A method for projecting useful life of LED lighting systems
This study investigated a non-invasive method to determine the junction temperature of AlGaInP light-emitting diodes (LEDs) in a system. Because the primary cause for the AlGaInP LED degradation is junction temperature, this method can be used to predict LED life. The primary objective of this study was to verify that wavelength shift could be used to estimate accurately the junction temperature of 5mm epoxy encapsulated AlGaInP LEDs. Based on previous studies, the authors chose to focus on the measurement of junction temperature and its relationship to LED degradation.

Standard for White Color LED Lighting Fixtures
This document outlines a proposed definition of standard for white color LED lighting fixtures manufactured by ATG Electronics and the way for mass production of orders.

How to Select Residential LED Under-cabinet Lighting
LED fixtures for kitchen and display cabinets have become more readily available. But from one fixture to the next, there may be differences in light output, light color, lighting distribution…This article tells you how to select residential LED under-cabinet lighting from the aspects of cost, quality, reliability, installation, replacement and availability.

Standards required for further penetration of solid-state lighting
The solid-state lighting industry urgently needs standards to assist its growth and to avoid hype and negative reactions. The good news is that standards work is proceeding rapidly in a number of directions. And UL (Underwriters Laboratories) has been working towards a safety standard that will cover the sale of LEDs and LED fixtures in the North American market.

LED Life for General Lighting
Traditionally, the definition of life for light sources is defined at the point which 50% of the lamps fail under specified conditions. However, all necessary components in a LED lighting system will determine useful life time. This paper provides the measurement method for LED components.

LED Lighting Systems Q & A
Questions and answers on LED general information, electrical properties, thermal properties, optical properties, application etc.

LED Technology Trends
This article will describe trends in the LED market and the consequences on the technical roadmap of LED products. This will prescribe the focal points and direction of the upcoming manufacturing technologies. Two main trends are reinforcing at the moment. The first is an ongoing miniaturisation; the second one is the increasing number of power applications coming up due to higher chip efficiencies.

Solid-state lighting market poised for dramatic growth
Improvements in white LED performance and price will attract the attention of larger lighting companies, LED-based designs will become more efficient, and solid-state lighting products will greatly increase their penetration of the mainstream general illumination market.
