LED照明汽車內部照明環境

　　環境或情緒照明車內主要是高端豪華車領域，如圖1中上面的奧迪A8，或熱情的汽車后市場系統定制安裝。但制造商的視野正在拓寬。

　　當然，汽車中的LED并不是新產品。所有汽車制造商都在使用LED。單一的LED已用于儀表板和儀表板20年以上的背后。頭燈和尾燈是最近最引人注目的革新，取代了傳統的照明技術。越來越多的LED被用于新的應用，例如背光開關來指示門把手或開窗器的位置。最近，他們發現他們的方式進入腳部，杯架（見圖2）和地圖袋，以及門和屋面板。更微妙的特性包括低層的彩色LED照明，例如輕輕地突出齒輪棒。

　　The economics and performance benefits of LEDs are convincing the automakers that these devices can provide a significant differentiator in terms of comfort and convenience in the family sedan or compact run-around. Ford， for example， has announced that its 2013 Fusion is the first to sport exclusively LED lighting throughout its interior. The model will be supplied as standard with lighting in the company’s signature ‘ice blue’ color. But， exploiting one of the benefits of LED technology， Ford can offer user-specified tones， including orange， red， green or purple.

　　Many other carmakers are focusing on interior lighting， not just to be functional， but also to add style and differentiation. Some， including Audi， Toyota and BMW are continuing research into ambient lighting to determine optimum colors and brightness levels， and how to improve the delivery of safety information dependent on the perceived mood of the driver. LEDs are likely to play a major role in future automotive interior lighting schemes.
