METHOD OF MAKING LIGHT-SCATTERING FIBRE-OPTICAL ELEMENT AND FIBRE-OPTIC ELEMENT OBTAINED BASED ON SAID METHOD Russian patent published in 2016 - IPC G02B6/00 

FIELD: lighting.

SUBSTANCE: invention relates to lighting devices based on use of fibre optics and can be used in lighting devices in light engineering, in medicine for phototherapy and cosmetology. Method of making light-scattering fibre-optical element (FOE) consists in separate drawing rods of same or different mutually agreed cross-section of 0.4-6.0 mm of rods of round or polygonal section, made of silicate glass with high and low refraction index. Package with random distribution of rods of glasses with high and low refraction index in cross-section is made. Ratio of highly refracting and low refracting rods in packet is from 1:10 to 10:1, wherein size of cross section of single fibres in FOE ranges from 40 nm to 1,000 nm. Package is drawn in multi-core light guides (MLG) with the size of 50 mcm to 6 mm, from which further are extra-multicore (EMC) and extra-extramulticore (EEMC) light guides.

EFFECT: simple process of making light-scattering fibre-optic element, low labour input and higher efficiency of manufacturing process.
