Abstract:
1. A system for automatically adjusting light intensity of a lighting fixture having a plurality of emitters, said system comprising: a power supply for supplying at least one current source to said plurality of emitters; at least one first emitter capable of emitting light of a first wavelength; at least one second emitter capable of emitting light of a second wavelength; and a control circuit for increasing share of a first current distributed from a feeding current of said at least one current source through said at least one first emitter and decreasing share of a second current distributed from said feeding current of said at least one current source through said at least one second emitter, wherein said control circuit comprises an inlet port and an outlet port, said control circuit being connected to said at least one current source at said inlet port to receive said feeding current, and said outlet port of said control circuit being connected to said interconnecting point of said at least one first emitter and at least one second emitter, wherein said control circuit comprises: wherein said plurality of emitters collectively emit light at a predefined variable light-intensity depending upon at least one level of a feeding current supplied by said at least one current source.
