At the recently concluded launch event for the all-new Li Auto L9, a cutting-edge cabin lighting technology attracted industry attention—the electrically adjustable glass jointly developed by Li Auto and Fuyao Glass made its official debut as a core cabin feature of the all-new Li Auto L9, marking the mass production debut of Li Auto’s third-generation EC technology in the high-end intelligent vehicle field.
The electric dimming glass featured in the new Li Auto L9 transforms the core technology of Li Auto into a cabin experience that users can perceive, defining a new standard for cabin light control from privacy, personalization, sun protection, low energy consumption to high safety.
Ultimate privacy protection, freedom of privacy in all scenarios.
The third-generation EC technology of Lanrui achieves a light transmittance of 10%–12% in bright conditions and as low as 0.25% in dark conditions, with a dimming ratio of over 40 times. In dark conditions, the interior of the car is completely invisible from the outside, solving the pain point that traditional window tinting still cannot prevent the leakage of information from electronic screens. It can be used with peace of mind in scenarios such as changing clothes, resting, and business meetings, creating a private space for your “mobile home”.
Humanized and gentle light adjustment, adapted to the pupil’s light-sensing rhythm.
Abandoning the discomfort of instantaneous switching in traditional solutions, it adopts a gentle half-minute color-changing rhythm, first quickly controlling the light and then slowly transitioning, ensuring that the amount of light entering the vehicle always stays within the comfortable range for the human eye, without sudden changes in stimulation or delayed glare. Multiple adjustment levels adapt to the different lighting needs of various weather conditions and different groups of people. Instant response combined with a soothing dimming rhythm balances technological efficiency with driving comfort.
Robust heat insulation and sun protection reduce overall vehicle energy consumption.
The new generation of EC material can block 95% of infrared rays and 99.9% of ultraviolet rays, which is superior to sunshades and traditional physical color-changing heat insulation. It significantly reduces the temperature rise inside the car under sun exposure and reduces the energy consumption of the thermal management system. At the same time, it protects the occupants and interior, alleviates the scorching feeling of the sun, and achieves both comfort and energy saving.
Neutral color tones align with the aesthetics of a high-end cabin.
The third-generation EC technology achieves a neutral, natural color tone, resolving the yellowing and greening issues of the previous generation. It better aligns with Chinese aesthetics and easily adapts to various interior design styles.
All-solid-state design with power-off memory ensures a solid safety baseline.
The all-solid-state technology, combined with power-off memory function, ensures that the light transmission state remains unchanged after power failure, resulting in more stable low-power operation. This avoids the safety risks of sudden changes in light while driving, eliminates visual obstacles for emergency rescue, and safeguards vehicle safety in all scenarios.
03: Mass production has been launched, ushering in a new era of light control for intelligent cockpits.
With the official launch of the all-new Li Auto L9, the Li Auto EC dimming technology will also enter more homes, defining a new standard for intelligent cockpit lighting control with the third-generation EC technology.
