Illumination design for extended sources based on phase space mapping

Abstract

Abstract. Illumination design usually requires the shaping of a specific irradiance distribution from a given light source. For point-like sources or collimated laser beams various methods exist to construct the shape of the refractive and/or reflective surfaces within the optical system. However, for extended sources, an additional feedback or optimization loop is usually required and limitations are not clear. We propose an analysis and design method that includes the source extension from the very beginning. The method is based on phase space mapping of the source radiance distribution onto the target irradiance distribution. We illustrate the method with several examples. © The Authors.

An Energy Conservative hp-method for Liouville’s Equation of Geometrical Optics

“…The analysis of light propagation using a phase space description provides a new approach to understanding optical systems [17,29,35]. Phase space, being defined as the collection of all positions and direction coordinates of rays, provides a complete description of the spatial and angular distribution of light.…”

“…Next, we have to approximate the integrals in Eq. (29). The test function φ is chosen to be in the same basis as the solution ρ, resulting in a Galerkin method.…”

An Ader Discontinuous Galerkin Method on Moving Meshes for Liouville's Equation of Geometrical Optics

“…The optical interface cutting the cell in two pieces makes it rather complicated to construct a Taylor expansion, since at the optical interface we have to apply the jump condition (5). Instead, we use that ρ remains invariant along a light ray, i.e., we apply (2) combined with jump condition (5). In particular, at z = z t we know the solution, hence, at a given (final) three-dimensional point (z f , x f ) we apply the following relation…”

GaN-based mini-LED matrix applied to multi-functional forward lighting

“…3 . The optical design follows the rule of light field technology 30 . Since the etendue of the light source received by each segment is different, the specific segments (called HL segments) with smaller etendue are used to project low beam with a high-contrast cutoff line, and the other segments are projected downward for ground illumination.…”
