Control units – lighting control at a professional level

When light not only shines, but thinks and reacts

Control units are the heart of modern lighting systems – they connect luminaires with intelligence, enable automation, scene control and efficiency, and integrate light into architecture and technology. Whether in offices, living spaces, shops, restaurants or commercial buildings: High-quality control units ensure that light not only illuminates, but also accompanies, structures and complements. At Licht-Kraus you will find only control units from leading manufacturers – state-of-the-art technology, safe installation and long-term usability.

A control unit doesn't just improve the function of a light fixture – it transforms a lighting system into a user interface. The following text provides comprehensive information on applications, technology, system compatibility, design & integration, energy savings, and maintenance. A detailed FAQ section is included at the end.

Function & Importance of Control Units in the Lighting System

Control units take over control tasks that were previously performed manually or by simple switches. They allow for automatic lighting adjustment, scene changes, and integration into building technology.

Tasks

• automatic light control depending on the time of day or usage

• Connecting lights to sensors or control wires

• Storage of light states and transitions

• Networking of lighting systems and building automation

Thanks to the control unit, light becomes flexible and intelligent – ​​no longer just static.

Technology & System Compatibility – High-End Lighting Management

Control units are part of lighting systems. Their selection determines how well luminaires, sensors, networks and control technology interact.

Technical features

• Interfaces such as DALI, DMX, Casambi, KNX or simple 1-10V control

• compatible with various lights and control components

• Programs for time control, presence/motion, daylight compensation

• Safety devices, protective circuitry and reliable electronics

This technology ensures that lighting control becomes professional – low-maintenance, efficient and future-proof.

Design integration & materials – technology in the background, light in the foreground

Good control units are usually invisible – but essential. The workmanship, mounting method, and choice of materials are more important than you might think.

Features

• Enclosure for surface or recessed installation in control cabinets or sub-distribution boards

• compact design, clear labeling, stable cabling

• good ventilation, protective lacquer or powder coating for long-lasting use

• Easy-to-install design: simple installation, clear accessibility

Technology should work – and remain almost invisible.

Application areas & planning – Control tailored to the use

Control units are used in many areas: from residential buildings to large-scale projects. Planning is crucial for their effectiveness and function.

Areas of application

• Office spaces with automation of light zones, daylight and presence

• Living and guest areas with lighting scenes for mood, ambient light, function

• Shops and exhibitions with changing lighting settings and scenes

• Exterior areas or architecture with lighting design, light lines or effects

• Special applications such as fire protection or safety lighting systems

Planning notes

• Analyze the number of lights, control circuits and sensors

• Interface selection (e.g., DALI vs. 1-10 V) according to room type and technology level.

• Carefully consider the mounting location of the control unit – maintenance, ventilation, access

• Compatibility with existing systems or future expansion

Energy saving & sustainability – lighting that pays off

Control units contribute significantly to energy savings – light is only used when it is needed.

Advantages

• Presence or daylight sensors prevent unnecessary light.

• Scene control reduces full load and travel times

• Intelligent shutdown and time programs save electricity

• Long service life thanks to good technology and low stress

This makes light not only more beautiful – but also more efficient.

Maintenance & long-term use – Investment in technology perspective

Control units are often underestimated. But good units pay off in the long run – through reliable operation and low downtime.

Care instructions

• Regular checks for dust, moisture, or cable damage

• Pay attention to firmware updates for intelligent systems

• Ensure proper ventilation – do not block devices with heat sources

• Keep contact persons and documentation for maintenance accessible

Technology remains in the background – the effect is created by the light.

Lighting design & technical understanding – control as part of the design

Control units are the link between the lighting concept and the luminaire. Those who take them into account elevate light from illumination to an experience.

Design benefits

• Light not just on/off, but scene, mood, structure

• Technology in the background, effect in the room

• Adaptation to person, usage and time of day

• Lighting systems instead of individual luminaires – intelligent and long-term

FAQ – Control Units

1. What is a control unit in the lighting system?
A control unit connects lights with sensors and control systems, enabling scenes, automation and networking.

2. What interfaces are available?
Common: DALI, 1-10 V, DMX, Casambi, KNX – depending on the application and level of technology.

3. Can control units be retrofitted?
Yes – provided cabling and technology are in place; planning and testing are necessary.

4. What potential savings do control units offer?
Very high – through shutdown when empty, use of daylight and scene control.

5. How long do professional control units last?
With good ventilation, clean operation and correct installation, many years – often over 10 years of use.

6. Do I need sensors with a control unit?
Sensors ideally complement the control unit – e.g. daylight or presence sensors for light control.

7. Can I use control units for smart home systems?
Yes – many devices offer interfaces for building control or app integration.

8. What should I pay attention to during assembly?
A location with good ventilation, accessible cabling, clearly labeled connections, and stable mounting.

9. Do I need to service control units?
Generally, very little is required – occasional checks are sufficient. Firmware updates are possible for intelligent systems.

10. What should I pay particular attention to when buying?
Technical interfaces, number of control circuits, compatibility with lights and sensors, future-proofing and quality.
