<p>The system has several light sources designed as cosine-emitter in form of light emitting diodes. Many individual light-diode chips (11) closely packed are arranged along a circular line. The chips are partially sealed with a resin, in which ortho-silicate illuminated material is incorporated for transformation of lights, radiated from the diode, into another wavelength range. The diodes have different spectral characteristics.</p> |
