ams and osram innovative automotive demos gathered at aee 2024

The first integrated pixelated LED contains 25,600 independently controllable light-emitting chips. It has the advantages of high luminous flux, high luminous efficacy, and balanced energy consumption. It can efficiently achieve higher brightness and color uniformity, bringing the safety and lighting effects of automotive headlights to a new level.

In addition to the conventional high and low beam functions, it can also realize high-resolution glare-free adaptive high beam (ADB), lane keeping assist warning, and road projection of warning signs (as shown in the on-site demonstration picture ↓) .

ams OSRAM’s ALIYOS™ LED-on-foil technology creates unprecedented effects in automotive lighting.

ALIYOS™ LED-on-foil technology breaks the boundaries of multi-zone lighting and enables customization of light emission patterns. Thin, transparent, 2.5D flexible and higher dimensional design freedom are achieved.

ALIYOS™ LED-on-foil technology can be combined with the curved surface materials of the car body in a new configuration to create customized multi-zone lighting and form a hidden light source design.

The SYNIOS® P1515 series makes it easy to achieve a smooth appearance and uniform light effect in applications such as extended light bars and automotive rear lights.

By replacing conventional top-emitting LEDs with SYNIOS® P1515 side-emitting LEDs, extremely high uniformity can be achieved at the same optical stack depth as top-emitting LEDs, while significantly reducing the number of LEDs and LED drivers.

Using the same number of SYNIOS® P1515 LEDs as top-lit products, combined taillights or turn signals can achieve thinner and simpler optical component designs, thereby enabling innovative combined taillight designs and creating eye-catching and unique shapes.

The ECE standard (UN R128) compliant LED signal light platform provides a standardized interface for lamps, which can easily switch between modules from different suppliers and is expected to bring economic benefits through standardized mass production.

This product has been standardized for automotive use and is not only available as a highly reliable off-the-shelf product, but also ensures long-term stable supply to enhance supply chain security.

In addition, ams OSRAM has a range of advanced product portfolios necessary for automotive lighting, including standard LED light source modules including red/amber/white modules for signal lights and white modules for headlights (fog lights).

As backlight strips, animation effects and other features enhance the cabin design, the ambient lighting system is being given a new mission.

Using intelligent technology, dynamic mood lighting is seamlessly integrated with the human-machine interface to create atmosphere, convey information, issue warnings, and other functions. Realizing these functions requires advanced intelligent RGB LED technology and a communication protocol that is compatible with the standard serial interface of various microcontrollers and can transmit high-frequency control signals.

The Open System Protocol (OSP) developed by ams OSRAM is a simple, open network technology designed for the interconnection of various devices such as LED lights, sensors, actuators, etc. in the car cabin. The protocol allows the control of up to 1,000 LED nodes through a daisy chain topology and is free for any LED light or other device manufacturer to use without the need for licensing or paying royalties.

ams OSRAM has launched its first two products for the OSP ecosystem: the smart RGB module OSIRE® E3731i, and the standalone smart driver (SAID) AS1163 (see below for details).

The OSIRE® series offers individually addressable LED chips, allowing extreme flexibility in color point, driver selection and interconnection for cabin mood lighting.

The small form factor of these products makes them ideal for connection with thin light guides to achieve ultra-compact designs. At AEE 2024, ams OSRAM demonstrated a dynamic lighting demonstration equipped with hundreds of smart RGB LEDs OSIRE® E3731i .

The AS1163 SAID (Standalone Intelligent Driver) is a mixed-signal IC designed for dynamic lighting applications. The AS1163 integrates nine output drivers to drive three RGB LED channels with a single chip. Each driver has an independent PWM dynamic range with up to 16-bit resolution (equivalent dynamic range).

Like the OSIRE® E3731i, the AS1163 also supports the OSP bus (Open System Protocol) for data communication. Due to their compatibility, the AS1163 can work perfectly together with the OSIRE® E3731i LEDs in the same application. In addition , the AS1163 supports parallel operation of up to 8 OSP daisy chains, making it possible to implement complex dynamic lighting schemes more flexibly and economically.

To ensure safe operation of the LEDs, the AS1163 can perform current/voltage measurements on individual LEDs and can be used as an I²C gateway. For this purpose, I²C ICs (I²C sensors, I²C actuators and I²C memories) can be connected to the SAID and addressed via the OSP bus.

ams OSRAM edge-emitting laser diodes (EEL) use innovative technology to achieve a lower wavelength temperature drift coefficient. As a result, LiDAR manufacturers can use narrower bandpass filters at the receiver (RX), which can significantly improve the signal-to-noise ratio (SNR).

Both ams OSRAM’s simulations and market feedback indicate that an improved signal-to-noise ratio can help increase the ranging range by up to approximately 40%.

At the exhibition, ams OSRAM also demonstrated this innovative technical solution, allowing users to intuitively experience its stability compared to traditional technical solutions.

In the future non-fully autonomous driving stage, a variety of driver monitoring functions will be needed, such as hands-off detection (HoD).

The ams OSRAM capacitive sensor AS8579 uses I/Q phase modulation technology to perform separation of the resistive and capacitive parts (quantity/share/ratio) of the impedance measured based on the sensor element.

This technology can more reliably detect whether the driver's hands are on the steering wheel, even when wearing gloves or in wet conditions. This means that the AS8579 can help automakers improve the safety of advanced driver assistance systems (ADAS) while reducing the cost of hands-on detection systems: the AS8579 can sense the impedance of the steering wheel heater element, while similar capacitive sensing systems for hands-on detection require dedicated metal sensor elements built into the steering wheel .
