Audi is quick to point out they are the first car manufacturer to develop this
“revolutionary technology of the future”, however, they cannot take all of
the credit. Also involved in the research and development were LED
manufacturers Philips Lumileds Lighting of California and Automotive Lighting
from Reutlingen Germany.

The all LED headlight is fully functional for daytime running lights
(which is already available on the R8, A5/S5, S6 and since 2004 on the A8 W12
quattro), turn signals, dipped low beam and high beam lights. Each headlight
unit uses 54 LED light sources and is especially remarkable for its low energy
consumption (50 watts for the low beam headlights, 6 watts for the daytime
running lights). The LEDs are arranged in clusters or “arrays” which function
together as a single light source. In reference to the page photo above, the
LED lamp assembly is separated into four areas:

LED low-beam headlight module:
LED近燈模組
basic light distribution by an array of four LEDs for each of the upper and
lower reflector shells, range and light/dark boundary via the plastic lens
from three arrays of two LEDs.
在這模組中 每一個上下反射罩中 各有一個 由四個LED組成的陣列(應該是打上方和下方)
平行的光線 則由板狀透鏡後方的三個陣列投射形成 每個陣列有兩個LED
(難道 這是新一代的投射式燈具:魚眼→魚板?)
不確定這個透鏡只是單純的板狀平面鏡 還是板狀凸透鏡

圖中編號2.
LED high-beam headlight reflectors:
LED遠燈反射面
one array of four LEDs per reflector shell.
每個反射罩裡 有一個由四個LED組成的陣列

LED turn signal:
LED方向燈(轉向信號)
eight yellow high-performance LEDs.
八個黃色的高效能的LED組成

圖中編號4.
LED daytime running light strips:
LED 白天行使用的燈條?!(這是啥鬼? 白天用的定位燈?)
24 white Advanced Power TopLEDs with optical fibers for homogeneous
illumination.
二十四個白色高功率LED 和 光纖 提供均勻的照明(亮度)

In addition to these four sections, there are also two cooling fans, one for
each low and high beam. According to Audi, since the amount of heat generated
by the LEDs is low, the fans serve to circulate heat forward to the plastic
lens in order to melt ice or snow instead of acting as a cooling device for
the high and low beams.

However, despite revolutionary technology aspects, there are also major design
implications. As a result, car designers now have increased flexibility to
explore alternative headlamp shapes and configurations which beg the question:
is the conventional headlamp a thing of the past? Andreu Sola Gomfaus, Head of
Lighting Design at Audi, suggests, no. “Because the LED light no longer comes
from a single light source, the LED arrays are very flat and compact and occupy
much less space than conventional headlights, it will in future be possible to
transform the face of a car much more easily. Several LEDs can moreover be
combined in all manner of shapes, for a striking look.” However, Gomfaus goes
on to explain that the headlamp shape is not going to disappear. Cars are still
consumer products which are the slaves of human emotions and virtues. In
addition to many other components, designers depend on headlamp design to give
vehicles soul and identity. The challenge now is to find a balance between
function and aesthetics which is nonetheless an exciting aspect of future car
design.



全部都LED化就是了...
