[0032] In order to make the technical problems and beneficial effects of the technical solutions of the present application more clear and explicit, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0033] Embodiment 1: Please refer to Figures 1 to 11 The present embodiment provides a simple and good heat-conducting direct insertion type LED vehicle lamp, which comprises a first lamp shell 1 and a second lamp shell 2 assembled therewith, a lower part between the two is wrapped with a heat dissipation device 3, the lower part of the heat dissipation device 3 is connected with an electrical socket 4, the electrical socket 4 is connected with a copper substrate 5 located between the first lamp shell 1 and the second lamp shell 2, the copper substrate 5 is provided with a lamp bead 6, and the side parts of the first lamp shell 1 and the second lamp shell 2 are respectively provided with a plurality of integrated heat dissipation fins 7.

[0034] In the present embodiment, the first lamp shell 1 and the second lamp shell 2 are made of high-strength aluminum alloy material or high-thermal-conductivity engineering plastic, and are assembled to form the main structure of the vehicle lamp by buckles, screws or other fasteners. The lower part in the lamp shell is provided with a heat dissipation device 3, which can be an active heat dissipation element, such as a small heat dissipation fan, for accelerating the air flow in the lamp shell and assisting heat dissipation. Of course, in some low-power applications or scenes with low heat dissipation demand, the heat dissipation device 3 can also be a passive heat dissipation structure such as a heat dissipation fin, or be omitted as needed.

[0035] The side portions of the first lamp shell 1 and the second lamp shell 2 are respectively provided with an integrated heat dissipation fin 7. Specifically, the heat dissipation fin 7 is part of the structure of the lamp shell itself, not a later additional welding or assembly, but is formed at one time by the same manufacturing process as the lamp shell, such as die casting, injection molding or machining. Since the heat dissipation fin 7 is integrally formed with the lamp shell, the complex process of additionally welding fins or copper pipes on the copper substrate is saved. This not only reduces the production steps, reduces labor and equipment costs, but also avoids quality problems such as virtual welding and welding caused by welding process, thereby reducing the failure rate in the production process. The present scheme directly dissipates heat through the lamp shell body and its integrated fin, the heat conduction path is shorter and more direct, and the heat dissipation efficiency is higher. Efficient heat dissipation helps to maintain the lamp bead 6 at an appropriate working temperature, prolongs its service life, and improves the overall reliability and stability of the vehicle lamp. Moreover, the integrated design makes the lamp shell and the heat dissipation structure become a whole, the structure is more stable, the anti-vibration performance is better, and it is also easier to realize compact design.

[0036] Further, as a preferred embodiment of the present scheme but not limited, the two side surfaces of the copper substrate 5 are respectively attached to the inner side surfaces of the first lamp shell 1 and the second lamp shell 2, and the two side ends of the copper substrate 5 along the width direction are flush with the width side of the first lamp shell 1 and the second lamp shell 2, and the top end surface of the copper substrate 5 is flush with the top end side of the first lamp shell 1 and the second lamp shell 2.

[0037] In the present embodiment, in order to ensure that the heat generated from the lamp bead 6 can be efficiently transferred to the lamp shell first lamp shell 1, second lamp shell 2 and integrated heat dissipation fin 7, the mounting method and relative position of the copper substrate 5 are precisely designed. Specifically:

[0038] The copper substrate 5 has two opposite main side surfaces, in the present embodiment, which are parallel to the plane on which the lamp bead 6 is mounted, and the two side surfaces are respectively closely attached to the inner side surfaces of the first lamp shell 1 and the second lamp shell 2. This "attachment" can be achieved by precise mold design and manufacturing tolerance control, so that the two side surfaces of the copper substrate 5 are in close contact with the inner walls of the first lamp shell 1 and the second lamp shell 2 respectively, and the air gap is minimized, so as to minimize the interface thermal resistance. In some other embodiments, a heat-conducting silicone grease or a heat-conducting gasket can also be applied between the attached surfaces to further fill the small gaps and enhance the heat conduction effect.

[0039] At the same time, in order to realize the regularity and precise alignment of the structure, the two side end edges of the copper substrate 5 along the width direction are designed to be flush with the width side edges of the overall shell formed after the combination of the first lamp shell 1 and the second lamp shell 2. This means that from the side, the end of the copper substrate 5 is on the same plane as the side wall edge of the lamp shell or forms a predetermined matching profile.

[0040] Similarly, in the height or length direction, i.e. from the end of the electrical socket 4 to the light-emitting end of the lamp, the top end face of the copper substrate 5, i.e. the end away from the electrical socket 4, is designed to be flush with the top end side edge of the overall housing formed after the combination of the first lamp shell 1 and the second lamp shell 2.

[0041] The two side faces of the copper substrate 5 are tightly attached to the inner side faces of the first lamp shell 1 and the second lamp shell 2, greatly increasing the effective heat conduction contact area and significantly reducing the interfacial thermal resistance of heat transfer from the copper substrate 5 to the first lamp shell 1 and the second lamp shell 2. After the heat is conducted from the copper substrate 5 to the first lamp shell 1 and the second lamp shell 2, it can be directly and seamlessly transferred to the integrated heat dissipation fins 7 for dissipation. This structure reduces the heat transfer interface and thermal resistance. Compared with the existing design scheme as shown in the prior art, in which the copper substrate is completely built-in inside the lamp shell, there may be assembly gaps inside the lamp shell, which may cause poor heat conduction. The heat conduction path of the present scheme is shorter and more direct, and the heat dissipation efficiency is higher. Figure 11

[0042] Further, as a preferred embodiment of the present scheme but not limited, the gap of the heat dissipation fins 7 is provided with a heat dissipation hole 11. Specifically, in the gap formed between adjacent heat dissipation fins 7, a heat dissipation hole 11 is arranged to improve the air flowability around the heat dissipation fins 7. The heat dissipation hole 11 can provide an additional channel for air flow, promote the exhaust of hot air and the import of cold air, and cooperate with the heat dissipation device 3 to improve the overall heat dissipation efficiency.

[0043] Further, as a preferred embodiment of the present scheme but not limited, the first lamp shell 1 is provided with a first lamp hole 12 corresponding to the position of the lamp bead 6 on the upper part, and the second lamp shell 2 is provided with a second lamp hole 13 corresponding to the position of the lamp bead 6 on the upper part. The positions of the two lamp holes accurately correspond to the position of the lamp bead 6 fixed on the copper substrate 5, ensuring that the light emitted by the lamp bead 6 can be irradiated out through the two lamp holes.

[0044] Further, as a preferred embodiment of the present scheme but not limited, the first lamp shell 1 includes first connecting parts 14 respectively arranged on the lower two end sides, and the second lamp shell 2 includes second connecting parts 15 respectively arranged on the lower two end sides. Corresponding assembly holes for fasteners are arranged on the first connecting parts 14 and the second connecting parts 15. Limiting protrusions 16 are arranged on the end face of the first connecting parts 14 opposite to the second connecting parts 15, and limiting grooves 17 matching the limiting protrusions 16 are arranged on the second connecting parts 15.

[0045] ​Further, as a preferred embodiment of the present application but not as a limitation, the first lamp shell 1 comprises first connecting portions 14 respectively arranged at the lower ends of the two sides thereof, the second lamp shell 2 comprises second connecting portions 15 respectively arranged at the lower ends of the two sides thereof, the first connecting portions 14 and the second connecting portions 15 are respectively provided with corresponding assembly holes for fasteners, the first connecting portions 14 are respectively provided with limiting protrusions 16 on the end faces thereof opposite to the second connecting portions 15, and the second connecting portions 15 are respectively provided with limiting grooves 17 corresponding to the limiting protrusions 16.

[0046] In the present embodiment, the first lamp shell 1 is respectively provided with first connecting portions 14 at the lower ends of the two sides thereof, and the second lamp shell 2 is respectively provided with second connecting portions 15 at the lower ends of the two sides thereof. Corresponding assembly holes are arranged on each of the first connecting portions 14 and the second connecting portions 15. The positions and numbers of the assembly holes are matched with each other, and the assembly holes can be aligned when the first lamp shell 1 and the second lamp shell 2 are butted against each other, so that fasteners such as screws or bolts can be passed through and fastened, thereby firmly connecting the two lamp shells together.

[0047] In order to ensure that the first lamp shell 1 and the second lamp shell 2 can be accurately aligned when assembled, and to avoid misalignment or shaking, the present embodiment further designs limiting structures. Specifically, one or more limiting protrusions 16 are arranged on the end faces of the first connecting portions 14 facing the second connecting portions 15. Correspondingly, limiting grooves 17 are arranged on the second connecting portions 15 and matched with the limiting protrusions 16 in shape and position. The limiting protrusions 16 and the limiting grooves 17 are cooperatively designed to guide and limit the first lamp shell 1 and the second lamp shell 2 when assembled. When the two lamp shells are close to each other, the limiting protrusions 16 will first enter the limiting grooves 17, thereby ensuring that the two lamp shells can be accurately aligned in horizontal and vertical directions, and avoiding affecting the overall structure and performance due to misalignment. In addition to ensuring accurate alignment, the limiting structure can also increase the stability of the connection to a certain extent. Even if the fasteners are not completely tightened, the limiting structure can prevent the two lamp shells from sliding or rotating relative to each other, thereby improving the reliability of the overall structure.

[0048] Further, as a preferred embodiment of the present application but not as a limitation, the first lamp shell 1 is provided with a first mounting hole 18 at the upper portion thereof, the second lamp shell 2 is provided with a second mounting hole 19 corresponding to the first mounting hole 18 at the upper portion thereof, and the copper substrate 5 is provided with a third mounting hole 20 corresponding to the second mounting hole 19, and fasteners are arranged in the first mounting hole 18, the second mounting hole 19 and the third mounting hole 20.

[0049] The copper substrate 5 can be firmly fixed between the first lamp shell 1 and the second lamp shell 2 through fasteners such as screws, bolts or other suitable connectors passing through the aligned first mounting hole 18, second mounting hole 19 and third mounting hole 20, ensuring the stability of its position, preventing loosening or displacement, thereby ensuring the normal operation of the lamp beads 6 and the accuracy of the light direction. In addition, through the fastening force of the fasteners, the copper substrate 5 can be more closely attached to the first lamp shell 1 and the second lamp shell 2, thereby improving the thermal contact between them and further improving the heat conduction efficiency.

[0050] Embodiment 2: As shown in the figure, the present embodiment provides a simple and good heat-conducting direct insertion type LED car lamp. In the present embodiment, the direct insertion type LED car lamp still comprises basic components: a first lamp shell 1, a second lamp shell 2, a heat dissipation device 3, an electrical socket 4, a copper substrate 5, lamp beads 6 mounted on the copper substrate 5, and an integrated heat dissipation fin 7 located on the side of the first lamp shell 1 and the second lamp shell 2 as one of the core structures. Figures 3 to 10

[0051] In order to ensure the basic heat transfer path, similar to embodiment 1, the two major surfaces of the copper substrate 5 in the present embodiment are also preferably closely attached to the inner sides of the first lamp shell 1 and the second lamp shell 2. At the same time, the top end surface of the copper substrate 5 is flush with the top end side edge of the combination of the first lamp shell 1 and the second lamp shell 2, to realize structural positioning and partial heat conduction.

[0052] Compared with embodiment 1, the difference of the present embodiment is that a heat pipe 8 is introduced for auxiliary heat dissipation. Specifically, at both sides of the copper substrate 5 along its width direction, a heat pipe 8 is firmly connected through welding, brazing or using high-thermal-conductivity adhesive and the like.

[0053] The heat pipe 8 is a passive heat transfer element, which can be a copper pipe in the present embodiment. The length of each heat pipe 8 is approximately adapted to the length of the side edge of the copper substrate 5 to which it is connected, so as to be able to effectively absorb heat from the edge area of the copper substrate 5.

[0054] ​After the heat pipe 8 is installed, it is arranged along the edge of the copper substrate 5, and the end side of the heat pipe itself, i.e. the exposed end surface in the width direction, is designed to be flush with the width side edge of the overall housing formed after the first lamp shell 1 and the second lamp shell 2 are combined. Compared with the scheme in Embodiment 1 that relies only on the direct contact of the copper substrate to conduct heat, the heat conduction efficiency of the heat pipe 8 is much higher than that of metal direct conduction, and can quickly and remotely transport heat from the edge of the copper substrate 5 to the side wing of the lamp shell with extremely low thermal resistance. The heat spreading and dissipation capacity in the entire heat dissipation system is greatly enhanced, so that the integrated heat dissipation fin 7 can play a more uniform and sufficient role, thereby supporting higher power LED lamp beads 6 to work, or making the lamp bead temperature lower under the same power. In addition, the introduction of the heat pipe 8 helps to quickly export the heat that may accumulate at the edge of the copper substrate 5, reduces the temperature gradient on the copper substrate and the lamp shell, makes the temperature distribution of the entire heat dissipation system more uniform, and avoids local overheating. It is beneficial to prolong the service life of the LED lamp beads 6 and ensure the light color stability.

[0055] Further, in order to enable the heat pipe 8 to be accurately and stably installed inside the lamp shell and optimize its thermal contact with the lamp shell, the internal structures of the first lamp shell 1 and the second lamp shell 2 are adapted and designed differently from Embodiment 1. The inner side of the two wing ends of the first lamp shell 1 is provided with a first half groove 9 adapted to the shape of the heat pipe 8, and the inner side of the two wing ends of the second lamp shell 2 is provided with a second half groove 10 adapted to the heat pipe 8. When the first lamp shell 1 and the second lamp shell 2 are in the assembled state, the first half groove 9 and the second half groove 10 form a semi-enclosed groove.

[0056] Specifically, on the inner side of the first lamp shell 1, near the "wing end" area of the width direction edge, i.e. the position where the heat pipe 8 needs to pass through or terminate, a first half groove 9 is opened corresponding to the position of each heat pipe 8. The shape of this first half groove 9 is adaptively designed according to the shape of the heat pipe 8 to achieve shape adaptation. Similarly, at the corresponding "wing end" position on the inner side of the second lamp shell 2, a second half groove 10 is also provided which is adapted to the shape of the heat pipe 8.

[0057] When the first lamp shell 1 and the second lamp shell 2 are assembled into a complete lamp shell body, the first half groove 9 and the second half groove 10 located on the same side and corresponding to each other are accurately matched together. After combination, a semi-closed groove which extends along the heat conduction pipe 8 and substantially covers the outer periphery of the heat conduction pipe 8 is formed in the lamp shell. The first half groove 9 and the second half groove 10 provide a customized positioning groove for the heat conduction pipe 8. The first half groove 9 and the second half groove 10 provide accurate positioning and guidance for the heat conduction pipe 8, ensuring that the heat conduction pipe 8 can accurately fall into its designed position without deviation when the first lamp shell 1 and the second lamp shell 2 are assembled. At the same time, the covering and limiting effect of the groove on the heat conduction pipe 8 enhances the fixing stability of the heat conduction pipe 8 in the lamp shell, improves the resistance to vibration and impact of the entire vehicle lamp assembly, and enhances the reliability of the product. In addition, the assembly groove increases the heat contact area, further improving the overall heat dissipation performance.

[0058] Further, the heat conduction pipe 8 for strengthening heat dissipation is in a rectangular cross-sectional shape, and the first half groove 9 and the second half groove 10 are both L-shaped grooves. The design of the rectangular heat conduction pipe 8 and the L-shaped groove simplifies the processing technology, reduces the production difficulty and cost. At the same time, the processing precision of the L-shaped groove is easy to control, which can effectively improve the assembly efficiency.

[0059] The working principle of the utility model is as follows:

[0060] The utility model discloses a simple and direct insertion type LED car lamp with good heat conductivity, which is assembled by a first lamp shell and a second lamp shell matched with each other. The key components in the interior include a copper substrate bearing LED lamp beads, an electrical socket providing electric energy and a heat dissipation system. A core innovation point shared by the two embodiments is that the heat dissipation fins are directly integrally formed on the side of the lamp shell. This design discards the complex process of additional welding or assembly of traditional heat dissipation fins, simplifies production, reduces cost and potential welding defect risk, and more importantly, shortens the path of heat transfer from the lamp shell to the heat dissipation surface, reduces thermal resistance, improves heat dissipation efficiency and overall stability of the structure.

[0061] Embodiment 1 mainly relies on the heat dissipation mechanism of direct contact and conduction. The key is that the copper substrate with high thermal conductivity is designed to tightly adhere to the inner side walls of the two lamp shells in a large area. This design ensures that the heat generated by the LED can be efficiently conducted from the copper substrate to the lamp shell body, and then rapidly dissipated to the surrounding environment through the lamp shell and its integrated heat dissipation fins. The optional internal heat dissipation device (such as a fan) and the heat dissipation holes between the fins can further assist heat dissipation.

[0062] The embodiment 2 introduces an enhanced heat dissipation mechanism on the basis of the embodiment 1. The close heat transfer path between the copper substrate and the lamp shell is retained, but an efficient heat pipe is additionally connected at the edge position of the width direction of the copper substrate. The heat dissipation efficiency is further enhanced, so that the integrated heat dissipation fins can play a more uniform and sufficient role, thereby supporting higher power of the LED to work or realizing lower operating temperature, and improving the temperature distribution uniformity.

[0063] The above is the embodiment provided in combination with the specific content, and it is not considered that the specific implementation of the present application is limited to these descriptions. Any similar structure or method as the present application, or any technical deduction or replacement made on the basis of the concept of the present application, should be considered as the protection scope of the present application.
