In freeform optics, the optimization is limited due to large number of parameters present in it. This limitation was overcome by a technique known as optimization using freeform deformation (OFFD). Though this technique proved to work well, it has left many challenges to the optical designer. These challenges are solved by providing mathematical design techniques. This implementation transformed the OFFD into an intelligent tool replacing the optical designer's efforts during the design process.

A practical introduction to state-of-the-art freeform optics design for LED packages and applications By affording designers the freedom to create complex, aspherical optical surfaces with minimal or no aberrations, freeform design transcends the constraints imposed by hundreds of years of optics design and fabrication. Combining unprecedented design freedom with precise light irradiation control, freeform optics design is also revolutionizing the design and manufacture of high quality LED lighting. The first and only book of its kind, Freeform Optics for LED Packages and Applications helps put readers at the forefront of the freeform optics revolution. Designed to function as both an authoritative review of the current state of the industry and a practical introduction to advanced optical design for LED lighting, this book makes learning and mastering freeform optics skills simpler and easier than ever before with: Real-world examples and case studies systematically describing an array of algorithms and designs—from new freeform algorithms to design methods to advanced optical designs Coding for all freeform optics algorithms covered—makes it easier and more convenient to start developing points of freeform optics and construct lenses or reflectors, right away Case studies of a range of products, including designs for a freeform optics LED bulb, an LED spotlight, LED street lights, an LED BLU, and many more Freeform Optics for LED Packages and Applications is must-reading for optical design engineers and LED researchers, as well as advanced-level students with an interest in LED lighting. It is also an indispensable working resource design practitioners within the LED lighting industry.

Diese Arbeit befasst sich mit den Auswirkungen der Degradation, der in der LED eingesetzten Packagematerialien auf die Gesamtalterung von LED-Bauteilen. Dazu werden die im Bauteil vorkommenden Fehlermechanismen anhand der Alterung der verwendeten Packagematerialien beschrieben, vorhergesagt und miteinander in Verbindung gesetzt. Aus den gewonnenen Erkenntnissen werden Ansätze zur Verbesserung der Langzeitstabilität von LED-Baugruppen abgeleitet. - This work deals with the material degradation of LED package materials and their contribution to degradation of the whole LED device. The occurring failure modes within the LED package are described and predicted by the degradation of the used package materials. Based on these findings approaches for long lifetime LEDs are derived.

Das menschliche Auge kann sich aufgrund seines Dynamikumfangs innerhalb kürzester Zeit an verschiedenste Lichtsituationen anpassen. Ist der Dynamikumfang des Auges nicht ausreichend, kommt es zur Blendung. Um die Auswirkungen auf die Sehleistung und deren Verlauf zu beschreiben, fehlt eine geeignete objektive Messmethode. Diese wurde im Rahmen dieser Arbeit entwickelt und validiert. - Due to its dynamic range, the human eye can adapt to a wide variety of light situations within a very short time. If the dynamic range of the eye is insufficient, glare occurs. There is no suitable objective measurement method to describe the effects on visual performance and its course. This was developed and validated as part of this work.

Beim Ansatz eines Laserscannerscheinwerfers zur Realisierung von adaptiven Lichtfunktionen werden sechs Laserdioden auf einen Mikrospiegel gelenkt, welcher durch seine schwingende Bewegung eine ausgedehnte Lichtverteilung auf einem Weißlichtkonverter erzeugt ehe diese auf die Fahrbahn projiziert wird. Diese Arbeit beschreibt diesen Ansatz und zeigt Methoden zur Homogenitätsbewertung von Scheinwerferlichtverteilungen. - The approach of a laser scanning headlamp for adaptive light functions includes six laser sources which are deviated on a micro mirror. The oscillation of that mirror generates an extended light distribution on a white light converter which is then projected on the road. This work describes that approach and presents methods to evaluate the homogeneity of headlamp light distributions.

Modernste Scheinwerfer können beliebige Symbole auf die Straße projizieren. Die möglichen Anwendungsszenarien sind Fahrerassistenz/-information oder Kommunikation mit anderen Verkehrsteilnehmern. Neben allen Möglichkeiten darf auch die Gefahr durch Ablenkung nicht außer Acht gelassen werden. Die vorliegende Arbeit zeigt Möglichkeiten auf, das Ablenkpotenzial zu operationalisieren und zu quantifizieren. Mithilfe dieser Bewertung kann dann über eine Zulassung der Lichtfunktion entschieden werden. - Modern headlights are able to project any desired symbol directly onto the street. Feasible applications are driver assistance, information or communication with other traffic participants. Besides all the possibilities the risk of distraction can’t be neglected. The present work offers a way to operationalize and quantify this risk. Based on this evaluation a possible homologation can be determined.
