Parameters
brightnessThe input intensity, from 0.0-1.0, to convert
Returns
The CIE 1976 relative luminance, normalized to a 0-1 scale

"Brightness" is perception oriented for intuitiveness. This function can be used to convert the perceptual value to a normalized luminance value that an LED driver can use to determine the correct PWM duty cycle or analog current drive strength needed to produce the associated brightness.
