LED mV / mcd function


I am using the SSL-LX5093HD LEDs for a project and was hoping to find a function that describes the relationship between mV input and mcd output. I looked on the product data sheet and was able to find a ‘maximum’ mcd, but no other information. Please help!!



Optical output from an LED is, to a first approximation, directly proportional to drive current. Halve the drive current, get half the intensity.

The relationship between applied voltage and optical output is not nearly as neat; it’s very non-linear for one thing, and it also shifts somewhat with temperature.
