Three-dimensional plant growth lighting system

A three-dimensional (3D) plant growth lighting system, comprising:

• a top lighting module disposed on a top of a plant chamber,
• wherein the plant chamber contains a plant;
• a lateral lighting module disposed on one side of the plant chamber;
• a bottom lighting module disposed on a bottom of the plant chamber;
• a controller connected to the top lighting module, the lateral lighting module and the bottom lighting module so as to control the top lighting module, the lateral lighting module and the bottom lighting module;
• a database connected to the controller and configured to save a plurality of light formulas corresponding to a plurality of plant species respectively;
• a carbon dioxide module connected to the controller, and comprising a carbon dioxide generator and a carbon dioxide sensor configured to detect a carbon dioxide concentration of the plant chamber and generate a carbon dioxide concentration signal;
• an illuminance sensor connected to the controller and configured to detect an illuminance of the plant chamber in order to generate an illuminance signal;
• and
• a spectrum sensor connected to the controller and configured to detect a spectrum of a light in the plant chamber so as to generate a spectrum signal;
• wherein the controller is configured to download the light formula corresponding to the plant from the database, and compare the light formula with the carbon dioxide concentration signal, the illuminance signal and the spectrum signal to generate an intelligent control signal so as to control one or more of the carbon dioxide generator, the top lighting module, the lateral lighting module and the bottom lighting module.
