This is a simple solar LED light that uses a hand-made solar collector to light up the middle LED light.
Incorporating more concepts into it, this outdoor LED fixture named Heliotrope is able to automatically collect solar energy following the sun. The shape of a collector, like a petal, mimics the biological characteristics of a sunflower and follows the sun's rays to change the steering angle. Suitable for installation in outdoor garden patio lights, each petal is a solar panel, generating electricity for the middle white LED bulb. The bottom uses a syringe to act as a piston to control the opening of the flower bulbs, and the temperature raises the pressure generated by the evaporation of alcohol inside, pushing the petals of the piston solar energy to unfold. The same luminaire creativity appeared on the LED petal solar LED street light of LED lighting house.
