The sunflower-like device, a light receiver that dynamically tracks the light activity of sunlight, collected during the day, allows the collected sunlight to be sent via fiber optics to underground buildings, from where it is distributed to different rooms. The interior lighting fixtures of the rooms transmit sunlight with all its morning, afternoon and evening variations of color and intensity, and are duplicated by light - emitting diodes (LEDs) that are powered at night by electricity from photocell batteries, charged during the day from the lighting fixtures. Previously, the author developed a round-the-clock and continuous production of hydrogen and oxygen in a specially designed photoelectrolyzer-generator, achieved by using a lamp as a backlight for the photoelectrolyzer-generator, and an LED with a battery charged during the operation of the lamp, as a useful electrical load for the photoelectrolyzer-generator, which begins to illuminate the photoelectrolyzer-generator when the lamp is turned off until the battery is completely discharged, and continuously filling the photoelectrolyzer-generator with water. The round-the-clock production of oxygen and hydrogen in a specially designed photoelectrolyzer-generator allowed the author to carry out the round-the-clock and continuous charging of the fuel cell of an electric vehicle for its uninterrupted movement. This article discusses round-the-clock solar lighting of underground buildings, using a light receiver that dynamically tracks the light activity of sunlight, collected during the day, transmitted via optical fiber to underground buildings directly for lighting the rooms, which charges the batteries of photocells, located in the most illuminated places of these rooms, the electric current from which at night turns on LEDs, located next to the interior lights of the rooms, until the batteries are completely discharged in the morning. The-round-the-clock, continuous production of hydrogen and oxygen of the underground life support system in a specially designed photoelectrolyzer-generator is achieved by using sunlight from a light receiver transmitted via optical fiber as a light for the photoelectrolyzer-generator, and as a useful electric load of the photoelectrolyzer-generator, a light-emitting diode with a battery charged during the day by illuminating the photoelectrolyzer-generator with sunlight, which begins to illuminate the photoelectrolyzer-generator in the absence of sunlight at night until the battery is completely discharged in the morning, and continuous filling of the photoelectrolyzer-generator with water. The-round-the-clock production of oxygen and hydrogen in a specially designed photoelectrolyzer-generator allows of round-the-clock, continuous charging of the fuel cell of the electric generator of a life support system for uninterruptible power supply of the underground building.
