Abstract

A method may comprise: commanding, by a processor, a lighting system to generate a first desired effect in accordance with a first spectral weighting mode; determining, by the processor, a first optimized predetermined variable within a first predetermined domain to generate the desired effect based on the first spectral weighting mode; commanding, by the processor, the lighting system to transition from the first desired effect to a second desired effect, the second desired effect in accordance with a second spectral weighting mode; and determining by the processor, a second optimized predetermined variable within a second predetermined domain to generate the second desired effect based on the second spectral weighting mode, the first optimized predetermined variable being different from the second optimized predetermined variable.

First claim

What is claimed is:

1. An article of manufacture including a tangible, non-transitory computer-readable storage medium having instructions stored thereon that, in response to execution by a processor, cause the processor to perform operations comprising:
command, by the processor, a lighting system to generate a first desired effect in accordance with a first spectral weighting mode;
determine, by the processor, a first optimized predetermined variable within a first predetermined domain to generate the first desired effect based on the first spectral weighting mode;
command, by the processor, the lighting system to transition from the first desired effect to a second desired effect, the second desired effect in accordance with a second spectral weighting mode; and
determine by the processor, a second optimized predetermined variable within a second predetermined domain to generate the second desired effect based on the second spectral weighting mode, the first optimized predetermined variable being different from the second optimized predetermined variable.

2. The article of manufacture of claim 1 , wherein the second predetermined domain is different from the first predetermined domain.

3. The article of manufacture of claim 1 , wherein the first predetermined domain is chromacity coordinates, and wherein the second predetermined domain is color temperature brightness.

4. The article of manufacture of claim 1 , wherein the operations further comprise:
command, by the processor, the lighting system to transition from the second desired effect to a third desired effect, the third desired effect in accordance with a third spectral weighting mode; and
determine by the processor, a third optimized predetermined variable within a third predetermined domain to generate the third desired effect based on the third spectral weighting mode.

5. The article of manufacture of claim 4 , wherein the third optimized predetermined variable is different from the second optimized predetermined variable and the first optimized predetermined variable.

6. The article of manufacture of claim 4 , wherein the first predetermined domain, the second predetermined domain, and the third predetermined domain are all different.

7. The article of manufacture of claim 6 , wherein the first predetermined domain is chromacity coordinates, wherein the second predetermined domain is color temperature brightness, and wherein the third predetermined domain is color brightness.

8. A lighting system, comprising:
a plurality of light emitting diodes (LEDs); and
a controller in operable communication with the plurality of LEDs, the controller configured to transit the plurality of LEDs from a first spectral weighting mode to a second spectral weighting mode, the first spectral weighting mode configured to optimize a first variable of the lighting system over a first predetermined domain, the second spectral weighting mode configured to optimize a second variable of the lighting system over a second predetermined domain, the first predetermined domain being different from the second predetermined domain, the first spectral weighting mode corresponding to a first desired effect, the second spectral weighting mode corresponding to a second desired effect.

9. The lighting system of claim 8 , wherein the plurality of LEDs comprise at least five LEDs.

10. The lighting system of claim 8 , wherein the plurality of LEDs comprise at least six LEDs.

11. The lighting system of claim 8 , wherein a first LED of the plurality of LEDs is configured to emit electromagnetic radiation having a first wavelength of between 490 nm and 510 nm and generate a cyan color.

12. The lighting system of claim 11 , wherein the first variable is an intensity of the first LED and the first desired effect is wakefulness.

13. The lighting system of claim 11 , wherein the first variable is maximized to achieve the first desired effect.

14. The lighting system of claim 8 , wherein each LED in the plurality of LEDs is configured to emit an electromagnetic radiation having a wavelength, the wavelength being different for each LED in the plurality of LEDs.
