Description

Technical Field

[0001] This utility model relates to the field of LED lamp covers, and in particular to a cylindrical LED lamp heat dissipation lamp cover. Background Technology

[0002] The lampshade, a key component of LED lighting fixtures, functions primarily to regulate light distribution, achieving soft and even light diffusion to avoid visual discomfort caused by direct sunlight and enhance the functionality and visual comfort of the lighting fixture. Lampshades are available in a variety of materials, including polycarbonate (PC), glass, plastic, and paper, each with its unique performance advantages and limitations. For example, while glass offers excellent light transmission, it is relatively fragile; PC, on the other hand, excels in high light transmittance and good impact resistance. Based on application, LED lampshades can be broadly categorized into general lighting lampshades and plant growth lampshades. The market offers a variety of LED lampshade designs, including spherical, round, and mushroom shapes, to suit different usage scenarios and decorative styles.

[0003] In practical applications, cylindrical LED lamp covers, characterized by their cylindrical structure, typically lack dedicated heat dissipation devices and rely on natural heat dissipation mechanisms. However, this mechanism is relatively inefficient. When the LED light has high power, it generates a significant amount of heat. Due to the lack of an effective heat dissipation mechanism, this heat is difficult to dissipate in a timely manner, resulting in poor heat dissipation. This situation not only affects the normal operation of the LED light but may also shorten its lifespan and even pose safety hazards. Utility Model Content

[0004] The main objective of this invention is to provide a cylindrical LED lamp heat dissipation cover, which can effectively solve the problems mentioned in the background art.

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

[0006] A cylindrical LED lamp heat dissipation lamp cover includes a lamp cover shell and an LED lamp placement area. The LED lamp placement area is provided inside the lamp cover shell for inserting LED lamps.

[0007] The outer wall of the lampshade housing has an arc-shaped notch in the middle section, and the inner wall of the arc-shaped notch has multiple heat dissipation fins. The heat dissipation fins are used to dissipate heat from the lampshade housing and the LED lamp inside. The bottom of the LED lamp placement area has a threaded part, and the threaded part is connected to a bottom connecting ring through a threaded sleeve. The bottom connecting ring is used to install the LED lamp.

[0008] The inner wall of the LED lamp placement area is connected to a reflector, and the middle section of the reflector is provided with an arc-shaped part. The arc-shaped part and the lamp cover shell form a storage cavity, and a heat conduction pipe is installed in the storage cavity. The side wall of the heat conduction pipe is provided with multiple heat conduction protrusions. These heat conduction protrusions pass through the lamp cover shell and contact the heat dissipation fins, thereby realizing heat conduction and heat dissipation.

[0009] In a further preferred embodiment, the heat dissipation fins are inserted into the inner wall of the lampshade housing and fixed to the lampshade housing by heat fusion. Multiple heat dissipation fins are distributed in a ring in the arc-shaped notch, and the heat dissipation fins are designed in a long strip shape.

[0010] In a further preferred embodiment, the threaded sleeve and the bottom connecting ring are designed as an integral unit, and the side view of the threaded sleeve and the bottom connecting ring is an inverted "T" shape. The threaded sleeve is adapted to the threaded part, and the threaded sleeve, the bottom connecting ring and the lampshade housing are made of the same material.

[0011] In a further preferred embodiment, the reflector and the arc-shaped part are designed as a single unit, and the cross-sections of both the arc-shaped part and the reflector are "C"-shaped. The protruding direction of the arc-shaped part is opposite to the protruding direction of the reflector. The inner walls of the reflector and the arc-shaped part are both reflective surfaces, and the reflection of LED light is achieved through the reflective surfaces.

[0012] In a further preferred embodiment, the heat pipe and multiple heat-conducting protrusions are designed as a single unit, with the multiple heat-conducting protrusions being equidistantly distributed on the heat pipe, and thermal grease being applied at the connection between the heat-conducting protrusions and the heat dissipation fins.

[0013] In a further preferred embodiment, the reflector is connected to the lampshade housing by an adhesive, the heat pipe is fixed to the reflector by an adhesive, and the heat pipe extends into the LED lamp holder through the bottom connecting ring.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The heat dissipation fins significantly improve the heat dissipation capacity of the lamp housing. The heat dissipation fins within the arc-shaped notch effectively dissipate the heat generated during LED operation, reducing the LED's operating temperature and thus extending its lifespan.

[0016] The integrated design of the reflector and the curved section not only enhances the structural stability of the lampshade but also improves the lighting effect. The inner wall of the reflector, acting as a reflective surface, effectively reflects the LED light, resulting in more uniform and brighter illumination.

[0017] The integrated design of the heat pipe and multiple heat-conducting protrusions enables highly efficient heat conduction and dissipation. The heat pipe passes through the bottom connecting ring and extends directly into the LED lamp holder, making close contact with it. The heat-conducting protrusions pass through the lamp cover and make direct contact with the heat sink fins, further improving heat conduction efficiency. This design ensures that the heat generated by the LED lamp can be quickly transferred to the heat sink fins and dissipated through them. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 - Figure 5 As shown, a cylindrical LED lamp heat dissipation lampshade includes a lampshade housing 1 and an LED lamp placement area 4. The lampshade housing 1 has a specially designed LED lamp placement area 4 for accommodating and inserting LED lamps, ensuring that the LED lamps can be securely installed inside the lampshade.

[0026] An arc-shaped notch 2 is cut into the middle section of the outer wall of the lampshade housing 1. This notch design is not only aesthetically pleasing but also practical. Multiple heat dissipation fins 3 are designed and installed on the inner wall of the arc-shaped notch 2. These heat dissipation fins 3 play a significant role; they effectively dissipate the heat generated by the lampshade housing 1 and the internal LED lights, thereby maintaining the normal operating temperature of the LED lights and extending their lifespan.

[0027] To further ensure stable installation of the LED lights, a threaded section 5 is designed on the inner bottom of the LED light placement area 4. The threaded section 5 is connected to the bottom connecting ring 7 via a threaded sleeve 6. This design makes the installation of the LED lights more convenient and secure. The bottom connecting ring 7 fits tightly with the LED light installation, ensuring the stability and safety of the LED lights.

[0028] In addition, a reflector 8 is connected to the inner wall of the LED lamp placement area 4. The middle section of the reflector 8 is designed with an arc-shaped part 9, which together with the lamp cover shell 1 forms a storage cavity 12. The storage cavity 12 is not only aesthetically pleasing, but also houses a heat conduction pipe 10. The side wall of the heat conduction pipe 10 has multiple heat conduction protrusions 11, which pass through the lamp cover shell 1 and directly contact the heat dissipation fins 3, thereby achieving efficient heat conduction and dissipation.

[0029] The heat dissipation fins 3 are inserted into the inner wall of the lampshade housing 1 by heat fusion and are firmly fixed to the lampshade housing 1. These heat dissipation fins 3 are designed in the shape of long strips and are distributed in a ring in the arc-shaped notch 2, which further enhances the heat dissipation effect.

[0030] The threaded sleeve 6 and the bottom connecting ring 7 are integrated into a single unit, with an inverted "T" shape on the side view, making the overall structure more compact and aesthetically pleasing. The threaded sleeve 6 perfectly matches the threaded part 5, ensuring convenient and stable installation. The threaded sleeve 6, the bottom connecting ring 7, and the lampshade housing 1 are all made of the same material, guaranteeing overall durability and consistency.

[0031] The reflector 8 and the curved section 9 are also integrated into a single design, both with a "C"-shaped cross-section. The protruding direction of the curved section 9 is opposite to that of the reflector 8. This design makes the inner walls of both the reflector 8 and the curved section 9 reflective surfaces, effectively reflecting LED light and improving the lighting effect.

[0032] The heat pipe 10 and multiple heat-conducting protrusions 11 are also integrated into a single design. The multiple heat-conducting protrusions 11 are equidistantly distributed on the heat pipe 10 to ensure uniform heat conduction. Thermal grease is also applied at the connection between the heat-conducting protrusions 11 and the heat sink fins 3 to further improve heat conduction efficiency.

[0033] To ensure the stability and reliability of each component, the reflector 8 is connected to the lamp housing 1 via adhesive, and the heat pipe 10 is fixed to the reflector 8 via adhesive. The heat pipe 10 passes through the bottom connecting ring 7 and extends directly into the LED lamp holder, ensuring close contact between the heat pipe 10 and the LED lamp holder, thereby achieving optimal heat conduction.

[0034] Insert the heat sink fins 3 into the arc-shaped notch 2 on the inner wall of the lampshade housing 1 using a heat-fusion method, ensuring they are securely fixed. Connect the inner bottom threaded portion 5 of the LED lamp placement area 4 to the threaded sleeve 6, and then connect the threaded sleeve 6 to the bottom connecting ring 7, ensuring a tight connection. Attach the reflector 8 to the inner wall of the lampshade housing 1 using adhesive, ensuring it is secure. Fix the heat pipe 10 to the reflector 8 using adhesive, ensuring it is stable. Pass the heat pipe 10 through the bottom connecting ring 7, ensuring it extends directly into the LED lamp holder. Apply thermal grease to the connection points between the multiple heat-conducting protrusions 11 on the heat pipe 10 and the heat sink fins 3, ensuring efficient heat conduction. Ensure the heat-conducting protrusions 11 are in close contact with the heat sink fins 3. Confirm that all components are securely installed and not loose. Confirm that the heat pipe 10 is in close contact with the LED lamp holder.

[0035] Insert the LED light into the LED placement area 4 inside the lampshade housing 1. Ensure the LED light fits tightly with the threaded part 5, and tighten the threaded sleeve 6 to secure the LED light. Connect the LED light's power cord to a power outlet or power adapter. Ensure the power connection is correct. Turn on the power switch; the LED light will begin to work. The heat sink fins 3, heat pipe 10, and heat-conducting protrusions 11 work together to effectively dissipate the heat generated by the LED light. During use, monitor the LED light's temperature to ensure it remains within its normal operating range. If the temperature is too high, check if the cooling system is functioning correctly. Regularly clean the lampshade housing 1 and the heat sink fins 3 to ensure that heat dissipation is not affected by dust and dirt. Check all connecting parts for tightness and re-secure or replace them if necessary.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
