Sharp designs new solar-powered LED street lights

It’s always really exciting for me to see big corporations like Sharp help to move the LED lighting industry forward. Their new solar-powered LED street lights should definitely help spur greater use of these energy-free lighting options, which should ultimately lower prices, for the rest of us!

Sharp Corporation recently introduced two new solar-powered LED street lights that include photovoltaics and white LEDs (light-emitting diodes). The LN-LW3A1 Solar-Powered Street Light casts light that’s as bright as the brightest in the industry (1,800 lumens) which is similar to a 32-W fluorescent security light that uses six compact fluorescent tubes. The light delivered by these fixtures is enough to distinguish the facial features of a person four meters away at night, which is enough distance to take evasive action if required.

Another great feature of these lights is their emergency setting. During an earthquake measuring 5 or greater (on the Japanese seismic scale), they will turn on to full brightness and stay on for two days, even during a power interruption.

The LN-LS2A1 on the other hand provide light at 1,200 lumens which is comparable to a 20-W security light, which is great for spot lighting in public spaces. Both models can reduce carbon dioxide emissions by approximately 44-48 kg each per year. What’s more, they both last approximately 40,000 hours and can be used for approximately 10 years before requiring any replacement.

And here’s something else I didn’t realize about LED lights. Apparently they tend to be less attractive to insects, which further reduces the maintenance of these fixtures since they require less frequent cleanings. This is because standard lights generate some ultraviolet light, which is attractive to insects. LEDs do not.

Both designs are made with corrosion-resistant, lightweight aluminum alloy, which makes them easy to install, long-wearing, and expandable. The anodized aluminum finish is protected with a matte paint coating, making them corrosion resistant, too.
