Description

Technical Field

[0001] This utility model relates to the field of LED lens technology, specifically to an LED lens and LED lens assembly with an anti-overflow adhesive structure. Background Technology

[0002] An LED lens is an optical element primarily used in LED lighting fixtures. It improves lighting efficiency by altering the direction and distribution of light. It concentrates light, reduces light scattering, and ensures that light is more focused on the target area.

[0003] Common LED lenses typically use LED chips to convert electrical energy into light energy. The lens changes the direction and distribution of light propagation. An anti-overflow groove allows excess silicone to flow into the recess without overflowing into other parts of the lens. A heat dissipation device is used to dissipate heat from the LED lens.

[0004] However, once the silicone flows into the anti-overflow groove, if the space inside the groove is completely filled, the silicone that continues to flow in will overflow from the groove, making it impossible to effectively prevent silicone overflow. At the same time, the heat dissipation device is prone to failure after long-term use, and since the heat dissipation device is installed inside the LED lens assembly, it is difficult to maintain the heat dissipation device.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides a technical solution: an LED lens with an anti-overflow adhesive structure. Please refer to [link / reference]. Figure 1 Includes: LED lens housing 1, with a lampshade 2 mounted on the light-emitting end of LED lens housing 1. Please refer to [link / reference]. Figure 2 The lampshade 2 has a concave lens 4 installed inside, and a convex lens 3 is installed on the light-emitting surface of the concave lens 4. The LED chip 5 is installed inside the LED lens housing 1.

[0030] Please see Figure 4 An anti-overflow groove 6 is provided on the connecting surface of the lampshade 2. Both the inner and outer rings of the connecting surface of the lampshade 2 are provided with sealing grooves 7. Please refer to [link / reference]. Figure 3 A sealing ring 8 is installed on the connecting surface of the LED lens housing 1 and at the corresponding position of the sealing groove 7. The surface of the sealing ring 8 is provided with a threaded groove.

[0031] Connecting the LED lens housing 1 to the lamp cover 2 allows the sealing ring 8 to be inserted into the sealing groove 7. Rotating the lamp cover 2 allows the sealing ring 8 to be screwed into the sealing groove 7, thus sealing the anti-overflow adhesive groove 6 and preventing the silicone from overflowing.

[0032] Please see Figure 1 The LED lens assembly includes the aforementioned LED lens. A heat sink 9 is mounted on the right side of the LED lens housing 1, and a mounting frame 10 is mounted on the surface of the heat sink 9. Please refer to [link / reference]. Figure 6 The fan 11 is installed inside the mounting frame 10. Please refer to [link / reference]. Figure 5 The air inlet of the mounting frame 10 is fitted with a mounting ring 12, and a filter screen 13 is mounted on the surface of the mounting ring 12. Please refer to [link / reference]. Figure 1 The surface of the LED lens housing 1 is provided with heat dissipation vents 14;

[0033] By removing the mounting frame 10 from the surface of the heat sink 9, the fan 11 can be disassembled, making it easy to replace or repair the fan 11. Removing the mounting ring 12 from the surface of the mounting frame 10 makes it easy to clean the filter screen 13, thus facilitating the maintenance of the heat sink.

[0034] Please see Figure 7 The mounting ring 12 has a mounting edge 15 on its surface. The mounting edge 15 is a ring design and is inserted into the air inlet of the mounting frame 10. The mounting ring 12 can be easily installed through the mounting edge 15.

[0035] Bolts 16 are evenly distributed on the surface of the mounting ring 12. All bolts 16 pass through the mounting ring 12 and are screwed onto the surface of the mounting frame 10. The bolts 16 are used to fix the mounting ring 12.

[0036] Please see Figure 6 The air inlet of the mounting frame 10 is equipped with a protective bracket 17. Please refer to [link / reference]. Figure 5 A threaded rod 18 is screwed between the mounting frame 10 and the heat dissipation box 9, and the protective frame 17 is used to protect the fan 11.

[0037] Both the LED lens housing 1 and the heat sink 9 are equipped with connecting plates 19, and connecting rods 20 are screwed between the connecting plates 19. The heat sink 9 can be installed on the surface of the LED lens housing 1 through the connecting rods 20.

[0038] The working process of this device is as follows: First, the LED chip 5 converts electrical energy into light energy. The lens changes the direction and distribution of light propagation to achieve the desired lighting effect. The anti-overflow glue groove 6 allows excess silicone to flow into the groove. Then, the LED lens housing 1 is connected to the lampshade 2, which drives the sealing ring 8 to be inserted into the sealing groove 7. Rotating the lampshade 2 then drives the sealing ring 8 to be screwed into the sealing groove 7, which seals the anti-overflow glue groove 6 and prevents the silicone from overflowing. Finally, the threaded rod 18 is removed, allowing the mounting frame 10 to be disassembled. Pulling the mounting frame 10 out from the surface of the heat sink 9 allows the fan 11 to be disassembled, facilitating the replacement or maintenance of the fan 11. Removing the bolt 16 allows the mounting ring 12 to be disassembled, facilitating the cleaning of the filter screen 13, thus facilitating the maintenance of the heat dissipation device.
