With the Oslon Signal, Osram Opto Semiconductors launches 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 is crucial for the signal lights of the police and emergency services. The Oslon Signal is now available at distributor Rutronik.

The Oslon Signal produces a blue color at an unprecedented brightness level, with a luminous flux of 52 lm at 350 mA. Its wavelength of 472 nm and all color bins (groups) comply perfectly with the EU and US standards for signaling, in particularly for Emergency Vehicle Lightning. The package platform, 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 Oslon Signal contains 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 important, as blue signal light is often pulsed and therefore requires from high currents even greater luminous power. Despite its power, the LED measures only 3x3mm. Featured with an insulated heat sink, it can be mounted easily and conveniently. The lens hasa radiation angle of 80° and provides a highly symmetrical light output.
