The CAUSTIX team works on the realization of optical components for anidolic optics: it consists in designing mirrors or lenses that distort the luminous flux emitted by a light source in order to conform to a desired light distribution.
The problems of anidolic optics are difficult to solve. To date, there is no software capable of solving these problems automatically. This results in a trial-and-error approach, consisting in modifying a surface little by little, until it reflects light in the right directions and with the right intensity. Such processes are costly in terms of engineering time and technician hours.
The CAUSTIX software allows to calculate the shape of a lens or a mirror that refracts or reflects the light emitted by a LED towards a desired light distribution in an automatic way, and in order to meet many industrial constraints.
The advantages of the CAUSTIX solution, identified for the moment, are the following:
- Reduction of iterations in the design phase of an optical system
- Improvement of the quality of lighting
- Increased innovation capabilities with the ability to test and validate multiple configurations at lower cost
- Compliance with lighting standards in highly constrained environments.
State of progress
CAUSTIX has developed a software that allows to take into account extended light sources and to integrate geometrical constraints (size, curvature, shape). These problems can be found at the industrial level. At this stage, the project will obtain data on light sources and targets corresponding to industrial problems in order to set up a POC.
The markets that can use CAUSTIX technology are those requiring strict compliance with lighting standards.
- Automotive (headlights, tail lights, positioning lights - The "intelligent" headlight)
- Railway (Signal lights - Headlamp)
- Public lighting (urban lighting, sports equipment lighting, emergency interior lighting)
- Aeronautics (Landing and taxi lights, position lights)
- Medical: medical lighting system.
- Lighting for operating rooms
- Trend to watch: implementation of lighting standards for the protection of photo-sensitive people
- Defense: possible interest in identifying a source based on a given distribution.
