The color of the emitted light depends on the semiconductor material and composition, with LEDs generally classified into three wavelengths: ultraviolet, visible and infrared.The wavelength range of commercially available LEDs with single-element output power of at least 5 mW is 360 to 950 nm. Each wavelength range is made from a specific semiconductor material family,...Photonics HandbookIllumination Design and Analysis Software: A Vital Tool in the Designer’s Kit: Optical systems design and analysis software is a key element in an optical engineer’s toolkit. Simulation allows virtual tinkering with a system problem before ever creating — and in some cases eliminating — a prototype. The results can be analyzed to determine real system performance and to suggest changes to optimize the design and enhance performance.Illumination design has developed rapidly to include not only automotive headlamps and street lamps, but also backlit displays, fluorescent panel lighting, light-emitting diode or laser sources, and...Photonics Handbook
