Simulation enables optimum LED street light heat-sink design (MAGAZINE)

Djordje Zivanovic and Richard Ozaki describe a thermal-design methodology that enabled the development of a new self-cleaning heat sink for an outdoor LED luminaire using simulation tools. The original version of this article can be found...

CSEM announces EU-funded LASSIE-FP7 large-area SSL module project

Switzerland based R&D lab will lead collaborative research charged with developing SSL modules that combine the reliability and performance of LEDs with tunable organic elements in planar modules for use in luminaires such as architectural recessed troffers. The...

LEDs chart a new path for tunnel lighting (MAGAZINE)

LEDs are proving their benefits in most outdoor area lighting applications, but the point sources integrated in solid-state lighting fixtures are an especially good match for tunnel applications. Dale Kane explores specific challenges posed by tunnels and how to...

Understand the true cost of LED choices in SSL systems (MAGAZINE)

The LED component cost is only one facet of the design and production cost for solid-state lighting (SSL) systems. Other factors that impact the overall cost, performance, and lifetime of general lighting products include the suitability of components for the intended...
