Introduction :
Now-a-days compact fluorescent lamps (CFL) are becoming very popular as they consume
very little power but provide much higher brightness than the ordinary bulbs. 11-watt CFL
is equivalent to 75-watt bulb in terms of light output. The circuit presented here is
capable of lighting up a 9 to 11-watt CFL. The circuit is automatically switched on when the
AC mains supply fails. Dynatek make 11 watt Emergency Light circuit is very compact,
efficient operating on very low voltage. It operates on 4 x 4 Ahr NICD
( 4.8 VDC) / Lead acid 6V,4 Ahr for 2.5 Hrs continuous after mains fail. NICD battery
charges through constant current source. Microcontroller based Real time clock is
provided to "Switch On / Off" emergency light at set time only, this feature avoids
battery discharge during unwanted time when mains fail. It's rugged design and high
reliability makes it particularly suitable for industrial applications.
