Light by Design

LED is the new standard in lighting. However, lighting devices based on LED require an optical system to create a desired light output. In the program ’Light by Design’ we investigate advanced physical models describing the interaction of light with optical systems and develop efficient numerical simulation methods for the design of these systems. The ultimate goal is to develop advanced simulation tools that can be used for virtual prototyping.





Research tracks

The ILI researchers who are participating at the Light by Design program are mainly part of the Computational Illumination Optics group of the department of M&Cs. It is one of the few mathematics groups worldwide working on optical design problems from illumination optics. It has 3 research tracks: freeform designimproved direct methods and imaging optics.

Using numerical simulation methods, we can compute the shape of the reflector that converts a uniform parallel beam of light into the illuminance pattern corresponding to the grey-scale image of the painting ”Girl with a Pearl Earring”.
