The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0047] See also Figure 1 to Figure 5 The present invention provides a control device for a nighttime high beam lamp, comprising a high beam lamp module 1, a display module 2, a light control module 3, a switch module 4, a heat dissipation module 5, a strong light detection module 6 and a control terminal 7, wherein the high beam lamp module 1 comprises a left high beam lamp unit 8 and a right high beam lamp unit 9, the light control module 3 comprises a light adjustment unit 10 and a light source focusing unit 11, the switch module 4 comprises a left lamp switch unit 12, a right lamp switch unit 13 and a full lamp switch unit 14, and the high beam lamp module 1, the display module 2, the light control module 3, the switch module 4, the heat dissipation module 5 and the strong light detection module 6 are all connected to the control terminal 7;

[0048] The left high beam lamp unit 8 is used for illuminating the left front of the vehicle;

[0049] The right high beam lamp unit 9 is used for illuminating the right front of the vehicle;

[0050] The display module 2 is used to indicate the on and off of the high beam module 1 through an indicator light;

[0051] The light adjustment unit 10 is used to ensure that the light output of the high beam lamp is parallel light;

[0052] The light source focusing unit 11 is used to ensure that the light can be accurately focused on the lens or reflector;

[0053] The left light switch unit 12 is used to turn the left high beam light unit 8 on and off;

[0054] The right light switch unit 13 is used to turn the right high beam light unit 9 on and off;

[0055] The full-lamp switch unit 14 is used to turn on and off the left high-beam lamp unit 8 and the right high-beam lamp unit 9 at the same time;

By dividing the high-beam module 1 into left and right high-beams and setting three switches at the same time, it has significant advantages in terms of improving night driving safety, reducing scattered light, providing flexible high-beam control, enhancing the driver's driving experience, and innovation and practicality. This effectively solves the technical problem that some high-end models have already used new technologies such as LED matrix headlights and projection digital headlights to improve the safety of night driving.

[0080] In this embodiment, the light intensity detection unit 23 detects the light intensity of the oncoming vehicle, and compares it with the set parameters through the data comparison unit 24. If the intensity is greater than the set parameters, a signal is sent to the timer unit 25, and the timer intermittently controls the auxiliary high beam unit 26 to light up and go out, thereby reminding the oncoming vehicle to turn off the high beam.

[0081] Furthermore, the control device for the nighttime high beam lamp further comprises an alarm module 27 and a data processing module 28, and both the alarm module 27 and the data processing module 28 are connected to the controller.

[0091] The preprocessing unit 33 is responsible for receiving the electrical signal from the temperature sensor and performing amplification, filtering and analog-to-digital conversion.

[0092] The microprocessing unit 34 is used to receive the digital signal from the signal processing unit and determine whether the temperature of the high beam lamp is too high according to a preset algorithm and rule.

[0093] In this embodiment, the preprocessing unit 33 converts the analog signal of the temperature sensor into a digital signal for subsequent digital processing and analysis. The above units work together to ensure that the high beam can issue an alarm in time when the temperature is too high, thereby avoiding potential safety hazards.
