Micro-optics promote use of LEDs in consumer goods
Module size and power limitations impose major challenges for the design of optics for portable consumer products. Diffractive micro-optics can play an important role in meeting these needs.
Since LEDs are basically broad-area wide-angle emitters, designing and realizing such micro-optics in a compact form is a challenge. The introduction of customized diffractive optical elements (DOEs), made possible by recent advances in design and fabrication technology, has resulted in a major advance in producing compact, functional and cost-effective LED lighting modules.+++++++
