LIGHT EMITTING DEVICE (LED) LIGHT FIXTURE CONTROL SYSTEMS AND RELATED METHODS
First Claim
1. A light emitting device (LED) lighting system comprising:
- at least one LED configured to emit light at an illumination output level;
at least one light sensor configured to measure the illumination output level of light emitted by the LED; and
a control unit, the control unit configured;
