FIELD: electricity.SUBSTANCE: invention is referred to radio engineering and automotive industry, in particular to stabilisers stabilising characteristics of electric circuits, and may be used in devices stabilising light intensity in electric equipment of automotive vehicles. Technical result is oriented towards improved reliability and stabilising quality of LED intensity. Technical result is attained due to the fact the stabiliser contains additional in-series resistor and light-emitting diode (LED) coupled to the stabiliser output, and a divider element connected between the base and negative pole of the source is made as a photocell and located in the pathway of LED light flux.EFFECT: invention improves reliability and stabilising quality of LED brightness due to changes in wide range of LED glow intensity at small changes in supply voltage; it also has larger functionality.1 dwg |
