FIELD: physics.
SUBSTANCE: electroluminescent device has at least one electroluminescent light source (2) for emitting primary radiation, preferably having wavelength between 200 nm and 490 nm, and at least one light-converting element (3), lying on the beam path of the primary radiation for partial absorption of the primary radiation and emitting secondary radiation, where the dimension of the said light-converting element (3) in the direction (5) of the primary radiation is less than the average scattering length of primary radiation in the light-converting element (3).
EFFECT: invention enables design of an electroluminescent device with conversion by a luminophor, which is characterised by high attenuation coefficient of the apparatus combined with a colour temperature which is as independent from the viewing angle as possible.
