Abstract: The present disclosure provides lighting systems, which may be semiconductor light emitting devices, with two or more of blue, red and/or LRNE, short-blue-pumped cyan, long-blue-pumped cyan, yellow, and violet channels. The lighting systems can have a plurality of operational modes that provide different biological effects while having good color rendering capability. The yellow and violet channels can include violet LEDs and be used in operational modes that provide white light with lower EML values relative to operational modes using three or more of the blue, red, short-blue-pumped cyan, and long-blue-pumped cyan color channels.

Abstract: A platform for design of a lighting installation generally includes an automated search engine for retrieving and storing a plurality of lighting objects in a lighting object library and a lighting design environment providing a visual representation of a lighting space containing lighting space objects and lighting objects. The visual representation is based on properties of the lighting space objects and lighting objects obtained from the lighting object library. A plurality of aesthetic filters is configured to permit a designer in a design environment to adjust parameters of the plurality of lighting objects handled in the design environment to provide a desired collective lighting effect using the plurality of lighting objects.

Abstract: The present disclosure provides systems for generating tunable white light. The systems include a plurality of LED strings that generate light with color points that fall within red, blue, green, and cyan color ranges, with each LED string being driven with a separately controllable drive current in order to tune the generated light output. Methods of generating white light by combining light generated by red, blue, green, and cyan color channels. Methods of generating white light points at substantially the same 1931 CIE chromaticity diagram color coordinates having different EML.

Abstract: Lighting system including visible-light source, optical system, mounting system, and control system. Visible-light source includes plurality of semiconductor light-emitting devices (SLEDs) and selectably generates: visible-light emissions having cyan-ish color point; and visible-light emissions having orange-ish color point. Optical system and mounting system are integrated with visible-light source.
