    Abstract: An LED light fixture comprising a plurality of LEDs mounted on a substrate, wherein the plurality of LEDs include a lime/mint light source accounting for at least 25% of the total lumen output, and a deep red light source accounting for at least 0.5% of total lumen output. The lime/mint light source preferably accounts for at least 50% of the total lumen output. The deep red light source preferably accounts for at least 1.0% of the total lumen output. The light fixture can also include other colors, such as 1% to 50% cyan, 1% to 20% red/red-orange, and 1% to 10% blue/indigo. In one embodiment, the fixture further includes a processor for calculating a color mix and driving the LEDs. Preferably, the processor is programmed to produce a color mix having a CCT in the range of 2700-6500K, a TM-30 (Rf) of at least 90, and a TLCI of at least 95.

    Abstract: A light fixture including an array of LED light sources corresponding to a color channel of the light fixture, a driver circuit configured to drive the array of LED light sources, and a controller. The controller controls the operation of the light fixture to receive a direct drive signal related to a direct drive signal value for the array of LED light sources, determine an output of a reference light fixture based on the direct drive signal, determine a value for a color channel drive signal based on the output of the reference light fixture, and provide a control signal to the driver circuit to cause the driver circuit to apply the color channel drive signal having the value to the array of LED light sources. The value for the color channel drive signal results in an output of the light fixture that matches the output of the reference light fixture.

    Abstract: A method of controlling a plurality of light fixtures. The method includes detecting the light outputs of a plurality of light fixtures and detecting a reflection of light from a surface. The light outputs and the reflection of light are analyzed. Differences among the light outputs of the plurality of light fixtures are determined, and a difference between the reflection of light and a desired reflection of light is determined. New or updated values for output color, output brightness, and output spectra are determined for the plurality of light fixtures such that the light outputs of the light fixtures are consistent and correspond to a desired light output, and such that the reflection of light corresponds to the desired reflection of light. Each of the plurality of light fixtures is then driven using respective light source output values to produce the desired light outputs.
