Unlocking efficiency, comfort, and sustainability through intelligent lighting control. Discover the trends and research shaping the future of smart buildings.
A Lighting Management System (LMS) is a sophisticated network of hardware and software designed to provide intelligent control over a building's lighting. It enables customizable programming, interconnectivity of all lighting devices, and communication for enhanced functionality and efficiency. LMS are evolving from mere illumination control to valuable sources of building operational data.

Reduction in electrical overheads with LEDs & advanced controls. (Source: LMS Report, Sec 1.2)
Optimal visual environments tailored to tasks, improving morale and well-being. (Source: LMS Report, Sec 1.2)
Centralized remote control, asset tracking, and predictive maintenance simplify building management. (Source: LMS Report, Sec 1.2)
LMS offers precise control over lighting, from individual fixtures to entire zones, and enables dynamic environments through scenes. This granular control is key to optimizing both energy use and occupant experience.
Addressable systems allow each light to be controlled independently, while zone control groups fixtures for simpler management of larger areas. Modern LMS often use software-programmable zones for flexibility. (Source: LMS Report, Sec 2.1)

Protocols like DALI and KNX are the languages LMS components use to communicate. DALI is lighting-specific, while KNX is a broader building automation standard. Gateways often bridge these systems.
| Feature | DALI (Digital Addressable Lighting Interface) | KNX (Konnex) |
|---|---|---|
| Primary Focus | Lighting-specific control | Full building automation |
| Device Limit (Typical Line) | ~128 (DALI-2) | Up to 256 (line), ~57,000 (system) |
| Key Strength | Granular luminaire control & diagnostics | System integration, scalability |

Building Management Systems (BMS) provide centralized oversight for LMS, integrating lighting with other building services. Intuitive Human-Machine Interfaces (HMIs), including synoptic displays (graphical maps), allow for effective monitoring and control.
BMS enables data processing, visualization, alarm management, and historical logging for strategic decision-making. (Source: LMS Report, Sec 4.1)
LMS employs various strategies to drastically cut energy use. Accurate monitoring, often down to the fixture via DALI-2, is crucial for verifying savings.
Adjusts electric light based on natural daylight. Significant savings in perimeter zones. (Source: LMS Report, Sec 5.2.1)
Illustrative savings potential.
Lights on when presence detected, off when vacant. Savings vary by room type. (Source: LMS Report, Sec 5.2.3)
Illustrative savings range.
Other key strategies include **Task Tuning** (setting appropriate max light levels, saving 20-36%), **Scheduling** (time-based control), and **Demand Response** (reducing load during peak utility times). (Source: LMS Report, Sec 5.2)
KPIs are vital for evaluating LMS performance in energy efficiency, light quality, operations, occupant satisfaction, and financial returns. (Source: LMS Report, Ch 6)
