Lisovenko D. Technical realization of light signal system for take - off quick turning on the basis of light - emitting diode radiators.

The dissertation is devoted to the working out of scientific and methodical basis of technical realization of light signal system for take - off and landing runways of quick turning on the basis of light - emitting diode radiofors with the possibility of geometry and light streams spectrum control.The author has developed light - emitting diode radiators of full colours on flexible elastic membranes. It gave the opportunity of using them in different light signal and navigation instruments instead of traditional lamps. To achieve it the light - emitting diodes of three main colours of radiation are placed on the membrane surfice. Radiation indicator control is possible due to the change of membrane surfice curvature. As a result we have the position change of optical axis of each light diode that leads to the light stream expansion which either transforms into fan or becomes narrower gathering into pencil of rays.The mathematical model and the method of membrane construction of light - emitting diodesearchlight calculation have been worked out. Now it allows to control light stream. Such searchlight can be used for long distance signalling and as a floodlight. This method allows to choose construction and membrane materials, to calculate its changable position and form spherical profile of caving for light stream control and change of focal distance. Light - emitting diode searchlight gives the possibility of spectral composition of light stream control, taking into account real natural and atmosphere conditions, regulating correlation of light streams of light diodes with different spectral compositions of radiation.
