Description

Technical Field

[0001] This invention relates to the field of lighting equipment technology, and in particular to an LED lamp, its assembly method, and its application. Background Technology

[0002] LED lights are typically composed of multiple LEDs connected in series or parallel to form a light strip structure, which is then assembled into a housing. Due to their advantages such as energy saving, long lifespan, and high brightness, they are widely used in various industries. When an LED light is damaged, it is only necessary to disassemble the housing and remove the light strip for replacement, making maintenance relatively convenient. This makes them increasingly common and widely used in various devices.

[0003] An existing invention patent with authorization publication number CN108954023B proposes a low-cost LED lamp. The LED lamp is an LED lamp installed on a lighting fixture that can install a fluorescent lamp, and has: a plurality of conductive sheets arranged with intervals; a plurality of LED elements arranged across the conductive sheets that are adjacent to each other with intervals and electrically connecting the adjacent conductive sheets; and a tube that houses the plurality of conductive sheets and the plurality of LED elements on the lighting fixture side.

[0004] As described in the above technical solution, an LED light strip is constructed using multiple conductive sheets and LED components. Currently, LED light strips are commonly used as the lighting component in lighting fixtures. However, when some LED beads are damaged, the entire strip is usually replaced to avoid affecting brightness and performance. For example, in large lighting fixtures, the cost of using a one-meter-long high-brightness light strip can be tens of yuan or even higher. This results in high maintenance costs and a waste of resources. Therefore, it is necessary to improve the structure of existing LED lights. Summary of the Invention

It also engages with the slot to position the cover plate. At the same time, the second conductive electrode abuts against the conductive plug plate to enable the power board to supply power to the lamp assembly.

[0046] In another aspect, the present invention provides an application of the above-mentioned LED light for use in refrigerators, freezers, wine cabinets or display cases.

[0047] The LED lamp, its assembly method, and its application of the present invention have the following advantages over the prior art:

[0048] (1) By setting lamp slots and plate slots in the housing, multiple lamp groups can be arranged around the plate slots, and the lamp groups can be fixed and electrically connected to the power board through guide rods. This makes the LED lamp convenient to assemble. The guide rods are multi-purpose, simplify the overall structure, and allow individual lamp groups to be disassembled. In case of partial damage, it is not necessary to replace the entire lamp group, which reduces the maintenance cost during application and reduces resource waste.

[0049] (2) The housing is provided with a socket and a through slot. The first conductive electrode in the lamp assembly passes through the lamp housing. After the guide rod is inserted into the housing, the guide rod can cooperate with the positioning slot on the lamp housing to fix the lamp assembly. The guide rod is also connected to the power board to achieve electrical connection. When replacing the lamp assembly, you only need to pull out the guide rod. Not only can the lamp assembly be disassembled, but the electrical connection is also disconnected at the same time, which improves the safety of disassembly and assembly.

[0050] (3) The guide rod is equipped with an inner cylinder, an end cylinder and an outer cylinder. The outer cylinder is a conductive part between the lamp assembly and the power board, and the inner cylinder is made of metal. In this way, the airflow can enter the inner cylinder through the end cylinder to dissipate heat from the outer cylinder, which is conducive to ensuring the stable operation of the LED lamp and can reduce power consumption, thus achieving the effect of energy saving.

[0051] (4) By setting a slot on the cover plate and a buckle on the guide rod, the guide rod can be engaged with the slot on the cover plate by the buckle after assembly, so that the cover plate, the guide rod and the housing are relatively fixed. This integrates the function of the guide rod and further simplifies the overall structure of the LED light.

[0052] (5) By setting a second conductive electrode at the end of the guide rod and a third conductive electrode on the power board, electrical connection can be achieved by the contact of the two conductive electrodes; by setting a conductive plug, the gap between the second conductive electrode and the third conductive electrode can be compensated, which has a tightening effect and helps to improve the stability of the electrical connection; at the same time, the conductive plug is connected to the cover plate, which can achieve radial limiting of the cover plate to improve the assembly stability of the guide rod.

[0053] (6) The third conductive electrode is provided with a first conductive sheet, a second conductive sheet and a base plate, which are connected to each other and connected to the power board through the first conductive sheet and the base plate. The overall structure is stable by engaging the wire groove of the housing. After the limit ring is set to engage the third conductive electrode through the limit hole, the overall strength is further improved, so that it can support the digital display controller, which improves the convenience of assembly and the stability of application.

[0068] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0069] like Figures 1-12 As shown, the LED lamp of the present invention includes a housing 1, a lamp assembly 2, a power board 3, a guide rod 4, a cover plate 5, a second conductive electrode 6, a third conductive electrode 7, a conductive insert plate 8, a digital display controller 9, and a limiting ring 10.

[0070] like Figures 1-5 As shown, the housing 1 has a lamp slot 101 and a plate slot 102, and multiple lamp slots 101 are arranged around the plate slot 102; the lamp group 2 is arranged in the lamp slot 101; and the power board 3 is arranged in the plate slot 102.

[0071] As described above, in this LED lamp structure, several lamp groups 2 are used as lighting components. In this way, if a single lamp group 2 is damaged, it can be replaced individually, which reduces the application cost.

[0072] Among them, multiple lamp slots 101 for installing lamp group 2 are arranged around the slot 102 for installing power board 3, which makes it convenient to electrically connect lamp group 2 and power board, and has the advantage of reasonable layout.

[0073] Specifically, in a single lamp group 2, the lighting part uses a short light strip with multiple LED beads.

[0074] like Figure 3 , Figure 4 , Figure 6 and Figure 12 As shown, the guide rod 4 is conductive, the housing 1 of the guide rod 4 is inserted into and engages with the lamp group 2, and the guide rod 4 is electrically connected to the lamp group 2 and the power board 3.

[0075] As described above, the guide rod 4 acts as a limiting component. After being assembled into the housing 1, it will engage with the lamp group 2 to achieve the positioning of the lamp group 2. Thus, when a single lamp group 2 is damaged, or when a part of the lamp beads inside a single lamp group 2 is damaged, the guide rod 4 can be removed to disassemble and replace the lamp group 2 without having to replace the entire lamp group 2, which can reduce costs and reduce resource waste.

[0076] Meanwhile, the guide rod 4, as a conductive component, is electrically connected to the lamp group 2 and the power board 3, so that the power board 3 can supply power to the lamp group 2 and facilitate the power board 3 to distribute power to the surrounding lamp groups 2; this realizes the functional integration of the guide rod 4 and simplifies the structure of the LED lamp.

[0077] like Figure 3 , Figure 5 and Figure 12 As shown, the housing 1 has an insertion hole 103 and a through groove 104. The insertion hole 103 corresponds to the middle position of two adjacent lamp slots 101. The through groove 104 is connected to the lamp slot 101 and the insertion hole 103. The lamp group 2 has a positioning groove 201. The guide rod 4 is partially exposed through the through groove 104 and engages with the positioning groove 201.

[0078] As described above, the insertion hole 103 is used to insert the guide rod 4. At this time, both sides of the guide rod 4 will be exposed through the through groove 104, thereby fitting the positioning groove 201 of the lamp assembly 2. This prevents the lamp assembly 2 from coming out of the lamp groove 101 and realizes the assembly and fixation of the lamp assembly 2.

[0079] When it is necessary to replace the lamp assembly 2, pull out the guide rod 4 to release the locking limit of the lamp assembly 2, so that the lamp assembly 2 has the advantages of convenient disassembly and assembly and easy maintenance.

[0080] like Figure 3 As shown, the lamp assembly 2 includes a lamp housing 21, a lamp strip 22, an electrode plate 23, and a first conductive electrode 24. The lamp housing 21 is disposed in the lamp slot 101 and has a positioning groove 201. The lamp strip 22 is disposed in the lamp housing 21. The electrode plate 23 is disposed in the lamp housing 21 and is electrically connected to the lamp strip 22. The first conductive electrode 24 is electrically connected to the electrode plate 23 and penetrates through the lamp housing 21 and is electrically connected to the guide rod 4.

[0081] As described above, the lamp housing 21 is used to accommodate the lamp strip 22. Each end of the lamp strip 22 is electrically connected to an electrode plate 23. A first conductive electrode 24 is provided on the electrode plate 23, and the first conductive electrode 24 passes through the lamp housing 21, with the passing position corresponding to the positioning groove 201. Thus, after the guide rod 4 is inserted, the guide rod 4 can contact the first conductive electrode 24 to achieve electrical connection.

[0082] Specifically, the end of the guide rod 4 is tapered, and the first conductive electrode 24 is an elastic sheet to avoid interference with the first conductive electrode 24 during the insertion of the guide rod 4, which could cause damage.

[0083] In this structure, the lamp assembly 2 includes a lamp housing 21, a lamp strip 22, an electrode plate 23, and a first conductive electrode 24. Taking four lamp assemblies 2 as an example, the length of the lamp strip 22 in each lamp assembly 2 is 1 / 4 meter, and the cost is a dozen yuan. Even if the lamp housing 21, the electrode plate 23, and the first conductive electrode 24 are replaced together, it is still far lower than the cost of replacing the entire lamp strip.

[0084] The lamp housing 21 is insulated with plastic, while the substrate 23 and the first conductive electrode 24 can be made of conductive metal.

[0085] Specifically, there are four lamp groups 2 and four guide rods 4. Each lamp group 2 is electrically connected to two adjacent guide rods 4, so that two guide rods 4 are used as positive terminals and the other two guide rods 4 are used as negative terminals.

[0086] like Figure 3 As shown, the guide rod 4 includes an inner cylinder 41, an end cylinder 42, and an outer cylinder 43. One end of the inner cylinder 41 is sealed and the inner cylinder 41 is made of metal. The end cylinder 42 is made of insulating material and is connected to the open end of the inner cylinder 41. The outer cylinder 43 is sleeved on the inner cylinder 41, and the outer cylinder 43 is conductive and is electrically connected to the lamp assembly 2 and the power board 3.

[0087] As described above, the inner cylinder 41 is connected to the end cylinder 42. The sealing end of the inner cylinder 41 is fitted with the outer cylinder 43. The inner cylinder 41 is made of corrosion-resistant and water-resistant metal and fits the outer cylinder 43. The outer cylinder 43 is made of metal with excellent conductivity. The end cylinder 42 is made of insulating material.

[0088] After assembly, the outer cylinder 43 contacts the power board 3 and the first conductive electrode 24, realizing the electrical connection between the power board 3 and the lamp group 2.

[0089] The end cylinder 42 is an open structure and is connected to the inner cylinder 41. In this way, the airflow can enter the guide rod 4 through the end cylinder 42 to dissipate heat from the inner cylinder 41 and the outer cylinder 43, so as to ensure the current carrying capacity of the outer cylinder 43, which is conducive to ensuring the stable operation of the LED lamp and can reduce power consumption, thus achieving the effect of energy saving.

[0090] Especially when used in freezers and refrigerators, the guide rod 4, as a flow-through component, has excellent heat dissipation effect and can significantly reduce the energy consumption of LED lights;

[0091] This structure is made of corrosion-resistant and water-resistant metal, which avoids rust problems and ensures efficient heat conduction.

[0092] like Figure 3 , Figure 8 and Figure 9As shown, the guide rod 4 also includes a buckle 44, wherein the cover plate 5 is fastened to the housing 1, and the cover plate 5 is provided with a slot 501; the buckle 44 is connected to the end cylinder 42 and engages with the slot 501.

[0093] As described above, the cover plate 5 is used to close the housing 1. After the cover plate 5 is fastened to the housing 1, the guide rod 4 is assembled. As the guide rod 4 is inserted into the housing 1, its buckle 44 will engage in the slot 501 of the cover plate 5. In this way, the guide rod 4, the housing 1 and the cover plate 5 are relatively limited.

[0094] When it is necessary to disassemble and maintain the lamp assembly 2, move the clip 44 to disengage it from the slot 501 of the cover plate 5, then pull out the guide rod 4 and remove the cover plate 5 for maintenance.

[0095] Meanwhile, since the guide rod 4 connects the lamp group 2 and the power board 3 to form an electrical connection, when the lamp group 2 needs to be replaced, pulling out the guide rod 4 will simultaneously disconnect the electrical connection, thus improving the safety of disassembly and assembly.

[0096] like Figures 7-10 As shown, the second conductive electrode 6 is electrically connected to the end of the outer cylinder 43; the third conductive electrode 7 is electrically connected to the power board 3; the conductive insert plate 8 is connected to the cover plate 5, the conductive insert plate 8 is inserted into the shell 1, and abuts against the second conductive electrode 6 and the third conductive electrode 7.

[0097] As described above, the second conductive electrode 6 is electrically connected to the outer cylinder 43 of the guide rod 4, and when it comes into contact with the third conductive electrode 7, the lamp group 2 and the power board 3 are electrically connected.

[0098] Furthermore, after the cover plate 5 is installed, the conductive insert plate 8 will be inserted into the housing 1 and positioned between the second conductive electrode 6 and the third conductive electrode 7. This can compensate for the gap between the second conductive electrode 6 and the third conductive electrode 7, achieving a tightening effect, which is beneficial to improving the stability of the electrical connection.

[0099] Meanwhile, the conductive insert 8 is connected to the cover plate 5, which enables radial limiting of the cover plate 5 to improve the assembly stability of the guide rod 4.

[0100] like Figure 7 and Figure 10 As shown, the third conductive electrode 7 includes a first conductive sheet 71, a second conductive sheet 72, and a substrate 73. The first conductive sheet 71 is electrically connected to the power board 3. One end of the second conductive sheet 72 is electrically connected to the first conductive sheet 71, and the second conductive sheet 72 has an arc-shaped structure and abuts against the conductive insert 8.

[0101] As described above, the first conductive sheet 71 and the second conductive sheet 72 are used for current transmission between the power board 3 and the guide rod 4.

[0102] The second conductive sheet 72 has an arc-shaped structure, which provides a certain degree of elasticity. After the conductive insert 8 is inserted, it can improve the holding force and ensure stable current transmission.

[0103] Specifically, the second conductive sheet 72 of both the second conductive electrode 6 and the third conductive electrode 7 are configured as arc-shaped elastic sheets so that they can stably support the conductive insert 8.

[0104] Furthermore, the bottom sheet 73 is connected to the other end of the second conductive sheet 72, and the bottom sheet 73 is connected to the power board 3; the housing 1 has a wire groove 105 that connects the lamp groove 101 and the plate groove 102, and the two ends of the second conductive sheet 72 are engaged in the wire groove 105.

[0105] As described above, by setting a substrate 73, which is connected to the second conductive sheet 72 and to the bottom surface of the power board 3, the connection strength between the third conductive electrode 7 and the power board 3 can be improved.

[0106] Meanwhile, the third conductive electrode 7 also engages with the wire groove 105 on the housing 1, which can limit the position of the third conductive electrode 7. After the power board 3 is fixed to the housing 1 by screws, the whole structure has very good structural stability, which can ensure reliable application.

[0107] like Figure 7 and Figure 11 As shown, the digital display controller 9 is fitted into the opening of the slot 102 and passes through the cover plate 5; the digital display controller 9 is electrically connected to the power board 3, and the digital display controller 9 abuts against the third conductive electrode 7.

[0108] As described above, the digital display controller 9 is used for information display, such as connecting to a temperature sensor or humidity sensor to detect the application environment; the digital display controller 9 is electrically connected to the power board 3 for power supply.

[0109] During installation, the digital display controller 9 is fitted into the slot 102, with its bottom abutting against the third conductive electrode 7.

[0110] When the cover plate 5 is installed, the digital display controller 9 has a hole in the center to correspond to the digital display controller 9 and to radially limit the digital display controller 9.

[0111] In some embodiments, the central hole of the cover plate 5 has a diameter smaller than that of the digital display controller 9. During assembly, the digital display controller 9 can be pressed down to cooperate with the third conductive electrode 7 to achieve the positioning of the digital display controller 9.

[0112] like Figure 6 and Figure 7 As shown, the limiting ring 10 is connected to the power board 3, the outer ring surface of the limiting ring 10 abuts against the inner wall of the plate groove 102, and the limiting ring 10 engages with the third conductive electrode 7 through the limiting hole 1001.

[0113] As described above, the limiting ring 10 is used to improve the structural strength of the third conductive electrode 7. The limiting ring 10 is set on the power board 3, and a limiting hole 1001 is provided around it. The inner wall of the limiting hole 1001 abuts against the first conductive piece 71 of the third conductive electrode 7, thereby positioning the first conductive piece 71, thereby improving the shock resistance, avoiding the problem of loosening, and also providing stable support for the digital display controller 9.

[0114] The assembly method of the LED lamp of the present invention includes the following steps:

[0115] S1. Solder the third conductive electrode 7 onto the power board 3;

[0116] S2. Place the power board 3 in the slot 102 of the housing 1, and set a limiting ring 10 on the power board 3;

[0117] S3. Place the lamp assembly 2 into the lamp trough 101;

[0118] S4. Integrate the conductive plug plate 8 and the digital display controller 9 onto the cover plate 5, fasten the cover plate 5 onto the housing 1, the digital display controller 9 abuts against the third conductive electrode 7, the conductive plug plate 8 is inserted into the housing 1 and abuts against the third conductive electrode 7.

[0119] S5. Weld the second conductive electrode 6 to the end of the guide rod 4;

[0120] S6. Insert the guide rod 4 into the socket 103 of the housing 1. The guide rod 4 engages with the positioning groove 201 of the lamp group 2 to position the lamp group 2, and engages with the slot 501 to position the cover plate 5. At the same time, the second conductive electrode 6 abuts against the conductive plug plate 8 to realize the power supply board 3 to supply power to the lamp group 2.

[0121] The LED light of this invention is used in refrigerators, freezers, wine cabinets, or display cases.

[0122] Specifically, this LED light structure is not only suitable for LED light strips as the lighting component, but can also use COB light strips and other components as the lighting component.
