Current-limiting resistance R4 one end, resistance R1 one end other end electrical connection photo resistance PR other ends, integrated operatinoal amplifier IC1 input positive poles
End, integrated operatinoal amplifier IC1 input cathode end electrically connect with variable resistance RW sliding end, and integrated operatinoal amplifier IC1's is defeated
Go out end to electrically connect with the negative pole end of IC2 input positive terminal, reset switch K one end and feedback diode D1, integrated operatinoal amplifier IC2
Input negative pole end electrically connected with divider resistance R2 one end, divider resistance R3 one end, integrated operatinoal amplifier IC2 output end with it is luminous
Diode D2 positive terminals and feedback diode D1 positive terminal electrically connect, and light emitting diode D2 negative pole end passes through resistance R4 and electricity
Source V1 negative pole ground wire connection.
The invention has the advantages that the characteristic using photo resistance --- light is darker, and resistance is bigger, using it to light
The high sensitivity of line and design.When ambient light is dimmed for some reason, this inductor can sense generation high pressure, so as to
Make lumination of light emitting diode.As long as light and shade change occurs for ambient light, light-inductive resistance will be sensed, defeated so as to influence
Go out, if external lighting circuit, the present invention can when when dim the automatic start light emitting diode or electrical equipment, meet
Needs of the user to light.If external electrical equipment is circuit for alarming, it can be sounded the alarm when dim and remind user's note
Meaning.
