22mm collimators that hide die pattern from Gaggione

Gaggione has introduced a 16mm diameter range of optical collimators for LED lighting, optimised not to image the die – giving a smooth beam as a consequence. Made in PMMA (acrylic) and called LLC22, they are “dedicated to single and multi-chip high power LEDs. The range is based on our patented non-chip-imaging technology. The LED chip will ...
