Abstract
A lighting unit having a light generation section, a light analysis section, a controller, and a first communication interface is disclosed. The light generation section and the light analysis section are housed in a housing having a transparent window. The light generating section includes a plurality of groups of LEDs, each group emitting light of a different spectrum than the other groups. The light analysis section generates intensity signals related to the intensity of light generated by each of the groups and the intensity of light originating from a location outside the housing. The controller adjusts a current through each of the LEDs in response to the intensity signals. The first communication interface is utilized by the controller to communicate with a device external to the lighting unit for receiving commands during the operation of the lighting unit.
