Lighting device and system with blue light regulation

Some embodiments relate to a lighting device, including a first lighting circuit and a second lighting circuit. The first lighting circuit includes at least one first light emitting device that is configured to emit light in a wavelength range of about 430 nm to about 490 nm, with a melanopic to pho...

Zusammenfassung:	Some embodiments relate to a lighting device, including a first lighting circuit and a second lighting circuit. The first lighting circuit includes at least one first light emitting device that is configured to emit light in a wavelength range of about 430 nm to about 490 nm, with a melanopic to photopic (M/P) lux ratio of about 0.8 to about 1.0 and a colour rendering index of about 80 to about 99. The second lighting circuit includes at least one second light emitting device that is configured to emit light that has a substantially reduced spectral power distribution across a wavelength range of about 430 nm to about 490 nm, with a melanopic to photopic (M/P) lux ratio of about 0.3 to about 0.4 and a colour rendering index of about 80 to about 99. The lighting device includes a switching unit to selectively switch power to the first lighting circuit and to the second lighting circuit.
