Oslon Signal flashes its blue light

Osram Opto Semiconductors launches the brightest blue LED for emergency vehicle lighting


Hong Kong, 28 June 2012


With the Oslon Signal Osram Opto Semiconductors provides a new LED that currently boasts the world’s brightest blue light. Made using a special thin-film chip technology, the Oslon Signal can be operated even at a high current while providing a sustained, powerful, bright blue light. This powerful blue light that lasts even throughout long journeys is crucial for the signal lights of the police and emergency services.


Osram Opto Semiconductors’ Oslon Signal produces a blue color in a brightness level unprecedented
worldwide with a luminous flux of 52 lumens (lm) at 350 milliamperes (mA). Its wavelength of 472 nm
and all color bins (groups) comply perfectly with the EU and US standards for signaling, in particular for
Emergency Vehicle Lighting. The renowned package platform of the Oslon family, consisting of a
ceramic substrate with built-in connecting contacts and a silicone lens, remains stable to aging caused
by the short-wave blue light.


Double the increase of brightness

The Oslon Signal includes chips of the high-performance UX:3 technology, which are capable of
operating at very high performance levels even at extremely high currents. This is an important aspect,
as blue signal light is often pulsed and therefore requires from high currents even greater luminous
power. Despite its power, the LED measures only 3 x 3 mm. It is equipped with an insulated heat sink,
so it can be mounted easily and conveniently, especially in combination with a conventional FR4 board.
The lens has a radiation angle of 80° and provides a highly symmetrical light output; the Oslon Signal
can therefore also be easily mounted in existing emergency vehicle lighting applications and help
provide significantly brighter signal lighting.


“Our developers have succeeded in doubling the brightness increase with blue LEDs within a very short
time and therefore supplying the world’s brightest product in this sector. That’s why we support not only our customers in this regard but also contribute to greater road safety, as emergency vehicles can be
seen sooner and better”, says Jennifer Rieder, marketing manager at Osram Opto Semiconductors.


In addition to blue LEDs, the entire Oslon family of the Regensburg-based company includes a variety of
other colors such as red, yellow, green and white, which are all created using the latest thin-film chip
technologies, which make them particularly effective.
