General Description
The MXJDJ822 is an optical feedback controller for LED based
lighting systems. These systems typically consist of red, green
and blue LED’s, LED drivers, a tri-color photosensor, and the
MXJDJ822 feedback controller.
The MXJDJ822 processes color information from the
phototsensor and adjusts the red, green and blue LED drivers
to achieve the desired color. Through the feedback control of the
MXJDJ822 an LED array will maintain its color over time and
temperature.
The desired color from the light output of the LED array is user
programmable by simply writing the color coordinates from the
CIE color space into the MXJDJ822 through the I
interface.
The LED drivers are controlled by PWM signals from the
MXJDJ822. These signals determine the on-time durations of
the red, green and blue LED’s. On-time durations are
continuously adjusted in real-time to match the light output of the
LED array to the desired color programmed into the MXJDJ822.
