[0002] Car headlights, also known as car headlamps, are the eyes of a car. They are not only related to the appearance of a car owner, but also closely related to safe driving at night or in bad weather conditions. The use and maintenance of car lights cannot be ignored. At night or in dark weather, car headlights directly affect the driving of the car. High-quality car headlights help improve driving safety and reduce accident rates.

[0003] However, the existing automobile headlight lens decorative frames are not practical. After the headlights are used for a long time at night, a large amount of heat will be generated. If the heat is not dissipated in time, it may be damaged. In addition, the existing lens decorative frames with heat dissipation holes have poor sealing performance. On rainy days, water is easily allowed to enter the frame, causing damage to the electrical components of the headlights. Utility Model Content

[0018] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0019] Reference Figure 1-4The utility model embodiment is a decorative frame for a secondary reflector of a vehicle lamp, which comprises: a decorative frame body 1, a lamp body 2, and a heat dissipation fan 3. The lamp body 2 penetrates the rear wall of the decorative frame body 1. A temperature detector is installed on the inner wall of the decorative frame body 1. The temperature detector is connected to the control of the external control system. A cooling plate is arranged below the heat dissipation fan 3. The cooling plate and the heat dissipation fan 3 are both connected to the control system. A ventilation cavity 101 is provided inside the decorative frame body 1. A ventilation port 103 is provided at the bottom end of the decorative frame body 1. The rear side of the inner wall of the decorative frame body 1 is along the periphery of the lamp body 2. A plurality of blowing holes 102 are provided, and the heat dissipation fan 3 is arranged below the ventilation cavity 101. The inner wall of the decorative frame body 1 is evenly provided with heat dissipation holes 105. The outer wall of the decorative frame body 1 is provided with heat dissipation holes 104 corresponding to the heat dissipation holes 105. The corresponding heat dissipation holes 105 and the inner walls of the heat dissipation holes 105 and 104 are penetrated and fixedly connected with ventilation pipes 4. The ventilation pipes 4 are all arranged in an inclined manner, and the inclined lower ends of the ventilation pipes 4 are all facing the heat dissipation holes 104. The vents 103, the ventilation cavity 101, the blowing holes 102 and the ventilation pipes 4 are interconnected. By means of the heat dissipation fan 3, blowing hole 102, ventilation pipe 4 and ventilation cavity 101, when the temperature sensor in the frame detects that the temperature of the lamp body 2 reaches a threshold value, a signal is transmitted to the control unit, and the control unit starts the refrigeration plate for cooling, and at the same time starts the motor of the heat dissipation fan 3 to drive the heat dissipation fan 3 to rotate, and blows the cold air into the ventilation cavity 101 through the vent 103, so as to quickly cool down the decorative frame body 1, and at the same time, the cold air blows around the lamp body 2 through the blowing hole 102, so as to quickly cool down the lamp body, and finally the gas is discharged from the decorative frame through the ventilation pipe 4, so as to have high cooling efficiency and improve the service life of the lamp body; the ventilation cavity 101 and ventilation pipe 4 are set, and the ventilation cavity 101 improves the cooling efficiency while ensuring the sealing of the decorative frame body 1, and the inclined ventilation pipe 4 has a heat dissipation hole 104 at its lower end facing the outside, which is opposite to the flow direction of rainwater, thereby avoiding rainwater from flowing into the frame, ensuring the heat dissipation function while having a certain waterproof property.

[0020] Working principle: When in use, when the temperature sensor in the frame detects that the temperature of the lamp body 2 reaches the threshold, the signal is transmitted to the control unit, and the control unit starts the refrigeration sheet for cooling, and at the same time starts the motor of the heat dissipation fan 3 to drive the heat dissipation fan 3 to rotate, and blows the cold air into the ventilation cavity 101 through the vent 103, so as to quickly cool down the decorative frame body 1, and at the same time, the cold air blows around the lamp body 2 through the blowing hole 102, so as to quickly cool down the lamp body, and finally the gas is discharged from the decorative frame through the ventilation pipe 4, with high cooling efficiency, thereby improving the service life of the lamp body. When it rains, because the lower end of the ventilation pipe 4 faces the external heat dissipation hole 104, it is opposite to the flow direction of the rainwater, thus preventing the rainwater from flowing into the frame.

[0021] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
