Steve Mesh Talks Luminaire-Level Lighting Controls

by 2 Comments

“Luminaire-Level Lighting Controls” (LLLCs) – this relatively new term in the lighting controls industry indicates that every fixture controlled by a networked lighting control system (NLC) incorporates two specific things: 1) a “controller”, and 2) sensors. This article by Steve Mesh describes the utility and application of this control approach, which is starting to be adopted by model energy codes.

Controlling Emergency Lighting

The LED revolution produced many luminaires with built-in switching and dimming. This facilitated a trend of using the same luminaires for both general and emergency lighting, powered by battery, backup generator, or UPS. This eliminates emergency units but creates a control challenge. The dual-function luminaires must be controllable for energy management and visual needs, while overriding these inputs to power to full brightness during a power failure.

Steve Mesh on Control Protocols

Steve Mesh writes, “According to Wikipedia, a communication protocol is a ‘system of rules that allow two or more entities of a communications system to transmit information via any kind of variation of a physical quantity.’ That’s a mouthful! What does that mean in terms of networked lighting control (NLC) systems?”
