Abstract

Constant LED developments show increasing levels of luminous flux and power densities. In particular, automotive and entertainment industries are requesting mechanically and optically stable light guides for their new mid to highest-power lighting solutions. The switch from polymer to glass optics comes with improved temperature resistance, higher optical performance and better longevity of the systems [1, 2]. Even highest-power LEDs can be driven at maximum current obtaining best light output. The option of directly implementing micro structures on the output aperture of glass light guides gives the opportunity to customize final color mixing and light scattering over a wide range. This reduces the amount of required components and subsequently the total system costs.
