Abstract

Today’s high-power illumination is mainly based on LED technology. Continuing trends are increased luminous power on decreasing emitting surfaces. This leads to growing technical requirements of optics that are useable for modern LED systems: Firstly, the increasing power densities require transparent materials that are durable when exposed to high temperatures or luminous fluxes. Here, polymeric materials as polycarbonate, PMMA or silicone quickly exceed their material limits when used in such conditions. Secondly, the smaller LED size allow for the design of smaller optical solutions. This means, the size of luminaires can be shrunk without any disadvantage for the optical performance. This comes with increasing requirements for system accuracy and geometrical deviations of the optics. Glass, shaped with modern manufacturing techniques, is a promising solution for these requirements. In this paper, we show two different approaches for automotive front lights. The first is non-isothermal glass molding of aspherical lenses. This method allows for the fast manufacturing of precision glass lenses including all structures needed for accurate mounting. These lenses can be used in imaging systems for modern front lights. The second method covers glass injection molding of complex 3D-optics. Here, tiny light guide optics are used for typical automotive front light distributions.
