Photoresistor Light Control of The Boost Circuit Diagram
As shown in the light-control step-up circuit. The circuit is commonly used in emergency automatic lighting. When sudden power blackout, light dependent resistor RL will be loss of light illumination and high-impedance state, 2 feet in low the  TWH8751  integrated circuits, consisting of TWH8751 such as oscillation circuit, 4 pin output a series of pulse current boost by the transformer T, lit fluorescent tubes EL automatic lighting outage.
