Automatic lamplight controller

Automatic lamplight controller

The utility model relates to an automatic lamplight controller comprising a photosensitive diode (VD), two operational amplifiers (U1 and U2), an emitter follower (T1), a relay (J1), three capacitors (C1, C2 and C3), a diode (D1), and five fixed resistors (R1, R2, R3, R4, and R5). The advantages of...

description The utility model relates to an automatic lamplight controller comprising a photosensitive diode (VD), two operational amplifiers (U1 and U2), an emitter follower (T1), a relay (J1), three capacitors (C1, C2 and C3), a diode (D1), and five fixed resistors (R1, R2, R3, R4, and R5). The advantages of the automatic lamplight controller are as follows: when the power supply for the resident is normal, the lamp is connected to the household electricity with the 220-V voltage and the lamplight is in a normal illumination state; and when the power supply is interrupted, the luminosity is low and the lamp is connected to an auxiliary power supply, so that the lamplight remains in a normal illumination state. Therefore, the one lamp has the two functions and there is no need to additionally configure an emergency light, so that the life becomes simple and convenient.
