The invention provides a lighting system (), configured to provide lighting system light (), the lighting system comprising: &#x2014;a light source () configured to provide light source light () with light intensity in the blue spectral region; &#x2014;a first luminescent material () configured to convert at least part of the light source light () into first luminescent material light () with light intensity in the green spectral region and having a full width half maximum (FWHM) of at least 90 nm; &#x2014;a second luminescent material () configured to convert (i) at least part of the light source light (), or (ii) at least part of the light source light () and at least part of the first luminescent material light () into second luminescent material light () with light intensity in the spectral region of 610-680 nm; wherein the lighting system () is configured to provide at a first setting of the lighting system () lighting system light () comprising said light source light (), said first luminescent material light () and said second luminescent material light () having a color point (x; y) with x=0.38&#xb1;0.1 and with y=0.28&#xb1;0.1.

Meat lighting system with improved efficiency and red oversaturation

The invention relates to an illumination system (), to a remote phosphor layer (), to a scattering layer (), to a luminaire (), to a display device () and to a method of at least partially correcting a light emission characteristic of at least one light source () in the illumination system. The illumination system comprises an array of light sources () and a remote phosphor layer and/or a scattering layer arranged between the array of light sources and a light output window () for emitting the light from the light sources. At least one light source of the array of light sources comprises a light emission characteristic different from the other light sources of the array of light sources. The luminescent material () is distributed across the remote phosphor layer and/or the scattering structures () and/or scattering material () are distributed across the scattering layer for compensating at least partially the difference in light emission characteristic of the at least one light source. The effect of the illumination system according to the invention is that the deviation of the at least one light source can be compensated, and as such, binning of light sources may be omitted.

Illumination system with remote phosphor layer and/or scattering layer

The invention relates to a color-tunable illumination system (), to a lamp and to a luminaire. The color-tunable illumination system comprises a light source () emitting light of a first predefined color (B), and comprises a luminescent material () for converting light of the first predefined color into light of a second predefined color (A). The color-tunable illumination system further comprises shielding means () arranged for preventing at least part of the light emitted by the light source to impinge on the luminescent material. The light source, the luminescent material and/or the shielding means are changeable from a first situation to a second situation. In the first situation the color-tunable illumination system is arranged for shielding at least part of the luminescent material against impinging light of the first predefined color. In the second situation the color-tunable illumination system is arranged for shielding less of the luminescent material to the light of the first predefined color emitted by the light source compared to the first situation. The effect of the measures according to the invention is that the shielding means, luminescent material and/or the light source determine an amount of light of the second predefined color emitted by the color-tunable illumination system which determines a color of the color-tunable illumination system.
