Clever Solar Street Lamp Design Straps On To Existing Lights

Solar street lighting is an old idea but creating designs that don't mean installing major infrastructure is harder than it seems. Designer Mark Beccaloni came up with a way to add extra lighting to street lamps without needing to hook them up to the electrical grid.

The solar-powered design would simply strap on to existing lighting. While the old lights run off the electrical grid, additional lighting is added using solar power and LED bulbs.

From Yanko Design:

Parasite is a Photovoltaic Lamp that parasitically hooks onto existing lamps and scaffoldings, primping the old.

As the designer explains, “The cells are high in efficiency and use triple junction PV cells, brought to earth after extensive use in space. Their power depends on their nanotech wafer of GaAs (gallium arsenide), a modern material that has nothing to do with common Si (silicon) photovoltaic. These cells work at atmosphere 1 with extreme efficiency and can be forced further with a Fresnel lens, supporting a light intensity up to 1000 suns if correctly refrigerated. I estimated a 260-watt peak production in normal conditions while just covering far less than a square meter surface with these marvelous GaAs cells. Parasite tilts from a relaxed neutral position to 30° in order to harvest energy at its maximum, LED lights grant low consumption and produce an abundant number of lux.”

For areas low on quality outdoor lighting, these add-on lamps might be a perfect solution, while keeping the added environmental footprint as minimal as possible.
