OSRAM launched high-bright blue LED for emergency services

Osram Opto Semiconductors has launched blue LED for emergency vehicle lighting producing world’s brightest blue light. Osram says it is 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.

Osram Opto Semiconductors’ Oslon Signal produces a blue color 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 package platform of the Oslon family, consisting of a ceramic substrate with built-in connecting contacts and a silicone lens, remains stable and resistant to aging caused by the short-wave blue light.

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.

Osram says 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.
