In addition, the first detection information can be processed The first processing module 11 of the device 1 is received, and the second detection information can be received by the second processing module 21. It should be noted that in the following, the first detection information is the speed of vehicle C, and the second detection information is The temperature of the light-emitting unit 232 is taken as an example, but the present invention is not limited to this, that is, other information can be received for evaluation.

Then, for example, in step S203: the first detection information is transmitted to the vehicle light device 2, or the second detection information is transmitted to the processing device 1, so as to evaluate the first detection information by the vehicle light device 2 or the processing device 1. In the step of detecting the information and/or the second detecting information, the first detecting information (the speed of the vehicle C) may be transmitted to the second processing module 21 of the vehicle lamp device 2.

Then, for example, in step S204: evaluating the first detection information and the second detection information to obtain an evaluation result, the corresponding light type can be selected according to the speed of the vehicle C as the reference value for evaluation The output mode is used as the evaluation result. For example, suppose that the current vehicle C is traveling from a flat road to a highway, and when the speed of the vehicle C is accelerated from 50km/hr to 105km/hr, the second processing module 21 evaluates the current speed (105km/hr) , The lighting mode needs to be switched, that is, the basic lighting mode (C mode) or the urban road lighting mode (V rmode) needs to be switched to the highway lighting mode 2 (E2 mode), thereby switching to the highway lighting mode 2 (E2 mode) is the result generated after evaluating the first detection information. At the same time, the temperature of the light-emitting unit 232 of the vehicle lamp module 23 can be used as a reference value for evaluation. For example, if the output brightness value of the light-emitting unit 232 is 25°C as a reference (100%), when the node temperature of the light-emitting unit 232 is 150°C, its output brightness value will decrease, and its brightness value It is about 70% to 75% at 25℃. In addition, when the node temperature of the light-emitting unit 232 is between 105° C. and 130° C., its output brightness value will decrease, and its brightness value will be about 85% to 87% at 25° C. Therefore, since the current light-emitting unit 232 has been lit for a period of time, and the temperature of the light-emitting unit 232 has risen, the current brightness value may not meet actual requirements. In other words, the first detection information and the second detection information can be calculated by the second processing module to obtain the evaluation result. In detail, switching to the highway lighting mode (E mode) and the current brightness value may not be able to meet the actual demand is the result of the evaluation obtained.

Then, for example, in step S206: generate an optimal In one embodiment of the light pattern, the parameters of the vehicle lamp module 23 can be adjusted according to the evaluation result to generate the most suitable cut light pattern. In other words, the fan speed of the fan unit 233 can be adjusted to increase the heat dissipation efficiency of the vehicle lamp module 23, so as to reduce the node temperature of the light emitting unit 232, thereby increasing the brightness value of the light emitting unit 232. In this way, the most suitable cut-light mode can be switched to highway lighting mode 2 (E2 mode) selected according to the first detection information, and the fan speed of the fan unit 233 is adjusted to increase the heat dissipation of the vehicle lamp module 23 Efficiency to reduce the node temperature of the light-emitting unit 232, thereby increasing the brightness value of the light-emitting unit 232 to nearly 100%. In addition, the brightness value can also be increased by increasing the total lumens value of the light-emitting unit 232, that is, other light-emitting units 232 that have not been turned on can be further turned on to increase the brightness value, and the present invention is not limited to this. In addition, the brightness value can also be increased by adjusting (raising) the power of the driving unit 234. Therefore, in this embodiment, the parameters of the vehicle lamp module 23 are mainly adjusted, and the corresponding light output mode selected after evaluating the first detection information is used as the most suitable cut light mode. In this way, when the original light-emitting unit 232 has insufficient brightness and cannot meet the highway lighting mode 2 (E2 mode), the requirements of the highway lighting mode 2 (E2 mode) can be achieved by adjusting the parameters of the vehicle lamp module 23 .

In view of the above, it is worth noting that in another embodiment of step S206: generating an optimal cut light pattern according to the evaluation result, a corresponding light output pattern may be output according to the evaluation result to generate the optimal cut light pattern. In other words, according to the current first detection information, it corresponds to highway lighting mode 2 (E2 mode), but according to the current second detection information, due to the current brightness of the light-emitting unit 232 The value may not meet the actual needs. Therefore, the originally selected highway lighting mode 2 (E2 mode) can be directly switched to the highway lighting mode 1 (E1 mode) to generate the most suitable cut light mode, but the present invention does not This is limited. Therefore, in this embodiment, the lighting mode is directly switched without adjusting the parameters of the vehicle lamp module 23 to meet the required lighting requirements and compensate for the insufficient brightness of the light-emitting unit 232.

In view of the above, it is worth noting that in step S206: generate a In another embodiment of the optimal cut light mode, the parameters of the vehicle lamp module 23 can be adjusted according to the evaluation result and the corresponding light output mode can be output to generate the optimal cut light mode. In other words, compared to only adjusting the parameters of the vehicle lamp module 23 to generate the most suitable cut light mode or directly select (switch) the corresponding light output mode to generate the most suitable cut light mode, in this embodiment The parameters of the vehicle lamp module 23 can be adjusted at the same time, and the corresponding light output mode can be further selected (switched) to generate the most suitable cut light mode. Furthermore, because the current brightness value of the light-emitting unit 232 may not meet the actual demand, the fan speed of the fan unit 233 or the total lumens value of the light-emitting unit 232 can be adjusted to increase the brightness value. At the same time, the original The selected highway lighting mode 2 (E2 mode) is switched to highway lighting mode 1 (E1 mode) to generate the most suitable cut light mode.

Next, please refer to FIG. 10 again. In other embodiments, the first detection information may also be that it cannot be switched to a town road lighting mode (V mode), a highway lighting mode (E mode), and a Information in bad weather lighting mode (W mode) and curve lighting mode (T mode) (for example, but not limited to when the car light system S is abnormal). At this time, regardless of the information content of the second detection information, the evaluation result It can be directly determined that it is necessary to switch to the basic lighting mode (C mode), so the current most suitable cut-light mode is the basic lighting mode (C mode). In other words, in other embodiments, when the first detection information and the second detection information are in condition (for example, but not limited to, the brightness value of the current light-emitting unit 232 differs by 10% from the original light-emitting unit 232 When (time) occurs, the evaluation result can be directly judged as the need to switch to the basic lighting mode (C mode). In addition, when it is detected that the fan unit 233 is damaged, the evaluation result can directly determine that it is necessary to switch to the basic lighting mode (C mode), and continuously detect the temperature parameters to adjust (reduce) the power of the driving unit 234.

In addition, please refer to FIG. 10 again. If the brightness of the light-emitting unit 232 is greater than 2000 lumens, it must also have the function of cleaning the housing of the car light module 23 according to the law. Therefore, the detection module 24 can have a detection car light model. The sensor of group 23 housing, when the second detection information detected by the detection module 24 is that the headlight needs cleaning, it can also output a clear The washing instruction is used to clean the housing of the lamp module 23 to ensure driving safety.

In addition, please refer to FIG. 10 again. With the change of different altitudes (or the change of the air pressure), the characteristics of the fan unit 233 will also be different. When the altitude is 0m, if the mass flow rate is 100%, when the altitude is 3000m, the wind flow rate will drop to 65%. Therefore, at an altitude of 3000m, a fan with the same speed can only take away 65% of the heat at sea level. Therefore, at different altitudes, the fan unit 233 is used to perform forced convection heat dissipation, and the rotation speed of the fan unit 233 needs to be corrected, that is, the rotation speed of the fan unit 233 is increased to maintain the same level of heat dissipation. In other words, when the first detection information or the second detection information is the current altitude information, by evaluating the current altitude, air pressure or air density, the rotation speed of the fan unit 233 can be further adjusted to generate An optimal cut light mode.

In addition, it is worth noting that according to the embodiment of the present invention, before step S102 and step S202, a control mode for selecting the vehicle light system S may also be included, wherein the control mode of the vehicle light system S may include an automatic A control mode and a manual control mode, when the automatic control mode is selected, step S102 or step S202 can be executed next. In addition, when the manual control mode is selected, the user can adjust the required light mode according to the needs (such as but not limited to a basic lighting mode (C mode), a town road lighting mode (V mode), a highway lighting Mode (E mode), a bad weather lighting mode (W mode) or curve lighting mode (T mode)).

Furthermore, the present invention can utilize a technical solution that simultaneously evaluates the first detection information and the second detection information, while simultaneously considering the state of the vehicle C and the performance of the lamp module 23 State and produce the most suitable cut light mode suitable for the current situation.

Furthermore, since the first signal transceiving module 12 of the processing device 1 can be wirelessly coupled to the second signal transceiving module 22 of the vehicle lamp device 2, there is no need to further open a hole in the vehicle C for cable supply Thread through.
