Photostrophism Light / Photostrophism Light

Photostrophism Light
Photostrophism Light

We introduce a new configuration of solar lights, which provides a street lights design with full coverage of solar power radiation.

The phototropism analogy of plant is referred in our design, which includes a lights panel and a leaf-alike solar panel.
In day time both panels will be retracted with solar panel pointing outward.
It will be tilted and rotated by servo mechanism to normal to sunlight.

This integrated mechanism is energy efficient and structurally rugged, which makes it an excellent green design.
