    Abstract: Semiconductor light emitting devices are provided that include a first string of light emitting diodes (“LED”) that emit unsaturated light having a color point that is within at least eight MacAdam ellipses of one or more points within a first blue-shifted-yellow region on the 1931 CIE Chromaticity Diagram, a second string of LEDs that emit unsaturated light having color point that is within at least eight MacAdam ellipses from one or more points within a second blue-shifted-green region on the 1931 CIE Chromaticity Diagram, and a third light source that emits radiation having a dominant wavelength between 600 and 720 nm. A drive circuit is provided that is configured to supply a first drive current to the first string of LEDs, a second drive current to the second string of LEDs and a third drive current to the third string of LEDs, wherein at least two of the first, second and third drive currents are independently controllable.

    Abstract: A lighting fixture with a control system, a light source, and an image sensor is disclosed. The image sensor is configured to capture an image in response to an image capture signal. The light source emits light in response to a drive signal. The control system provides the drive signal to control the light emitted by the light source, and when an image needs to be captured, provides the image capture signal. When capturing an image, the control system may coordinate the drive signal and the image capture signal so that the image sensor captures the image when the light source is emitting light, if light is needed or desired. The control system may control the drive signal to control the light emitted by the light source or control other lighting fixtures in the lighting network based, at least in part, on information derived from one or more captured images.
