Why does Hebatronic not offer LIN-based solutions?2026-01-29T16:00:37+01:00

Hebatronic deliberately does not offer LIN-based solutions because LIN is not technically suited for modern ILaS® / ISELED® lighting systems beyond basic control functions.

LIN was designed as a low-speed control bus for simple actuators and sensors. With a maximum data rate of approximately 20 kbit/s, LIN is well suited for commands such as on/off, dimming, or basic status signals. However, it reaches its technical limits very quickly when used for today’s dynamic, high-resolution LED lighting systems.

Modern ILaS® / ISELED® applications require:

  • High bandwidth for color and brightness data

  • Deterministic timing for synchronized animations

  • Scalability to hundreds or thousands of LEDs

  • Detailed diagnostic feedback at LED level

These requirements are structurally incompatible with LIN. Using LIN as a transport layer for ILaS® functions inevitably leads to compromises in performance, diagnostics, flexibility, and scalability.

Hebatronic therefore focuses on ILaS-native architectures, where lighting data is handled directly on the ILaS® bus and controlled via industrial, deterministic interfaces (e.g. PLC-based systems). This avoids inheriting the technical limitations of LIN and allows the full capabilities of ILaS® to be used without restriction.

In short:

  • LIN is suitable for controlling simple lighting functions.

  • ILaS® is required for driving complex, modern LED lighting systems.

  • Hebatronic designs its solutions around the requirements of ILaS®, not around the limitations of LIN.

This is a conscious architectural decision to ensure long-term scalability, diagnostic depth, and production robustness.

 

 

What is the difference between LIN and ILaS®?2026-01-29T14:48:52+01:00

LIN (Local Interconnect Network) and ILaS® (Intelligent Lighting as a Service) are two fundamentally different communication systems used in vehicles, each designed for a specific purpose.

LIN is a classic, low-cost control bus. It was developed for simple actuators and sensors such as switches, motors, and basic lighting functions. LIN operates at a relatively low data rate and is mainly used to transmit control commands like on/off, dimming, or simple status information.

ILaS®, in contrast, is a high-speed bus specifically designed for modern LED lighting systems. It is optimized for ISELED®-based light modules and transmits synchronized color and brightness data to each individual LED in a chain. In addition, ILaS® enables detailed diagnostic feedback from every LED.

In short:

  • LIN is a control bus for simple functions.

  • ILaS® is a data bus for complex, dynamic LED lighting.

Key differences at a glance:

  • Data rate:
    LIN ≈ 20 kbit/s · ILaS® ≈ 2 Mbit/s

  • Typical use:
    LIN → basic control commands
    ILaS® → high-resolution lighting data and animations

  • Scalability:
    LIN → limited number of nodes
    ILaS® → thousands of LEDs in a single chain

  • Diagnostics:
    LIN → basic
    ILaS® → detailed, per-LED diagnostics

In modern vehicle and EOL test architectures, both systems are often used together:
LIN provides the higher-level control or test interface, while ILaS® handles the precise distribution, synchronization, and diagnostics of the lighting system.

 

What is ILaS®?2024-11-18T17:18:12+01:00

ILaS® is a new fieldbus that can transmit various light sequences at a bus data rate of 2 Mbit/s, enabling video-speed control. ILaS® stands for “ISELED® Light and Sensor” and is currently mainly used in the automotive sector, particularly by BMW in vehicles starting in 2025. With this fieldbus, not only can LEDs be controlled via the ISELED protocol, but sensors and actuators can also be integrated and read in any quantity and combination. With the continuously growing number of LEDs, especially in vehicles, significantly higher data rates for control and diagnostics can be realized.

How is the ILaS®-Shield (ILaS®duino) operated?2024-11-18T17:27:14+01:00

The ILaS®duino is powered via USB or 12V. To do this, connect the ISELED®uino pins E_P, E_N, and Gnd to ILAS_H_IN, ILAS_L_IN, GND. The ISELED® lighting modules can be powered with external 12V, but it is essential to connect the GNDs together. On the ISELED®uino, all pins can be used except for A3, A5, and A6. These are the communication pins between the microcontroller and the ILaS®-Shield.
