Oslon Signal LED Blue Light

Osram Opto Semiconductors’ new Oslon Signal LED currently provides one of the world’s brightest blue light. Made using a special thin-film chip technology, the Oslon Signal emits powerful bright blue light providing significantly brighter signal lighting to enhance the visibility that is so critical for police and emergency services vehicles. The Oslon Signal can be operated at a high current and provides steady brightness even in the most demanding applications.

The Oslon Signal produces a blue color at an unprecedented brightness level, 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 US and EU standards for signaling, particularly 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.

Double the increase in brightness

The Oslon Signal incorporates high-performance UX:3 chips, 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 even greater luminous power at high currents. Despite its powerful output, the LED measures only 3 x 3 mm and is equipped with an electrically isolated heat slug, so it can be mounted easily and conveniently 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 also be easily mounted in existing emergency vehicle lighting applications to provide significantly brighter signal lighting.

In addition to blue LEDs, the Oslon family of LEDs includes a variety of other colors such as red, yellow, green and white, which all use the latest thin-film chip technologies, making them particularly effective in a broad range of applications including emergency vehicle lighting, auxiliary signaling, warning beacons and other similar applications.
