Description

Technical Field

[0001] The utility model relates to a light source bracket and a lighting fixture, belonging to the technical field of lighting. Background Art

[0002] Due to cost constraints, manufacturers often make light sources smaller, and the soldering pads are also smaller. This makes it difficult for lighting factory workers to solder the power cord. Therefore, the lighting factory often needs to make an adapter plate to solder the light source to. The power cord is soldered to the adapter plate, and after soldering, a light source bracket is required to secure the light source when it is installed in the lamp.

[0003] Currently, on the market, most light source components are installed from the back of the light source bracket, and then the screws are locked and the lines are pressed from the front of the light source bracket. This makes on-site operation inconvenient for workers and requires a long working time.

[0004] In view of this, it is indeed necessary to improve the existing light source bracket and lighting fixture to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a light source bracket, which can realize the front installation of the light source component, is easy to operate and has high installation efficiency.

[0006] To achieve the above objectives, the present invention provides a light source bracket for mounting a light source assembly. The light source bracket includes:

[0007] The bracket body is provided with an installation space, and the bracket body has a front side and a back side;

[0008] The elastic arm is located in the installation space and connected to the bracket body at both ends;

[0009] A snap-fit ​​structure is provided on the elastic arm and protrudes into the installation space;

[0010] Among them, the snap structure is provided with an inclined surface on the front side of the bracket body. Under the elastic force of the elastic arm, the light source assembly is installed into the installation space from the front side of the bracket body along the inclined surface and connected with the snap structure.

[0011] As a further improvement of the present invention, the snap-fit ​​structure includes an abutment portion connected to the elastic arm and a guide portion protruding from the abutment portion toward the installation space, and the inclined surface is provided on the guide portion. This arrangement enables the light source assembly to be quickly installed on the front side of the bracket body.

[0012] As a further improvement to the present invention, a positioning member is provided at least at one end of the elastic arm. The positioning member is located on the back of the bracket body. A gap is left between the plane where the positioning member is located and the plane where the guide portion is located. The light source assembly is restrained within this gap. This arrangement allows the positioning member and the guide portion to jointly restrain the light source assembly.

[0013] As a further improvement to the present invention, the light source bracket also includes a wire pressing structure, located on the front of the bracket body. The wire pressing structure includes a wire threading hole and a retaining post located adjacent to the threading hole. The retaining post has a retaining hole for inserting a fastener. This arrangement allows the light source assembly to be installed and wire pressed simultaneously on the front of the light source bracket, making on-site operation convenient and highly efficient.

[0014] As a further improvement to the present invention, the wire pressing structure also includes an undercut, which is located above the limiting post. The fastener includes a head and a shaft that are connected to each other. The shaft is inserted into the limiting hole, and the side of the head extends into the threading hole to squeeze the wire. The top of the head abuts against the undercut. This arrangement can prevent the fastener from backing out and ensure the wire pressing effect.

[0015] As a further improvement of the present invention, a slot is further provided in the limiting column, which is connected to the limiting hole and divides the limiting column into a side arm close to the threading hole. After the fastener is inserted into the limiting hole, the side arm is squeezed and tilted toward the threading hole to squeeze the wire, further ensuring the wire pressing effect.

[0016] Another object of the present invention is to provide a lighting fixture having the above-mentioned light source bracket.

[0017] To achieve the above-mentioned object, the present invention provides a lighting fixture, comprising:

[0018] heat sink;

[0019] The aforementioned light source bracket is installed on the radiator;

[0020] The light source assembly is mounted on the front of the light source bracket in a manner of contacting the heat sink;

[0021] A lens assembly is connected to the heat sink, and a closed space is formed between the lens assembly and the heat sink;

[0022] The light source bracket and the light source assembly are both accommodated in a closed space.

[0023] As a further improvement of the present invention, the light source assembly includes a base plate, a light source mounted on the base plate, and a power cord mechanically and / or electrically connected to the base plate. When installing the light source assembly, the base plate is squeezed into the installation space along the inclined surface of the snap structure, and the light source contacts the heat sink. This allows for quick installation of the light source assembly on the front side of the light source bracket.

[0024] As a further improvement of the present invention, the radiator is provided with a receiving groove which is arranged through the radiator, and the receiving groove is used for the power line to pass through.

[0025] As a further improvement of the present invention, a fixing hole is provided on the bracket body, and a fixing groove is provided on the radiator that is aligned with the fixing hole to allow a fixing member to be inserted into the fixing hole and the fixing groove to connect the light source bracket and the radiator.

[0026] The beneficial effects of this utility model are as follows: the light source bracket of the utility model achieves fixed installation of the light source assembly by providing an elastic arm and a snap-fit ​​structure on the elastic arm, and the elastic arm exerts little pressure on the light source assembly, which does not cause desoldering.

[0044] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] See also Figure 1-Figure 3 As shown, the utility model discloses a lighting fixture 100, comprising: a radiator 1, a lens assembly 2, a light source bracket 3 and a light source assembly 4. The radiator 1 is covered on the outside of the light source bracket 3 and the light source assembly 4. The lens assembly 2 is connected to the radiator 1, and a closed space 10 is formed between the lens assembly 2 and the radiator 1. The light source bracket 3 is mounted on the radiator 1. The light source assembly 4 is mounted to the front of the light source bracket 3 in contact with the radiator 1. The light source bracket 3 and the light source assembly 4 are both accommodated in the closed space 10. The lighting fixture 100 of the utility model is easy to operate and has high installation efficiency by first mounting the light source bracket 3 on the radiator 1 and then mounting the light source assembly 4 from the front of the light source bracket 3.

[0046] like Figure 4 、 Figure 5 and Figure 8 As shown, the light source bracket 3 is used to install the light source assembly 4, which includes a bracket body 31, an elastic arm 32, a snap-fit ​​structure 33 and a wire pressing structure 34. The bracket body 31 is provided with an installation space 311. The light source assembly 4 is accommodated in the installation space 311, and the bracket body 31 has a front and a back. The back of the bracket body 31 faces the radiator 1 and is fixedly connected to the radiator 1. The elastic arm 32 is located in the installation space 311, and both ends are connected to the bracket body 31, so that the elastic arm 32 is fixed on the bracket body 31 in a suspended state. The elastic arm 32 and the bracket body 31 are integrally formed. The snap-fit ​​structure 33 is provided on the elastic arm 32 and protrudes toward the installation space 311.

[0047] Preferably, two elastic arms 32 are provided opposite to each other. Correspondingly, two snap-fit ​​structures 33 are also provided, corresponding one to one to the two elastic arms 32. When the light source assembly 4 is installed in the installation space 311, the two elastic arms 32 are located on opposite sides of the light source assembly 4. The snap-fit ​​structure 33 is connected with the light source assembly 4 so that the light source assembly 4 is confined within the installation space 311. Of course, in other embodiments, elastic arms 32 can also be added in different directions of the light source bracket 3. As long as the light source assembly 4 can be stably fixed in the installation space 311, no limitation is made here.

[0048] The snap-fit ​​structure 33 is provided with an inclined surface 330 on one side of the front face of the bracket body 31. Under the elastic force of the elastic arm 32, the light source assembly 4 is loaded into the installation space 311 from the front face of the bracket body 31 along the inclined surface 330 and is connected with the snap-fit ​​structure 33. Specifically, the snap-fit ​​structure 33 includes an abutment portion 331 connected to the elastic arm 32 and a guide portion 332 protruding from the abutment portion 331 toward the installation space 311. The inclined surface 330 is provided on the guide portion 332. In this embodiment, the abutment portion 331 is located on the back face of the bracket body 31, that is, the abutment portion 331 is connected to the back face of the elastic arm 32. Of course, in other embodiments, the abutment portion 331 can also be arranged to be located on the front face of the bracket body 31. In this case, the abutment portion 331 and the guide portion 332 are both connected to the front face of the elastic arm 32.

[0049] Light source assembly 4 includes a substrate 41, a light source 42 mounted on substrate 41, and a power cord 43 mechanically and / or electrically connected to substrate 41. Substrate 41 is rectangular and is typically made of a fiberglass printed circuit board (PCB). The size and shape of substrate 41 can be customized based on actual needs and are not limited thereto.

[0050] The light source 42 is arranged to protrude from the substrate 41 and is welded to the side of the substrate 41 facing the radiator 1. In this embodiment, the light source 42 can be a COB light source. When installing the light source assembly 4, the substrate 41 can be quickly squeezed into the installation space 311 along the inclined surface 330 of the guide portion 332. At this time, the substrate 41 abuts against the abutment portion 331, and the light source 42 contacts the radiator 1. The elastic arm 32 applies pressure to the substrate 41 so that the light source 42 is close to the radiator 1. The elastic arm 32 has a deformation space and can play a buffering and shock-absorbing role. The pressure it applies to the substrate 41 is small and will not cause excessive deformation of the substrate 41, resulting in desoldering problems with the light source 42. Moreover, with the help of the elastic force of the elastic arm 32, it can adapt to light source assemblies 4 of various thickness specifications, thereby improving the use range of the light source bracket 3.

[0051] Of course, in other embodiments, the light source 42 can also be flush with the substrate 41. In this case, the light source 42 can be a SMD lamp and soldered to the side of the substrate 41 facing away from the heat sink 1. After the substrate 41 is installed into the installation space 311 from the front of the bracket body 31, it directly contacts the heat sink 1.

[0052] At least one end of the elastic arm 32 is provided with a positioning piece 321. The positioning piece 321 is provided on the back of the bracket body 31. The positioning piece 321 protrudes toward the installation space 311, and there is a gap between the plane where the positioning piece 321 is located and the plane where the guide portion 332 is located. The light source assembly 4 is limited within the gap. Specifically, when the light source assembly 4 is installed, the substrate 41 squeezes the guide portion 332, causing the elastic arm 32 to undergo elastic deformation. After the substrate 41 enters the installation space 311, it is confined within the gap between the positioning piece 321 and the snap structure 33. The light source 42 protrudes and contacts the heat sink 1. The light source assembly 4 can be stably fixed in the installation space 311.

[0053] Of course, in other embodiments, the positioning member 321 and the guide portion 332 can be simultaneously arranged on the front of the bracket body 31, as long as there is a distance between the plane where the positioning member 321 is located and the plane where the guide portion 332 is located to limit the light source assembly 4, and no restriction is made here.

[0054] When there are only two elastic arms 32, a positioning member 321 is provided at both ends of each elastic arm 32, so that the four corners of the light source assembly 4 can be positioned by the four positioning members 321. This arrangement makes the fixation more secure. Of course, in other embodiments, only one positioning member 321 can be provided on each elastic arm 32. In this case, the two positioning members 321 need to be arranged diagonally, so that the light source assembly 4 can also be fixed. If the number of the elastic arms 32 is greater than two, the number of positioning members 321 can be appropriately reduced on the basis of ensuring that the light source assembly 4 is fixed, and there is no restriction here.

[0055] like Figure 6 、 Figure 7 and Figure 9As shown, the light source bracket 3 also includes a wire pressing structure 34, which is integrally arranged with the light source bracket 3. The wire pressing structure 34 is arranged on the front of the bracket body 31. The light source assembly 4 can be installed and wire pressed at the front of the light source bracket 3 at the same time, which is convenient for on-site operation and has high installation efficiency. The wire pressing structure 34 includes a wire threading hole 341 and a limiting column 342 located next to the wire threading hole 341. A limiting hole 343 is provided in the limiting column 342 for the fastener 5 to be inserted to squeeze the power cord 43. A plurality of ribs 3411 are provided on the inner wall of the wire threading hole 341 to increase the friction between the power cord 43 and the inner wall of the wire threading hole 341 when squeezing the power cord 43, thereby ensuring the wire pressing requirement. A receiving groove 11 is provided on the radiator 1. The receiving groove 11 is set through for the power cord 43 to pass through and be connected to the mains to supply power to the light source assembly 4.

[0056] In one embodiment, the wire pressing structure 34 also includes an undercut 344, which is provided above the limiting column 342. The fastener 5 can be a plastic rivet. The fastener 5 includes a head 51 and a shaft 52 that are connected to each other. The shaft 52 is inserted into the limiting hole 343, and the side of the head 51 extends into the threading hole 341 to squeeze the power cord 43. The outer diameter of the shaft 52 is smaller than the inner diameter of the limiting hole 343. When the fastener 5 is inserted into the limiting hole 343, there is a situation of retreat. The top of the head 51 abuts against the undercut 344, which can ensure that the fastener 5 does not retreat.

[0057] In another embodiment, a slot 3421 is further provided in the limiting column 342. The slot 3421 is connected to the limiting hole 343, and divides the limiting column 342 into a side arm 3422 close to the threading hole 341. The outer diameter of the fastener 5 is larger than the inner diameter of the limiting hole 343. After the fastener 5 is inserted into the limiting hole 343, the side arm 3422 is squeezed and tilted toward the threading hole 341 to squeeze the power cord 43. A protrusion 3423 is provided on the side of the side arm 3422 facing the power cord. When the side arm 3422 tilts to squeeze the power cord 43, the protrusion 3423 further squeezes the power cord 43 to ensure the wire pressing requirement.

[0058] like Figure 9 and Figure 10 As shown, in this embodiment, the light source bracket 3 is first fixedly installed on the radiator 1. Specifically, a plurality of fixing holes 312 are provided on the bracket body 31. A plurality of fixing grooves 12 are provided on the radiator 1, which are aligned with the plurality of fixing holes 312, so as to allow the fixing member 6 to be inserted into the fixing hole 312 and the fixing groove 12 to connect the light source bracket 3 and the radiator 1. The fixing member 6 can be a screw, which is not limited. The lens assembly 2 includes a face ring 21 and a lens 22 fixedly connected to the face ring 21. The face ring 21 and the radiator 1 are connected by a snap fastener to form a closed space 10. A plurality of supporting legs 221 are provided on one end of the lens 22 facing the light source assembly 4. The supporting legs 221 are in contact with the substrate 41 and are arranged around the periphery of the light source 42 to achieve light output.

[0059] In summary, the lighting fixture 100 of the present invention first installs the light source bracket 3 on the heat sink 1. The light source bracket 3 then securely mounts the light source assembly 4 by providing an elastic arm 32 and a snap-fit ​​structure 33 on the elastic arm 32. The elastic arm 32 exerts little pressure on the light source assembly 4, preventing desoldering. Furthermore, an inclined surface 330 is provided on the snap-fit ​​structure 33 on the front side of the bracket body 31, allowing the light source assembly 4 to be installed into the installation space 311 from the front of the bracket body 31 along the inclined surface 330, resulting in convenient operation and efficient installation.
