Osram Opto Semiconductors has announced a new member of its Oslon Signal family, a blue LED with a luminous flux of 52lm at 350mA. Its wavelength of 472nm and all color groups comply with EU and US standards for signaling, in particular for Emergency Vehicle Lighting, Osram said. The 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.
The Oslon Signal includes chips using 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 lights are often pulsed. Despite its power, the LED measures 3mm by 3mm. 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-degrees and provides a 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.
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.
