Osram Topleds light up buses and trains
The gallium nitride (GaN) based LEDs in the Topled package combine special features such as ESD stability and corrosion stability with a feel-good light
Osram Opto Semiconductors' new generation of Mini Topled and Topled standard packages now contain LEDs in a new brightness class.
Osram TopLED
They have a pleasant white light suited to the interior illumination of buses, trains, aircraft and cars.
And Osram says these LEDs have properties such as durability, resistance to electrostatic discharge (ESD), improved corrosion stability and certification to automotive industry standard AEC Q101. The picture below shows the LEDs used in trains.
The new generation of Topled and Mini Topled LEDs 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 lifetime of up to 50,000 hours.
Osram claims 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 colour 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 colour 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 two new LED types benefit from further developments in chip and package technologies resulting in continual increases in light output ideally suited to automobile applications.
Apart from a high ESD resistance (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.”
