AUTONOMOUS LIGHTING METHOD Russian patent published in 2022 - IPC F21S9/03 F21S8/08 

FIELD: autonomous electric lighting.

SUBSTANCE: invention relates to methods for autonomous electric lighting, more precisely outdoor lighting, in conditions of negative temperatures, designed to illuminate routes, roads, streets and objects in the absence of a centralized power supply. A method for autonomous lighting at a negative ambient temperature is claimed, in which a lighting lamp is connected by a signal from a light sensor and a motion sensor to an electric power source at night and disconnected during daylight hours, a convection air flow is created in a vertical pipe to rotate the impeller. During daylight hours, the inner wall of the vertical pipe is heated by solar energy through transparent windows in the pipe, which creates a convection air flow to rotate the impeller, the shaft of which, with a stirrer at the lower end, is placed in a non-freezing liquid in a heat-insulated container, to which a thermoelectric is connected on one side in the thermal insulation opening. element - a source of electricity for a lighting lamp, to the other side of which provide access to ambient air. The opening in the thermal insulation is automatically closed in the daytime with a heat-insulating screen, in which a hole is created, and opened in the dark at the signal of the light sensor. Additionally, the agitator shaft is joined to the wind wheel shaft, which is located in the upper part of the vertical pipe.

EFFECT: accumulation of thermal energy from solar energy during daylight hours and wind energy at any time of the day in a non-freezing liquid located in a heat-insulated container, with its subsequent conversion into electrical energy using a thermoelectric element, which is fed to a lighting lamp.
