We’ve covered some solar streetlights before, but this one’s got a unique twist: like the the sunflower, the Flower Solar Street Lamp by designer Luis MRPS of Portugal follows the sun in its arc across the sky. In this way, it soaks up as much solar energy as possible to provide power at night.
The source of illumination for this concept design is, of course, ultra efficient LED lights, which make the most of that juice while providing the bright light required by public lighting features.
Another thoughtful element: the Frisbee-like shape of the lamp’s top not only provides the perfect surface for a solar panel, it ensures that light from the lamp reflects downward, where it’s needed, rather than in all directions, contributing to light pollution. (This streetlight was designed with pedestrian areas in mind, such as parks, rather than areas dominated by cars.)
Simple and elegant, we like the way this streetlight tilts in the direction of the sun during the day, supplying electricity to the battery housed in its base. We imagine the sight of many of these streetlights, lined up in a row, slowly following the sun throughout the day, would no doubt attract curiosity from passersby.
