DustAD_L1=DustAD_D1-DustAD_E1；
DustAD_L2=DustAD_D2-DustAD_E2；
……
DustAD_Ln=DustAD_Dn-DustAD_En.

DustAD_L=(DustAD_L1+DustAD_L2+ ...+DustAD_Ln)/n.
Afterwards, according to the first average value DustAD_L for calculating gained, the current laying dust situation of screen pack is judged, it is determined that
Whether filter screen is current dirty stifled.Alternatively, the step S31 includes：
Step c, if first average value is less than first predetermined threshold value, it is determined that the screen pack is current dirty stifled；
Step d, if first average value is more than or equal to first predetermined threshold value, it is determined that the screen pack is current
It is not dirty stifled.
Alternatively, after the first average value DustAD_L of acquisition is calculated, by the first average value DustAD_L and first
Predetermined threshold value is compared.If first average value DustAD_L is less than the first predetermined threshold value, illustrate that opening and closing are luminous
The testing result difference of pipe is little, illustrates that the current laying dust of screen pack is more, namely screen pack is current dirty stifled.If this is first average
Value DustAD_L is more than or equal to the first predetermined threshold value, then the testing result difference of explanation opening and closing luminous tube is larger, says
The current laying dust of bright screen pack is few, namely screen pack is current also not dirty stifled.
The scheme that the present embodiment provides, close in luminous tube respectively by circulating to perform and screen pack is entered under opening
Row laying dust detect, multigroup first detected value and the second detected value corresponding to acquisition, and calculate respectively each group of the first detected value and
The difference of second detected value, the first average value of multigroup difference is calculated, then according to the first average value, determine that screen pack is currently
It is no dirty stifled.Determine whether screen pack is current dirty stifled, therefore, enters one by then passing through multigroup first detected value and the second detected value

Step S53, when second average value is less than the second predetermined threshold value, calculate the first average value of multigroup difference.
In the present embodiment, the difference DustAD_L1 of the detected value of each group first and the second detected value is being calculated respectively,
After DustAD_L2 ... ... DustAD_Ln, according to putting in order for each group difference, the change between adjacent two difference is calculated successively
Change value.For example, the changing value DustAD_W1=DustAD_L2- between calculating difference DustAD_L2 and difference DustAD_L1
DustAD_L1, the changing value DustAD_W2=DustAD_L4- between difference DustAD_L4 and difference DustAD_L3
DustAD_L3；... the changing value DustAD_Wm=DustAD_Ln- between difference DustAD_Ln and difference DustAD_Ln-1
DustAD_Ln-1, wherein, m=n/2.
It is understood that the changing value between adjacent two difference can also be calculated by other means, for example, successively
Calculating each changing value is：
DustAD_W1=DustAD_L2-DustAD_L1, DustAD_W2=DustAD_L3-DustAD_L2 ... ...
DustAD_Wn-1=DustAD_Ln-DustAD_Ln-1.
Changing value DustAD_W1, DustAD_W2 ... ... DustAD_Wm between each adjacent two difference is calculated it
Afterwards, then the average value of this multiple changing value is calculated, for the ease of description, it is flat that the average value of multiple changing values is hereafter referred to as second
Average DustAD_W.Therefore, the second average value DustAD_W, which is calculated, is：
DustAD_W=(DustAD_W1+DustAD_W2+ ...+DustAD_Wm)/m.
In the present embodiment, the threshold value fluctuated for judging ambient light whether to occur is also previously provided with, for the ease of describing,
The threshold value is hereafter referred to as the second predetermined threshold value.After the second average value DustAD_W of multiple changing values is calculated, by
Two average value DustAD_W are compared with the second predetermined threshold value.If the second average value DustAD_W is less than the second predetermined threshold value,
Then illustrate that ambient light does not fluctuate, or ambient light is fluctuated in allowable range, now, just according to each group difference
DustAD_L1, DustAD_L2 ... ... DustAD_Ln, the first average value DustAD_L is calculated.And according to the first average value
DustAD_L, determine whether screen pack is current dirty stifled.Specifically determination process is as described in the second embodiment, just no longer superfluous herein

Further, after by the second average value DustAD_W compared with the second predetermined threshold value, if the second average value
DustAD_W is more than or equal to the second predetermined threshold value, then illustrates that ambient light fluctuates, namely current environment and unstable, this
When, laying dust detection is carried out to screen pack again.Specifically, it is right under luminous tube closing and opening respectively to continue cycling through execution
Screen pack carries out laying dust detection, the operation of multigroup first detected value and the second detected value corresponding to acquisition, so as to which basis obtains again
Multigroup first detected value and the second detected value taken, is calculated the second new average value DustAD_W.If recalculate to obtain
The second average value DustAD_W be less than the second predetermined threshold value, illustrate that current environment is stable, now, then to be calculated first average
