$2m prize in LED lighting prototype competition

Business news |
By Nick Flaherty

The US Department of Energy (DOE) has opened the Prototype Phase of its L-Prize competition, which seeks to boost innovation in advanced LED lighting fixtures and control systems for use in commercial and institutional buildings.

The designs will be based around the DALI D4i connectivity specification and Zhaga Book 20 with separate tracks for Luminaires and Connected Systems. Up to six winners will share a prize pot of $2m.

Zhaga was launched in 2010 as an open, global lighting-industry consortium to standardise the interfaces of components of LED luminaires, from LED modules to connectors and sensing/communication modules. In 2018 it shifted the focus towards interoperability via a series of specifications, or books.

Book 20, used in the L-Prize defines a smart interface between an indoor LED luminaire and a sensing/communication node. The node connects to the LED driver and control system, and typically can provide sensory inputs or enable communication between network components. Nodes can be installed and replaced in the field.

The DALI Alliance, the Zhaga Consortium and the Pacific Northwest National Laboratory (PNNL) will hold a webinar later this month to discuss the technical requirements of the Prototype Phase and explain the opportunities for entrants when using standards-based connectivity technologies including Zhaga Book 20 and D4i data and control.

Entrants must complete an Intent to Submit form by January 2023, and the submission deadline is May 1, 2023.

The webinar will take place on Thursday 15th September 2022 at 08:30 am Pacific time, 11:30 am Eastern time. with speakers including Gabe Arnold, PNNL Senior Engineer, who will describe the Prototype Phase and explain the entry requirements.

Scott Wade, Technical & Certification Manager with the DALI Alliance, will explain how the use of D4i drivers, sensors and communication modules will enable competition entrants to meet the requirements for addressability, energy reporting, diagnostics and fault reporting, and many other features.

Adrian Green of Amphenol, representing Zhaga, will describe how Zhaga Book 20 enables modules with occupancy and ambient light sensing capabilities to be directly installed into luminaires via standardized receptacles. The presentations will be followed by a Q&A session and the registration form can be accessed here.
