Correcting 0-10V LED dimming with digital drivers
Solid-state luminaires have taken the market by storm due to the amount of energy they save. LED luminaires use one-third the power of fluorescent lighting and less than half the power of incandescent lighting. Dimming capability can increase energy savings even more, while improving the work environment for tenants. But the problem is that 0-10V LED dimming is not truly standardized. If you mix and match LED luminaires from different vendors you will likely get different dimming profiles, which can really be a problem especially for lighting retrofit projects.

Two-way communications also ensures that luminaires perform as expected. Monitoring across the ecosystem provides information about luminaire characteristics, as well as the performance of other components in the system such as switches, panels, dimmers, and sensors. Remote diagnostics and maintenance often can be performed remotely using software commands sent over a wireless link. And by using open standards such as Bluetooth mesh for communications users aren’t locked into only one manufacturer’s proprietary system – no more limited programming options or expensive service contracts.

Digital LED dimming systems can be integrated into building management systems as well. Lighting is the most prevalent electrical system in any building and the same programmable LED drivers can be equipped with sensors to detect temperature, ambient light, and more. The two-way intelligent lighting control infrastructure can be extended to manage HVAC and other building systems. Automating building management could result in an additional 40 percent energy savings in addition to the energy savings from an LED retrofit. More advanced systems can even use the smart lighting infrastructure to track hardware using Bluetooth tagging, or to support for wayfinding, safety and security, and even quality control using various types of wireless beacons.

The first step, however, has to be intelligent digital drivers. With digital programmability, LED drivers can be configured to delivery consistent dimming characteristics, and by adding wireless connectivity you add an entire new dimension of capabilities and control.
