White feel-good light on the move

The new generation of the Mini Topled and Topled classics from Osram Opto Semiconductors produce light of a particularly high quality. The successful standard packages have been retained but now contain LEDs in a new brightness class with pleasant white light that is ideal for the interior illumination of buses, trains, aircraft and cars. And then there are properties such as durability, resistance to electrostatic discharge (ESD), improved corrosion stability and certification to automotive industry standard AEC Q101.

The new generation of Topled and Mini Topled LEDs from Osram Opto Semiconductors have been tailored to the demands of public and private passenger transport for high brightness and high quality. These light sources for interior illumination combine pleasant white light with a much longer lifetime of up to 50,000 hours. The LEDs are among the most economical on the market because as low-power components they consume only 0.1 W. Despite their low power their luminous intensity is impressive. From an operating current of 20 milliamps (mA) and at a color temperature of 6000 Kelvin (K) the new Topled produces 2400 millicandela (mcd). From the same operating current the Mini Topled achieves a typical luminous intensity of 1700 mcd at a color temperature of 4000 K, and 1900 mcd at 6500 K. Luminous intensity in candela (cd) corresponds to luminous flux in lumen (lm) emitted by a light source in a particular solid angle.

The new generation of the two LED types benefit from further developments in chip and package technologies resulting in continual increases in light output. Added to that are the many years of experience that Osram has as a supplier in meeting the requirements of the automobile industry. These requirements include the high ESD resistance (ESD stands for electrostatic discharge) of 8 kilovolts (kV) and improved corrosion stability. The semiconductor components are certified to the automotive supply industry standard AEC Q101 and therefore meet the requirements that rail, road and air transport systems impose on components for interior lighting. According to Nina Engel, Marketing Industry LED at Osram Opto Semiconductors, “Passengers need to feel comfortable however long their journey. LED light with different white tones helps create a feeling of well-being without compromising on brightness or durability.”
