Description

Technical Field

[0001] The present application relates to the field of lighting technology, and in particular to a light source bracket and a lamp. Background Art

[0002] As the name suggests, the light source bracket is a type of bracket-type auxiliary device used to install the light source. At present, the light source module and lens installed on the radiator are fixed by the light source bracket. The light source module is mostly clamped between the radiator and the light source bracket, and the lens is mostly installed on the light source bracket.

[0003] When the light source module was tested at the factory, the yield met the standard, but after assembly, the yield decreased. After testing, it was found that this phenomenon was mostly caused by a malfunction of the light source module. Summary of the Invention

[0004] In order to reduce the failure rate of the light source module, the present application provides a light source bracket and a lamp.

[0005] The light source bracket and lamp provided in this application adopt the following technical solutions:

[0006] In a first aspect, the present application provides a light source bracket, comprising:

[0007] A circuit board, wherein the circuit board is provided with a light source hole and a through hole, wherein the light source hole is used to conduct light emitted by the light source module, and the circuit board is provided with a first electrode, wherein the first electrode is used to contact and conduct with the electrode on the light source module;

[0008] a lens holder, the lens holder being provided with a light exit hole opposite to the light source hole and an inserting portion capable of passing through the through hole, the inserting portion being provided with a protruding portion at one end passing through the through hole, the protruding portion abutting against a side of the circuit board facing away from the lens holder to limit the axial position of the lens holder;

[0009] a clamping portion, wherein a second electrode electrically connected to the first electrode is provided on the clamping portion, and the clamping portion is used to clamp an external lead so that the lead is in contact and electrically connected to the second electrode; and

[0010] The positioning portion and the matching portion are respectively arranged on the circuit board and the lens holder. The positioning portion matches the matching portion to limit the circumferential movement of the lens holder.

[0011] By adopting the above technical solution, when installing the light source bracket, the light source is installed in the light source hole, the electrode on the light source module contacts and conducts with the first electrode on the circuit board, and the light source module can be connected to the circuit board without welding. At the same time, the clamping part clamps the external lead, so that the external lead contacts and conducts with the second electrode. Since the first electrode is connected with the second electrode, the light source module can be connected to the external circuit without welding, thereby avoiding the heat source during contact welding of the light source module and reducing the failure rate of the light source module; the lens frame is axially fixed to the circuit board by cooperating with the through-hole on the circuit board through the plug-in part and the protruding part, and the circuit board and the lens frame are circumferentially fixed by setting the cooperating part to cooperate with the positioning part on the circuit board.

[0012] Optionally, the clamping portion includes two terminals, and the terminals include:

[0013] A substrate, wherein the substrate is provided with a threading hole for external leads to pass through;

[0014] Two protruding sections are formed protruding from opposite ends of the base plate toward one side;

[0015] Two connecting sections are formed by bending inward from the protruding section; and

[0016] Two clamping sections are formed by bending from the end of the connecting section away from the protruding section toward a side away from the substrate. The two clamping sections are arranged opposite to each other to clamp the external lead.

[0017] By adopting the above-mentioned technical solution, the clamping part includes two terminals arranged on the circuit board, and the two terminals respectively clamp an external lead. The external lead passes through the wire hole and then passes through the clamping section. Since the external lead passes through the clamping section, the clamping section will produce elastic deformation. Therefore, after the external lead passes through the clamping section, the clamping section will clamp the external lead to achieve conduction between the external lead and the light source module.

[0018] Optionally, the connecting section is flat Z-shaped, having a first connecting section connected to the protruding section and a second connecting section connected to the clamping section. The first connecting section and the second connecting section are connected by a third connecting section, and the angles between the third connecting section and the first connecting section and the second connecting section are all obtuse angles; the first connecting section is fixedly connected to the circuit board.

[0019] By adopting the above technical solution, the first connecting section does not contact the substrate, so the connection between the first connecting section and the protruding section is not easily broken; since the angles between the third connecting section and the first connecting section and the second connecting section are all obtuse angles, the clamping force of the clamping section can be increased.

[0020] Optionally, opposite sides of the ends of the two clamping sections away from the base plate are concave to form threading seams.

[0021] By adopting the above technical solution, when the lead wire passes through the terminal through the wire threading hole, the wire threading seam can reduce the rotation angle of the clamping section, making the lead wire easier to insert.

[0022] Optionally, the positioning portion is a card slot provided on the circuit board, and the mating portion is a card block provided on the lens holder. The card slot is rotationally engaged with the card block, and a limit block is provided in the middle of the card slot. After the card slot is rotationally engaged with the card block, the limit block is used to limit the card block to limit the circumferential movement of the lens holder.

[0023] By adopting the above technical solution, the card slot and the card block cooperate with each other, and the circuit board and the lens holder are fixed after rotation and engagement. At the same time, a limit block is provided in the middle of the card slot. After rotation and engagement, the limit block limits the card block, thereby limiting the circumferential movement of the lens holder.

[0024] Optionally, the plug-in portion and the perforation are rotationally engaged, the widths of the two ends of the perforation are inconsistent, the wider end of the perforation is for the protruding portion to be inserted, and after the plug-in portion and the perforation are rotationally engaged, the protruding portion is located at the narrower end of the perforation and abuts against the circuit board.

[0025] By adopting the above technical solution, after the protruding portion is inserted from the wider end of the through-hole, and the plug-in portion is rotated and engaged with the through-hole, the protruding portion abuts against the circuit board at the narrower end of the through-hole, thereby limiting the lens holder in the axial direction.

[0026] Optionally, the second electrode is provided on the side wall of the perforation, and after the plug-in portion is rotated and engaged with the perforation, the side wall of the perforation and the plug-in portion form the clamping portion, which clamps the lead wire so that the lead wire is in contact and conductive with the second electrode.

[0027] By adopting the above technical solution, the external lead can be placed in the through-hole, and after the plug-in portion is rotated and engaged with the through-hole, the external lead can be clamped. The second electrode is located on the side wall of the through-hole, and the external lead is in contact and conductive with the second electrode. Since the second electrode is in contact with the first electrode, the first electrode is in contact and conductive with the positive and negative poles of the light source module, thereby achieving conductive connection between the light source module and the external lead, reducing the structural complexity of the circuit board and reducing the failure rate.

[0028] Optionally, the side surfaces adjacent to the plug-in portion and the protruding portion are transitioned through an inclined surface.

[0029] By adopting the above technical solution, the diameter of the plug part close to the protruding part gradually increases. When the plug part is rotated and engaged with the through hole, the circuit board and the lens frame gradually approach each other, making the connection between the circuit board and the lens frame more stable.

[0030] In a second aspect, the present application also provides a lamp, comprising the light source bracket as described above.

[0031] By adopting the above technical solution and using the above light source bracket, the failure rate of the lamp can be reduced and its service life can be increased.

[0032] Optionally, also include:

[0033] a radiator, the light source bracket being mounted on the radiator;

[0034] A lens is mounted on the lens holder.

[0035] By adopting the above technical solution, the radiator is used to dissipate heat from the light source during operation, and the lens is used to scatter or focus light emitted by the light source.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] 1. The first electrode is connected to the electrode on the light source module, and the terminal is used to clamp the external lead, so that the external lead is connected to the second electrode, and the light source module can be connected to the external circuit without welding;

[0038] 2. When the circuit board and the lens bracket are rotated and clamped, the external leads are clamped by the plug-in part and the perforated rotation clamp, which reduces the failure rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The following will be combined with the Figure 1-11 , clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0054] The present application discloses a lamp comprising a light source holder. The lamp can be a lighting fixture, a signal light, a medical lamp, or other luminous fixture. In an optional embodiment, the lamp further comprises a heat sink for mounting the light source holder, and a lens mounted on a lens holder 2. The heat sink dissipates heat from the light source during operation, and the lens scatters or focuses light emitted by the light source.

[0055] Example 1

[0056] The present application discloses a light source bracket, referring to Figure 1 The light source bracket includes a circuit board 1, a lens frame 2, a clamping part, a positioning part and a matching part.

[0057] Reference Figure 1 A light source hole 11 is provided on the circuit board 1, and the light source module is installed in the light source hole 11. The light source hole 11 is used to conduct the light emitted by the light source module. The circuit board 1 is also provided with a first electrode 13 protruding into the light source hole 11. It can be understood that the first electrode 13 is used to conduct with the electrode on the light source module, thereby realizing conduction between the light source module and the circuit board 1.

[0058] Currently, the light source brackets on the market need to be connected to the light source module by welding. However, during welding, the light source module will be close to the heat source, causing the colloid in the light source module to expand due to heat. After welding is completed, the colloid will dissipate heat and shrink. This thermal expansion and contraction process will affect the gold wire in the light source module. Moreover, the existing light source bracket needs to be welded at least twice to achieve conduction with the circuit. The colloid in the light source module undergoes multiple thermal expansion and contraction, which will affect the life of the gold wire encapsulated in the colloid, shorten the service life of the luminous gold wire, and even cause the gold wire to break, thereby increasing the failure rate of the light source module.

[0059] In this embodiment, the light source module can be connected to the circuit board 1 without soldering, thereby reducing the failure rate of the light source module.

[0060] The first electrode 13 may be elastic or non-elastic. In this embodiment, the first electrode 13 is an elastic electrode sheet. This configuration can buffer the first electrode 13 from hard collisions with electrodes on the light source module during installation or use, thereby reducing the failure rate. In other embodiments, the first electrode 13 can also be an elastic conductive member such as a conductive spring or a conductive reed.

[0061] Reference Figure 2 and Figure 3 A second electrode 14 that is conductive with the first electrode 13 is provided in the clamping portion, a copper plate that is conductive with the first electrode 13 is provided inside the circuit board 1, and the second electrode 14 is conductive with the copper plate. The clamping portion is used to clamp the external lead so that the external lead is conductive with the second electrode 14. It can be understood that at this time, the light source module is conductive with the external circuit. With such a setting, the light source module can be conductive with the external circuit without welding, thereby reducing the failure rate of the light source module.

[0062] Reference Figure 2 and Figure 3 The clamping portion includes two terminals 3, both of which are located on the circuit board 1, and the terminals 3 are made of conductive material. In this embodiment, the terminals 3 are made of metal and are conductive to the copper plate in the circuit board 1. The two terminals 3 respectively clamp an external lead.

[0063] Reference Figure 4 The terminal 3 includes a substrate 31, two protruding sections 32, two connecting sections 33 and two clamping sections 34. The two protruding sections 32 are formed by protruding from opposite ends of the substrate 31 toward one side, the two connecting sections 33 are formed by bending inward from the protruding sections 32, and the two clamping sections 34 are formed by bending from the ends of the connecting sections 33 away from the protruding sections 32 toward the side away from the substrate 31, and the two clamping sections 34 are arranged opposite to each other, and the ends of the two clamping sections 34 away from the substrate 31 are abutted against each other. At the same time, a threading hole 311 is provided on the substrate 31, and the external lead is inserted through the threading hole 311 and then passes through the clamping section 34. When passing through the clamping section 34, the clamping section 34 will produce elastic deformation, and the clamping section 34 will clamp the external lead.

[0064] With this arrangement, when inserting an external lead, the two clamping sections 34 can be easily pushed apart, thereby enabling the lead to be inserted between the clamping sections 34. However, when the lead is pulled out, the friction between the lead and the clamping sections 34 will cause the clamping sections 34 to rotate, which can increase the clamping force between the two clamping sections 34, thereby increasing the friction between the lead and the clamping sections 34, and the clamping sections 34 can clamp the lead tighter.

[0065] Reference Figure 4The opposite sides of the two clamping sections 34, facing away from the substrate 31, are concave, forming threading slots 341. When an external lead passes through the clamping sections 34, the threading slots 341 facilitate insertion of the lead between the clamping sections 34 and enhance the clamping force of the clamping section on the lead. In other embodiments, the clamping sections 34 can also abut against leads of varying thicknesses.

[0066] In this embodiment, a through hole is provided on the circuit board 1, the clamping section 34 is located in the through hole, and the substrate 31, the protruding section 32, and the connecting section 33 are all located outside the circuit board 1. In other embodiments, the terminal 3 can be integrated in the circuit board 1, and the external lead first passes through the through hole and then through the wire hole 311 of the terminal 3, and then is clamped by the clamping section 34.

[0067] Reference Figure 3 The connecting section 33 is flat and Z-shaped. The connecting section 33 has a first connecting section 331 connected to the protruding section 32 and a second connecting section 332 connected to the clamping section 34. The first connecting section 331 and the second connecting section 332 are connected by a third connecting section 333. The angle between the third connecting section 333 and the first connecting section 331 is an obtuse angle, and the angle between the third connecting section 333 and the second connecting section 332 is also an obtuse angle; the first connecting section 331 is fixedly connected to the circuit board 1.

[0068] Since the connecting section 33 is in a flat Z-shape and the second connecting section 332 is against the substrate 31, it can be understood that the second connecting section 332 does not contact the circuit board 1. With this arrangement, when the external lead is inserted into the terminal 3, the part where the clamping section 34 is connected to the second connecting section 332 will not contact the wall of the through hole. The clamping section 34 will not generate stress with the wall of the through hole due to rotation, thereby damaging the circuit board 1 or the terminal 3, thereby reducing the failure rate.

[0069] Since the first connecting section 331 and the third connecting section 333 are both far away from the substrate 31, the second connecting section 332 is fixedly connected to the substrate 31. Compared with the case where the clamping section 34 is directly connected to the first connecting section 331, this arrangement can make the clamping section 34 tilted at a larger angle relative to the substrate 31. After the lead passes through, the clamping section 34 rotates at a larger angle, so that the two clamping parts generate a greater clamping force on the lead. At the same time, since the clamping section 34 tilts at a larger angle relative to the substrate 31, when the lead is pulled out, the greater the force along the clamping section 34, the clamping section 34 can clamp the lead more firmly.

[0070] Lens holder 2 also has a lens slot 24. A light exit hole 21, which communicates with the light source, is located at the bottom of lens slot 24. Lens slot 24 is used to mount a lens, and light exit hole 21 is used to transmit light emitted by the light source module to the lens. Circuit board 1 and lens holder 2 can be connected by threaded or snap-fit ​​connections. In this embodiment, the circuit board 1 and lens holder 2 are connected by a rotating snap-fit ​​connection.

[0071] Reference Figure 1 A through-hole 12 is provided on the circuit board 1, and a plug-in portion 22 corresponding to the through-hole 12 is provided on the lens holder 2. A protruding portion 221 is provided at one end of the plug-in portion 22 passing through the through-hole 12. The widths of the two ends of the through-hole 12 are inconsistent. The protruding portion 221 is inserted from the wider end of the through-hole 12. After rotation and engagement, the protruding portion 221 is at the narrower end of the through-hole 12 and abuts against the circuit board 1, thereby limiting the lens holder 2 in the axial direction.

[0072] The side surfaces adjacent to the plug portion 22 and the protruding portion 221 are transitioned through an inclined surface. When the plug portion 22 is rotated and engaged with the through hole 12, the circuit board 1 and the lens frame 2 gradually approach each other, making the connection between the circuit board 1 and the lens frame 2 more stable.

[0073] Reference Figure 1 The circuit board 1 is also provided with a positioning portion, and the lens holder 2 is provided with a mating portion corresponding to the positioning portion, and the positioning portion and the mating portion cooperate. In this embodiment, the positioning portion is a slot 15 provided on the circuit board 1, and the slot 15 passes through the circuit board 1. In other embodiments, the slot 15 may not pass through the circuit board 1. The mating portion is a block 23 provided on the lens holder. The slot 15 is rotatably engaged with the block 23. At the same time, a stopper 151 is provided in the middle of the slot 15. The stopper 151 is used to limit the position of the block 23 after rotational engagement, thereby limiting the circumferential movement of the lens holder 2. In other embodiments, the slot 15 and the block 23 have an interference fit, and the friction between them limits the block 23, thereby limiting the circumferential movement of the lens holder 2.

[0074] The implementation principle of a light source bracket in an embodiment of the present application is: a light source hole 11 is provided on the circuit board 1, and an elastic electrode sheet extending into the light source hole 11 is provided, so that the light source module and the circuit board 1 can be connected without welding. At the same time, a metal terminal 3 connected to the elastic electrode sheet is also provided on the circuit board 1. The terminal 3 is used to clamp the external lead, so that the circuit board 1 and the external lead can be connected without welding, thereby realizing the connection between the light source module and the external lead. With this arrangement, the light source module can be connected to the external circuit without contacting the heat source, which can reduce the failure rate of the light source module.

[0075] Example 2

[0076] Reference Figure 9-11 The difference between Example 2 and Example 1 is that the second electrode 14 is provided on the side wall of the through hole 12. After the plug-in portion 22 is rotated and engaged with the through hole 12, the side wall of the through hole 12 and the plug-in portion 22 form a clamping portion to clamp the lead so that the lead is in contact with the second electrode 14 and is conductive.

[0077] Reference Figure 5-8The end of the plug-in portion 22 passing through the through-hole 12 is provided with a protruding portion 221 parallel to the direction of the circuit board 1, and a first groove 2211 is provided on the protruding portion 221. The circuit board 1 is provided with a second groove 16 corresponding to the first groove 2211. After the plug-in portion 22 is rotated and engaged, the first groove 2211 and the second groove 16 are closed to form an accommodating hole 4, and a second electrode 14 is provided on the side wall of the through-hole 12. The accommodating hole 4 can clamp the external lead to achieve electrical connection between the external lead and the second electrode 14, thereby achieving electrical connection between the light source module and the outside.

[0078] With this arrangement, on the one hand, there is no need to set up additional terminals 3, which makes the structure of the light source bracket simpler and reduces the failure rate of the light source bracket. On the other hand, the external leads can be set parallel to the circuit board 1 without bending, which can reduce the probability of external lead breakage and reduce the overall failure rate.

[0079] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
