[0002] Existing lighting fixtures are not conducive to installation. Summary of the Invention

[0003] This application provides a lighting fixture that is easy to install.

[0004] This application provides a lamp, wherein at least one light-emitting component includes a light-emitting body and a first electrical connection terminal and a second electrical connection terminal electrically connected to the light-emitting body; At least one outer lamp cover includes a main body and at least two connecting parts, the at least two connecting parts include a first connecting part and a second connecting part, and an outer connecting structure is provided on the outer side of any connecting part; Each lamp holder includes a first base and a second base, which are spaced apart, with the first base located outside the second base; the inner side of the first base of each lamp holder is provided with an inner connecting structure, and the inner connecting structure and the outer connecting structure can be rotated relative to each other to connect or separate. At least two lamp holders connect a light-emitting component and an outer lamp cover, and the at least two lamp holders connecting the light-emitting component and the outer lamp cover include a first lamp holder and a second lamp holder; The first lamp holder is connected to the first base body and the first connecting part. The second base body of the first lamp holder is provided with a third electrical connection terminal. The third electrical connection terminal and the first electrical connection terminal can be inserted and connected together by rotating relative to each other around the same axis to achieve physical and electrical connection. The first body and the second connecting part of the second lamp holder are connected. The second body of the second lamp holder is provided with a fourth electrical connection terminal. The fourth electrical connection terminal and the second electrical connection terminal can be inserted and connected together by rotating relative to each other around the same axis to achieve physical and electrical connection. During the relative rotation of the inner connecting structure of the first lamp holder and the outer connecting structure of the first connecting part, the third electrical connecting terminal and the first electrical connecting terminal may simultaneously rotate relative to each other or remain relatively stationary; and / or, During the relative rotation of the inner connection structure of the second lamp holder and the outer connection structure of the second connection part, the fourth electrical connection terminal and the second electrical connection terminal may rotate relative to each other or not rotate relative to each other.

[0005] Beneficial effects: In the embodiments of this application, a lamp holder in the lamp can be connected to the outer lamp cover and the light-emitting component, which makes it convenient for users to install lamps in various scenarios such as outdoors. Compared with the multiple connections of too many structural components in the lamp, it is more conducive to the installation of lamps.

[0006] Furthermore, any lamp holder in the lamp fixture of this application embodiment can be provided with an electrical connection terminal. The electrical connection terminal on the lamp holder can be physically and electrically connected with the electrical connection component of the light-emitting component. Thus, in this application embodiment, a lamp holder can achieve a physical connection with the outer lamp cover and a physical and electrical connection with the electrical connection terminal of the light-emitting component. Compared with the prior art, which designs physical connection structure and electrical connection structure separately, this application embodiment can simplify the structure of the lamp fixture and simplify the installation process of the lamp fixture.

[0007] Furthermore, in any embodiment of this application, the outer seat of any lamp holder, such as the first seat, is connected to the outer side of one of the connecting parts of the outer lamp cover. The space between the inner and outer seats of any lamp holder can accommodate one of the connecting parts of the outer lamp cover. The inner and outer seats of any lamp holder restrict one of the connecting parts of the outer lamp cover between them. Thus, compared with the single positional relationship of the two components, the connection between the lamp holder and the outer lamp cover in this embodiment of the application can improve the waterproof performance at the connection point.

Detailed Implementation

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0043] In this document, references to "embodiment" or "implementation" mean that a particular feature, structure, or characteristic described in connection with an embodiment or implementation may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0044] like Figures 1 to 15 As shown, the lamp 10A includes at least one outer lampshade 400A, at least one light-emitting component 300A, and at least two lamp holders (100A, 200B). For example, the lamp 10A includes M outer lampshades 400A, M light-emitting components 300A, and 2M lamp holders (100A, 200B), where M is an integer greater than or equal to 1, and M can be an integer such as 1, 2, 3, 4, 5, 6, 10, etc. The number of M can be set according to requirements, and this embodiment does not limit the value of M. 2M is 2*M, that is, the sum of two M's. When M=1, the lamp 10A includes one outer lampshade 400A, one light-emitting component 300A, and two lamp holders (100A, 200B). In this embodiment, the lamp 10A with M=1 can be understood as a single light-emitting device. When M≥2, luminaire 10A includes at least two outer lampshades 400A, at least two light-emitting components 300A, and at least four lamp holders (100A, 200B). In this embodiment, luminaire 10A with M≥2 can be understood as a series-connected light string structure. It is understood that a series-connected light string structure can include at least two individual light-emitting devices, with physical and electrical connections between adjacent light-emitting devices in the series-connected light string structure. For example, the physical connection between two adjacent light-emitting devices in the series-connected light string structure includes the physical connection of the lamp holders between them. For example, the electrical connection between two adjacent light-emitting devices in the series-connected light string structure includes the electrical connection of the light-emitting elements between them.

[0045] For example, at least one light-emitting component 300A includes a light-emitting element 330A and a first electrical connection terminal 310 and a second electrical connection terminal 320 electrically connected to the light-emitting element 330A. It is understood that the number of electrical connection terminals of the light-emitting component 300A in this embodiment is not limited to the first electrical connection terminal 310 and the second electrical connection terminal 320; other electrical connection terminals may also be included, which will not be listed here. Specifically, the light-emitting element 330A is capable of emitting light. In one optional embodiment of this application, the light-emitting element 330A may include a single component, such as a light-emitting component, to achieve light emission. In another optional embodiment of this application, the light-emitting element 330A may include at least two components, such as a carrier and a light-emitting component electrically connected to the carrier. The light-emitting component disposed on the carrier may be one or more. In one optional embodiment of this application, the light-emitting component of the light-emitting body 330A is indirectly electrically connected to the first electrical connection terminal 310 and the second electrical connection terminal 320. For example, the carrier of the light-emitting body 330A is electrically connected to the first electrical connection terminal 310 and the second electrical connection terminal 320, that is, the light-emitting component of the light-emitting body 330A is electrically connected to the first electrical connection terminal 310 and the second electrical connection terminal 320 through the carrier of the light-emitting body 330A. In another optional embodiment of this application, the light-emitting component of the light-emitting body 330A is directly electrically connected to the first electrical connection terminal 310 and the second electrical connection terminal 320. For example, the light-emitting component of the light-emitting body 330A is directly electrically connected to the first electrical connection terminal 310 and the second electrical connection terminal 320. (Refer to the following...) Figure 15 The light-emitting component 300A in one optional embodiment of this application will be described by way of example, and then the light-emitting components in other optional embodiments of this application will be described by way of example with reference to other figures.

[0046] like Figure 15As shown, the light-emitting element 330A of the light-emitting component 300A includes a carrier 331A and a light-emitting component 332 electrically connected to the carrier 331A. Exemplarily, the carrier 331A may be a rigid circuit board 331A, and the light-emitting component 332 is disposed on the rigid circuit board 331A and electrically connected to the circuitry of the rigid circuit board 331A. The rigid circuit board 331A may include a first end 3301, a second end 3302, a first side portion 3303, and a second side portion 3304. The first end 3301 and the second end 3302 are disposed opposite to each other, and the first side portion 3303 and the second side portion 3304 are disposed opposite to each other. The first end 3301 and the second end 3302 are opposite ends of the rigid circuit board 331A, and the first side portion 3303 and the second side portion 3304 are opposite sides of the rigid circuit board 331A. Exemplarily, there may be one or more light-emitting components 332; for example, in this embodiment, there are multiple light-emitting components 332. The light-emitting component 332 is, for example, an LED light-emitting element. In one optional embodiment, at least one light-emitting component 332 is disposed on one side of the carrier 331A. In another optional embodiment, at least one light-emitting component 332 is disposed on one side of the carrier 331A, and at least one light-emitting component 332 is disposed on the other side of the carrier 332A. Exemplarily, the rigid circuit board 331A can be one or more flat substrate structures. When the rigid circuit board 331A includes multiple flat substrate structures, the various flat substrate structures are interconnected to form an interlaced structure, such as a cross-shaped interlaced structure.

[0047] Both the first electrical connection terminal 310 and the second electrical connection terminal 320 are electrically connected to the circuitry of the carrier 331A, such as the rigid circuit board 331A, thereby achieving electrical connection between both the first electrical connection terminal 310 and the second electrical connection terminal 320 and the light-emitting component 332 disposed on the rigid circuit board 311A. In an optional embodiment, the first electrical connection terminal 310 is disposed at the first end 3301 of the rigid circuit board 331A and electrically connected to the circuitry at the first end 3301 of the rigid circuit board 331A; the second electrical connection terminal 320 is disposed at the second end 3302 of the rigid circuit board 331A and electrically connected to the circuitry at the second end 3302 of the rigid circuit board 331A. It should be noted that the embodiments of this application do not limit the location of the first electrical connection terminal 310 and the second electrical connection terminal 320 on the rigid circuit board 331A; for example, the first electrical connection terminal 310 may be disposed on the first side 3303, and the second electrical connection terminal 320 may be disposed on the second side 3304. For example, the first electrical connection terminal 310 and the second electrical connection terminal 320 are located at opposite ends or opposite sides of the light-emitting body 330A. Specifically, the first electrical connection terminal 310 and the second electrical connection terminal 320 are located at opposite ends or opposite sides of the rigid circuit board 331A in the light-emitting body 330A.

[0048] For example, the first electrical connection terminal 310 and the second electrical connection terminal 320 are symmetrically arranged with respect to the light-emitting element 330A. Specifically, the first electrical connection terminal 310 and the second electrical connection terminal 320 are symmetrically arranged with respect to the rigid circuit board 331A in the light-emitting element 330A.

[0049] For example, the first electrical connection terminal 310 and the second electrical connection terminal 320 are coaxially arranged, such as... Figure 5 , Figure 7 , Figure 8 , Figure 9 and Figure 15 As shown, the first electrical connection terminal 310 and the second electrical connection terminal 320 both have the same axis P1. In other alternative embodiments, the first electrical connection terminal 310 and the second electrical connection terminal 320 are not coaxially arranged; for example, the axes of the first electrical connection terminal 310 and the second electrical connection terminal 320 are parallel or intersecting.

[0050] For example, at least one outer lampshade 400A includes a main body 430A and at least two connecting portions (410, 420). The at least two connecting portions (410, 420) include a first connecting portion 410 and a second connecting portion 420. The outer surface of any connecting portion (410, 420) is provided with an external connecting structure (411, 421). Specifically, the outer surface of the first connecting portion 410 is provided with a first external connecting structure 411, and the outer surface of the second connecting portion 420 is provided with a second external connecting structure 421. Figure 13 and Figure 14 As shown, the first connecting portion 410, the second connecting portion 420, and the main body portion 430A of the outer lamp cover 400A together define the first opening 401, the second opening 402, and the storage space 403. The storage space 403 is used to store at least a portion of the light-emitting component 300A. One end of the light-emitting component 300A can extend into the storage space 403 from the first opening 401 or the second opening 402.

[0051] For example, the first connecting portion 410 is disposed outside the first end portion 4301 of the main body portion 430A, and the second connecting portion 420 is disposed outside the second end portion 4302 of the main body portion 430A, with the first end portion 4301 and the second end portion 4302 of the main body portion 430A disposed opposite to each other.

[0052] The first connecting part 410, the main body part 430A, and the second connecting part 420 can be integrally formed, for example, by injection molding. The connection method and processing technology of the first connecting part 410, the main body part 430A, and the second connecting part 420 are not limited thereto, and this application does not impose any restrictions on the connection method and processing technology of the first connecting part 410, the main body part 430A, and the second connecting part 420.

[0053] The shape of the main body 430A can be regular or irregular. For example, the shape of the main body 430A can be a cylindrical structure, and the outer diameter and inner diameter of each position of the main body 430A can be the same; or it can be understood as the wall thickness of each position of the main body 430A being the same.

[0054] For example, at least two lamp holders (100A, 200A) are connected to a light-emitting component 300A and an outer lamp cover 400A. The at least two lamp holders (100A, 200A) connecting the light-emitting component 300A and the outer lamp cover 400A include a first lamp holder 100A and a second lamp holder 200A. Each lamp holder (100A, 200A) includes a first base (120, 220) and a second base (120, 220), with the first base (110, 210) and the second base (120, 220) spaced apart and the first base (120, 220) located outside the second base (120, 220); the inner side of the first base (110, 210) of each lamp holder (100A, 200A) is provided with an inner connecting structure (111, 211), and the inner connecting structure (111, 211) and the outer connecting structure (411, 421) can be rotated relative to each other to connect or separate. The inner connecting structure (111, 211) and the outer connecting structure (411, 421) can be connected or separated by relative rotation. For example, this can be understood as: the inner connecting structure (111, 211) and the outer connecting structure (411, 421) can be connected and fixed together by relative rotation, or the inner connecting structure (111, 211) and the outer connecting structure (411, 421) can be separated by relative rotation. The inner connecting structure (111, 211) and the outer connecting structure (411, 421) can be rotated relative to each other. For example, this can be understood as: the inner connecting structure (111, 211) can rotate relative to the outer connecting structure (411, 421), or the outer connecting structure (411, 421) can rotate relative to the inner connecting structure (111, 211).

[0055] For example, the first lamp holder 100A includes a first base 110 and a second base 120, which are spaced apart, with the first base 110 located outside the second base 120. The spaced-apart relationship between the first base 110 and the second base 120 can be understood as follows: the first base 110 and the second base 120 are not directly connected. For instance, the first lamp holder 100A also includes a third base 130, which is connected to one end of the first base 110 and one end of the second base 120; that is, the third base 130 is connected to the same end of both the first base 110 and the second base 120. The first base 110, the second base 120, and the third base 130 together define a space 140 with an opening. The opening of the space 140 allows the first connecting portion 410 of the outer lampshade 400A and its first external connecting structure 411 to extend into it. The space 140 can accommodate at least a portion of the first connecting portion 410 of the outer lampshade 400A and its first external connecting structure 411. The first base 110 being located outside the second base 120 can be understood as: the first base 110 being disposed around at least a portion of the second base 120; or it can be understood as: at least a portion of the second base 120 being disposed within the space surrounded by the first base 110. For example, the inner surface 1102 of the first base 110 of the first lamp holder 100A is provided with a first inner connecting structure 111. The first inner connecting structure 111 and the first external connecting structure 411 can rotate relative to each other to connect or separate. The first base 110, the second base 120, and the third base 130 can be integrally formed, for example, by injection molding. The connection method and processing technology of the first base 110, the second base 120, and the third base 130 are not limited thereto; this application does not impose any restrictions on the connection method and processing technology of the first base 110, the second base 120, and the third base 130. The outer surface 131 of the third base 130 can be a regular shape or an irregular shape. The outer surface 131 of the third base 130 can be a plane or a curved surface. For example, as shown... Figure 11 As shown, the outer surface 131 of the third seat 130 in this embodiment is illustrated by way of a plane.

[0056] For example, the second lamp holder 200A includes a first base 210 and a second base 220, which are spaced apart, with the first base 210 located outside the second base 220. The spaced-apart relationship between the first base 210 and the second base 220 can be understood as a non-direct connection. For instance, the second lamp holder 200A also includes a third base 230, which is connected to one end of the first base 210 and one end of the second base 220; that is, the third base 230 is connected to the same end of both the first base 210 and the second base 220. The first base 210, the second base 220, and the third base 230 together define a space 240 with an opening. The opening of the space 240 allows the second connecting portion 420 of the outer lamp cover 400A and its second external connecting structure 421 to extend into it. The space 240 can accommodate at least a portion of the second connecting portion 420 of the outer lamp cover 400A and its second external connecting structure 421. The first base 210 being located outside the second base 220 can be understood as: the first base 210 being disposed around at least a portion of the second base 220; or as: at least a portion of the second base 220 being disposed within the space surrounded by the first base 210. For example, the inner surface of the first base 210 of the second lamp holder 200A is provided with a second inner connecting structure 211, and the second inner connecting structure 211 and the second external connecting structure 421 can be rotated relative to each other to connect or separate. The first base 210, the second base 220, and the third base 230 can be integrally formed, for example, by injection molding. The connection method and processing technology of the first base 210, the second base 220, and the third base 230 are not limited thereto; this application does not impose any restrictions on the connection method and processing technology of the first base 210, the second base 220, and the third base 230. The outer surface 231 of the third base 230 can be a regular shape or an irregular shape. The outer surface 231 of the third base 230 can be a plane or a curved surface. For example, as shown... Figure 11 As shown, the outer surface 231 of the third seat 230 in this embodiment is illustrated by way of a plane.

[0057] It is understood that the first seat 110 includes opposite outer side 1101 and inner side 1102, and the first seat 210 includes opposite outer side and inner side. The outer side of the first seat 210 of this application can be referred to as the outer side 1101 of the first seat 110, and the inner side of the first seat 210 of this application can be referred to as the inner side 1102 of the first seat 110, which will not be described in detail here.

[0058] In one optional embodiment of this application, the first lamp holder 100A and the second lamp holder 200A have the same shape, for example... Figures 1 to 11The first lamp holder 100A and the second lamp holder 200A shown are identical in shape, wherein... Figure 12 The diagram shows the three-dimensional structure of the first lamp holder 100A. The three-dimensional structure of the second lamp holder 200A can be referenced. Figure 12 The first lamp holder 100A is shown in the diagram. This application will not further illustrate the three-dimensional structure of the second lamp holder 200A, which has the same shape as the first lamp holder 100A. In another optional embodiment of this application, the first lamp holder 100A and the second lamp holder 200A have different shapes, which will be further illustrated below with reference to other accompanying drawings.

[0059] For example, the first base 110 of the first lamp holder 100A is connected to the first connecting portion 410, and the second base 120 of the first lamp holder 100A is provided with a third electrical connection terminal 180. The third electrical connection terminal 180 and the first electrical connection terminal 310 can be inserted and connected together by rotating relative to each other around the same axis P1 to achieve physical and electrical connection. The connection relationship between the first base 110 and the first connecting portion 410 is, for example, that the first inner connecting structure 111 and the first outer connecting structure 411 are connected. At least a portion of the third electrical connection terminal 180 can be disposed in the second base 120, so that the third electrical connection terminal 180 can be fixed on the second base 120. In one optional embodiment of this application, the third electrical connection terminal 180 is fixed on the second base 120 in a non-removable manner. In another optional embodiment of this application, the third electrical connection terminal 180 is fixed on the second base 120 in a detachable manner, that is, the third electrical connection terminal 180 can be installed on the second base 120 and can be removed from the second base 120 for easy replacement. For example, the second base 120 has an installation space 121, and at least a portion of the third electrical connection terminal 180 can be installed into the installation space 121 and fit against the wall forming the installation space 121. The opening of the installation space 121 is located on the side of the second base 120 away from the third base 130. The first base 100A also includes a through hole 150 for a wire such as wire 172 to pass through. The through hole 150 passes through the third base 130 and the second base 120 and communicates with the internal space of the second base 120. Specifically, the through hole 150 communicates with the installation space 121. The through hole 150 can accommodate the wire such as wire 172. At least a portion of the third electrical connection terminal 180 installed in the installation space 121 can be electrically connected to the wire 172. The wire 172 can be connected to a power source to power the light-emitting component 300A. The ability of the third electrical connection terminal 180 and the first electrical connection terminal 310 to be rotatably connected around the same axis P1 can be understood as follows: both the third electrical connection terminal 180 and the first electrical connection terminal 310 can rotate relative to each other around the same axis P1, and both can be plugged into each other. For example, the first electrical connection terminal 310 can rotate relative to the third electrical connection terminal 180 around axis P1, and the third electrical connection terminal 180 can rotate relative to the first electrical connection terminal 310 around axis P1. For example, the first electrical connection terminal 310 can be inserted into the third electrical connection terminal 180 to achieve a physical and electrical connection. The power source can be a built-in power source included in the lamp 10A, or an external power source not included in the lamp 10A. The built-in power source can be a rechargeable power source or a non-rechargeable power source. When the built-in power source is a rechargeable power source, it can be charged using mains power or a mobile energy storage device, or it can be charged using solar energy.External power sources include the mains power grid, mobile energy storage devices, power banks, or independent solar power generation devices.

[0060] For example, the first base 210 and the second connecting portion 420 of the second lamp holder 200A are connected. The second base 220 of the second lamp holder 200A is provided with a fourth electrical connection terminal 280. The fourth electrical connection terminal 280 and the second electrical connection terminal 320 can be inserted and connected together by relative rotation around the same axis P1 to achieve physical and electrical connection. The connection relationship between the first base 210 and the second connecting portion 420 is, for example, that the second inner connecting structure 211 and the second outer connecting structure 421 are connected. At least a portion of the fourth electrical connection terminal 280 can be disposed in the second base 220, so that the fourth electrical connection terminal 280 can be fixed on the second base 220. In one optional embodiment of this application, the fourth electrical connection terminal 280 is fixed on the second base 220 in a non-removable manner. In another optional embodiment of this application, the fourth electrical connection terminal 280 is fixed on the second base 220 in a detachable manner, that is, the fourth electrical connection terminal 280 can be installed on the second base 220 and can be removed from the second base 220 for easy replacement. For example, the second base 220 has an installation space 221, into which at least a portion of the fourth electrical connection terminal 280 can be installed and fit against the wall forming the installation space 221. The opening of the installation space 221 is located on the side of the second base 220 away from the third base 230. The second base 200A also includes a through hole 250 through which a wire, such as a wire 272, passes. The through hole 250 penetrates the third base 230 and the second base 220 and communicates with the internal space of the second base 220. Specifically, the through hole 250 communicates with the installation space 221 and can accommodate the wire, such as the wire 272. At least a portion of the fourth electrical connection terminal 280 installed in the installation space 221 can be electrically connected to the wire 272. The wire 272 can be connected to other light-emitting components to supply power to those components, or it can be connected to a packaging component. The ability of the fourth electrical connection terminal 280 and the second electrical connection terminal 320 to be rotatably connected about the same axis P1 can be understood as follows: both the fourth electrical connection terminal 280 and the second electrical connection terminal 320 can rotate about the same axis P1, and both can be plugged into each other. For example, the second electrical connection terminal 320 can rotate about axis P1 relative to the fourth electrical connection terminal 280, and the fourth electrical connection terminal 280 can rotate about axis P1 relative to the second electrical connection terminal 320. For example, the second electrical connection terminal 320 can be inserted into the fourth electrical connection terminal 280 to achieve a physical and electrical connection.

[0061] During the relative rotation of the inner connection structure of the first lamp holder 100A, such as the first inner connection structure 111, and the outer connection structure of the first connection part 410, such as the first outer connection structure 411, the third electrical connection terminal 180 and the first electrical connection terminal 310 simultaneously rotate relative to each other or remain relatively stationary; and / or, during the relative rotation of the inner connection structure of the second lamp holder 200A, such as the second inner connection structure 211, and the outer connection structure of the second connection part 420, such as the second outer connection structure 421, the fourth electrical connection terminal 280 and the second electrical connection terminal 320 simultaneously rotate relative to each other or remain relatively stationary.

[0062] For example, the first base 110, the second base 120, and the third electrical connection terminal 180 of the first lamp holder 100A are coaxially arranged; for example, the first base 110, the second base 120, and the third electrical connection terminal 180 have the same axis P1, and the first base 110, the second base 120, and the third electrical connection terminal 180 can rotate around the axis P1 simultaneously.

[0063] For example, the first base 210, the second base 220, and the fourth electrical connection terminal 280 of the second lamp holder 200A are coaxially arranged; for example, the first base 210, the second base 220, and the fourth electrical connection terminal 280 have the same axis P1, and the first base 210, the second base 220, and the fourth electrical connection terminal 280 can rotate around the axis P1 simultaneously.

[0064] For example, during the relative rotation of the second inner connection structure 221 of the second base 220 and the second outer connection structure 421 of the second connection portion 420, the third electrical connection terminal 180 and the first electrical connection terminal 310 rotate relative to each other, while the fourth electrical connection terminal 280 and the second electrical connection terminal 320 remain relatively stationary; or, the third electrical connection terminal 180 and the first electrical connection terminal 310 remain relatively stationary while the fourth electrical connection terminal 280 and the second electrical connection terminal 320 rotate relative to each other.

[0065] Let's take an example to illustrate the first assembly process of a single light-emitting device in a lamp: Assembly Step 11: Assemble a lamp holder, such as the first lamp holder 100A, and a light-emitting component 300A. Specifically, assemble the third electrical connection terminal 180 on the second base 120 of the first lamp holder 100A and the first electrical connection terminal 310 of the light-emitting component 300A. For example, the third electrical connection terminal 180 and the first electrical connection terminal 310 can be directly plugged in until the plugging is completed to complete the assembly, or the third electrical connection terminal 180 and the first electrical connection terminal 310 can be rotatably plugged in until the plugging is completed to complete the assembly.

[0066] Assembly Step 12: Assemble a lamp holder, such as a first lamp holder 100A, and an outer lamp cover 400A. First, align an opening of the outer lamp cover 400A, such as a first opening 401, with the second electrical connection terminal 320 of the light-emitting component 300A; then, the first connecting portion 410 of the outer lamp cover 400A passes through the light-emitting component 300A and is assembled with the first base 110 of the first lamp holder 100A. Specifically, the first external connecting structure 411 on the first connecting portion 410 of the outer lamp cover 400A and the first internal connecting structure 111 on the first base 110 are connected to each other, such as by a threaded connection, to assemble the outer lamp cover 400A and the first lamp holder 100A. It should be noted that during the assembly process of this assembly step 12, the outer lamp cover 400A and the light-emitting component 300A remain spaced apart and do not contact each other. It should also be noted that completing assembly steps 11 and 12 will achieve a physical connection between a lamp holder, such as the first lamp holder 100A, and the outer lamp cover 400A, as well as a physical and electrical connection between the first lamp holder 100A and the light-emitting component 300A.

[0067] Assembly Step 13: Another lamp holder, such as the second lamp holder 200A, is assembled simultaneously with the light-emitting component 300A and the outer lamp cover 400A. First, the fourth electrical connection terminal 280 on the second base 220 of the second lamp holder 200A aligns with the second electrical connection terminal 320 of the light-emitting component 300A, and the first base 110 of the second lamp holder 200A aligns with the second connecting portion 420 of the outer lamp cover 400A. Then, the second lamp holder 200A and the outer lamp cover 400A are driven to rotate relative to each other until the connection between the second inner connecting structure 211 of the second lamp holder 200A and the second outer connecting structure 421 of the second connecting portion 420 is completed, thereby realizing the simultaneous assembly of the second lamp holder 200A with the light-emitting component 300A and the outer lamp cover 400A. Specifically, after the fourth electrical connection terminal 280 and the second electrical connection terminal 320 are aligned, and the first base 110 and the second connecting part 420 are aligned, the second lamp holder 200A and the outer lamp cover 400A are driven to rotate relative to each other. During the relative rotation of the second lamp holder 200A and the outer lamp cover 400A, the connection area between the second inner connecting structure 211 and the second outer connecting structure 421 gradually increases. At the same time, the fourth electrical connection terminal 280 and the second electrical connection terminal 320 are either inserted relative to each other with rotation or directly inserted relative to each other without rotation, thereby gradually increasing the insertion area between the fourth electrical connection terminal 280 and the second electrical connection terminal 321. When the connection action between the second inner connecting structure 211 and the second outer connecting structure 421 ends, or when the connection action terminates, the first base 210 and the second connecting part 420 are connected, and the fourth electrical connection terminal 280 and the second electrical connection terminal 320 are inserted. It should be noted that during the relative rotation of the second lamp holder 200A and the outer lamp cover 400A, the first base 210, the second base 220, and the fourth electrical connection terminal 280 on the second base 220 of the second lamp holder 200A all rotate relative to the outer lamp cover 400A, such as rotating around axis P1. The relative states between the components in step 3 are illustrated below.

[0068] In the first case: during the connection between the first base 210 and the second connecting part 420, the first base 210, the second base 220 and the fourth electrical connection terminal 280 all rotate around the axis P1 relative to the outer lamp cover 400A and the light-emitting component 300A. In this case, the first base 210 and the second connecting part 420 are connected to each other by a threaded connection, and the fourth electrical connection terminal 280 and the second electrical connection terminal 320 are inserted relative to each other in a rotatable manner. The first electrical connection terminal 310 and the third electrical connection terminal 180 do not rotate relative to each other, for example, the first electrical connection terminal 310 and the third electrical connection terminal 180 are in a stationary state.

[0069] In the second scenario: during the connection process between the first base 210 and the second connecting part 420, the first base 210, the second base 220, and the fourth electrical connection terminal 280 all rotate around axis P1 relative to the outer lamp cover 400A. In this scenario, the first base 210 and the second connecting part 420 are connected to each other by a threaded connection, the light-emitting component 300A rotates together with the fourth electrical connection terminal 280, and the fourth electrical connection terminal 280 and the second electrical connection terminal 320 are plugged into each other, and the first electrical connection terminal 310 rotates around axis P1 relative to the third electrical connection terminal 180.

[0070] The third scenario: During the connection process between the first base 210 and the second connecting part 420, the first base 210, the second base 220, and the fourth electrical connection terminal 280 all rotate relative to the outer lamp cover 400A around axis P1. During this connection process, the light-emitting component 300A exists in both a non-rotating state and a rotating state. For example, during the connection process between the first base 210 and the second connecting part 420, the light-emitting component 300A is initially in a rotating state and then switches to a non-rotating state. For example, in the first stage of the connection process between the first base 210 and the second connecting part 420: the light-emitting component 300A first rotates together with the fourth electrical connection terminal 280. At this time, the fourth electrical connection terminal 280 and the second electrical connection terminal 320 are rotatably inserted into each other, while the first electrical connection terminal 310 and the third electrical connection terminal 180 do not rotate relative to each other, for example, the first electrical connection terminal 310 and the third electrical connection terminal 180 are in a stationary state. The second stage of the connection process between the first base 210 and the second connecting part 420 is as follows: the light-emitting component 300A switches to a non-rotating state relative to the fourth electrical connection terminal 280. At this time, the fourth electrical connection terminal 280 and the second electrical connection terminal 320 are plugged into each other, and the first electrical connection terminal 310 and the third electrical connection terminal 180 rotate relative to each other.

[0071] To illustrate the second assembly process of the light-emitting device in a lamp, the first lamp holder 100A and the second lamp holder 200A are interchanged. For the specific assembly steps, please refer to the first assembly process, which will not be repeated here.

[0072] To illustrate the third assembly process of a single light-emitting device in a lamp: Assembly step 31: A lamp holder, such as the first lamp holder 100A, and a light-emitting component 300A are partially assembled. Specifically, the third electrical connection terminal 180 on the second base 120 of the first lamp holder 100A and the first electrical connection terminal 310 of the light-emitting component 300A are partially assembled. For example, the third electrical connection terminal 180 and the first electrical connection terminal 310 are directly inserted into each other to complete the connection and achieve partial assembly, or the third electrical connection terminal 180 and the first electrical connection terminal 310 are inserted into each other by relative rotation rather than complete the connection and achieve partial assembly.

[0073] Assembly Step 32: Partial Assembly of the First Lamp Holder 100A and the Outer Lamp Cover 400A. First, an opening of the outer lamp cover 400A, such as the first opening 401, is aligned with the second electrical connection terminal 320 of the light-emitting component 300A; then, the first connecting portion 410 of the outer lamp cover 400A passes through the light-emitting component 300A and is partially assembled with the first base 110 of the first lamp holder 100A. Specifically, the first external connecting structure 411 on the first connecting portion 410 of the outer lamp cover 400A and the first internal connecting structure 111 on the first base 110 are connected to each other, such as a partial threaded connection rather than a complete connection, to achieve the partial assembly of the outer lamp cover 400A and the first lamp holder 100A.

[0074] Assembly step 33: The second lamp holder 200A is partially assembled with the outer lamp cover 400A and the light-emitting component 300A. Specifically, the first base and the second connecting part 420 are partially connected rather than fully connected to achieve partial assembly, and the fourth electrical connection terminal 280 and the second electrical connection terminal 320 on the second base 220 are partially directly plugged into each other rather than fully plugged in, or partially plugged in with relative rotation rather than fully plugged in, to achieve partial assembly.

[0075] Assembly Step 34: Simultaneously drive the first lamp holder 100A and the second lamp holder 200A to rotate relative to the outer lamp cover 400A. For example, the first lamp holder 100A rotates clockwise relative to the outer lamp cover 400A about axis P1, and the second lamp holder 200A rotates counterclockwise relative to the outer lamp cover 400A about axis P1, until the first connecting part 410 and the first base 110 are completely connected, and the second connecting part 420 and the first base 210 are completely connected. During this assembly step 34, at least one of the first lamp holder 100A and the second lamp holder 200A may or may not rotate relative to the light-emitting component 300A. First case: The light-emitting component 300A rotates together with the first lamp holder 100A. In this case, the light-emitting component 300A does not rotate relative to the first lamp holder 100A, but rotates relative to the second lamp holder 200A. The second scenario: The light-emitting component 300A rotates together with the second lamp holder 200A. In this case, the light-emitting component 300A does not rotate relative to the second lamp holder 200A, but rotates relative to the first lamp holder 100A. The third scenario: The light-emitting component 300A rotates relative to both the first lamp holder 100A and the second lamp holder 200A.

This increases the connection stability between the first lamp holder 100A and the second lamp holder 200A and the outer lamp cover 400A, and also improves the sealing performance of the connections (X1, X2) between the first lamp holder 100A and the second lamp holder 200A and the outer lamp cover 400A.

[0081] For example, the outer surface 1101 of the first seat 110 is flush with the outer surface of the main body 430A, and the first connection point X1 between the first seat 110 and the main body 430A is smoothly transitioned. The outer surface of the first seat 210 is flush with the outer surface of the main body 430A, and the second connection point X2 between the first seat 210 and the main body 430A is smoothly transitioned.

[0082] like Figure 8 , Figure 10 , Figure 11 and Figure 12As shown, the first lamp holder 100A also includes a limiting structure 160, which is disposed on the inner side of the third base 130. Exemplarily, the limiting structure 160 is disposed in the interval space 140, within the first base 110, and surrounds the second base 120, thereby defining the interval space 140 as a first sub-interval space 141 and a second sub-interval space 142. Specifically, the limiting structure 160 and the first base 110 define the first sub-interval space 141, and the limiting structure 160 and the second base 120 define the second sub-interval space 142. The first connecting portion 410 and the first external connecting structure 411 on the outer side of the first connecting portion 410 are both confined within the first sub-interval space 141. The second lamp holder 200A also includes a limiting structure 260, which is disposed on the inner side of the third base 230. For example, the limiting structure 260 is disposed in the interval space 240, within the first seat 210, and surrounding the second seat 220. Thus, the limiting structure 260 defines the interval space 240 as a first sub-interval space and a second sub-interval space. Specifically, the limiting structure 260 and the first seat 210 define the first sub-interval space, and the limiting structure 260 and the second seat 220 define the second sub-interval space. The second connecting portion 420 and the second external connecting structure 421 on the outer side of the second connecting portion 420 are both confined within the first sub-interval space of the interval space 240. This improves the connection stability between the first lamp holder 100A and the second lamp holder 200A and the outer lamp cover 400A.

[0083] For example, the length of the limiting structure 160 along the axis P1 is less than the length of the first seat 110 along the axis P1 and less than the length of the second seat 120 along the axis P1. The length of the limiting structure 260 along the axis P1 is less than the length of the first seat 210 along the axis P1 and less than the length of the second seat 220 along the axis P1.

[0084] For example, the shapes of the limiting structure 160 and the limiting structure 260 can be regular or irregular. For example, the size of the limiting structure 160 gradually increases from the end away from the third seat 130 to the end where the limiting structure 160 and the third seat 130 are connected. For example, the size of the limiting structure 260 gradually increases from the end away from the third seat 230 to the end where the limiting structure 260 and the third seat 230 are connected.

[0085] For example, the first lamp holder 100A may further include an extension 170, which is connected to the third base 130, for example, the extension 170 is connected to the outer surface 131 of the third base 130. The through hole 150 of the first lamp holder 100A may also pass through the extension 170. The second lamp holder 200A may further include an extension 270, which is connected to the third base 230, for example, the extension 270 is connected to the outer surface 231 of the third base 230. The through hole 250 of the second lamp holder 200A may also pass through the extension 270.

[0086] In one optional embodiment of this application, a portion of the second base 120 of the first lamp holder 100A is disposed within the space defined by the first base 110, and another portion is disposed outside the first base 110. For example, the second base 120 may include a first portion 1201 and a second portion 1202, with the first portion 1201 disposed within the space defined by the first base 110 and the second portion 1202 disposed outside the first base 110. In this embodiment, the third electrical connection terminal 180 may be partially disposed within the space defined by the first base 110 and partially disposed outside the first base 110, for example, a portion of the third electrical connection terminal 180 may be disposed within the first portion 1201 and another portion may be disposed within the second portion 1202; or the third electrical connection terminal 180 may be entirely disposed outside the space defined by the first base 110, for example, the third electrical connection terminal 180 may be disposed within the second portion 1202.

[0087] In one optional embodiment of this application, a portion of the second base 220 of the second lamp holder 200A is disposed within the space defined by the first base 210, and another portion is disposed outside the first base 210. For example, the second base 220 may include a first portion 2201 and a second portion 2202, with the first portion 2201 disposed within the space defined by the first base 210 and the second portion 2202 disposed outside the first base 210. In this embodiment, the fourth electrical connection terminal 280 may be partially disposed within the space defined by the first base 210 and partially disposed outside the first base 210, for example, a portion of the fourth electrical connection terminal 280 may be disposed within the first portion 2201 and the other portion may be disposed within the second portion 2202; or the fourth electrical connection terminal 280 may be entirely disposed outside the space defined by the first base 210, for example, the fourth electrical connection terminal 280 may be disposed within the second portion 2202.

[0088] In one optional embodiment of this application, the second base 120 and the third electrical connection terminal 180 of the first lamp holder 100A are disposed within the space defined by the first base 110. For example, both the second base 120 and the third electrical connection terminal 180 are disposed within the space defined by the first base 110 and do not extend outside the first base 110. The embodiment will be described exemplarily below with reference to other accompanying drawings.

[0089] In one optional embodiment of this application, the second base 220 and the fourth electrical connection terminal 280 of the second lamp holder 200A are disposed within the space defined by the first base 210. For example, both the second base 220 and the fourth electrical connection terminal 280 are disposed within the space defined by the first base 210 and do not extend outside the first base 210. The embodiment will be described exemplarily below with reference to other accompanying drawings.

[0090] In one optional embodiment of this application, the first base 110, the second base 120, and the third electrical connection terminal 180 of the first lamp holder 100A are coaxially arranged; the first base 210, the second base 220, and the fourth electrical connection terminal 280 of the second lamp holder 200A are coaxially arranged; the first electrical connection terminal 310 and the second electrical connection terminal 320 are coaxially arranged. The first base 110, the second base 120, and the third electrical connection terminal 180 of the first lamp holder 100A are rotatable relative to the first electrical connection terminal 310 relative to axis P1; the first base 210, the second base 220, and the fourth electrical connection terminal 280 of the second lamp holder 200A are rotatable relative to the second electrical connection terminal 320 relative to axis P1.

[0091] like Figures 16 to 21 As shown, combined Figures 1 to 15 The difference between lamp 10B and lamp 10A includes that lamp 10B further includes at least one inner lampshade 500A. Components and structures identical to those in lamp 10B and lamp 10A are marked with the same symbols, and specific details can be found in the above description of lamp 10A, which will not be repeated here. The inner lampshade 500A is disposed within the space defined by the connection of the first lamp holder 100A, the outer lampshade 400A, and the second lamp holder 200A. In this embodiment, the space defined by the connection of the first lamp holder 100A, the outer lampshade 400A, and the second lamp holder 200A can be referred to as the accommodating space Y. One or more light-emitting components 332 of the light-emitting body 310A are disposed within the inner lampshade 500A, meaning that the inner lampshade 500A at least covers all light-emitting components 332 of the light-emitting body 310A. The light emitted by the light-emitting component 332 first passes through the inner lamp cover 500A, and the inner lamp cover 500A can diffuse the light emitted by the light-emitting component 332.

[0092] For example, the inner lampshade 500A is connected in the following ways: the inner lampshade 500A is fitted onto the outer side of the second base 120 of the first lamp holder 100A, and the inner lampshade 500A is fitted onto the outer side of the second base 220 of the second lamp holder 200A. Thus, the inner lampshade 500A covers a portion of the second base 120, a portion of the second base 220, and the portion of the light-emitting component 300A located between the first base 210 and the second base 220, effectively diffusing the light emitted by the light-emitting component 332 of the light-emitting component 300A.

[0093] In one optional embodiment of this application, the inner lampshade 500A and the second base 120 can be rotatably connected or separated, and the inner lampshade 500A and the second base 220 can be rotatably connected or separated. For example, the inner lampshade 500A and the second base 120 are slidably connected, and the inner lampshade 500A and the second base 220 are slidably connected.

[0094] In one optional embodiment of this application, an intermediate layer, such as an adhesive layer, connects the inner lampshade 500A and the second base 120, and also connects the inner lampshade 500A and the second base 220, thereby achieving a seamless and / or sealed connection between the inner lampshade 500A and the second base 120A, and a seamless and / or sealed connection between the inner lampshade 500A and the second base 220A. This ensures that all light-emitting components 332 of the light-emitting assembly 300A are completely confined within the space defined by the second base 120, the inner lampshade 500A, and the second base 220. The light emitted by the light-emitting components 332 of the light-emitting body 330A is transmitted to the outside through the inner lampshade 500A and the outer lampshade 400A in sequence. This improves the connection stability between the inner lampshade 500A and the first base 210 and the second base 220, and further enhances the waterproof performance of the lamp, making it suitable for various scenarios such as outdoor and underwater environments.

[0095] like Figure 22 and Figure 23 As shown, combined Figures 1 to 21The inner lampshade 500A and the second base 120B of the first lamp holder 100B can be connected or separated by relative rotation, and the inner lampshade 500A and the second base 220B of the second lamp holder 200B can be connected or separated by relative rotation, including: threaded connection between the inner lampshade 500A and the second base 120B, and threaded connection between the inner lampshade 500A and the first base 210B and the second base 220B. On the one hand, it can improve the connection stability between the inner lampshade 500A and the first base 210B and the second base 220B. On the other hand, the threaded connection between the inner lampshade 500A and the first base 210B and the second base 220B achieves seamless connection and / or sealed connection between the inner lampshade 500A and the first base 210B and the second base 220B, which can further improve the waterproof performance of the lamp, so that the lamp can be used in various scenarios such as outdoor and underwater. For example, the inner lampshade 500A and the second base 120B of the first lamp holder 100B are seamlessly and sealed together, as are the second base 220B of the inner lampshade 500A and the second lamp holder 200B, so that all the light-emitting components 332 of the light-emitting body 330A are completely confined within the space defined by the second base 120B of the first lamp holder 100B, the inner lampshade 500A, and the second base 220B of the second lamp holder 200B; the light emitted by the light-emitting components 332 of the light-emitting body 330A is transmitted to the outside through the inner lampshade 500A and the outer lampshade 400A in sequence. Specifically, the outer surface of the second base 120B is provided with a first threaded structure 122B, and the outer surface of the second base 220B is provided with a second threaded structure 222B. Correspondingly, the inner surface of the inner lampshade 500A can be provided with a corresponding threaded structure, so that the inner lampshade 500A can be threadedly connected with the first threaded structure 122B and the second threaded structure 222B.

[0096] For example, the first threaded structure 122B is disposed on the second part of the second seat 120B, but not on the first part of the second seat 120B; the second threaded structure 222B is disposed on the second part of the second seat 220B, but not on the first part of the second seat 220B. It should be noted that the first and second parts of the second seat 120B can refer to the first part 1201 and the second part 1202 of the second seat 120, and the first and second parts of the second seat 220B can refer to the first part 2201 and the second part 2202 of the second seat 220, which will not be elaborated further here. In this embodiment, the inner lampshade 500A is connected to the second part of the second seat 120B and terminates at the first part of the second seat 120B, and the inner lampshade 500A is connected to the second part of the second seat 220B and terminates at the first part of the second seat 220B. This prevents the inner lampshade 500A from interfering with the connection between the outer lampshade 400A and the first base 110 and the second base 120.

[0097] In other optional embodiments, the second base 120 of the inner lamp cover 500A and the first lamp holder 100A can be rotated relative to each other to connect or separate, and the second base 220 of the inner lamp cover 500A and the second lamp holder 200A can be rotated relative to each other to connect or separate, including: the second base of the inner lamp cover 500A and the second base of the first lamp holder are threadedly connected, or the second base of the inner lamp cover and the second lamp holder are slidably connected; or, the second base of the inner lamp cover and the second base of the first lamp holder are slidably connected, or the second base of the inner lamp cover and the second lamp holder are threadedly connected.

[0098] It should be noted that the connection method of the inner lamp cover 500A is not limited to connecting to the first lamp holder and the second lamp holder. Other optional embodiments include connecting the inner lamp cover 500A and the light-emitting component 300A. The following description is based on other accompanying drawings.

[0099] like Figure 24 , Figure 25 and Figure 26As shown, the differences between luminaire 10C and luminaire 10B include: the connection between the inner lampshade 500B and the light-emitting component 300B in luminaire 10C. Similarly, components and structures identical to those in luminaire 10A and luminaire 10B in luminaire 10C are marked with the same symbols; please refer to the above description for details, which will not be repeated here. For example, the light-emitting component 300B includes a first electrical connection terminal 310, a second electrical connection terminal 320, a rigid circuit board 330B, and one or more light-emitting components 332 disposed on the rigid circuit board 330B. The connection relationship between the first electrical connection terminal 310, the second electrical connection terminal 320, and the rigid circuit board 330B can be referred to the above description, which will not be repeated here. The difference between light-emitting component 300B and light-emitting component 300A includes that the rigid circuit board 331B of light-emitting component 300B is provided with a limiting structure to limit the inner lampshade 500B. For example, the rigid circuit board 331B includes at least one first limiting structure 3311 and at least one second limiting structure 3312. In one optional embodiment, a first limiting structure 3311 and a second limiting structure 3312 are disposed on the same side of the rigid circuit board 331B, such as the first side 3303, and on the other side of the rigid circuit board 331B, such as the second side 3304. The first limiting structure 3311 and the second limiting structure 3312 located on the first side 3303 define a limiting groove 3313, and the first limiting structure 3311 and the second limiting structure 3312 located on the second side 3303 also define a limiting groove 3313. The two first limiting structures 3311 are disposed opposite to each other, the two second limiting structures 3312 are disposed opposite to each other, and the two limiting grooves 3313 are disposed opposite to each other. A portion of the inner lampshade 500B is disposed within the two limiting grooves 3313 and is limited by the two first limiting structures 3311 and the two second limiting structures 3312. For example, two first limiting structures 3311 are located near the first end 3301 of the rigid circuit board 331B, and two second limiting structures 3312 are located near the second end 3302 of the rigid circuit board 331B. The two first limiting structures 3311 and the two second limiting structures 3312 are located at the corner positions of the rigid circuit board 331B, that is, one first limiting structure 3311 is located at the junction of the first end 3301 and the first side portion 3303, and the other first limiting structure 3311 is located at the junction of the first end 3301 and the second side portion 3304; one second limiting structure 3312 is located at the junction of the second end 3302 and the first side portion 3303, and the other second limiting structure 3312 is located at the junction of the second end 3302 and the second side portion 3304.In other alternative embodiments, the rigid circuit board 331B includes only one first limiting structure 3311 and one second limiting structure 3312, which are disposed on the first side 3303 or the second side 3304 of the rigid circuit board 331B. In this embodiment, a portion of the light emitted by the light-emitting component 332 of the light-emitting body 330B is transmitted to the outer lamp cover 400A through the inner lamp cover 500B, and another portion is transmitted to the outer lamp cover 400A from the openings at both ends of the inner lamp cover 500B. The inner lamp cover 500B can diffuse a portion of the light emitted by the light-emitting component 332, and the embodiments of this application can improve the light emission effect to a certain extent.

[0100] It should be noted that the lengths of rigid circuit boards 331A and 331B can be set according to requirements. The lengths of rigid circuit boards 331A and 331B can be referenced... Figure 26 The length of the first direction F1 is shown.

[0101] like Figure 27 , Figure 28 and Figure 29 As shown, the differences between luminaire 10D and luminaire 10A include: the first lamp holder 100D in luminaire 10D has a different structure than the first lamp holder 100A in luminaire 10A, and the second lamp holder 200D in luminaire 10D has a different structure than the second lamp holder 200A in luminaire 10A. For example, the structure of the outer surface 131D of the third base 130D in the first lamp holder 100D differs from the structure of the outer surface 131 of the third base 130. For instance, the outer surface 131 of the third base 130 is planar, while the outer surface 131D of the third base 130D is curved. Similarly, the structure of the outer surface 231D of the third base 230D in the second lamp holder 200D differs from the structure of the outer surface 231 of the third base 230. For instance, the outer surface 231 of the third base 230 is planar, while the outer surface 231D of the third base 230D is curved. In one optional embodiment of this application, both the third base 130D and the third base 230D have a frustum-shaped structure. The cross-section of both the third base 130D and the third base 230D is circular. The diameter of the third base 130D gradually increases from the end connected to the extension 170 to the end connected to the first base 110 and the second base 120. The diameter of the third base 230D gradually increases from the end connected to the extension 270 to the end connected to the first base 210 and the second base 220. Components and structures identical to those in the lamp 10D and lamp 10A are marked with the same symbols, and specific details can be found in the above description of lamp 10A, which will not be repeated here.

[0102] In other alternative embodiments, one of the lamp holders in luminaire 10D can be replaced with one of the lamp holders in luminaire 10A.

[0103] like Figure 30 , Figure 31 , Figure 32 , Figure 33 , Figure 34 and Figure 35 As shown, the differences between luminaire 10E and luminaires 10A and luminaire 10D include: the first lamp holder 100E in luminaire 10E has a different structure than the first lamp holder 100A in luminaire 10A, and the second lamp holder 200E in luminaire 10E has a different structure than the second lamp holder 200A in luminaire 10A. For example, the second base 120E and the third electrical connection terminal 180 of the first lamp holder 100E are disposed within the space defined by the first base 110 of the first lamp holder 100E, and the second base 220E and the fourth electrical connection terminal 280 of the second lamp holder 200E are disposed within the space defined by the first base 210 of the second lamp holder 200E. Specifically, the third electrical connection terminal 180 is disposed within the mounting space 121E of the second base 120E, and the fourth electrical connection terminal 280 is disposed within the mounting space 221E of the second base 220E. The outer surfaces of both the third base 130E and the third base 230E are curved. It should be noted that the outer surfaces of both the third base 130E and the third base 230E can also be flat, as can be seen from the outer surfaces of the third base 130 and the third base 230. Similarly, the second base 120 of the first lamp holder 100A can also adopt a 100E second base 120E structure, and the second base 220 of the second lamp holder 200A can also adopt a 200E second base 220E structure.

[0104] The differences between luminaire 10E and luminaires 10A and 10D include: the light-emitting component 300C of luminaire 10E is different from the light-emitting component 300A of luminaire 10A and the light-emitting component 300B of luminaire 10D. For example, the difference between light-emitting components 300C and 300B is that the length of the rigid circuit board 331C of light-emitting component 300C along the first direction F1 is greater than the length of the rigid circuit board 331B of light-emitting component 300B along the first direction F1.

[0105] Understandably, luminaire 10E may also include an inner lampshade such as inner lampshade 500A or 500B.

[0106] The same parts and structures in luminaire 10E as those in luminaire 10A and luminaire 10D are marked with the same symbols. For details, please refer to the above descriptions of luminaire 10A and luminaire 10D. They will not be repeated here.

[0107] In other alternative embodiments, one of the lamp holders in luminaire 10E can be replaced with one of the lamp holders in luminaire 10A or one of the lamp holders in luminaire 10D.

[0108] Please continue to refer to this. Figure 31 In the embodiments of this application above, the outer diameter D3 of the main body 430 in the outer lamp cover 400A can be equal to the outer diameter of the first base of any lamp holder. For example, the outer diameter D1 of the first base 110, the outer diameter D2 of the second base 120, and the outer diameter D3 of the main body 430 are all equal.

[0109] It should be noted that the light-emitting components of the lamps in the above embodiments can also be other light-emitting components. The following description, in conjunction with other accompanying drawings, provides an example.

[0110] like Figure 36 As shown, the light-emitting component 300D includes a first electrical connection terminal 310, a second electrical connection terminal 320, and a light-emitting element 330D. The light-emitting element 330D includes a light-emitting component 332D and a first electrical connection interface 338 and a second electrical connection interface 339 directly connected to the light-emitting component 332D. The first electrical connection interface 338 is fixedly connected to the first electrical connection terminal 310, and the second electrical connection interface 339 is fixedly connected to the second electrical connection terminal 320. For example, the light-emitting component 332D may include a light-emitting ribbon. It is understood that this light-emitting component 300D can replace the light-emitting components in the above embodiments. The following description, in conjunction with... Figure 37 This example illustrates the application of the 300D light-emitting component in a luminaire. For instance... Figure 37 As shown, the difference between luminaire 10F and luminaire 10A includes that the light-emitting component 300D in luminaire 10F is different from the light-emitting component 300A in luminaire 10A. It should be noted that luminaire 10F may also include an inner lampshade, such as an inner lampshade 500A. It is understood that when luminaire 10F also includes an inner lampshade, since the light-emitting component 300D does not include a carrier such as a rigid circuit board, the inner lampshade is connected to the first lamp holder 100A and the second lamp holder 200A.

[0111] like Figure 38 , Figure 39 and Figure 40As shown, the light-emitting component 300E includes a first electrical connection terminal 310, a second electrical connection terminal 320, and a light-emitting element 330E. The light-emitting element 330E includes a rigid circuit board 331E, a flexible circuit board 333, and a plurality of light-emitting components 332 disposed on the flexible circuit board 333. The flexible circuit board 333 surrounds the rigid circuit board 331E. The light-emitting component 300E also includes a support member 334. The inner side of the flexible circuit board 333 is attached to the support member 334, and the light-emitting components 332 are disposed on the outer side of the flexible circuit board 333. The support member 334 and the rigid circuit board 331E are connected. For example, the rigid circuit board 331E includes a first limiting structure 3311E and a second limiting structure 3312E disposed on one of its sides, such as the first side 3303E. The first limiting structure 3311E and the second limiting structure 3312E together define a limiting groove 3313E. A portion of the support member 334 is disposed within the limiting groove 3313E and is limited by the first limiting structure 3311E and the second limiting structure 3312E to achieve connection with the rigid circuit board 331E. The first limiting structure 3311E is located near the first end 3301E of the rigid circuit board 331E, and the second limiting structure 3312E is located near the second end 3302E of the rigid circuit board 331E. It should be noted that the first limiting structure 3311E and the second limiting structure 3312E can also be provided on the second side 3304E, or the first limiting structure 3311E and the second limiting structure 3312E can be provided on both sides of the rigid circuit board 331E, for example, as shown in the reference. Figure 26 The rigid circuit board 331B shown will not be described in detail here. It is understood that the light-emitting component 300E can replace the light-emitting components in the above embodiments. The following section, in conjunction with... Figure 41 This example illustrates the application of the light-emitting component 300E in a luminaire. For instance... Figure 41 As shown, the differences between luminaire 10G and luminaire 10A include the different light-emitting components 300E and 300A in luminaire 10G. It should be noted that luminaire 10G may also include an inner lampshade, such as an inner lampshade 500A. Understandably, when luminaire 10G includes an inner lampshade, the flexible circuit board 333 in the light-emitting component 300E surrounds the rigid circuit board 331E, making it difficult to directly fix the inner lampshade to the rigid circuit board 331E. Therefore, the inner lampshade is connected to both the first lamp holder 100A and the second lamp holder 200A.

[0112] The structure of the outer lamp cover in this application is not limited to the structure of the outer lamp cover 400A. The following describes the structure in conjunction with... Figure 42 and Figure 43 An example is provided.

[0113] like Figure 42 and Figure 43As shown, the outer lampshade 400B includes a first connecting portion 410B, a second connecting portion 420B, and a main body portion 430B. A first external connecting structure 411B is provided on the outer side of the first connecting portion 410B, and a second external connecting structure 421B is provided on the outer side of the second external connecting portion 420B. The outer lampshade 400B also includes a storage space 403, and a first opening 401B and a second opening 402B communicating with the storage space 403. In this embodiment, combined with... Figure 31 The maximum outer diameter D4 of the main body 430B of the outer lamp cover 400B is greater than the outer diameter D1 of the first base, such as the first base 110, and the maximum outer diameter D4 of the main body 430B of the outer lamp cover 400B is greater than the outer diameter D2 of the first base, such as the first base 210. It is understood that this outer lamp cover 400B can replace the outer lamp cover 400A in the above embodiments. The following is in conjunction with... Figure 44 and 45 This example illustrates the application of the outer lampshade 400B in a luminaire. For example... Figure 44 As shown, the differences between luminaire 10H and luminaire 10A include the different outer lampshade 400B in luminaire 10H and the different outer lampshade 400A in luminaire 10A. For example... Figure 45 As shown, the differences between luminaire 10I and luminaire 10D or luminaire 10E include that the outer lampshade 400B in luminaire 10I is different from the outer lampshade 400A in luminaire 10D or luminaire 10E.

[0114] like Figure 46 , Figure 47 , Figure 48 , Figure 49 and Figure 50As shown, the luminaire (10J, 10K, 10L, 10M, 10N) includes M outer lamp covers, M light-emitting components, and 2M lamp holders, where M is greater than 1. The luminaire (10J, 10K, 10L, 10M, 10N) includes at least two light-emitting units (11J, 11K, 11L, 11M, 11N), which are connected in series to form a series lamp string structure (1000J, 1000K, 1000L, 1000M, 1000N). The luminaire (10J, 10K, 10L, 10M, 10N) is arranged in a series lamp string structure (1000J, 1000K, 1000L, 1000M, 1000N). In the series-connected lamp string structure (1000J, 1000K, 1000L, 1000M, 1000N), two adjacent outer lamp covers are connected by two lamp holders. The individual light-emitting devices (11J, 11K, 11L, 11M, 11N) can refer to luminaires 10A-10I in the above embodiments. For example, individual light-emitting device 11J can refer to luminaires 10A, 10B, 10C, 10F, or 10G; individual light-emitting device 11K can refer to luminaires 10D or 10E; individual light-emitting device 10M can refer to luminaire 10H; and individual light-emitting device 10N can refer to luminaire 10I.

[0115] like Figure 46 , Figure 47 , Figure 49 and Figure 50 As shown, two lamp holders are provided between two adjacent outer lamp covers, and the two lamp holders located between the two adjacent outer lamp covers are connected by wires.

[0116] like Figure 48 As shown, two lamp holders (100F, 200F) are provided between two adjacent outer lamp covers. The two lamp holders (100F, 200F) located between two adjacent outer lamp covers are directly fixed and seamlessly connected.

[0117] The luminaire (10J, 10K, 10L, 10M, 10N) also includes an electrical connection component 12 and a package component 13. The electrical connection component 12 is connected to one of the light-emitting devices (11J, 11K, 11L, 11M, 11N). For example, if the electrical connection component 12 is connected to the light-emitting device (11J, 11K, 11L, 11M, 11N) at the first end, the electrical connection component 12 can be connected to a power source to supply power to each light-emitting device (11J, 11K, 11L, 11M, 11N). The encapsulation component 13 is connected to one of the light-emitting device units (11J, 11K, 11L, 11M, 11N). For example, the encapsulation component 13 is connected to the light-emitting device unit (11J, 11K, 11L, 11M, 11N) at the tail end and encapsulates the extension of the light-emitting device unit (11J, 11K, 11L, 11M, 11N) at the tail end, thereby encapsulating the wire located in the extension.

[0118] An alternative embodiment, such as Figure 51 , Figure 52 and Figure 53 As shown, any two electrical connection terminals can refer to electrical connection terminal 1 and electrical connection terminal 2. For example, the first electrical connection terminal 310 and the third electrical connection terminal 180 can refer to electrical connection terminal 1 and electrical connection terminal 2, and the second electrical connection terminal 320 and the fourth electrical connection terminal 280 can refer to electrical connection terminal 1 and electrical connection terminal 2. Electrical connection is achieved by the rotatable insertion of electrical connection terminals 1 and 2 relative to axis P2, and separation is achieved by the rotatable separation of electrical connection terminals 1 and 2 relative to axis P2.

[0119] Among them, electrical connection terminal 1 and electrical connection terminal 2 are able to be inserted relative to each other, and can be called coaxial terminals.

[0120] Electrical connection terminals 1 and 2 can be plugged in and detached, and an electrical connection is achieved when they are plugged in. Electrical connection terminals 1 and 2 can rotate relative to each other, and can be rotatably plugged in and rotatably detached. Electrical connection terminals 1 and 2 can rotate about the same axis P2, and can rotate relative to axis P2, and can be rotatably plugged in and rotatably detached relative to axis P2.

[0121] For example, electrical connection terminal 1 may include at least two electrodes, and electrical connection terminal 2 may include at least two electrodes. In this embodiment, the number of at least two electrodes in electrical connection terminal 1 is equal to the number of at least two electrodes in electrical connection terminal 2. The at least two electrodes in electrical connection terminal 1 and the at least two electrodes in electrical connection terminal 2 are electrically connected. For example, electrical connection terminal 1 includes a first electrode 101 and a second electrode 102, and electrical connection terminal 2 includes a third electrode 201 and a fourth electrode 202. The first electrode 101 and the third electrode 201 have the same polarity, for example, both are positive, and the first electrode 101 and the third electrode 201 can be electrically connected. The second electrode 102 and the fourth electrode 202 have the same polarity, for example, both are negative, and the second electrode 102 and the fourth electrode 202 can be electrically connected.

[0122] For example, electrical connection terminal 1 further includes an insulating carrier 103, electrical connection terminal 2 further includes an insulating carrier 203, at least two electrodes of electrical connection terminal 1 are insulated on the insulating carrier 103, and at least two electrodes of electrical connection terminal 2 are insulated on the insulating carrier 203.

[0123] For example, at least one of the first electrode 101 and the third electrode 201 can undergo elastic deformation. During the connection process between the electrical connection terminal 1 and the electrical connection terminal 2, at least one of the first electrode 101 and the third electrode 201 will undergo elastic deformation to maintain the stability of the electrical connection between the first electrode 101 and the third electrode 201.

[0124] For example, at least one of the second electrode 102 and the fourth electrode 202 can undergo elastic deformation. During the connection process between the electrical connection terminal 1 and the electrical connection terminal 2, at least one of the second electrode 102 and the fourth electrode 202 will undergo elastic deformation to maintain the stability of the electrical connection between the second electrode 102 and the fourth electrode 202.

[0125] like Figure 54 and Figure 55As shown, the luminaire (10P, 10Q) includes: M outer lamp covers, M light-emitting components, and 2M lamp holders, where M is greater than 3; the luminaire (10P, 10Q) includes at least two series-connected lamp string structures (1000P, 1000Q), and each series-connected lamp string structure (1000P, 1000Q) is electrically connected to the others. Two adjacent outer lamp covers in the series-connected lamp string structure (1000P, 1000Q) are connected by two lamp holders. Each series-connected light string structure (1000P, 1000Q) includes multiple light-emitting device units (11P, 11Q) connected in series. Each series-connected light string structure (1000P, 1000Q) includes at least a first-end light-emitting device unit (11P1, 11Q1) and a last-end light-emitting device unit (11P2, 11Q2). For example, one or more other light-emitting device units (11P, 11Q) can be connected in series between the first-end light-emitting device unit (11P1, 11Q1) and the last-end light-emitting device unit (11P2, 11Q2) of each series-connected light string structure (1000P, 1000Q). The number of light-emitting device units (11P, 11Q) in each series-connected light string structure (1000P, 1000Q) can be set according to requirements, and this application embodiment does not impose any limitations. It should be noted that the individual light-emitting devices at the front end (11P1, 11Q1), the individual light-emitting devices at the rear end (11P2, 11Q2), and other light-emitting devices (11P, 11Q) can all be referenced. Figures 1 to 45 The illustrated lamp structure will not be described in detail in the embodiments of this application. The individual light-emitting devices (11P, 11Q) in each series lamp string structure (1000P, 1000Q) can be the same or different, for example, one or more reference devices... Figure 1 The lamps shown are one or more references. Figure 27 The lamps shown are illustrated. It is understood that the form of each light-emitting device (1000P, 1000Q) in each series lamp string structure (1000P, 1000Q) in the embodiments of this application can be set according to requirements, and the embodiments of this application do not impose any restrictions.

[0126] The luminaire (10P, 10Q) also includes an electrical connection component 12 and a package component 13. The electrical connection component 12 is connected to the first light-emitting device (11P1, 11Q1) of one of the series-connected luminaire structures (1000P, 1000Q). If the electrical connection component 12 is connected to the first light-emitting device (11P1, 11Q1) of the first series-connected luminaire structure (1000P, 1000Q), the electrical connection component 12 can be connected to a power source to supply power to each light-emitting device (11P, 11Q) in each series-connected luminaire structure (1000P, 1000Q). The encapsulation component 13 is connected to the first light-emitting unit (11P1, 11Q1) of one of the series lamp string structures (1000P, 1000Q). For example, the encapsulation component 13 is connected to the first light-emitting unit (11P1, 11Q1) of the last series lamp string structure (1000P, 1000Q) and encapsulates the extension of the first light-emitting unit (11P1, 11Q1) of the last series lamp string structure (1000P, 1000Q), thereby encapsulating the wire located in the extension.

[0127] Among them, such as Figure 54 As shown, the first-end light-emitting unit 11P1 of the series-connected light string structure 1000P of the luminaire 10P includes three extensions, and the same end of the first-end light-emitting unit 11P1 includes two extensions, such as a first extension 1701 and a second extension 1702. A first-end light-emitting unit 11P1 can be connected to the electrical connection component 12 via the first extension 1701, or it can be connected to the second extension 1702 of other first-end light-emitting unit 11P1s. The second extension 1702 of a first-end light-emitting unit 11P1 can be connected to the encapsulation component 13, or it can be connected to the first extension 1701 of other first-end light-emitting unit 11P1s. For example, a lamp holder of the first light-emitting device unit 11P1, such as a first lamp holder, includes two extensions, such as a first extension 1701 and a second extension 1702, both of which are connected to a third body of the first lamp holder. A lamp holder of the first light-emitting device unit 11P1, such as a second lamp holder, includes an extension that is connected to the extensions of other light-emitting device units 11P.

[0128] Among them, such as Figure 54As shown, the tail-end light-emitting device 11P2 of each string of connected light strings 1000P in the luminaire 10P includes an extension, and the distal end of the tail-end light-emitting device 11P2 does not include the extension. For example, a lamp holder of the tail-end light-emitting device 11P2, such as a first lamp holder, includes an extension and is connected to a third body of the first lamp holder; and a lamp holder of the tail-end light-emitting device 11P2, such as a second lamp holder, does not have an extension, and the third body of the second lamp holder is closed. In other optional embodiments, the tail-end light-emitting device 11P2 may only have one lamp holder, such as only including a first lamp holder without a second lamp holder, or it can be understood that the second lamp holder and the outer lamp cover are integrated.

[0129] Among them, such as Figure 54 As shown, the luminaire 10P also includes a suspension member 14, which is capable of suspending the luminaire 10P. Exemplarily, a single-unit light-emitting device 11P1 is connected to a suspension member 14. Exemplarily, the suspension member 14 can be directly connected to the outer side of the third body of a lamp holder, such as a first lamp holder, of the single-unit light-emitting device 11P1. Exemplarily, the suspension member 14 can be disposed between the first extension 1701 and the second extension 1702.

[0130] For example, the suspension component 14 has an O-shaped structure.

[0131] Among them, such as Figure 55 As shown, the tail-end light-emitting device unit 11Q2 of each series-connected light string structure 1000Q of the luminaire 10Q includes an extension, and the distal end of the tail-end light-emitting device unit 11Q2 does not include the extension. For example, a lamp holder of the tail-end light-emitting device unit 11Q2, such as a first lamp holder, includes an extension and is connected to a third body of the first lamp holder, and a lamp holder of the tail-end light-emitting device unit 11Q2, such as a second lamp holder, does not have an extension, and the third body of the second lamp holder is closed. In other optional embodiments, the tail-end light-emitting device unit 11Q2 may only have one lamp holder, such as only including a first lamp holder without a second lamp holder, or it can be understood that the second lamp holder and the outer lamp cover are integrated.

[0132] Among them, such as Figure 55As shown, the luminaire 10Q also includes a suspension member 15, which is capable of suspending the luminaire 10Q. Exemplarily, a single-ended light-emitting device 11Q1 is connected to a suspension member 15. Exemplarily, a transition member 16 may be connected between the suspension member 15 and the single-ended light-emitting device 11Q1. Exemplarily, a suspension member 15 and a transition member 16 are connected, and the transition member 16 is connected to the single-ended light-emitting device 11Q1. Multiple transition members 16 are connected sequentially, one of which is also connected to an electrical connection member 12, another of which is also connected to an encapsulation member 13, wherein at least one transition member 16 is connected to two adjacent other transition members 16.

[0133] For example, the transition component 16 has a T-shaped structure.

Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.

Assembly step 12: Assemble the first lamp holder and the outer lamp cover; specifically including: first, aligning the first opening of the outer lamp cover with the second electrical connection terminal of the light-emitting component; then, assembling the first connecting part of the outer lamp cover through the light-emitting component with the first base of the first lamp holder; Assembly Step 13: The second lamp holder, the light-emitting component, and the outer lamp cover are assembled simultaneously; specifically, this includes: first, aligning the fourth electrical connection terminal on the second body of the second lamp holder with the second electrical connection terminal of the light-emitting component, and aligning the first body of the second lamp holder with the second connecting part of the outer lamp cover; then, driving the second lamp holder and the outer lamp cover to rotate relative to each other until the connection between the inner connecting structure of the second lamp holder and the outer connecting structure of the second connecting part is completed, thereby realizing the simultaneous assembly of the second lamp holder, the light-emitting component, and the outer lamp cover.

20. An assembly process for a single light-emitting device in a lamp, characterized in that, The light-emitting device in the lamp includes an outer lampshade, a light-emitting component, and two lamp holders as described in claim 1; The assembly process of the light-emitting device in a lamp includes the following assembly steps: Assembly step 31: The first lamp holder and the light-emitting component are partially assembled; specifically, the third electrical connection terminal on the second body of the first lamp holder and the first electrical connection terminal of the light-emitting component are partially assembled; specifically, the third electrical connection terminal and the first electrical connection terminal are partially inserted directly instead of being fully inserted to achieve partial assembly, or the third electrical connection terminal and the first electrical connection terminal are partially inserted with relative rotation instead of being fully inserted to achieve partial assembly. Assembly step 32: The first lamp holder and the outer lamp cover are partially assembled; specifically, the first opening of the outer lamp cover is aligned with the second electrical connection terminal of the light-emitting component; then, the first connecting part of the outer lamp cover passes through the light-emitting component and is partially assembled with the first body of the first lamp holder; specifically, the outer connecting structure on the first connecting part of the outer lamp cover and the inner connecting structure on the first body of the first lamp holder are partially connected to each other rather than fully connected to achieve the partial assembly of the outer lamp cover and the first lamp holder. Assembly step 33: The second lamp holder is partially assembled with the outer lamp cover and the light-emitting component. Specifically, this includes: the first base and the second connecting part of the second lamp holder are partially connected rather than fully connected to achieve partial assembly; and the fourth electrical connection terminal and the second electrical connection terminal on the second base of the second lamp holder are partially directly plugged into each other rather than fully plugged in, or partially plugged in with relative rotation rather than fully plugged in to achieve partial assembly. Assembly step 34: Simultaneously drive the first lamp holder and the second lamp holder to rotate relative to the outer lamp cover; specifically including: the first lamp holder rotates clockwise relative to the outer lamp cover around the axis, and the second lamp holder rotates counterclockwise relative to the outer lamp cover around the axis until the first connecting part and the first base of the first lamp holder are completely connected together, and the second connecting part and the first base of the second lamp holder are completely connected together.
