Light illumination of the region 200 only under environment light source irradiation is ambient light illumination, by the difference of comprehensive illumination and ambient light illumination then
Can determine that out lighting illumination intensity.
Finally, only shone with target area according to the dutycycle of the electric current of accessed supply lighting source 20 or amplitude
Light illumination under the irradiation of Mingguang City source 20, determines that the dutycycle of the electric current of supply lighting source 20 or amplitude are only existed with target area
The default mapping relations formula of the light illumination under the irradiation of lighting source 20.
As lighting illumination intensity is to make the difference to obtain by comprehensive illumination and ambient light illumination, environment light source control can be prevented effectively from
The interference of bright illumination, so as to obtain dutycycle or the amplitude of corresponding lighting illumination intensity and electric current, to ensure based on corresponding
The dutycycle or amplitude gained of lighting illumination intensity and electric current presets the accuracy of mapping relations formula.
In actual applications, can be right by the dutycycle of the electric current of the supply lighting source of acquisition unit quantity or amplitude institute
Light illumination of the target area that answers only under lighting source irradiation；The accounting for of electric current further according to the supply lighting source of unit quantity
Light illumination of the target area corresponding to empty ratio or amplitude only under lighting source irradiation determines the electric current of supply lighting source
Light illumination only under the irradiation of lighting source 20 of dutycycle or amplitude and target area 200 default mapping relations formula.
For example, when default mapping relations formula is determined by abovementioned steps, obtain lighting illumination intensity for 500 luxs, and obtain
The dutycycle of electric current is 50%, then it is 500 lux/50% that can obtain the lighting illumination intensity corresponding to unit quantity dutycycle, i.e.,
For 10 lux/1%, the lighting illumination intensity of 10 luxs is can adjust by the dutycycle of adjustment 1%, before can determine based on this
State mapping relations formula.
S423, target duty ratio or target amplitude is judged whether in the predetermined current parameter area of lighting source 20, if
It is, execution step S424, if it is not, execution step S425.
The electric current that predetermined current parameter area be able to can be born according to lighting source 20 is preset, due to target area
200 lighting environment may be more complicated, for example, 200 range blanking light source of target area, 20 hypertelorism, in fact it could happen that target is accounted for
Empty ratio or target amplitude already exceed its maximum operating currenbt, and for example, have more intense light source around target area 200, can
Can there is target duty ratio or when target amplitude has been zero, i.e., when the lighting source 20 is closed, still cannot be by target area
The light illumination in domain is adjusted to object illumination.
It should be noted that applying in general lighting environment and target area 200 and lighting source in lighting device 100
20 distance also cannot too far when, step S423 and follow-up step S425 can be omitted in means of illumination, be will not be described here.
S424, by supply lighting source electric current adjust to target duty ratio or target amplitude so that target area is only
Light illumination under lighting source irradiates is located in the range of target difference.
After aforementioned process determines target duty ratio or target amplitude, the supply illumination of main power source 10 can be directly adjusted
The electric current of light source 20 so as to meet target duty ratio or target amplitude.
S425, in a wired or wireless fashion first is preset hint instructions and send to default prompting device 70 or default terminal and set
