ENGINEERING CAPABILITIES

Work That Speaks for Itself

This page provides an overview of Lighttower's technical capabilities and shows, through selected projects, how they are applied in practice. They cover the entire path from initial design to commissioning. Rather than isolated specialist services, this creates a continuous development chain without friction at the handovers.

Test System Development

Optical Spark Plug Test Bench

Optical Spark Plug Test Bench

Development of an experimental laboratory system for the optical investigation of spark formation under defined pressure, temperature and flow conditions. The system enabled reproducible experiments by combining optical diagnostics with conventional measurement techniques to support combustion research.

The principal engineering challenge was the development of a closed-loop flow circuit capable of providing defined flow, temperature and turbulence conditions at pressures of up to 50 bar while maintaining unrestricted optical access for diagnostic investigations.

Rapid Compression Expansion Machine

Rapid Compression Expansion Machine

Integration of an experimental test facility for investigating ignition and combustion processes under controlled pressure and temperature conditions. The system enabled highly repeatable investigations of combustion phenomena and supported the validation of simulation models.

By decoupling individual thermodynamic parameters, the facility made it possible to isolate specific effects that are difficult to separate in a running engine. This allowed fundamental combustion mechanisms to be studied under clearly defined and repeatable boundary conditions.

Thermal Simulation

Development of numerical simulation models for predicting engine warm-up behaviour under various operating conditions. The simulation supported engineering decisions by evaluating thermal concepts before experimental testing and enabled a deeper understanding of transient heat transfer mechanisms.

The models were calibrated against measurement data to ensure predictive accuracy across the relevant temperature range. This made it possible to assess design variants quickly and cost-effectively, reducing the number of physical test iterations required.

High-Power Probe Card Platform

High-Power Probe Card

Development of a next-generation probe card platform for high-current semiconductor applications. The work combined precision mechanics, thermal considerations, electrical integration and manufacturing aspects into a robust product suitable for industrial deployment.

A central challenge was managing high current loads and the resulting thermal effects while maintaining tight mechanical tolerances and contact accuracy. Material selection, thermal management and mechanical design were developed in parallel and validated through measurement to ensure reliable performance under demanding operating conditions.

The result is a scalable platform concept, engineered from the outset for repeatable series production rather than a one-off prototype.

Measurement Data Analysis

Development of customized workflows for analysing complex measurement data and transforming raw results into meaningful engineering insights. Advanced signal processing, visualization and statistical evaluation supported technical decision-making, model validation and continuous product optimization.

Automating recurring analysis steps significantly reduced manual effort and minimized sources of error in the evaluation. This ensured consistent, traceable results and allowed engineering conclusions to be drawn faster and with greater confidence.
