Radical energy efficiency and creating a platform for distributed building intelligence
About Digital Lumens
Founded in 2008 by a team of engineers and entrepreneurs, Digital Lumens carved out a niche in the industrial internet of things (IIoT) sector. The company originated from research conducted at the Massachusetts Institute of Technology (MIT). The founding team included Brian Chemel, who brought his experience from developing network protocols and managing engineering teams, and Dr. Colin Piepgras, whose background lies in electrical engineering and power electronics. In 2017, the German lighting giant OSRAM acquired Digital Lumens, integrating it into its portfolio of digital lighting and IoT solutions. This acquisition provided Digital Lumens with substantial resources and a global platform to expand its market reach. Following the acquisition, the company continued to operate as a distinct brand within the OSRAM ecosystem, eventually becoming part of ams OSRAM. Digital Lumens provides intelligent lighting systems and IoT sensors for industrial and commercial facilities. The company’s primary offering is SiteWorx, an IIoT platform that combines lighting, sensors, and software to gather and analyze data from the physical environment. This platform is designed to help facility managers and operations leaders improve safety, optimize processes, and reduce energy costs. The system utilizes a network of smart LEDs and various sensors that monitor conditions such as occupancy, temperature, humidity, and power consumption. This data is then processed and visualized through the SiteWorx application suite, offering actionable insights for facility management. The business model revolves around selling this integrated hardware and software solution to clients in sectors like manufacturing, warehousing, and logistics. Revenue is generated through the sale of the physical lighting and sensor hardware, coupled with recurring software and data service subscriptions for the SiteWorx platform. The key benefit for clients is a significant reduction in lighting-related energy consumption, often by as much as 90%, alongside the operational intelligence gained from the environmental and operational data collected by the sensor network. This dual value proposition—energy savings and data-driven insights—forms the core of its market positioning.
