Principle : It is based on photovoltaic effect (generation of voltage due to bombardment of light photons). When solar cell is illuminated with light photons of energy (h ν) greater than the energy gap (E g ) of the semiconductor , then electron-hole pairs are generated due to absorption of photons.Get a Quote
If ambient light dims, transistor T1 turns on to drive the triac T2. Now the lamp load at the output of T2 energises. When the ambient light level restores, circuit returns to its idle state and light(s) switched off by the circuit. Working voltage for the circuit is derived directly from the AC supply input through components R1, R2 and R3.
