DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of the present invention. Example

[0024] like Figure 1-7 As shown, this embodiment discloses a lamp housing, including a base 1 and an outer shell 2 for mounting a light-emitting element 3, the outer shell 2 and the housing are clamped and sealed by a connecting structure, the base 1 and the outer shell 2 are both made of heat-insulating plastic, the base 1 has a U-shaped cross-section, and a mounting frame 4 for mounting the light-emitting element 3 is arranged inside, a heat-insulating cavity 5 is formed between the mounting frame 4 and the inner wall of the base 1, a heat-conducting cover 6 is arranged in the heat-insulating cavity 5, the heat-conducting cover 6 is wrapped around one side of the light-emitting element 3 and the two ends are sealed and abutted against the base 1, the heat-conducting cover 6 is made of heat-conducting metal and a heat-insulating buffer layer 7 is formed between the inner wall of the base 1.

[0025] like Figure 3 As shown, the lamp housing includes a base 1 and a shell 2 for mounting a light-emitting element 3. The base 1 and the shell 2 are both made of heat-insulating plastic, and the cross-section of the base 1 is a U-shaped structure, and a mounting frame 4 for mounting the light-emitting element 3 is arranged inside the base 1. A heat-insulating cavity 5 is formed between the mounting frame 4 and the inner wall of the base 1, and the heat-insulating cavity 5 is used to prevent the heat of the light-emitting element 3 from being directly conducted to the outside of the base 1, thereby preventing the user from being burned when touching the lamp housing.

[0026] A heat-conducting cover 6 is provided in the heat-insulating cavity 5. The heat-conducting cover 6 is wrapped around one side of the light-emitting element 3, and its two ends are sealed and abutted against the substrate 1, so that a sealed cavity that wraps the heat-generating part of the light-emitting element 3 can be formed in the heat-insulating cavity 5. The sealed cavity can play a role of sealing and protecting the light-emitting element 3, thereby preventing dust and water vapor from the outside from affecting the service life of the light-emitting element 3. The heat-conducting cover 6 is made of heat-conducting metal, and the heat-conducting cover 6 can guide the heat to the outside, and can achieve heat dissipation of the light-emitting element 3; thereby improving the heat dissipation efficiency of the light-emitting element 3. A heat-insulating buffer layer 7 is formed between the heat-conducting cover 6 and the inner wall of the substrate 1. The heat-insulating buffer layer 7 contains air, which can slow down the conduction of heat, thereby further improving the heat insulation performance of the shell.

[0027] The heat-conducting cover 6 includes connecting plates 61 fixed on both sides of the mounting frame 4. A plurality of hollow heat dissipation tubes 62 are arranged between a pair of connecting plates 61. The plurality of heat dissipation tubes 62 are interconnected to form a cover body 63 with a U-shaped cross-section. Both ends of the heat dissipation tubes 62 are open to the outside.

[0028] like Figure 4 As shown, the heat-conducting cover 6 specifically includes connecting plates 61 fixed on both sides of the mounting frame 4, and a plurality of hollow heat-dissipating pipes 62 are arranged between the connecting plates 61. The heat-dissipating pipes 62 are connected to each other by welding to form a cover body 63 structure with a U-shaped cross-section, which is used to be close to the light-emitting element 3 to facilitate the heat conduction of the light-emitting element 3. The openings at both ends of the heat-dissipating pipe 62 are directly exposed to the outside, so that the outside air can flow in the heat-dissipating pipe 62, thereby accelerating the heat exchange to improve the heat dissipation efficiency.

[0029] like Figure 7 As shown, a plurality of heat dissipation holes 621 of the vertical light-emitting elements 3 are also arranged on the surrounding side of the heat dissipation pipe 62, and one-way seals 622 are installed on these heat dissipation holes 621. The function of the seal is to make the hot air in the heat-conducting cover 6 flow only toward the heat dissipation pipe 62, thereby preventing external dust and impurities from entering the insulation cavity 5, thereby enhancing the sealing effect; at the same time, the heat dissipation holes 621 of the vertical heat dissipation pipe 62 can accelerate the air flow rate at the heat dissipation holes 621 when the air in the heat dissipation pipe 62 flows, thereby accelerating the hot air in the heat-conducting cover 6 to flow into the heat dissipation pipe 62 and be discharged outward, further improving the heat dissipation efficiency.

[0030] A plurality of venturi tubes 8 corresponding to the positions of the heat dissipation holes 621 are arranged in the heat dissipation pipe 62. The inner diameters of both ends of the venturi tube 8 are the same as the inner diameter of the heat dissipation pipe 62 and gradually decrease toward the middle of the venturi tube 8. The heat dissipation holes 621 are connected to the middle position of the venturi tube 8.

[0031] The inner diameters of the two ends of the venturi tube 8 are the same as the inner diameter of the heat pipe 62, while the middle part gradually decreases, forming an acceleration effect on the circulating air. The middle part of the venturi tube 8 is connected to the heat dissipation hole 621, and the flow rate of the airflow in the heat pipe 62 can be increased by the venturi effect, thereby improving the heat dissipation efficiency.

[0032] like Figure 5 As shown, both ends of the base 1 are open and are clamped with sealing heads 9. The sealing heads 9 are provided with mounting holes 10 that are plugged with the ends of the heat dissipation pipes 62. A breathable membrane 11 is provided at the mounting holes 10.

[0033] The sealing head 9 is designed with a mounting hole 10 which is plugged into the end of the heat dissipation tube 62 . A breathable membrane 11 is arranged inside the mounting hole 10 . The breathable membrane 11 can ensure the normal flow of air in the heat dissipation tube 62 , while preventing water vapor and dust from entering the heat dissipation tube 62 and affecting the normal heat dissipation of the heat dissipation tube 62 .

[0034] like Figure 6 As shown, the connection structure between the shell 2 and the base 1 includes a snap-in groove 12 arranged on both sides of the outer wall of the base 1 and a snap-in joint 13 arranged on both sides of the shell 2, the snap-in joint 13 is snap-fitted with the snap-in groove 12, and also includes a sealing plate 14 arranged on the inner side of the shell 2, and a plug-in groove 15 that is plug-fitted with both sides of the base 1 is formed between the sealing plate 14 and the inner walls on both sides of the shell 2, and a sealing gasket is arranged between the plug-in groove 15 and the base 1; a sealing block 16 that is plug-fitted with the opening at the end of the heat-conducting cover 6 is protruded from one side of the sealing head 9 relative to the heat-conducting cover 6, and the sealing block 16 abuts against the inner wall of the heat-conducting cover 6.

[0035] The card connector 13 is tightly matched with the card slot 12 to achieve a stable connection of the shell. A sealing plate 14 is also provided on the inner side of the shell 2. A plug-in slot 15 for plugging in the base 1 is formed between the sealing plate 14 and the inner wall of the shell 2, and a sealing gasket is provided between the base 1 and the plug-in slot 15 to improve the sealing of the shell. In addition, a sealing block 16 is protruding from the side of the sealing head 9 relative to the heat-conducting cover 6. The sealing block 16 is plugged and matched with the end of the heat-conducting cover 6 to ensure the sealing effect between the heat-conducting cover 6 and the sealing head 9. At the same time, the sealing head 9 is made of heat-conducting metal. By abutting against the heat dissipation pipe 62, the heat can be transferred to the sealing head 9 at both ends of the base 1, thereby improving the heat dissipation efficiency. In addition, the sealing blocks 16 located at both ends of the base 1 are difficult to be touched by the user during use, thereby avoiding scalding the user. Example

[0036] A lamp housing manufacturing process, the manufacturing steps are as follows: S1. Material preparation: polycarbonate is selected as the heat-insulating plastic for preparing the substrate 1 and the shell 2, wherein the polycarbonate used to make the shell 2 needs to be a transparent material; aluminum alloy is selected as the heat-conducting metal for preparing the heat-conducting cover 6; Polycarbonate, as the heat-insulating plastic of the base 1 and the shell 2, has excellent heat-insulating properties and mechanical strength, and can effectively isolate heat conduction, preventing heat from being conducted from the inside to the outer shell, thereby ensuring that the external temperature of the lamp is low and will not cause damage to the external environment or users. In addition, the use of transparent materials in polycarbonate for the shell 2 can maximize the light transmittance and ensure the light quality of the lamp when providing lighting.

[0037] Aluminum alloy is used as a heat-conducting metal material to make the heat-conducting cover 6 and the sealing head 9. It has good thermal conductivity and can quickly conduct the heat generated by the light-emitting element 3 to the heat dissipation pipe 62 to avoid heat accumulation around the light-emitting element 3, thereby improving the heat dissipation efficiency and extending the service life of the light-emitting element 3.

[0038] S2, injection molding: the base 1 and the shell 2 are manufactured by injection molding process, wherein the mold design needs to ensure that the base 1 has a U-shaped cross-sectional structure, and both ends of the base 1 need to be provided with open card slots for installing the sealing head 9; and the mold of the shell 2 needs to be designed with a card joint 13 structure for card connection, and a plug-in slot 15 for installing the sealing plate 14 and the heat-conducting cover 6 is formed on the inner side; The base 1 and the housing 2 are manufactured by injection molding, which can efficiently and accurately produce parts with complex shapes and precise dimensions, ensuring the structural stability of the base 1 and the housing 2. The U-shaped cross-sectional structure of the base 1 not only enhances the strength of the base 1, but also provides sufficient space for the internal installation of the light-emitting element 3 and the heat-conducting cover 6. The card connector 13 structure of the housing 2 is precisely matched with the open card slot of the base 1, ensuring that the assembled housing is tightly matched and the sealing performance of the lamp housing is guaranteed.

[0039] S3, processing of the heat-conducting cover 6: Aluminum alloy material is selected, and a connecting plate 61 is processed by a stamping process. The two ends of the connecting plate 61 are drilled with a drilling machine to form connecting holes for connecting with the mounting frame 4; then, a heat dissipation pipe 62 is processed by an extrusion molding process, and a plurality of heat dissipation pipes 62 are welded to each other and welded to a pair of connecting plates 61 by a welding process; The connection plate 61 is manufactured by a stamping process, which can ensure the accuracy and durability of the connection plate 61 and facilitate the fixation between the heat-conducting cover 6 and the mounting frame 4. The selection of aluminum alloy material further improves the thermal conductivity of the heat-conducting cover 6.

[0040] The extrusion molding process is used to manufacture the heat dissipation tube 62. While ensuring the strength of the material, it is possible to manufacture a tubular structure that is hollow inside and has a large heat dissipation surface area, thereby achieving higher heat dissipation efficiency.

[0041] The welding process connects a plurality of heat dissipation pipes 62 and the connection plate 61, thereby ensuring the structural stability of the heat dissipation system and the continuity of the heat conduction effect.

[0042] S4, processing and assembly of the Venturi tube 8: the Venturi tube 8 is processed by a turning process, and then put into the heat dissipation tube 62 for assembly and fixation, and then heat dissipation holes 621 are processed on the heat dissipation tube 62; The turning process is used to process the venturi tube 8, which ensures the shape accuracy of the venturi tube 8, so that it can effectively guide and accelerate the airflow. Through the venturi effect, the reduced middle design accelerates the airflow, enhances the gas convection speed in the heat dissipation pipe 62, and improves the heat dissipation efficiency.

[0043] The design of the heat dissipation hole 621 is combined with the venturi tube 8, so that the hot air can be quickly discharged through the heat dissipation hole 621 without being retained in the pipe, thereby avoiding heat accumulation.

[0044] S5, forming a sealing head 9 from aluminum alloy by die-casting, and processing a mounting hole 10 on the sealing head 9; then cutting the breathable membrane 11 into a size matching the mounting hole 10, and fixing it in the mounting hole 10 by bonding; The sealing head 9 is manufactured by die-casting process, which ensures that the sealing head 9 has a precise structure and high strength, and ensures the sealing fit between the base body 1 and the heat dissipation pipe 62 .

[0045] The breathable membrane 11 is fixed in the mounting hole 10 by bonding, which ensures the air pressure balance inside and outside the lamp housing, and prevents external dust or moisture from entering the housing, thereby improving the overall protection performance of the lamp. S6, assembling: assembling and fixing the finished parts; A.

Insert the sealing head 9 at both ends of the base 1, and connect the mounting hole 10 on the sealing head 9 with the end of the heat dissipation pipe 62 on the heat conductive cover 6; C. Finally, the housing 2 is clamped on the base 1 and the sealing head 9 is clamped and fixed.

[0046] S7, Quality inspection: Conduct sealing test and heat dissipation performance test on the assembled lamp housing; S8, Packaging: Clean the qualified products tested in S7 and then pack them with impact-resistant packaging materials.

[0047] Cleaning the lamp housing after passing the test can remove dust and impurities generated during the production and testing process, ensuring that the product remains clean when delivered to customers.

[0048] Using impact-resistant packaging materials for packaging can protect the lamp housing from external impact during transportation and avoid damage.
