Secondary Optics Design

Considerations for SuperFlux LEDs

Secondary optics are those optics which exist outside of the LED package, such as reflector

cavities, Fresnel lenses, and pillow lenses. Secondary optics are used to create the desired

appearance and beam pattern of the LED signal lamp.

The following section details the optical characteristics and optical model creation for Lumileds

SuperFlux LEDs. In addition, simple techniques to aid in the design of collimating reflectors,

collimating lenses, and pillow lenses are discussed.
