Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0023] Example 1

[0024] like Figures 1-5 As shown, this is the first embodiment of the present invention. This embodiment provides a wide-angle LED automotive lamp module, including a housing 1. A lens 2 is provided on the front of the housing 1, and nozzles 3 are connected to the upper and lower ends of both sides of the front of the lens 2. An LED light panel 4 is provided in the inner cavity of the housing 1. Transmission holes 15 are connected to the upper and lower ends of both sides of the front of the housing 1. A connecting box 5 is fixedly connected to the back of the housing 1, and a fan 6 is provided in the inner cavity of the connecting box 5. A hose 7 is connected to the air outlet of the fan 6, and a heating tube 8 is connected to the air inlet of the fan 6. An electric heating wire is provided in the inner cavity of the heating tube 8.

[0025] like Figures 1-5As shown, the LED light panel 4 can be placed through the housing 1, and the LED light panel 4 can operate to generate light emission. The light can be focused through the lens 2 to improve the illumination. The fan 6 is protected through the connecting box 5. The operation of the fan 6 allows external airflow to enter the inner cavity of the heating tube 8, and the electric heating wire inside the heating tube 8 operates to generate heat to heat the airflow. The hot airflow is transmitted through the fan 6 to the inner cavity of the hose 7, and the hose 7 transmits the hot airflow to the inner cavity of the transmission hole 15. The transmission hole 15 transmits the hot airflow to the nozzle 3, and then the nozzle 3 sprays the hot airflow onto the surface of the lens 2, which can disperse the fog condensed on the surface of the lens 2, thereby preventing fog condensation from obstructing light transmission and affecting driving safety and lighting clarity.

[0026] Example 2

[0027] Reference Figure 1 , 3 4 and 5 are the second embodiment of this utility model, which is based on the previous embodiment.

[0028] In this embodiment, the end of the hose 7 away from the air outlet of the blower 6 is connected to the inner cavity of the transmission hole 15, and the inner cavity of the transmission hole 15 is connected to the inner cavity of the nozzle 3.

[0029] Ventilation grooves 11 are provided on both sides of the bottom of the inner cavity of the cover 1. A heat sink 12 is fixedly connected to the bottom of the cover 1. The top of the heat sink 12 extends through the inner cavity of the cover 1 and contacts the LED light board 4.

[0030] A filter screen 9 is fixedly connected to the inner cavity of the heating tube 8, and an interception screen is fixedly connected to the inner cavity of the venting groove 11.

[0031] like Figure 1 , 3 As shown in Figures 4 and 5, the hose 7 is connected to the transmission hole 15, and the transmission hole 15 is connected to the nozzle 3, which facilitates the transmission of hot air. The hot air can be sprayed onto the surface of the lens 2 through the nozzle 3 to remove the mist. The ventilation groove 11 allows ventilation to the inner cavity of the housing 1, ensuring natural airflow. The heat sink 12 absorbs and exchanges the heat generated by the operation of the LED light board 4, achieving heat dissipation for the LED light board 4. The filter screen 9 filters impurities in the airflow entering the heating tube 8, ensuring the cleanliness of the airflow. The interception screen intercepts external impurities, preventing them from entering the housing 1.

[0032] Example 3

[0033] Reference Figure 3 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0034] In this embodiment, a sealing gasket 10 is fixedly connected to the front of the cover 1, and the side of the sealing gasket 10 away from the cover 1 is in contact with the lens 2.

[0035] Both sides of the front of the lens 2 are movably connected to the threaded sleeves 14 via bearings, and both sides of the front of the cover 1 are fixedly connected to the screws 13. The screws 13 penetrate the inner cavity of the threaded sleeves 14 and are threadedly connected to the inner cavity of the threaded sleeves 14.

[0036] like Figure 2 As shown, when the lens 2 is connected to the housing 1, the lens 2 will move to one side of the housing 1, and the screw 13 will pass through the lens 2 and enter the inner cavity of the screw sleeve 14. As the screw sleeve 14 rotates, since the screw sleeve 14 and the screw 13 are threadedly connected, the screw 13 will gradually pass through the inner cavity of the screw sleeve 14 until the lens 2 contacts the sealing gasket 10, thereby realizing the connection operation. At the same time, the sealing gasket 10 will ensure the sealing of the connection between the housing 1 and the lens 2.

[0037] In use, the LED light panel 4 first generates light, which is then transmitted to the lens 2. The lens 2 focuses the light, thereby improving illumination and facilitating vehicle illumination at night or in adverse conditions. When fog condenses on the surface of the lens 2, the fan 6 allows external airflow to enter the inner cavity of the heating tube 8. The heating wire inside the heating tube 8 generates heat to heat the airflow. The hot airflow is then transmitted by the fan 6 to the inner cavity of the hose 7, which in turn transmits the hot airflow to the inner cavity of the transmission hole 15. The transmission hole 15 then transmits the hot airflow to the nozzle 3. The nozzle 3 sprays hot air onto the surface of the lens 2, which disperses the fog that condenses on the surface of the lens 2, thus preventing fog from condensing and obstructing light transmission, affecting driving safety and lighting clarity. When the lens 2 needs to be replaced after long-term use, by rotating the screw sleeve 14, since the screw 13 and the screw sleeve 14 are threadedly connected, the screw 13 can be gradually disengaged from the inner cavity of the screw sleeve 14 during the rotation of the screw sleeve 14, and the screw sleeve 14 drives the lens 2 to gradually separate from the cover 1 and the sealing gasket 10, thereby realizing the disassembly of the lens 2. Conversely, the above operation can be used to reinstall it.

[0038] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. 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. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.

[0039] Although the utility model has disclosed as above with preferable embodiments, it is not used to limit the utility model. Those skilled in the art to which the utility model belongs can make various changes and decorations without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model is accurate according to the definition of the claims.
