Description

Technical Field

[0001] This utility model relates to the field of light-emitting diode (LED) module technology, and in particular to an LED packaging module and an LED module. Background Technology

[0002] Currently, mainstream LED light strip products generally adopt a hybrid topology design of "series-connected unit light emitters + parallel connection between units." The technical logic is as follows: Multiple sets of unit light emitters are used. Each set consists of 2-12 light-emitting diodes (LED chips) connected in series via metal wires or copper foil on a flexible printed circuit board (FPC), forming an independent light-emitting unit with a specific operating voltage (e.g., 12V, 24V). All LED chips within this unit share the same current loop, ensuring consistent brightness. Multiple of these unit light emitters are then connected in parallel via a main cable or FPC main circuit, and the entire unit is connected to an external driver power supply. The core purpose of this design is to ensure that when a single unit light emitter is disconnected due to a circuit fault, it will not affect the normal power supply to other parallel units, thus guaranteeing the basic lighting function of the entire light strip. To achieve series connection of LED chips within a single-unit light emitter, existing technologies generally use a series connector as the core connection component. Its specific application scenarios and technical limitations are as follows: The series connector is typically a small, injection-molded connector with built-in metal conductive terminals. One end is soldered to the negative pin of the preceding LED chip, and the other end is connected to the positive pin of the following LED chip. Current conduction is achieved through mechanical fastening or soldering. This component must simultaneously meet the requirements of electrical conductivity, mechanical stability, and miniaturization, making it a critical node in the series circuit of the single-unit light emitter. Since the LED chips within the single-unit light emitter form a closed circuit through the series connector, if any LED chip in the circuit experiences damage such as PN junction breakdown or electrode detachment, or if the series connector itself suffers from terminal oxidation or poor contact, the current circuit of the entire single-unit light emitter will be interrupted, resulting in the entire unit going out of power. Because the unit light emitter uses a series structure, and the series connectors are mostly integrated inside the FPC or the package shell, it is difficult to quickly pinpoint whether the LED chip is damaged or the series connector is faulty when the unit fails to turn off, making it impossible for maintenance personnel to perform targeted repairs. Limited by the integrated packaging design of LED light strips (such as potting waterproof structure and flexible circuit integration), even if the faulty component is identified, it is impossible to disassemble and replace the damaged LED chip or series connector individually; the entire light strip segment containing the faulty unit light emitter must be replaced. This whole-unit replacement method results in the disposal of a large number of still-functioning LED chips, circuits, and connectors, increasing maintenance costs for users and generating a large amount of electronic waste, which is inconsistent with the green and low-carbon industrial development trend. Utility Model Content

[0003] The purpose of this utility model is to provide a light-emitting diode (LED) packaging module and LED module, which aims to solve the problem of high cost caused by inconvenient maintenance, thereby reducing the actual cost of use.

[0004] The technical solution adopted in this utility model is as follows: A light-emitting diode (LED) package module, comprising: Packaging substrate; LED light emitters are mounted on the encapsulation substrate; The first electrode sheet is disposed on the packaging substrate and is connected to the first electrical connection point of the LED light-emitting body; The second electrode is disposed on the packaging substrate and is connected to the second electrical connection point of the LED light-emitting element; The first electrode extends toward one end of the packaging substrate, and a connector is provided at the extended end of the first electrode. The second electrode extends toward the other end of the packaging substrate, and a connector slot is provided at the extended end of the second electrode. Adjacent LED packaging modules are electrically connected to each other through the connector and the connector slot.

[0005] This utility model also has the following technical features: In one embodiment of the present invention, a light-transmitting cover is further included, which is detachably connected to the encapsulation substrate and is arranged along the length direction of the encapsulation substrate.

[0006] In one embodiment of the present invention, the encapsulation substrate is generally rectangular, the connector is sheet-shaped and protrudes from one end of the encapsulation substrate, the connector slot is generally rectangular, and the encapsulation substrate is inserted into the cavity of the connector slot.

[0007] In one embodiment of this utility model, the two sides of the connector are provided with protrusions in an array, and the inner wall of the connector slot is provided with a slot corresponding to the protrusions.

[0008] In one embodiment of the present invention, the edge of the connector plug is provided with a receiving groove, and one end of the connector slot extends into the cavity of the receiving groove.

[0009] In one embodiment of the present invention, a snap-fit ​​groove is provided on one side of the packaging substrate, a heat-conducting base is provided in the snap-fit ​​groove, and the LED light emitter is disposed on the heat-conducting base.

[0010] In one embodiment of the present invention, the first electrical connection point and the second electrical connection point are generally pin-shaped, and the first electrode plate and the second electrode plate are provided with insertion holes, and the first electrical connection point and the second electrical connection point are respectively inserted into the insertion holes of the first electrode plate and the second electrode plate.

[0011] In one embodiment of the present invention, longitudinal grooves and transverse grooves are provided on the other side of the packaging substrate. The longitudinal grooves are arranged in multiple sets at intervals along the width direction of the packaging substrate, and the transverse grooves are arranged in multiple sets at intervals along the length direction of the packaging substrate.

[0012] In one embodiment of the present invention, the packaging substrate is provided with snap-fit ​​grooves on both sides, the snap-fit ​​grooves are arranged along the length direction of the packaging substrate, and the packaging light-transmitting cover is provided with snap-fit ​​flanges on both sides, the snap-fit ​​flanges extending into the snap-fit ​​grooves.

[0013] Another objective of this utility model is to provide a light-emitting diode module, which includes the aforementioned light-emitting diode packaging module, wherein multiple sets of the light-emitting diode packaging modules are connected at both ends to form a single unit.

[0014] Compared with existing technologies, the advantages of this invention are as follows: By integrating individual LED light emitters onto an independent packaging substrate, and relying on the connector plug of the first electrode plate and the connector slot of the second electrode plate to achieve detachable electrical connection between adjacent modules, when a fault occurs in the LED light emitter or electrode structure of a certain packaging module, it is not necessary to disassemble the entire light strip. Only the connector plug of the faulty module needs to be separated from the connector slot of the adjacent module to replace the faulty module individually, avoiding the waste of a large number of normal components. Since each packaging module is an independent functional unit and modular splicing is achieved through the connector plug and slot structure, when a partial failure occurs in the light strip, the faulty module can be quickly located by disconnecting the connector plugs and connector slots of adjacent modules one by one, without disassembling the packaging shell or inspecting the internal series circuit, thus improving maintenance convenience.

[0017] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0018] The illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0019] It should be noted that in practical applications of LED modules, because the unit light emitters use a series structure and the series connectors are mostly integrated inside the FPC or the package shell, when a unit fails to turn off, it is difficult to quickly determine whether the problem lies with the damaged LED chip or the series connector, making it impossible for maintenance personnel to perform targeted repairs. Limited by the integrated packaging design of LED light strips (such as potting waterproof structures and flexible circuit integration), even if the faulty component is identified, it is impossible to disassemble and replace the damaged LED chip or series connector individually; the entire light strip segment containing the faulty unit light emitter must be replaced. The traditional method of replacing entire LEDs results in the disposal of numerous still-functioning LED chips, circuits, and connectors, increasing user maintenance costs and generating significant electronic waste. This contradicts the trend of green and low-carbon industrial development. To address this, a light-emitting diode (LED) packaging module is proposed, comprising: a packaging substrate 10; an LED emitter 20 mounted on the packaging substrate 10; a first electrode 30 disposed on the packaging substrate 10 and connected to a first electrical connection point 21 of the LED emitter 20; and a second electrode 40 disposed on the packaging substrate 10 and connected to a second electrical connection point 22 of the LED emitter 20. The first electrode 30 extends towards one end of the packaging substrate 10, and its extended end is provided with a connector 31. The second electrode 40 extends towards the other end of the packaging substrate 10, and its extended end is provided with a connector slot 41. Adjacent LED packaging modules are electrically connected via the connector 31 and the connector slot 41.

[0020] In one embodiment, see Figure 1 The encapsulation substrate 10 is made of resin material. The first electrode sheet 30 and the second electrode sheet 40 extend along the length of the encapsulation substrate 10 to both ends. Adjacent LED encapsulation modules are connected as one unit by connecting plug 31 and connecting slot 41, which can be easily replaced. When there is a problem with the entire LED light strip, it is only necessary to remove the module with the bad pixel. Replacement is very convenient and quick.

[0021] In one embodiment, the first electrical connection point 21 and the second electrical connection point 22 are both conductive contacts provided on the LED light-emitting body 20. When the LED light-emitting body 20 is installed on the packaging substrate 10, the first electrical connection point 21 and the second electrical connection point 22 can make electrical contact with the first electrode plate 30 and the second electrode plate 40, thereby realizing electrical connection.

[0022] To protect the LED light emitter 20 and prevent moisture from corroding it, thereby improving the lifespan of the entire LED light emitter 20, the LED packaging module also includes a light-transmitting cover 50, which is detachably connected to the packaging substrate 10 and arranged along the length of the packaging substrate 10.

[0023] In one embodiment, the light-transmitting cover 50 is made of a light-transmitting organic composite material. When the light-transmitting cover 50 is placed on the encapsulation substrate 10, it can diffusely reflect the light emitted by the LED light emitter 20 when the LED light emitter 20 is lit, making the light transmitted through the light-transmitting cover 50 more uniform.

[0024] The aforementioned light-transmitting cover 50 is placed on the encapsulation substrate 10, which can effectively protect the LED light-emitting element 20, prevent moisture from entering the LED light-emitting element 20, and ensure the service life of the LED light-emitting element 20.

[0025] In one embodiment, see Figure 1 and Figure 2 To facilitate the connection between the connection slot 41 and the connection plug 31, and to ensure the reliability of the electrical connection between the connection slot 41 and the connection plug 31, the packaging substrate 10 is generally rectangular plate-shaped, the connection plug 31 is sheet-shaped and protrudes from one end of the packaging substrate 10, the connection slot 41 is generally rectangular box-shaped, and the packaging substrate 10 is inserted into the box cavity of the connection slot 41.

[0026] In one embodiment, to ensure the reliability of the electrical connection between the connection slot 41 and the connection plug 31, protrusions 311 are arranged in an array on both sides of the connection plug 31, and slots 411 are provided on the inner wall of the connection slot 41 corresponding to the protrusions 311.

[0027] The connecting slot 41 and the connecting plug 31 have a certain deformation capability and can conduct electricity normally. The cross-section of the protrusion 311 is semi-circular or small semi-circular. The cross-section of the slot 411 matches the outline of the protrusion 311. The outer size of the protrusion 311 should be slightly larger than the size of the slot 411. When the connecting slot 41 and the connecting plug 31 are inserted together, the protrusion 311 is locked in the slot 411, and the two form an interference fit to prevent the connecting slot 41 and the connecting plug 31 from arbitrarily dislodging.

[0028] In one embodiment, see Figure 1 and Figure 3 To protect the connection slot 41, the edge of the connection plug 31 is provided with a receiving groove 312, and one end of the connection slot 41 extends into the cavity of the receiving groove 312.

[0029] When the aforementioned connector 31 is inserted into the connector slot 41, and the connector slot 41 extends into the cavity of the receiving groove 312, the end faces of the package substrate 10 are fitted together to ensure the reliability of the connection between adjacent package substrates 10.

[0030] In one embodiment, in order to implement reliable heat dissipation for the LED light-emitting element 20, a snap-fit ​​groove 11 is provided on one side of the packaging substrate 10, a heat-conducting seat 60 is provided in the snap-fit ​​groove 11, and the LED light-emitting element 20 is disposed on the heat-conducting seat 60.

[0031] In order to implement the electrical connection between the first electrical connection point 21 and the second electrical connection point 22 and the first electrode plate 30 and the second electrode plate 40, the first electrical connection point 21 and the second electrical connection point 22 are generally pin-shaped, and the first electrode plate 30 and the second electrode plate 40 are provided with insertion holes. The first electrical connection point 21 and the second electrical connection point 22 are respectively inserted into the insertion holes of the first electrode plate 30 and the second electrode plate 40.

[0032] In one embodiment, a slot is provided on the heat-conducting base 60, and the LED light-emitting body 20 is fixed in the slot by thermally conductive adhesive. The first electrical connection point 21 and the second electrical connection point 22 are respectively inserted into the insertion holes of the first electrode plate 30 and the second electrode plate 40, thereby realizing the electrical connection between the LED light-emitting body 20 and the first electrode plate 30 and the second electrode plate 40.

[0033] Furthermore, to increase the heat dissipation area, longitudinal grooves 12 and transverse grooves 13 are provided on the other side of the packaging substrate 10. The longitudinal grooves 12 are arranged in multiple sets at intervals along the width direction of the packaging substrate 10, and the transverse grooves 13 are arranged in multiple sets at intervals along the length direction of the packaging substrate 10.

[0034] In one embodiment, in order to fix the light-transmitting cover 50 to the encapsulation substrate 10, the encapsulation substrate 10 is provided with snap-fit ​​grooves 14 on both sides, the snap-fit ​​grooves 14 are arranged along the length direction of the encapsulation substrate 10, and the light-transmitting cover 50 is provided with snap-fit ​​flanges 51 on both sides, the snap-fit ​​flanges 51 extending into the snap-fit ​​grooves 14.

The specific structure of the LED packaging module is as described in the above embodiments. Since this LED module adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
