| Title: |
Methods and Apparatus For Controlled Lighting Based on a Reference Gamut |
| Abstract: |
Methods and apparatus for controlled lighting based on a reference color
gamut that is shared amongst multiple lighting units. A reference color
gamut may be determined for multiple lighting units based on spectral
power distributions associated with the lighting units. Variable color
light or variable color temperature white light subsequently may be
generated consistently and predictably amongst multiple lighting units
that are each controlled based on the reference color gamut. Lighting
commands received by multiple lighting units may be appropriately
processed in each lighting unit, based on a predetermined relationship
between the lighting commands and the reference color gamut, to ensure
consistent and predictable color or color temperature reproduction
amongst the multiple units. In one exemplary implementation, the multiple
lighting units include LED light sources to facilitate energy efficient
generation and versatile control of variable color light or variable
color temperature white light, for general purpose illumination and other
applications.
