LED lighting system
First Claim
1. A system to generate artificial sunlight with spectral characteristics that resemble natural sunlight, the system comprising:
- a computing device communicatively coupled to a plurality of lighting elements operable to emit white light in a range or color temperatures between 1800K and 6500K, wherein the computing device is operable to;
present a graphical user interface panel which represents a floor plan and a respective spatial position of each of a number of lighting fixtures relative to the floor plan;
receive user-selected input that specifies an enclosed shape on the floor plan which encompasses at least one of the lighting fixtures to select the lighting fixtures encompassed by the enclosed shape; and
cause at least one of the plurality of lighting elements corresponding to the at least one lighting fixture encompassed by the enclosed shape to emit the white light in the range of color temperatures.

Abstract
A system and method involving lighting fixtures, a control network, a controller and other devices such as light sensors, input devices and network adapters for coordinating precise brightness and color schedules among the lighting fixtures while maintaining a high color reliability including provisions for managing a plurality of lighting fixtures. The lighting fixtures contain lighting elements selected such that when controlled properly, operating along a daytime locus, the resultant light output closely resembles sunlight on a cloudless day in spectral characteristics, and wherein the total flux of blue light can be adjusted from a relative level of 1-100% the maximum blue flux of the lighting fixture by controlling individual lighting elements.
