LIGHTING
Japan’s Eco-point Program transforms market for LED lamps
A government-sponsored program in Japan could serve as a model for other countries seeking to transform their domestic retail market for LED lamps, explains PHILIP JESSUP.


LUMINAIRES
Building blocks of intelligent lighting design help create successful LED products
Engineers working on LED-based designs need to make the right decisions when faced with some basic building-block questions to yield successful, intelligent SSL products, explains GAVIN HESSE.


STANDARDS
ANSI evaluates revisions to SSL chromaticity standard
A working group within ANSI is evaluating ways to improve an existing standard that defines how to communicate the chromaticity of white-light SSL products to end users, explains JIANZHONG JIAO.

BACKLIGHTING
LED-based poster-box reference design overcomes optical and cost challenges
LEDs can be used to replace fluorescent tubes in advertising poster boxes, offering long-term savings in energy and maintenance costs, which are set against the higher up-front cost of the LED system, explains MATTHIAS SCHMIDER.




DESIGN FORUM
LED lighting and control systems evolve for optimal efficacy
New SSL system designs and control architectures will allow LED-based lighting to better realize the efficacy potential of the technology, explains JOE DENICHOLAS.



LAST WORD
The time for intelligent LED-based lighting systems is now
LED–based light sources are uniquely controllable, and intelligent SSL systems with adaptive controls can greatly enhance energy savings, so what are we waiting for, asks MAURY WRIGHT?
