DETAILED DESCRIPTION

[0068] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0069] like Figures 1 to 12 As shown, the LED lamp of the present invention includes a housing 1, a lamp group 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 plug board 8, a digital display controller 9 and a limit ring 10.

[0070] like Figure 1 to Figure 5 As shown, the housing 1 is provided with a lamp trough 101 and a board trough 102, and a plurality of lamp troughs 101 are arranged around the board trough 102; the lamp group 2 is arranged in the lamp trough 101; and the power board 3 is arranged in the board trough 102;

[0071] As described above, in the LED lamp structure, a plurality of lamp groups 2 are used as lighting components, so that when a single lamp group 2 is damaged, it can be replaced individually, thereby reducing the application cost;

[0072] Among them, a plurality of lamp slots 101 for installing the lamp group 2 are arranged around the board slots 102 for installing the power board 3, so that it is convenient to electrically connect the lamp group 2 with the power board, and has the advantage of reasonable layout;

[0073] Specifically, the lighting part of a single lamp group 2 adopts a lamp strip with a plurality of lamp beads and a short length.

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

[0075] As in the above structure, the guide rod 4 is used as a limiting component. After being assembled to the housing 1, it will engage the lamp group 2 to achieve the positioning of the lamp group 2. In this way, 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 dismantle the lamp group 2 for replacement, without having to replace all the lamp groups 2, which can reduce costs and reduce resource waste;

[0076] At the same time, the guide rod 4 serves as a conductive component, which 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 it is convenient for 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 Fig.12 As shown, the housing 1 is provided with a plug hole 103 and a through slot 104, the plug hole 103 corresponds to the middle position of two adjacent lamp slots 101, and the through slot 104 is connected with the lamp slots 101 and the plug hole 103; the lamp assembly 2 is provided with a positioning slot 201, and the guide rod 4 is partially exposed through the through slot 104 and engages with the positioning slot 201;

[0078] As in the above structure, the insertion hole 103 is used to insert the guide rod 4. At this time, both sides of the guide rod 4 are exposed through the through groove 104, so as to fit the positioning groove 201 of the lamp group 2, so as to prevent the lamp group 2 from escaping from the lamp groove 101, thereby achieving the assembly and fixation of the lamp group 2;

[0079] When the lamp assembly 2 needs to be replaced, the guide rod 4 can be pulled out to release the clamping 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, a plate 23 and a first conductive electrode 24, wherein the lamp housing 21 is arranged in the lamp slot 101 and is provided with a positioning groove 201; the lamp strip 22 is arranged in the lamp housing 21; the plate 23 is arranged in the lamp housing 21 and is electrically connected to the lamp strip 22; the first conductive electrode 24 is electrically connected to the plate 23, and the first conductive electrode 24 passes through the lamp housing 21 and is electrically connected to the guide rod 4;

[0081] As in the above structure, the lamp housing 21 is used to accommodate the lamp strip 22, and the two ends of the lamp strip 22 are electrically connected to a plate 23, and a first conductive electrode 24 is provided on the plate 23, and the first conductive electrode 24 passes through the lamp housing 21, and the passing position corresponds to the positioning groove 201, so that after the guide rod 4 is inserted, the guide rod 4 can contact with the first conductive electrode 24 to achieve electrical connection;

[0082] Specifically, the end of the guide rod 4 is configured to be conical, and the first conductive electrode 24 is configured to be an elastic sheet, so as to avoid interference with the first conductive electrode 24 and cause damage during the insertion of the guide rod 4 .

[0083] In this structure, the lamp group 2 includes a lamp housing 21, a lamp strip 22, a plate 23 and a first conductive electrode 24. Calculated based on four lamp groups 2, the length of the lamp strip 22 in each lamp group 2 is 1 / 4 meter, and the cost is more than ten yuan. Even if the lamp housing 21, the plate 23 and the first conductive electrode 24 are replaced together, the cost is much lower than the cost of replacing the entire lamp strip.

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

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

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

[0087] As in the above structure, the inner tube 41 is connected to the end tube 42, wherein the sealed end of the inner tube 41 is sleeved with the outer tube 43, the inner tube 41 is made of corrosion-resistant and water-resistant metal, and fits the outer tube 43, the outer tube 43 is made of metal with good conductivity, and the end tube 42 is made of insulating material;

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

[0089] The end tube 42 is an open structure and is connected to the inner tube 41, so that the airflow can enter the guide rod 4 through the end tube 42 to achieve heat dissipation of the inner tube 41 and the outer tube 43, so as to ensure the flow capacity of the outer tube 43, which is conducive to ensuring the stable operation of the LED lamp, and can reduce power consumption and achieve energy-saving effect;

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

[0091] In this structure, since it is made of corrosion-resistant and water-resistant metal, rust problems can be avoided and heat conduction efficiency can be guaranteed.

[0092] like Figure 3 , Figure 8 and Fig. 9As shown, the guide rod 4 further includes a buckle 44, wherein the cover plate 5 is buckled on the housing 1, and a slot 501 is provided on the cover plate 5; the buckle 44 is connected to the end tube 42 and is buckled in the slot 501;

[0093] As in the above structure, the cover plate 5 is used to close the housing 1. After the cover plate 5 is buckled onto the housing 1, the guide rod 4 is assembled. As the guide rod 4 is inserted into the housing 1, its buckle 44 will be buckled into the slot 501 of the cover plate 5, so that the guide rod 4, the housing 1 and the cover plate 5 are relatively limited.

[0094] When the lamp assembly 2 needs to be disassembled for maintenance, the buckle 44 is moved to disengage it from the slot 501 of the cover plate 5, and then the guide rod 4 can be pulled out and the cover plate 5 can be removed for maintenance;

[0095] At the same time, since the guide rod 4 connects the lamp group 2 and the power board 3 to achieve electrical connection, when the lamp group 2 needs to be replaced, pulling out the guide rod 4 will simultaneously disconnect the electrical connection, thereby improving the safety of disassembly and assembly.

[0096] like Figure 7 to Figure 10 As shown, the second conductive electrode 6 is electrically connected to the end of the outer tube 43; the third conductive electrode 7 is electrically connected to the power board 3; the conductive plug 8 is connected to the cover plate 5, and the conductive plug 8 is plugged into the housing 1 and abuts against the second conductive electrode 6 and the third conductive electrode 7;

[0097] As in the above structure, the second conductive electrode 6 is electrically connected to the outer tube 43 of the guide rod 4, and when it contacts the third conductive electrode 7, the electrical connection between the lamp group 2 and the power board 3 is realized;

[0098] Furthermore, after the cover plate 5 is installed, the conductive plug plate 8 is inserted into the housing 1 and is located between the second conductive electrode 6 and the third conductive electrode 7, which can compensate for the gap between the second conductive electrode 6 and the third conductive electrode 7, and has a tightening effect, which is beneficial to improving the stability of the electrical connection;

[0099] At the same time, the conductive plug plate 8 is connected to the cover plate 5 , which can achieve radial limitation of the cover plate 5 to improve the assembly stability of the guide rod 4 .

[0100] like Figure 7 and Fig.10 As shown, the third conductive electrode 7 includes a first conductive sheet 71, a second conductive sheet 72 and a bottom sheet 73, wherein 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 is in an arc-shaped structure and abuts against the conductive plug board 8;

[0101] As in the above structure, 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 is in an arc-shaped structure, which has a certain elasticity. After the conductive plug 8 is inserted, it can improve the holding force and ensure the stable current transmission.

[0103] Specifically, the second conductive sheet 72 of the second conductive electrode 6 and the third conductive electrode 7 are both configured as arc-shaped elastic sheets, so that the two can stably resist the conductive plug 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 is provided with a wire groove 105 connecting the lamp groove 101 and the board groove 102, and the two ends of the second conductive sheet 72 are engaged in the wire groove 105;

[0105] As in the above structure, by providing a bottom sheet 73, which is connected to the second conductive sheet 72 and connected to the bottom surface of the power board 3, the strength of the connection structure between the third conductive sheet 7 and the power board 3 can be improved;

[0106] At the same time, the third conductive electrode 7 is also engaged with the wire groove 105 on the shell 1, which can limit the third conductive electrode 7. After the power board 3 is fixed to the shell 1 by screws, the whole has very good structural stability, which can ensure reliable application.

[0107] like Figure 7 and Fig.11 As shown, the digital display controller 9 is embedded in the opening of the board slot 102 and penetrates 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 in the above structure, the digital display controller 9 is used for information display, for example, it is connected to a temperature sensor or a 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 inserted into the plate groove 102, and the bottom is against the third conductive electrode 7;

[0110] When the digital display controller 9 is installed on the cover plate 5, a hole is opened in the center of the cover plate 5 to correspond to the digital display controller 9 and to limit the digital display controller 9 in radial direction;

[0111] In some embodiments, the diameter of the central hole of the cover plate 5 is smaller than the diameter of the digital display controller 9 . During assembly, the digital display controller 9 can be pressed 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 the third conductive electrode 7 through the limiting hole 1001;

[0113] As in the above structure, the limiting ring 10 is used to improve the structural strength of the third conductive electrode 7. The limiting ring 10 is arranged on the power board 3, and a limiting hole 1001 is arranged around it. The inner wall of the limiting hole 1001 abuts against the first conductive sheet 71 of the third conductive electrode 7 to achieve positioning of the first conductive sheet 71, thereby improving the shock resistance and avoiding the problem of looseness, and can also stably abut the digital display controller 9.

[0115] S1, welding the third conductive electrode 7 on the power board 3;

[0116] S2, placing the power board 3 in the board slot 102 of the housing 1, and setting a limit ring 10 on the power board 3;
