Abstract

See full text

A system allows a light fixture to have a wider range of color temperatures (CCT) while limiting the warmest temperature reached at full intensity. The CCT of the light output may be controlled independently of intensity across a certain range of CCT and dependent on intensity across another range. In an implementation, both intensity and CCT may be adjusted from a single handle, where the interface positions may be divided into multiple zones. In another implementation, intensity may be adjusted from a first handle, while CCT may be adjusted from a second handle. The CCT of the light output may be limited to cooler levels when the intensity is higher, and/or the intensity of the light may be limited to lower levels when the CCT is warmer.
