As a leader in aerospace and defense components, Cevians delivers lighting solutions that meet the most demanding civilian and military requirements. From NVIS LEDs and filters to optical overlays, every product is engineered for mission-critical reliability.
As LEDs have become the preferred source of illumination for aerospace instrument lighting, Cevians High Contrast LEDGEN optical overlays and legends provide exceptional performance.
The Problem: Visibility Challenges in Modern Cockpits
Modern cockpits present significant visibility challenges, with pilots needing to distinguish between lit and un-lit indicators in all lighting conditions, including direct reflected sunlight. Direct reflected sunlight can often interfere with readability, unfortunately increasing the risk of pilot misinterpretations and false readings. In critical scenarios, even minor confusion can have deadly consequences, making clarity essential.
The Solution: LEDGEN Advanced Optical Technology
Our advanced LEDGEN technology eliminates false images by creating a total dead face when not illuminated, thereby reducing the possibility of pilot misinterpretation or false readings.
With superior contract performance and exceptionally high transmission, LEDGEN outperforms standard market solutions.
By leveraging our proprietary polymer synthesis and advanced optical bonding processes, LEDGEN’s precision and reliability are unmatched. As LEDs have become the preferred illumination source for aerospace instrument lighting, LEDGEN has set a new benchmark for performance.
It is engineered to deliver:
- Superior Sunlight Readability: Compliant with MIL-S-22885 for contrast and MIL-STD-3009 for night vision compatibility.
- Deadfront Technology: Indicators remain invisible until illuminated, maintaining a clean, high-contrast surface.
- Custom Engineering: Adjustable thickness, fonts, colors, and even split legends with zero crosstalk.
- Exceptional Uniformity: Optimized transmission ensures consistent brightness across every indicator.
Applications Across Aerospace and Defense
LEDGEN provides unmatched clarity for a range of cockpit and control applications, including:
- Illuminated pushbutton switches
- Annunciators
- Indicators
- Caution and warning panels
These applications demand not only reliability but also flexibility, qualities that LEDGEN provides through its fully customizable design.
