Claim 0:
1. A lighting apparatus comprising:
a first light engine that produces a first light spectrum having a first correlated color temperature (CCT), the first light spectrum comprising a first emission peak in a first wavelength range of 450 nm to 480 nm and a second emission peak in a second wavelength range of 380 nm to 420 nm;
a second light engine that produces a second light spectrum having a second CCT, the second light spectrum having a third emission peak in a third wavelength range of 480 nm to 500 nm and a fourth emission peak in the first wavelength range of 450 nm to 480 nm, wherein the second CCT is less than the first CCT and a difference between the first CCT and the second CCT is at least 10,000 K; and
an enclosure around the first light engine and the second light engine, the enclosure having an optical diffuser, wherein the optical diffuser is positioned over a first region, a second region and a third region of the enclosure;
wherein:
the first region and the second region are separated by the third region;
the first light spectrum is primarily emitted from the first region of the enclosure;
the second light spectrum is primarily emitted from the second region of the enclosure;
a mixture of the first light spectrum and the second light spectrum is emitted from the third region of the enclosure; and
a total melanopic to photopic ratio (M/P ratio) emitted by the lighting apparatus and received by a user is greater than 1.0.
