Abstract :
Growing demand for the saving of
electricity.
Failure in power supply causes
difficulty and inconvenience.
An automatic emergency lamp that uses
LED .
Highly bright due to use of white LEDs.
Turns on when mains supply fails ,turns off when power resumes.
Has own battery charger –stops charging
automatically when fully charged.
This project aims to develop most power
efficient and user friendly product.
FUTURE SCOPE
We can again modernize this project using PWM.
It is expected that with additional
development and growing researches, the PWM will gain more popularity and the
cost of these
bulbs will eventually decline.
This project can be adopted for mass
production as cheap and efficient method.
The project was concluded to be
innovative for the improvement of day today life.
Device also adds a new look to the
traditional lamps.
The use of PWM helps us to reduce the
wastage of energy.
The cost of implementing this circuit
is also very less - an added advantage in using this circuit.
