    Abstract: A method of emitting light from one or more light emitting elements, the method comprising: emitting a first time period of photopic light, followed by emitting a first time period of scotopic light, followed by emitting a second time period of photopic light, and followed by emitting a second time period of scotopic light; wherein a first transition from the first time period of photopic light to the first time period of scotopic light is different compared to a second transition from the second time period of photopic light to the second time period of scotopic light, and/or wherein a third transition from the first time period of scotopic light to the second time period of photopic light is different compared to a fourth transition from the second time period of scotopic light to the first time period of photopic light or a third time period of photopic light.

    Abstract: Lighting device includes a first concentrator with a first luminescent material, a second concentrator with a second luminescent material having an absorption band overlapping with the emission band of the first luminescent material, and a plurality of light sources arranged to project light into a first input surface of the first concentrator to be converted at least partially into a first converted light by the first luminescent material and outputted from a first output surface of the first luminescent concentrator. The second concentrator arranged parallel to the first concentrator such that light from the light sources that leaks from a side surface of the first concentrator is received by the second concentrator and converted by the second luminescent material and outputted from a second exit surface of the second concentrator. The first and second concentrators having different lengths.

    Abstract: A lighting device includes at least one first light-emitting element configured to emit a first light of a first wavelength range; and a light guide having axially opposite first and second base surfaces, and a plurality of segments, each with a first light in-coupling surface formed on a lateral surface of the light guide, each of the segments configured to convert at least a part of input light into second light having a selected wavelength range. At least a portion of the first base surface includes a second light in-coupling surface and at least a portion of the second base surface includes a light out-coupling surface. The lighting device is optically coupled to the second light in-coupling surface such that the first light is coupled into the light guide, and the first light emitting element is configured to reflect at least part of the second light thereon having a wavelength within at least one of the selected wavelength ranges back into the light guide.
