Solar Trees - Streetlights Go Green via Solar Power and LEDs (GALLERY)
[Edit]
[Edit]
Here’s a great innovation in street lighting: self contained streetlights that are solar powered. They do not require underground lighting to install. The solar panels charge built in batteries which power LED’s. Less light pollution, less power, the lights have detectors to turn off and on automatically.
These self-contained streetlights could save cities energy and money too. Unlike regular streetlights, they do not require costly underground wiring to install, and they are immune to blackouts. Designed by Ross Lovegrove, the lights have 10 solar panels arrayed at the top of tree-like branches, which charge built-in batteries. The batteries then power LEDs for illumination. Compared to conventional streetlights, they emit much less light pollution, because LEDs generate a very directed light.
