OBTAINING METHOD
The novelty concerns obtaining of
the light-diffusing patterns inside the item made of transparent material with
subsequent illumination of the item by the illumination source. The proposed
technology differs from the known one in that the light-diffusing pattern is
shaped by formation of several groups of elements involving bodies of revolution.
In so doing, the longitudinal axes of the bodies of revolution in one group
should be arranged at a certain angle with respect to those of the bodies of
rotation of other groups. In item illumination at least two illumination sources
should be used with directional paths and different wave lengths for creation of
the required color spectrum.
The patent protects various
modifications of the offered method. They differ from each other in: angles of
inclination of longitudinal axes of the bodies of rotation in one group relative
to those of the other group (from 0 to 90o); illumination sources,
some of them have limited directional path and are arranged normal to the
longitudinal axes of the bodies of rotation of one or other group for selection
of the color spectrum of some groups of the bodies of rotation, are arranged at
various angles with respect to the maximum of the directional path for
observation of half-tints and obtaining light mixture of the light-diffusing
pattern; variation of illumination intensity for changing the pattern color
spectrum; employment of cylindrical and cone-shaped elements as bodies of
rotation.
