Description

Technical Field

[0001] This utility model relates to the field of lamp cover and lens technology, specifically to a lamp cover and lens for an LED lamp. Background Technology

[0002] LED light components generally include LEDs, lampshades, and focusing lenses. The lampshade is usually a transparent or semi-transparent shell covering the outside of the light source, and its main function is to protect the light source. Some lampshades can also help dissipate heat. The focusing lens covers the light-emitting side of the LED and focuses the light emitted by the LED on a certain illumination range, which helps to improve the light utilization rate of the LED and reduce light energy loss.

[0003] However, most lampshades and lenses currently use a separate design. Although the lens angle can be adjusted or replaced individually, resulting in more precise optical performance, there are many components, the structure is more complex, precise alignment is required, and installation is more difficult, making it suitable for professional operation. Some lampshades and lenses are integrated. While integrated designs are easier to install, they are mostly made of plastic with low thermal conductivity. Heat is difficult to conduct outward through the lampshade and tends to accumulate near the light source, which may lead to accelerated light decay and shortened lifespan, or even safety hazards due to overheating. Furthermore, integrated designs are usually fully or semi-enclosed structures, resulting in poor convection between the light source and the outside air, making it difficult for heat to dissipate through natural ventilation, which cannot meet the usage requirements. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a lampshade lens for LED lights, which has a simple structure, is easy to install, has good heat dissipation, avoids heat accumulation, extends the lifespan of LED lights, and meets usage requirements.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A lampshade lens for an LED lamp includes a lampshade body, which has a tubular structure and is narrower at the top and wider at the bottom. The upper end is the lens, and the lower end is the mounting end. The lens and the mounting end are connected, and light guide strips are provided on both sides of the connection. The light guide strips are inclined from top to bottom toward the mounting end.

[0007] Preferably, the bottom inner side of the mounting end is provided with an upwardly extending protrusion, and the bottom outer side of the mounting end is provided with a heat dissipation groove, the position of the heat dissipation groove corresponding to the position of the protrusion.

[0008] Preferably, both the lampshade body and the light guide strip are made of PC light-transmitting material.

[0009] Preferably, the bottom of the mounting end is provided with a heat dissipation gap.

[0010] Preferably, the lens is arranged in an arc shape.

[0011] The beneficial effects of this utility model are as follows: The lampshade body has a tubular structure, which is narrower at the top and wider at the bottom. The upper end is a lens, and the lower end is a mounting end. The lens and the mounting end are connected. The design with the upper end being the lens and the lower end being the mounting end is simple in structure and easy to install. Light guide strips are provided on both sides of the connection. The light guide strips are inclined from top to bottom towards the mounting end. The outer side of the lens is provided with a heat dissipation groove, which corresponds to the position of the light guide strip. By setting the heat dissipation groove, the heat accumulation in the lampshade is reduced, the airflow is guided to flow along the surface of the light guide strip, the surface area of ​​the heat dissipation path is increased, the heat dissipation effect is improved, the service life of the LED lamp is extended, and the usage requirements are met.

[0014] To more clearly illustrate the structural features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments:

[0015] This embodiment: as follows Figure 1 As shown, an LED lamp cover lens includes a lamp cover body 10, which has a tubular structure and is narrower at the top and wider at the bottom. The upper end is a lens 11, which is arc-shaped. The arc surface can refract and converge the light emitted by the LED light source to achieve light distribution at a specific angle. The lower end is a mounting end 12.

[0016] The bottom inner side of the mounting end 12 is provided with an upwardly extending protrusion 13, and the bottom outer side of the mounting end 12 is provided with a heat dissipation groove 14. The position of the heat dissipation groove 14 corresponds to the position of the protrusion 13. The bottom of the mounting end 12 is also provided with a heat dissipation gap 15. The inner protrusion 13 extends upward to increase the contact area with air. The outer heat dissipation groove 14 corresponds to the position of the protrusion 13 to form a heat dissipation fin structure, which can quickly dissipate heat through air convection. The design of the protrusion 13 can also guide the airflow at the bottom of the mounting end 12 to flow upward. The heat dissipation gap 15 at the bottom of the mounting end 12 directly connects the inside of the lamp cover body 10 with the external environment, forming an air inlet to accelerate the intake of cold air. It forms a complete convection path with the openings on both sides of the lamp cover body 10, avoiding heat accumulation at the bottom.

[0017] The lens 11 and the mounting end 12 are integrally formed and interconnected, eliminating the seams of the traditional split structure, improving the overall strength, avoiding assembly loosening or sealing problems caused by thermal expansion and contraction, and simplifying the production process and reducing assembly costs.

[0018] Light guide strips 16 are provided on both sides of the connection between lens 11 and mounting end 12. The light guide strips 16 are inclined from top to bottom toward mounting end 12, which can guide the upward-shielded light from the light source downward, reduce light loss, and uniformly distribute the light. A heat dissipation groove 17 is provided on the outer side of lens 11. The heat dissipation groove 17 corresponds to the position of the light guide strip 16. The heat dissipation groove 17 dissipates the heat on the surface of lens 11 by increasing the surface area. At the same time, the direction of the heat dissipation groove 17 is consistent with the inclined direction of the light guide strip 16, which can guide the airflow along the surface of the light guide strip 16, further improving the heat dissipation efficiency.

[0019] Both the lampshade body 10 and the light guide strip 16 are made of PC light-transmitting material. PC light-transmitting material has strong impact resistance and can withstand the heating environment of LEDs. It is not easy to yellow or become brittle due to high temperature after long-term use.

[0020] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
