In summary, matching a light pipe to an LED ensures optimum performance. To be the most effective the light pipe entry point must be placed as near to the top of the LED as possible and the LED should be surrounded by the light pipe retaining wall. The LED angle of radiation should be kept small to most effectively capture the light in the light pipe and to prevent leakage to other nearby light pipes. In applications with multiple LEDs and light pipes, proper attention to binning is necessary to provide consistent color performance.
