| Title: |
Systems and Methods of Controlling the Output of a Light Fixture |
| Abstract: |
Systems and methods of controlling the output of an LED light fixture.
The LED light fixture includes a plurality of light sources and a
controller. The controller is configured to receive a first set of input
data and determine a difference between the first set of input data and a
second set of data stored in memory. The controller is also configured to
set a slew time based on the determined difference and control the output
of the light fixture based on the slew time. The slew time is inversely
related to the determined difference between the first set of input data
and the second set of data, and the slew time corresponds to the amount
of time that the output of the light fixture is to take to transition
from a present output of the light fixture to a new output of the light
fixture.
