Method and apparatus for providing selectively colored light
Abstract:
An apparatus for providing selectively-colored light is disclosed. The apparatus includes a circuit having a plurality of diodes each including an anode and a cathode, wherein the plurality of diodes include a first diode that emits a first light defined by a first wavelength, a second diode that emits a second light defined by a second wavelength, and a third diode that emits a third light defined by a third wavelength, wherein a summation of one or more of the first, second and third light defines a selectively-colored light; and a controller including a first output connected to the anode of the first diode, and the cathode of the second diode, a second output connected to the cathode of the first diode, the anode of the second diode, and the anode of the third diode, and a third output connected to the cathode of the third diode. A method is also disclosed.
