Ambilight Electrochromic Smart Dimming Sunroof

Ambilight Electrochromic(EC) Smart Dimming Sunroof represents a breakthrough in intelligent automotive design, engineered specifically for adaptive light management in next-generation EVs. With a groundbreaking dimming ratio exceeding 40× — the widest globally , it offers the precise control of transmitted light across a 40× range at the touch of a button to suit varying lighting needs. Visually, this translates to a transition from crystal-clear to near-black.

As the world’s first company to mass-produce large-area curved electrochromic (EC) glass, Ambilight redefines how vehicles interact with light. Unlike traditional glass, which passively blocks or filters, this EC sunroof actively responds to environmental conditions — dynamically shaping the cabin’s light atmosphere with precision and elegance.

The core innovation lies in its flexible EC film, which conforms to complex curved vehicle roofs — enabling greater design freedom and integration with futuristic vehicle aesthetics. Crafted for powerful functionality, it blocks 99.9% of harmful UV and infrared radiation, significantly reducing interior heat buildup, lowering air conditioning usage, and contributing to reduced vehicle emissions. This not only enhances passenger comfort in all weather conditions but also aligns with global sustainability goals.

Control is effortless and intuitive. Users can adjust transparency through voice commands, mobile apps, infotainment system or ambient light sensors. The system supports OTA (over-the-air) updates and can adapt automatically to changing light conditions based on pre-set user preferences — creating a personalized and intelligent cabin experience.

Manufactured using eco-conscious materials and energy-efficient processes, the sunroof reflects Ambilight’s commitment to sustainable innovation. It exemplifies the fusion of material science, user-centered design, and scalable engineering — offering an elegant and functional solution that elevates both the driving experience and environmental responsibility.

Ambilight’s EC Smart Dimming Sunroof marks a pivotal advancement in automotive design. It not only transforms the way we manage light inside vehicles but also sets a visionary standard for the future of automotives — where beauty, performance, and sustainability move in harmony.
