Oslon Signal bright blue LED for police and emergency services vehicles

Osram Opto Semiconductors’ Oslon Signal LED is claimed to provide the world’s brightest blue light. Made using a special thin-film chip technology, the Oslon Signal’s bright blue light enhances visibility, making it suitable for police and emergency services vehicles. The LED can be operated at a high current and provides steady brightness in all applications.

The LED produces a blue colour with a luminous flux of 52 lm at 350 mA. Its wavelength of 472 nm and all colour bins (groups) comply with the US and EU standards for signalling, 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 ageing caused by the short-wave blue light.

The Oslon Signal incorporates high-performance UX:3 chips, which are capable of operating at high performance levels even at high currents. This is an important attribute, as blue signal light is often pulsed and therefore requires even greater luminous power at high currents.

The LED measures 3 x 3 mm and is equipped with an electrically isolated heat slug, so it can be mounted easily 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 brighter signal lighting.
