Non-pollutive streetlight detects earthquakes
Japanese company Sharp is now launching a solar-powered streetlight. Combining Sharp’s own solar modules and long-life, white LEDs, the Japanese company presents the environmentally friendly streetlight solution of the 21st century. The unit delivers brightness at the highest level; still the unit does not produce any light pollution, uses no mercury, and emits no ultraviolet light.
Storage batteries charge from sunlight during the day and shines automatically at night. The level of maintenance is minimal as Sharp’s solution only requires replacement once every 10 years.
One of the extra benefits that especially cities in earthquake zones will enjoy is the built-in seismic motion sensor. This feature enables the unit to detect any earthquake measuring five or higher on the Japanese Seismic Intensity Scale. When detected, the unit will turn on full brightness at nighttime hours for at least two days.
Initially, the solution will be available on the Japanese market. In Europe, the European Union applaudes companies who commit to the reudction of light pollution. Thus, the EU GreenLight Programme has been developed to involve public and private organisations in upgrading their lighting systems to reduce light pollution. Well-known B2C companies such as McDonald’s and Nike have been awarded partner status, while international operating B2B companies such as Amplex A/S and Reverberi Enetec are awarded the endorser status.
