Reality in LED Bulbs. Home Utility Circuit. 25

3AWe all use LED Bulbs to save energy. It is available in 3W, 5W,7W,9W,15,18W etc . What this Watt indicates? Is its Power output similar to CFL, Tube light etc or light intensity similar to CFL or Tube light? If you consider the specified watts as the real output, then it is a mistake because the Capacitor power supply used in LED bulbs cannot give the specified output. For example, a 9 Watt LED bulb shows that it is only 3.9 W both in theoretical calculation and in power measurements. Let us hack one LED Bulb to see how it is behaving.

LED Bulb Hacked. Home Utility Circuit 8

LED-BULBWe all use LED bulbs today to save energy. Different types of LED bulbs ranging from 3 Watts to 15 Watts are now available at low cost. The LED bulb has an array of serially connected 0.5 watt Chip LEDs and a small capacitor power supply. We can also easily make the LED bulb. Let us see what is inside the LED bulb and the circuit operating it.
