LIGHT EMITTING DIODE CHARACTERISTICS

E4

 

Objectives

  • To demonstrate the operation of a typical visible light emitting diode (green & yellow coloured), after drawing a "forward current versus forward voltage" characteristics curve of an LED.
  •  To select the current limiting resistance of an LED, and to verify that the LED has higher reverse resistance, just like NPN junction diode when LED is reverse biased
  • To demonstrate the difference in LED radiation patterns of color LED
