Osram expects that only 2% of the new cars produced globally will be equipped with LED headlights this year, and this number will become 20% by 2020.
Claus Allgeier, vice president of solid state lighting business at OSRAM, expects that the price of LED lights will gradually fall back to the same level as Xenon headlights in the next three years. He said: "The price of LED lights has been in the past 2-3 years. The change, while its performance has also been greatly improved."
Three years ago, Osram introduced a universal LED light unit similar to a small ice hockey. The unit is relatively low cost and can be applied to taillights, headlights, brake lights and the like. GM has equipped LED and other units on the Cadillac XTS and ATS. Ford and Mitsubishi used it for the fog light module, and BMW also applied it to the fog lights and headlights. However, Osram marketing director David Hulick said that although the LED unit is highly adaptable, it is not a universal component. He said: "As car manufacturers standardize LED lamp specifications, there will be more opportunities in the future."
Although some car manufacturers have developed headlights that can adjust the brightness adaptively, they all require mechanical construction. Osram and Hella's new technology does not rely on mechanical structures, and it also effectively prevents glare from oncoming vehicles. At present, the cost of matrix LED headlamp technology is too high, but it is gradually decreasing. Allgeier said: "The low beam has a field of view of 70 meters, and now this bottleneck will be broken."
