Abstract
The invention provides a three-channel lighting apparatus with the option to support the human circadian rhythm. By choosing especially the blue LED and green phosphor, the range of biological activity that can be changed is optimized. By adjustment of the LED spectra a bigger range in melanopsin effectiveness factor, at the same CCT range (from daylight like CCT down to dimmed halogen), can be obtained.
