FIELD: illumination devices.
SUBSTANCE: illumination devices described use properties of light beam refraction. As light-penetrable material the liquid is used which liquid is placed into water-proof container provided with top transparent panel. Light reflector made in form of mirror is disposed in container. Mirror is oriented at some angle to container. There are two permanent magnets in container; the magnets are covered with silicon envelope. Any magnet has its axis attached to posts for oscillation movement at opposite phases. Two electromagnets are disposed at external surface of container. Electromagnets are oriented onto permanent magnets correspondingly. There is screen between side walls of case of illumination unit.
EFFECT: improved efficiency.
