Small Area-Based LED Luminaire Design

摘要

The objective of this three-year project is to develop GaN-based LED arrays, specifically addressing the thermal, optical, electrical and mechanical requirements for the incorporation of such array into viable solid-state luminaries. The scope of work encompassed individual small-area chip shaping and contact designs to improve LED efficiency and facilitate incorporation into arrays with associated electrical power handling and downconversion technologies to achieve target efficiency at the desired color point. The array elements then were matched to appropriately designed LED arrays including thermal management elements with minimal overall thermal resistance to ambient to ensure lowest possible LED operating temperatures. Finally, the resulting LED arrays were combined with a custom luminaire enclosure that has been designed to specifically address the thermal, optical, and electrical requirements of the LED luminaire prototype.
