Light simulation: Realistic analysis of optical systems and special lighting situations

Lighting simulation has proven to be an essential tool in the world of design and engineering. With the ability to precisely analyze and visualize complex lighting effects, lighting simulation enables users to make informed decisions about the design and functionality of lighting concepts.

Why use light simulation to analyze optical systems?

The analysis of lighting conditions using light simulation is of great importance in the design and evaluation of components and entire structures. It not only provides detailed insights into light distribution, but also enables optical design and functionality to be quickly modified and optimized. This saves time and costs compared to conventional methods and promotes innovation and design quality.

Accuracy of the simulation

The simulation enables a realistic representation of the structures to be examined. It is possible to examine other frequency ranges of light, not just the visible range of humans.

Increased efficiency and cost savings

The simulation allows different scenarios to be tested without having to make any physical changes. This saves time and resources that would otherwise be needed to build prototypes and carry out physical tests. Evaluation in physically inaccessible locations is possible.

Optimization of the design

Lighting simulation enables the optimization of lighting solutions to improve visual appearance, energy efficiency and comfort. Various objectives, e.g. homogeneous lighting or a higher-quality visual appearance, can be pursued by adjusting various parameters.

Visualization and presentation

It provides a visually appealing and realistic representation of lighting effects, which is particularly useful for presenting design concepts to customers or stakeholders.

Supporting sustainability

By optimizing lighting, energy consumption can be reduced, contributing to the sustainability and cost efficiency of products.

Promoting safety

In areas ranging from working environments to machinery safety specifications, visual displays and cues can contribute to significant safety.
