Smart City – The Future speaks D4i


City Lighting has gone through major developments over the last few years. What has been called a street light is nowadays data and sensor hub, tightly integrated with other parts of the  smart city infrastructure. What has been a simple, energy consuming light producing cost element (=a street light pole), has become a revenue generator and sensor hub as well as design element for the city.

Smart City Control Infrastructure

A core challenge in building such an infrastructure, is about how to interact with it. In the past, many of such infrastructures were controlled by using proprietary or semi-proprietary control systems, requiring substantial communication technologies investments and avoiding a standard-based interaction of best-of-breed technologies. The cities were bound to very few or even single provider solutions

The fast growth of IoT based standards is enabling cost-efficient and technology sound integration of Smart Street Lights. In particular the D4i extension of the popular DALI-2 standard has been the launching pad for a new range of possibilities and products.

What is D4i?

In short, D4i is the DALI standard extension, for IoT-ready luminaires. D4i drivers have a mandatory set of features related to power-supply requirements and smart-data capabilities. D4i luminaires are enabled to gather data from on-board and connected sensors, and provide data of the light – like performance, asset status, etc. – allowing preventive maintenance or other tasks. The D4i drivers is supporting different wired or wireless communication standards, providing the best flexibility for projects.
