Brief Summary
Computer-generated optical element to spectrally separate and concentrate light for lighting, displays, spectroscopy, and related applications.
Problem Statement
Color mixing is essential to achieve white light illumination for a variety of applications. Currently, there are limited methods for high efficiency mixing of a given set of input light beams.
Technology Description
University or Utah Researchers have developed a novel, computer-generated optical element, called a polychromat, to spectrally separate and concentrate sunlight. The result is a uniform output beam of white light with high efficiency and color stability. Because of its flexible design, it can produce uniform or non-uniform output intensity distributions for use in conjunction with color light sources such as light-emitting diodes for highly efficient color mixing in lighting, displays, spectroscopy, and related applications.
Benefit
- Provides significantly more control over output light than previously possible.
- With high power conversion efficiency, provides for lower materials usage and lower overall costs.
- Flexibility of the polychromat enables use in a wide range of applications.
