1. A solar-operated lighting device comprising
a substantially tubular solar module, which is positioned vertically in a mounted position, the solar module having an upper end being located above a lower end of the solar module in the mounted position, wherein the solar module electrically powers a light via at least one rechargeable battery and an electronics module,
the at least one rechargeable battery and the electronics module each being arranged in an interior of the solar module with radial spacing therefrom,
wherein the solar module has an upper cover at its upper end and a lower cover at its lower end, and
wherein the solar module has an upper annular gap or ring of openings, which forms an upper ventilation opening in an upper interface region between the upper cover and the solar module, and a lower annular gap or ring of openings, which forms a lower ventilation opening in an interface region between the lower cover and the solar module, such that the solar module, in the mounted position, is traversed by a flow of cooling air flowing by convection from the lower ventilation opening to the upper ventilation opening resulting in a convection cooling of components contained in the interior of the solar module, and
wherein the lower cover includes the light.
