FIELD: electricity.
SUBSTANCE: light diode lamp comprises a body with a fixed printed circuit board with light diodes, a primary optical system and a secondary optical system. Light diodes produce segments, where the primary optical system is directly installed, besides, above it there is the secondary optical system comprising groups of lenses, and installed as capable of radial displacement relative to the axis of the lamp.
