Press Release07 December 2021Smart InfrastructureZug
Siemens facilitates implementation of human centric lighting
New DALI-2 certification for Siemens Desigo PXC3 and KNX gateway N 141 as well as switch/dim actuator N525D11
Certification ensures interoperability in multi-vendor environments
Lighting based on circadian rhythm helps improve health conditions in indoor environments
Siemens Smart Infrastructure’s building products KNX/DALI gateway
N 141 and the switch/dim actuator 2x DALI Broadcast N 525D11 as well as the Desigo
PXC3 controller were recently certified under the new DALI-2 communication
protocol standard for lighting in buildings. DALI-2 is an update to the original
“Digital Addressable Lighting Interface (DALI)” protocol and facilitates
interoperability and control for LED drivers. The newly certified Siemens
products will help implement state-of-the-art human centric lighting (HCL) applications
also in multi-vendor environments in order to increase concentration,
productivity, and well-being indoors.
Moreover, such lighting applications seamlessly integrate
into holistic building automation systems provided by Siemens which combine heating,
ventilation, air conditioning, and shading. Customers can choose between
solutions based on either Desigo or KNX, according to their individual
installation requirements.

“Tunable white” functionality to imitate natural daylight
Dynamic color temperatures create a pleasant room
atmosphere and contribute to the occupants’ well-being. Designed to promote
this goal, the HCL concept for interior spaces specifies using the correct
color temperature and illumination at the right time. Following this approach, the KNX building automation products
from Siemens provide infinitely variable color temperature control thanks to the
“tunable white” functionality. This makes it possible to create any shade of
white light, from warm to cold, and allows easy implementation of daylight
simulations. In technical terms, the color temperature of the light
emitted by the luminaires is adjusted from approximately 2700K in the morning to
approximately 6500K at midday and then lowered again to 2700K in the evening.
By reducing the blue component of the light in the evening, the body is
prepared for the night ahead.
