ABSTRACT:
The invention relates to a luminescence conversion led based illumination deice that emits primarily radiation in the range of from 370 and 430 nm of the optical spectrum (peak wavelength). Said radiation is converted to radiation having a longer wavelength using three luminescent substances that emit in the red, green and blue range.
