    Do You Want To save Your Money On Your Electric Bill???? Then This is the project for you. Nowadays We are using CFL bulbs.

CFL vs LED Bulbs

To understand LED light benefits, it’s important to understand the difference between the two bulbs. LED light bulbs produce light when an electrical current passes through them. In CFL bulbs an electric current flows between electrodes at each end of a gas-filled tube. The reaction creates ultraviolet light and heat, which is then changed into light when it hits a phosphor coating on the bulb’s interior. This process takes anywhere from 30 seconds to 3 minutes to complete, according to ENERGY STAR®, which is why it can seem as if your CFL light takes a while to be fully lit.

CFLs used 25-35% less energy than incandescent bulbs, but it you really want to make the biggest environmental impact on the environment, choosing LEDs is the way to go. Residential LEDs, especially those rated by ENERGY STAR, use 75% less energy and last 25 times longer than incandescent lighting. Energy.gov notes that by 2027 widespread use of LEDs could save about 348 TWh of electricity, the equivalent of the annual electrical output of 44 electric power plants (1000 megawatts each). It’s also a total saving of more than $30 billion at today’s electricity prices.

Here are some other differences to keep in mind when examining CFL vs LED bulbs:

  • LEDs emit very little heat. In contrast, incandescent bulbs release 90% of their energy as heat, CFLs release about 80% of their energy as heat, according to Energy.gov.
  • Another LED light benefit is that LEDs because they emit light in a specific direction, do not need diffusers or reflectors that trap lights. This helps increase LED efficiency for users such as downlights (recessed downlights are common in residential kitchens, hallways, and bathrooms) or task lighting.
  • The Department of Energy estimates that there are at least 500 million downlights in U.S. homes, with more than 20 million sold each year. The DOE estimates that both CFL and LED lighting could decrease downlight wattage by at least 75%.
  • The same LED string of holiday lights could still be in use 40 holiday seasons from now, according to Energy.gov.
Parts Required:-

Schematic:-

Procedure:-
  1. First Of All, Connect all the 50 White LEDs in series.
  2. Now Insert 1nF 275V Capacitor in the Vero Board. And Parallelly Connect a 1 Ohm resistor in the Vero Board.
  3.  
  4. Now Connect the Bridge, Which will Convert the AC to DC.
  5. Now Connect a 10M Ohm Resister to the +ve Out out of the Bridge
  6. Now Connect the +ve strand of the 10uf 400V capacitor to the another end of the 10M Ohm Resister
  7. Now Connect the -ve strand of the Capacitor to the -ve Output of the  Bridge.
  8. Now Connect the +Ve pin of the Series LEDs to the +ve strand of the capacitor and -Ve respectively to the -ve strand of the Capacitor
  9. Now connect the 200mA fuse to one of the inputs of 220V AC Power supply in series
  10. Then Finally recheck all the Connection and provide the circuit with 220V power supply.
