Audi A8 LED頭燈原廠技術資料 - 歐洲車

翻譯一些內容,當作練練英文也好
早年我最感興趣的頭燈是Q45的蒼蠅頭燈,
當初我甚至去日本殺肉買一組複眼燈組土炮在G35大燈上,效果還不賴,

近年最感興趣的頭燈就算Audi A8這組全LED了,
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The low beams comprise ten individual modules forming an arc situated
below the wing-shaped chrome contour known as the “wing.” Just below this
is another arc of 22 white and 22 yellow LEDs for the daytime running lights
and the turn signals.

近燈由10顆單元模組LED組成一個形似於鳥類翅膀的個體坐落於燈組下半部,原廠稱
其組成為"wing",而在"wing"下方有一弧形單元,其由22顆黃光和22顆白光LED所排列成,
當作DRL日行燈和方向燈(編按:文章中22顆白光和黃光為不同顆LED,所以意思是那條光條
含有22顆白LED合22顆黃LED共44顆發光晶粒,我一開始以為是可變電壓變色LED,同一晶粒
藉由電壓控制燈色)

Located above the wing are the high beams, whose light is generated by
two powerful four-chip LEDs and a free surface reflector system. An assistant
switches between the high and low beams, and additional high-power LEDs
generate the highway light and cornering light. A separate fan and heat sink
moderate the system's temperature.

在"wing"上方則是遠燈燈組,其由2顆高瓦4晶型LED和剩餘空間的反射鏡表面所組成,在
遠燈組和近燈組之間有一輔助發光系統,其含有高功率LED能投射距離遠的光在轉角處,
(作用類似AFS主動轉向頭燈),燈組外有風扇和散熱器系統降溫

With a color temperature of 5,500 Kelvin, their light resembles daylight and
thus is much less tiring to the eyes. They also offer efficiency advantages.
The low beams, for example, consume only 40 watts per unit, a bit less than
the already highly efficient xenon plus headlights.

此燈組色溫為5500K,其接近太陽光線能減少眼睛的疲勞,還有很大的優勢例如:近燈組
單元的總耗電瓦數只有40W,其耗電更少於目前已非常高效能的HID頭燈
