結露、土ぼこりや水の侵入からヘッドランプを確実に保護

バッテリーEV（BEV）のヘッドランプが、より高温で動作する内燃機関車のヘッドランプよりも結露に弱い理由と、BEV のヘッドランプがドライバーと内蔵センサーにクリアな視界を提供し続けられるように、GORE® オートモーティブベントが他のベントよりも効果的に結露を除去し、車両の寿命を延ばすことができる理由をご説明します。

トヨタ自動車株式会社（トヨタ）では、潤滑由を含むギアと高電圧で駆動されるモーターを内蔵した油冷eAxleのソリューションを探していましたが、従来のベントソリューションでは対応できないことがわかりました。従来にない要件を満たすベントソリューションとしてGORE® Automotive Ventを採用した理由をご覧ください。このケーススタディーでは、トヨタが直面した課題、解決策、予定通りに開発スケジュールを進行できた結果についてご説明します。

有效防止凝露并阻止污物和水进入，为前照灯提供可靠防护

了解为何纯电动汽车的前照灯比工作温度更高的内燃机前照灯更容易出现凝露，以及与其他透气方式相比，戈尔®(GORE®) 汽车防水透气产品为何能够更高效地在汽车整个使用寿命期内提供有效的凝露清除和可靠防护，从而为BEV驾驶员和集成式前照灯传感器提供清晰视野。

As LED lighting proliferates in automotive applications, so does condensation. That’s because LED lamps’ heat source is at the rear of the assembly, making the lens area the cold spot where condensation forms most easily. Often with unpleasant results: foggy, cloudy or streaky lenses, and lamps that don’t shine as brightly as when they left the showroom. Condensation could also compromise integrated sensors or other electronic devices.

随着LED照明在汽车应用中日益普及，凝露问题也越来越多。由于LED灯的热源在组件的后部，使得透镜区域成为最容易形成凝露的冷点，从而带来一些不尽人意的结果，例如：透镜中出现雾状或条纹状凝露，灯具的明亮度不如出厂状态。此外，凝露还可能损坏集成传感器或其他电子设备。

Learn why Toyota Motor Corporation chose to partner with GORE® Automotive Vents when other venting solutions could not meet Toyota’s performance requirements for a new e-axle containing lubricated gears and a higher-voltage e-motor. This Case Study outlines the associated challenges, solution and results — including an on-time product launch for Toyota.

벤트 선택 시 가장 중요한 일은 먼저 애플리케이션이나 기기 또는 함체에 필요한 보호 수준을 정의하는 것입니다.

IP 등급을 NEMA 등급으로 ‘변환’하는 것은 불가능합니다. IP와 달리 NEMA에서만 요구되는 추가적인 테스트가 있기 때문입니다. 하지만 주어진 IP 등급과 대등하거나 그 이상의 성능을 제공하는 최소한의 NEMA 등급이 있습니다.

This document provides performance characteristics and specifications for GORE® Automotive Vents AVS 22 and AVS 23, suitable for rear lamps. Featuring a laminate construction, these low-profile adhesive vents provide a secure bond to the housing.

A critical aspect of vent selection begins with defining the level of protection your application, device or housing requires.

IP ratings cannot be “converted” to NEMA ratings, since NEMA requires additional testing not included in IP. However, there are minimum NEMA ratings that will meet or exceed a given IP code.
