MARKETS
Life beyond lighting: LED market shows growth in other areas
Although lighting is the fastest-growing and most exciting application for LEDs, there is plenty of activity and technical development in other market sectors, as Wolfgang Lex of Osram Opto Semiconductors explains to Tim Whitaker.
LIGHTING
Time to stop ignoring light losses from residential fixtures
Luminaire efficacy testing will help buyers and builders choose efficient residential lighting fixtures and accelerate the rate of energy savings achieved, writes James Brodrick.
SHOW REPORT
LEDs part of the green theme at Electronica
Green electronics and LED lighting were major themes at the biennial Electronica tradeshow in Munich, Germany, reports editor-in-chief Tim Whitaker.
REPLACEMENT LAMPS
LED retrofits offer clear and effective benefits
LED replacements for fluorescent tubes provide energy savings without costly infrastructure changes, writes Dave Simon of ilumisys, Troy, Michigan, USA.
OPTICAL MODELING
Software predicts performance of phosphor down-converted white LED designs
Predictive modeling benefits from sophisticated algorithms and accurately measured data inputs, writes Chao-Hsi Tsao, Edward Freniere and Linda Smith.
ENERGY EFFICIENCY
DC power distribution favors LED lighting
A low-voltage DC power standard could accelerate the conversion to LED-SSL lighting and create an enabling infrastructure that prepares the workplace for the future of DC power, writes Brian Patterson and Paula Ziegenbein.
TECHNOLOGY
Novel lighting technologies offer a future alternative to LEDs
A broad and exciting diversity of emerging illumination technologies is a natural and healthy response to current lighting challenges, writes Hassaun Jones-Bey.
DRIVERS
Driver IC design ensures optimum performance of LED backlighting
LED backlight drivers are the “wizards behind the curtain” that ensure a display’s visual performance will remain as specified regardless of the operating conditions, says Michael Jennings.
