It is scheduled on the lux 950-1050, it might even be possible to which reasonable illumination range can also directly be some determination value, such as 1000 luxs.
When ambient light illumination changes and changes more than default environmental range, show that environment light source changes greatly,
Such variation is easy so that the synthesis illumination of target area 200 can not adapt to human eye protection demand or can not adapt to operative scenario
Demand.
Default environmental range can be according to the rationally reasonable change of illumination range where the synthesis illumination of target area 200
Change amount is preset, such as user needs to do the fine work of such as reading in target area 200, then can be by reasonable illumination model
It encloses and is set as 1000 luxs.The reasonable change amount of reasonable illumination range equally need to protect demand or operative scenario need according to human eye
It asks to set, such as is arranged to 5% floating range, then according to reasonable illumination range and the floating range it can be concluded that rationally shining

Lighting illumination intensity under light source irradiation within the scope of target difference so that lighting illumination intensity at this time and ambient light illumination and object illumination
In range.
As shown in connection with fig. 6, in embodiments of the present invention, step S42 specifically comprises the following steps.
S421, a difference within the scope of target difference is randomly selected, as target difference.
When object illumination range is some determination value, then target difference range is also determining value, then can be directly by mesh
Mark difference range is used as target difference.
When object illumination range is an interval range, an optional value mesh can be used as within the scope of the object illumination
Mark difference.Preferably, it can choose the median of object illumination range as target difference.
S422, default mapping relations formula is inquired according to target difference, determines the duty ratio of electric current corresponding with target difference
Or amplitude, as target duty ratio or target amplitude, default mapping relations formula includes the electric current of mutual corresponding lighting source
Duty ratio or amplitude and the target area only light illumination under lighting source irradiation.
It could be used for changing the illumination of 20 emitted light of lighting source by adjusting the duty ratio or amplitude of electric current, this is
Technology well known to those of ordinary skill in the art, this will not be repeated here.
In embodiments of the present invention, it is provided with default mapping relations formula, default mapping relations formula can store to controller
In 40.This presets the duty ratio that corresponding electric current is provided in mapping relations formula or amplitude and light illumination, lighting source 20
When using current duty cycle in the mapping relations formula or current amplitude, the illumination of the target area under the lighting source 20 irradiation
Illumination is then the duty ratio or amplitude mapped light illumination in default mapping relations formula with used electric current.
In practical applications, aforementioned default mapping relations formula can be determined as follows, in case shining in the present invention
Bright method call.
Firstly, obtaining target area 200 only in environment light by the first illuminance transducer 30 when lighting source 20 is shut down
Irradiation lower light illumination in source is to get to ambient light illumination.
Secondly, obtaining target area 200 in environment light source by the first illuminance transducer 30 when lighting source 20 is operated
The duty of the electric current of supply lighting source 20 is obtained with the synthesis illumination under 20 common irradiation of lighting source and by controller 40
Than or amplitude.Since lighting source 20 is successively to shut down and operate, time interval is little between two operations, therefore passes through this
When two steps execute, environment light source is identical.
In turn, the light illumination and target area by target area 200 under environment light source and 20 common irradiation of lighting source
Domain 200 only environment light source irradiation under light illumination difference, as target area only lighting source 20 irradiation under light
Line illumination.Light illumination of the target area 200 under environment light source and 20 common irradiation of lighting source is comprehensive illumination, target
Light illumination of the region 200 only under environment light source irradiation is ambient light illumination, then by the difference of comprehensive illumination and ambient light illumination
It can determine that out lighting illumination intensity.
Finally, only being shone according to the duty ratio of the electric current of accessed supply lighting source 20 or amplitude with target area
Light illumination under the irradiation of Mingguang City source 20 determines that the duty ratio of the electric current of supply lighting source 20 or amplitude only exist with target area
The default mapping relations formula of light illumination under the irradiation of lighting source 20.
Since lighting illumination intensity is to make the difference to obtain by comprehensive illumination and ambient light illumination, it is possible to prevente effectively from environment light source compares
The interference of bright illumination, so that the duty ratio or amplitude of corresponding lighting illumination intensity and electric current are obtained, to guarantee based on corresponding
The accuracy of mapping relations formula is preset obtained by the duty ratio or amplitude of lighting illumination intensity and electric current.
It in practical applications, can be right by the duty ratio or amplitude institute that obtain the electric current of the supply lighting source of unit quantity
The target area answered only lighting source irradiation under light illumination；It is accounted for further according to the electric current of the supply lighting source of unit quantity
Light illumination of the target area only under lighting source irradiation corresponding to sky ratio or amplitude determines the electric current of supply lighting source
Duty ratio or amplitude and the target area 200 only light illumination under the irradiation of lighting source 20 default mapping relations formula.
For example, obtaining lighting illumination intensity is 500 luxs, and is obtained when determining default mapping relations formula by abovementioned steps
The duty ratio of electric current is 50%, then lighting illumination intensity corresponding to available unit quantity duty ratio is 500 lux/50%, i.e.,
For 10 lux/1%, the lighting illumination intensity of 10 luxs can be adjusted by adjusting 1% duty ratio, before can determining based on this
State mapping relations formula.
S423, judge target duty ratio or target amplitude whether in the predetermined current parameter area of lighting source 20, if
It is to execute step S424, if it is not, executing step S425.
Predetermined current parameter area can be preset according to the electric current that lighting source 20 can be born, due to target area
