There aren’t many stars beaming down at you at night in metro areas because of light pollution – the name for misdirected artificial light. A team of scientists has outlined a new LED street lamp design that could help reclaim the luminosity of the heavens.
A pollution solution devised by a team of Japanese and Mexican researchers was published yesterday in the journal Optics Express. The design is multi-fold. It outfits street lamps with a cluster of LEDs and specialized lenses that are mounted inside of a reflective box covered with a microlens sheet that resembles the shape of insects’ eyes, according to information found in the study’s abstract.
