SELF-CONTAINED MULTIPURPOSE LIGHTING UNIT Russian patent published in 2015 - IPC F21L4/08 F21S19/00 

FIELD: electricity.

SUBSTANCE: in self-contained multipurpose lighting unit containing flexible layered structure on which the chains of semiconductor solar elements, a light source as a line of light-emitting diodes, the battery and the control unit consisting of the illumination sensor, the battery charge controller and assembly of regulation of energy supply to the lines of light-emitting diodes are placed; as a flexible layered structure the flexible photo-electric module is used the solar elements and lines of light-emitting diodes of which are located on a front and back sides of the module, and the control unit and the battery are fixed on one of the sides of the module. The control unit in addition contains the sound alarm system assembly, temperature and pressure sensors and bidirectional radio modem, meanwhile the lines of light-emitting diodes, the battery and the control unit are located under the optically transparent protective laminating film the thickness of which is 0.2÷1.0 mm.

EFFECT: improvement of reliability of the device and expansion of its functionality.
