Abstract
Two novel LED recycling schemes using either recycling light pipes or recycling "collars" show promise in significantly increasing the brightness of the LED sources. Preliminary experimental data show significant brightness enhancement, especially with a relatively high chip reflectivity and/or high mirror blockage factor. Further improvement may be expected when various system parameters are optimized.
