In order to make the purpose, technical solutions, and advantages of this application clearer, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the application, and not used to limit the application.

The method for adjusting the lighting device of a transportation tool provided in the present application can be applied to a moving automobile and other transportation tools, and can be specifically applied to the lighting device control unit of the above-mentioned transportation tool. The lighting device of the transportation means includes a plurality of lighting units. The above-mentioned lighting device control unit can obtain the current driving speed of the transportation means, determine the target power corresponding to the current driving speed according to the preset speed-power correspondence, and adjust the lighting device according to the target power. The output power of each lighting unit makes the brightness of the lighting provided by the lighting device match the current driving speed of the vehicle. In addition, the above-mentioned lighting device control unit can also determine the target color temperature corresponding to the current driving speed according to the preset speed-color temperature correspondence, and adjust the output color temperature of each lighting unit in the lighting device according to the target color temperature, so that the lighting color temperature provided by the lighting device is also Match the current speed of the vehicle. As a result, the adjustment effect of multiple lighting units is improved.

In the embodiment of the present invention, the lighting device may be a front lamp, a rear lamp, a turn signal lamp, a fog lamp, etc., and the lighting device may be an LED lighting component, which is composed of multiple lighting units. The light color and color temperature can be the same or different. Due to the limitations of heat dissipation, substrate, packaging and other factors, the conventional specifications of LED single chips are all low power. Based on actual application requirements, LEDs usually adopt low-power chips to meet the actual demand power in the form of series, parallel or series-parallel hybrid connection. Chip modules to participate in the application. In this way, the adjustment of the output power or the output color temperature of the LED lighting device is actually a combination of light adjustment of multiple single chips, so a variety of dimming modes can be generated. The embodiment of the present invention, combined with the collection of speed and/or ambient light brightness, adjusts multiple LED low-power chips in the LED lighting device, so as to achieve the power and color temperature of the output light of the LED lighting device.

The use of LED lighting devices not only overcomes the current situation that the halogen lamp of the vehicle is transparent but not bright, but also overcomes the embarrassment of the xenon vehicle being bright but not bright.

In one embodiment, a method for adjusting a lighting device of a transportation tool is provided. Taking the method applied to a lighting device control unit of a transportation tool as an example for description, the method includes the following steps:

S210: Acquire the current driving speed of the transportation means.

The above-mentioned means of transportation may include vehicles running on the road such as locomotives, passenger and freight vehicles, and automobiles. The speed of the transportation means in the driving process can be collected by the speed collection unit. Specifically, the speed collection unit can collect the real-time speed data of the transportation means in the driving process in a wired or wireless manner, and send the collected real-time speed data to the lighting The device control unit enables the above-mentioned lighting device control unit to obtain the current driving speed of the vehicle.

S230: Determine the target power corresponding to the current driving speed according to the preset speed-power correspondence; the speed-power correspondence is the correspondence between the speed range and the lighting power.

The above-mentioned speed-power correspondence can be determined according to the driving test of the vehicle in different scenes. Through the driving test of a certain means of transport, we can know which speed range of the means of transport is, how much the lighting power of the lighting device is set to, or what proportion of the rated power is set, which can ensure that the corresponding driver can see clearly the front This kind of situation does not affect other pedestrians or vehicles, and can also make the lighting device generate as low heat as possible, so that the lighting device can achieve maximum energy saving. The above steps can determine the speed range of the current driving speed, and determine the lighting power corresponding to the speed range of the current driving speed as the target power. Wherein, the target power is the total target power of the multiple lighting units.

The aforementioned speed-power correspondence can record the lighting power corresponding to at least two speed ranges respectively. Specifically, a speed range with a small speed value corresponds to a small lighting power, and a speed range with a large speed value corresponds to a large lighting power; for example, recording the speed range below 60 steps corresponds to the lighting power of 60% of the rated power, and 60 steps The speed range above 60 miles corresponds to the rated power, the lighting power, and so on.

S250: Adjust the output power of the lighting device according to the target power.

Specifically, the output power of each lighting unit in the lighting device can be adjusted according to the target power. The output power of each lighting unit in the lighting device can be adjusted by adjusting the current and/or voltage. The total output power of the lighting device is adjusted to the lighting power that matches the current driving speed, so that the brightness of the lighting provided by the lighting device matches the current driving speed of the vehicle. On the basis of ensuring driving safety performance, the current semiconductor is reduced. Light pollution caused by dazzling caused by high luminous efficiency when lighting devices such as lighting are applied to transportation tools can achieve the purpose of energy saving and environmental protection.

Specifically, when the driving speed of the transportation tool is low, the heat dissipation of the lighting device is limited, so the ambient temperature of the lighting device is high, and the brightness required by the driver to observe the front in this scene is relatively low, which is determined according to the speed-power correspondence relationship The target power of the lighting device is relatively small. After the total output power of the lighting device is reduced according to the target power, the heat generated during the lighting device provided by the lighting device can be reduced, the heat dissipation performance of the lighting device, and the service life of the lighting device can be prolonged; When the driving speed of the tool is high, the heat dissipation effect of the lighting device is improved, so the ambient temperature of the lighting device is low, and the brightness required by the driver to observe the front is relatively high, and the target power determined according to the speed-power correspondence relationship is relatively large According to the target power, increase the total output power of the lighting device to increase the brightness of the lighting, which not only ensures the safety of transportation, but also enables the heat generated by the lighting device to be dissipated in time, which can extend the service life of the lighting device the goal of.

The above-mentioned method for adjusting the lighting device of the transportation means can obtain the current driving speed of the transportation means during the driving process, and determine the target power corresponding to the current driving speed according to the preset speed-power correspondence relationship, so as to adjust the lighting device according to the target power Output power, matching the output power of the lighting device with the current driving speed of the corresponding transportation device, that is, matching the lighting brightness provided by the lighting device with the current driving speed of the transportation device, on the basis of ensuring the driving safety performance, can achieve The purpose of energy saving and environmental protection and prolonging the service life of the lighting device has improved the adjustment effect of the lighting device.

In one embodiment, adjusting the output power of the lighting device according to the target power includes: determining the target current according to the target power, and adjusting the current of the lighting device according to the target current, thereby adjusting the output power of the lighting device, thereby adjusting the output of the lighting device power. Specifically, the target current of each lighting unit in the lighting device may be determined according to the target power, and the current of each lighting unit may be adjusted according to the target current, so as to adjust the output power of each lighting unit. For example: if the voltage of a single lighting unit is fixed, according to the formula P (output power) = U (voltage) * I (current), by increasing the through current of a single lighting unit, or changing the through current of multiple lighting units If the sum of the quantities is a positive number, the total output power of the lighting device can be increased, that is, the brightness of the lighting device can be adjusted brighter. The opposite is similar.

This embodiment can determine the required target current when the lighting device outputs the target power according to the configuration characteristics of the lighting device, and adjust the current passing through the light source in the lighting device to the target current, so that the output power of the lighting device is the target power to ensure the adjustment Accuracy in the process.

In one embodiment, adjusting the output power of the lighting device according to the target power includes: determining the target voltage according to the target power, and adjusting the voltage of the lighting device according to the target voltage, thereby adjusting the output power of the lighting device. Specifically, the target voltage of each lighting unit in the lighting device may be determined according to the target power, and the voltage of each lighting unit may be adjusted according to the target voltage, thereby adjusting the output power of each lighting unit. For example: if the passing current of a single lighting unit is fixed, according to the formula P (output power) = U (voltage) * I (current), by increasing the voltage of a single lighting unit, or changing the voltage of multiple lighting units The sum is a positive number, and the total output power of the lighting device can be increased, that is, the brightness of the lighting device can be adjusted brighter. The opposite is similar.

This embodiment can determine the required target voltage when the lighting device outputs the target power according to the configuration characteristics of the lighting device, adjust the voltage of the light source in the lighting device to the target voltage, and make the output power of the lighting device the target power to ensure that the adjustment process Accuracy.

In one embodiment, the aforementioned speed-power correspondence records the first lighting power corresponding to the first speed range and the second lighting power corresponding to the second speed range. According to the actual situation, you can also record the output power (lighting power) corresponding to more speed ranges.

The above-mentioned first speed range and second speed range can be set according to the configuration characteristics of the transportation means and the corresponding driving scene respectively. The first lighting power corresponding to the first speed range and the second lighting power corresponding to the second speed range can be determined according to the driving test performed by the corresponding transportation means in each driving scene. For example, the first speed range can be set to 60 steps or less, the first lighting power can be set to 60% of the rated power; the second speed range can be set to 60 steps and above, and the second lighting power can be set to the rated power.

The speed-power correspondence in this embodiment records the lighting powers corresponding to the two speed ranges respectively, so that when the real-time driving speed of the vehicle is detected, the target power of the lighting device is determined according to the above-mentioned speed-power correspondence to ensure the target power Deterministic efficiency.

In one embodiment, the speed-power correspondence records the first lighting power corresponding to the first speed range, the second lighting power corresponding to the second speed range, and the third lighting power corresponding to the third speed range.

The above-mentioned first speed range, second speed range and third speed range can be set according to the configuration characteristics of the transportation means and the corresponding driving scene respectively. The first lighting power corresponding to the first speed range, the second lighting power corresponding to the second speed range, and the third lighting power corresponding to the third speed range may be determined according to the driving test performed by the corresponding vehicle in each driving scene. For example: the first speed range can be set to 60 steps or less, and the distance between the car and the workshop is relatively close. If the car is turned on with sufficient power (for example, the rated power), the brightness of the lights in the entire car sea will be too bright, making the driver feel dazzling Dazzling, there is serious light pollution, and at the same time it will cause trouble and discomfort to people's lives in the city; correspondingly, the first lighting power can be set to 60% of the rated power. The second speed range can be set to the speed range of 60 to 100 steps (including 60 and 100 steps). For example, it is 80 steps. The vehicle's demand for the lighting of the car lights is to be as bright as possible under the premise of complying with vehicle regulations. However, the brighter the light is, the more likely it is to dazzle the driver of the opposite vehicle, which greatly reduces the safety of the opposite vehicle; correspondingly, the second lighting power can be set to 80% of the rated power. The third speed range can be set to a speed range above 100 miles, such as 120 miles. The vehicle's lighting requirements for the lights are as bright as possible under the premise of complying with vehicle regulations. At this time, the third lighting power can be set as rated power.

In this embodiment, the speed-power correspondence records the lighting powers corresponding to the three speed ranges respectively, so that when the real-time driving speed of the vehicle is detected, the target power corresponding to the current driving speed of the lighting device is determined according to the above-mentioned speed-power correspondence. The matching accuracy between the target power and the current driving speed can be improved, and the adjustment effect of the lighting device can be further improved.

In one embodiment, the above-mentioned lighting device includes a plurality of lighting units; the above-mentioned adjusting the output power of the lighting device according to the target power includes: adjusting the power of each lighting unit according to the corresponding power ratio of each lighting unit, so that the power of each lighting unit And is the target power.

The upper power percentage can be set according to the performance characteristics of each lighting unit, and the power of each lighting unit is adjusted according to the power percentage, so that the sum of the power of each lighting unit is the target power, so that the lighting provided by the lighting device is still at the current driving speed Matching lighting can ensure the adjustment effect of the lighting device.

One lighting unit can be a light source, and multiple lighting units can have a variety of different light colors or light color temperatures, so the light output by multiple lighting units can be mixed to produce different color temperatures, so color temperature can also be controlled during the lighting process . Specifically, as an embodiment, the above method further includes: determining the target color temperature corresponding to the current driving speed according to the preset speed-color temperature correspondence; the speed-color temperature correspondence recording the color temperature parameters corresponding to the multiple speed ranges; The target color temperature adjusts the output color temperature of each lighting unit in the lighting device.

Specifically, the specific method for adjusting the output color temperature of each lighting unit according to the target color temperature may be: determining the unit color temperature parameters of each lighting unit according to the target color temperature; adjusting the color temperature parameters of each lighting unit according to the color temperature parameters of each unit, so that multiple lighting The mixed color temperature of the unit is equivalent to the target color temperature.

The above-mentioned speed-color temperature correspondence can be determined according to the driving test of the vehicle in different scenes. Through the driving test of a certain transportation means, it can be known that the speed range of the transportation means and which color temperature parameter is set to the lighting device can make the lighting effect provided by the lighting device optimal. The aforementioned speed-color temperature correspondence records the color temperature parameters corresponding to at least two speed ranges respectively. Specifically, the speed range of the current driving speed can be determined, and the color temperature parameter corresponding to the speed range of the current driving speed can be determined as the target color temperature.

In one embodiment, the color characteristics of multiple lighting units may be different. After determining the target color temperature, the color temperature ratio of each lighting unit can be determined according to the color characteristics of each lighting unit to determine the unit color temperature parameter of each lighting unit , So that the lighting transposition can provide lighting corresponding to the target color temperature through each lighting unit, so as to improve the lighting effect of the lighting device.

Specifically, taking the lighting device including two lighting units as an example, the fixed color temperature of lighting unit 1 and lighting unit 2 is not adjustable. In this scenario, the color temperature of the lighting device can be adjusted according to the following formula:

K3=K1*(P1/P1+P2)+K2*(P2/P1+P2).

K3 is the mixed color temperature (adjustable), K1 is the fixed color temperature of lighting unit 1 (not adjustable), K2 is the fixed color temperature of lighting unit 2 (not adjustable), P1/P1+P2, P2/P1+P2 respectively Is the power duty cycle value of lighting unit 1 and lighting unit 2 (adjustable), and the sum of the duty cycle values is 1. It is understandable that when the lighting device includes n lighting units, the formula for adjusting the color temperature of the lighting device can be adjusted appropriately. Pk/P1+P2+...+Pn is expressed as the power duty cycle value of the lighting unit k, and n lighting The sum of the power duty of the unit is 1.

If the output power of each lighting unit can change with the change of speed, then the power duty ratio value of each lighting unit can also change with the change of speed, which means that the color temperature K3 derived from the above formula can also change with the speed The changes change. The adjustment method can be determined according to needs, for example, including:

Method 1, when the speed increases, the output power is increased and the color temperature increases, the speed and the output power are positively correlated, and the speed and the light color temperature are positively correlated.

Method 2, when the speed increases, the output power is increased and the color temperature decreases. Speed and output power are positively correlated, and speed and light color temperature are negatively correlated.

Mode 3, when the speed increases, reduce the output power and increase the color temperature. Speed and output power are negatively correlated, and speed and color temperature are positively correlated.

Mode 4, when the speed increases, the output power is reduced and the color temperature decreases. Speed and output power are negatively correlated, and speed and color temperature are negatively correlated.

Mode 5, the speed becomes smaller and the output power is increased and the color temperature rises. Speed and output power are negatively correlated, and speed and color temperature are negatively correlated.

Mode 6, when the speed becomes smaller, the output power is increased and the color temperature is lowered. Speed and output power are negatively correlated, and speed and color temperature are positively correlated.

Mode 7, when the speed decreases, the output power is reduced and the color temperature increases. Speed and power are positively correlated, and speed and color temperature are negatively correlated.

Mode 8, the speed becomes smaller and the output power is reduced and the color temperature is lowered. Speed and power are positively correlated, and speed and color temperature are positively correlated.

Among them, the greater the output power, the greater the light brightness; and the glare produced by low color temperature is less harmful than the glare produced by high color temperature, and the color temperature of the light is reduced, and the penetrating ability of the light can be enhanced. To ensure the vision of the driver of the own vehicle.

This embodiment can adjust the color temperature of the corresponding lighting device according to the current driving speed of the vehicle, which improves the ability of the lighting device of the vehicle to respond to changes in factors such as the external environment and weather. It is more applicable and safer, and further improves the performance of the lighting device. Adjustment effect.

In one embodiment, the above method further includes: detecting the current environment brightness; if the current environment brightness is greater than or equal to the brightness threshold, turning off the lighting device, at this time there is no need to perform automatic adjustment of the output power and output color temperature of the lighting device; if the current environment If the brightness is less than the brightness threshold, the step of obtaining the current driving speed of the vehicle is executed, and then the output power and/or output color temperature of the lighting device are automatically adjusted.

The above-mentioned current environment brightness can be measured by a brightness sensor installed outside the transportation tool. After the above-mentioned brightness sensor measures the current environment brightness, the above-mentioned current environment brightness can be sent to the lighting device control unit, so that the lighting device control unit detects the current environment brightness. The above-mentioned brightness threshold can be based on the driver's visual characteristic equipment. When the current ambient brightness is greater than or equal to the brightness threshold, the driver can clearly observe the front of the vehicle without relying on the lighting provided by the lighting device. At this time, the lighting device can be turned off , To save energy and make the lighting device adjustment method more environmentally friendly; when the current environment brightness is less than the brightness threshold, perform the step of obtaining the current driving speed of the transportation means to adjust the lighting device according to the current driving speed of the transportation means to ensure the adjustment of the lighting device effect.

As an embodiment, one speed range in the foregoing speed-power correspondence relationship corresponds to multiple lighting powers; if the current environmental brightness is less than the brightness threshold, the foregoing determining the target power corresponding to the current driving speed according to the preset speed-power correspondence includes: The speed-power correspondence determines multiple initial target powers corresponding to the current driving speed; an initial target power that matches the current environmental brightness is selected as the target power.

In the above-mentioned speed-power correspondence, one speed range corresponds to multiple lighting powers, where each lighting power can respectively correspond to a brightness range. For example, the first lighting power corresponding to the first speed range includes lighting power A1 and lighting power A2, lighting power A1 Corresponding to the first brightness range, lighting power A2 corresponds to the second brightness range, that is, lighting power A1 and lighting power A2 correspond to different brightness ranges; the second lighting power corresponding to the second speed range includes lighting power B1 and lighting power B2, lighting power B1 corresponds to the first brightness range, and the second lighting power B2 corresponds to the second brightness range, that is, the lighting power B1 and the lighting power B2 correspond to different brightness ranges.

After obtaining multiple initial target powers corresponding to the current driving speed, the brightness range of the current environmental brightness can be further identified, and then the initial target power corresponding to the identified brightness range can be determined, and the determined initial target power is selected as the target power. The determined target power is more matched with the current driving environment of the vehicle, and the adjustment effect of the lighting device is further provided.

It should be noted that, in the embodiment of the present invention, the adjustment of the output power and/or the output color temperature of the lighting device may be synchronous adjustment, that is, the output power is adjusted while the output color temperature is adjusted, and the speed range and the output color temperature are adjusted. The ambient brightness range is consistent with the speed range used to adjust the output color temperature and the ambient brightness range; it can also be asynchronous adjustment, that is, the speed range used to adjust the output power and the speed range used to adjust the output color temperature, and the ambient brightness range can be inconsistent. The adjustment of the output color temperature can also be performed independently of each other.

For ease of understanding, the following describes the adjustment method of the lighting device of the transportation tool of the present invention as an example.

Scenario 1: As the speed of the vehicle changes, the total output power of the lighting device of the vehicle is adjusted, and the light color temperature of the lighting device is not adjusted.

Scenario 2: As the speed changes, both the total output power of the lighting device and the light color temperature of the lighting device are adjusted.

Scenario 3: As the speed changes, the total output power of the lighting device is not adjusted, only the color temperature can be adjusted.

For example: according to the formula:

P (output power) = U (voltage) * I (current);

K3=K1*(P1/P1+P2)+K2*(P2/P1+P2);

As the speed changes, the output power of each lighting unit may change accordingly, and the power duty cycle value of each lighting unit also changes accordingly, so the color temperature changes. However, the sum of the output power changes of multiple lighting units is zero. At this time, the output power of the entire lighting device will not change, only the color temperature changes with speed. Specifically, it includes the following situations: Case 1, speed increases and color temperature increases, which is expressed as a positive correlation between speed and color temperature; Case 2, speed increases and color temperature decreases, which is manifested as a negative correlation between speed and color temperature; Case 3, speed decreases and color temperature rises High, it shows that the speed and color temperature are negatively correlated; Case 4 shows that the speed decreases and the color temperature decreases, and the speed and color temperature are positively correlated.

Scenario 4: As the speed changes, adjust the light switch function of each lighting unit.

Specific example: according to the speed change, realize the switch adjustment function for each lighting unit. For example, when the speed is low, some lighting units are turned on, and other lighting units are turned off. When the speed is high, all the lighting units are turned on. Switch adjustment to save energy consumption and extend the service life of the lighting unit.

Scene 5: As the speed changes, Scene 4 cooperates with Scene 1, Scene 2 or Scene 3 to achieve richer adjustment functions.

Scene 6: Add the light-sensitive sensing function of ambient light, so that the automatic adjustment mode of the lighting device can be automatically turned on according to the brightness of the ambient light before the adjustment functions related to scene 1, scene 2, scene 3, scene 4, and scene 5 are turned on , Or the automatic adjustment mode of the lighting device.

Through the method for adjusting the lighting device of a transportation tool in the above embodiment, a more environmentally friendly, energy-saving, and safer driving mode can be realized. In terms of lighting technology, it can not only solve the heat dissipation technology bottleneck of the vehicle lighting device, but also improve the energy saving and light pollution problems of the vehicle, which is conducive to the intelligent upgrade of the vehicle lighting system.

These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution of these sub-steps or stages The sequence is not necessarily performed sequentially, but may be performed alternately or alternately with at least a part of other steps or sub-steps or stages of other steps.
