Duty ratio/opening time of the corresponding three primary colors light source of colour temperature under several weather conditions is tested and marked
It is fixed, it is then stored, to which the mapping table for having obtained colour temperature-three primary colors light source opening time or duty ratio includes colour temperature, color
Correspondence between coordinate and three primary colors light source opening time or the data and three of duty ratio.
S304：According to the opening time of each in three primary colors light source in car light or duty ratio to three primary colors light source in car light
Switch control is carried out, so that the colour temperature of car light reaches target colour temperature.I.e.：When detecting corresponding weather conditions, calling prestores
Corresponding data value in the mapping table of colour temperature-three primary colors light source opening time or duty ratio, so as to realize colour temperature according to
The demand that environment is adjusted.
As shown in figure 5, by control each color (red, green and blue three primary colors light sources, i.e.,：RGB primaries
Source) opening time t1, t2, t3 or duty ratio, to realize power ratio that RGB three primary colors are strolled, and then realize different colors
Temperature control system,
As a specific example, the adjusting of different-colour as shown in figure 4, white light by color by red, green, blue
This three primary colors light source mixes.Color is defined by a hexadecimal notation, this symbol is by red, green and blue
Value composition (RGB).The minimum value of each color is 0 (hexadecimal：#00).Maximum value is 255 (hexadecimals：#FF), lead to
It crosses color and prepares the purpose for realizing color temperature adjustment, be described above restraint, colour temperature can be demarcated actually, but need to meet related headlamp
Laws and regulations requirement, when running environment be non-greasy weather gas (such as fine day), pass through be turned up colour temperature, promoted vehicle lamp brightness, when rainy day or mist
When its visibility is not high, colour temperature can be turned down, and then the penetration power for car light of deducting a percentage, to make car light can adapt in a variety of differences
Weather conditions, meet vehicle traveling demand.
Fig. 4 is recombined, when weather conditions are mist/haze sky, further includes：Judge the grade of mist/haze, wherein no
The step of grade of same mist/haze corresponds to different colour temperatures, and acquisition is adapted to the target colour temperature of current weather conditions wraps
It includes：The grade that acquisition is adapted to current mist/haze obtains target colour temperature.
Specifically, when the small greasy weather colour temperature can it is appropriate be higher than the big greasy weather when colour temperature, such as：Colour temperature is when the small greasy weather
3000K, colour temperature when the big greasy weather can be 2500K, to make the penetration power of car light disclosure satisfy that different bad weathers.
