Specific embodiment
The present invention will be further explained below with reference to the attached drawings:
The present invention includes display backlight EL, switch SA, first resistor R1 to 3rd resistor R3, first as shown in Figure 1:
Potentiometer RP1, the second potentiometer RP2, bidirectional triode thyristor SCR, bilateral diode VD, capacitor C and photo resistance RG, the switch
The first end of SA is connect with the first end of AC power source AC, and the one of the second end of the switch SA and the display backlight EL
End connection, the second end of the display backlight EL simultaneously with the first end of bidirectional triode thyristor SCR, the first potentiometer RP1
First end is connected with the sliding end of the first potentiometer RP1, the other end of AC power source AC simultaneously with bidirectional triode thyristor SCR second
It holds, the first end of capacitor C is connected with the first end of photo resistance RG, the control terminal and bilateral diode VD of bidirectional triode thyristor SCR
First end connection, the second end of bilateral diode VD connect with the first end of first resistor R1, the second end of first resistor R1
It is connect simultaneously with the second end of the first end of second resistance R2, the first end of 3rd resistor R3 and capacitor C, the of second resistance R2
Two ends are connect with the second end of the first potentiometer RP1, the second end of 3rd resistor R3 while the first end with the second potentiometer RP2
It is connected with sliding end, the second end of second resistance R2 is connect with the second end of photo resistance RG.
Preferably, the first resistor R1 is 3.3k Ω, the second resistance R2 is 15k Ω, the 3rd resistor R3
For for 3.6k Ω, the first potentiometer RP1 and the second potentiometer RP2 be 10k Ω, bidirectional triode thyristor type SCR be MCR100-6,

Working principle of the present invention is as follows:
The present invention uses rc phase shifter circuit, but the charging rate of capacitor C is also related with shunt circuit.In 3rd resistor
In the case that R3, the second potentiometer RP2 are fixed, the size of shunting is determined by the resistance value of photo resistance RG.When ambient light is bright
Degree increases, and photo resistance RG resistance value becomes smaller, and shunts and increases, and capacitor C both end voltage rises slack-off, the bidirectional triode thyristor SCR angle of flow
Reduce, output voltage reduces, display backlight EL brightness decline；Conversely, when network voltage decline, photo resistance RG resistance value
Increase, shunt and reduce, the bidirectional triode thyristor SCR angle of flow increases, and output voltage increases, and display backlight EL brightness increases.This
Sample, display backlight EL brightness is just automatically stable (to be determined) in setting value by the first potentiometer RP1.
