Thermal design considerations for high-power single-chip LEDs
With advanced high-power packaging technology, large-area chips offer a number of advantages over arrays, according to Bob Karlicek, John Graff and Dave Sciabica.
PhlatLight™ LEDs from Luminus Devices are designed specifically to replace arrays of smaller LED chips or lamps in almost any application requiring high lumen output in a small area. By using photonic lattice technology, advanced wafer bonding techniques and high-power packaging technology, these devices can easily be made more than ten times (10X) larger than conventional LED power chips and can be driven reliably at much higher current densities than conventional LEDs.
