Automotive Lighting Vents

Protect & Ventilate Large & Small Automotive Lamps

Venting solutions

Customized membranes provide protection against dust, water, and dirt while also enabling gas exchange for venting and pressure compensation in large lamps such as headlights. 

Automotive Large Lamps

More efficient ventilation and protection are increasingly demanded for automotive lighting applications. Clear glass systems used in headlights need not only adequate airflow to cool the system but must also prevent condensation of moisture and protect against the ingress of liquid, dirt, and other contaminants that can lead to malfunctioning and reduced illumination.

Oxyphen’s expertise in the automotive market led to the development of specific hydrophobic, high-gas flow track-etched membrane solutions with unmatched vapor transmission rates that provide fast de-condensation and protection of headlights, rear lights, and other large automotive lamps.

Vents for Automotive small lamp
Customized membranes provide protection against dust, water, and dirt while also enabling gas exchange for venting and pressure compensation in small lamps such as mirror lamps, fog lamps, reflectors, ambient lights, and more.

Automotive Small Lamps

For side indicators, fog lamps, or other lightning devices where the mounting spot is on the vehicle’s exterior and directly exposed to the harshest weather condition, fogging and cracks can occur. To function properly, these lighting systems must have proper airflow for cooling, prevent the ingress of contaminants such as liquid and dirt particles, as well as prevent condensation of moisture which can all lead to malfunctioning of the part.

Oxyphen’s hydrophobic track-etched membrane solutions with unmatched vapor transmission rates offer an ideal solution for small lamps used in automotive applications through their ability to remove moisture, protect against contamination, and cool the module through a pre-determined airflow.
