A new "off-grid" solution for lighting urban locations is found in "petals" from Phillips Electronics. Their concept is named: the "Light Blossom" and urban areas are the target market.
Phillips "petals" in the Light Blossom
"Light Blossom is an intelligent LED lighting system that can provide bright light when it senses people walking nearby, and decrease its luminosity when people aren't around. The technology is also energy-efficient and operates off the grid, gathering solar and wind energy during the day to use for light at night.
During the day, Light Blossom works similar to a flower, opening its "petals" to collect solar energy. As the sun moves across the sky, the petals gradually reorient themselves so they're facing the sun head-on to operate at maximum efficiency, similar to a sunflower."
The Light Blossommoves its petals into an upward, open position if cloud cover occurs or wind intensity increases which allows the petals to engulf the wind. Rotation of the petals under these conditions causes them to transfer the motion into their rotor feature that changes motion into energy.
"The Light Blossom continuously switches between solar and wind modes depending on weather conditions. It also displays its energy-collecting flow on its "trunk," or pole, with a decorative light for passers-by to see.
