[0033] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below.

[0039] A driving rectifier board 5 is arranged in the installation straight plug 3; the driving rectifier board 5 is electrically connected to the original vehicle ballast and the driving rectifier board 5 is connected to the LED lamp assembly 4 through a wire.
[0040] When working, the rectifier driving board 5 rectifies the power provided by the original vehicle ballast and supplies power to other components; after the LED lamp assembly 4 is driven by the power, the LED lamp 401 lights up and generates a lot of heat (such as Figure 6 As shown), the heat generated by the LED lamp 401 is transferred into the outer shell 1 made of cold-forged aluminum through the copper heat-conducting substrate 402 at a high speed.
[0041] The heat sink 2 rotates at high speed driven by electricity, driving the surrounding airflow to dissipate heat from the cold-forged aluminum body. The heat generated during the light emission of the LED lamp 401 is cooled by the cold-forged aluminum body outer shell 1 and the heat sink 2, which greatly reduces the heat loss of the LED lamp 401, thereby improving its light emission efficiency.
[0042] In this embodiment, the outer shell 1 includes an upper outer shell 101 and a lower outer shell 102; the LED lamp assembly 4 can be detachably installed between the upper outer shell 101 and the lower outer shell 102, which is convenient for disassembly and replacement. When some parts are damaged, they can be directly replaced, and the interchangeability is high.
[0043] In this embodiment, the upper shell 101 and the lower shell 102 are both provided with evenly distributed heat dissipation fins 1025; through this design, the heat dissipation fins 1025 increase the contact area between the outer shell 1 of the cold forged aluminum body and the air, thereby improving the heat dissipation efficiency of the cold forged aluminum body.
[0044] In this embodiment, the upper shell 101 and the lower shell 102 are both provided with a semicircular chuck 1023. The two semicircular chucks 1023 form a chuck 1023. The chuck 1023 cooperates with the installation position on the original vehicle assembly to facilitate installation and fixation with the vehicle.
[0045] In this embodiment, a PPT straight plug is provided on the installation straight plug 3, and the PPT straight plug is matched with the female plug on the original vehicle ballast. The PPT straight plug is connected with the female plug to realize the connection between the utility model and the original vehicle power supply, and realizes quick installation and matching.
[0046] In this embodiment, the upper shell 101 and the lower shell 102 are also provided with a substrate mounting groove 1021, a light source mounting groove 1022 and a connecting portion 1024; the copper heat-conducting substrate 402 is installed in the substrate mounting groove 1021; the LED lamp 401 is arranged in the light source mounting groove 1022; and the copper heat-conducting substrate 402 is tightly attached to the upper shell 101 and the lower shell 102; the mounting straight plug 3 is installed on the outer shell 1 through the connecting portion 1024. Through this design, the outer shell of the cold-forged aluminum body is fully in contact with the LED lamp assembly 4, which is convenient for taking away the heat of the LED lamp assembly 4.
[0047] In this embodiment, the upper shell 101, the lower shell 102 and one end of the copper heat-conducting substrate 402 are all provided with a connecting hole 1026, and the connecting holes 1026 of the upper shell 101 and the lower shell 102 are countersunk holes, and the countersunk holes are provided with internal threads. The upper shell 101, the lower shell 102 and the copper heat-conducting substrate 402 are connected together by the fixing member 6. Through this design, it is easy to install and disassemble the upper shell 101, the lower shell 102 and the copper heat-conducting substrate 402, making it convenient to assemble and replace accessories of the utility model.
[0048] In this embodiment, the copper thermally conductive substrate 402 is a copper thermally conductive substrate 402 .
[0049] In this embodiment, the heat dissipation device 2 is a turbo cooling fan.
[0050] In this embodiment, the installation straight plug 3 is installed at the end of the outer shell 1, and the outer shell 1 is provided with a notch, and the installation straight plug 3 and the notch form an air intake window 8. Through this design, the installation straight plug 3 is designed away from the LED lamp 401, so that the heat emitted by the LED lamp 401 is prevented from affecting the installation straight plug 3, and air enters the outer shell 1 of the cold forged aluminum body from the air intake window 8, and the heat of the cold forged aluminum body can be taken away by the turbo cooling fan.
[0051] The working principle and use process of the utility model: When working, the rectifier driving board 5 rectifies the power provided by the original vehicle ballast and supplies power to other components; after the LED lamp component 4 is driven by the power, the LED lamp 401 lights up and generates a lot of heat (such as Figure 6 As shown in FIG. 4 , heat generated by LED lamp 401 is transferred into the cold-forged aluminum body through the copper heat-conducting substrate 402 at high speed. The turbo cooling fan rotates at high speed under the drive of electricity, driving the surrounding airflow (such as Figure 7As shown), airflow enters through the air intake window 8 between the cold-forged aluminum body and the installation straight plug 3, and flows out from between the numerous cooling fins 1025 of the cold-forged aluminum body driven by the turbine cooling fan, and in the process, the heat dissipated on the surface of the fins by the cold-forged aluminum body is taken away; the heat generated during the light-emitting process of the LED lamp 401 is cooled by the cold-forged aluminum body and the turbine cooling structure, which greatly reduces the heat loss of the LED lamp 401, thereby improving its light-emitting efficiency; as the light-emitting efficiency of the LED lamp 401 is improved, the lighting brightness of the utility model is improved, so that the car installed with the utility model will also illuminate the road brighter and clearer during driving, reducing traffic accidents caused by the failure of the headlight 401 LED to illuminate the road clearly when the car is driving at night.
[0052] The beneficial effect is that the utility model improves the heat dissipation efficiency by using a cold-forged aluminum body with a higher heat dissipation coefficient and a turbo cooling fan, dissipates the heat of the copper thermal conductive substrate 402 and the LED lamp 401, reduces the overall temperature and heat loss of the LED lamp 401, improves the overall light effect, and improves the safety of vehicle driving.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
