Future Directions in LED Applications

  • Chapter
  • First Online:
Thermal Management for LED Applications

Part of the book series: Solid State Lighting Technology and Application Series ((SSLTA,volume 2))

Abstract

This chapter describes possible future development directions of solid-state lighting from a high-level materials, devices, and system applications perspective. Since solid-state lighting is likely the highest volume future LED application and is a completely new form of lighting technology, advances in semiconductor and packaging materials, LED devices, and new lighting systems designs are convolved with the evolution of business models and new capabilities brought by new corporate entrants to the rapidly evolving global solid-state lighting business. Examining the development of future LED applications is, therefore, complicated, and it is helpful to briefly set the stage with a brief review of current and emerging LED technology trends and applications.

Notes

  1. 1.

    Droop refers to the drop in LED light production efficiency with increasing current density common in GaN based LEDs, particularly longer wavelength blue and green LEDs. The droop effect is different from efficiency reduction caused by LED heating due to higher operating current which can be minimized through adequate thermal design.
