Phosphor enhanced light source for presenting a visible pattern and a luminaire

A phosphor-enhanced light source for presenting a visible pattern, the phosphor-enhanced light source comprises:

• a light exit window for emitting light into the ambient of the phosphor-enhanced light source,
• a light emitter for emitting light of a first color distribution towards the light exit window,
• a luminescent layer comprising luminescent material for absorbing a part of the light of the first color distribution and for converting a part of the absorbed light into light of a second color distribution, at least a part of the luminescent layer forming at least a part of the light exit window, the luminescent layer comprises a first area and a second area being different from the first area, the first area and the second area forming a pattern,
• wherein
• a first light conversion characteristic of the first area is similar to a second light conversion characteristic of the second area for obtaining a first light emission by the first area into the ambient and a second light emission by the second area into the ambient, the first light emission and the second light emission being experienced as similar light emissions by a viewer if the light emitter is in operation, and
• a first reflection characteristic of the first area is different from a second reflection characteristic of the second area for obtaining a first ambient light reflection by the first area that is different from a second ambient light reflection by the second area if light impinges from the ambient on the respective first area and second area, the difference between the first ambient light reflection and the second ambient light reflection being visible by the viewer.
