Status & future of laser technology

Julian Carey, Product & Technical Marketing Manager, SLD Laser

Julian Carey, Product and Technical Marketing Manager at SLD Laser attended LpS 2018 in Bregenz. LaserLight had recently demonstrated record-breaking results with 750 lumens emitted from a 300 micron diameter window, which was a good reason to talk to him about the status quo of laser technology, which applications are currently applicable, SLD Laser's strategies and goals, and the future prospects for this technology.

Hermetic Polymer-Free White LEDs for Harsh Environments

AlGaInN-based white LED can achieve lifetimes of up to 100,000 h depending on junction temperature and current density. However, state of the art silicone encapsulated LEDs with powder-based phosphors reveal a strong dependence of field lifetimes on environmental conditions such as humidity, corrosive gas and air pollutant exposure. An interesting alternative to polymer-dispersed phosphors are luminescent ceramics. The article explains how they can be used as a hermetic, light converting cap material. Further properties and the advantage of completely avoiding polymers are also discussed.

Fast and Accurate Determination of LED Junction Temperatures

Junction temperature of LEDs is one crucial parameter to being thoroughly observed. In this paper, the authors will at first describe the importance of Tj for LED systems including RGB and white LEDs. Then they will present techniques from literature and recently in-house developed novel methods. Results in selected general lighting and automotive lighting applications will be demonstrated.

AI – Today and Tomorrow

Recently, Artificial Intelligence has emerged as an evolutionary force in almost every industry, demonstrating its potential to radically change existing processes. In common literature, AI is interchangeably used with Machine Learning, for which various tools have already become commonplace. The author discusses AI in the context of the lighting industry where the scope of applications of AI is similarly quite broad, impacting the various stages involved in the lighting life cycle such as design, installation, commissioning and configuration.

LiFi

LiFi as a Paradigm-Shifting 5G Technology

There are many misconceptions about LiFi, a wireless communication technology that uses the infrared and visible light spectrum for high speed data communication. The authors will explain what Light-Fidelity (LiFi) is and argue why it is a 5th Generation (5G) technology. Peak transmission speeds of 8 Gbps from a single light source have been demonstrated, and complete cellular networks based on LiFi have been created. Besides discussing numerous misconceptions, the potential impact this technology can have across a number of existing and emerging industries will be explained as well as new applications that LiFi can unlock in the future.
