摘要： The invention provides a lighting device (100) comprising a) a light source (10) configured to provide blue light source light (11), b) a first luminescent material (210) configured to convert at least part of the light source light (11) into first luminescent material light (211) with light intensity in one or more of the green spectral region and yellow spectral region, c) a second luminescent material (220) configured to convert (i) at least part of the light source light (11), or (ii) at least part of the light light (11) and at least part of the first luminescent material light (221) with light intensity in the red spectral region, and d) a light exit face (110), wherein the lighting device (100) is configured to provide lighting device light (101) downstream from said light exit face (110), wherein the lighting device light (101) comprises one or more of said light source light (11), said first luminescent material light (211), and said second luminescent material light (221), and wherein the second luminescent material (220) is configured to be at least partly saturated with (i) light source light (11), or (ii) light source light (11) and first luminescent material light (211), at or above at least 50% of nominal operation power of the lighting device (100).

摘要： 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.

摘要： Lighting systems, devices, methods and apparatus for simulating a candle flame are disclosed. The systems and methods can employ spatially distributed, disjointed sets of light-emitting elements that are independently controlled (526) with randomized control signals to simulate a candle flame by forming spatially and temporally varying lighting effects. Further, the disjointed sets can be controlled (526) such that the total light intensity is essentially maintained. In addition, systems and methods can employ a transition probability model (508) to adjust intensities of light-emitting elements in a way that accurately mimics a candle flame.

摘要： A lighting device comprising a housing with a light emission window and, opposite thereto, a reflector. A planar light transmissive carrier arranged in between the light emission window and the reflector and comprising, at least on a side facing towards the reflector, a grid of a plurality of light sources. The plurality of light sources comprise a first group of first light sources and a second group of second light sources. Each first light source has a respective first emission orientation in a respective first direction away from the reflector and each second light source has a respective second emission orientation to issue light towards the reflector, which light, after reflection, is redirected into a respective first direction. The lighting device is able to provide accent lighting and/or diffuse lighting issued by light sources arranged on one planar carrier.
