1. A method for varying a luminance of a light, comprising:
- setting a target dwell luminance of the light; and
changing the luminance of the light from a current luminance to the target dwell luminance;
whereinthe operation of changing the luminance of the light from the current luminance to the target dwell luminance occurs during a specific time interval of a breathing curve, the breathing curve ramping up or ramping down the luminance of light;
whereinthe target dwell luminance being different from a prior dwell luminance; and
a peak luminance of the breathing curve likewise changes from a first peak luminance value to a second peak luminance value, the first and second peak luminance values having a different luminance.

Abstract
An apparatus and method for controlling the brightness and luminance of a light, such as an LED. The embodiment may vary the brightness and luminance of the LED in a variety of ways to achieve a variety of effects. The exemplary embodiment may vary the rate at which the LED'"'"'s luminance changes, such that an observer perceives the change in the LED'"'"'s brightness to be smooth and linear as a function of time, regardless of the ambient light level. Changes to the LED'"'"'s luminance may be time-constrained and/or constrained by a maximum or minimum rate of change.
