FIELD: electricity.
SUBSTANCE: invention relates to the field of lighting engineering and relates to a device to control chromaticity of a light flux of a white light diode. The device includes a light diode of white glow, a transparent substrate, an air medium between the white light diode and substrate, and also a diffuser. The transparent substrate is equipped with a facility to convert a spectral component of white light made in the form of luminophore particles placed on the surface or in the material of the transparent substrate. The diffuser is equipped with spatially-structured elements made in the volume or on the surface of the diffuser. The distance between the substrate and the light-emitting surface of the diffuser makes less than 50 mm.
EFFECT: provision of the possibility to control chromaticity of light flux of a white light diode and reduced brightness of light-emitting surface.
