ABSTRACT

Light-emitting diodes (LED) have become the 4th generation light source since the turn of the century. In the past decade, people witnessed more and more applications of general lighting applications using LEDs. There is no doubt that solid-state lighting has become commodity in the comercial markets. Many people are wondering about what next waves of LED R&D should be focused on. Based on the speaker’s observation, there are three emerging areas worth noting, namely, UV-LED, visible light communications (VLC), and micro-LED display. All of these are for non-lighitng applications. This presentation will briefly touch on these emerging areas and then focus on UV-LED. The intention is to bring the on-going technology trend to the awareness of active researchers on LED so that they can put their resources and efforts on the hot spot. In addition to the fundamentals of UV-LED and relevant concerns in packaging, certain applications will be introduced to demonstrate the features of UV-LED which are different from conventional general lighting.
