#汽車照明 #發光二極體LED #自動駕駛

【汽車照明，對於自動駕駛很重要～～～】

汽車技術正在經歷重大變革，透過控制 LED燈光來提高安全性的產品也在日益普及；此外，二輪車的技術和產品更新也是日新月異，且與汽車一樣對於品質的要求非常高。外燈由燈泡型發展為 LED 燈，使得光源可以變得更小、更薄；要想提高 LED 燈的設計靈活性，就需要提高LED 的輸出功率並降低驅動 LED 控制電路的功耗並實現小型化，延長使用壽命也是關鍵。

一般燈泡型燈具是以「達到一定壽命後可能會斷線並需要更換」為前提來進行設計；但 LED 燈通常是LED 和控制電路一體化的模組型產品，更換起來並不容易，是以「不會損壞」為設計前提，要求從元件品質開始就必須確保可靠性。近年備受矚目的「LED 驅動 IC 電路」，具有可實現更低功耗、透過內建的保護功能檢測 LED 故障以確保可靠性等優勢，可惜零件成本將隨之增加。

與此同時，越來越多儀表板指示燈採用小型 LED。為適應汽車嚴苛的溫度環境，一般會設定一個空間來避免遮光壁和電路板板接觸，但這會導致 LED 光線從這個空間向鄰近部位「漏光」，是亟需解決的課題。隨著自動駕駛普及，汽車照明不僅擔負著夜間照明和剎車時提醒後方的作用，還可望扛起向周遭通知車輛狀態之責。因此，LED 需要提高輸出功率，且 LED 驅動 IC 需能支援動態控制光源，並將資訊傳遞給外部環境的控制方式。

About author
2002年，憑藉獨特敏銳度察覺到電子業界需求，《COMPOTECHAsia電子與電腦》於中國大陸取得《COMPOTECHChina》月刊發行權，為初到海外發展及當地讀者出具最具前瞻性且中肯的觀察，具有相當影響力，也成為一流國際大廠競相展示研發心血的首選。 2006年，有鑑於網路環境日趨成熟，《COMPOTECHAsia電子與電腦》再度領先同業，首創線上視頻平台CTOV (COMPOTECH Online Video)。自此，成為整合紙本、網站、電子報及線上視頻的全方位媒體。 2016年，為貫徹市場應用及開發技術的連結並擴大群眾基礎，陸續展開 Facebook、Twitter、LinkedIn 等社群平台經營。 「就市論勢、就勢論市」是我們的信念。我們將於每週一、三、五下午在 FB 分享生活中隨處可見的科普知識，以平易近人的方式，用不一樣的角度觀察市場趨勢和技術走向，並不定時穿插轉載網路精彩佳作或趣聞。記得設為「搶先看」哦！ “COMPOTECHAsia/ China” issue on 8th monthly. It is the dependent media which focuses on electronic industry situation, end user market, and technology trend. The monthly magazine has become the main channel to get professional information for engineers, purchaser, R&D employees and decision-making management. We perceived the demand of electronic industry and strive to get the distribution rights of “China Edition” in Mainland China in 2002. It gives a lot of prospective and proper observation for the overseas workers and local readers. Gradually, COMPOTECH is getting to be the powerful. Nowadays, COMPOTECH is the first-choice platform for the first-class firms to display their R&D results. Furthermore, in 2006, we were ahead of our competitors to build the CTOV platform (COMPOTECH Online Video) due to the mature internet environment. Since then, COMPOTECH has become the integrated media. For having a thorough knowledge of market applications and technology migration, as well as expanding the base of the masses, we begin to manage the Facebook, Twitter and LinkedIn etc. in 2016.
智能系統設計／應用工程師、產品／專案開發主管、元器件／零組件／準系統採購者的交流園地，於每週一、三、五下午分享【科技應用取向】的趨勢議題。
