Description

Technical Field

[0001] The present application relates to the technical field of LED light sources, and in particular to a six-sided luminous LED light source and a packaging structure thereof. Background Art

[0002] LED light strips are LED light beads assembled on flexible circuit boards, PCB hard boards or copper wires. They can be used as decorations or lighting projects. They have a broad application prospect in the decoration industry due to their long service life and low energy consumption. Among them, the length of LED light strips is not fixed during production. When they are used, due to different use environments and places, they often need to be cut to make them stick perfectly on the objects.

[0003] When the existing LED light strips are cut, the cut ports will expose the internal power circuits, and the power circuits of the LED light strips are extremely thin and difficult to insulate, which leads to great safety hazards in the subsequent use of the LED light strips. In addition, the part of the LED light strip with a power interface after cutting can be used normally, while the part of the LED light strip without a power interface cannot be connected to electricity, which can easily cause a waste of resources and has poor applicability and reliability.

[0004] Therefore, there is an urgent need for an LED light strip structure to solve the defects of the above-mentioned existing LED light strips in actual use. Utility Model Content

[0005] The present application proposes a six-sided LED light source and its packaging structure, which can automatically insulate the power circuit exposed by the port of the LED light strip after it is cut, and can connect the power to the part of the LED light strip without the power interface after cutting, with the advantages of good safety and applicability. It is used to solve the problem that when the existing LED light strip is cut, the cut port will expose the internal power circuit, and the power circuit of the LED light strip is extremely thin and difficult to insulate, which leads to a greater safety hazard in the subsequent use of the LED light strip. In addition, the part of the LED light strip with the power interface after cutting can be used normally, while the part of the LED light strip without the power interface cannot be connected to the power, which easily causes a waste of resources.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical solution: a six-sided LED light source, comprising a light strip substrate, on which a plurality of light sources arranged in a linear array are packaged, a neutral line is provided at the bottom end of the light strip substrate, and a live line is provided at the top end of the light strip substrate, and a parallel circuit is formed between the light source and the neutral line and the live line, and the live lines between two adjacent groups of the light sources are welded together through a connecting component;

[0007] The light source includes a welding plate packaged on a light strip substrate, a groove is provided on the top of the welding plate and an LED chip is provided thereon, and two groups of leads are provided on the LED chip to form parallel conductive connections with a neutral line and a live line respectively. At the same time, an elastic strip is provided inside the welding plate, and one end of the live line is fixedly connected to the elastic strip and pulls the live line, and a packaging colloid is provided on the outer surface of the LED chip.

[0008] Furthermore, a bubble filled with insulating glue is provided on one side of the top of the interior of the light strip substrate, and the other end of the bubble is connected to the live wire.

[0009] Furthermore, a group of extended conductive wires wrapped in the interior of the light strip substrate are respectively provided on the outer surface of the neutral wire and the live wire and on the left side of the cutting line.

[0010] A packaging structure for a six-sided LED light source, wherein the connecting component includes an outer bracket, a lower shell having a groove structure at the top end of the inner cavity of the outer bracket is movably sleeved at the bottom, and a gear connected to an external power device is fixedly sleeved at the bottom of the outer surface of the lower shell, an upper shell having a groove structure at the bottom end and matching with the top end of the lower shell is provided at the top of the inner cavity of the outer bracket, a linkage rod having a top end extending to the top of the outer bracket is fixedly sleeved inside the upper shell, a spring is movably sleeved at the top of the outer surface of the linkage rod, and a transmission connection is formed between the top of the inner cavity of the outer bracket and the top of the upper shell through the spring, and the bottom end of the linkage rod extends to the bottom of the lower shell and is fixedly installed with a winding block.

[0011] Furthermore, a group of flat grooves are respectively provided on the two corresponding sides of the outer surface of the upper shell, and an elastic pressure plate in contact with the flat grooves is provided on the outer bracket, and in the initial state, the elastic pressure plate is located above the flat grooves:

[0012] Initially, when the lower housing rotates, the upper housing and the linkage rod thereon are forced to move upwards under the elastic force of the elastic pressure plate, without synchronous rotation between them.

[0013] When the rotation reaches the limit of 180°, the pressure exerted by the spring on the upper shell due to compression becomes greater and greater, thereby overcoming the elastic force exerted by the elastic pressure plate on the upper shell, and synchronously driving the upper shell to rotate with the lower shell;

[0014] When the lower shell synchronously drives the upper shell to rotate 180°, due to the influence of another set of flat grooves, the elastic pressure plate applies a sudden pressure to the upper shell, thereby forcing a speed difference between the lower shell and the upper shell, and under the action of its upward slope, the upper shell gradually moves downward and returns to its initial position.

[0015] Furthermore, the exterior of the winding block is configured as an elliptical structure, and a group of welding contact points are respectively provided at both ends of the long side of the elliptical structure.

[0016] Furthermore, a first conductive column is provided on one side of the top end of the lower shell, and a second conductive column is provided on the other side of the bottom end of the upper shell, and the first conductive column and the second conductive column are electrically connected with the welding contact point on the winding block, and when they are in contact, the welding contact point is triggered to energize it, and the live wire at the connection between the welding contact point is welded, and the live wire is pulled during its rotation:

[0017] Initially, when the lower housing rotates, the upper housing and the linkage rod thereon are forced to move upwards under the elastic force of the elastic pressure plate, and the welding contact is triggered to be non-conductive due to the separation of the first conductive column and the second conductive column;

[0018] When the rotation reaches the limit of 180°, the pressure exerted by the spring on the upper shell due to compression becomes greater and greater, thereby overcoming the elastic force exerted by the elastic pressure plate on the upper shell, and synchronously driving the upper shell to rotate with the lower shell. At the same time, the welding contact point is triggered due to the mutual contact and conduction between the first conductive column and the second conductive column;

[0019] When the lower shell synchronously drives the upper shell to rotate 180 degrees, due to the influence of another set of flat grooves, the elastic pressure plate applies a sudden pressure to the upper shell, thereby forcing a speed difference between the lower shell and the upper shell to stagger with each other, causing the first conductive column and the second conductive column to stagger with each other and cutting off the conductive connection with the welding contact point.

[0020] The utility model application has the following technical effects:

[0021] The present application provides a six-sided light-emitting LED light source and its packaging structure. For the setting of the LED light source, when the LED light source is cut, a pulling force is applied to the live wire on it to force the live wire to shrink to the inside of the light strip substrate, thereby avoiding safety problems caused by the exposure of the wiring terminals. At the same time, for the setting of the LED light strip connecting component, when the LED light strip is packaged, elastic potential energy can be automatically applied to the elastic strip through the rotation action of the block, and power support can be provided for the contraction of the live wire when the light strip substrate is cut. The operation is simple and easy to use, which effectively improves the safety and reliability of the LED light strip during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] like Figure 5 As shown, a six-sided LED light source includes a light strip substrate 13, on which a plurality of light sources 14 arranged in a linear array are packaged, and an insulating protective glue in contact with the light strip substrate 13 is provided on the periphery of the light source 14, a neutral line 15 is provided at the bottom end of the light strip substrate 13, and a live line 16 is provided at the top end of the light strip substrate 13, and a parallel circuit is formed between the light source 14 and the neutral line 15 and the live line 16, and then the neutral line 15 and the live line 16 are conductively connected to a power interface, and a series circuit is formed to light up the light source 14 on the light strip substrate 13, and the live lines 16 between two adjacent light sources 14 are welded together through a connecting component;

[0033] like Figure 6As shown, the light source 14 includes a welding plate 20 packaged on the light strip substrate 13, a groove is opened at the top of the welding plate 20 and an LED chip 21 is arranged thereon, and two groups of leads are arranged on the LED chip 21 to form parallel conductive connections with the neutral line 15 and the live line 16 respectively, and at the same time, an elastic strip 17 is arranged inside the welding plate 20, and one end of the live line 16 is fixedly connected to the elastic strip 17 and pulls the live line 16, and a packaging colloid 22 is arranged on the outer surface of the LED chip 21. When one end of the live line 16 is cut off as the light strip substrate 13 is cut off, under the pulling force of the elastic strip 17, the cut end of the live line 16 can be pulled into and away from the cut port of the light strip substrate 13, thereby effectively avoiding the problem of one end of the live line 16 being exposed to the outside and posing a major safety hazard.

[0034] Among them, in the LED light strip composed of light sources, the light source adopts a six-sided LED light source.

[0035] The packaging process of the light source 14 includes:

[0036] Glue dispensing: apply silver glue or insulating glue on the corresponding position of the welding plate 20;

[0037] Mounting: Use a vacuum suction cup to suck up the light source and move it to the corresponding position of the light strip substrate 13 (i.e. the glue point);

[0038] Sintering: moving the mounted light strip substrate 13 to a sintering device for heating to solidify the silver paste;

[0039] Pressure welding: The positive and negative leads on the lamp source 14 are welded to the elastic strip 17 and the neutral line 15 respectively, thereby completing the lead connection work for the lamp source 14 .

[0040] The six-sided LED light source adopts the compression molding technology. After the compression molding and packaging, the light strip substrate 13 of the six-sided LED light source adopts the LED dicing process to separate it into individual lamp beads.

[0041] The light strip substrate 13 used in the six-sided LED light source is a substrate. The substrate material is substrate material or glass material or epoxy resin material. The LED light string circuit composed of the six-sided LED light source can penetrate light at the bottom, thereby forming a comprehensive light output.

[0042] like Figure 5As shown, in the present technical solution, a bubble 18 filled with insulating glue is provided on one side of the top inner side of the lamp strip substrate 13, and the other end of the bubble 18 is connected with the live wire 16, and then when the live wire 16 is cut off, the bubble 18 can be squeezed to fill the insulating glue therein into the track accommodating the live wire 16 in the lamp strip substrate 13, and the port where the live wire 16 is cut off is sealed, thereby further improving the safety and reliability of the LED light strip during actual use, wherein the welding plate 20 adopts a BT board structure.

[0043] like Figure 5 As shown, in the present technical solution, a group of extension wires 19 wrapped in the interior of the light strip substrate 13 are respectively provided on the outer surface of the neutral wire 15 and the live wire 16 and located on the left side of the cutting line. After the LED light strip is cut, the part of the LED light strip that does not include the power interface can be connected to the power supply through the extension wires 19 to ensure its normal use and effectively avoid the problem of waste of resources.

[0044] like Figure 1 , Figure 2 As shown, a packaging structure of a six-sided LED light source is provided. The connecting component includes an outer bracket 1 fixedly mounted on a packaging machine. The bottom of the inner cavity of the outer bracket 1 is movably sleeved with a lower shell 2 with a groove structure at the top, and a gear 3 connected to an external power device is fixedly sleeved at the bottom of the outer surface of the lower shell 2, so that when the gear 3 is started, the lower shell 2 can be synchronously driven to rotate. The top of the inner cavity of the outer bracket 1 is provided with an upper shell 4 with a groove structure at the bottom end and matched with the top of the lower shell 2, and a linkage rod 7 with a top extending to the top of the outer bracket 1 is fixedly sleeved inside the upper shell 4, and a spring 9 is movably sleeved at the top of the outer surface of the linkage rod 7, and a transmission connection is formed between the top of the inner cavity of the outer bracket 1 and the top of the upper shell 4 through the spring 9, so that when the lower shell 2 rotates, the upper shell 4 can be forced to drive the linkage rod 7 to move up and down along the trajectory of the groove therebetween, and the bottom end of the linkage rod 7 extends to the bottom of the lower shell 2 and is fixedly installed with a winding block 8.

[0045] like Figure 1 , Figure 2 As shown, in the technical solution, a group of flat grooves 5 are respectively provided on the corresponding two sides of the outer surface of the upper shell 4, and an elastic pressure plate 6 in contact with the flat groove 5 is provided on the outer bracket 1, and in the initial state, the elastic pressure plate 6 is located above the flat groove 5:

[0046] Initially, when the lower housing 2 rotates, the upper housing 4 and the linkage rod 7 thereon are forced to move upwards under the elastic force of the elastic pressure plate 6, without synchronous rotation between them.

[0047] When the rotation reaches the limit of 180°, the pressure exerted by the spring 9 on the upper shell 4 due to compression becomes greater and greater, thereby overcoming the elastic force exerted by the elastic pressure plate 6 on the upper shell 4, and synchronously driving the upper shell 4 to rotate along with the lower shell 2;

[0048] When the lower shell 2 synchronously drives the upper shell 4 to rotate 180°, due to the influence of another set of flat grooves 5, the elastic pressure plate 6 applies a sudden pressure to the upper shell 4, thereby forcing a speed difference to be generated between the lower shell 2 and the upper shell 4, and under the action of the upper slope, the upper shell 4 gradually moves downward and returns to its initial position.

[0049] like Figure 3 As shown, in the present technical solution, the exterior of the winding block 8 is set as an elliptical structure, and a group of welding contacts 12 are respectively provided at both ends of the long side of the elliptical structure, and then the end of the live wire 16 is welded thereon through the welding contacts 12, and when the winding block 8 rotates, the live wire 16 is pulled to apply elastic potential energy in the elastic strip 17, and provide power support for the contraction of the live wire 16 when the light strip substrate 13 is cut.

[0050] like Figure 3 , Figure 4 As shown, in the present technical solution, a first conductive column 10 is provided on one side of the top end of the lower shell 2, and a second conductive column 11 is provided on the other side of the bottom end of the upper shell 4, and the first conductive column 10 and the second conductive column 11 form a conductive connection with the welding contact 12 on the winding block 8, and when they are in contact, the welding contact 12 is triggered to energize it, and the live wire 16 at the connection with the welding contact 12 is welded, and the live wire 16 is pulled during its rotation:

[0051] Initially, when the lower housing 2 rotates, the upper housing 4 and the linkage rod 7 thereon are forced to move upwards under the elastic force of the elastic pressure plate 6, and the welding contact 12 is triggered to be non-conductive because the first conductive column 10 and the second conductive column 11 are separated from each other;

[0052] When the rotation reaches the limit of 180°, the pressure exerted by the spring 9 on the upper shell 4 due to compression becomes larger and larger, thereby overcoming the elastic force exerted by the elastic pressure plate 6 on the upper shell 4, and synchronously driving the upper shell 4 to rotate along with the lower shell 2. At the same time, the first conductive column 10 and the second conductive column 11 are in contact with each other to conduct electricity, thereby triggering the welding contact point 12;

[0053] When the lower shell 2 synchronously drives the upper shell 4 to rotate 180°, due to the influence of the other set of flat grooves 5, the elastic pressure plate 6 applies a sudden pressure to the upper shell 4, thereby forcing a speed difference between the lower shell 2 and the upper shell 4 to stagger with each other, causing the first conductive column 10 and the second conductive column 11 to stagger with each other and cut off the conductive connection with the welding contact 12.
