UL Helps Advance LED Lighting Innovations
UL, a leading global safety science company, today announced that its lighting laboratory in Carugate, Italy, located in metro Milan, has received accreditation from the Digital Illumination Interface Alliance (DiiA) to be a Digital Addressable Lighting Interface (DALI) protocol test house. As an…
DALI, as a recognized industry-standardized protocol, is specified in the international standard IEC 62386, as well as by new specifications written by DiiA, including DALI-2. DALI-2 is the second-generation protocol based on the 2014 restructuring of the IEC 62386 standard that included the addition of application controllers and input devices.
With the DALI-1 registration requirements ending Dec. 31, 2019, new specifications in DALI-2, including bus timing and bus power, the interoperability between multiple vendors is improved. Other new DALI-2 specifications include polarity insensitivity that enables easier installation with less wiring needed for bus-powered units, an extended fade time – from 100 ms to 16 minutes – that increases flexibility for the end user and a query of the light-source type that enables easier maintenance. UL DiiA-accredited tests are now accepted as part of the DALI-2 certification process that are required prior to DiiA certification, which helps ensure multi-vendor interoperability and ultimately increase user acceptance.
In addition to the new DALI-2 testing specifications, UL's lighting laboratory in Carugate together with their UL colleagues from Basingstoke, England, which is a certified testing partner for Zigbee, Thread and Bluetooth® technologies, is now offering interoperability testing of wireless connectivity. Ahead of upcoming, anticipated DALI wireless specifications, the testing focuses on an application gateway solution to Zigbee and the use of Thread and Bluetooth® as an underlying wireless carrier to establish a DALI-2 end-to-end communication.
Roberto Inclinati, global senior business development manager of UL's Lighting division said, "UL is excited to be a key part of the growth and safe adoption of new LED innovations that help fuel the lighting industry globally. This new DiiA accreditation equips us better to support companies bringing new LED technologies to market and meet regulatory requirements that help fast-track their project fulfillment."
