When light gone its automatically on and when light comes it will off and charge your battery slowly 100ma. Ultra bright white led consumes 3v and 20ma current. Fully automatic emergency light circuit diagram when mains power is available reset pin 4 of ic 555 is grounded via transistor t4.

We have used four bright white leds more leds can be added to produce more light considering that total current consumption should not exceed the supply current. When mains fails transistor t4 does not conduct and reset pin 4 gets positive supply though resistor r3. Working of automatic emergency light circuit.
