Human-centric LEDs help energize or relax
Samsung Electronics has released its first “human-centric”
LED packages, LM302N, engineered with carefully created light
spectra to help human bodies adjust melatonin levels indoors,
making people
feel more energetic
or relaxed
depending on their
daily life patterns.
Brighter cyan-concentrated
lighting
suppresses the
body’s production
of melatonin,
increasing concentration and enabling a greater overall sense
of alertness. Similarly, a lower cyan light intensity minimizes
disturbances to the natural onset of the body’s melatonin production,
helping to promote sleep quality. Samsung’s LM302N
utilizes precisely designed light spectra with optimized
amounts of cyan to accommodate lighting needs to the extent
desired at any given point in time: the LM302N DAY improves
alertness and the LM302N NITE enhances relaxation. Standardized
at 3.0×3.0mm, these offerings can fit in a wide range
of lighting fixtures and are protected against humidity and heat.
The LM302N DAY can suppress the body’s melatonin level
more than 18 percent below that of conventional LED lighting,
the company claims. Available in a variety of colour temperatures
from 3000K to 6500K, the DAY package can be used in a
diverse range of indoor applications, such as schools, offices,
libraries and industrial sites, to enhance an individual’s sense
of awakeness and energy level. The LM302N NITE can provide
a proper level of brightness without hindering the release of
melatonin, helping people to maintain the hormone level as if
they were in a calm natural atmosphere at night. The LM302N
NITE is offered in colour temperatures between 1800K and
4000K. The DAY and NITE packages can also be combined
into a single luminaire to help people maintain their natural
circadian rhythm 24 hours a day.

OptoASIC switch system supports 25.6Tbps
In collaboration with Accton, Molex, TE Connectivity and other
leading industry partners, Rockley Photonics has developed
a so-called in-package-optics platform, the 25.6T OptoASIC
Switch system
co-packaged
with Rockley’s
LightDriver optical
engine and
copper cable
attached 400G
modules. Rockley’s
LightDriver
optical engine
has been developed using the company’s silicon photonics
platform enabling 3D integration of electronic and photonic
components. It delivers 40% savings in power and 60% savings
in cost vis-à-vis transceiver-based optics. The LightDriver
technology is scalable from 0.8T to 3.2T allowing Rockley to
address system solutions from 25.6T to 51.2T using 100G
PAM4 signalling. The switch system incorporates Molex’s
BiPass/TGA (Twinax Grid Array) copper interconnect system
and Samtec’s Si-Fly copper solutions. Accton has integrated
the MAC ASIC, optical engine, and copper connectors within
a Kyocera substrate, which is connected by an XLA socket
from TE Connectivity. Additionally, the demonstration switch
platform introduces Vicor’s vertical power GCM device.

3D profile inspection trained
at the push of a button
The smart EyeSens 3D Profile Inspector allows the singlebutton
training of various profiles. Therefore, the profile can be
inspected
for correctness
with repeatable
accuracy.
Most applications
can be
realized in the profile production field. EyeSens 3D Profile runs
completely without a PC, as the evaluation is carried out on
the sensor. The included DualSpeed CPU board is available as
800 MHz or 1.6 GHz variation with Dual Core and open FPGA,
which the user can program themselves with the included IPCore.
The integrated EyeVision Software also includes readymade
applications such as e.g. the Bent-Sensor, Glue-and-
Seal-Sensor, Gap-Sensor, WeldSeam Sensor, and many more.
The application, as well as the evaluation runs on the sensor,
without a PC. Thanks to the integrated EyeVision software the
PC-less EyeSens 3D Profile Inspector has a Profinet interface
to connect the system easily to a PLC. Further communications
interfaces such as Modbus, TCP/IP, UDP, etc. are also
available. Also, an OPC UA communication with a SCADA
system is possible.

UVC LEDs target water and air sterilization
Everlight Electronics’ ELUC3535NUB series of UVC LEDs emit
at 280nm from a 3.5x3.5x1.4mm footprint, packaged in inorganic
quartz glass.
The product series covers three different
intensity levels (2mW, 10mW
and 30mW), which makes it suitable
for various different applications
like medical treatment, water or air
purification and sterilization of germs,
viruses or mold. Furthermore, the
ELUC3535NUB LEDs can be used for
deodorizing and bactericidal treatment,
when installed for instance in a modern smart toilet. A
similar effect can also be achieved by using the company’s
UVA3535 (1.8W, 120º) LEDs in combination with titanium
dioxide.
