DVN met Peter Knittl, Director Marketing LED, Michael Brandl, Senior Manager Applications LED, and Marion Reichl, Manager Media Relations and asked them 4 questions about LED technology.
DVN: What efficiency Lm/w do you expect in the next 10 years when LED penetration will be much higher than today?
Osram Opto : Just five years ago we could see the first innovative vehicles on the road utilizing high power LED in forward lighting. A revolution of LED technology was essential to get to this point and with the Osram Ostar headlamp this technology was made available to the automotive market.
Now, it requires a significant effort on literally all technological contributors of an LED to increase performance not only on a lab scale. So, the LED chip, the phosphor converter, the material interfaced and the packaging technologies have to incrementally contribute to make an LED even more efficient down the road.
We could see in the past that an average of 5% of efficiency increase per year has been realistic.
DVN: Do you see a risk of LED logistics with the huge number of new LED models added with the 15 years to supply old headlamp models?
Osram: “Long Term Availability“ of LEDs for automotive applications is certainly a challenge, given the highly dynamic technological development of the industry:
