Abstract

This invention pertains to a method for accomplishing broadband, even and efficient LED light using a LED light source comprising of several LEDs (101) and in which the spectrum is modified using filters. The combination of light from the LEDs together with the LEDs and filters (203) is used to create a desired distribution of spectrum. The light from the LEDs is being channeled with lenses (104, 202) to separate bundles of optical fiber (150, 201) which subsequently are joined together into one final bundle (204).
