[A lighting device for medical endoscopes]

The author relates approaches to enhancing the effectiveness and safety of the lighting system of endoscopes. The optical and structural diagrams of the lighting unit for endoscopes have been devised. Pilot items of the lighting units based on an illuminating lamp 15-150, intended for flexible and rigid endoscopes of new generation have been manufactured. The unit provides for increasing the life of low-voltage filament lamp as well as for their work in the nominal mode within the range of the mains voltage fluctuations +/- 10% over the whole life.
