Lighting system for indoor grow application and lighting fixtures thereof

A lighting system for an indoor grow facility, the lighting system comprising:

• a main controller that is configured to generate an analog control signal and a digital control signal;
• and
• a light fixture comprising:
• a plurality of LED lights;
• an LED driver circuit electrically coupled with the plurality of LED lights;
• and
• a controller in signal communication with the LED driver circuit and configured to transmit a driver signal to the LED driver circuit for controlling operation of the plurality of LED lights, the controller comprising:
• a digital communication module in signal communication with the main controller for receiving the digital control signal and configured to transmit the digital control signal to a downstream light fixture;
• and
• an analog communication module in signal communication with the main controller for receiving the analog control signal simultaneously with the digital control signal and configured to transmit the analog control signal to the downstream light fixture, wherein:
• the controller of the light fixture is configured to determine whether a failure condition exists for the digital control signal;
• when the failure condition does not exist, the controller of the light fixture converts the digital control signal into the driver signal;
• and
• when the failure condition exists, the controller of the light fixture converts the analog control signal into the driver signal.

A light fixture for an indoor grow facility, the light fixture comprising:

• a plurality of LED lights;
• an LED driver circuit electrically coupled with the plurality of LED lights;
• and
• a controller in signal communication with the LED driver circuit and configured to transmit a driver signal to the LED driver circuit for controlling operation of the plurality of LED lights, the controller comprising a conversion module that is configured to receive an original control signal from a remote source and generate a secondary analog control signal and a secondary digital control signal from the original control signal for transmission to a downstream electronic device.
