[0036] According to a first aspect of this application, an LED light source assembly 100 is provided. According to a second aspect of this application, an LED luminaire 200 is provided.

[0037] like Figures 1 to 4As shown, the LED light source assembly 100 provided in the embodiment of this application includes an LED light source 20 and a connector 30. The LED light source 20 includes a substrate 21 and an LED structure 22 disposed on the substrate 21. The substrate 21 is provided with a mounting hole 211. The connector 30 includes a body 31 and an elastic body 32. The body 31 includes a plug-in portion 311 and a head 312. The plug-in portion 311 extends along an axis X perpendicular to the substrate 21. The head 312 is connected to one end of the plug-in portion 311. The plug-in portion 311 includes a plug-in body 3111 and at least two sets of hook structures 3114. At least two sets of hook structures 3114 are disposed on the plug-in body 3111, and adjacent sets of hook structures 3114 are spaced apart. The set of hook structures 3114 near the head 312 is spaced apart from the head 312. The insertion body 3111 passes through the elastic body 32 and the mounting hole 211. The elastic body 32 and the substrate 21 are clamped between the head 312 and a set of hook structures 3114 near the head 312, so that the connector 30 engages with the substrate 21, and the LED light source 20 and the connector 30 are assembled into a modular structure. Furthermore, at least one other set of hook structures 3114 away from the head 312 is suspended, so that at least one other set of hook structures 3114 away from the head 312 can be used to connect to the support member 40 to assemble into an LED lamp 200.

[0038] And, as Figure 5 and Figure 6 As shown, the LED lamp 200 provided in the embodiment of this application includes a support member 40 and an LED light source assembly 100 as described above. The support member 40 is provided with an assembly hole 41. At least another set of hook structures 3114 of the connector 30 of the LED light source assembly 100, which is away from the head 312, passes through the assembly hole 41 and hooks onto the support member 40, so that the LED light source assembly 100 and the support member 40 are joined and assembled into the LED lamp 200.

[0039] The LED light source assembly 100 of this application uses a connector 30 to lock and install the LED light source 20. The connector 30 includes a body 31 and an elastic body 32. The body 31 consists of a plug-in portion 311 and a head 312. The plug-in portion 311 includes a plug-in main body 3111 and at least two sets of hook structures 3114 disposed on the plug-in main body 3111. The plug-in main body 3111 passes through the mounting holes 211 of the elastic body 32 and the substrate 21, so that the elastic body 32 and the substrate 21 are clamped between the head 312 and a set of hook structures 3114 near the head 312. This allows the connector 30 to engage with the substrate 21, i.e., the LED light source 20 and the connector 30 are assembled into a modular structure, effectively preventing the connector 30 from being lost. Furthermore, at least one other set of hook structures 3114, away from the head 312, is suspended to lock the LED light source assembly 100 as a whole onto the support member 40 for assembly into an LED lamp 200. In this way, the LED light source assembly 100, which is assembled into a modular structure, can ensure that the connector 30 and the LED light source 20 are always in a connected state, and can be used immediately, thereby improving the production efficiency of assembling and producing LED lamps 200.

[0040] In the LED light source assembly 100 provided in the embodiments of this application, such as Figure 3 and Figure 4 As shown, the LED structure 22 and at least one other set of latching structures 3114, located away from the head 312, are respectively located on both sides of the substrate 21. Thus, when the LED light source assembly 100 is integrally locked onto the support member 40 to assemble the LED lamp 200, the LED structure 22 of the LED light source 20 is located on the side of the substrate 21 facing away from the support member 40. This allows the side of the substrate 21 facing the support member 40 to be as close as possible to the support member 40, preferably with the substrate 21 abutting against the support member 40, at which point the elastic body 32 is clamped between the head 312 and the substrate 21. Therefore, when the LED structure 22 emits light, the heat generated by the LED structure 22 is transferred through the substrate 21 to the support member 40, and then dissipated through the support member 40, thereby contributing to the overall heat dissipation and cooling of the LED light source 20 and effectively preventing abnormal temperature rise of the LED light source 20. Alternatively, in this embodiment, the substrate 21 is suspended relative to the support member 40. In this case, the substrate 21 is sandwiched between the head 312 and the elastic body 32, and the end of the elastic body 32 facing away from the substrate 21 abuts against the support member 40.

[0041] Of course, in some other embodiments of this application, the LED structure 22 and at least another set of latching structures 3114 away from the head 312 can both be located on the same side of the substrate 21 (in this case, at least two sets of latching structures 3114 and the LED structure 22 are both located on the same side of the substrate 21). In this embodiment, when the LED light source assembly 100 is integrally locked onto the support member 40 to assemble into an LED lamp 200, the LED structure 22 of the LED light source 20 faces the support member 40. In order to emit light for illumination, a light-emitting window is provided in the area of ​​the support member 40 facing the LED structure 22 for the light emitted from the LED structure 22 to pass through for illumination. Furthermore, in this embodiment, the LED structure 22 can be inserted through the light-emitting window, so that a portion of the substrate 21 rests against the support member 40. At this time, the elastic body 32 is sandwiched between the head 312 and the substrate 21. When the LED structure 22 emits light, the heat generated by the LED structure 22 is transferred through the substrate 21 to the support member 40, and then dissipated through the support member 40, thereby helping to cool the overall LED light source 20 and effectively preventing abnormal temperature rise of the LED light source 20. Alternatively, in this embodiment, the substrate 21 is suspended relative to the support member 40. In this case, the substrate 21 is sandwiched between the head 312 and the elastic body 32, and the end of the elastic body 32 facing away from the substrate 21 abuts against the support member 40.

[0042] When the LED light source assembly 100 is assembled using a method where the substrate 21 is clamped between the head 312 and the elastic body 32, the diameter of the head 312 is larger than the diameter of the mounting hole 211, and the outer diameter of the elastic body 32 is larger than the diameter of the mounting hole 211. This ensures that the head 312 and the elastic body 32 stably clamp the substrate 21. When the LED light source assembly 100 is assembled using a method where the elastic body 32 is clamped between the head 312 and the substrate 21, the diameter of the head 312 is larger than the diameter of the mounting hole 211, and the outer diameter of the elastic body 32 is larger than the diameter of the mounting hole 211. The head 312 and the substrate 21 can also stably clamp the elastic body 32.

[0043] In some other embodiments of this application, when the LED light source assembly 100 is assembled by using an elastomer 32 clamped between the head 312 and the substrate 21, the diameter of the head 312 can be smaller than the diameter of the mounting hole 211. At this time, the diameter of the head 312 must be greater than the diameter of the elastomer 32 and the outer diameter of the elastomer 32 must be greater than the diameter of the mounting hole 211, so that the head 312 and the substrate 21 can stably clamp the elastomer 32.

[0044] Preferably, in the LED light source assembly 100 of this application, the assembly is performed by using an elastomer 32 clamped between the head 312 and the substrate 21, and the diameter of the head 312 is larger than the diameter of the mounting hole 211.

[0045] like Figures 1 to 4 As shown, the LED light source assembly 100 provided in the embodiments of this application includes a first elastic arm 3112 and a second elastic arm 3113, both of which have elastic deformation capability. Furthermore, as... Figures 1 to 4 As shown, each set of hook structures 3114 includes a first hook 3115 and a second hook 3116. The first hook 3115 of each set of hook structures 3114 is disposed on the first spring arm 3112, and the second hook 3116 of each set of hook structures 3114 is disposed on the second spring arm 3113. The first hook 3115 and the second hook 3116 of the same set extend away from each other. When the insertion body 3111 is inserted into the mounting hole 211 of the elastic body 32 and the substrate 21, the first spring arm 3112 and the second spring arm 3113 are squeezed, so that the first spring arm 3112 and the second spring arm 3113 move closer to each other, so that the distance between the end of the first hook 3115 and the end of the second hook 3116 of each set of hook structures 3114 becomes smaller, so that each set of hook structures 3114 can pass smoothly through the through hole of the elastic body 32 and the mounting hole 211 of the substrate 21. Then, the first elastic arm 3112 and the second elastic arm 3113 are released. Under their respective elastic forces, the first elastic arm 3112 and the second elastic arm 3113 move away from each other until they return to their unelastic deformation state. At this time, the first hook 3115 and the second hook 3116 of a set of hook structures 3114 near the head 312 hook the elastic body 32, so that the connector 30 is joined to the substrate 21, and the LED light source 20 and the connector 30 are assembled into a modular structure.

[0046] Furthermore, the insertion body 3111 is further inserted into the mounting hole 41 of the support member 40. At this time, the first elastic arm 3112 and the second elastic arm 3113 are squeezed by the hole wall of the mounting hole 41 and move closer to each other until at least another set of hook structures 3114 away from the head 312 passes through the mounting hole 41. When at least another set of hook structures 3114 away from the head 312 passes through the mounting hole 41, the first elastic arm 3112 and the second elastic arm 3113 move away from each other under their respective elastic forces until they return to a state without elastic deformation. Then, the first hook 3115 and the second hook 3116 of the at least another set of hook structures 3114 away from the head 312 hook onto the support member 40, so that the LED light source assembly 100 and the support member 40 are joined and assembled into an LED lamp 200. Furthermore, the support member 40, the substrate 21, the elastomer 32, and the head 312 are sequentially stacked and compressed along the extension direction of the axis X. Since the elastomer 32 has elastic deformation capability, the elastomer 32 is compressed, thereby absorbing the assembly tolerances of the hook structure 3114, the support member 40, the substrate 21, the elastomer 32, and the head 312 along the extension direction of the axis X, so as to complete the installation work more reliably.

[0047] In the connector of the LED light source assembly 100 of this application, the latching structures 3114 are in two sets spaced apart. One set of latching structures 3114 is close to and spaced apart from the head 312, while the other set of latching structures 3114 is away from the head 312 and is used to connect to the support member 40. Furthermore, as... Figure 2 As shown, in the set of hook structures 3114 near the head 312, the distance between the end of the first hook 3115 and the end of the second hook 3116 is L1, and in at least another set of hook structures 3114 away from the head 312, the distance between the end of the first hook 3115 and the end of the second hook 3116 is L2, where L1 ≥ L2. Furthermore, as... Figure 6 As shown, in the LED lamp 200 provided in the embodiment of this application, the support member 40 is further provided with a groove 42 recessed away from the LED light source 20. The mounting hole 41 is provided at the bottom of the groove 42. A set of hook structures 3114 near the head 312 are at least partially accommodated in the groove 42, and the substrate 21 abuts against the support member 40 and compresses the elastic body 32. That is, the groove diameter of the groove 42 is greater than L1, L1 is greater than the diameter of the mounting hole 211, the diameter of the mounting hole 211 is smaller than the outer diameter of the elastic body 32, and L2 is greater than the diameter of the mounting hole 41.

[0048] In the embodiments of this application, the body 31 of the connector 30 is a one-piece molded component. Further, the body of the connector 30 can be a component integrally molded from metal material using a stamping process, or it can be a component integrally molded from plastic using an injection molding process. And the elastomer 32 is one of a rubber pad, a silicone pad, or a coil spring.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
