Abstract

The present invention discloses an over-current protection buffering-type emergency lamp circuit. The circuit comprises a constant current source circuit, a diode rectifier U, an operational amplifierP1, a triode VT1, a triode VT2, a triode VT3, a battery GB, a emergency lamp BL, a switch KA, a capacitor C1, a capacitor C2, a capacitor C3, a capacitor C4, a resistor R1, a resistor R2, a resistorR3, a resistor R4, a resistor R5, a resistor R6, a sliding rheostat RP, a zener diode D1, a diode D2 and a diode D3. The circuit has the advantages of simple structure, low cost and convenience for maintenance. The structure design of the circuit is reasonable, when urban power supply can be used normally, the urban power supply charges the battery GB, and when the urban power supply is cut off, the battery GB can supply power, so that the emergency lamp BL is lighted automatically, i.e., the emergency lamp BL can perform emergency lighting. The circuit is suitable for popularization and application.

Description

technical field [0001] The invention relates to an overcurrent protection buffer type emergency light circuit. Background technique [0002] Emergency light is a device that can be illuminated after the normal power supply is cut off or the power is cut off due to fire accidents. Although emergency lights are not often used, they are essential in modern buildings. At present, domestic power supply is relatively sufficient, and emergency lights are rarely used. Therefore, regular inspection and maintenance of emergency lights is required to ensure that emergency lights can be used normally. At present, the structure of the control circuit used for emergency lights is relatively complicated, and many electronic components are used, which makes the cost of the control circuit relatively high, and is not easy to maintain and repair. Contents of the invention [0003] The purpose of the present invention is to provide an overcurrent protection buffer type emergency light circu...
