Thereby achieving an increase in the adjustment effect of the plurality of lighting units.
In the embodiment of the present invention, the illumination device may be a front light, a rear light, a turn signal light, a fog light, or the like, and the illumination device may be an LED illumination member configured by a plurality of illumination units, and the light color and the color temperature of the plurality of illumination units may be the same or different. Because of the limitation of factors such as heat dissipation, substrate, encapsulation, the conventional specification of LED single-chip is the miniwatt, and based on the actual application demand, LED adopts the miniwatt chip to form the chip module that satisfies actual demand power through the form of series connection, parallel connection or series-parallel connection to participate in the application usually. Thus, the regulation of the output power or the output color temperature of the LED lighting device is actually the combination of light regulation and control realized by a plurality of single chips, so that a plurality of dimming modes can be generated. According to the embodiment of the invention, the speed acquisition and/or the ambient light brightness acquisition are combined, and the adjustment of the plurality of LED low-power chips in the LED lighting device is realized, so that the adjustment of the power intensity, the color temperature, the switch output and the like of the output light of the LED lighting device is realized, the overall control capability of the output light of the LED lighting device is improved, and the vehicle can run more safely and intelligently.

In one embodiment, a method for adjusting a lighting device of a vehicle is provided, which is exemplified by the application of the method to a lighting device control unit of a vehicle, and comprises the following steps:
and S210, acquiring the current running speed of the transport means.
The transportation means may include a locomotive, a passenger-cargo vehicle, an automobile, and the like, which travel on a road surface. The speed of the transport means in the driving process can be acquired through the speed acquisition unit, specifically, the speed acquisition unit can acquire real-time speed data of the transport means in the driving process in a wired or wireless mode, and the acquired real-time speed data is sent to the lighting device control unit, so that the lighting device control unit acquires the current driving speed of the transport means.
S230, determining target power corresponding to the current running speed according to a preset speed-power corresponding relation; the speed-power correspondence is a correspondence between a speed range and an illumination power.
The speed-power correspondence can be determined by running tests of the transport vehicle in different scenes. Through the running test of a certain transport tool, the number of the lighting power of the lighting device in which speed range or the proportion of the rated power of the transport tool can be obtained, so that the corresponding driver can clearly see various conditions in the front without influencing other pedestrians or transport tools, the lighting device can generate heat as low as possible, and the lighting device can save energy to the maximum extent. The above steps may determine a speed range in which the current running speed is located, and determine the lighting power corresponding to the speed range in which the current running speed is located as the target power. Wherein the target power is a total target power of the plurality of lighting units.
The speed-power correspondence may record the illumination power corresponding to each of the at least two speed ranges. 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, a speed range of 60 steps below corresponds to an illumination power of 60% of the rated power, a speed range of 60 steps above and 60 steps above corresponds to an illumination power of the rated power, and so on.
And S250, adjusting the output power of the lighting device according to the target power.

The total output power of the lighting device is adjusted to the lighting power matched with the current running speed, so that the lighting brightness provided by the lighting device is matched with the current running speed of the transport means, on the basis of ensuring the running safety performance, the problem of light pollution caused by dazzling due to high light efficiency when the current lighting devices such as semiconductor lighting and the like are applied to the transport means is solved, and the purposes of energy conservation and environmental protection can be achieved.
Specifically, when the running speed of the transportation vehicle is low, the heat dissipation of the lighting device is limited, so that the ambient temperature of the lighting device is high, the brightness required by a driver to observe the front is relatively low in the scene, the target power determined according to the speed-power correspondence is relatively low, and after the total output power of the lighting device is reduced according to the target power, the heat generated in the lighting process provided by the lighting device can be reduced, the heat dissipation performance of the lighting device is ensured, and the service life of the lighting device is prolonged; when the running speed of the transport vehicle is higher, the heat dissipation effect of the lighting device is improved, so that the ambient temperature of the lighting device is low, the brightness required by a driver for observing the front is relatively high, the target power determined according to the speed-power corresponding relation is relatively large, and the total output power of the lighting device is increased according to the target power, so that the lighting brightness is improved, the running safety of the transport vehicle can be ensured, the heat generated by the lighting device can be timely dissipated, and the purpose of prolonging the service life of the lighting device can be achieved.
According to the method for adjusting the illuminating device of the transport tool, the current running speed of the transport tool can be obtained in the running process of the transport tool, the target power corresponding to the current running speed is determined according to the preset speed-power corresponding relation, the output power of the illuminating device is adjusted according to the target power, the output power of the illuminating device is matched with the current running speed of the corresponding transport device, namely, the illumination brightness provided by the illuminating device is matched with the current running speed of the transport device, on the basis of ensuring the running safety performance, the purposes of saving energy, protecting environment and prolonging the service life of the illuminating device can be achieved, and the adjusting effect of the illuminating device is improved.
In one embodiment, the adjusting the output power of the lighting device according to the target power includes: and determining a target current according to the target power, and adjusting the current of the lighting device according to the target current so as to adjust the output power of the lighting device and adjust the output power of the lighting device. Specifically, a 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, thereby adjusting the output power of each lighting unit. For example: if the voltage of a single lighting unit is fixed, the total output power of the lighting device can be increased, that is, the brightness of the lighting device can be increased by increasing the current passing through the single lighting unit or making the sum of the current passing changes of a plurality of lighting units positive according to the formula P (output power) ═ U (voltage) × I (current). And vice versa.
According to the embodiment, the required target current can be determined according to the configuration characteristics of the lighting device when the lighting device outputs the target power, and the current passing through the light source in the lighting device is regulated to be the target current, so that the output power of the lighting device is the target power, and the accuracy in the regulation process is ensured.
In one embodiment, the adjusting the output power of the lighting device according to the target power includes: and determining a target voltage according to the target power, and adjusting the voltage of the lighting device according to the target voltage so as to adjust the output power of the lighting device. Specifically, a 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, the voltage of the single lighting unit is increased or the sum of the voltage changes of a plurality of lighting units is made positive according to the formula P (output power) ═ U (voltage) × I (current), so that the total output power of the lighting device can be increased, that is, the brightness of the lighting device can be increased. And vice versa.
According to the embodiment, the required target voltage can be determined when the lighting device outputs the target power according to the configuration characteristics of the lighting device, the voltage of the light source in the lighting device is regulated to the target voltage, the output power of the lighting device is made to be the target power, and the accuracy in the regulation process is guaranteed.
In one embodiment, the speed-power correspondence records a first illumination power corresponding to a first speed range and a second illumination power corresponding to a second speed range. Depending on the actual situation, the output power (illumination power) for more speed ranges can also be recorded.
The first speed range and the second speed range may be set according to configuration characteristics of the vehicle and a corresponding driving scenario, respectively. The first lighting power corresponding to the first speed range and the second lighting power corresponding to the second speed range may be determined according to driving tests of the respective vehicle in the respective driving scenarios. For example, the first speed range may be set to 60 steps or less, and the first illumination power may be set to 60% of the rated power; the second speed range may be set to 60 steps and 60 steps or more, and the second illumination power may be set to the rated power.
In this embodiment, the speed-power correspondence records the lighting powers corresponding to the two speed ranges, so that when the real-time driving speed of the transportation vehicle is detected, the target power of the lighting device is determined according to the speed-power correspondence, and the determination efficiency of the target power can be ensured.
In one embodiment, the speed-power correspondence records a first illumination power corresponding to a first speed range, a second illumination power corresponding to a second speed range, and a third illumination power corresponding to a third speed range.
The first speed range, the second speed range and the third speed range may be set according to configuration characteristics of the transportation vehicle and corresponding driving scenarios, 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 driving tests performed on the corresponding transportation vehicle in each driving scene. Such as: the first speed range can be set to be below 60 steps, the distance between the vehicle and the workshop is short, if the vehicles are all lighted at full power (such as rated power), the brightness of the lamps of the whole vehicle is too bright, so that a driver feels dazzling, serious light pollution exists, and simultaneously, the trouble and discomfort are caused to the life of people in the city; correspondingly, the first illumination power may be set to 60% of the rated power. The second speed range may be set to a speed range of 60 steps to 100 steps (including 60 steps and 100 steps), for example, 80 steps, and the lighting requirement of the vehicle for the vehicle lights is better if the lights are brighter according to the vehicle specifications, but the brighter lights are more likely to cause dazzling of the driver of the vehicle driving on the opposite side and greatly reduce the safety of the vehicle driving on the opposite side; correspondingly, the second illumination power may be set to 80% of the rated power. The third speed range may be a speed range of 100 steps or more, for example, 120 steps, and the lighting requirement of the vehicle for the lamp is better as it is brighter under the condition of meeting the vehicle specification, and the third lighting power at this time may be set as the rated power.
In this embodiment, the speed-power correspondence records the lighting powers corresponding to the three speed ranges, so that when the real-time running speed of the transportation vehicle is detected, the target power corresponding to the current running speed of the lighting device is determined according to the speed-power correspondence, the matching accuracy between the target power and the current running speed can be improved, and the adjustment effect of the lighting device is further improved.
In one embodiment, the lighting device comprises a plurality of lighting units; the adjusting the output power of the lighting device according to the target power includes: and adjusting the power of each lighting unit according to the power ratio corresponding to each lighting unit, so that the sum of the power of each lighting unit is the target power.
The upper power ratio 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 ratio, so that the sum of the power of each lighting unit is the target power, the lighting provided by the lighting device is still the lighting matched with the current running speed, and the adjusting effect of the lighting device can be ensured.
One lighting unit can be a light source, and a plurality of lighting units can have a plurality of different light colors or light color temperatures, so that the light output by the plurality of lighting units can be mixed to form different color temperatures, and the color temperature can be controlled in the lighting process. Specifically, as an embodiment, the method further includes: determining a target color temperature corresponding to the current running speed according to a preset speed-color temperature corresponding relation; recording color temperature parameters respectively corresponding to a plurality of sections of speed ranges according to the speed-color temperature corresponding relation; and then the output color temperature of each lighting unit in the lighting device can be adjusted according to the target color temperature.
Specifically, the specific method of adjusting the output color temperature of each lighting unit according to the target color temperature may be: respectively determining unit color temperature parameters of each lighting unit according to the target color temperature; and adjusting the color temperature parameters of the lighting units according to the color temperature parameters of the lighting units, so that the mixed color temperature of the lighting units is equivalent to the target color temperature.
The speed-color temperature correspondence can be determined by running tests of the transport vehicle in different scenes. Through a running test of a certain transport vehicle, it can be known that the color temperature parameter of the illumination device is set to be a color temperature value in which speed range of the transport vehicle, so that the illumination effect provided by the illumination device can be optimized. And recording color temperature parameters corresponding to at least two speed ranges respectively according to the speed-color temperature corresponding relation. Specifically, a speed range in which the current running speed is located may be determined, and the color temperature parameter corresponding to the speed range in which the current running speed is located may be determined as the target color temperature.
In one embodiment, the color characteristics of the plurality of lighting units may be different from each other, and after the target color temperature is determined, the color temperature ratio of each lighting unit may be determined according to the color characteristics of each lighting unit to determine the unit color temperature parameters of each lighting unit, so that the lighting device may provide lighting corresponding to the target color temperature through each lighting unit to improve the lighting effect of the lighting apparatus.
Specifically, taking the example that the lighting device includes two lighting units, the fixed color temperatures of the lighting units 1 and 2 are not adjustable, and the color temperature of the lighting device can be adjusted according to the following formula in the scene:
K3＝K1*(P1/P1+P2)+K2*(P2/P1+P2)。
wherein K3 is the mixed color temperature (adjustable), K1 is the fixed color temperature (non-adjustable) of the lighting unit 1, K2 is the fixed color temperature (non-adjustable) of the lighting unit 2, P1/P1+ P2, P2/P1+ P2 are the power duty ratio values (adjustable) of the lighting unit 1 and the lighting unit 2, respectively, and the sum of the duty ratio values is 1. It is understood that when the lighting device includes n lighting units, the formula for adjusting the color temperature of the lighting device may be adjusted adaptively, and is expressed as a power duty ratio value of the lighting unit k by Pk/P1+ P2+ … + Pn, and the sum of the power duty ratios of the n lighting units is 1.
If the output power of each lighting unit can change with the change of the speed, the number of the power duty ratio values of each lighting unit can also change with the change of the speed, which means that the color temperature K3 obtained according to the above formula can also change with the change of the speed. The adjustment may be as desired, including, for example:
in the mode 1, the output power is increased and the color temperature is increased when the speed is increased, the speed is in positive correlation with the output power, and the speed is in positive correlation with the color temperature of the light.
Mode 2, the output power is turned up and the color temperature is reduced when the speed is increased. The speed is in positive correlation with the output power, and the speed is in negative correlation with the light color temperature.
Mode 3, the output power is turned down and the color temperature increases when the speed increases. The speed is inversely related to the output power and positively related to the color temperature.
Mode 4, the output power is turned down and the color temperature is reduced when the speed is increased. The speed is inversely related to the output power and the speed is inversely related to the color temperature.
Mode 5, the output power is turned up and the color temperature is raised when the speed is reduced. The speed is inversely related to the output power and the speed is inversely related to the color temperature.
Mode 6, the output power is turned up and the color temperature is lowered when the speed becomes small. The speed is inversely related to the output power and positively related to the color temperature.
Mode 7, the output power is turned down and the color temperature is raised as the speed becomes smaller. The speed is positively correlated with the power and negatively correlated with the color temperature.
Mode 8, the output power is turned down and the color temperature is lowered when the speed becomes small. The speed is positively correlated with the power and the speed is positively correlated with the color temperature.
Wherein, the higher the output power is, the higher the brightness is; and the harm of the glare generated by low color temperature is lower than that of the glare generated by high color temperature, the light color temperature is reduced, the light penetration capability can be enhanced, and the visual field of the vehicle driver can be better ensured.
The color temperature of the corresponding lighting device can be adjusted according to the current running speed of the transport means, the strain capacity of the lighting device of the transport means to the change of factors such as external environment and weather is improved, the method is more applicable and safer, and the adjusting effect of the lighting device is further improved.
In one embodiment, the method further comprises: detecting the current environment brightness; if the current ambient brightness is greater than or equal to the brightness threshold, the lighting device is turned off, and automatic adjustment of the output power and the output color temperature of the lighting device is not required at the moment; and if the current ambient brightness is smaller than the brightness threshold, executing the step of acquiring the current running speed of the transport tool, and further executing the automatic adjustment of the output power and/or the output color temperature of the lighting device.
The current ambient brightness can be obtained by measuring with a brightness sensor arranged outside the transportation tool, and after the current ambient brightness is obtained by measuring with the brightness sensor, the current ambient brightness can be sent to the lighting device control unit, so that the lighting device control unit can detect the current ambient brightness. The brightness threshold value can be based on visual characteristic equipment of a driver, when the current environment brightness is greater than or equal to the brightness threshold value, the driver can clearly observe the front of the transport means without depending on illumination provided by the illumination device, and at the moment, the illumination device can be turned off to save energy, so that the adjustment mode of the illumination device is more environment-friendly; and when the current environment brightness is smaller than the brightness threshold value, executing the step of acquiring the current running speed of the transport tool so as to adjust the lighting device according to the current running speed of the transport tool and ensure the adjusting effect of the lighting device.
As an embodiment, one speed range in the speed-power correspondence corresponds to a plurality of lighting powers; if the current ambient brightness is less than the brightness threshold, the determining the target power corresponding to the current driving speed according to the preset speed-power correspondence includes: determining a plurality of initial target powers corresponding to the current running speed according to the speed-power corresponding relation; an initial target power matching the current ambient brightness is selected as the target power.
In the speed-power correspondence relationship, a speed range corresponds to a plurality of lighting powers, wherein each lighting power may correspond to a brightness range, for example, a first lighting power corresponding to a first speed range includes a lighting power a1 and a lighting power a2, a lighting power a1 corresponds to a first brightness range, and a lighting power a2 corresponds to a second brightness range, that is, the lighting power a1 and the lighting power a2 correspond to different brightness ranges; the second illumination power corresponding to the second speed range includes illumination power B1 and illumination power B2, illumination power B1 corresponds to the first brightness range, and the second illumination power B2 corresponds to the second brightness range, i.e., illumination power B1 and illumination power B2 correspond to different brightness ranges.
After obtaining the plurality of initial target powers corresponding to the current running speed, the brightness range where the current ambient brightness is located can be further identified, the initial target power corresponding to the identified brightness range is determined, and the determined initial target power is selected as the target power, so that the determined target power is more matched with the current running environment of the transport means, and the adjusting 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 also adjusted, and a speed interval and an ambient brightness interval for adjusting the output power are consistent with the speed interval and the ambient brightness interval for adjusting the output color temperature; the adjustment may also be asynchronous, that is, the speed interval and the ambient brightness interval for adjusting the output power and for adjusting the output color temperature may not be consistent, and the adjustment of the output power and the output color temperature may also be performed independently.
For ease of understanding, the manner in which the lighting device of the vehicle of the present invention is adjusted is illustrated below.
Scene one: and adjusting the total output power of the lighting device of the vehicle along with the speed change of the vehicle, and not adjusting the light color temperature of the lighting device.

p (output power) ═ U (voltage) × I (current);
K3＝K1*(P1/P1+P2)+K2*(P2/P1+P2)；

However, the sum of the output power variation of the plurality of lighting units is zero, and at this time, the output power of the whole lighting device does not change, and only the color temperature changes with the speed. The method specifically comprises the following situations: case 1, the speed increases the color temperature rise, showing that the speed is positively correlated with the color temperature; case 2, speed increase color temperature decrease, showing that speed is inversely related to color temperature; case 3, the speed decreases and the color temperature increases, showing that the speed and the color temperature are in a negative correlation; case 4, showing a decrease in the color temperature with a decrease in speed, the speed is positively correlated with the color temperature.
Scene four: the light switching function of each lighting unit is adjusted as the speed changes.
Specific examples thereof include: according to the speed change, each lighting unit is respectively provided with a switch adjusting function, for example, when the speed is low, part of the lighting units are turned on, other lighting units are turned off, and when the speed is high, all the lighting units are turned on, so that the switch adjustment of the lighting units under the speed change is realized, the energy consumption is saved, and the service life of the lighting units is prolonged.
Scene five: along with the change of the speed, the scene four is matched with the scene one, the scene two or the scene three, so that a richer adjusting function is realized.
Scene six: and a photosensitive sensing function of ambient light is added, so that an automatic adjusting mode of the lighting device or an automatic adjusting mode of the lighting device is automatically turned on according to the brightness of the ambient light before the adjusting functions related to the scene one, the scene two, the scene three, the scene four and the scene five are turned on.
Through the adjusting method of the lighting device of the transport tool, the driving mode which is more environment-friendly, more energy-saving and safer can be realized. From the lighting technology, the heat dissipation technical bottleneck of the lighting device of the delivery vehicle can be solved, the energy-saving and consumption-reducing light pollution problem of the delivery vehicle is also improved, and the intelligent upgrading of the lighting system of the delivery vehicle is facilitated.
