KNX + DALI / Human Centric Lighting Engineering
IKNXUSA provides engineering guidance and system-design support for integrating KNX building automation with DALI and DALI-2 lighting control systems, including advanced architectural lighting and Human Centric Lighting (HCL) applications.
KNX and DALI serve complementary roles within a professional lighting-control architecture. DALI provides digital control and monitoring of compatible lighting equipment, while KNX provides the broader building-automation infrastructure that can coordinate lighting with occupancy, daylight, HVAC, motorized shading, energy management, visualization, schedules, and other building functions.
KNX + DALI System Architecture
A typical integrated system uses a KNX/DALI gateway to connect the KNX automation network with one or more DALI lighting lines.
Depending on the selected equipment and project requirements, the system can provide individual, group, broadcast, and scene-based lighting control while making lighting functions available to the KNX system.
Engineering considerations can include:
- KNX/DALI gateway selection and system architecture
- DALI and DALI-2 lighting design
- DALI addressing, groups, and scenes
- Dimming and switching strategies
- DT8 Tunable White and color control
- Occupancy and presence detection
- Daylight-dependent lighting control
- KNX switches, sensors, and user interfaces
- Lighting status and diagnostics
- Visualization and centralized supervision
- Emergency-lighting integration where applicable
- Coordination with HVAC, shading, and energy-management systems
Human Centric Lighting (HCL)
Human Centric Lighting extends lighting control beyond basic switching and dimming by dynamically adjusting the lighting environment according to time of day, occupancy, daylight conditions, space function, and programmed lighting strategies.
Using DALI DT8 Tunable White luminaires, for example, the system can control both light intensity and correlated color temperature (CCT). KNX can provide the higher-level automation logic, schedules, sensor information, user interaction, and coordination with other building systems.
A typical architecture may follow:
KNX Sensors & Controls → KNX Automation → KNX/DALI Gateway → DALI/DALI-2 → Tunable White Luminaires
This architecture can support automatic lighting profiles while still allowing appropriate local user control and manual overrides.
Architectural Lighting as Part of Building Automation
The objective is not simply to connect a DALI gateway to KNX. Effective lighting engineering requires coordination between the luminaires, drivers, control protocols, sensors, automation logic, user interfaces, electrical design, and intended operation of the space.
IKNXUSA Engineering helps professionals develop lighting-control architectures that combine KNX, DALI/DALI-2, Tunable White, HCL, occupancy sensing, daylight control, visualization, and building automation into an integrated system.
Design the lighting. Integrate the controls. Automate the environment.
