Patent ID: 8632208

Claim:
A methodology for creating lighting of white color with an intended correlated color temperature (CCT), comprising the steps of: providing a lamp system, wherein the lamp system includes a lighting system; wherein the lighting system comprises four lighting means groups, wherein the four lighting means groups comprise: a first lighting means group comprising a plurality of amber light-emitting diodes (LED) with a dominant wavelength in the range of 585 nm to 595 nm; a second lighting means group comprising a plurality of phosphor-based warm white LED having a CCT in the range of 2500K to 3700K; a third lighting means group comprising a plurality of phosphor-based white LED having a CCT in the range of 3700K to 5000K; a fourth lighting means group comprising a plurality of phosphor-based cool white LED having a CCT in the range of 5000K to 7000K; and providing a processing means selectively operable to instruct the lighting system to change the lighting to the intended CCT; wherein the processing means is selectively operable to vary a brightness level of lighting system; wherein the processing means is selectively operable to select a combination of the first lighting means group and only two of the second through fourth lighting means groups to provide lighting of a fixed CCT.
