenance cost.

[0052] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality" is two or more unless otherwise specifically defined.

[0053] In a first aspect, an installation structure of a lamp provided by an embodiment of the present application is used to fix the lamp at an installation position such as a ceiling or a wall. As Figure 1As shown in the figure, the installation structure of the lamp provided by the embodiment of the present application includes an installation bracket 100 and a lamp base 200. The lamp base 200 is detachably connected to the installation bracket 100. During use, first fix the installation bracket 100 at the installation position, and then install the lamp base 200 on the installation bracket 100 to facilitate the installation and use of the lamp.

[0054] As Figure 2 shown, the installation bracket 100 includes a bracket body 110 and a fastening flange 120 provided on the peripheral side of the bracket body 110. The lamp base 200 includes a base body 210 and at least one elastic lock 220. The base body 210 has a light-emitting surface and a backlight surface arranged opposite to each other, and the elastic lock 220 is provided on the backlight surface of the base body 210. When the base body 210 moves in the direction with the backlight surface facing the installation bracket 100, the elastic lock 220 can abut against the surface of the fastening flange 120 facing the base body 210, and elastically contract under the abutting force to cross over the fastening flange 120; after the elastic lock 220 crosses over the fastening flange 120, it elastically resets and abuts against the surface of the fastening flange 120 facing away from the base body 210 to fix the base body 210 in the direction with the light-emitting surface facing away from the installation bracket 100 on the installation bracket 100.

[0055] Specifically, the bracket body 110 is a plate-like or disc-like structure with a certain thickness for providing stable support. The fastening flange 120 can extend outward from the peripheral side of the bracket body 110 to form an annular structure surrounding the bracket body 110. In this embodiment, the bracket body 110 is in a disc-like structure, and the fastening flange 120 is in a circular ring shape and is arranged around the peripheral side of the bracket body 110.

[0056] Among them, the upper surface of the fastening flange 120 is axially spaced from the upper surface of the bracket body 110, so that after the bracket body 110 is fixed at the installation position such as the ceiling or the wall, the upper surface of the fastening flange 120 can be spaced from the installation surface to form a cavity above the fastening flange 120 into which the elastic lock 220 can be inserted. In this embodiment, the peripheral side of the bracket body 110 has a downwardly protruding annular flange, and the fastening flange 120 is arranged around the bottom of the annular flange, so that the upper surface of the fastening flange 120 is spaced from the upper surface of the bracket body 110.

[0057] The connection and fixation of the bracket body 110 to the installation position such as the ceiling or the wall can be arbitrary. In this embodiment, the installation structure may further include a locking member. The bracket body 110 is provided with a hollow portion, and the locking member can pass through the hollow portion and is detachably connected to the bracket body 110. Optionally, the locking member is a bolt 600, and the bolt 600 can be used to pass through the hollow portion and then be fixed to the ceiling to fix the bracket body 110 at the installation position

[0058] Among them, the hollowed-out part may include at least one through hole 1101 and / or at least one strip-shaped hole 1102, so as to be able to adjust the relative positions of the bolt 600 and the bracket body 110 according to actual installation requirements, and achieve flexible fixation of the mounting bracket 100. In this embodiment, the bracket body 110 is provided with a plurality of strip-shaped holes 1102 and two through holes 1101. The strip-shaped holes 1102 extend in an arc along the circumferential direction of the bracket body 110, and the through holes 1101 are arranged at the gaps between adjacent two strip-shaped holes 1102, so as to pass the bolt 600 through the corresponding strip-shaped hole 1102 or through hole 1101 according to different installation methods.

[0059] The base body 210 is a plate-shaped or disc-shaped structure with a certain thickness and area. The light-emitting surface and the backlight surface are the lower surface and the upper surface of the base body 210 respectively. Among them, the backlight surface is used to provide installation positions for the elastic latch 220 and other components, and the light-emitting surface is used to carry components such as the light source assembly 300 of the lamp. In this embodiment, the base body 210 is in a disc-shaped structure, and its diameter is larger than the diameter of the bracket body 110, so as to be adapted to the mounting bracket 100 during installation.

[0060] The upper surface of the lamp base 200 may be convexly provided with a first annular protrusion 211. The axis of the first annular protrusion 211 coincides with the axis of the lamp base 200. The inner diameter of the first annular protrusion 211 is larger than the outer diameter of the buckling flange 120, and the axial height of the first annular protrusion 211 matches the axial height of the entire mounting bracket 100. When the lamp base 200 is connected to the mounting bracket 100, the mounting bracket 100 can be embedded inside the entire first annular protrusion 211 to position the connection and cooperation between the lamp base 200 and the mounting bracket 100.

[0061] Furthermore, the circumferential side of the base body 210 may also be convexly provided with an upward second annular protrusion 212. The second annular protrusion 212 surrounds the outside of the first annular protrusion 211 and is spaced from the first annular protrusion 211. When the lamp base 200 is connected to the mounting bracket 100, the top of the second annular protrusion 212 can abut against the ceiling 500 or the wall surface, closing the upper side of the lamp base 200, protecting the inner mounting bracket 100, elastic latch 220, etc., preventing dust or foreign objects from entering, and improving the aesthetics. Moreover, it can also improve the structural strength of the base body 210 and enhance the overall stability of the lamp.

[0062] The elastic latch 220 can be disposed inside the first annular protrusion 211 so that when the lamp base 200 is connected to the mounting bracket 100, the elastic latch 220 can engage with the upper surface of the engaging flange 120. The elastic latch 220 can be a latch structure made of an elastic material and has a certain elasticity. During the movement of the base body 210 towards the mounting bracket 100, the elastic latch 220 can receive the abutting force of the engaging flange 120 and elastically deform or elastically move towards the direction of the first annular protrusion 211 under the action of the abutting force, so as to cross over the engaging flange 120. After the elastic latch 220 completely crosses over the engaging flange 120, it elastically resets and abuts against the upper surface of the engaging flange 120, preventing the lamp base 200 from moving downward and realizing the stable connection between the lamp base 200 and the mounting bracket 100. In this way, the user can install the lamp base 200 on the mounting bracket 100 with one hand operation, and the required installation force is also small, improving the installation convenience of the lamp.

[0063] Among them, the number of the elastic latches 220 can be arbitrary. Optionally, the number of the elastic latches 220 is at least three, and at least three elastic latches 220 are arranged at intervals in the circumferential direction. Under the action of the three elastic latches 220, three supporting points are formed. By using the function that three supporting points can determine a plane, the stability of the cooperation between the lamp base 200 and the mounting bracket 100 is ensured.

[0064] Refer to Figure 3 , in some embodiments, an installation groove 2101 is formed on the backlight surface of the base body 210. The installation groove 2101 has a first end and a second end in its own extending direction. The elastic latch 220 can include a locking member 221 and an elastic member 222. The locking member 221 is slidably connected in the installation groove 2101, and the elastic member 222 is disposed between the locking member 221 and the base body 210.

[0065] When the base body 210 moves in the direction with its backlight surface facing the mounting bracket 100, the locking member 221 can abut against the surface of the engaging flange 120 facing the base body 210 and slide towards the first end of the installation groove 2101 under the abutting force. The elastic member 222 can generate a restoring force towards the second end when the locking member 221 slides towards the first end under the abutting force, so that the locking member 221 slides towards the second end and resets to abut against the surface of the engaging flange 120 facing away from the lamp base 200 after crossing over the engaging flange 120.

[0066] Among them, the shape of the installation groove 2101 matches the shapes of the locking member 221 and the elastic member 222, so that the locking member 221 and the elastic member 222 can be stably installed in the installation groove 2101, and the locking member 221 can slide along the extending direction of the installation groove 2101. In this embodiment, the installation groove 2101 has a T-shaped structure and extends radially along the base body 210. The installation groove 2101 is located at the first annular protrusion 211. One end of the installation groove 2101 facing the first annular protrusion 211 is the first end, and the end facing away from the first annular protrusion 211 is the second end. The notch of the installation groove 2101 faces upward, and the locking member 221 and the compressed elastic member 222 can enter the installation groove 2101 together from the notch, which is convenient for the assembly of the entire elastic lock 220 and the lamp base 200. The second end of the installation groove 2101 has an opening matching the shape of the locking member 221 for the end of the locking member to extend out through the opening.

[0067] The locking member 221 can be a block structure extending radially along the base body 210. The elastic member 222 can be a spring, a spring piece or other elastic elements. The elastic member 222 is located on the side of the locking member 221 facing the first annular protrusion 211. One end of the elastic member 222 abuts against the locking member 221, and the other end abuts against the inner wall of the installation groove 2101 to store energy when the locking member 221 slides towards the first end of the installation groove 2101.

[0068] When the lamp base 200 is connected to the mounting bracket 100, the end of the locking member 221 extending out of the installation groove 2101 is used to bear the abutting force of the buckling flange 120, and can slide towards the first end of the installation groove 2101 and contract into the interior of the installation groove 2101 under the abutting force.

[0069] Optionally, a guiding inclined surface 2211 is provided at the end of the locking member 221 facing away from the first end. When the base body 210 moves towards the mounting bracket 100, the buckling flange 120 applies an abutting force to the guiding inclined surface 2211 to guide the locking member 221 to slide towards the first end and contract into the installation groove 2101. Among them, the inclination direction of the guiding inclined surface 2211 is consistent with the sliding direction of the locking member 221, and the inclination angle of the guiding inclined surface 2211 can be 45° - 65°.

[0070] Refer to Figures 4 - 6, when the locking member 221 is not under the action of other external forces, the end of the locking member 221 with the guiding inclined surface 2211 extends out of the installation groove 2101 and corresponds to the position of the fastening flange 120. During the process of moving the lamp base 200 upward to connect with the installation bracket 100, the guiding inclined surface 2211 abuts against the lower surface of the fastening flange 120. Under the action of the guiding inclined surface 2211, a component force along the radial direction of the lamp base 200 is decomposed from the abutting force, so as to be able to drive the locking member 221 to slide towards the elastic member 222, retract the locking member 221 inside the installation groove 2101, and compress the elastic member 222 to store energy. When the locking member 221 passes over the fastening flange 120, the fastening flange 120 no longer applies an external force to the locking member 221. At this time, the locking member 221 extends out of the installation groove 2101 again under the action of the elastic member 222 and abuts against the upper surface of the fastening flange 120 to limit the displacement of the lamp base 200 in the vertical direction.

[0071] Referring to Figure 7 , in another embodiment, the lower surface of the fastening flange 120 can also be set as a conical surface. At this time, the end surface of the locking member 221 extending out of the installation groove 2101 can be set as an arc surface. When the locking member 221 moves upward and contacts the lower surface of the fastening flange 120, the vertical abutting force can also be decomposed into a radial component force to drive the locking member 221 to slide, achieving the purpose of elastically moving the locking member 221 over the fastening flange 120.

[0072] Furthermore, a limiting protrusion 2212 can be convexly provided on the surface of the locking member 221. The limiting protrusion 2212 is used to limit the sliding range of the locking member 221 in the installation groove 2101. Specifically, the shape of the opening of the installation groove 2101 for the locking member 221 to extend out matches the shape of the locking member 221. The limiting protrusion 2212 convexly provided on the surface of the locking member 221 cannot pass through the opening of the installation groove 2101. Therefore, when the locking member 221 extends out of the installation groove 2101 under the elastic force of the elastic member 222, the limiting protrusion 2212 can abut against the inner wall of the installation groove 2101 at its opening to limit the extending length of the locking member 221 and prevent the locking member 221 from disengaging from the installation groove 2101. In this embodiment, two limiting protrusions 2212 are provided on both the upper and lower surfaces of the locking member 221, and the limiting protrusions 2212 extend along the sliding direction of the locking member 221. The limiting protrusions 2212 can not only limit the sliding range of the locking member 221, but also contact the inner wall of the installation groove 2101 instead of the surface of the locking member 221, so as to reduce the contact area between the locking member 221 and the inner wall of the installation groove 2101, reduce the friction force when the locking member 221 slides, and ensure the smooth extension or retraction of the locking member 221.

[0073] In some embodiments, the lamp base 200 may further include a cover plate 230. The cover plate 230 is installed on the base body 210 and shields the notch of the installation groove 2101 to enclose the entire elastic latch 220 inside the installation groove 2101, preventing the locking member 221 and the elastic member 222 from disengaging from the installation groove 2101. It can also block dust or foreign objects from entering the installation groove 2101, ensuring the stable use of the locking member 221 and the elastic member 222.

[0074] The shape of the cover plate 230 can be designed according to the shape of the notch of the installation groove 2101. When there are multiple elastic latches 220 provided on the base body 210, there are multiple corresponding installation grooves 2101 on the base body 210. A cover plate 230 can be independently provided at each installation groove 2101 to enclose the installation groove 2101, or a single cover plate 230 can be used to cover the notches of all installation grooves 2101 at the same time.

[0075] Combined with Figure 2 As shown, in this embodiment, the cover plate 230 has an annular structure and fits into the annular cavity between the first annular protrusion 211 and the second annular protrusion 212. And a protrusion structure protrudes inward at the position corresponding to the installation groove 2101 on the inner side of the annular structure. When the cover plate 230 is installed on the lamp base 200, the annular structure of the cover plate 230 covers the annular cavity, and the protrusion structure shields the notch of the corresponding installation groove 2101. In this embodiment, the cover plate 230 is fixedly connected to the base body 210 by screws. In other embodiments, it can also be connected and fixed to the base body 210 by means of clamping, bonding, etc.

[0076] Furthermore, referring to Figure 4 , one of the cover plate 230 and the base body 210 is provided with a positioning buckle 231, and the other is provided with a positioning groove 2102. The positioning buckle 231 is elastically clamped in the positioning groove 2102. When the cover plate 230 is installed on the base body 210, the positioning buckle 231 is clamped in the positioning groove 2102, which can position the cover plate 230 and prevent the cover plate 230 from shaking after installation.

[0077] In this embodiment, a plurality of positioning buckles 231 are provided on the circumferential side of the cover plate 230, and a plurality of positioning grooves 2102 are opened on the inner wall of the second annular protrusion 212. When installing the cover plate 230, the positioning buckles 231 can be elastically deformed and snap into the corresponding positioning grooves 2102 to position the installation position of the cover plate 230.

[0078] Combined with Figures 8 - 10As shown, in some embodiments, an avoidance groove 1201 is formed on the circumferential side of the fastening flange 120. When the lamp base 200 is fixed to the mounting bracket 100, it can rotate around the central axis of the fastening flange 120 to the disassembly position where the avoidance groove 1201 axially avoids the elastic latch 220, so that the lamp base 200 can move axially to separate from the mounting bracket 100.

[0079] Specifically, the avoidance groove 1201 is a groove structure formed on the circumferential side of the fastening flange 120. The number of the avoidance grooves 1201 is the same as that of the elastic latches 220, and the avoidance grooves 1201 are evenly distributed along the circumferential direction of the fastening flange 120 to ensure that when the lamp base 200 is disassembled, the elastic latch 220 can smoothly rotate to the position of the avoidance groove 1201. The opening length of the avoidance groove 1201 is greater than the width of the elastic latch 220 along the circumferential direction of the fastening flange 120 to ensure that when the elastic latch 220 rotates to the position of the avoidance groove 1201, the elastic latch 220 can completely escape from the avoidance groove 1201.

[0080] When disassembling the lamp base 200, the lamp base 200 can be manually rotated to make the elastic latch 220 rotate to the position of the avoidance groove 1201. At this time, the elastic latch 220 is no longer blocked by the fastening flange 120, and the lamp base 200 can move vertically downward to move the elastic latch 220 out of the avoidance groove 1201, thereby separating the lamp base 200 from the mounting bracket 100, achieving the purpose of disassembling the lamp base 200, making the installation and disassembly of the lamp base 200 and the mounting bracket 100 more convenient, without the need to use additional disassembly tools, and reducing the difficulty of disassembling the lamp base 200.

[0081] Refer to Figure 9 , further, a limiting rib 121 is also protruded on the fastening flange 120. The limiting rib 121 is located on one side of the avoidance groove 1201; when the lamp base 200 rotates relative to the fastening flange 120, the limiting rib 121 can abut against the elastic latch 220 to limit the lamp base 200 at the disassembly position.

[0082] The limiting rib 121 is a convex strip structure extending along the axial direction of the fastening flange 120. One end of the limiting rib 121 is connected to one side edge of the fastening flange 120, and the other end bends and extends towards the inner side of the fastening flange 120. The number of the limiting ribs 121 is the same as that of the avoidance grooves 1201, and the limiting ribs 121 are arranged in one-to-one correspondence on one side of the avoidance grooves 1201.

[0083] When the lamp base 200 rotates relative to the fastening flange 120, the limiting rib 121 can abut against the elastic latch 220 to provide a tactile feedback to the user, enabling the user to know that the lamp base 200 has rotated to the disassembly position. At this time, the elastic latch 220 is exactly corresponding to the avoidance groove 1201, and the lamp base 200 can move downward to move the elastic latch 220 out of the avoidance groove 1201, thereby separating the lamp base 200 from the mounting bracket 100. The provision of the limiting rib 121 can ensure that the lamp base 200 can stably stay at the disassembly position during disassembly, facilitating the user's disassembly work of the lamp.

[0084] It can be understood that in the above embodiment, the fastening flange 120 is an annular structure extending outward from the peripheral side of the bracket body 110, and the elastic latch 220 moves in the direction away from the axis of the base body 210 to avoid on one side of the fastening flange 120 when receiving a resisting force. In other embodiments, the fastening flange 120 can also extend inward from the peripheral side of the bracket body 110 to form an annular structure spaced apart from the bracket body 110.

[0085] Referring to Figure 11 , in another embodiment, the fastening flange 120 can also be disposed around the inner side of the annular flange at the bottom of the bracket body 110. The upper surface of the fastening flange 120 is spaced apart from the lower surface of the mounting bracket 100 to form a cavity for the elastic latch 220 to snap into. The outer diameter of the first annular protrusion 211 can be smaller than the inner diameter of the fastening flange 120, and the elastic latch 220 is disposed outside the first annular protrusion 211. The elastic latch 220 moves in the direction towards the axis of the base body 210 to avoid on one side of the fastening flange 120 when receiving a resisting force. When the locking member 221 passes over the fastening flange 120, it snaps onto the upper surface of the fastening flange 120, also achieving the purpose of connecting the lamp base 200 to the mounting bracket 100.

[0086] In summary, the installation structure of the lamp provided by the embodiments of the present application realizes the stable connection between the lamp base 200 and the mounting bracket 100 through the engagement and limitation of the elastic latch 220 and the fastening flange 120. When it is necessary to disassemble the lamp, the user only needs to rotate the lamp base 200 relative to the fastening flange 120 to the disassembly position so that the elastic latch 220 is opposite to the avoidance groove 1201, and then the lamp base 200 can be separated from the mounting bracket 100. The user can install and disassemble the lamp with one hand without using any tools, improving the user experience.

[0087] In a second aspect, the embodiments of the present application also provide a lamp. Referring to Figure 12 , the lamp provided by the embodiments of the present application includes a light source assembly 300 and the installation structure of the lamp in the first aspect embodiment, and the light source assembly 300 is installed on the light-emitting surface of the lamp base 200.

[0088] Among them, the light source component 300 can be an LED light board, a fluorescent lamp tube, a halogen lamp bulb or other types of lighting elements, and is selected according to the actual application scenario and lighting requirements. The light source component 300 can be integrally arranged with the lamp base 200 to form an integrated structure, simplifying the assembly process of the lamp. The light source component 300 can also be detachably installed on the lamp base 200 by means of fasteners, buckles, etc., so as to facilitate the replacement or maintenance of the light source component 300.

[0089] During the use of the lamp, the light source component 300 emits light to provide illumination, while the installation structure of the lamp ensures that the lamp can be stably installed at a predetermined position, preventing the lamp from shaking or falling off during use. Through the engagement and limitation of the elastic lock 220 and the engaging flange 120, the installation structure of the lamp not only realizes the stable connection between the lamp base 200 and the mounting bracket 100, but also makes the installation and disassembly process of the lamp more convenient, without the need for additional tools, reducing the operation difficulty for users.

[0090] Furthermore, the lamp may further include a light-transmitting cover 400. The light-transmitting cover 400 is installed on the base body 210 and forms a receiving cavity between the light-transmitting cover 400 and the light-emitting surface of the base body 210. The light source component 300 is disposed in the receiving cavity.

[0091] The light-transmitting cover 400 can be a transparent or semi-transparent cover body, and its material can be glass, plastic or other light-transmitting materials. The light-transmitting cover 400 is installed on the lower surface of the base body 210, and a part of the light-transmitting cover 400 is spaced apart from a part of the base body 210 to form a receiving cavity. By disposing the light source component 300 in the receiving cavity, on the one hand, the light source component 300 can be protected from being directly exposed to the external environment and damaged; on the other hand, the light-transmitting cover 400 can diffuse or focus the light emitted by the light source component 300 to meet different lighting requirements. The shape and size of the light-transmitting cover 400 can be customized according to the specific design and use scenario of the lamp to achieve the best lighting effect and aesthetics.

[0092] In this embodiment, a receiving groove 2103 is formed on the light-emitting surface of the base body 210. The light source component 300 can be fixed in the receiving groove 2103, and the light-transmitting cover 400 covers the opening of the receiving groove 2103 to form a receiving cavity between the light-transmitting cover 400 and the inner wall of the receiving groove 2103. Among them, the light-transmitting cover 400 can be detachably connected to the inner wall of the receiving groove 2103 by means of a snap structure, so as to facilitate the maintenance and replacement of the internal light source component 300.

[0093] The lamp provided by the embodiment of the present application can be directly installed on the ceiling 500, such as Figure 13As shown, a wiring hole 501 is provided at the position on the ceiling 500 where the lamp is installed, for the power cord to pass through and be connected to the light source assembly 300 inside the lamp base 200. During installation, bolts 600 are used to pass through the elongated holes 1102 or through holes 1101 at corresponding positions on the mounting bracket 100, and the mounting bracket 100 is fixed at the wiring hole 501 of the ceiling 500. After connecting the power cord to the light source assembly 300, the lamp base 200 is then installed on the mounting bracket 100, and thus the lamp can be fixed on the ceiling 500.

[0094] Referring to Figure 14 , the lamp in this embodiment can also be installed on the ceiling 500 through a junction box 510 (Junction Box, J - BOX). Specifically, the junction box 510 is usually installed on the ceiling 500. The interior of the junction box 510 is hollow and its bottom is open, and several first threaded holes for screwing in bolts 600 are provided at the opening of the junction box 510. During installation, first, the junction box 510 is fixed on the ceiling 500, aligning the opening of the junction box 510 with the wiring hole 501, and at the same time exposing the first threaded holes at the wiring hole 501. Bolts 600 are used to pass through the elongated holes 1102 or through holes 1101 at corresponding positions on the mounting bracket 100 and then screwed into the first threaded holes to fixedly connect the mounting bracket 100 below the junction box 510. Finally, the lamp base 200 is snapped onto the mounting bracket 100 to complete the installation of the lamp.

[0095] Referring to Figure 15 , the lamp in this embodiment can also be installed on the ceiling 500 through an electrical wiring barrel 520 (Underwriters Laboratories - Can, UL barrel). Specifically, the electrical wiring barrel 520 is a barrel - shaped structure with an open bottom, and a second threaded hole is provided at the opening of the electrical wiring barrel 520. During installation, the electrical wiring barrel 520 is fixed on the ceiling 500, aligning the opening of the electrical wiring barrel 520 with the wiring hole 501 of the ceiling 500, and at the same time exposing the second threaded holes at the wiring hole 501.
