Description

Technical Field

[0001] This utility model belongs to the field of block light technology, specifically an LED waterproof block light. Background Technology

[0002] Block LEDs typically consist of a circuit board, a housing, and a backplate. The circuit board integrates various electronic components, including but not limited to capacitors, chips, and LED beads. A common manufacturing method for block LEDs involves placing the circuit board on a backplate and then using an injection molding machine to mold the housing around the circuit board. This method is inefficient; for example, a single injection molding machine can only produce around 2000 pieces per day. Furthermore, the injection molding machine applies significant pressure during operation, which can lead to component pin deformation, loose solder joints, or even damage to the components themselves.

[0003] In addition, considering that capacitors generate heat during operation, heat dissipation grooves are usually installed at the corresponding positions on the circuit board where the capacitors are located, to meet the capacitor's heat dissipation needs. The capacitors are then sealed and protected using potting compound. Other electronic components on the circuit board rely solely on the casing and backplate for sealing and protection. In practical applications, especially outdoors or in high-humidity environments, over time, rainwater and other moisture can easily seep in through the gaps between the backplate and casing, potentially causing short circuits and corrosion of electronic components, thus affecting the normal operation of the circuit board. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides an LED waterproof block light to at least partially solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: A waterproof LED block light proposed in this utility model includes:

[0006] The circuit board has multiple sets of hot melt connection holes.

[0007] The outer shell is integrally formed by a mold, and its back is provided with multiple sets of hot melt pillars. The multiple sets of hot melt pillars are inserted into the hot melt connection holes one by one. The hot melt pillars are deformed by the hot melt machine to press and assemble the outer shell and the circuit board.

[0008] Furthermore, the outer shell is integrally formed into multiple sets by a mold, and a connecting groove is provided on the side wall of the outer shell. The connecting grooves of two adjacent sets of the outer shell are connected by a connecting column.

[0009] Furthermore, the circuit board is equipped with electronic components, and LED beads are installed at the four corners. The LED beads and electronic components are electrically connected to the circuits on the circuit board. The outer casing is equipped with LED light slots and heat dissipation slots. The LED beads correspond to the LED light slots, and the electronic components correspond to the heat dissipation slots.

[0010] Furthermore, the circuit board is also equipped with connecting wires, and the welding of the connecting wires is a prior art technique.

[0011] Furthermore, the outer casing is provided with at least two sets of heat dissipation slots, and the two or more sets of heat dissipation slots correspond to the electronic components on the circuit board. The heat dissipation slots and the LED light slots are filled with sealant to form a potting body.

[0012] The beneficial effects of this utility model by adopting the above structure are as follows:

[0013] The integrated molding of the outer shell and circuit board allows for rapid assembly, and the hot-press connection of the outer shell and circuit board is achieved through hot-melt column heating. Compared with injection molding, this method is more efficient and solves the problem of circuit board damage caused by excessive injection pressure. At the same time, the encapsulation of all electronic components on the circuit board with potting compound improves the overall waterproof performance of the block lamp.

[0014] The integrated molding process for multiple ventilated housings allows for the simultaneous hot-pressing assembly and connection of multiple housings and circuit boards, further improving the production efficiency of the block lights. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0028] See Figures 1-6 This embodiment provides an LED waterproof block light, comprising:

[0029] Circuit board 1, on which multiple sets of hot melt connection holes 2 are provided;

[0030] The outer shell 3 is integrally formed by a mold, and its back is provided with multiple sets of hot melt pillars 4. The multiple sets of hot melt pillars 4 are inserted into the hot melt connection holes 2 one by one. The hot melt pillars 4 are deformed by the hot melt machine to press and assemble the outer shell 3 and the circuit board 1.

[0031] In practice, this embodiment uses a mold to integrally form the outer shell 3 and hot-press the outer shell 3 and the circuit board 1 together. Compared with injection molding, this method is more efficient and solves the problem that excessive injection pressure may damage the circuit board 1.

[0032] It is understood that in this embodiment, the hot-melt column 4 is made of thermoplastic plastic, and the hot-melt column 4 is hot-pressed and melted by a hot-melt machine to assemble the outer casing 3 and the circuit board 1. Mounting holes 12 are correspondingly provided on the circuit board 1 and the outer casing 3.

[0033] Specifically, see Figures 7-9 In this embodiment, multiple sets of outer shells 3 are integrally formed by a mold. Connecting grooves 5 are provided on the side walls of the outer shells 3. The connecting grooves 5 of two adjacent sets of outer shells 3 are connected by connecting posts 6. The connection between multiple sets of outer shells 3 is achieved by setting the connecting posts 6. In use, multiple sets of outer shells 3 can be respectively matched with multiple circuit boards 1. The hot melt posts 4 of the corresponding outer shells 3 are inserted into the hot melt connection holes 2 of the circuit board 1. The hot melt machine simultaneously presses multiple outer shells 3 with the corresponding circuit boards 1, which improves the production efficiency of the block lamp. Using this method, tens of thousands of block lamps can be produced in one day.

[0034] Specifically, see Figures 3-6 In this embodiment, the circuit board 1 is provided with electronic components 7, and LED beads 8 are installed at the four corners. The LED beads 8 and electronic components 7 are electrically connected to the circuit on the circuit board 1. The outer shell 3 is provided with LED light slots 9 and heat dissipation slots 10. The LED beads 8 correspond to the LED light slots 9, and the electronic components 7 correspond to the heat dissipation slots 10.

[0035] It should be noted that a connecting line 13 is also soldered onto the circuit board 1, and the soldering of the connecting line 13 is a prior art technique.

[0036] Specifically, see Figure 5 and Figure 6 In this embodiment, the outer shell 3 is provided with at least two sets of heat dissipation grooves 10. The two or more sets of heat dissipation grooves 10 correspond to the electronic components 7 on the circuit board 1. The heat dissipation grooves 10 and the LED lamp grooves 9 are filled with sealant to form a potting body 11. By setting two or more sets of heat dissipation grooves 10, all electronic components 7 on the circuit board 1 are filled and sealed. The potting body 11 protects the lamp beads 8 and electronic components 7, improving the overall waterproof performance of the block lamp. It can be understood that the potting body 11 is a transparent structure.

[0037] In practice, the connecting wire 13 is soldered onto the circuit board 1. The housing 3 and circuit board 1 are assembled by inserting the hot-melt post 4 into the hot-melt connection hole 2. During assembly, the LED beads 8 are positioned within the LED light slot 9, and the electronic components 7 are positioned within the heat dissipation slot 10. The hot-melt post 4 is hot-pressed using a hot-melt machine, causing it to deform under heat. The hot-melt end of the post 4 is larger than the size of the hot-melt connection hole 2, thus connecting the circuit board 1 and the housing 3. Since multiple housings 3 are formed at once, and these housings 3 are connected by connecting posts 6, multiple block lights can be produced simultaneously using this method. After hot-melt production, the multiple block lights are divided by cutting the connecting posts 6.

[0038] Through the above steps, multiple sets of housings 3 and circuit boards 1 can be assembled simultaneously, resulting in high production efficiency. Furthermore, by potting and sealing all electronic components 7 on the circuit board 1, the overall waterproof performance of the block lamp is improved.
