FIELD: lighting engineering.
SUBSTANCE: invention relates to lighting engineering and is used to generate ball-shaped light flow in ball light emitting sources for lamps with point source of radiation, for example, light-emitting diode with focusing element. Method for correction of directional pattern of ball radiation generator light-emitting element, including formation of radiation from light-emitting element through the radiation focusing element, is characterised by that to form smooth type beam pattern of radiation transparent body is placed in a matte ball shell and transparent body is preliminary divided into volume lightguide sections (light guides), in each of them mirror coatings are made, which perform through openings at the input light guides of transparent body the distribution of focusing element light flow to the opaque inner surface of ball shell radiation generator; amplitude of the input light flow is measured as well as directional pattern of radiation emitted by the focusing element. Magnitudes obtained by calculations or by means of measuring instruments are angles of boundaries of radiation with equal light flows at inputs of the light guide sections, radiation is measured at the output of generator shell and the initial radiation pattern of radiation generator is determined, then for balancing the maxima of radiation amplitude from shell on adjacent boundaries of the outputs of sections without changing the common boundaries of the input opening angles are measured; once more boundaries of radiation to set new dimensions of openings at inputs of the light guides and this is performed with reduced emissions of amplitudes of the first type of smoothing radiation on the beam pattern of radiation generator; radiation at the other balancing radiation with shell radiation generator at adjacent boundaries of the outputs of sections the maximum amplitude with minimum previous one are obtained at the output of the second type of radiation at radiation beam pattern former radiation that repeats the stretched input, while aligning the amplitudes of radiation with shell relative to previous from central section on adjacent boundaries of the outputs of sections at alternate , direct and inverted, projecting light flow in adjacent sections on shell of radiation generator is the third type of smoothing radiation approximated to ball shape.
EFFECT: formation of a ball-shaped light flow in ball light emitting sources for lamps with point source of radiation, for example, light-emitting diode with focusing element.
