A small-scale revolution in lighting
On the move with LED headlights
To enhance road safety, more and more countries are mandating the installation of daytime running
lights on cars. What’s the best way to meet this requirement without restricting freedom of automotive
design? The answer is nothing less than a small, yet revolutionary innovation: state-of-the-art headlights
equipped with tiny light emitting diodes (LEDs) from OSRAM. While the solution may sound simple, the
results are amazing engineers and designers alike. Featuring advanced chip technology and special
housings, the headlight LEDs emit powerful beams with the same color impression as natural daylight.
These extremely long-life LEDs also consume less energy than conventional lamps. And because they’re
so tiny, the LEDs can be congured in virtually countless ways to produce spectacular, eye-catching
headlight designs. The innovative devices have already been installed in daytime running lights on
Audi’s R8 and A4 models and the high-beam, low-beam and daytime running lights on Cadillac’s new
Escalade.
Fresh water for California
Water treatment – A long-term solution
As global population grows, supplies of drinking water are dwindling – particularly in the world’s arid
regions. One solution is water recycling. We offer high-tech water treatment systems for agricultural
and industrial applications and – indirectly – for providing drinking water. In California’s Orange
County Water District, for example, pre-treated wastewater was previously pumped directly into the
Pacic Ocean. Today, a membrane lter system removes suspended particles, bacteria and other impuri-
ties from the wastewater, which is then treated in reverse osmosis and oxidation systems and nally
mixed with other groundwater in inltration basins. The process reduces the amount of wastewater
released into the sea while creating a new source of clean water and improving water quality through-
out the local catchment area – just one of the ways in which we’re helping communities meet their long-
term water needs.
