Gallery: Sharp’s Earthquake Detecting Solar Streetlights


Although not as aesthetically pleasing as those bio-mimicking Leaf lamps, these solar streetlights not only provide ample nighttime lighting, but also offer assistance in the event of a major earthquake. Sharp‘s streetlamps charge during the day and light up the night with their powerful and energy-efficient high-intensity LED spotlights. In the event of an earthquake measuring 5.0 or greater, these streetlights will turn on full brightness all night long to light streets and sidewalks, aiding in emergency relief efforts.

Sharp‘s new lights will soon be introduced to the Japanese market in parks and other areas that require spot or security lighting. Each light delivers 1,800 lumens, which is equivalent to a conventional 38-W fluorescent security light. This unit will save 48 kg of CO2 compared to the conventional security light and it will provide emergency lighting in the event of a major earthquake. Seeing as how Japan is located on the Ring of Fire, an area known for it’s seismic activity, these solar streetlamps stand to provide an important resource for rescue and rebuilding efforts.

LED light also boasts an additional benefit – it doesn’t attract insects. According to Sharp: “Insects have a behavior (phototaxis) in which they tend to congregate in the vicinity of light having a wavelength in the ultraviolet range of around 350 nm. Conventional lighting (fluorescent or incandescent lights) generates ultraviolet light in this wavelength range and insects readily congregate around these light sources.” LEDs generate very little ultraviolet light, which means that the lighting fixtures will not need to be cleaned as frequently, so they will require less maintenance over longer periods of time.

    why does useful design can’t be pretty ??? this light can save your life but spoils the view….

    It’s a good invention. Where there is a will there is a way. It’s a necessity. Necessity is the mother of all inventions.These are the futuristic street lamps of the future.

    What is their life expectancy and recharge cycle before battery replacement? Do they “last the night”?

    Everybody has Wind and solar powered lights and energy sources for the home. We all want this and will pay good money for them. But just you try and buy one. Japan has great stuff. NOT SOLD IN CALIFORNIA OR THE UNITED STATES.
    Just ask a solar contractor to build an Off the Grid system and they will run in the other direction. I\\\’ve been looking for a street light for years. I\\\’ll be damned if I can find one. Or not sold to individuals only Cities. STILL LOOKING
