In applications such as concert show lighting, architectural lighting, and cinema projection, good color mixing is essential. The optics design in front of a RGBW LED source must include optimization for color uniformity as well as beam shape. A common solution is to...
Updated July 2020. Freeform lenses (including TIR lenses) and lightpipes are the two most common types of LED illumination optics. They can be made using injection molding and are affordable. Glass materials are not common for general illumination, but are used for...
All roadway lamps must be designed according to specific standards. The most popular ones are a US standard called "IESNA RP 8-00 Roadway lightning" and a European one called "CIE 140-2000 Road lighting calculations". In the case of CIE 140-2000, the standard only...
To assist with the computation of the paths of millions of light rays, optical engineers use specialized software to design and simulate optical systems. Zemax is the most popular optical design software and the one I prefer. It includes many built-in functions...
