Leverkusen, February 20, 2014 – Winter days are short, and brightness is in short supply. It is essential that homes, cars and streets be well-lighted at all times to avoid compromising safety or comfort. This can be best achieved using light-emitting diodes (LEDs). Because they are not only more durable than traditional sources of illumination, but also save energy and produce a higher quality of light, the semiconductors are on the rise. Bayer is supporting this trend with its high-performance plastic polycarbonate, the material of choice for important LED components.

Electric lighting has become so matter of course that progress in this area often goes virtually unnoticed. Light-emitting diodes, which were introduced roughly five decades ago, are now used nearly everywhere in daily life – from street lamps and car headlights to lighting in homes and yards.

Not only do consumers benefit from their long service life, LEDs are also easier on the household budget because light-emitting diodes consume far less energy than conventional light bulbs. According to a recently published report (1), real per household expenditures on electricity have increased significantly between 2007 and 2012 – a fact the authors believe could further increase LED sales.

Bayer MaterialScience develops and produces special polycarbonate grades for crucial LED components such as lenses and light guides. “LED is a highly energy-efficient lighting technology and is already changing the future of lighting worldwide,” says Roger Lian, marketing expert at the Polycarbonates Business Unit. “LEDs last longer, are sturdier and offer better light quality than other light sources. Polycarbonate from Bayer MaterialScience is the ideal material for the production of LED components because it is tough, lightweight, easy to shape and easy to process.”
