Luminous Intensity of an LED as a Function of Input …

The voltage across the LED, current through the LED and intensity of the light emitted by the LED were measured. For voltages ranging from 2.4 to 3.5 V, light intensity was found to be linearly related to both the current and the voltage. The input power was found to be directly proportional to the square of light intensity.
