With the ongoing evolution of digitalization, intelligent systems, energy conservation, and new energy trends, the automotive industry has undergone significant transformation. Automotive lighting has also progressed from traditional light sources to LED technology. Ams OSRAM has pioneered the integration of light and intelligence in the automotive lighting market, particularly in human-vehicle interaction. This integration has led to innovations in light sources and has driven the development of automotive lamps and an expanded range of possibilities.
As the Chinese automotive market transitions from a follower to a leader, new trends and demands are emerging, especially with the rise of electric vehicles (EVs). These trends include unique innovations in design and functionality. Ams OSRAM is keeping pace with these changes, having established a robust presence in China with numerous China for China and China for Global strategies, including innovations in product development.
Many cost optimizations stem from innovation. Key areas of focus for ams OSRAM in product innovation include: liberating designers’ creativity, enabling more creative design options, enhancing the flexibility of engineering architecture, offering consumers more choices, and providing emotional or interactive connections.
The Senior Marketing Manager of ams OSRAM, Luo Li, focused on several products from an innovation perspective during his presentation.
EVIYOS® 2.0: 25,600-Pixel Micro LED
Ams OSRAM’s latest offering, the EVIYOS® 2.0 with 25,600 pixels, is the first LED that combines light and electronics. Typically, LEDs are controlled by a CMOS circuit beneath the surface, enabling independent control of each of the 25,600 pixels. Each pixel is smaller than the diameter of a human hair (approximately 50 µm). This highly compact arrangement, with 25,600 pixels compressed onto a 40 mm² curved surface, is a remarkable achievement in the industry.
This 25,600-pixel EVIYOS® 2.0 can be used in a variety of visual applications, including welcome projections, lane change light carpets, lane-keeping assist warnings, and slippery road surface alerts.
Notably, the EVIYOS® 2.0 enables glare-free high beams. It smartly adjusts the high beam during driving to maximize the driver’s visibility, while recognizing and avoiding glare for pedestrians and vehicles, achieving active ADB (Adaptive Driving Beam) functionality.
After its launch, the EVIYOS® 2.0 has caused a stir in the automotive market. It also holds potential for expansion into other commercial and industrial lighting sectors, offering high-quality dynamic lighting solutions that balance power, size, weight, cost, and performance.
Smart Ambient Lighting: RGBi and OSP
The second product is ams OSRAM’s OSIRE® E3731i (Smart RGB or RGBi), a smart RGB LED product based on the OSP open architecture. Automobiles are increasingly becoming the “third living space” besides homes and offices. In these spaces, ambient lighting is essential for creating atmosphere, such as dynamic lighting in response to music, different driving modes, or even reflecting the driver’s emotional state.
These ambient lighting systems must address several challenges: (1) the increasing number of LED components; (2) balancing costs with quantity; (3) ensuring uniform and harmonious color mixing across different RGB suppliers. The OSIRE® E3731i addresses many of these challenges, ensuring seamless color transitions without delay or color distortion.
Moreover, these systems have complex back-end logistics. For example, a vehicle may contain hundreds of LEDs. Using traditional distributed architectures, each LED would require a separate driver, complicating future OTA (over-the-air updates). The OSP open architecture eliminates MCU manufacturer constraints and simplifies the wiring and connection process, allowing up to 1,000 RGBi chips to be connected with a single SPI interface. This facilitates intelligent connectivity between various car nodes and supports the integration of various sensors, offering a flexible architecture for future upgrades.
SYNIOS® P1515: 360° Radiating Side-Emitting LED
ams OSRAM’s SYNIOS® P1515 is an innovative side-emitting LED originally designed for automotive interior backlighting. As car interiors increasingly feature screens, there has been a shift from top-emitting to side-emitting backlighting. The SYNIOS® P1515’s unique 360° light emission design offers structural innovation, providing uniform light distribution around the LED package.
The SYNIOS® P1515 has two primary applications in automotive exterior lighting: First, as a replacement for traditional top-emitting LEDs. The 360° radiation feature allows for wider LED spacing, reducing the number of LEDs and corresponding drivers, thereby significantly lowering system costs. In one example, the number of LEDs was reduced by two-thirds, while still maintaining the same brightness and uniformity. Second, the SYNIOS® P1515 enables ultra-thin, uniform lighting to achieve OLED-like designs. Traditionally, such designs would require a depth of 20-30 mm; however, this innovative packaging reduces the depth to just 5 mm, enabling more compact and creative designs.
Additionally, the even light distribution and ability to create dynamic displays and pattern designs offer greater flexibility. By adjusting the light path between individual LEDs using grid spacing, a higher contrast ratio can be achieved, allowing for greater freedom in design and pattern creation.
