Enabling home and building automation

The digitization of buildings is continuously progressing, leading to increased comfort and safety, more security and less energy consumption. Combined lighting and sensing technologies are key enablers for a broad range of automated functions, like more differentiated smoke detection, smart keyless access, advanced human-centric lighting (HCL), UV-C treatment and condition monitoring or predictive maintenance for fail-safe operation of critical infrastructure and equipment.

Advanced access control and reliable monitoring solutions are crucial for security in buildings and sensitive working environments. Our key 3D technologies allow for secure authentication via facial recognition as well as security access to buildings or company car parks. ams OSRAM delivers effective solutions on all three forms of 3D sensing technology: active stereo vision (ASV), time-of-flight (ToF), and structured light (SL). 

We make light work in the workplace or at home with our smart lighting solutions at highest quality and efficiency. Our unique portfolio includes innovative LEDs  alongside spectral and ambient light sensors to tune the lighting impression.  Sensors for advanced presence detection help to reduce overall energy consumption. The combination of LEDs and sensitive photodetectors can also be used to pass information between smart luminaires for functions such as redundant alarm forwarding.

Finally, advanced projection technology using dynamic or static light patterns allow for traffic steering or occupation dependent routing in parking areas or office buildings to avoid congestions. Complementary marking of emergency escapes unlock a complete new set of possible use-cases for this technology. ams OSRAM provides the right fit product portfolio of emitters with broad selection of spectrum options as well as sensors for spectral, ambient light, position, presence, capacitive and even temperature sensing. Our portfolio offers endless design possibilities, greater cost efficiency, outstanding performance and highest accuracy.

Reliable smoke or flame detection

New optical technology for smoke alarms detect fire faster and more reliable – which helps to save lives and avoids false alarms binding precious resources at the wrong spot. The combination of a multi-spectral sensor and white LED emitter recognizes the unique spectral signatures of different types of smoke. The new technical concept to the design of next-generation smoke detectors has been developed and tested by ams OSRAM: We enable faster and more precise detection of hazardous situations caused by smoke or fire than other smoke detector on the market today. It also has the unique ability to distinguish between different types of fire and smoke, leading to more accurate alarms and less alarm artefacts due to, for example, dust. With the ams OSRAM technology, the emergency signal to first responders can now include information about whether the flame is from wood, plastic, oil, or some other material, so they can prepare the correct safety and extinguisher resources en route.  

ams OSRAM has the most complete portfolio in the market for emitters, photo-detectors and integrated sensors covering physical (e.g. optical, efficiency etc.) and certification (e.g. UL etc.) solution requirements. Our broad multi-spectral sensor offering and technology know-how, combined with broad process ownership across all portfolio options, drives innovative next-generation detector solutions. ams OSRAM’s market-proven components with highest quality and reliability paired with long-term component availability, provide our customers with the reassurance of a single point-of-contact for on-demand customized design integration and assembly options beyond standard components.

Secure access control

Advanced sensing capabilities have been used to enable biometric access solutions in the past. Most prominent are biometric face scans, iris scans, or fingerprint- / hand-print scans. Emerging recently are solutions around unique cardiac patterns or palm vein scans are being evaluated. Let’s take a closer look to the state-of-the art solutions first.

Biometric face scans typically capture the following features which are then compared for size, thickness, placement, shape or contour: cheek bones, eyes, nose, mouth, lips, chin and jaw line, forehead and scalp, ears. Critical infrastructure requires 100% biometric match whereas for most commercial systems a 80-90% match is sufficient. Protection against spoofing or faking (e.g. putting a photo in front of the scanner instead of real person) require true 3D face data capturing. For doing so, either dual-camera stereovision or single camera structured light scanning (where a single camera measures the shift of defined dot pattern projection) are being used.

Another biometric scanning approach uses iris scans. Each person has a unique iris in texture, size and color. A combination of near-infrared or visible light illuminators plus a digital camera are at the core of biometric eye scanning system. Typical distances between iris and scanning system are ~8-40cm. Iris scanning is among the most secure scanning technologies as it uses up to 240 reference points for deciding on a match (in comparison finger scans typically rely on ~60 reference points for a match).

Finally, finger-print- / hand-print readers scan the tiny friction ridges on the ends of fingers and thumbs, which are unique for each person. The scan can be performed optically (fast but sensitive to dirt), capacitively (fast but sensitive to wet or dirty hands) or using ultrasonic (even 3D scan, but slow). Irrespective of the scanning method, a map of the friction ridges is created which is evaluated during access scanning. Optical scans are typically about 512x512 pixel for a ~2.5cm2 image at ~500dpi and 256 grey shade levels. Live finger detection algorithms are deployed to detect fake fingers which the follow the same methods as known for vital sign monitoring: heart rate, blood oxygen etc. 

For all of the different scanning approaches, including vital sign monitoring, ams OSRAM provides a broad offering of illumination solutions, ranging from flat -side- looking LED devices, extremely thin and low- power backlighting LEDs to new-infrared laser solutions for flood illumination and dot pattern projection. On the sensing side, different imager options, ranging from 0.5 to 2.2Mpixel resolutions, are available; some include integrated low-power wake-up modes for best possible energy saving. If implementing full 3D sensing is too complex, anti-spoofing can also be implemented using ams OSRAM’s latest generation of multi-zone time-of-flight proximity sensors which are suitable for efficient presence detection methods.

Human centric lighting for favorite spaces

Human centric lighting is the discipline of creating lighting environments similar to which our bodily functions are used to from natural daylight. It enhances human performance, comfort, health and well-being. 

The most obvious effect of light on humans is vision. It enables us to identify brightness, shapes, colors, images, and perceive information and contrast. But there is much more to it: light also impacts our biology. It affects our hormones, alertness, attention and fatigue, and also determines our body clock and circadian rhythm.  
Photosensitive retinal ganglion cells (ipRCG’s) inside the retina form a neural pathway to the brain’s hypothalamus region. Our brain regulates the circadian (circa-daily) rhythm of the body following the natural day/night cycle. Melanopic light is the part of light spectrum with highest alertness potential, with a peak in ~470-490nm spectrum range. It triggers a photosensitive protein, so called melanopsin, inside the ipRGC’s. In a complex process, melanopsin suppresses the sleep-inducing hormone melatonin during the day and gradually increases melatonin production as light fades into night. 

Clinical studies have also unveiled that red light in mid-600nm and near infrared spectrum @ ~850nm helps to protect against age related vision loss - so called macular degeneration -  without any observed negative side effects. The stimulation of adenosine triphosphate (ATP) production by the mitochondria within the eyes’ cells counters the normal cell degradation, reduces visual decline, edema and hemorrhaging as well as risks of eye inflammations.

Finally light, especially in the UV spectrum, influences the Vitamin D production, endorphine release and direct immune suppression within the human body via the skin. Human centric lighting considers these effects and provides a holistic approach to lighting for humans. It balances the visual, emotional and biological needs of humans within lighting applications.

ams OSRAM provides a broad range of innovative LEDs across the full spectrum as well as spectral and ambient light sensors that form the backbone for any HCL solution. Our LEDs offer infinite lighting and design possibilities, and combine with our smart lighting mangers to create more cost-effective, higher accuracy selectable and tunable lighting, transforming spaces and enable a new level of light induced well-being. Our spectral and ambient light sensors make room-monitoring systems smart, able to always provide the right amount of light at the right spectral distribution. As lighting always benefits from energy saving, our low-power and high-efficacy LEDs can be complemented with smart presence detection sensors activating luminaires only when people are present in the room.
