Light conversion assembly, a lamp and a luminaire

Abstract

A light conversion assembly, a lamp and a luminaire is provided. The light conversion assembly comprises a first layer and a second layer. The first layer comprises first luminescent material. The first luminescent material comprises particles showing quantum confinement and have at least in one dimension a size in the nanometer range. The first layer is arranged to receive light from a light source emitting light of a first spectral distribution in a violet or blue spectral range. The first spectral distribution has a first peak wavelength. The first layer is configured to convert substantially all the received light towards light of a second spectral distribution in the blue spectral range, independently of the position of first spectral distribution in the violet or blue spectral range. The second spectral distribution has a second peak wavelength which is a longer wavelength than the first peak wavelength. The second layer comprises a second luminescent material. The second layer is arranged to receive light of the second spectral distribution and is configured to at least partially convert the received light towards light of a third spectral distribution being different from the first spectral distribution and the second spectral distribution.
