According to Japanese media reports, Philips Lumiled s Lighting LUXEON Automotive strategic marketing director Dirk Vanderhaeghen said that the headlamps are equipped with LED DRL and headlight low beam. In terms of DRL, there are currently 5 to 10% of cars equipped with LEDs. This ratio is likely to increase significantly to 25 to 35% or more after five years.
The LEDization of the headlights' low beam is limited to "advanced cars", so the current ratio is less than 1%. In 2012-2014, LEDs will be equipped with models that are environmentally friendly, such as electric vehicles (EVs) and plug-in hybrid vehicles (PHEVs). The full deployment of LEDs in popular models is expected to be achieved between 2014 and 2015. But there is a need to reduce costs to achieve this goal.
While the cost of current white LEDs affects the marketing of related products, Dirk Vanderhaeghen said that the number and power consumption of white LED modules required to achieve the performance required for low beam are decreasing. Specifically, in 2008, Philips' white LED module needed to use 5 low-beam lights in each component, and the power consumption was as high as 50W. In 2009, the product not only reduced the number of white LED modules per component to three, but also reduced the power consumption to 33W.
Nissan's electric vehicle "LEAF (Chinese name: Listening Wind)", which will be launched in December 2010, is equipped with a white LED for headlamps that we developed on the low beam. On the low beam, each component is equipped with 2 LED modules. The luminous flux of each LED module reaches more than 500lm, and the power consumption of the entire module is reduced to 25W. At present, we are still developing LED modules with a luminous flux of more than 1000 lm with one white LED module. The power consumption is expected to drop to 15-20W. It is expected to be equipped on a car that was launched in 2013.
Involving ED's marketing on headlights, Vanderhaeghen said that there are only a very small number of cars that use LEDs on high beams. For example, "Audi R8 Spider" is the same. These high-priced cars don't have to worry too much about the cost. In fact, the high beam lights only account for 3% of the car headlights. From the perspective of cost, it is estimated that automakers will not actively adopt it.
