Description

Technical Field

[0001] This utility model relates to the field of LED light source technology, specifically to a modular and replaceable LED light source assembly structure. Background Technology

[0002] Currently, outdoor LED lighting systems commonly use soldered or screw-fixed modules. In practice, a single repair requires six steps, including removing the old module, cleaning the solder pads, and resoldering, taking more than 15 minutes. Furthermore, the use of high-temperature soldering irons (350±50℃) results in a 23% damage rate to adjacent modules. Although existing technologies have developed plug-in modules to improve replacement efficiency, their spring-pin contact structure experiences peak contact resistance fluctuations of up to 22mΩ at vibration frequencies of 50-200Hz, causing a flicker failure rate of up to 1526ppm and directly shortening the lamp's lifespan by more than 40%. Therefore, we propose a modular, replaceable LED light source assembly structure. Utility Model Content

[0003] The purpose of this invention is to address the problems of long repair times and high failure rates for welded LED light source assemblies in outdoor LED lighting systems, as well as the increased flickering failure rate and short lifespan of plug-in LED light source assemblies with spring pin contact structures during vibration. This invention provides a modular, replaceable LED light source assembly structure.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A modular, replaceable LED light source structure includes a power supply base. Multiple LED strip bases are stacked and fixed on the upper end of the power supply base. Each LED strip base is a square groove with an opening on the front side, and a transparent panel is fixedly installed at the opening. A quick-connect protrusion is fixedly connected to the center of each LED strip base, and an elastic clamp is fixedly held on the front side of the quick-connect protrusion. A surface-mount LED chip is fixedly connected to the center of the front side of the elastic clamp. Pressure arm protrusions are fixedly connected to the upper and lower sides of the outer wall of the elastic clamp near the inner side. A U-shaped pressure arm is fixedly connected to the front side of the pressure arm protrusion. A clamping protrusion is fixedly connected to the inner wall of the elastic clamp near the inner side. Positioning slots are provided on both the upper and lower sides of the quick-connect protrusion near the inner side. Multiple surface-mount LED chips within the same LED strip base are connected in series and electrically connected to the power supply base.

[0006] Furthermore, each of the multiple light strip bases has a connecting rod fixedly connected to its bottom end, and both sides of the power supply base and the light strip base have mating sockets that match the connecting rods. The connecting rods are then inserted into the mating sockets and fixedly connected by bolts.

[0007] Furthermore, a power connector is fixedly connected to the bottom of the connecting rod, and power connectors are embedded in the lower sidewalls of the mating grooves of the power supply base and the lamp strip base. Two square grooves are symmetrically opened on the front side of the quick-connect protrusion, and a conductive copper strip is inserted into the square groove. A driving power supply is installed in the inner cavity of the power supply base. The power connectors on the lamp strip base are electrically connected to the conductive copper strip in the inner cavity of the lamp strip base, and the power connectors at both ends of the power supply base are electrically connected to the driving power supply.

[0008] Furthermore, the pins of the elastic clamp pass through the surface-mount LED chip, and the pins of the elastic clamp abut against the conductive copper strip after passing through the surface-mount LED chip.

[0009] Furthermore, a contact sealing ring gasket is fixedly connected to the inner front wall of the elastic clamp, and the contact sealing ring gasket is arranged around the pin of the elastic clamp.

[0010] Furthermore, the front opening edge of the light strip base is provided with a snap-fit ​​step, and a fixing ring groove is provided on the front side of the snap-fit ​​step. The transparent panel is inserted into the front snap-fit ​​step of the light strip base, and an elastic clamping frame is snap-fitted and fixed on the front side of the snap-fit ​​step. Rubber sealing gaskets are fixedly connected to the contact surfaces of the elastic clamping frame, the snap-fit ​​step of the light strip base, and the transparent panel.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model provides power through a power supply base, which is then transmitted to the surface-mount LED chips within each LED strip base. The light emitted by the surface-mount LED chips shines through a transparent panel, providing illumination. The elastic clamps hold the LED chips securely to the quick-connect protrusions, ensuring they are not easily dislodged during use. The cooperation between the clamping protrusions and the positioning slots further enhances the stability of the surface-mount LED chips. Simultaneously, the design of the pressure arm protrusions and U-shaped pressure arms allows for easy replacement of the surface-mount LED chips. Simply press the upper and lower U-shaped pressure arms, similar to using a dovetail clip, and leveraging the lever principle, the inner side of the elastic clamp opens, allowing for easy removal of the elastic clamp and surface-mount LED chips from the quick-connect protrusions. This modular replacement greatly simplifies maintenance. This design not only improves the reliability and durability of the light source assembly but also reduces maintenance costs. Furthermore, the clamping force of the elastic clamps ensures tight contact between the surface-mount LED chips and the quick-connect protrusions, effectively preventing poor contact caused by vibration.

[0013] 2. This utility model, through its connecting rod and mating socket, allows for convenient connection between the light strip base and the power supply base. The use of bolts for fixing enhances the stability and reliability of the connection. This plug-in connection method not only simplifies the installation process but also improves installation efficiency, making the replacement and maintenance of the light strip base more convenient.

[0014] 3. This utility model enhances the sealing performance between the elastic clamp and the quick-connect protrusion through the design of a contact sealing ring gasket, effectively preventing moisture, dust, and other impurities from entering the connection point and ensuring the safety and stability of the circuit connection. Simultaneously, the contact sealing ring gasket is made of a soft and elastic material, adapting to pins of different sizes, resulting in a tighter fit between the elastic clamp and the quick-connect protrusion, preventing the elastic clamp from wobbling, and further improving the stability of the connection. This design not only improves the product's waterproof and dustproof rating but also extends its service life, allowing it to maintain good working condition in various harsh environments. Furthermore, the easy replacement of the contact sealing ring gasket facilitates user maintenance and reduces maintenance costs. Attached Figure Description

Positioning slots are opened on the upper and lower sides of the quick-connect protrusion 4 near the inner side. Multiple surface-mount LED chips 6 in the same LED strip base 2 are connected in series and electrically connected to the power supply base 1.

[0021] The working principle and usage process of this utility model are as follows: When in use, the device is powered by the power supply base 1, which transmits power to the surface-mount LED chips 6 within each LED strip base 2. The light emitted by the surface-mount LED chips 6 shines through the transparent panel 3, providing illumination. The elastic clamp 5 is held and fixed to the quick-connect protrusion 4 by its own elasticity, ensuring that the surface-mount LED chips 6 are not easily dislodged during use. The cooperation between the clamping protrusion 9 and the positioning slot further enhances the stability of the surface-mount LED chips 6. Simultaneously, the design of the pressure arm protrusion 7 and the U-shaped pressure arm 8 allows for easy replacement of the surface-mount LED chips 6. Simply press the upper and lower U-shaped pressure arms 8 like using a dovetail clip; leveraging this, the inner side of the elastic clamp 5 opens, allowing easy removal of the elastic clamp 5 and the surface-mount LED chips 6 from the quick-connect protrusion 4. This modular replacement greatly simplifies maintenance. This design not only improves the reliability and durability of the light source assembly, but also reduces maintenance costs. Furthermore, the clamping force of the elastic clamp 5 ensures tight contact between the surface-mount LED chip 6 and the quick-connect protrusion 4, effectively preventing poor contact caused by vibration.

[0022] In this embodiment, preferably, each of the bottom ends of the plurality of light strip bases 2 is fixedly connected with a connecting rod 13, and both sides of the power supply base 1 and the light strip base 2 are provided with mating sockets that match the connecting rods 13. After the connecting rods 13 are inserted into the mating sockets, they are fixedly connected by bolts. Through the connecting rods 13 and the mating sockets, the light strip base 2 and the power supply base 1 can be easily connected, and the bolts are used for fixing, which enhances the stability and reliability of the connection. This plug-in connection method not only simplifies the installation steps but also improves the installation efficiency, making the replacement and maintenance of the light strip base 2 more convenient.

[0023] In this embodiment, preferably, a power connector 14 is fixedly connected to the bottom of the connecting rod 13, and power connectors 15 are embedded in the lower sidewalls of the mating grooves of the power supply base 1 and the lamp strip base 2. Two square grooves are symmetrically formed on the front side of the quick-connect ridge 4, and conductive copper strips 16 are interference-fitted into these grooves. A driving power supply 11 is installed inside the cavity of the power supply base 1. The power connectors 15 on the lamp strip base 2 are electrically connected to the conductive copper strips 16 inside the lamp strip base 2, and the power connectors 15 at both ends of the power supply base 1 are electrically connected to the driving power supply 11. Through the power connector 14 and power connectors 15, the lamp strip base 2 and the power supply base 1 can be connected simultaneously, eliminating the need for additional wiring steps and further simplifying the installation process. The conductive copper strips 16 ensure stable current transmission, and the interference fit design of the square grooves enhances the connection stability between the conductive copper strips 16 and the lamp strip base 2. The driver power supply 11 provides power to the entire LED light source assembly. Its electrical connection with the power connector 15 ensures the effective transfer of power to the LED chips on the light strip base 2, thereby enabling the light source to illuminate. This design not only improves installation efficiency but also ensures the reliability and safety of the circuit connection, making the entire LED light source assembly structure more optimized and practical.

[0024] In this embodiment, preferably, the pins of the elastic clamp 5 pass through the surface-mount LED chip 6, and after passing through the surface-mount LED chip 6, the pins of the elastic clamp 5 abut against the conductive copper strip 16. This pin design of the elastic clamp 5 ensures the electrical connection between the surface-mount LED chip 6 and the conductive copper strip 16. When the elastic clamp 5 is clamped and fixed on the quick-connect protrusion 4, its pins will naturally abut against the conductive copper strip 16, forming a stable circuit connection. This design not only simplifies the circuit connection steps but also improves the reliability and stability of the connection, avoiding light source failures caused by poor contact.

[0025] In this embodiment, preferably, a contact sealing ring gasket 12 is fixedly connected to the inner front wall of the elastic clamp 5, and the contact sealing ring gasket 12 surrounds the pins of the elastic clamp 5. The contact sealing ring gasket 12 enhances the sealing performance between the elastic clamp 5 and the quick-connect protrusion 4, effectively preventing moisture, dust, and other impurities from entering the connection, ensuring the safety and stability of the circuit connection. Simultaneously, the contact sealing ring gasket 12 is made of a soft and elastic material, adapting to pins of different sizes, allowing for a tighter fit between the elastic clamp 5 and the quick-connect protrusion 4, preventing the elastic clamp 5 from shaking, and further improving the stability of the connection. This design not only improves the product's waterproof and dustproof rating but also extends its service life, enabling it to maintain good working condition in various harsh environments. Furthermore, the easy replacement of the contact sealing ring gasket 12 facilitates user maintenance and reduces maintenance costs.

[0026] In this embodiment, preferably, the front opening edge of the light strip base 2 has a snap-fit ​​step, and a fixing ring groove is formed on the front side of the snap-fit ​​step. The transparent panel 3 is inserted into the front snap-fit ​​step of the light strip base 2, and an elastic clamping frame 10 is snap-fitted and fixed on the front side of the snap-fit ​​step. Rubber sealing gaskets are fixedly connected to the contact surfaces of the elastic clamping frame 10, the snap-fit ​​step of the light strip base 2, and the transparent panel 3. The rubber sealing gaskets effectively enhance the sealing effect between the transparent panel 3 and the light strip base 2, preventing the influence of external factors such as moisture and dust on the LED light source, thereby ensuring stable light emission and long lifespan of the light source. At the same time, the cooperative design of the snap-fit ​​step and the elastic clamping frame 10 makes the installation and removal of the transparent panel 3 simple and quick, without complicated tools or steps, greatly improving the convenience of maintenance. In addition, the softness, elasticity, and easy replacement of the rubber sealing gaskets not only improve the sealing performance but also facilitate users to adjust and replace them according to usage conditions, further reducing maintenance costs. This design makes the LED light source assembly structure of this invention more modular, easier to assemble and maintain, and improves the reliability and market competitiveness of the product.
