Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0049] When decorating a room, users usually choose suitable lamps, such as downlights, according to the decoration style of the room. The most important thing is that the appearance of the lamp shell matches the decoration style. The light-emitting surface of the shell of a conventional downlight has a flat surface ring and a stepped surface ring. Users can choose a shell with a specific appearance according to different decoration styles.

[0050] The shell of this type of lamp in the related art has a relatively simple appearance and limited application scenarios. At the same time, when the shell is damaged, it needs to be replaced as a whole, and the cost of repair and replacement is high.

[0051] In order to solve the above problems, an embodiment of the present application provides a lamp and a housing thereof. The lamp includes a housing 100 and a light source assembly 200 . The light source assembly 200 is disposed in the housing 100 .

[0052] The light source assembly 200 is used to provide lighting, and the user can select different light sources according to needs, which may be but are not limited to LED lights.

[0053] The above-mentioned lamp may be, but is not limited to, a downlight. The housing 100 of the lamp is described below by taking the housing of a downlight as an example.

[0054] like Figure 1 to Figure 5 , Figure 7 and Figure 12 to Figure 17As shown, the housing 100 of the lamp has a first assembly state and a second assembly state, and the housing 100 includes: a back shell module 10 and a face ring module 20, the back shell module 10 has a receiving cavity 103, the receiving cavity 103 is used to install the light source assembly 200, the outer surface of the back shell module 10 is provided with a first mounting portion 101 and a second mounting portion 102, the back shell module 10 includes a backlight end 1 and a first light output end 2; the face ring module 20 has a center hole 203, the center hole 20 3 is used for the back shell module 10 to extend into, the center hole 203 includes a light inlet end 3 and a second light outlet end 4, and the face ring module 20 is provided with a third mounting portion 201 and a fourth mounting portion 202; when the housing 100 is in the first position, the first mounting portion 101 is connected to the third mounting portion 201, the first light outlet end 2 is located in the center hole 203, the first light outlet end 2 is close to the second light outlet end 4, and the distance between the end face of the backlight end 1 and the end face of the second light outlet end 4 is the first distance H1( Figure 7 When the housing 100 is in the second position, the second mounting portion 102 is connected to the fourth mounting portion 202, the first light output end 2 is directly opposite to the light input end 3, and the distance between the end face of the backlight end 1 and the end face of the second light output end 4 is the second distance H2 ( Fig.16 The second distance H2 is greater than the first distance H1, so that the appearance of the housing 100 is different when it is in the first assembly state and when it is in the second assembly state.

[0055] The back shell module 10 serves to install the light source assembly 200. Usually, the light source assembly 200 is disposed in the accommodating cavity 103 of the back shell module 10. Specifically, the back shell module 10 includes a back shell 11 and a light-transmitting cover 12, and the back shell 11 and the light-transmitting cover 12 form the accommodating cavity 103. During the assembly process of the back shell module 10, the light source assembly 200 is first fixed in the back shell 11, and then the light-transmitting cover 12 is assembled, and the light emitted by the light source assembly 200 is emitted to the outside of the back shell module 10 through the light-transmitting cover 12.

[0056] The first mounting portion 101 and the third mounting portion 201 are connected correspondingly, and the second mounting portion 102 and the fourth mounting portion 202 are connected correspondingly, so that the face ring module 20 and the back shell module 10 are assembled and connected together, so that the shell 100 is in different assembly states, thereby achieving different appearances. Through the above design, the shell 100 is modularly assembled, that is, during the assembly process of the shell 100, the face ring module 20 and the back shell module 10 can be assembled separately first, and then the two can be assembled together. In this way, not only is the assembly process of the shell 100 simplified, but also, when the back shell module 10 or the face ring module 20 is damaged, only one of them can be replaced, and the other does not need to be replaced, thus reducing the maintenance cost.

[0057] The above-mentioned light source assembly 200 is usually close to the backlight end 1 of the back shell module 10. Regardless of whether the shell 100 is in the first assembly state or the second assembly state, the second light output end 4 of the face ring module 20 is the final light output end of the shell 100. Usually, when the shell 100 is installed, the backlight end 1 extends into the deepest part of the wall, and the second light output end 4 is in contact with the wall to cover the installation hole for installing the lamp on the wall. In other words, the distance between the end face of the backlight end 1 and the end face of the second light output end 4 is the overall thickness of the appearance of the shell 100. The thickness direction of the back shell module 10 refers to the axial direction of the shell 100.

[0058] like Figure 2 and Figure 7 As shown, when the housing 100 is in the first assembly state, a portion of the structure of the back housing module 10 close to the first light output end 2 is located in the central hole 203 of the face ring module 20, and the face ring module 20 covers a portion of the structure of the back housing module 10 close to the first light output end 2, that is, the end face of the first light output end 2 can be flush with the end face of the second light output end 4. At this time, the housing 100 has a planar face ring appearance, and the appearance structure of the housing 100 is as shown in FIG. Figure 2 Of course, when the housing 100 is in the first assembly state, the end face of the first light output end 2 may also have a preset distance with the end face of the second light output end 4 of the face ring module 20, that is, the end face of the first light output end 2 may also move inward from the end face of the second light output end 4 of the face ring module 20 by a preset distance, so that part of the hole wall of the center hole 203 of the face ring module 20 close to the second light output end 4 is exposed.

[0059] like Figure 3 Fig.14 and Fig.16 As shown, when the housing 100 is in the second assembly state, the end face of the first light output end 2 abuts against the end face of the light input end 3. At this time, the hole wall of the central hole 203 of the face ring module 20 is completely exposed, and the housing 100 has a stepped face ring appearance. The appearance structure of the housing 100 is as shown in FIG. Figure 3Usually, for aesthetic purposes, a plurality of ridges 24 are provided on the hole wall of the central hole 203 of the face ring module 20, the ridges 24 extending along the circumference of the face ring module 20, and the plurality of ridges 24 are arranged in a stepped manner, and the aforementioned stepped face ring refers to the appearance state of the shell 100 in which the user can see the plurality of ridges 24 of the face ring module 20 when the shell 100 is in the second assembly state. The housing 100 of the lamp provided in the embodiment of the present application, the outer surface of the back shell module 10 is provided with a first mounting portion 101 and a second mounting portion 102, the face ring module 20 is provided with a third mounting portion 201 and a fourth mounting portion 202, when the back shell module 10 and the face ring module 20 are connected by the first mounting portion 101 and the third mounting portion 201, the housing 100 is in a first assembly state, at this time, the distance between the end face of the backlight end 1 of the back shell module 10 and the end face of the second light output end 4 of the face ring module 20 is H1, and the overall thickness of the appearance of the housing 100 is the first thickness; when the back shell module 10 and the face ring module 20 are connected by the second mounting portion 102 and the fourth mounting portion 202, the housing 100 is in a first assembly state. 100 is in the second assembly state. At this time, the distance between the end face of the backlight end 1 of the back shell module 10 and the end face of the second light output end 4 of the face ring module 20 is H2. In this way, the user can select different connection positions according to needs, so that the shell 100 has different assembly states, and the application range is relatively wide. At the same time, when the position of the light source component 200 in the accommodating cavity 103 does not change, since H2>H1, the user can select different connection methods, so that the distance between the light source component 200 and the end face of the second light output end 4 of the face ring module 20 changes, so that the appearance of the shell 100 is different when it is in the first assembly state and the second assembly state.

[0060] The assembly process of the back shell module 10 and the face ring module 20 in the housing 100 is as follows:

[0061] The back shell module 10 in the housing 100 is located below the face ring module 20, that is, the backlight end 1 of the back shell module 10 is close to the second light output end 4 of the face ring module 20. Fig.10 As shown; the back shell module 10 is assembled with the face ring module 20 from bottom to top, and this assembly process is called bottom installation.

[0062] Specifically, the size of the backlight end 1 of the back shell module 10 in a cross section perpendicular to the axis of the back shell module 10 needs to be smaller than the aperture of the second light output end 4 of the center hole 203, so that the backlight end 1 of the back shell module 10 can extend from the second light output end 4; the aperture of the second light output end 4 of the center hole 203 must be able to allow the first light output end 2 of the back shell module 10 to enter, and at the same time, the aperture of the light input end 3 of the center hole 203 cannot allow the first light output end 2 of the back shell module 10 to pass through, so that when the backlight end 1 of the back shell module 10 extends upward from the second light output end 4 of the face ring module 20 into the center hole 203, the first light output end 2 is stopped at the light input end 3 of the center hole 203.

[0063] The process of installing the housing 100 is as follows: the backlight end 1 of the back housing module 10 is extended upward from the second light-emitting end 4 of the face ring module 20 into the center hole 203 until the first mounting portion 101 on the back housing module 10 is connected to the third mounting portion 201 on the face ring module 20. At this time, the first light-emitting end 2 of the back housing module 10 is stopped at the light-incoming end 3 of the center hole 203, and the housing 100 is in the first assembly state. The appearance of the assembled housing 100 is as follows: Figure 2 and Figure 7 shown.

[0064] The back shell module 10 in the housing 100 is located above the face ring module 20, that is, the first light output end 2 of the back shell module 10 is close to the light input end 3 of the face ring module 20. Fig.16 As shown; the back shell module 10 is assembled with the face ring module 20 from top to bottom, and this assembly process is called top loading.

[0065] Specifically, the size of the first light output end 2 of the back shell module 10 in a cross section perpendicular to the axis of the back shell module 10 is larger than the diameter of the light input end of the center hole 203, so that when the first light output end 2 of the back shell module 10 approaches the face ring module 20 downward, the first light output end 2 can only stop at the light input end 3 and cannot extend into the center hole 203.

[0066] The process of installing the housing 100 is as follows: the first light-emitting end 2 of the back housing module 10 is opposite to the center hole 203, and the face ring module 20 moves upward until the fourth mounting portion 202 on the face ring module 20 is connected to the second mounting portion 102 on the back housing module 10. At this time, the first light-emitting end 2 of the back housing module 10 is abutted against the light-incoming end 3, so that the housing 100 is in the second assembly state. The appearance of the assembled housing 100 is as follows: Figure 3 and Fig.14 shown.

[0067] When the position of the light source assembly 200 in the accommodating cavity 103 does not change, since H2>H1, the user can choose different connection methods to change the distance between the light source assembly 200 and the end face of the second light output end 4 of the face ring module 20. When the light source assembly 200 is located on the inner wall of the accommodating cavity 103 close to the backlight end 1 and the housing 100 is in the first assembly state, the light emitted by the light source assembly 200 is as follows: Fig.12 When the housing 100 is in the second assembly state, the light source assembly 200 emits light as shown in FIG. Fig.17 As shown; thereby, the light emitting angles of the light source assembly 200 are different when the housing 100 is in the first assembly state and the second assembly state, so as to be suitable for different lighting scene requirements.

[0068] Of course, when the position of the light source assembly 200 in the back shell module 10 can be changed, the user can also adjust the position of the light source assembly 200 in the back shell module 10 according to the assembly state of the outer shell 100, so that the distance between the light source assembly 200 and the end face of the second light emitting end 4 is equal, that is, regardless of whether the outer shell 100 is in the first assembly state or the second assembly state, the light emitting angle of the light source assembly 200 is the same.

[0069] In summary, the housing 100 of the lamp of the present application achieves the purpose of taking into account a variety of appearances, a wide range of application scenarios and low maintenance costs.

[0070] like Figure 1 , Figure 7 and Figure 8 As shown, in some embodiments, the back shell 11 is cylindrical, and the back shell 11 has a closed end and an open end, the closed end is the backlight end 1, and the open end is the first light output end 2, and the light-transmitting cover 12 is arranged on the first light output end 2 to form a accommodating cavity 103; in the thickness direction of the back shell module 10, the cross-sectional area of ​​the backlight end 1 is smaller than the cross-sectional area of ​​the first light output end 2, the second mounting portion 102 is close to the first light output end 2, and the first mounting portion 101 is close to the backlight end 1, and in the thickness direction of the back shell module 10, the fourth mounting portion 202 is located on the side of the third mounting portion 201 close to the light input end 3.

[0071] The back shell 11 is used to install the light source assembly 200. Since the light source assembly 200 will emit a lot of heat during the lighting process, the back shell 11 can be made of metal materials such as aluminum to facilitate heat dissipation. Of course, the back shell 11 can also be made of materials such as plastic to reduce the overall weight of the back shell module 10.

[0072] By placing the second mounting portion 102 close to the first light emitting end 2 and the first mounting portion 101 close to the backlight end 1, that is, in the thickness direction of the back shell module 10, the first mounting portion 101 and the second mounting portion 102 are located on different planes of the back shell module 10 (planes perpendicular to the thickness direction of the back shell module 10). In this way, during the disassembly and assembly of the back shell module 10 and the face ring module 20, the probability of mutual influence between the first mounting portion 101 and the second mounting portion 102 is reduced. This is not only beneficial to improving the overall reliability of the back shell module 10, but also increases the difference between H2 and H1, thereby facilitating the expansion of the light emission angle range of the light source assembly 200 of the lamp.

[0073] like Figure 4 and Figure 7 As shown, the back shell 11 includes a backlight segment 111 and a light-emitting segment 112. The backlight segment 111 is cylindrical, and the light-emitting segment 112 is flared. The backlight segment 111 is connected to the small end of the light-emitting segment 112; the first mounting portion 101 is connected to one end of the backlight segment 111 close to the light-emitting segment 112, and the second mounting portion 102 is connected to the light-emitting segment 112; the direction from the light-input end 3 to the second light-emitting end 4 ( Figure 4 In the direction from top to bottom), the diameter of the center hole 203 gradually increases, that is, the diameter of the center hole 203 is the smallest near the light input end 3, and the diameter of the center hole 203 is the largest near the second light output end 4. The maximum diameter of the center hole 203 is larger than the outer diameter of the backlight segment 111, and the minimum diameter of the center hole 203 is smaller than the minimum diameter of the light output segment 112.

[0074] The above-mentioned flared shape can also be called a trumpet mouth, that is, it has a large mouth end and a small mouth end, and the small mouth end is close to the backlight end 1, and the large mouth end is close to the second light output end 4.

[0075] The light emitting section 112 is in a flared shape, the center hole 203 is a flared circular hole, and the inclination direction of the side wall of the light emitting section 112 is the same as the inclination direction of the inner wall of the center hole 203. The same inclination direction means that the inclination angle of the side wall of the light emitting section 112 is equal to or nearly equal to the inclination of the inner wall of the center hole 203. In this way, when the housing 100 is in the first assembly state, the side wall of the light emitting section 112 is relatively close to the inner wall of the center hole 203, so that not only can the light output of the light source assembly 200 be maximized, but also the back shell 11 and the face ring module 20 are firmly connected.

[0076] Through the above arrangement, the volume of the back shell 11 is reduced without affecting the light output of the light source assembly 200. In this way, not only the installation space of the lamp is reduced, but also the diameter of the center hole 203 is reduced. Therefore, the lamp can achieve the purpose of reducing the overall volume of the outer shell 100 while meeting the lighting requirements.

[0077] When the light source assembly 200 is installed, the light source assembly 220 can be installed not only in the backlight segment 111, but also on the bottom wall of the backlight segment 111, that is, on the inner wall of the accommodating cavity 103 close to the backlight end 1. Fig.12 The light source assembly 200 may also be installed on the inner side wall of the light emitting section 112, so that the light emitted by the light source assembly 200 is directly emitted from the first light emitting end 2, or the light source assembly 200 may also be installed on the side wall of the backlight section 111, and the light emitted by the light source assembly 11 is reflected to the first light emitting end 2 by a reflective element and emitted from the first light emitting end 2, which is not specifically limited here.

[0078] like Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, a first flange is provided on the edge of the small end of the center hole 203, and the first flange is the third mounting part 201. The third mounting part 201 is annular, and the inner diameter of the third mounting part 201 is smaller than the minimum diameter of the center hole 203; an elastic arm is provided on the outer surface of the backlight segment 111, and the elastic arm is the first mounting part 101. The free end of the first mounting part 101 can move between a first position and a second position under the action of an external force, and when the free end of the first mounting part 101 is in the first position, the backlight segment 111 can pass through the center hole 203; when the free end of the first mounting part 101 is in the second position, it abuts against the third mounting part 201 to limit the relative movement of the back shell 11 and the face ring module 20.

[0079] The elastic arm is a convex block that can be deformed and protrude from the outer wall of the backlight segment 111. The elastic arm can move toward the outer wall of the backlight segment 111 under the action of external force. One end of the first mounting portion 101 connected to the backlight segment 111 is a fixed end, and the other end is a free end. In other words, the free end of the first mounting portion 101 can move under the action of external force to approach or move away from the outer wall of the backlight segment 111. When the free end of the first mounting portion 101 is in the first position, the free end of the first mounting portion 101 fits with the outer wall of the backlight segment 111 or even is located inside the outer wall, so that the backlight segment 111 can pass through the center hole 203; after the backlight segment 111 passes through the center hole 203, the free end of the first mounting portion 101 moves to the second position in the direction away from the outer wall of the backlight segment 111 under the action of its own elastic force. At this time, the first mounting portion 101 abuts against the third mounting portion 201, so that the back shell 11 and the face ring module 20 are relatively fixed. At the same time, the first mounting portion 101 can be in the first position under the action of an external force, thereby realizing the separation of the first mounting portion 101 from the third mounting portion 201 .

[0080] With the above settings, the user can assemble the front ring module 20 and the back shell module 10 without the aid of tools, improving the assembly and installation efficiency of the housing 100 and facilitating disassembly by the user.

[0081] In one embodiment, the third mounting portion 201 connected to the small-mouth end of the central hole 203 can be annular, that is, covering the entire edge of the central hole 203 along the circumferential direction of the central hole 203. In this way, not only is the connection strength between the third mounting portion 201 and the central hole 203 improved, but also the third mounting portion 201 is not restricted by the number and position of the first mounting portions 101.

[0082] In order to make the connection between the front ring module 20 and the back shell module 10 firm when the housing 100 is in the first assembly state, in one embodiment, the number of the first mounting portions 101 can be multiple, and the multiple first mounting portions 101 are arranged along the circumferential direction of the back shell 11. In this way, when the front ring module 20 and the back shell module 10 are assembled, the multiple first mountings are connected to the third mounting portion 201, further improving the connection strength between the front ring module 20 and the back shell module 10.

[0083] In addition, in another embodiment, the third mounting portion 201 can also be provided only at the position corresponding to the first mounting portion 101. At this time, the number of the third mounting portions 201 can be less than or equal to the number of the first mounting portions 101, as long as it is ensured that the first mounting portion 101 and the third mounting portion 201 can be connected.

[0084] It should be noted that the above first mounting portion 101 can be integrally formed with the back shell 11. In this way, not only can the strength and reliability of the back shell module 10 be further improved, but also the assembly process is reduced. When the back shell 11 is made of plastic, the back shell 11 and the first mounting portion 101 can be integrally formed by injection molding or adhesively fixed, and when the back shell 11 is made of aluminum, the back shell 11 and the first mounting portion 101 can be integrally formed by die-casting or welded and fixed.

[0085] The above third mounting portion 201 can be integrally formed with the front ring module 20. In this way, not only can the strength and reliability of the front ring module 20 be further improved, but also the assembly process is reduced. The above front ring module 20 is usually made of plastic or metal. When the front ring module 20 is made of plastic, the front ring module 20 and the third mounting portion 201 can be integrally formed by injection molding or adhesively fixed, and when the front ring module 20 is made of metal, the front ring module 20 and the third mounting portion 201 can be integrally formed by die-casting or welded and fixed.

[0086] Secondly, in addition to the detachable connection between the first mounting part 101 and the third mounting part 201 using the above-mentioned flange and elastic arm structure, the above-mentioned first mounting part 101 and the third mounting part 201 can also be screwed together by fasteners to achieve the detachable connection between the first mounting part 101 and the third mounting part 201, and the disassembly and assembly of the instant noodle ring module 20 and the back shell module 10.

[0087] In addition, when necessary, the first mounting portion 101 and the third mounting portion 201 may also be fixedly connected by snap connection or screw connection, which is not specifically limited here.

[0088] like Figure 4 , Figure 5 , Figure 8 and Fig.16 As shown, in some embodiments, the first light emitting end 2 is provided with a second flange, the second flange is the second mounting portion 102, and the second mounting portion 102 is formed by extending outward from the edge of the first light emitting end 2; the face ring module 20 includes an inner ring and an outer ring, the inner ring has a center hole 203, the outer ring is connected to the outer side wall of the inner ring, and the end of the inner hole of the outer ring close to the light input end 3 can be inserted by the first light emitting end 2, and the edge of the inner hole of the outer ring close to the light input end 3 is provided with a hook, and the hook connected to the outer ring is the fourth mounting portion 202.

[0089] The second mounting portion 102 may be an integral structure with the back shell 11 , or the second mounting portion 102 may be a separate structure with the back shell 11 .

[0090] The fourth mounting portion 202 may also be an integral structure or a separate structure with the outer ring.

[0091] Through the above-mentioned arrangement, when the light-emitting section 112 of the back shell 11 is extended into the center of the outer ring of the face ring module 20, the second mounting portion 102 is engaged with the fourth mounting portion 202. In this way, the user can assemble the face ring module 20 and the back shell module 10 together without the aid of tools, thereby improving the assembly and installation efficiency of the outer shell 100. At the same time, the face ring module 20 and the back shell module 10 are firmly connected. Moreover, the user can also squeeze the second mounting portion 102 or move the fourth mounting portion 202 outward to separate the second mounting portion 102 from the fourth mounting portion 202, thereby separating the face ring module 20 from the back shell module 10, which is convenient for the user to disassemble.

[0092] It should be noted that, in addition to the above-mentioned flange and hook structure to achieve detachable connection between the second mounting part 102 and the fourth mounting part 202, the above-mentioned second mounting part 102 and the fourth mounting part 202 can also be screwed together by fasteners to achieve detachable connection between the second mounting part 102 and the fourth mounting part 202, and disassembly and assembly of the instant noodle ring module 20 and the back shell module 10.

[0093] In addition, when necessary, the second mounting portion 102 and the fourth mounting portion 202 may also be fixedly connected by snap connection or screw connection, which is not specifically limited here.

[0094] like Figure 8 As shown, in some embodiments, the outer ring is a hollow cylindrical structure, the inner ring is a hollow truncated cone structure, the central through hole of the inner ring is the central hole 203, there is a cavity between the inner ring and the outer ring, the large mouth end of the inner ring is the light input end 3, the small mouth end of the inner ring is the second light output end 4, the inner diameter of the outer ring is equal to the maximum outer diameter of the inner ring, and the outer diameter of the inner ring gradually increases from the light input end 3 to the second light output end 4.

[0095] There is a cavity between the inner ring and the outer ring, so that the face ring module 20 and the back shell module 10 are firmly connected and easy to assemble and disassemble, while reducing the weight of the face ring module 20.

[0096] It should be noted that, in the thickness direction of the back shell module 10, when the length of the inner ring is greater than the length of the light emitting section 112, when the housing 100 is in the first assembly state, the end face of the first light emitting end 2 is located inside the end face of the second light emitting end 4, and at this time, the hole wall portion of the center hole 203 is exposed. When the length of the inner ring is equal to the length of the light emitting section 112, when the housing 100 is in the first assembly state, the end face of the first light emitting end 2 is flush with the end face of the second light emitting end 4, and at this time, the housing 100 has a planar face ring.

[0097] like Figure 5 , Figure 7 and Figure 8 As shown, a face ring flange is extended outwardly from the connection between the outer ring and the inner ring, and the face ring flange surface is the second light output end 4. The face ring flange plays a decorative role.

[0098] The inner ring, the outer ring and the face ring flange may be an integral structure, which not only improves the strength of the face ring module 20 and is beneficial to improving the reliability of the housing 100, but also simplifies the assembly process.

[0099] In order to ensure that the face ring module 20 is firmly connected to the back shell module 10 when the outer shell 100 is in the second assembly state, in one embodiment, the second mounting portion 102 is annular, that is, it completely covers the edge of the first light emitting end 2 along the light emitting section 112. In this way, not only the connection strength between the second mounting portion 102 and the first mounting portion 101 is improved, but also the second mounting portion 102 is not limited by the number and position of the fourth mounting portion 202.

[0100] In order to further make the connection between the face ring module 20 and the back shell module 10 more firmly when the outer shell 100 is in the second assembly state, the number of the above-mentioned fourth mounting parts 202 can be multiple, and the multiple fourth mounting parts 202 are arranged along the circumference of the outer ring. In this way, when the face ring module 20 and the back shell module 10 are assembled, the multiple fourth mounting parts are connected to the second mounting parts 102, which further improves the connection firmness between the face ring module 20 and the back shell module 10.

[0101] In addition, in another embodiment, the second mounting portion 102 may be provided only at the position corresponding to the fourth mounting portion 202. In this case, the number of the second mounting portions 102 may be less than or equal to the number of the fourth mounting portions 202, as long as the fourth mounting portion 202 and the second mounting portion 102 can be connected.

[0102] like Figure 5 and Figure 8 As shown, in some embodiments, the user may not set the ridge 24 or set a wavy microstructure on the hole wall of the central hole 203. On the one hand, the aesthetics of the lamp can be improved, and on the other hand, the above microstructure can reflect light, that is, diffuse reflection, so that the light of the lamp is more uniform.

[0103] In order to improve the light extraction efficiency, a reflective layer can be provided on the surface of the ridge 24 or the inner wall of the center hole 203 to reflect the light emitted from the light source assembly 200 to the inner wall of the center hole 203 to be emitted to the first light output end 2, thereby improving the light extraction rate of the light source assembly 200.

[0104] The above-mentioned reflective layer can also be a reflective film layer or the ridges 24 can be made of reflective material.

[0105] like Figure 1 and Figure 8 As shown, in some embodiments, a first clamping portion 104 is provided on the inner surface of the back shell module 10, that is, a first clamping portion 104 is provided on the inner side wall of the accommodating cavity 103, and a second clamping portion 123 is provided on the light-transmitting cover 12, and the first clamping portion 104 and the second clamping portion 123 are detachably connected. In this way, the light-transmitting cover 12 and the back shell 11 can be assembled and disassembled, thereby improving the assembly and maintenance efficiency.

[0106] like Figure 8 As shown, the light-transmitting cover 12 includes a light-transmitting plate 121 and a connecting tube 122, the connecting tube 122 is connected to one side of the light-transmitting plate 121, the edge of the connecting tube 122 away from the light-transmitting plate 121 is connected to the second clamping portion 123, the second clamping portion 123 is a hook, and in the thickness direction of the back shell module 10, the first clamping portion 104 is located between the first mounting portion 101 and the second mounting portion 102; the first clamping portion 104 is a recess.

[0107] The light-transmitting plate 121 may be, but is not limited to, a diffusion plate.

[0108] Through the above arrangement, the light cover 12 and the back shell 11 can be detachably connected, and the light cover 12 and the back shell 11 can be installed and removed without the aid of tools, which improves the strength of the light cover 12 and is conducive to improving the reliability of the back shell module 10.

[0109] It should be noted that, in addition to being designed to be engaged with a hook and an elastic arm to achieve a detachable connection between the light-transmitting plate 121 and the connecting tube 122, the first clamping portion 104 and the second clamping portion 123 can also be designed to be engaged with a hook and a recess, or the first clamping portion 104 and the second clamping portion 123 can also be designed to be engaged with a hook and an elastic arm structure.

[0110] In order to improve the firmness of the connection between the light-transmitting cover 12 and the back shell 11 , there may be a plurality of second clamping portions 123 , which are arranged along the circumference of the connecting tube 122 .

[0111] In order to facilitate the installation of the housing 100 and the target object, as Figure 1 to Figure 3 As shown, in some embodiments, the face ring module 20 is provided with a connecting column 25 and an elastic member 30, and the elastic member 30 is fixed to the face ring module 20 through the connecting column 25, and the elastic member 30 is used to fix the face ring module 20 on the target object.

[0112] The target object may be, but is not limited to, a wall.

[0113] The connecting column 25 is provided with an installation opening for installing the elastic member 30 . The structure of the installation opening is designed according to the structure of the elastic member 30 and is not specifically limited here.

[0114] The elastic member 30 may be a spring or a spring sheet. The spring may be a herringbone spring or a conventional spring.

[0115] Through the above arrangement, the housing 100 of the lamp can be installed on the target object without tools, which is convenient for installation. Moreover, after the housing 100 of the lamp is installed on the target object, the elastic member 30 can also give elastic force to the target object, so that the two are firmly connected, reducing the risk of the lamp falling off.

[0116] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
