  If I recall properly, the semiconducting material used in the LED determines the color of the LED. Not entirely sure about whether current has any influence on it; logically, it shouldn't.

  There are two main types of LED, AlGaInP ( red, orange and yellow )and InGaN ( white, green and blue). Changing these composition, LED color can be changed

  You have sharp Memory ! Yeah Light Emission from LED is depend on the Material used in LED and intensity is depend on the current passes through LED.

  Cool. I'm being driven away from my roots 😒. Yes, the intensity would clearly depend on the amperes passing through. It'd however be interesting if the current could factor in determining the color of LED. What say? 😀

  Color which is visible to us from LED is depend on the energy radiated by electron when it comes back to stable orbit. And Unstable Orbit may change based on the silicon material used in LED so Light emission is depend on the difference between Unstable Orbit and Stable Orbit.

  Hi,
  
  please tell me how the intensity of an led is dependent on the current passing through it
