Lighting Design Explained: The Path to the Perfect Lighting Concept
What Is Lighting Design?
Lighting design is the systematic process of planning the illumination of a room or building to be functional, aesthetically pleasing and energy-efficient. Good lighting design takes into account the use of the space, the architectural conditions, the desired atmosphere and the technical requirements.
Light has many qualities. As an important part of our living environment, it significantly influences our well-being and biorhythm. The right lighting creates an atmospheric ambience, ensures a high level of visual comfort and can even help to make an interior appear larger. Not least, light plays a decisive role in showcasing architecture and interior design.
The Three Layers of Lighting
A well-considered lighting concept typically works with three lighting layers:
- 1. Ambient Lighting: Even base illumination for orientation and general brightness. Created by ceiling luminaires, indirect lighting or diffused light.
- 2. Task Lighting: Directed light for specific activities – reading, working, cooking. Realised through pendant luminaires above the dining table, desk lamps or under-cabinet kitchen luminaires.
- 3. Accent Lighting: Targeted light to showcase objects, artwork or architectural details. Achieved with spots, spotlights and picture lights.
The art lies in coordinating these three layers to create an impressive spatial effect – ideally without the light source necessarily being visible.
What Matters in Lighting Design?
Numerous factors come together when developing a lighting concept:
- Illuminance: How much light is needed? Measured in lux. The requirements vary considerably depending on the room's use – an office workstation requires at least 500 lux, while a living room can manage with 100–200 lux.
- Colour Temperature: Warm white, neutral white or daylight white? The choice of colour temperature significantly influences the spatial effect and well-being.
- Colour Rendering: How natural should colours appear under the lighting? A high CRI value (at least Ra 80, preferably Ra 90+) ensures natural colour rendering.
- Glare Control: Luminaires should produce pleasant light without causing glare. The UGR value provides information about the glare effect of a lighting installation.
- Dimmability: Flexible brightness adjustment for different usage situations – from focused work to a relaxed dinner.
- Energy Efficiency: Use of modern LED technology for low energy consumption with high light quality.
- Architecture and Room Geometry: Ceiling height, room proportions, window areas and surface materials all influence how light works within the space.
- Connection Planning: Particularly for new builds and renovations, early planning is essential to determine where which connections are needed – so that the right outlet is in the right place later on.
When Should Lighting Design Begin?
Lighting design should start as early as possible in the planning process – ideally during the design or shell-construction phase. The reason: many lighting solutions require prepared electrical installations that can only be retrofitted at considerable expense.
This applies in particular to:
- Recessed luminaires and ceiling spots that need to be accommodated in suspended ceilings or concrete ceilings
- Indirect lighting with LED strips in cove ceilings or niches
- Track systems that require a power rail on the ceiling
- Smart-home systems where the control technology should be factored in during the electrical installation
- Outdoor lighting, for which underground cables and junction boxes need to be prepared in garden and façade areas
Anyone who only thinks about lighting after moving in is often limited to the existing connection points. Early lighting design creates the foundation for maximum flexibility and a cohesive overall concept.

Lighting Design in 4 Steps
The process of professional lighting design at Leuchtenland.com follows a proven methodology:
- 1. Consultation and Analysis: In a personal discussion – by telephone, video call or on site – your ideas, the spatial conditions and the functional requirements are recorded. Floor plans, photographs and sketches help to build an accurate picture.
- 2. Concept Development: Based on the analysis, a lighting concept is developed that incorporates the three lighting layers and meets all technical requirements. For more complex projects, sample plans and 3D visualisations are produced.
- 3. Luminaire Selection and Quotation: From a broad range of designer luminaires – from timeless classics and modern lighting systems to expressive lighting objects – the right luminaires are selected and a detailed quotation is prepared.
- 4. Installation Support and Final Inspection: The lighting planners supervise and advise during final installation, coordinate the electrical contractors and ensure that the lighting concept is implemented as planned. For smart-home systems, the setup and programming of the lighting control is carried out.
3D Visualisation and Sample Planning with DIALux
To present lighting concepts vividly, the lighting planners at Leuchtenland.com work with the professional planning software DIALux. DIALux translates spaces into a computer-animated view and, by adding luminaires and lighting systems, produces a true-to-scale room simulation.
The 3D visualisation offers several advantages:
- A realistic impression of the planned lighting situation before a single luminaire is installed
- Lighting effects and moods can be explored and varied
- Illuminance levels and uniformity are verified by calculation
- Changes can be implemented without delay before costs are incurred
- For commercial projects, compliance with normative requirements (e.g. DIN EN 12464-1) can be documented
Computer-aided lighting design is suitable for indoor and outdoor spaces, for individual rooms as well as complete buildings. Particularly for more complex projects – offices, commercial premises, medical practices, hotels or entire floors – DIALux is an indispensable tool.
Smart Home and Lighting Control
A professional lighting concept only realises its full potential with a well-considered control system. Leuchtenland.com plans and integrates smart-home systems for lighting:
- Casambi: Bluetooth-based lighting control without a gateway, particularly popular in the design and residential sector. Leuchtenland.com is an experienced Casambi partner and handles the complete setup and programming.
