LED lighting unit
First Claim
1. A lighting unit comprising:
- a light generating section comprising a plurality of groups of LEDs, each group emitting light of a different spectrum than said other groups, one of said groups including a plurality of LEDs;
a light analysis section that generates an intensity signal related to the intensity of light generated by each of said groups;
a controller that adjusts a current through each of said LEDs in response to said intensity signals;
a housing having a transparent window, said light generation section and said light analysis section being within said housing,a first communication interface that said controller utilizes to communicate with a device external to said lighting unit for receiving commands during the operation of said lighting unit,wherein said light analysis section also generates an ambient intensity signal related to the intensity of light originating from a location outside of said housing.

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.
