It should be noted that the following will use the first detection information as the speed of the vehicle C, and the second detection information as The temperature of the light emitting unit 232 is taken as an example, but the invention is not limited to this, that is, other information can be received for evaluation.

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

Next, for example, in step S204: evaluating the first detection information and the second detection information, and obtaining an evaluation result, the corresponding light type may be selected according to the speed of the vehicle C as the evaluation reference value The output mode is used as the evaluation result. For example, assuming that the current vehicle C is traveling from a flat road to a high-speed road, and 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) , You need to switch the lighting mode, that is, you need to switch from basic lighting mode (C mode) or town road lighting mode (V rmode) to high-speed road lighting mode 2 (E2 mode), thereby switching to high-speed road 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 brightness value output when the node temperature of the light emitting unit 232 is 25°C is the 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 About 70% to 75% at 25°C. 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 is 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 the actual demand. In other words, the first detection information and the second detection information can be calculated by the second processing module to obtain an evaluation result. In detail, switching to highway mode (E mode) and the current brightness value may not be able to meet the actual demand as the evaluation result.

Then, for example, in step S206: generating an optimal fit based on the evaluation result In one embodiment of the light mode, the parameters of the lamp module 23 can be adjusted according to the evaluation result to generate the most suitable light mode. 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 to reduce the node temperature of the light emitting unit 232 and thereby increase the brightness value of the light emitting unit 232. In this way, the optimal cut-off mode can be selected according to the first detection information to switch to highway lighting mode 2 (E2 mode), and by adjusting the fan speed of the fan unit 233, the heat dissipation of the lamp module 23 is increased Efficiency to reduce the node temperature of the light-emitting unit 232, thereby increasing the brightness value of the light-emitting unit 232 to close to 100%. In addition, the brightness value can also be increased by increasing the total lumen 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 invention is not limited thereto. In addition, the brightness value may be increased by adjusting (increasing) the power of the driving unit 234. Therefore, in this embodiment, the parameters of the vehicle lamp module 23 are adjusted, and the corresponding light-type output mode selected after evaluating the first detection information is used as the most suitable light-type mode. In this way, when the brightness of the original light-emitting unit 232 is insufficient to meet the expressway lighting mode 2 (E2 mode), the requirements of the expressway lighting mode 2 (E2 mode) can be achieved by adjusting the parameters of the lamp module 23 .

Based on the above, it is worth noting that, in another embodiment of step S206: generating an optimal cut-off mode according to the evaluation result, a corresponding output mode according to the evaluation result may be output to generate the optimal cut-off mode. In other words, according to the current first detection information, it corresponds to the 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 high-speed road lighting mode 2 (E2 mode) can be directly switched to the high-speed road lighting mode 1 (E1 mode) to generate the most suitable 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, so as to meet the required lighting requirements and make up for the lack of brightness of the light emitting unit 232.

Based on the above, it is worth explaining that in step S206: generating a In yet another embodiment of the optimal cut-off mode, the parameters of the vehicle lamp module 23 can be adjusted according to the evaluation result and the corresponding light-type output mode is output to generate the optimal cut-off mode. In other words, compared to only adjusting the parameters of the lamp module 23 to generate the optimal cut-off mode or directly selecting (switching) the corresponding light-type output mode to generate the optimal cut-off mode, in this embodiment The parameters of the vehicle lamp module 23 can be adjusted at the same time and the corresponding light-type output mode can be further selected (switched) to produce the most suitable light-cut mode. Further, since the current brightness value of the light emitting unit 232 may not meet the actual demand, the fan speed of the fan unit 233 may be adjusted or the total lumen value of the light emitting unit 232 may be adjusted to increase the brightness value. At the same time, the original value The selected high-speed road lighting mode 2 (E2 mode) is switched to the high-speed road lighting mode 1 (E1 mode) to generate an optimal 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 high-speed road lighting mode (E mode), a Information in bad weather lighting mode (W mode) and corner lighting mode (T mode) (such as but not limited to when the light system S is abnormal), at this time, regardless of the 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-off mode is the basic lighting mode (C mode). In other words, in other embodiments, when the first detection information and the second detection information have conditions (such as, but not limited to, the brightness value of the current light-emitting unit 232 differs from the brightness value of the original light-emitting unit 232 by 10% When) occurs, the evaluation result can be directly determined as the need to switch to the basic lighting mode (C mode). In addition, when the damage of the fan unit 233 is detected, the evaluation result can be directly determined as the need to switch to the basic lighting mode (C mode), and the temperature parameter is continuously detected 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 cleaning function of the housing of the car light module 23 according to the regulations, so the detection module 24 can have a car light detection module The sensor of the group 23 housing, when the second detection information detected by the detection module 24 is that the headlight needs cleaning, it can output a clear Wash instructions to clean the housing of the car light module 23 to ensure driving safety.

In addition, please refer to FIG. 10 again, the characteristics of the fan unit 233 will be different with the change of different altitudes (or the change of the air pressure value). When the altitude is 0m, if the mass flow rate is 100%, when the altitude is 3000m, the wind flow will drop to 65%. Therefore, at an altitude of 3000m, fans with the same speed can only take up 65% of the heat at sea level. Therefore, at different altitudes, the fan unit 233 is used for 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 heat dissipation level. 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 value or air density, the rotation speed of the fan unit 233 can be further adjusted to generate A most suitable 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 lamp system S may also be included, wherein the control mode of the lamp system S may include an automatic In the control mode and a manual control mode, after the automatic control mode is selected, step S102 or step S202 can be executed. In addition, when selecting the manual control mode, 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 high-speed road lighting Mode (E mode), a bad weather lighting mode (W mode) or corner lighting mode (T mode)).
