The DALI Alliance (DALI), the TALQ Consortium (TALQ), and the Zhaga Consortium (Zhaga)–each focused on defining international lighting standards to ease investment decisions for public and private entities–recently announced the signing of a liaison agreement to collaborate on unifying data streams for smart street lighting systems. The collaboration aims to provide a better choice of solutions with interoperable components and enhance communication across outdoor lighting systems.
DALI focuses on developing and managing digital lighting control specifications based on the IEC 62386 standard, enabling the widely recognized DALI-2, D4i, and DALI+ certification programs. Their commitment to interoperability and certification ensures that lighting components and systems can seamlessly integrate and communicate.
TALQ has developed and introduced a globally accepted standard for outdoor lighting systems using a standardized interface protocol for heterogenous outdoor device networks. The standard has also more recently been widened to include other smart city applications, like waste management, smart traffic, parking and environmental sensing. The TALQ Smart City Protocol enables consistent data to be used within smart city device networks and with the central management systems of cities and communities.
Zhaga, well-known for its work in creating interface specifications for LED light engines and sensor and communication modules, ensures compatibility across different manufacturers. By enabling interoperable LED components and their certification, Zhaga has helped to foster innovation and flexibility within the LED lighting industry.
The collaboration between these three organizations aims to streamline the exchange of data further, offering a unified approach for end-to-end communication and control in smart street lighting applications. The joint work will include a shared approach to achieving a unified data stream solution and exchanging visions on the requirements and architecture needed for such systems. This liaison will enable the respective specifications of DALI, TALQ and Zhaga to reflect the data and control requirements of outdoor lighting control systems.
This liaison signals a significant move towards aligning global standards in smart outdoor lighting. By creating interoperable solutions, the collaboration aims to reduce complexity for manufacturers and cities alike, ultimately fostering a more sustainable and efficient urban future.
