Computer software, Rapid prototyping, Lighting, Energy consumption, and Optics
The article offers information on software tools that design freeform optics for illumination. Topics discussed include newly developed tools integrated with commercial illumination software quickly create freeform reflective and refractive surfaces, freeform optics tailor resulting illumination pattern to meet system requirements such as enhance the visual appeal and improve energy efficiency.
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.
