Accelerated Development with Virtual Prototyping for Lighting Industry

OPTIS is implementing since many years solutions for the automotive industry which help to reduce the development time and cost for headlamps. In this presentation, we show that the same virtual prototyping process has benefits in the field of general lighting. The process generally starts with light design. In a virtual scene, it is possible to highlight some regions and such to define the needed flux by sketching light. By specifying the luminaire positions it is possible to calculate automatically the needed angular light distributions (IES, Eulumdat) and such the number of needed light sources as LEDs can be specified. In the next step these targets are given to the engineering department which will develop the needed optical shapes like reflectors and lenses. Doing this with CAD tools the design can be highly automated using parametric design. Now the resulting photometry data will be compared to the initial targets and to industry standards. Due to CAD integration, it is also possible to take into account production variances and to check the reliability of the chosen design. It will also be important to check human vision aspects like glare doing for example an UGR analysis and color uniformity analysis. By using the correct material and surface data it is possible to achieve a physics based rendering of the luminaire which helps the final customer to get already an impression of the lighting without the necessity to produce a real prototype.

Finally, the simulation results can be put back into VR systems which helps the final customer to experience the luminaires in a virtual showroom. We will show this process on a luminary example in order to make the process clearly visible to the audience.
