SC389: Design of Non-Imaging Illumination Systems

This course covers the basics of illumination system design with emphasis on computer aided techniques. It begins by exploring the fundamental principles of illumination systems. An overview of various types of systems and light sources are presented and issues with Light Emitting Diodes (LEDs) are covered extensively. Detailed instruction on the tailored edge ray design (TED) method of nonimaging optics and algorithms for segmented reflector design of automotive headlamps will be covered. Design of lightpipes and other precision plastic-molded optics are covered along with mathematical optimization procedures. Scattering of light can be very useful in the design of illumination systems, particularly in backlighting applications. Techniques to handle these effects are discussed and the design of painted LCD backlights are covered in detail.
