Claim 6:
7. A method comprising:
driving an elevator cabin along a vertical path using a traction wire rope;
providing a power source to the elevator cabin using a traveling power cable;
installing a housing unit within the elevator cabin, the housing unit containing a supercapacitor, an electronic circuit, and at least one light source;
distributing energy received at the traveling power cable, to power the at least one light source and charge the supercapacitor using any remaining energy; and
controlling, by a control system coupled with the electronic circuit, the distribution of the energy between the light source and the supercapacitor based on whether the energy satisfies an energy threshold,
wherein, when the energy received from the traveling power cable is insufficient to power the at least one light source, the electronic circuit draws energy from the charged supercapacitor to power the at least one light source for a period of time to allow sufficient power to be received from the power source.
