They can not only create unique and personalized visual effects for various spaces, but also greatly improve the convenience of use and the comfort of the environment, and are an important part of modern lighting design.

[0003] Sealing performance is crucial for the performance of LED light strips. If the sealing treatment of the light strip is improper or the sealing performance is poor, it may lead to the interior of the light strip being vulnerable to external environmental factors, such as the intrusion of moisture, dust, and even corrosive substances.

[0026] Please refer to Figures 1-4 , the present utility model provides a technical solution: a highly sealed LED neon light strip, including a housing 1, an upper baffle 5, and a wick block 7. A first installation groove 11 is opened at the upper end of the housing 1, a second installation groove 12 is opened inside the housing 1, the upper baffle 5 is installed in the first installation groove 11, multiple groups of wick blocks 7 are installed in the second installation groove 12, an air extraction valve port 6 is provided on the left side of the housing 1, the air extraction valve port 6 communicates with the second installation groove 12, a sealing ring 2 is fixed in the first installation groove 11, and the sealing ring 2 is located below the upper baffle 5;

[0027] During use, the housing 1 is the main structure of the entire LED neon light strip, providing an installation space for the internal lamp core block 7. The upper baffle 5 is installed in the first installation groove 11, and air is pumped through the air extraction valve port 6. The upper baffle 5 can be adsorbed by the negative air pressure in the second installation groove 12 and cooperate with the housing 1 to form a preliminary sealing barrier. The second installation groove 12 is used to install multiple groups of lamp core blocks 7. The second installation groove 12 is connected to the air extraction valve port 6, enabling the internal air pressure to be changed through the air extraction operation. The sealing ring 2 effectively prevents external air from entering the inside of the second installation groove 12 by closely fitting the contact surfaces of the upper baffle 5 and the housing 1.

[0028] The sealing ring 2 is made of rubber, and the upper baffle 5 is made of transparent acrylic. Under the action of negative air pressure, the rubber sealing ring 2 can further enhance the fitting degree with the upper baffle 5 and the housing 1, improving the sealing effect. The function of the upper baffle 5 is to protect the lamp core block 7 and provide visual transparency.

[0029] Reflector plates 14 are provided on the front and rear sides of the second installation groove 12. The main function of the reflector plates 14 is to reflect and concentrate light.

[0030] Multiple groups of limiting grooves 13 are provided at the lower end of the second installation groove 12. The limiting grooves 13 correspond to the lamp core blocks 7. The design of the limiting grooves 13 enables each group of lamp core blocks 7 to correspond to a fixed position.

[0031] The lamp core block 7 includes a circuit board 71. The circuit board 71 is installed inside the limiting groove 13 through a connecting screw 8. The main function of the connecting screw 8 is to firmly fix the circuit board 71 inside the limiting groove 13, preventing the circuit board 71 from loosening or falling off under external forces such as vibration and impact.

[0032] Two groups of contacts 72 are fixed on both the left and right sides of the circuit board 71. Multiple groups of lamp beads 73 are provided at the upper end of the circuit board 71. The contacts 72 are connected to the lamp beads 73 through a chip resistor 74. The contacts 72 are the interfaces between the circuit board 71 and an external power source or control circuit, responsible for transmitting electrical energy and control signals, and connecting the circuit system on the circuit board 71 to external devices in a physical contact manner. The lamp beads 73 can convert electrical energy into light energy, and the chip resistor 74 is used to protect the lamp beads 73 from being impacted by excessive current.

[0033] Mounting blocks 3 are provided on both sides of the housing 1. Mounting holes 31 are formed in the mounting blocks 3. A connecting wire 4 is provided on the right side of the housing 1. The connecting wire 4 is connected to the lamp core block 7. The mounting blocks 3 and the mounting holes 31 are used on the housing 1 to fix and install the entire light strip to an external structure.

[0034] As an embodiment of the present utility model: When maintaining or overhauling the highly sealed LED neon light strip, first release the negative air pressure in the second installation groove 12 through the air extraction valve port 6, so that the upper baffle 5 is no longer tightly adsorbed on the first installation groove 11, take out the upper baffle 5 from the first installation groove 11, and perform operations such as cleaning, replacement, or fastening as required;

[0035] Then reinstall the upper baffle 5, put the upper baffle 5 back into the first installation groove 11 again, use the air extraction valve port 6 on the housing 1 to evacuate the inside of the second installation groove 12 into negative air pressure, and tightly adsorb the upper baffle 5 installed in the first installation groove 11 on the housing 1 through the negative air pressure. At the same time, the sealing ring 2 at the lower end of the upper baffle 5 enhances the sealing effect; thus, the maintenance or overhaul of the highly sealed LED neon light strip is completed.

[0036] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0037] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
