[0026] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] The lamp body assembly disclosed in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0028] Please refer to Figure 1-Figure 9 The present application discloses a lamp body assembly, which includes a reflector 200 and a face ring 300 .

[0029] The lamp body assembly disclosed in the present application is used to be connected to the lamp head assembly 100 of the lighting fixture, that is, the lamp body assembly is used to cooperate with the lamp head assembly 100 to form the lighting fixture.

[0030] The reflector 200 is used to reflect light. Specifically, the side surface of the reflector 200 is an inclined surface, which faces the external environment, so that the reflector 200 can reflect the light irradiated on the side surface to the external environment. The face ring 300 can be mounted on the reflector 200 to protect the reflector 200. At the same time, the face ring 300 can be used as the peripheral structure of the lighting fixture to play a certain decorative role.

[0031] One of the reflector 200 and the face ring 300 is protrudingly provided with a first elastic buckle 210 and a second elastic buckle 220, the first elastic buckle 210 and the second elastic buckle 220 are spaced apart on the one, and the first elastic buckle 210 and the second elastic buckle 220 are deformable, and the other of the reflector 200 and the face ring 300 is provided with a first buckle groove 310 and a second buckle groove 320, the first buckle groove 310 and the second buckle groove 320 are spaced apart on the other.

[0032] When the face ring 300 is sleeved on the reflector 200, the first elastic buckle 210 is deformed to cooperate with the first buckle groove 310 in the vertical direction and in the upper limit position in the first direction, and the second elastic buckle 220 is deformed to cooperate with the second buckle groove 320 in the vertical direction and in the upper limit position in the second direction. The first direction and the second direction are both the directions of the circumference of the face ring 300, and the first direction and the second direction are opposite. That is, when the face ring 300 is sleeved on the reflector 200, the first elastic buckle 210 and the first buckle groove 310 and the second elastic buckle 220 and the second buckle groove 320 can make the reflector 200 and the face ring 300 relatively stationary in the vertical direction and in the circumference of the face ring 300, thereby completing the assembly of the reflector 200 and the face ring 300.

[0033] In the present application, during the process of assembling the face ring 300 and the reflector 200, the face ring 300 and the reflector 200 can be limitedly matched by the limited matching of the first elastic buckle 210 and the first buckle groove 310 and the limited matching of the second elastic buckle 220 and the second buckle groove 320, so as to realize the assembly of the face ring 300 and the reflector 200, and the present application can connect the face ring 300 and the reflector 200 only by the deformation of the first elastic buckle 210 and the second elastic buckle 220, so that when assembling the face ring 300 and the reflector 200, the present application can reduce the assembly time, thereby improving the installation efficiency. Therefore, the lighting fixture disclosed in the present application can solve the problem that the lighting fixture involved in the related art is prone to low installation efficiency.

[0034] Optionally, the face ring 300 may be protrudingly provided with a first elastic buckle 210 and a second elastic buckle 220 , and a notch 330 may be opened on the side wall of the reflector 200 , and a first buckle groove 310 and a second buckle groove 320 are provided on the side of the notch 330 .

[0035] In another embodiment, please refer to Figure 4 and Figure 5, the reflector 200 is provided with a first elastic buckle 210 and a second elastic buckle 220 protruding therefrom. Specifically, when the face ring 300 is sleeved on the reflector 200, the reflector 200 has a side wall facing the face ring 300, on which the first elastic buckle 210 and the second elastic buckle 220 are protruding therefrom. A notch 330 is provided on the side wall of the face ring 300, and a first buckle groove 310 and a second buckle groove 320 are provided on the side of the notch 330. When the face ring 300 is sleeved on the reflector 200, the first elastic buckle 210 and the second elastic buckle 220 correspond to the first buckle groove 310 and the second buckle groove 320 one by one, and are limitedly matched. In this embodiment, since the side wall of the reflector 200 is not provided with a notch 330, the area of ​​the side wall of the reflector 200 is not easily affected, and thus the reflection effect of the reflector 200 on light is not easily affected.

[0036] Optionally, the lamp body assembly also includes a retaining spring 400 for mounting the lamp body assembly on a mounting base, which may be a ceiling or other component. Specifically, one end of the retaining spring 400 may be connected to the reflector 200 and / or the face ring 300, and the other end of the retaining spring 400 may abut against the mounting base in the vertical direction to prevent the lamp body assembly from being separated from the mounting base, and the retaining spring 400 may not be provided with the locking portion 410 described later, that is, the present application is not provided with the locking portion 410 described later.

[0037] In another embodiment, the retaining spring 400 is provided with a locking portion 410. When the face ring 300 is sleeved on the reflector 200 and the retaining spring 400 is respectively connected to the face ring 300 and the reflector 200, the locking portion 410 is located between the first elastic buckle 210 and the second elastic buckle 220, that is, when the retaining spring 400 is installed on the face ring 300 and the reflector 200, the locking portion 410 can be located between the first elastic buckle 210 and the second elastic buckle 220, and at this time, the locking portion 410 can be in abutment contact with the first elastic buckle 210 and the second elastic buckle 220 in the circumferential direction of the face ring 300, that is, at this time, the locking portion 410 can prevent the first elastic buckle 210 and the second elastic buckle 220 from deforming in a direction approaching each other, thereby preventing the first elastic buckle 210 and the second elastic buckle 220 from being separated from the first buckle groove 310 and the second buckle groove 320, thereby preventing the assembly failure of the face ring 300 and the reflector 200.

[0038] It can be seen that, in this embodiment, the locking portion 410 can enable the face ring 300 and the reflector 200 to achieve a self-locking effect. At the same time, since the locking portion 410 is a part of the retaining spring 400, this allows the present application to make full use of the retaining spring 400 and to allow the components on the lamp body assembly to be more centrally arranged, thereby improving the assembly efficiency of the lamp body assembly.

[0039] Optionally, refer to Figure 1 The locking portion 410 may include a first locking portion 411 and a second locking portion 412. The reflector 200 may also be provided with a first limiting plate 230 protruding therefrom. The first limiting plate 230 has a certain limiting effect. Specifically, the first limiting plate 230 is located between the first elastic buckle 210 and the second elastic buckle 220. When the face ring 300 is sleeved on the reflector 200 and the retaining spring 400 is connected to the face ring 300 and the reflector 200, respectively, the first limiting plate 230 is located between the first elastic buckle 210 and the second elastic buckle 220. A locking portion 411 is located between the first elastic buckle 210 and the first limiting plate 230, and the first locking portion 411 can abut against the first elastic buckle 210 and the first limiting plate 230 in the circumferential direction of the face ring 300. The second locking portion 412 is located between the second elastic buckle 220 and the first limiting plate 230, and the second locking portion 412 can abut against the second elastic buckle 220 and the first limiting plate 230 in the circumferential direction of the face ring 300.

[0040] In this embodiment, since the first limiting plate 230 is located between the first elastic buckle 210 and the second elastic buckle 220, a small setting space is formed between the first limiting plate 230 and the first elastic buckle 210 and between the first limiting plate 230 and the second elastic buckle 220, so as to facilitate the setting of the first locking portion 411 and the second locking portion 412, thereby preventing the first elastic buckle 210 and the second elastic buckle 220 from withdrawing from the first buckle groove 310 and the second buckle groove 320, and at this time, the required sizes of the first locking portion 411 and the second locking portion 412 are both small, and thus the required materials for making the first locking portion 411 and the second locking portion 412 are both less, thereby reducing the production cost, and at the same time, the first locking portion 411 and the second locking portion 412 are not easy to fall off from the small setting space. Of course, the reflector 200 may not be provided with the first limiting plate 230, that is, the first limiting plate 230 may not be provided between the first elastic buckle 210 and the second elastic buckle 220.

[0041] Optionally, the first locking portion 411 and the second locking portion 412 may be provided separately, that is, there is no connection relationship between the first locking portion 411 and the second locking portion 412 .

[0042] In another embodiment, the first locking portion 411 and the second locking portion 412 are connected to each other. Figure 7The retaining spring 400 is also provided with a second limiting plate 420 connecting the first locking portion 411 and the second locking portion 412. In order to prevent the first locking portion 411 and the second locking portion 412 from withdrawing from the setting space formed between the first limiting plate 230 and the first elastic buckle 210 and between the first limiting plate 230 and the second elastic buckle 220 in the vertical direction, a limiting hole 421 is provided on the second limiting plate 420, and an elastic limiting protrusion 231 is protruded on the first limiting plate 230. The elastic limiting protrusion 231 is deformable and can play a certain limiting role.

[0043] Specifically, when the face ring 300 is sleeved on the reflector 200 and the retaining spring 400 is respectively connected to the face ring 300 and the reflector 200, the limiting hole 421 can cooperate with the elastic limiting protrusion 231 in the vertical direction, that is, when the face ring 300 is sleeved on the reflector 200 and the retaining spring 400 is respectively connected to the face ring 300 and the reflector 200, the elastic limiting protrusion 231 can gradually extend into the limiting hole 421 to cooperate with the limiting hole 421 in the vertical direction, thereby preventing the second limiting plate 420 from moving in the vertical direction, and further preventing the second limiting plate 420 from driving the first locking portion 411 and the second locking portion 412 to exit the above-mentioned setting space in the vertical direction.

[0044] Optionally, in order to prevent the second limiting plate 420 from driving the first locking portion 411 and the second locking portion 412 to exit the above-mentioned setting space in a direction perpendicular to the direction of the axis of the face ring 300, please refer to Figure 5 , a third limiting plate 340 is protruded from the face ring 300, and the third limiting plate 340 is located in the notch 330. When the face ring 300 is sleeved on the reflector 200, and the retaining spring 400 is connected to the face ring 300 and the reflector 200 respectively, an installation space 500 is formed between the third limiting plate 340 and the first limiting plate 230. For details, please refer to Figure 6 .

[0045] During the specific assembly process, the second limit plate 420 can be inserted into the installation space 500, that is, the second limit plate 420 can be inserted into the installation space 500, and in the process of inserting into the installation space 500, the second limit plate 420 can contact the elastic limit protrusion 231. Since the elastic limit protrusion 231 itself can undergo elastic deformation, the elastic limit protrusion 231 is not easy to prevent the insertion of the second limit plate 420, and since the elastic limit protrusion 231 can cooperate with the limit hole 421 in the vertical direction, therefore, under the action of the elastic limit protrusion 231 and the limit hole 421, the second limit plate 420 is not easy to withdraw from the installation space 500.

[0046] At the same time, since the second limiting plate 420 can be respectively limited with the first limiting plate 230 and the third limiting plate 340 in the direction perpendicular to the direction of the axis of the face ring 300, that is, the first limiting plate 230 and the third limiting plate 340 can limit the movement of the second limiting plate 420 in the direction perpendicular to the direction of the axis of the face ring 300, this can prevent the second limiting plate 420 from exiting the installation space 500 in the direction perpendicular to the direction of the axis of the face ring 300, and further prevent the second limiting plate 420 from driving the first locking portion 411 and the second locking portion 412 to exit the above-mentioned setting space in the direction perpendicular to the direction of the axis of the face ring 300. Of course, the face ring 300 may not be provided with a protruding third limiting plate 340.

[0047] Optionally, refer to Figure 4 The first limiting plate 230 may be provided with a force unloading hole 232, that is, the first limiting plate 230 has an opening, the force unloading hole 232 is a strip hole, and the force unloading hole 232 has a first end 2321 and a second end 2322 arranged at intervals, the elastic limiting protrusion 231 may be arranged close to the force unloading hole 232, and the elastic limiting protrusion 231 may be deformably arranged in the force unloading hole 232. Since the elastic limiting protrusion 231 is arranged close to the force unloading hole 232, therefore, in the process of limiting cooperation between the elastic limiting protrusion 231 and the limiting hole 421, That is, after the elastic limiting protrusion 231 is subjected to the force applied by the second limiting plate 420, the elastic limiting protrusion 231 easily drives the structure around the force unloading hole 232 to deform, so that the deformation space of the elastic limiting protrusion 231 is larger, and the deformed elastic limiting protrusion 231 can enter the force unloading hole 232, thereby leaving a larger space to facilitate the installation of the second limiting plate 420, that is, to facilitate the insertion of the second limiting plate 420 into the installation space 500 and the limiting cooperation between the elastic limiting protrusion 231 and the limiting hole 421. Of course, the first limiting plate 230 may not be provided with the force unloading hole 232.

[0048] Optionally, the unloading hole 232 may extend in the horizontal direction, that is, the unloading hole 232 is a horizontal structure.

[0049] In another embodiment, please refer to Figure 4 and Figure 6, the unloading hole 232 is a V-shaped structure or a U-shaped structure, and the unloading hole 232 is arranged around the elastic limiting protrusion 231, which makes the distance between the first end 2321 and the second end 2322 closer, that is, the structure of the first limiting plate 230 between the first end 2321 and the second end 2322 is less, and thus the structure of the first limiting plate 230 at this location is more likely to deform, and because the unloading hole 232 is arranged around the elastic limiting protrusion 231, that is, the elastic limiting protrusion 231 can be located between the first end 2321 and the second end 2322, therefore, after the elastic limiting protrusion 231 is subjected to a force, the structure of the first limiting plate 230 between the first end 2321 and the second end 2322 can be more easily deformed along with the elastic limiting protrusion 231, thereby avoiding a larger space to facilitate the setting of the second limiting plate 420. Optionally, the unloading hole 232 can also be an irregular arc structure.

[0050] Optionally, the elastic limiting protrusion 231 has an end surface, which may be a top surface of the elastic limiting protrusion 231 , and the end surface may be a plane.

[0051] In another embodiment, please refer to Figure 4 At least a portion of the end face of the elastic limiting protrusion 231 is a guiding bevel, which makes it easier for the elastic limiting protrusion 231 to enter the limiting hole 421 to cooperate with the limiting hole 421, and since the guiding bevel can be set toward the lamp head assembly 100, during the process of inserting the second limiting plate 420 into the installation space 500, the second limiting plate 420 will contact the guiding bevel, and since the contact area between the second limiting plate 420 and the guiding bevel is larger, the second limiting plate 420 can drive the elastic limiting protrusion 231 to deform more easily and stably.

[0052] Optionally, the edge of the reflector 200 may not be provided with the avoidance opening 240 described below. When the face ring 300 is sleeved on the reflector 200, the third limit plate 340 is located at the edge of the reflector 200, which allows a larger distance between the first limit plate 230 and the third limit plate 340.

[0053] In another embodiment, please refer to Figure 4 The edge of the reflector 200 is provided with an escape opening 240, and the escape opening 240 is located between the first elastic buckle 210 and the second elastic buckle 220, please refer to Figure 6 When the face ring 300 is sleeved on the reflector 200, a part of the third limit plate 340 can be located in the avoidance opening 240, that is, at this time, in the circumferential direction of the face ring 300, the third limit plate 340 can cooperate with the avoidance opening 240 to limit the position. At the same time, in the process of the face ring 300 being sleeved on the reflector 200, the cooperation between the third limit plate 340 and the avoidance opening 240 can play a certain guiding installation role.

[0054] In this embodiment, since a portion of the third limiting plate 340 can be located within the avoidance opening 240, that is, at this time, the third limiting plate 340 is arranged closer to the first limiting plate 230, this makes the distance between the first limiting plate 230 and the third limiting plate 340 smaller, that is, the formed installation space 500 is smaller, and then the thickness of the second limiting plate 420 can be designed to be thinner, so as to reduce the production cost while reducing the overall weight of the lamp body assembly.

[0055] Optionally, the retaining spring 400 may include a support plate 430, a rotating shaft 440, a locking portion 410 and a second limit plate 420, and at least one of the support plate 430 and the second limit plate 420 may be rotatably disposed on the rotating shaft 440, so that the present application can flexibly adjust the rotational position of the second limit plate 420 relative to the support plate 430, so that the second limit plate 420 can more easily enter the installation space 500, and the support plate 430 can abut against the installation base in the vertical direction.

[0056] When the lamp body assembly is installed on the mounting base, a limit rod can be provided on the rotating shaft 440. When the support plate 430 and the second limit plate 420 move away from each other, at least one of the support plate 430 and the second limit plate 420 can contact the limit rod, that is, at least one of the support plate 430 and the second limit plate 420 can rotate to contact the limit rod, so that the one of the support plate 430 and the second limit plate 420 that contacts the limit rod stops rotating. At this time, in the vertical direction, the support plate 430 can be stably supported on the mounting base. When the assembly is removed from the mounting base, the operator can apply force to the lamp body assembly to move the support plate 430 away from the mounting base, and under the action of gravity, the support plate 430 can be close to the second limit plate 420, that is, at this time, the one of the support plate 430 and the second limit plate 420 that is in contact with the limit rod is away from the limit rod, so that the support plate 430 is close to the second limit plate 420, and then close to the face ring 300, so as to reduce the space occupied by the retaining spring 400 and the face ring 300 as a whole, thereby facilitating the operator to remove the lamp body assembly from the mounting base.

[0057] In another embodiment, please refer to Figure 7 and Figure 8In order to improve the efficiency of removing the lamp body assembly from the installation base, the clamping spring 400 may further include an elastic member 450, and the elastic member 450 elastically connects the support plate 430 and the second limiting plate 420, that is, the elastic member 450 can limit the rotation position of the second limiting plate 420 relative to the support plate 430, so that when the lamp body assembly is installed on the installation base, the second limiting plate 420 can apply a force to the support plate 430 through the elastic member 450, that is, at this time, the elastic member 450 is elastically deformed, so that the support plate 430 can be stably supported on the installation base. Correspondingly, when the lamp body assembly is removed from the mounting base, that is, when the support plate 430 is not in contact with the mounting base, the elastic member 450 begins to recover to its initial state, and during the resetting process of the elastic member 450, the elastic member 450 can apply a force to the support plate 430 to make the support plate 430 close to the second limit plate 420, and then close to the face ring 300, that is, under the elastic driving action of the elastic member 450 and the action of gravity, the support plate 430 approaches the face ring 300 faster, and thus the lamp body assembly is removed from the mounting base faster.

[0058] Optionally, the elastic member 450 may be a spring, and the spring elastically connects the support plate 430 and the second limiting plate 420 .

[0059] In another embodiment, after the second limit plate 420 is inserted into the installation space 500, other components are provided between the second limit plate 420 and the support plate 430, such as the third limit plate 340 mentioned above. In order to facilitate the setting of the elastic member 450, the elastic member 450 can be a torsion spring, which is sleeved on the rotating shaft 440, and one end of the torsion spring is connected to the support plate 430, and the other end of the torsion spring is connected to the second limit plate 420. The torsion spring can limit the angle range between the second limit plate 420 and the support plate 430. At the same time, when the support plate 430 is not in contact with the installation base, the torsion spring can play a reset role.

[0060] Optionally, the width of the first locking portion 411 at all locations may be consistent, and the width of the second locking portion 412 at all locations may also be consistent, that is, in the vertical upward direction, the width of the first locking portion 411 and the width of the second locking portion 412 may both remain unchanged.

[0061] In another embodiment, in the vertical upward direction, the width of at least one of the first locking portion 411 and the second locking portion 412 gradually increases. Since the side surface of the reflector 200 is a slope, this arrangement can adapt to the structure of the reflector 200.
