LIN-Lite Smart LED: Next-Gen Innovation for High-Efficiency Automotive Ambient Lighting

Reinventing Automotive Ambient Lighting

In modern vehicle design, lighting plays a critical role — not only for aesthetics but also for driver comfort and safety. Traditional ambient lighting modules often face challenges such as bulky designs, insufficient brightness, and inefficient heat dissipation.

Brightek's LIN-Lite Smart LED directly addresses these pain points, delivering a breakthrough in optical performance, compact integration, and thermal control.

By combining high-brightness LEDs with a built-in LIN driver IC inside an ultra-compact package, LIN-Lite Smart LED simplifies interior lighting architectures while enhancing brightness, ensuring color consistency, and improving system efficiency. The result is reduced wiring complexity, lower costs, and scaled-up performance for next-generation automotive ambient lighting.

What Is LIN-Lite Smart LED?

LIN-Lite Smart LED (also known as LIN-Lite ICLED) integrates ultra-bright LEDs and a LIN 2.x–compatible driver IC into a compact 6.5 × 4.5 × 0.85 mm package.

Unlike conventional setups requiring separate LEDs, drivers, and multiple PCB connections, LIN-Lite ICLED offers a streamlined architecture that reduces components, saves board space, and minimizes power loss — all while maintaining exceptional optical performance.

As a System-in-Package (SiP) component, LIN-Lite combines a high-brightness LED and driver IC into one miniaturized package. Its built-in pre-calibration process dramatically shortens production time and streamlines RGB LED color tuning. With the integrated driver, LIN-Lite can ensure stable brightness under varying thermal conditions. Supporting the LIN 2.x communication protocol, this intelligent LED enables smarter control and plug-and-play scalability.

Beyond its technical innovation, LIN-Lite ICLED delivers clear business value for automotive OEMs and Tier 1 suppliers by enhancing efficiency, lowering costs, and ensuring long-term reliability.
