Under this understanding, all specific subordinate limitations of the terms or methods should be considered as part of the invention and should not be narrowly interpreted or biased simply because the specification does not disclose such a specific limitation. Similarly, provided that it is logically feasible, the order of the steps in the method is flexible and varied, and all specific subordinate limitations in the broad concepts of various terms or methods fall within the scope of protection of this invention.

[0042] First embodiment:

[0043] like Figures 1-2 As shown, this embodiment provides a method for heat dissipation of LED vehicle lights, including S11-S15, wherein:

[0044] S11. Obtain LED vehicle light instructions and obtain actual test data of LED vehicle lights.

[0045] In this embodiment, the LED vehicle light controller stores different LED vehicle light commands and corresponding LED vehicle light control programs, which facilitates the LED vehicle light to implement the corresponding vehicle light functions according to actual needs. Based on the vehicle light command, the system retrieves preset detection data corresponding to the vehicle light command for comparison with the actual detection data. The required detection data includes brightness data and rotation speed data. The brightness and rotation speed of the LED vehicle light are detected respectively, which is convenient for comparison with the preset detection data to determine whether the current actual rotation speed reaches the required rotation speed under the current actual brightness. This facilitates subsequent adjustment of the output rotation speed based on the rotation speed data.

[0046] In some embodiments, the LED vehicle lights can be integrated high beam and low beam headlights. The LED vehicle light commands can be obtained by inputting the corresponding LED vehicle light commands through an LED vehicle light command input device installed on the device, or by installing a detector on the vehicle to generate the corresponding LED vehicle light commands based on the current vehicle status and road information.

[0047] After determining the LED headlight command, the preset detection data of the LED headlight command is read. The detection data includes the brightness data and speed data corresponding to the LED headlight command, so as to facilitate the comparison between the actual detection data and the preset detection data.

[0048] In the acquisition of the actual detection data of the LED car lamp, the light source detection device and the rotating speed sensor can be used for detection. The light source detection device can convert the light signal in the LED car lamp into an electric signal to obtain the actual brightness data of the LED car lamp. The rotating speed sensor can detect the actual working voltage of the fan and convert the actual working voltage into the actual rotating speed of the fan to obtain the actual rotating speed data of the LED car lamp, so as to compare with the preset detection data.

[0049] As a specific solution but not limitation, the LED car lamp instruction includes at least the low beam sub-instruction, the high beam sub-instruction, the daytime running light sub-instruction, the turn signal sub-instruction, and the fog lamp sub-instruction.

[0050] Since the required brightness of the LED car lamp is different under different LED car lamp instructions, in order to ensure that the LED car lamp can accurately dissipate heat, the LED car lamp instruction is refined, and the corresponding brightness data and rotating speed data under each instruction are input on the controller, so that the LED car lamp can control the rotating speed according to different LED car lamp instructions.

[0051] The LED car lamp instruction is refined into the low beam sub-instruction, the high beam sub-instruction, the daytime running light sub-instruction, the turn signal sub-instruction, and the fog lamp sub-instruction, and the corresponding preset detection data under each sub-instruction is input.

[0052] S12, according to the LED car lamp instruction, determine the preset detection data corresponding to the LED car lamp instruction, the detection data includes brightness data, rotating speed data.

[0053] There are many ways to set the preset test data, only a few of which are listed below. Generally speaking, when the LED car lamp is shipped, the manufacturer will provide the LED car lamp lumen value parameter. Similarly, when the fan is shipped, the manufacturer will provide the fan voltage and rotating speed parameters. According to the above parameters, the lumen difference and rotating speed difference of the LED car lamp can be obtained, and the difference ratio between the two can be calculated according to the lumen difference and rotating speed difference to calculate the relationship between the lumen value and the rotating speed value.

[0054] For example, the maximum lumen value of the LED car lamp is 6000 lumens, the lumen difference of the LED car lamp is 6000, the maximum rotating speed of the fan is 3000 RPM, and the rotating speed difference of the fan is 3000. The difference ratio is 6000 ÷ 3000 = 2, so the fan rotating speed needs to be increased by 0.5 RPM for every 1 lumen increase of the LED car lamp. For details, see Figure 2 .

[0055] For the car light such as the turn signal light which needs to flash, the fan speed is changed in real time according to the change of the lumen value, which is easy to cause the fan failure, therefore, when setting this kind of car light, a time period can be set, the maximum lumen value in the time period can be detected, the corresponding required fan speed can be calculated, and the fan speed is adjusted accordingly, the time period can be the time required for the turn signal light to turn on and off, and the turn signal light flashing time program can be adjusted accordingly.

[0056] In some embodiments, since the light source in the LED car light needs to extend into the lampshade for use, the heat generated by the LED car light with the lampshade is higher at the same brightness, so that the required fan speed should also be increased accordingly, therefore, the preset test data can be obtained by manual experiment, the required fan speed at each stage of brightness of the LED car light is detected, so as to ensure the optimal correspondence between the brightness and the speed of the LED car light, and the preset test data and the actual test data are compared, so as to determine whether the current LED car light speed matches the current LED car light brightness.

[0057] S13, comparing whether the actual test data matches the preset test data.

[0058] After obtaining the actual test data and the predicted test data, the two data are compared, the current actual brightness data and the current actual speed data are determined, the corresponding preset brightness data is found according to the actual brightness data, the preset speed data corresponding to the actual brightness data is found in the predicted test data, and the preset speed data is compared with the current actual speed data, whether they are equal, so as to determine whether the current LED car light speed matches the current LED car light brightness.

[0059] S14, when the actual test data and the preset test data do not match, the speed compensation amount is obtained according to the actual test data and the preset test data, in this embodiment, the actual test data and the preset test data are compared, so as to determine whether the current LED car light speed is the speed corresponding to the current LED car light brightness, when the actual test data and the preset test data do not match, it indicates that the current LED car light speed is not the speed corresponding to the current LED car light brightness, the compensation amount between the actual test speed data and the preset test speed data, i.e. the speed compensation amount, is obtained by calculation, so that the controller can adjust the speed of the LED car light according to the speed compensation amount, so as to ensure that the current LED car light speed is the speed corresponding to the current LED car light brightness.

[0060] S15, a speed adjustment signal is sent to the controller, and the speed in the LED vehicle lamp is adjusted according to the speed compensation amount, so that the data matches the preset detection data; in this embodiment, the speed in the LED vehicle lamp is adjusted according to the size of the speed compensation amount, so that the speed in the LED vehicle lamp is adjusted to the required speed, so that the current speed of the LED vehicle lamp reaches the speed suitable for the current brightness of the LED vehicle lamp.

[0061] Further, when the speed data in the actual detection data is less than the speed data in the preset detection data, a speed increase signal is sent to the controller, and the speed in the LED vehicle lamp is increased according to the speed compensation amount; in this embodiment, the speed data in the actual detection data is less than the speed data in the preset detection data, indicating that the current speed in the LED vehicle lamp is less than the speed data in the preset detection data, indicating that the current speed in the LED vehicle lamp is too low, so the speed is adjusted according to the size of the speed compensation amount, so that the speed in the LED vehicle lamp is increased to reach the optimal speed suitable for the current brightness.

[0062] Further, when the speed data in the actual detection data is greater than the speed data in the preset detection data, a speed decrease signal is sent to the controller, and the speed in the LED vehicle lamp is decreased according to the speed compensation amount; in this embodiment, the speed data in the actual detection data is greater than the speed data in the preset detection data, indicating that the current speed in the LED vehicle lamp is greater than the speed data in the preset detection data, indicating that the current speed in the LED vehicle lamp is too high, so the speed is adjusted according to the size of the speed compensation amount, so that the speed in the LED vehicle lamp is decreased to reach the optimal speed suitable for the current brightness.

[0063] As a specific solution rather than a limitation, in order to prevent the LED light source from failing after long-term use of the LED vehicle lamp, so that the brightness of the LED light source is low but the heat generation is large; the detection data includes temperature data, when the actual detection temperature data is greater than the preset detection data, a speed adjustment signal is sent to the controller. A temperature sensor is arranged in the LED vehicle lamp for detecting the temperature inside the LED vehicle lamp, so as to detect whether the temperature inside the LED vehicle lamp exceeds the preset detection data, for example, the optimal working temperature of the LED vehicle lamp is 60℃, and the temperature data of the preset detection data is set to 55℃, when the temperature sensor detects that the actual temperature inside the LED vehicle lamp exceeds 55℃, a speed adjustment signal is sent to the controller, and the controller increases the fan speed to the maximum speed after receiving the speed adjustment signal of the temperature sensor, so as to accelerate the heat dissipation efficiency of the LED vehicle lamp, and avoid the problem that the brightness of the LED light source is low but the heat generation is large when the LED light source fails.

[0066] The determination module 110 is connected with the first acquisition module 120, and is used for determining preset detection data corresponding to an LED vehicle lamp instruction according to the instruction of the LED vehicle lamp, wherein the detection data includes brightness data and rotation speed data;

[0067] In the embodiment, the preset detection data corresponding to different LED vehicle lamp instructions is stored on a controller of the LED vehicle lamp, the corresponding preset detection data is automatically called by the system through acquisition of the corresponding LED vehicle lamp instruction, and is used for comparison with actual detection data, the required detection data includes the brightness data and the rotation speed data, the brightness and the rotation speed of the LED vehicle lamp are detected respectively, comparison with the preset detection data is facilitated, and whether the current actual rotation speed reaches the required rotation speed under the current actual brightness is determined, and subsequent adjustment of the output rotation speed is facilitated according to the rotation speed data.

[0068] The first acquisition module 120 is connected with the second acquisition module 130, and is used for acquiring the LED vehicle lamp instruction.

[0069] After the LED vehicle lamp instruction is determined, the preset detection data of the LED vehicle lamp instruction is read, and the detection data includes corresponding brightness data and rotation speed data under the LED vehicle lamp instruction. The second acquisition module is connected with the generation module, and is used for comparing whether the actual detection data and the preset detection data match

[0070] The second acquisition module 130 is connected with the generation module 140, and is used for comparing whether the actual detection data and the preset detection data match, and generating a rotation speed compensation amount according to the actual detection data and the preset detection data.

[0071] The generation module 140 is connected with the control module 150, and is used for corresponding rotation speed according to the received rotation speed adjustment signal.

[0072] The first control unit 151 is used for sending a rotation speed increase signal to the controller when the rotation speed data in the actual detection data is less than the rotation speed data in the preset detection data, and increasing the rotation speed in the LED vehicle lamp according to the rotation speed compensation amount.

When the actual detection data and the preset detection data are different, it indicates that the current rotation speed in the LED vehicle lamp does not match the current brightness of the LED vehicle lamp, that is, the current rotation speed in the LED vehicle lamp is too fast or too slow. According to the rotation speed compensation amount, the rotation speed in the LED vehicle lamp is adjusted to reach the optimal rotation speed matched with the current brightness, so as to improve the accuracy of the heat dissipation system.
