Our Light Simulation Services
From Virtual Simulation to Production-Ready Implementation —
Everything from a Single Source.
Your Light Simulation Project at ITB
As experts in light simulation, we offer comprehensive services for the development and optimization of light guides and optical systems.
Our competence and experience enable us to create light guide designs that account for both photometric and manufacturing-related factors, precisely tailored to the specific requirements of each project.
We rely on precise simulations and state-of-the-art software solutions to ensure the best possible lighting performance — from the initial concept through to production-ready design.
Light Simulation on Your Behalf
The following section describes the typical workflow of a light simulation project, from the initial brief through to results analysis. Depending on your scope and requirements, the process is flexibly adapted to individual needs.
1. Requirements Analysis
Joint definition of project objectives: luminous flux distribution, illuminance, and optical performance.
2. Data Collection & Review
Assessment of CAD and material data, ray files, and technical specifications.
3. Concept Development
Development of the simulation concept.
4. Modeling & Simulation
Building up of the optical model in LightTools / Ansys SPEOS and execution of the simulations.
5. Results Analysis & Optimization
Evaluation, design variant comparisons, and targeted design optimization.
6. Presentation & Documentation
Final review meeting, handover of all data and production-ready results.
- CAD models of the components or products
- Material properties and surface data
- Requirements for luminous flux distribution, intensity, and design
- Light source specifications (e.g., LED optical datasheet / name)
- STEP model of the light guide, designed ready for manufacturing
- Manufacturing guidelines for practical implementation
- Documentation of all steps, from requirements analysis through to the final result
- Through our close integration into your development process, you benefit from efficiency, transparency, and optimal results.
Simulation and Practice — A Holistic Approach
We Combine Simulation-Based Development with Practical Implementation.
Leveraging our high-performance computing capacity and specialized tools (e.g., LightTools), we model complex lighting conditions with a high degree of realism.
Our expertise allows us not only to compute simulation results, but also to evaluate them systematically and translate them into actionable insights for your product development.
Benefits of Light Simulation in the Development Process
The targeted use of light simulation optimizes development workflows and enables:
- Cost savings through virtual testing — fewer physical prototypes required
- More precise and higher-performing light guide designs through detailed analysis of light propagation, color fidelity, and scattering
- Faster time-to-market through reduced development iterations and early-stage validation
- Custom adaptation of optical systems to specific requirements
Technical Expertise and Solution Approaches
Our core competency lies in the development and optimization of light guides — from theoretical modeling through to practical implementation.
Our simulations enable targeted solutions to key engineering challenges:
- Optimization of luminous homogeneity and color mixing for single- and multi-color systems
- Reduction of glare and improvement of luminous flux distribution
- Efficient light extraction to maximize luminous efficacy
- Seamless integration of optical systems into existing product designs
Efficient Development Processes — From Concept to Prototype
Our light simulation services accompany the entire product development process — from the initial concept phase through optimization to production-ready implementation.
Thanks to our partner network, we offer not only precise prototype manufacturing for real-world validation of simulation results, but also access to experienced partners for series production.
This enables compelling design presentations, minimized development risk, and accelerated market readiness.
Light Simulation as a Key Technology
The targeted application of light simulation enables complex lighting solutions to be developed efficiently, precisely, and sustainably.
With a solid theoretical foundation, practical approaches, and the necessary technical infrastructure, we support the development of innovative lighting systems.

“For me, sustainability begins in development. With precise light simulations, we create the basis for energy-efficient, standard-compliant products – even in the digital design. My goal is to design this technology in such a way that small and medium-sized companies also benefit from it: affordable, practical, forward-looking.”
