METHOD OF GENERATING CURVE OF SEARCHLIGHT INTENSITY, SEARCHLIGHT AND SPOTLIGHT ILLUMINATING DEVICE FOR METHOD IMPLEMENTATION Russian patent published in 2019 - IPC F21V8/00 

FIELD: physics.

SUBSTANCE: group of inventions relates to lighting engineering and can be used for projector installations of railway rolling stock, water transport, air transport, as well as to projectors with mirror reflector of spherical or parabolic shape. In a projector with a spherical reflector, a light-emitting diode device is used as a light source, having a radiator body made of heat-conducting material, which is made in the form of a horizontally elongated central body located so that its axis is collinear to the optical axis of the reflector. LEDs are placed on the optical axis and shifted relative to the optical axis in the focus of the reflector or nearby it. Electric power control device is connected to control elements. Disclosed also is a method of forming a curve of illuminator intensity.

EFFECT: technical result is improvement of reliability, improvement and expansion of functional characteristics of projectors with mirror spherical or parabolic reflector, namely: longer service life, improved visibility of the track ahead of rolling stock at night, which increases traffic safety.
