Description

Technical Field

[0001] This utility model relates to the field of COB packaged light source technology, specifically a COB packaged light source with strong heat dissipation capability. Background Technology

[0002] COB light sources use chip-to-board (CTO) technology to directly encapsulate multiple LED chips onto a metal substrate, forming a high-power-density integrated light source. Electrical connections are achieved through wire bonding or flip-chip technology, and resin is used to ensure reliability.

[0003] When existing COB packaged light sources are in use, their heat dissipation performance generally relies on natural heat dissipation, which can achieve a certain heat dissipation effect.

[0004] However, existing COB-packaged light sources rely solely on natural heat dissipation during prolonged illumination, resulting in poor heat dissipation and potential overheating in certain areas. This can lead to damage and reduced lifespan. To address these issues, a COB-packaged light source with enhanced heat dissipation capabilities is proposed. Utility Model Content

[0034] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0035] Combination Figure 1 and Figure 2 This utility model discloses a COB packaged light source with strong heat dissipation capability, including a package shell 1. The bottom of the package shell 1 is provided with heat dissipation fins 4. The package shell 1 can be equipped with necessary components to improve the performance. The heat dissipation fins 4 assist in heat dissipation. The copper package plate 21 and the heat conduction rod 22 are both made of copper to facilitate heat conduction. The left and right sides of the outer wall of the package shell 1 are connected to the connecting shell 3. The first locking block 18 and the second locking block 19 are engaged. When the COB light source substrate 17 rotates, the first locking block 18 can rotate and engage with the second locking block 19. The bottom of the rotating wheel 5 is provided with the COB light source substrate 17. A protective ring is provided on the outside of the rotating wheel 5 to avoid damage to the COB light source substrate 17. When the package cover 2 rotates, the rotating wheel 5 will rotate with it to reduce friction. The bottom of the COB light source substrate 17 is provided with a copper package plate 21, the bottom of the heat conduction rod 22 is provided with heat dissipation fins 4, and the top of the filter screen 15 is provided with a protrusion 27.

[0036] Combination Figures 5-7The inner walls of the two connecting shells 3 are equipped with fans 16. When the fans 16 work, they can accelerate the airflow of the encapsulation shell 1 for heat dissipation. Two limiting seats 7 are fixedly connected to one side of each of the two connecting shells 3. Support rods 12 are slidably connected through one side of the outer wall of each of the two adjacent limiting seats 7. The outer ring of each of the two adjacent support rods 12 is fitted with a first spring 14. When the moving block 11 slides in the slide groove 6, it can simultaneously pull the two support rods 12 to move, so that the insert block 13 moves out of the groove 9, releasing the limiting effect on the insert plate 8. One end of each of the two adjacent support rods 12 is fixedly connected to the insert block 13, and the other end of each of the two adjacent support rods 12 is fixedly connected to a first connecting rod 10. The other end is connected to a moving block 11. The inner walls of the two adjacent limiting seats 7 are slidably connected to the insert plate 8. The filter screen 15 is fixedly connected between the two insert plates 8. The filter screen 15 can filter dust. The insert block 13 releases the limiting of the insert plate 8, and it can be slid out by means of 27 for replacement. The inner ring of the encapsulation shell 1 is fixedly connected to a copper encapsulation plate 21. The four corners of the bottom of the copper encapsulation plate 21 are fixedly connected to heat conduction rods 22. The top of the encapsulation shell 1 is provided with an installation component. The top of the outer wall of the two connecting shells 3 is provided with a sliding groove 6. The inner walls of the two sliding grooves 6 are slidably connected to two moving blocks 11. The side of the insert plate 8 is provided with a groove 9. The inner wall of the groove 9 is provided with an insert block 13.

[0037] Combination Figures 2-4 The mounting components include a cover 2, which is threadedly connected to a housing 1. Two second locking blocks 19 are fixedly connected to the top of a copper encapsulation plate 21. Rotating the cover 2 allows the housing 1 to be mounted on it. Simultaneously, the rotating wheel 5 contacts the COB light source substrate 17 for auxiliary positioning. A rod 20 is slidably connected to the top of the copper encapsulation plate 21 through the wall. The top of the rod 20 is fixedly connected to the COB light source substrate 17. Two first locking blocks 18 are fixedly connected to the bottom of the COB light source substrate 17. When the COB light source substrate 17 rotates, the rod 20... The insertion of the rod 20 into the hole on the copper encapsulation plate 21 does not affect its rotation. The rod 20 can be positioned by inserting it into the hole on the copper encapsulation plate 21. The inner ring of the encapsulation cover 2 is fixedly connected to the outer shell 24. The top of the outer shell 24 is slidably connected to the second connecting rod 25. The outer ring of the second connecting rod 25 is fitted with a second spring 26. When the rotating wheel 5 contacts the COB light source substrate 17, the second connecting rod 25 will slide according to the force and adjust. The top of the outer ring of the second connecting rod 25 is fixedly connected to the pressure plate 23. The bottom of the pressure plate 23 is rotatably connected to the evenly distributed rotating wheels 5.

[0038] Working principle: In use, insert the pin 20 on the COB light source substrate 17 into the hole on the copper encapsulation plate 21 for positioning. Then rotate the COB light source substrate 17 to engage the first locking block 18 with the second locking block 19. Next, align the encapsulation cover 2 with the encapsulation shell 1 and rotate it. During alignment, the rotating wheel 5 will contact the COB light source substrate 17, and the second connecting rod 25 will slide according to the force applied, providing auxiliary limiting. When disassembly is required, simply rotate the encapsulation cover 2 to remove it, releasing the pressure plate 23 from its limiting position. Then rotate the COB light source substrate 17 again to separate the first locking block 18 from the second locking block 19, allowing for disassembly. When heat dissipation is required during use, the fan 16 is activated to accelerate airflow and dissipate internal heat. The copper encapsulation plate 21 and heat conduction rod 22 below can conduct heat, allowing heat to be dissipated from the heat dissipation fins 4, providing some assistance. At the same time, a filter screen 15 is provided to reduce the entry of dust. Pushing the moving block 11 moves the support rod 12, compressing the first spring 14 and moving the insertion block 13 out of the groove 9, releasing the limit on the insertion plate 8, allowing it to slide upwards to remove the filter screen 15 for cleaning and replacement. This can prevent dust during heat dissipation and improve the performance.
