LED lighting came a long way in 2008. The solid-state lighting
revolution can be seen everywhere: From traffic lights or the
headlamps of passing cars, to display lighting and even the
Times Square ball that marked the end of the year.
2008 saw the introduction of functional luminaires based on
power LEDs, such as IST’s DL LED down-light – a clear sign that
power LEDs will soon belong in the wider illumination market. To
illustrate this point, the street-lighting design shown on page 10
demonstrates a level of performance that competes with
traditional light sources.
Wider acceptance has been backed by the emergence of solid-state
lighting standards that allow customers to objectively
compare LED fixtures, as well as standard optics, drivers and
controllers for specific applications.
This rate of progress looks set to continue in 2009. LED
technology is offering improved light output and efficiency;
and supporting devices are enabling other advantages. For
example, the LM3421 controllers offer increased efficiency
using a sense voltage of just 100mV (see page 090125); and Philips’
Xitanium drivers enable efficient operation of LED systems up
to 150W (see page 090136).
To accelerate new designs based on emerging LED technology,
Future Lighting Solutions has released a range of powerful new
design tools: The usable-light , LED-reliability and QLED tools
enable power-LED applications to be designed quickly and safely.
Multicolour-mixing and CRI tools assist with the creation of high-quality
tunable white-light fixtures. Some of these tools are
highlighted in our example design shown on page 090140.
Alternatively, these tools can be accessed on the Future Lighting
Solution’s website along with other design resources that make LED-lighting
solutions simple: www.futurelightingsolutions.com
