How Substrate Materials Affect LED Reliability

The solid-state lighting industry continues to develop LEDs with higher lumens per watt, in alignment with Haitz Law, which states that the cost per lumen falls by a factor of 10 every decade and the amount of light generated per LED increases by a factor of 20. These advancements are driving the need for packaging and thermal substrate technologies that deliver better thermal management, are more reliable, and are cost-efficient.
