Siemens aims to boost implementation of human centric lighting

 

Siemens Smart Infrastructure said it has certified three building products for the DALI-2 communication protocol to boost interoperability of human-centric lighting systems.

In a release, the firm said that the 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 DALI-2 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 human centric lighting (HCL) applications also in multi-vendor environments in order to increase concentration, productivity, and well-being indoors, the company said.

?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,? Siemens said.

?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,? Siemens added.

The German company said that 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, the firm explained.

Siemens Smart Infrastructure has recently completed the acquisition of French startup Wattsense, a hardware and software company which offers a plug-and-play IoT management system for small and mid-size buildings.

Siemens said that the acquisition will expand the firm?s building products portfolio. Wattsense was started in 2017 and is headquartered in Dardilly, near Lyon, France.

Wattsense optimizes the technical management of small and mid-size buildings with an IoT solution that enables the adoption of energy management practices in facilities with little or no building management system technology.

Siemens also noted that Wattsense allows customers to connect a wide range of devices and make them IoT-enabled. Multi-protocol devices can be onboarded easily before being connected to the cloud and operated in a Software as a Service (SaaS) model, the company said.

Siemens Smart Infrastructure has more than 2.3 million devices connected to its cloud platform. The business has more than 150 digital applications and offerings within its portfolio.
