This project represents a new locally producible
commercially feasible LED driver circuit which has
low components import and production cost, and
high market value and a relatively long life. This
LED driver is also able to provide as much light and
efficiency as the models available at market right
now. The main task is to design the device for mass
production. So, the team designed the whole device
and other parameters. This poster presents the
method, costing and working principle of the device.

RESULTS
CONCLUSION
Led lighting are gaining more and more attention in
the household and industrial uses. Designing the
whole device, the circuit element like resistance
capacitor inductor value designing. Developing the
working prototype of the pre-elementary circuit. The
future plan of the project is marketing as a product,
increase the watt limit, and design the smart led
driver circuit using sensor. The future expectation of
the project is increasing the efficiency and
sustainability of LED lighting technology. The future
expectation is also that government lose huge amount
of money for production of led driver so in future it is
more low cost as possible.

HARDWARE
1. The circuit can be implemented at lower cost of the
multiple light LED driver. The proposed LED
driver is well suited for use in household LED
lamps. The main advantages of this system are that
it will give high pf for the system and also low
THD. The overall cost is reduced and efficiency is
increased. The main applications come in the field
of lighting which includes street lighting using
LED bulbs and tubes, it can also be used in
architectural lightings consumes less electricity.
The converter gives constant current to the output
so if we vary the load the current and voltage
remain same..
