Ring optical mixer for LED with truncated surfaces

LED modules emitting a luminous flux, implement near-field luminance distribution or colorimetric distribution depending on emitters location. In the far field there is complete mixing of luminous flux, both in terms of quantity as well as because of distribution color parameters. To achieve these mixing light in a short distance of the LEDs is necessary to use optical elements. The article presents the results of creating light distribution and luminance by using the ring optical elements with truncated outer surfaces.
