Exterior Body Electronics

Exterior body electronics combine LED lighting, sensing, and user-interface functions to improve visibility, safety, and styling. Lighting systems include adaptive driving beam (ADB) headlamps, fog lamps, daytime running lights (DRL), animated turn signals, center high-mounted stop lamps (CHMSL), and rear combination lamps that integrate stop, tail, turn, and position functions. These applications require LED current control, smooth dimming and animation, diagnostic monitoring, and reliable operation across automotive voltage and temperature conditions.

Lumissil semiconductor solutions support these exterior systems with LED drivers, microcontrollers, capacitive-sensing devices, DC/DC regulators, and communication interfaces. Applications include capacitive-touch door handles for keyless access, illuminated EV charge ports that provide charging-status feedback, and intelligent exterior lighting modules that coordinate dynamic welcome sequences, animated signaling, and adaptive beam functions. Together, these technologies enable distinctive vehicle styling, improved driver awareness, and control of exterior body electronics.
