LEDs Optimized for Architectural and Emergency Vehicle Lighting Applications

As a mainstay in architectural and emergency vehicle lighting, colour LEDs bring about intrinsic advantages such as durability and reliability, in addition to the possibility of delivering controlled “colour light performances.” In recent years, however, the evolving architectural and emergency vehicle lighting landscape has necessitated developing colour LEDs that can enable the most effective and optimized system design…

Beyond Lighting: State-of-the-Art and Future Applications of LED Lighting

Over the past decades light has been used to diagnose disease, enable digital communication through fibre optics, and generate power through solar panels. Most recently, advances in solid state lighting has transformed the most commonplace source of light, the lightbulb. The latest LED technology is not only making lighting more sustainable but also allows unprecedented control of light quality, colour, intensity as well as the inclusion of data and computation that was unimaginable with incandescent or fluorescent lighting…

Optical Measurement Guidelines for High-Power LEDs and Solid State Lighting Products, Part 2

Users sometimes report measurement discrepancies for the same LED when measured on two different systems. This could arise either because of errors with the system or different levels of accuracies between the two systems. This section describes several common sources of equipment errors and provides suggestions to minimize those…

Learn How Li-Fi Works from Its Inventor, Harald Haas

Some day the last leg of our communication networks might not depend on a modulated radio signal but on a modulated light signal from an LED bulb in a desk lamp or ceiling fixture. IEEE Senior Member Harald Haas has developed a visible light communication system he calls light fidelity, or Li-Fi, which relies on nanometer waves in the infrared and visible light part of the electromagnetic spectrum to transmit data generated by an LED bulb fitted with a microchip…

How PoE Lighting Technology Will Affect Distributors

The lighting market is changing and electrical distributors are at risk of losing aspects of the lighting segment. While it’s doubtful that they’ll lose the majority in the “near” future (5, 10, 15, 20 years), it is being whittled away by a number of factors (see below)…

PoE Lighting Revenue Forecast to Increase 1100% by 2026

Since Power over Ethernet (PoE) lighting is in its infancy, there is still skepticism about using PoE technology for lighting. The success of PoE technology for other use cases, such as phone systems, has not translated into widespread acceptance for the lighting market. However, a Navigant research report forecasts that global revenue for PoE lighting will grow from an estimated US$35.8 million in 2016 to US$419.9 million in 2025…

A Short History of Safety Norms For LEDs

What came first: the chicken or the egg? In technical files the answer is simple: first comes the product, then the standard. In 1993, when Nichia introduced the blue LED (based on GaN), the issue of photo biological safety was taken into consideration. The International Electrotechnical Commission (IEC) decided to include LEDs in the laser product category and related norms (IEC 60825).
