RAPID prototyping, ELLIPSOIDS, AUTOMOBILE lighting, STREET lighting, ANTENNAS (Electronics), and LIGHT emitting diodes
The article focuses on designing freeform surfaces, which are used for illumination applications such as headlights, streetlights, and antennas. It says that illumination systems using freeform surfaces may result to compact systems with long lifetime, low power consumption, and high system efficiency, if combined with light-emitting diodes (LEDs). It highlights the dominant surface construction methods such as flux mapping method and the method of supporting ellipsoids.
RAPID prototyping, LIGHTING, LIGHT emitting diodes, and ELECTROLUMINESCENT devices
The article offers information on the use of freeform optics as a light collectors and uniformizers for spotlight and directional-floodlight general-illumination light emitting diodes (LEDs). An LED freeform illumination lens-design approach developed by researchers at the University of Arizona is mentioned. It states that the goal of a good freeform optical design for LED floodlighting is to obtain good intensity uniformity throughout the floodlit area.
