New Solar-Powered LED Street Light Matches Fluorescent Lamps in Brightness

Major Japanese electronics manufacturer Sharp Corp. launched sales August 21, 2007, of its new solar-powered light-emitting diode (LED) street light that produces the top class in brightness rated for road safety, equivalent to that of a regular 32-watt fluorescent street light -- the first LED street lamp with such power.

Equipped with specially designed solar panels and a long-lasting, high-intensity LED system, Sharp's LN-LW3A1 model provides 1,800 lumens of light flux, satisfying the brightness criteria of Japan's standards for road safety illumination. The lamp is also equipped with an earthquake sensor, so it can function as a powerful security light during power failures. When the sensor detects a major earthquake of intensity of five or stronger (on the Japanese scale), it is able to light up at full brightness for 48 hours straight.

Solar-powered LED lighting is receiving greater attention as an ecological alternative to regular lighting technologies for a number of reasons. For one, using Sharp's lamp instead of an ordinary commercial light using power eliminates 48 kilograms of carbon dioxide emissions per year. Also, the LED system contains no mercury and little maintenance is required over its estimated 10-year lifespan, just one more advantage the company expects to fuel a large demand for its new street lamp.
