Evolving Demands: From “Illumination” to “Interaction”
In the era of intelligent cockpits, ambient lighting is no longer merely static illumination — it has become a vital component of the vehicle’s multimodal interaction system.
OEMs and Tier 1 suppliers are raising the bar for ambient lighting systems with increasingly complex requirements:
Multi-scenario dynamic lighting effects for driving modes, welcome/goodbye sequences, emotional ambiance, etc.
Real-time synchronization with signals from clusters, IVI systems, and door controls
Unified protocols, platform reusability, adjustable dimming, and traceable diagnostics
This means ambient lighting must not only deliver visual effects but also “speak the same language” — and that language is defined by communication protocols.
KEPO’s Ambient Lighting Modules Flexibly Support Multiple Protocols to Fit Project Needs:
LIN Bus: Cost-effective, ideal for low-speed modules such as door panels, footwell lights, and vanity mirror lights
CAN Bus: Used for center console and cluster lights requiring strong coordination with main vehicle systems
PWM Signal Input: Optional interface for legacy platforms or special-use cases
To ensure the timing, reliability, and compatibility of lighting effects across vehicle systems, KEPO provides comprehensive communication and functional validation support:
Message transmission/reception logic (including frame checks and error retransmission)
Master/slave configuration compatibility
EMC testing compliant with IEC/ISO standards
Cross-domain co-simulation and integration testing with HMI and BCM engineers
KEPO Advantages:
Integrated lighting controller design reduces development burden on Tier 1 suppliers
Supports custom communication formats and baud rates
Scalable to multi-sensory solutions combining lighting with sound effects
Aligned with OEM platform standards, enabling shared designs across multiple vehicle models
If you are seeking a communicable, customizable, and interactive ambient lighting solution for your vehicle platform, KEPO offers a one-stop solution tailored to your needs.
