If reducing ratio or default scaling up, it is also possible to be different, such as in object illumination value and default illumination
When scope difference is bigger, being adapted to property improves presets reduction ratio or default scaling up so that target is shone
Angle value can be positioned at default illumination range faster.
In this utility model embodiment, preset reduction ratio and default scaling up is all 10.
S863, according to electric current adjustable strategies, adjust the power supply current value of luminescence unit 20.
As a example by object illumination value is more than presetting illumination range, can be by the power supply current value of luminescence unit 20
Lower 10.
S864, the light illumination value of detection target area, as object illumination value.
After illuminance transducer records object illumination value, this object illumination value is added to illumination data storehouse,
Now, should sequentially be arranged with two object illumination values in illumination data storehouse, the two numerical value is different.
S865, poor with the illumination of previous object illumination value according to object illumination value, object illumination value is corresponding
The difference between current and presetting of the power supply current value power supply current value corresponding with previous object illumination value shine
Degree scope, determines target current value.
Owing to controller 40 has the object illumination value obtained from target area in order, then perform step S54
Time, previous object illumination value can be determined, and then the illumination obtaining the two is poor in the way of inverted order.
In this utility model embodiment, power supply current value corresponding for object illumination value and previous target are shone
The electric current value difference of the power supply current value that angle value is corresponding, object illumination value and the illumination of previous object illumination value
The product of the default brightness value in the inverse of difference and default illumination range, as target current value.
Default brightness value can be to preset any one brightness value in illumination range, such as, can be intermediate value.
Object illumination value measured by step S861 be target area record first time, target in step S865
The current value of the power supply current value that power supply current value that brightness value is corresponding is corresponding with previous object illumination value
Difference can obtain according to illumination data storehouse, it is also possible to obtains according to electric current adjustable strategies.
As a example by still in electric current adjustable strategies, default reduction ratio and default scaling up are all 10, electricity
Stream adjustment amplitude is power supply current value at the current value changed through overcurrent adjustable strategies, such as, and power supply
Current value is 1 ampere, and after adjusting through default scaling up, it is 1 ampere that its electric current adjusts amplitude
* 10%=0.1 ampere.
It should be noted that when measured by step S861, object illumination value nontarget area record first,
The power supply that the power supply current value that in step S865, object illumination value is corresponding is corresponding with previous object illumination value
The electric current value difference of current value can obtain according to illumination data storehouse, does not repeats at this.
S866, the power supply current value of luminescence unit 20 is adjusted to target current value, and returns step S82.
In this utility model embodiment, controller 40 can adjust speed with predetermined current, by luminescence unit
Power supply current value be adjusted to target current value.
It is not too large that predetermined current adjusts speed so that the sent luminous flux of luminescence unit 20 will not suddenly change,
Avoid the luminous flux sudden change injury to people's eyes.
Concrete, it is right that predetermined current adjustment speed can pass through pid algorithm (proportional-integral-differential algorithm)
Target current value does computing, does not repeats at this.
Owing to the illumination recording twice light illumination value of needs of target current value is poor, sentenced by step S861
Whether disconnected object illumination value is recording first of target area, is in target area 200 in object illumination value
When recording first, in addition it is also necessary to determine Next object illumination value by step S862 to S864, with this two
The illumination difference of individual object illumination value just can obtain target current value.
Otherwise, fail to adjust to default photograph light illumination value in target area if performing step S86
In the range of degree, during follow-up each execution step S86, object illumination value is not that target area records first.
Now, the target that controller 40 once measures before obtaining in the illumination data storehouse of storage object illumination value
Brightness value, is worth to illumination with the two object illumination poor, and then utilizes step S86 to obtain target current value.
In this utility model embodiment, means of illumination passes through controller 40 by the supply current of luminescence unit 20
After value is adjusted to target current value, again detected the light illumination value in target area, root by step S82
According to the light illumination value newly recorded as object illumination value.It is further continued for performing step S84, if step S84
The object illumination value that interior judgement newly records meets default illumination range, then show that step S86 is for supply current
The adjustment of value has made the light illumination value in target area meet default illumination range.Otherwise, if step
The object illumination value that in rapid S84, judgement newly records does not meets default illumination range, then can be with new object illumination
Value performs step S86 again.
Do transit node by the judged result of step S84, do not meet default illumination range in object illumination value
Time, continuous repeated execution of steps S86 of meeting so that object illumination value is constantly close presets illumination range, until
When object illumination value is in default illumination range, then perform step S88.
S88, control illuminator are in preset duration internal radiation target area 200.
Wherein, preset duration can be pre-stored among controller 40, when lighting demand is stronger, permissible
Setting preset duration as a biggest numerical value, such as 1,000 hours, now luminescence unit 20 can be managed
Solve as irradiating target area 200 always, until user removes manual-lock illuminator.Certainly, lighting demand
Time more weak, preset duration can be set as a rational numerical value, such as two hours, under this duration,
People also will not feel tired with eye, well protects people healthy with eye.The most irradiated at luminescence unit
After preset duration, point out user also by specific light efficiency, voice or the mode such as automatically turn off the light.
Means of illumination that embodiment of the present utility model is provided and illuminator, be in pass by luminescence unit
