LED provides blue light for emergency vehicles

Tue, 06/26/2012 - 11:25am

Osram Opto Semiconductors’ Oslon Signal LED is asserted to provide the world’s brightest blue light. Made using a special thin-film chip technology, the LED emits powerful bright blue light providing to enhance the visibility that is so critical for police and emergency services vehicles. The LED can be operated at a high current and provides steady brightness even in the most demanding applications. The Oslon Signal produces a blue color a high brightness level, with a luminous flux of 52 lm at 350 mA. Its wavelength of 472 nm and all color bins (groups) comply 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. 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 important because blue signal light is often pulsed and therefore requires even greater luminous power at high currents. The LED measures only 3 mm x 3 mm, and it 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.
